The study evaluated the effects of Mimusa pudica (M. pudica) leaf extract on type 2 diabetes in rats fed high fructose diet (HFD). Rats were fed either control diet or HFD for 14 days, following which the diet was fortified with M. Pudica at a dose of 500 mg/kg BW. After 8 weeks, HFD caused deleterious metabolic effects, including increased body weight, hyperglycemia, hyperinsulinemia, dyslipidemia and liver dysfunction. Further, rats fed HFD alone showed increased activities of hepatocellular enzymes in plasma and lipid deposition in liver. Treatment with M. pudica significantly reduced the body weight, improved insulin sensitivity, managed the dyslipidemia and reduced liver damage towards normal. Histopathology of the liver confirmed the changes induced by HFD and the M. pudiac treatment significantly reversed towards normality. These data suggest that M. pudica treatment improve insulin sensitivity and attenuates fat accumulation in liver.

In order to study the adaptive anatomical structures during nastic movement of Mimosa pudica L., anatomical structures of main pulvinus, common petioles, rachis and leaflets were compared with Albizia julibrissin Durazz. (taken as control). The anatomical structures of main pulvinus and common petiole of M. pudica were different from that of A. julibrissin. Upon stimuliti, the protoplast volume of M. pudica in the lower cortical parenchyma cells become smaller than that in upper ones, a feature seldom found in A. julibrissin. There were found many reticulate lacunas on the two side of adaxial petiole of M. pudica, but nil in A. julibrissin. Similarly some ill developed lacunas were found in the pulvinus of rachis and leaflet of M. pudica, but absent in A. julibrissin. It appears that reticulate lacunas in common petiole of M. pudica are responsible for its strong nastic movement. The main sensitivity position lies at the base of common petiole, where the lower cortex is more sensitive than the upper cortex, and the ordinal sensitivity positions are rachis and leaflets.

Mimosa pudica (Linn.) ( M. pudica L.) is a plant used in some countries to treat anxiety and depression. In the present study we investigated the effects of an aqueous extract of M. pudica L. on mouse anxiety-like behaviour using the elevated T maze, and on regulation of dorsal raphe nucleus (DRN) 5-hydroxytryptamine (5-HT) neuronal activity using an in-vitro mouse brain slice preparation. Acute treatment with M. pudica L. extract had an anxiolytic effect on behaviour in the elevated T maze, specifically on inhibitory avoidance behaviour. Acute application of the extract alone had no effect on the activity of DRN 5-HT neurones. However, when co-applied with the GABAA receptor agonist THIP (4,5,6,7-tetrahydroisoxazolo[5,4- c]pyridin-3-ol), the extract enhanced the inhibitory effect of the THIP on DRN 5-HT neurones. These observed effects of M. pudica L. on both behaviour and GABA modulation of 5-HT neuronal activity are similar to the effects of diazepam, the established anxiolytic and positive modulator of the GABAA receptor. This study suggests that the aqueous extract of M. pudica L. contains a positive modulator of GABAA receptor function and provides impetus for further investigation of the neuropharmacologically active constituents of the extract.

Objective: Mimosa pudica is a traditional medicinal plant. The natural antioxidant compounds from plants mop up the free radicals causing cell damage and maintain the biological systems. The aim of the present study is to evaluate the free radical scavenging potential of the ethanolic and aqueous thorn extracts of M. pudica.Methods: The ethanolic and aqueous thorn extracts of M. pudica were analyzed for the phytochemicals and for free radical scavenging activity by 1, 1 diphenyl 1-2-picric hydrazine (DPPH), 2, 2’-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS), and nitric oxide free radical scavenging method.Results: Flavonoids, saponins, glycosides, alkaloids, terpenoids, and coumarins were the phytoconstituents revealed in ethanolic and aqueous thorn extracts of M. pudica. At 250 μg/mL concentrations, aqueous thorn extracts of M. pudica exhibited 73.41% radical scavenging activity by DPPH method and 26.10% inhibition by nitric oxide free radical scavenging method. However, the ethanolic extracts of M. pudica thorns exhibited 73.35% inhibition by ABTS free radical scavenging method at 250 μg/mL concentrations.Conclusion: The results obtained suggest that the plant extracts from M. pudica could serve as a potential source of antioxidant in slowing down the process of aging and age-related or oxidative stress-related degenerative diseases. Moreover, the isolation of bioactive principle responsible for the antioxidant activity and formulation of novel therapeutic agents can be further studied.

Background: The World Health Organization included snakebite envenomation among Neglected Tropical Diseases in 2017. The importance of natural products from plants is enormous, given that most prescribed drugs originate from plants. Among this is Mucuna pruriens and Mimosa pudica, with many registered patents asserting their health benefits. Objective: This study investigated the in vitro neutralizing effects of Mucuna pruriens seed and Mimosa pudica root extracts on venoms of Naja nigricollis and Bitis arietans. Methods: In mice, the LD50 and phytochemical analysis of M. pruriens and M. pudica plant extracts were carried out prior to the evaluation of their haemolytic and fibrinolytic effect. Their effects on the activities of phospholipase A2 (PLA2) were also assessed. Results: At a concentration of 50 mg/ml, both plant extracts were found to neutralize the fibrinolytic activity of N. nigricollis, but 400 mg/ml was required to neutralize the fibrinolytic activity of B. arietans. In haemolytic studies, 50 mg/ml concentration of M. pruriens extract suppressed haemolysis caused by N. nigricollis venom by 70% but at the same concentration, M. pudica extract reduced haemolysis by 49.4%. M. pruriens, at 50 mg/ml concentration, only inhibited phospholipase A2 activity by 7.7% but higher concentrations up to 400mg/ml had no effect against the venom of N. nigricollis; at 200 mg/ml. M. pudica extract inhibited PLA2 activity by 23%. Conclusion: The results suggest that M. pruriens and M. pudica may be considered as promising antivenom agents for people living in a snake-bite prone environment.

Due to the emergence of increased level of antibiotic resistance among uropathogens, urinary tract infections or UTI became a severe menace to mankind affecting millions of people every year. At this context, the present study was designed to compare the antagonistic activity exhibited by Mimosa pudica and Moringa oleifera against UTI causing bacteria and the phytochemical constituents possessed by them. Various solvent extracts of the leaves of M. pudica and M. oleifera were prepared and evaluated for their antagonistic activities against urinary tract infection causing bacteria by agar well diffusion method. Also the phytochemical screening of these two plants was done qualitatively. The results of the antagonistic activity of M. pudica and M. oleifera revealed that the leaves of both the plants possess remarkable antagonistic properties against bacteria causing UTI. The phytochemical analysis revealed the presence of secondary metabolites such as flavonoids, saponins, steroids, tannins and coumarins. From the above study, it can be concluded that the leaves of M. pudica can be considered as a potential agent of antagonistic properties that can be used to develop novel drugs against bacteria that cause UTI.

ABSTRACT The objective of the present research is to characterize the phytotoxic activity of geopropolis from the Jandaira bee (Melipona subnitida Ducke) in the state of Ceará in Northeast Brazil and to analyze its effects. Extracts were prepared in 80% v/v grain alcohol at 0.25, 0.5, 0.75, and 1.0%. Their effects were determined on seed germination, radicle elongation, and hypocotyl growth of the pasture weeds malícia (Mimosa pudica) and mata-pasto (Senna obtusifolia). Extract phytotoxicity varied as functions of plant species, application dosage, and plant organ. M. pudica was more sensitive to the inhibitory effects of geopropolis than S. obtusifolia. There was a phytotoxic effect of 50% (PE50) for S. obtusifolia in terms of seed germination and in rootlet development near the maximum applied concentrations. M. pudica had PE50 and PE90 at the minimum concentration (0.25%) and near the maximum (1.00%), respectively. Thus, geopropolis extracts from the Jandaira bee (M. subnitida) are potentially phytotoxic to certain plant species.

Bacterial symbionts present in the indeterminate-type nitrogen (N)-fixing nodules of Mimosa pudica grown in North and South India showed maximum similarity to Ralstonia taiwanensis on the basis of carbon-source utilization patterns and 16S rDNA sequence. Isolates from the nodules of M. pudica from North India and South India showed identical ARDRA (Amplified Ribosomal DNA Restriction Analysis) patterns with Sau3AI and RsaI, but AluI revealed dimorphy between the North Indian and South Indian isolates. Alignment of 16S rDNA sequences revealed similarity of North Indian isolates with an R. taiwanensis strain isolated from M. pudica in Taiwan, whereas South Indian isolates showed closer relatedness with the isolates from Mimosa diplotricha. Alignment of nifH sequences from both North Indian and South Indian isolates with that of the related isolates revealed their closer affinity to α-rhizobia, suggesting that nif genes in the β-rhizobia might have been acquired from α-rhizobia via lateral transfer during co-occupancy of nodules by α-rhizobia and progenitors of R. taiwanensis, members of the β-subclass of Proteobacteria. Immunological cross-reaction of the bacteroid preparation of M. pudica nodules showed strong a positive signal with anti-dinitrogenase reductase antibody, whereas a weak positive cross-reaction was observed with free-living R. taiwanensis grown microaerobically in minimal medium with and without NH4Cl. In spite of the expression of dinitrogenase reductase under free-living conditions, acetylene reduction was not observed under N-free conditions even after prolonged incubation.Key words: symbiotic nitrogen fixation, Mimosa pudica, rhizobia, phylogeny, 16S rDNA, nifH, Ralstonia taiwanensis.

The β-rhizobium Cupriavidus taiwanensis is a nitrogen-fixing symbiont of Mimosa pudica. Nod factors produced by this species were previously found to be pentameric chitin-oligomers carrying common C18:1 or C16:0 fatty acyl chains, N-methylated and C-6 carbamoylated on the nonreducing terminal N-acetylglucosamine and sulfated on the reducing terminal residue. Here, we report that, in addition, C. taiwanensis LMG19424 produces molecules where the reducing sugar is open and oxidized. We identified a novel nodulation gene located on the symbiotic plasmid pRalta, called noeM, which is involved in this atypical Nod factor structure. noeM encodes a transmembrane protein bearing a fatty acid hydroxylase domain. This gene is expressed during symbiosis with M. pudica and requires NodD and luteolin for optimal expression. The closest noeM homologs formed a separate phylogenetic clade containing rhizobial genes only, which are located on symbiosis plasmids downstream from a nod box. Corresponding proteins, referred to as NoeM, may have specialized in symbiosis via the connection to the nodulation pathway and the spread in rhizobia. noeM was mostly found in isolates of the Mimoseae tribe, and specifically detected in all tested strains able to nodulate M. pudica. A noeM deletion mutant of C. taiwanensis was affected for the nodulation of M. pudica, confirming the role of noeM in the symbiosis with this legume.

O objetivo deste trabalho foi avaliar a tolerância de estirpes de Cupriavidus necator a zinco, cádmio, cobre e chumbo, além de determinar a eficiência simbiótica das estirpes mais tolerantes em associação a espécies leguminosas com potencial para revegetação. A tolerância foi testada em meio LB, suplementado com 2,5; 5,0; 7,5; 10; 12,5 e 15 mmol L-1 de ZnSO4.7H2O, CdSO4.8H2O, CuSO4.5H2O e PbCl2, respectivamente, em comparação ao controle sem adição de metal. Determinou-se a eficiência simbiótica das quatro estirpes de C. necator mais tolerantes aos metais avaliados (UFLA02-71, UFLA02-73, UFLA01-659 e UFLA01-663), as quais foram inoculadas nas espécies: Leucaena leucocephala, Enterolobium contortisiliquum, Acacia mangium, Mimosa caesalpiniifolia, M. pudica, M. pigra e M. acutistipula. Em vasos com solos, avaliaram-se L. leucocephala, M. pudica e M. caesalpiniifolia e as estirpes UFLA01-659 e UFLA02-71, selecionadas na avaliação de eficiência simbiótica. A estirpe UFLA02-71 proporcionou incrementos de matéria seca da parte aérea de 870% em M. caesalpiniifolia, enquanto que UFLA01-659 proporcionou 885% em M. pudica e 924% em L. leucocephala. As estirpes UFLA01-659 e UFLA02-71, além da alta tolerância a metais pesados, apresentaram eficiência em fixar nitrogênio, em simbiose com essas leguminosas, em solos com rizóbios nativos capazes de nodulá-las, e devem ser avaliadas quanto ao seu potencial de utilização em programas de recuperação de áreas degradadas.

As sessile organisms, plants do not possess the nerves and muscles that facilitate movement in most animals. However, several plant species can move quickly in response to various stimuli (e.g., touch). One such plant species, Mimosa pudica L., possesses the motor organ pulvinus at the junction of the leaflet-rachilla, rachilla-petiole, and petiole-stem, and upon mechanical stimulation, this organ immediately closes the leaflets and moves the petiole. Previous electrophysiological studies have demonstrated that a long-distance and rapid electrical signal propagates through M. pudica in response to mechanical stimulation. Furthermore, the spatial and temporal patterns of the action potential in the pulvinar motor cells were found to be closely correlated with rapid movements. In this review, we summarize findings from past research and discuss the mechanisms underlying long-distance signal transduction in M. pudica. We also propose a model in which the action potential, followed by water flux (i.e., a loss of turgor pressure) in the pulvinar motor cells is a critical step to enable rapid movement.

Purpose: To investigate the toxicity, clinical outcome and anthelmintic effects of M. pudica in vitro and in vivo.Methods: Dried leaves of M. pudica were extracted using 70 % methanol cold maceration method. Acute toxicity inquiry was evaluated using Lorke’s method. Anthelmintic effects were investigated in vitro using the egg hatch assay and in vivo using Heligmosomoides bakeri experimentally infected adult albino mice. Coprological and haematological parameters were recorded during the experiment while the serological analysis and post mortem worm burden were assessed at the conclusion of the research.Results: No mortality was recorded in oral acute toxicity test up to a dose of 5000 mg/kg. A probit-log analysis of the percentage egg hatch of the extract and albendazole gave lethal concentration 50 (LC50) values of 1.160 and -1.042, respectively. A reduction in worm count was observed in all the extracttreated groups post mortem, with the maximum extract group having the least worm count (p < 0.05). Treatment with extract resulted in improvement in the haematological parameters. Serum chemistry revealed no significant differences (p > 0.05) in alanine aminotransferase and blood urea nitrogen in all groups. However, a dose-dependent increases in the total protein and albumin was observed.Conclusion: These results show that although M. pudica has weak anthelmintic effects compared to albendazole (standard anthelmintic), in vivo and in vitro, at the doses used in this study, nonetheless, it reduces worm burden and improves haematologic parameters, serum total protein, albumin and overall weight gain of the treated mice. Thus, increased doses may be effective in anthelmintic chemotherapy.

ABSTRACT
Basic Health Research (Riskesdas) revealed that mental health problems prevalence increased from 6% (2013) to 9.8% (2018). If left untreated, it has the potential to become a mental disorder that requires complex medication and affects productivity. The facts revealed that the availability and the utilization of mental disorder drugs in primary health care are still limited. There is a possibility of unwanted side effects, as well. Plants are expected to be one of the sources for the discovery of new drugs that have the least possible side effects. As having been identified in the Research of Medicinal Plants and Jamu (Ristoja) 2012, Mimosa pudica (putri malu) is believed to have the potential in treating mental disorders. This paper aimed to provide scientific information about the prospects of M. pudica as an antidepressant, anti-anxiety, and mood disorders treatment. A semi-systematic literature review was used to analyze 61 references based on searches for relevant keywords, with open access references limit from 1995 to 2020. The results show that M. pudica has antidepressant activity, anti-anxiety, helps overcome mood disorders, and also acts as a muscle relaxant. The toxicity study confirms its safety in beneficial doses. The human LD50 is 15.516 g/kg, indicating a reasonable safety limit. As this plant can be grown anywhere without special treatment, it will be a potential source for medicinal ingredients to treat anxiety and depression. Further research is also needed to explore therapeutic dosage in humans and its interactions with other drugs or herbs.

ABSTRAK
Riskesdas mencatat gangguan mental emosional mengalami kenaikan dari 6% (2013) menjadi 9,8% (2018). Bila tidak tertangani dengan baik, gangguan mental emosional berpotensi menjadi gangguan jiwa yang perlu penanganan kompleks dan berkontribusi pada hilangnya produktivitas penderitanya. Ketersediaan obat di pelayanan kesehatan primer untuk gangguan ini masih rendah, penggunaan obat antidepresi dan antiansietas yang dibatasi, serta adanya efek samping yang tidak diinginkan adalah permasalahan yang perlu dicari solusinya. Tumbuhan diharapkan menjadi salah satu solusi sumber penemuan obat baru yang memiliki efek samping sekecil mungkin. Salah satu yang diyakini berpotensi untuk mengatasi gangguan mental emosional adalah Mimosa pudica L. (putri malu). Tumbuhan ini telah diidentifikasi dalam Riset Tumbuhan Obat dan Jamu 2012, dan memiliki potensi yang baik untuk dieksplorasi lebih lanjut sebagaimana bukti profil farmakologisnya terhadap gangguan mental emosional. Tulisan ini bertujuan memberikan informasi kajian ilmiah potensi tumbuhan M. pudica untuk membantu mengatasi gangguan depresi, ansietas, dan gangguan suasana hati. Metode yang digunakan adalah telaah semi-sistematik, menganalisis 61 referensi berbasis pencarian kata kunci yang relevan, dengan batasan referensi akses terbuka tahun 1995-2020, dan hasil dideskripsikan secara kualitatif. Hasil menunjukkan bahwa M. pudica memiliki aktivitas antidepresi, antiansietas, membantu mengatasi gangguan suasana hati, serta bermanfaat sebagai relaksasi otot. Hasil studi toksisitas mengkonfirmasi keamanan dalam dosis manfaat. LD50 manusia sebesar 15,516 g/kg BB, menunjukkan batas keamanan wajar. Tumbuhan ini dapat tumbuh dimana saja tanpa perawatan khusus sehingga berpotensi menjadi sumber bahan obat, terutama pengobatan kecemasan dan depresi dengan lebih sedikit efek samping. Interaksinya dengan obat atau herbal lainnya masih perlu dieksplorasi karena belum tersedia data yang cukup, sehingga penggunaannya tetap harus berhati-hati.

We report the isolation of Fonsecaea pedrosoi from thorns of the plant Mimosa pudica L. at the place of infection identified by one of our patients. Clinical diagnosis of chromoblastomycosis was established by direct microscopic examination and cultures from the patient's lesion. The same species was isolated from the patient and from the plant. Scanning electron microscopy of the surface of the thorns showed the characteristic conidial arrangement of F. pedrosoi. These data indicate that M. pudica could be a natural source of infection for the fungus F. pedrosoi.

Los efectos alelopáticos son una herramienta para el control de arvenses más práctica y viable en los agroecosistemas, estas reacciones naturales tienen múltiples efectos, que van desde la inhibición o estimulación de los procesos de crecimiento de las plantas vecinas, hasta la inhibición de la germinación de semillas. En este trabajo se evaluó la actividad alelopática de extractos brutos de Copaifera pubiflora (Benth) sobre la germinación de Mimosa pudica (Lineo) para generar nuevos posibles métodos de control de M. pudica, y al mismo tiempo ampliar el conocimiento y bioprospección de especies endémicas de la Orinoquia, como lo es C. pubiflora. Se utilizaron extractos etanólico, hexánico y medio acuoso, de hojas y corteza de C. pubiflora, en concentraciones de 7, 5 y 2 % pv y un diseño multifactor categórico, junto con pruebas preliminares de identificación de metabolitos secundarios para el extracto con mayor actividad alelopática. Los resultados mostraron que los extractos etanólico y en medio acuoso de corteza y hojas, tienen actividad alelopática, sobre la germinación de M. pudica. Además, con las pruebas preliminares se logró determinar la posible presencia de metabolitos secundarios que son reconocidos por generar alelopatía. © 2016. Acad. Colomb. Cienc. Ex. Fis. Nat.

Mimosa pudica Linn is a well-known perennial herb and is traditionally used in ayurvedic medicine for the treatment of various illnesses. Despite its abundance in nature, the therapeutic potential of this invasive weed is deemed to be underappreciated in Malaysia. Previous studies have found an abundance of bioactive compounds associated with potent antioxidant properties in all parts of the plant. However, the optimum parameters required for the extraction of antioxidant compounds are still unknown. Therefore, the present study aimed to optimize the solvent extraction parameters of M. pudica using response surface methodology to enrich the accumulation of antioxidant compounds in the extracts. The effects of the optimized M. pudica extracts were then evaluated on the cell viability and glucose uptake ability in a 3T3-L1 adipocyte cell line. The highest total phenolic (91.98 mg of gallic acid equivalent per g of the dry extract) and total flavonoid content (606.31 mg of quercetin equivalent per g of the dry extract) were recorded when using 100% ethanol that was five-fold and three-fold higher, respectively, as compared to using 50% ethanol. The extract concentration required to achieve 50% of antioxidant activity (IC50 value) was 42.0 µg/mL using 100% ethanol as compared to 975.03 µg/mL using 50% ethanol. The results indicated that the use of 100% ethanol solvent had the greatest impact on the accumulation of antioxidant compounds in the extract (p < 0.05). Cell viability assay revealed that all extract concentration treatments recorded a viability level of above 50%. Glucose uptake assay using 2-NBDG analog showed that the cells treated with 50 µg/mL extract combined with insulin were five-fold higher than the control group. Given the high antioxidant and antidiabetic properties of this plant, M. pudica can be easily highlighted as a plant subject of interest, which warrants further investigation for nutraceutical prospects.

Ixora coccinea L. (santan) and Mimosa pudica L. (makahiya) ethanolic and aqueous extracts were screened for their in vitro antacid potentials using the preliminary antacid test, determination of acid neutralization capacity, acid neutralizing effect, duration of consistent neutralization, and buffering capacity. Phytochemical screening and quantification of alkaloids were also done and the alkaloid content was correlated to the in vitro antacid potentials of the extracts. Among the extracts, the M. pudica aqueous extract gave the best preliminary antacid test result (1.0066±0.0083 pH) and acid neutralization capacity (0.0711±0.0038 mmol H+). Its aqueous extract showed comparable acid neutralizing effect (3.507% acid neutralized) on gastric juice with that of its ethanol extract (3.509% acid neutralized). On the other hand, the I. coccinea aqueous extract had the highest acid buffering capacity (0.0701±0.0020 mmol H+/pH). Both aqueous extracts gave the longest duration of neutralization with 9±1.732 minutes. All the extracts were tested positive for flavonoids, indoles, tannins, anthraquinones, anthrones, and alkaloids, with the I. coccinea aqueous extract having the highest alkaloid content (18.0282±1.2607% w alkaloid/w extract). This study provides the first reported proof of the antacid activities of I. coccinea and M. pudica. Further tests, including mouse model assays, are suggested to determine the efficacy of the extracts in vivo.

Several β-proteobacteria have been isolated from legume root nodules and some of these are thought to be capable of nodulating and fixing N2. However, in no case has there been detailed studies confirming that they are the active symbionts. Here, Ralstonia taiwanensis LMG19424, which was originally isolated from Mimosa pudica nodules, was transformed to carry the green fluorescent protein (gfp) reporter gene before being used to inoculate axenically-grown seedlings of M. pudica and M. diplotricha. Plants were harvested at various intervals for 56 days after inoculation, then examined for evidence of infection and nodule formation. Nodulation of both Mimosa spp. was abundant, and acetylene reduction assays confirmed that nodules had nitrogenase activity. Confocal laser scanning microscopy (CLSM) showed that fresh M. pudica nodules with nitrogenase activity had infected cells containing bacteroids expressing gfp. In parallel, fixed and embedded nodules from both Mimosa spp. were sectioned for light and electron microscopy, followed by immunogold labeling with antibodies raised against gfp and nitrogenase Fe (nifH) protein. Significant immunolabeling with these antibodies confirmed that R. taiwanensis LMG19424 is an effective N2-fixing symbiont of Mimosa spp. Both species were infected via root hairs and, in all respects, the nodule ontogeny and development was similar to that described for other mimosoid legumes. The nodules were indeterminate with a persistent meristem, an invasion zone containing host cells being invaded via prominent infection threads, and an N2-fixing zone with infected cells containing membrane-bound symbiosomes.

The antifungal activity of crude extracts of M. pudica Linn. was evaluated by determining the minimum inhibitory concentration (MIC) of the solvent extracts. Subsequently, an antifungal assay was carried out by determining the inhibition of radial growth in PDA plates added with plant extracts. MIC value of crude extracts was 15.00, 18.50 and 19.50 µg/mL for 95% ethanol, dichloromethane and acetone extracts, respectively. Concerning the inhibition of radial growth, ethanol crude extracts of M. Pudica was most effective and exhibited highest antifungal activity of 55.65% at 10.00 µg/mL, 54.02% at 1.00 µg/mL, 50.95% at 0.10 µg/mL, and 48.70% at 0.01 µg/mL against C. gloeosporioides., respectively. The highest yield was found in 95% ethanol at 73 mg/g. The higher yield was presented when the higher polar solvents were used in this experiment. Since factors such as solvent of extraction may influence the properties of derived crude extract, different extraction methods may be of interest for further trial.

The corrosion inhibitory activity of mild steel in 1M hydrochloric acid solution by Mimosa pudica leaves extract was examined by the weight loss method. The result reveals that the leaves extract performs well as a good eco-inhibitor of the corrosive action of HCl on mild steel. Inhibition efficiency obtained for the extract rises with higher concentration and exposure time but falls with increasing temperature. The mechanism of the adsorption mode of the extract’s molecules fits well with Langmuir adsorption isotherm which suggests that the phytochemical constituents, (tannins, saponins, flavonoids, alkaloids, phenols, and quinones) as qualitatively displayed by the preliminary screening, adsorb onto the metal surface by forming monolayer films. Kinetics study shows that the rate of metal corrosion in the acidic medium is a first-order reaction that is concentration-dependent.

Extratos hidroalcoólicos de parte aérea, raízes e sementes e extratos brutos de sementes de Canavalia ensiformis foram preparados, visando identificar e caracterizar os efeitos potencialmente alelopáticos sobre a germinação de sementes e o alongamento da radícula das plantas daninhas Mimosa pudica, Urena lobata, Senna obtusifolia e Senna occidentalis. Os trabalhos foram desenvolvidos em condições controladas de 25 ºC de temperatura e fotoperíodo de 12 horas, para o bioensaio de germinação, e 24 horas, para o de alongamento da radícula. Os efeitos foram aquilatados tendo por contraste (testemunha) a água destilada. Os resultados variaram em função da espécie receptora, da concentração e da parte da planta utilizada no preparo dos extratos. A inibição da germinação das sementes e do alongamento da radícula foi diretamente proporcional à concentração do extrato, com as mais intensas inibições observadas na concentração de 4%. Independentemente da espécie receptora, as sementes, seguidas das raízes, foram as principais fontes de substâncias químicas com atividades potencialmente alelopáticas no feijão-de-porco. A análise dos diferentes extratos brutos revelou que as substâncias químicas com atividades potencialmente alelopáticas presentes nas sementes do feijão-de-porco têm polaridade compreendida entre o acetato de etila e o metanol. Para o extrato bruto metanólico, concentrações a partir de 0,4% inibiram completamente a germinação das espécies receptoras, enquanto para M. pudica e S. occidentalis concentrações de 0,6 e 0,8% proporcionaram inibições da ordem de 100% para a germinação das sementes dessas espécies. A sensibilidade das espécies aos efeitos potencialmente alelopáticos variou na seguinte ordem decrescente: M. pudica > S. occidentalis > S. obtusifolia > U. lobata.

RESUMO: Descrevem-se, na pele de equídeos, lesões de natureza mecânico-traumática causadas por espinhos de Mimosa spp. Dentre as três espécies da planta identificadas como responsáveis pelas lesões, M. setosa estava presente em maior quantidade (80%) e M. debilis e M. pudica encontravam-se em menor proporção na pastagem. Ocorreram três surtos de dermatite ulcerativa em períodos chuvosos de abril a maio de 2013, dezembro de 2013 a fevereiro de 2014 e abril a maio deste mesmo ano. Vinte e cinco equinos do Setor de Reprodução Animal da Universidade Federal Rural do Rio de Janeiro apresentaram, na pele, lesões ulcerativas com contornos irregulares, exsudato hemorrágico, recobertas por crostas. As lesões localizavam-se sobretudo nas regiões de quartela, boleto, articulação escapulo-umeral, lábios superior e inferior, focinho, narinas, bochechas e chanfro. Sete animais foram biopsiados e o exame histopatológico revelou ulceração da epiderme e infiltrado inflamatório constituído por macrófagos e neutrófilos, delimitado por tecido de granulação subjacente. Em alguns casos, foram observados microespículos das referidas plantas (tricomas hirsutos) em meio à reação inflamatória. O diagnóstico de dermatite cutânea causada pela ação traumática da planta baseou-se na presença de Mimosa spp. na pastagem, nas características e localização das lesões na pele dos equinos, nos achados histopatológicos e na recuperação após a retirada dos animais do pasto.

ABSTRACT rRNA gene sequencing and PCR assays indicated that 215 isolates of root nodule bacteria from two Mimosa species at three sites in Costa Rica belonged to the genera Burkholderia, Cupriavidus, and Rhizobium. This is the first report of Cupriavidus sp. nodule symbionts for Mimosa populations within their native geographic range in the neotropics. Burkholderia spp. predominated among samples from Mimosa pigra (86% of isolates), while there was a more even distribution of Cupriavidus, Burkholderia, and Rhizobium spp. on Mimosa pudica (38, 37, and 25% of isolates, respectively). All Cupriavidus and Burkholderia genotypes tested formed root nodules and fixed nitrogen on both M. pigra and M. pudica, and sequencing of rRNA genes in strains reisolated from nodules verified identity with inoculant strains. Inoculation tests further indicated that both Cupriavidus and Burkholderia spp. resulted in significantly higher plant growth and nodule nitrogenase activity (as measured by acetylene reduction assays) relative to plant performance with strains of Rhizobium. Given the prevalence of Burkholderia and Cupriavidus spp. on these Mimosa legumes and the widespread distribution of these plants both within and outside the neotropics, it is likely that both β-proteobacterial genera are more ubiquitous as root nodule symbionts than previously believed.

<p class="Abstract">The aim of present investigation was to validate its folk use in the treatment of ulcerative colitis in the rat model. Sprague Dawley rats were divided into nine groups with six animals in each group. The rats received seven days of pretreatment with chloroform, ethyl acetate or ethanolic extract of <em>Mimosa pudica</em>. For induction of ulcerative colitis, rats were administered with 2 mL of 4% acetic acid solution intrarectally. Ulcer index, macroscopical study of the colon, myeloperoxidase and malondialdehyde levels in colon tissue and blood, and histopathology of the colon tissue were studied. Intrarectal instillation of acetic acid caused increased ulcer index, colonic myeloperoxidase and malondialdehyde. Pretreatment with <em>M. pudica</em> ethanolic extract (400 mg/kg) significantly lowered the ulcer index, colonic myeloperoxidase and malondialdehyde as compared with the standard drug prednisolone. The present investigation demonstrates that the ethanol extract of <em>M. pudica</em> leaf is effective in the treatment of ulcerative colitis.</p><p class="Abstract"><strong>Video Clip of Methodology:</strong></p><p class="Abstract">Embedding or block making: 24 sec <a href="https://www.youtube.com/v/Y1I4tKYMLsE">Full Screen</a> <a href="https://www.youtube.com/watch?v=Y1I4tKYMLsE">Alternate</a></p><p class="Abstract">Tissue processing: 19 sec <a href="https://www.youtube.com/v/7nYpxL2qPhg">Full Screen</a> <a href="https://www.youtube.com/watch?v=7nYpxL2qPhg">Alternate</a></p><p class="Abstract">Section cutting: 33 sec <a href="https://www.youtube.com/v/_amFL9kNLBw">Full Screen</a> <a href="https://www.youtube.com/watch?v=_amFL9kNLBw">Alternate</a></p>

As áreas inundáveis localizadas na bacia dos rios Amazonas e Solimões são denominadas várzeas. A inundação é um evento natural que promove mudanças na estrutura e composição florística dessas comunidades. O conhecimento da diversidade de espécies é de fundamental importância para o entendimento da dinâmica da regeneração natural de espécies nos ecossistemas amazônicos. Este trabalho teve como objetivo levantar a composição florística do solo do fundo do lago do Manaquiri-AM, em um período de seca excepcional, ocorrida em 2005, na Amazônia. Foram realizadas coletas de material botânico em duas áreas do lago, em novembro de 2005; para a amostragem, utilizou-se um quadrado de madeira de 0,36 m², atirado aleatoriamente por 20 vezes em cada local de estudo. A vegetação emergente foi de 5.958 indivíduos, distribuídos em sete famílias e nove espécies. As famílias mais representativas em número de espécies foram Poaceae e Cyperaceae. Cyperus esculentus e Luziola spruceana foram as mais frequentes, e Mimosa pudica e Alternanthera sessilis, as de maior abundância. C. esculentus e M. pudica apresentaram maior número de indivíduos, de densidade e de valor de importância. As espécies de plantas encontradas neste estudo mantiveram sua capacidade de crescer e se desenvolver mesmo após longo período submersas.

We analyzed specimens collected from June/2010 to October/2011 and collections deposited in the ALCB, HRB, HUEFS, and MBM herbaria. We registered 11 species distributed in two sections: Mimosa sect. Batocaulon DC. (Mimosa acutistipula (Mart.) Benth. var.acutistipula, M. adenophylla var. mitis Barneby, M. arenosa (Willd.) Poir. var. arenosa, M. caesalpiniifolia Benth., M. lewisii Barneby, M. misera Benth., M. piscatorum Barneby, M. quadrivalvis var. leptocarpa (DC.) Barneby, and M. tenuiflora (Willd.) Poir.) and Mimosa sect. Mimosa (M. pudica var. tetrandra (Humb. & Bonpl. ex Willd.) DC. And M. sensitive L. var. sensitiva). The main characters used for delimitation of the species were inflorescence morphology, number of pinnae, leaflets, perianth elements and stamens, as well as aspects from the fruit. The species occurs mainly open areas and more degraded along trails on sandy soils. Keys for identification of species, descriptions, illustrations and comments about geographic distribution and flowering and fruiting periods of the species are presented.

The rapid turgor movements of Mimosa pudica and some carnivorous plants have long stimulated the interest of botanists. In addition, it is becoming evident that slower responses of plants to mechanical stimuli, such as coiling of tendrils and thigmomorphogenesis, are common phenomena. Electrophysiological studies on mechano-perception have been carried out in M. pudica and carnivorous plants, and have established that the response to mechanical stimulation is composed of three steps: perception of the stimulus, transmission of the signal, and induction of movement in motor cells. The first step is due to the receptor potential, the second and third steps are mediated by the action potential. In this article, the mechanisms of responses to mechanical stimuli of these plants are considered. Since higher plants are composed of complex tissues, detailed analysis of electrical phenomena is rather difficult, and so the mechanism for generating the receptor potential had not yet been studied. Characean cells have proved to be more amenable to the study of the electrophysiology of plant membranes because of their large cell size and the ease by which single cells can be isolated. Recent progress in studies of the receptor potential in characean cells is also discussed.

Phytosociological studies were conducted in three vegetation types in the WS II area of Wayanad Wildlife Sanctuary. In each vegetation type, 85 quadrats (10 x 10 m) were laid to quantify the vegetation. Natural forest showed comparatively higher species richness than plantation and vayal (swamps/low lying grassland). In natural forest 96 plant species were present while it was 70 and 66 respectively in plantation and vayal. Fabaceae was the dominant family in all the three vegetation types. The natural forest was dominated by Chromolaena odorata, followed by Lantana camara, Mimosa pudica, Terminalia elliptica, Glycosmis pentaphylla. In the plantations, Chromolaena odorata, Tectona grandis, Mimosa pudica and Glycosmis pentaphylla showed dominance. The vayal was dominated by Arundinella leptochloa. The second most dominant species in the vayal was Chromolaena odorata. Other dominant species were Kyllinga nemoralis and Sporobolus tenuissimus. Among the three, vayal recorded the highest Simpson Diversity Index. The highest Berger-Parker Dominance Index value in plantation indicates the presence of dominant species. Natural forests recorded highest Margalef Richness Index and the least was in vayal. The highest Pielou’s Wiener Equitability Index in vayal indicated all species are evenly distributed.

Rhizobia, the nitrogen-fixing symbionts of legumes, are polyphyletic bacteria distributed in many alpha- and beta-proteobacterial genera. They likely emerged and diversified through independent horizontal transfers of key symbiotic genes. To replay the evolution of a new rhizobium genus under laboratory conditions, the symbiotic plasmid of Cupriavidus taiwanensis was introduced in the plant pathogen Ralstonia solanacearum, and the generated proto-rhizobium was submitted to repeated inoculations to the C. taiwanensis host, Mimosa pudica L. This experiment validated a two-step evolutionary scenario of key symbiotic gene acquisition followed by genome remodeling under plant selection. Nodulation and nodule cell infection were obtained and optimized mainly via the rewiring of regulatory circuits of the recipient bacterium. Symbiotic adaptation was shown to be accelerated by the activity of a mutagenesis cassette conserved in most rhizobia. Investigating mutated genes led us to identify new components of R. solanacearum virulence and C. taiwanensis symbiosis. Nitrogen fixation was not acquired in our short experiment. However, we showed that post-infection sanctions allowed the increase in frequency of nitrogen-fixing variants among a non-fixing population in the M. pudica–C. taiwanensis system and likely allowed the spread of this trait in natura. Experimental evolution thus provided new insights into rhizobium biology and evolution.

Semiconducting polymer based X-ray detector design is quite interesting and challenging task for the researchers. Because of low X-ray attenuation of polymers, the device becomes insensitive. In the paper we report a way through the introduction of fluorescent nanoparticles to increase the X-ray detection probability.The Mimosa pudica fibre was coated with CdSe-CdS quantum dot-in-rods on the surface by chemical dipping processes. The fibre morphology and microstructure have been analysed by TEM and SEM techniques. The well-oriented CdSe-CdS quantum dot-in-rods have been observed in TEM with an aspect ratio (rod length ̸ rod diameter) of 28.7×3.5 nm and quantum yield 78% of a sharp emission peak at 545 nm. The CdSe-CdS quantum dot-in-rods coated M. pudica fibre, as observed in SEM, possesses a honeycomb structure of the nano-material. It is expected that the interaction between static-electric field of the fibre and the field produced by the above quantum particle causes to form a well-ordered honeycomb cover on the fibre of the surface. The goal of this study is to confirm the feasibility of the X-ray imaging detection system based on the quantum size effect on coated conducting fibre.

A study on the effect of light illumination introduced to the leaves of Mimosa pudica was carried out using different light intensities. The leaves will open gradually from the closed condition after the light was illuminated. Plant of M. pudica was placed in the dark box during measurement meanwhile the Petiole (part of the stem) of the plant was at normal position (hanging up). The camera was fixed to the box to monitor the leaves’ movement continuous and real time. By using this method the change of the top view area of the leaves could be observed. A crossed line was drawn on the image recorded and was measured its length. The calculation of the length gives the percentage of leaves at open during the observation time. Ultrasonic apparatus was also used to monitor the change of leaves. From the results, at an illumination intensity of 200 Lux, the percentage of leaves to open completely with respects to the observation time was found to increase nonlinearly by taking the time of 25 minutes. For intensities of 400 Lux, the trend of curve was also similar but increase rapidly. The ultrasonic signals show much stable at 200 Lux comparing to 400 Lux that was fluctuating. That may be due to the relatively faster movement of the leaves to open. This natural phenomenon is interesting and may introduce any change of natural indication that could be explored for further applications.

Benign prostatic hyperplasia, a non-cancerous condition of unknown etiology, is the most common prostatic disease in men globally. The present study investigated the possible ameliorative effects of aqueous extracts of Mimosa pudica on experimentally-induced prostatic hyperplasia in Wistar rats.
Twenty adult, male Wistar rats weighing 120-180 g were randomly divided into four groups (A, B, C, D) of five animals each. Group A, normal control, was given corn oil only; Group B rats were hormone-treated. Groups C and D rats were hormone and extract treated, and received continuous doses of 300 μg and 80 μg of testosterone and estradiol, respectively, on alternate days for three weeks subcutaneously in the inguinal region. The extract-treated rats received an additional 400 mg/kg b. w and 800 mg/kg b. w. of M. pudica orally for another four weeks. Immediately after induction of benign prostatic hypertrophy, some animals were randomly selected and sacrificed for gross inspection of prostate enlargement, prostate specific antigen analysis (PSA) and sperm count evaluation. These procedures were repeated again after four weeks of extract treatment. The prostates were excised and processed routinely for paraffin embedding and stained with hematoxylin and eosin (H&E).
Results obtained showed significant (P<0.05) reduction in PSA levels, increase in sperm count and also a reversal of histological hyperplastic changes.

Mimosa pudica seed mucilage (MPM) is composed of glucuronoxylan, which is a swellable, pH-responsive and non-toxic biomaterial. Herein, we aimed to extract MPM from M. pudica seeds (MP seeds) to ascertain optimization of extraction conditions to get highest yield by response surface methodology, via Box-Behnken design (RSM-BBD). MPM was extracted from MP seeds by a hot water extraction method. The effects of four different parameters on the extraction yield of MPM were evaluated: pH of the extraction medium (1–10), seed/water contact time (1–12 h), the temperature of extraction medium (30–90 °C), and seed/water ratio (1:5–1:35 w/v). The maximum yield of MPM obtained by Design-Expert software was 10.66% (10.66 g/100 g) at pH 7, seed/water contact time of 6 h, extraction temperature of 50 °C, and seed/water ratio of 1:20 w/v. The p values of ANOVA were found to be less than 0.0001, which indicated that the extraction yield of MPM was significantly affected by all the study parameters. The results revealed that pH and extraction temperature were the most significant factors affecting the yield of MPM. MPM in compressed tablet form showed pH-responsive on–off switching behavior at pH 7.4 and 1.2 in a reversible manner. MPM in compressed tablet form sustained the release of itopride for 16 h following a super case-II transport mechanism and zero-order release kinetics.

Senna alata é uma espécie daninha frequente em pastagens da região amazônica. Suas folhas apresentam propriedades medicinais capazes de influenciar a germinação e o desenvolvimento de outras plantas. Objetivou-se neste estudo a prospecção química e a avaliação da atividade alelopática dos compostos presentes nas folhas de S. alata. O material vegetal foi seco, triturado e submetido à extração exaustiva, com solução água:metanol (3:7). O extrato obtido foi então fracionado por coluna cromatográfica por via úmida. As frações mais puras foram submetidas à espectroscopia de Ressonância Magnética Nuclear, para determinação das fórmulas estruturais das moléculas. Na avaliação dos efeitos das substâncias químicas isoladas, utilizaram-se as concentrações de 50, 100, 150 e 200 ppm, tendo como eluente solução hidrometanólica (3:7 v/v). As frações foram adicionadas em placas de Petri e seus efeitos avaliados sobre a germinação de sementes e o alongamento da radícula e hipocótilo de três espécies daninhas de áreas de pastagens: Mimosa pudica, Senna obtusifolia e a própria S. alata. Os compostos com atividade alelopática encontrados em folhas de S. alata pertencem à classe dos flavonoides glicosilados, cujo núcleo aromático é um kaempferol, e causaram maior inibição sobre o crescimento da radícula e sobre a germinação de S. obtusifolia e M. pudica. Já os efeitos autotóxicos desse composto são pouco significativos para o desenvolvimento da plântula e nulos sobre a germinação.

Nitrogen-fixing symbionts of legumes have appeared after the emergence of legumes on earth, approximately 70 to 130 million years ago. Since then, symbiotic proficiency has spread to distant genera of α- and β-proteobacteria, via horizontal transfer of essential symbiotic genes and subsequent recipient genome remodeling under plant selection pressure. To tentatively replay rhizobium evolution in laboratory conditions, we previously transferred the symbiotic plasmid of the Mimosa symbiont Cupriavidus taiwanensis in the plant pathogen Ralstonia solanacearum, and selected spontaneous nodulating variants of the chimeric Ralstonia sp. using Mimosa pudica as a trap. Here, we pursued the evolution experiment by submitting two of the rhizobial drafts to serial ex planta–in planta (M. pudica) passages that may mimic alternating of saprophytic and symbiotic lives of rhizobia. Phenotyping 16 cycle-evolved clones showed strong and parallel evolution of several symbiotic traits (i.e., nodulation competitiveness, intracellular infection, and bacteroid persistence). Simultaneously, plant defense reactions decreased within nodules, suggesting that the expression of symbiotic competence requires the capacity to limit plant immunity. Nitrogen fixation was not acquired in the frame of this evolutionarily short experiment, likely due to the still poor persistence of final clones within nodules compared with the reference rhizobium C. taiwanensis. Our results highlight the potential of experimental evolution in improving symbiotic proficiency and for the elucidation of relationship between symbiotic capacities and elicitation of immune responses.

Vespa velutina, also known as the Yellow-legged hornet, is a wasp species native to Asia with a large distribution area in Indonesia. Hyaluronidase B in a wasp venom acts as a "spreading factor", which is the key at the beginning of envenomation. Shameplant (Mimosa pudica), a common plant in Indonesia, has shown the potential to be a hyaluronidase B inhibitor. This study aimed to analyze the potential of secondary metabolites in Shameplant as an inhibitor of V. velutina Hyaluronidase B base on their molecular interactions and as a topical drug base on physicochemical characteristics. In silico computational studies is performed to predict the binding modes of M. pudica compounds and hyaluronidase B enzyme. The secondary metabolites were retrieved from the PubChem database and screened using SwissADME. The seven metabolite compounds were docked with Hyaluronidase B and hyaluronan by HEX Cuda 8.0.0 program. Hyaluronidase B was also docked with its native ligand (hyaluronan) to validate the docking study. Three dimensional and 2D views were then evaluated using Discovery Studio 2016. Results of this study are all compounds do not have the same molecular interaction with the control. It defines no inhibition of the interaction on the active side. Mimopudine is the most potent inhibitor of hyaluronidase B based on its binding energy. While, jasmonic acid is the only compound that meets the physicochemical parameter of the topical drug.

An experiment was conducted at Sher-e-bangla Agricultural University during May to July, 2016 to examine the morpho-physical potentiality of eight green manure species and these species are viz. Sesbania aculeata, Sesbania rostrata, Crotalaria juncea, Vigna unguiculata, Vigna mungo, Vigna radiata, Leucaena leucocephala and Mimosa pudica. Leaves number, biomass production and nodulation are an important character of any green manuring crops as these crops are very potential for increasing soil fertility after incorporation. The growth habits of these species were studied from 15 DAS to 45DAS whereas dry matter/plant and nodulation data were taken from 25 DAS to 50DAS. At 45DAS, Sesbania aculeata, Sesbania rostrata and Vigna unguiculata shown 53% to 149% higher plant height compared to Vigna mungo, although C. juncea performed better at 30DAS compared to V. unguiculata. Again, C. juncea along with S. rostrata and S. aculeata gave the highest fresh biomass (24% to 72%), dry biomass (2.6t/ha to 5.25t/ha), dry matter plant-1 (60% to 83%) and nodulation compared to rest green manures at 45DAS whereas V. unguiculata produced higher dry matter plant-1 at 20DAS but later it declined insignificantly at 50DAS.The lowest performance was observed from V. mungo followed by V. radiata and M. pudica. It was shown that S. rostrata, S. aculeata, C. juncea, V. unguiculata and L.leucocephala performed better regarding biomass, dry matter and nodule production.

<p> Many plants close their leaves in the evening, as if to sleep, and open them early in the morning. Such a circadian rhythm has been known to be controlled by their internal clock. Since Ricca's ingenious experiments suggested that some chemicals play an important role in the leaf-movement of Mimosa pudica, many biologists and chemists have attempted to locate the leaf - closing substances, and a number of compounds have been obtai ned, particularly, by Schildknecht et al. Recently, we were also able to isolate a small amount of a stimulant (activity: ca. 10<sup>8</sup> - 10<sup>·9</sup> M) from the same plant, which consists of three different components (potassium L-malate; magnesium trans-acconitate; dimethylammonium salt). Further extensive study on other nyctinastic plants led to the isolation of a variety of leaf-closing substances. </p> <p> On the other hand, indole-3-acetic acid (IAA) has been reported to be effective for Mimosa pudica as a leaf-opening factor. Three leaf-opening substance named potassium lespedezate, cis-p-coumaroylagmatine, and calcium 4-O-β-D-glucopyranoyl-cis-p-coumarate have been isolated from Lespedeia cuneate G. Don , Albizzia julibrissin D. and Cassia mimosoides, respectively. Based on our experiments using the leaf-opening and -closing substances, the circadian rhythm of these plants must be controlled by their internal clock which regulates a balance of concentration between the leaf-opening and closing substances.</p>

Plants and their derived molecules have been traditionally used to manage numerous pathological complications, including male erectile dysfunction (ED). Mimosa pudica Linn. commonly referred to as the touch-me-not plant, and its extract are important sources of new lead molecules in drug discovery research. The main goal of this study was to predict highly effective molecules from M. pudica Linn. for reaching and maintaining penile erection before and during sexual intercourse through in silico molecular docking and dynamics simulation tools. A total of 28 bioactive molecules were identified from this target plant through public repositories, and their chemical structures were drawn using Chemsketch software. Graph theoretical network principles were applied to identify the ideal target (phosphodiesterase type 5) and rebuild the network to visualize the responsible signaling genes, proteins, and enzymes. The 28 identified bioactive molecules were docked against the phosphodiesterase type 5 (PDE5) enzyme and compared with the standard PDE5 inhibitor (sildenafil). Pharmacokinetics (ADME), toxicity, and several physicochemical properties of bioactive molecules were assessed to confirm their drug-likeness property. Molecular dynamics (MD) simulation modeling was performed to investigate the stability of PDE5–ligand complexes. Four bioactive molecules (Bufadienolide (−12.30 kcal mol−1), Stigmasterol (−11.40 kcal mol−1), Isovitexin (−11.20 kcal mol−1), and Apigetrin (−11.20 kcal mol−1)) showed the top binding affinities with the PDE5 enzyme, much more powerful than the standard PDE5 inhibitor (−9.80 kcal mol−1). The four top binding bioactive molecules were further validated for a stable binding affinity with the PDE5 enzyme and conformation during the MD simulation period as compared to the apoprotein and standard PDE5 inhibitor complexes. Further, the four top binding bioactive molecules demonstrated significant drug-likeness characteristics with lower toxicity profiles. According to the findings, the four top binding molecules may be used as potent and safe PDE5 inhibitors and could potentially be used in the treatment of ED.

Wild Water Buffalo (WWB) Bubalus arnee is an endangered species and a protected animal in Nepal. The remaining WWB population is located in Koshi Tappu Wildlife Reserve (KTWR), and it appears to have low viability under prevailing conditions. We assessed the habitat use and conservation threats to wild water buffalo in KTWR. For habitat analysis the quadrant method was used. Eighty-four quadrants of 25 m2 for trees, 168 quadrants of 10m2 for shrubs and 336 quadrants of 1 m2 for herbs were laid out in the study area. Ivlev’s electivity index (IV) was calculated to assess the use of different habitat components. The important Value Index (IVI) was used for vegetation assessment. A relative threat ranking method was used to assess conservation threats for wild buffalo and their habitats. Wild buffalo mostly preferred habitats with distance to water resources less than 500 m (IV= 0.4), less than 25 % crown coverage (IV= 0.39) and more than 75 % ground coverage (IV= 0.42). The trees species Phyllanthus emblica, Acacia catechu, shrub species Mimosa pudica and the herb species Brachiaria distachya, Vetiveria zizanioides, Imperata cylindrica, and Saccharum spontaneum were preferred by WWB in the study area. Among the different plant categories, we found that Acacia catechu was the most preferred tree species (IVI= 156.95), Mimosa pudica the most preferred shrub species (IVI= 58.68), and Imperata cylindrica the most preferred herb species (IVI= 64.73). Major conservation threats perceived by local stakeholders for wild buffaloes were overgrazing by cattle and genetic swamping through crossbreeding with domestic buffalo. Therefore, conservation of grass species through control of grazing, and prevention of cross breeding are measures supported by this study. Additionally, site-specific conservation strategies should be adopted, based on identified threats in the study area.

Four bacterial strains isolated from root nodules of Phaseolus vulgaris, Mimosa pudica and Indigofera spicata plants grown in the Yunnan province of China were identified as a lineage within the genus Rhizobium according to the analysis of 16S rRNA gene sequences, sharing most similarity with Rhizobium lusitanum P1-7T (99.1 % sequence similarity) and Rhizobium rhizogenes IAM 13570T (99.0 %). These strains also formed a distinctive group from the reference strains for defined species of the genus Rhizobium in a polyphasic approach, including the phylogenetic analyses of the 16S rRNA gene and housekeeping genes (recA, atpD, glnII), DNA–DNA hybridization, BOX-PCR fingerprinting, phenotypic characterization, SDS-PAGE of whole-cell proteins, and cellular fatty acid profiles. All the data obtained in this study suggested that these strains represent a novel species of the genus Rhizobium, for which the name Rhizobium vallis sp. nov. is proposed. The DNA G+C content (mol%) of this species varied between 60.9 and 61.2 (T m). The type strain of R. vallis sp. nov. is CCBAU 65647T ( = LMG 25295T = HAMBI 3073T), which has a DNA G+C content of 60.9 mol% and forms effective nodules on Phaseolus vulgaris.

The legumes (Fabaceae family) are the second most important agricultural crop, both in terms of harvested area and total production. They are an important source of vegetable proteins and oils for human consumption. Non-thermal plasma (NTP) treatment is a new and effective method in surface microbial inactivation and seed stimulation useable in the agricultural and food industries. This review summarizes current information about characteristics of legume seeds and adult plants after NTP treatment in relation to the seed germination and seedling initial growth, surface microbial decontamination, seed wettability and metabolic activity in different plant growth stages. The information about 19 plant species in relation to the NTP treatment is summarized. Some important plant species as soybean (Glycine max), bean (Phaseolus vulgaris), mung bean (Vigna radiata), black gram (V. mungo), pea (Pisum sativum), lentil (Lens culinaris), peanut (Arachis hypogaea), alfalfa (Medicago sativa), and chickpea (Cicer aruetinum) are discussed. Likevise, some less common plant species i.g. blue lupine (Lupinus angustifolius), Egyptian clover (Trifolium alexandrinum), fenugreek (Trigonella foenum-graecum), and mimosa (Mimosa pudica, M. caesalpiniafolia) are mentioned too. Possible promising trends in the use of plasma as a seed pre-packaging technique, a reduction in phytotoxic diseases transmitted by seeds and the effect on reducing dormancy of hard seeds are also pointed out.

This paper explores the status of Invasive Alien Plant Species in an urban forest of Hetauda, Nepal. The study is based on a quadrate survey (130 quadrants) within the transect line at an interval of 30 m within different six habitat types. This study identified a total of 22 invasive alien plant species representing 20 genera and 12 families out of recorded 26 species representing 24 genera and 15 families in the country. This study identified four species namely Chromolaena odorata, Eichhornia crassipes, Lantana camara and Mikania micrantha in the study area that were listed as the world’s 100 worst invasive species. The invasion was found to be negatively correlated with canopy cover. The higher the canopy cover; the lower the abundance of invasive alien species. Regarding the habitat type, settlement area had the highest number of invasive species followed by forest and roadside. Mikania micrantha, Lantana camara, Ageratum houstonianum and Chromolaena odorata were mostly abundant in forest whereas Eichhornia crassipes was highly abundant in wetlands. Mikania micrantha was mostly abundant in settlement area and Senna tora was confined to open land.

Se hizo un inventario de especies de plantas fanerógamas y pteridofitas en potreros en áreas desprovistas de árboles, en la zona del volcán San Martín Tuxtla, en Los Tuxtlas, Veracruz. Con el fin de tener la composición florística más completa posible, se realizaron muestreos durante la temporada seca y la de lluvia del año de 1992, en dos localidades: el ejido Balzapote y la colonia agrícola-ganadera La Palma. En cada localidad se seleccionaron cinco potreros dominados por especies de pastos nativas (conocidos como potreros de grama) y cinco en que prevalece la gramínea introducida Cynodon plectostachyus (llamados potreros de estrella). En cada potrero, dentro de una hectárea se ubicaron al azar 10 cuadros fijos de 2 x 2 m en los que se registró a toda planta presente y se estimó su cobertura, además de medir la altura de la vegetación dentro de cada cuadro. El resultado arrojó un total de 200 especies de angiospermas y 14 de pteridofitas, pertenecientes a 55 familias. Las familias con 10 especies o más fueron Asteraceae, Euphorbiaceae, Poaceae y Leguminosae (sensu lato). Las plantas con cobertura mayor de 10% del área muestreada fueron C. plectostachyus, Axonopus spp., Paspalum conjugatum (Poaceae), Hyptis atrorubens (Lamiaceae) y Mimosa pudica (Leguminosae: Mimosaceae). La mayoría de las especies encontradas en potreros fueron malezas y pastos; sin embargo, también se registraron plántulas de árboles y arbustos.

El estudio fue realizado en la Unidad Productiva "HaciendaLas Mercedes" patrimonio de la Universidad NacionalAgraria (UNA). El objetivo fue contribuir a la conservacióndel Bosque de Galería mediante la aplicación del tratamientosilvicultural de enriquecimiento y repoblación con la especieIguana iguana. La metodología se desarrolló iniciando con unavisita de reconocimiento a La ribera de la Presa Los Sábalos(sitio de la plantación forestal) y a la ribera Presa Las Mercedes(sitio para la repoblación con iguanas). El experimento dede repoblación forestal inició con el establecimiento de seisparcelas con especies forestales (Pithecellobium saman (jacq)Bent, Swietenia humilis Zucc, Guazuma ulmifolia Lam,Calycophyllum candidissimum (Vahl) DC, Albizzia caribeae(Urb).B&R y Dalbergia retusa Hemsl) en un área de 0.22 ha.Dentro de cada parcela se ubicó una parcela útil (16 individuos)para realizar el levantamiento de datos dasométricos (alturacm, diámetro basal mm y sobrevivencia) y análisis estadístico.Luego se identificaron las especies vegetales presentes enla plantación y se monitoreo (caracterización del sitio) deIguana iguana (Iguana verde) y Ctenosaura similis (Garrobonegro también conocida como iguana rayada), para lo cualse establecieron seis transeptos (156 m, 200 m, 209 m, 212m, 190 m y 198 m) en 4.9 ha con la aplicación del métodode King. Posteriormente se estableció la repoblación con laespecie Iguana iguana; para ello se introdujeron 18 hembras y6 machos. Por último se realizo el procesamiento y análisis dela información obtenida. Los mayores incrementos promediostotales y mensuales en altura y diámetro basal se presentaron enC. candidissimum (Vahl) DC (21.93 cm y 3.655 cm y 0.34 mm y0.057 mm). En la sobrevivencia los valores de excelente (100%)lo obtuvieron las especies C. candidissimum (Vahl) DC y D.retusa Hemsl y entre los buenos resultaron G. ulmifolia (76%)y S. humilis (67%). La sobrevivencia promedio de las especiesforestales establecidas fue de (87 %). 10 especies vegetalesfueron identificadas (Elitraria imbricata, Baltimora recta, Sidaacuta, Lantara camara, Rowolfio tetrafila, Commelina difusa,Priva lappulaceae, Mimosa pudica, Datura stramonium ySolanum americanum). En el primer monitoreo no se encontróIguana iguana solo la Ctenosaura similis (52 individuos),observado en los transeptos 2, 4 y 6 (en sitios con árbolesgrandes y frondosos, distantes de la fuente de agua. Despuésde la repoblación, la especie Iguana iguana (51 individuos) seobservó en los transectos 2, 5 y 6 (en sitios próximos a fuentesde agua, árboles pequeños. Y Ctenosaura similis (48 individuos)se observó en los transectos 2, 3, 4 y 6.Palabras clave: Conservación; plantación forestal; cálculosdasométricos; Ctenosaura similis.DOI: 10.5377/calera.v9i12.3
