Full textAbstract:
A number of essential oils are currently in use as aromatherapy agents to relieve anxiety, stress, and depression. Popular anxiolytic oils include lavender (Lavandula angustifolia), rose (Rosa damascena), orange (Citrus sinensis), bergamot (Citrus aurantium), lemon (Citrus limon), sandalwood (Santalum album), clary sage (Salvia sclarea), Roman chamomile (Anthemis nobilis), and rose-scented geranium (Pelargonium spp.). This review discusses the chemical constituents and CNS effects of these aromatherapeutic essential oils, as well as recent studies on additional essential oils with anxiolytic activities.

Full textAbstract:
Four surveys which gathered information from rural communities on useful tree species in Vanuatu have been reviewed and summarized. The surveys were undertaken from 1990 to 1993 and concentrated on species used for fuelwood and local construction. One survey also reported tree species useful for other purposes, such as fruit and nuts, edible foliage and customary uses. There were regional differences in species choices that could be related to the Northern, Central and Southern regions of the country. Popular fuelwood species included Macaranga spp., Hibiscus tiliaceus, Kleinhovia hospita, Dysoxylon spp. and the introduced Leucaena leucocephala. In general, people did not perceive any shortage of fuelwood. There were differences in preferences for fuelwood, depending on whether wood was required for open-fire pot cooking, open-fire roasting, or laplap (a kind of earth oven). Popular species for ground poles included Hibiscus tiliaceus, Flueggia flexuosa, Macaranga spp., Pterocarpus indicus, Bischofia javanica and lntsia bijuga, with some variations in preference between regions. Preferred species for aerial timbers for house construction included Macaranga spp., Flueggia flexuosa, Ficus spp., Kleinhovia hospita and Alphitonia zizyphoides. Species providing commercial timbers, such as Endospermum medullosum, Santalum austro-caledonicum and lntsia bijuga, are valued and are being planted, or wildlings cared for, on-farm. Important fruit and nut trees included Barringtonia edulis, Canarium spp., Syzygium malaccense, Pometia pinnata, lnocarpus fagifer, Burckella obovata and Dracontomelon vitiense. Tree species having multiple importance in customary use, such as Hibiscus tiliaceus, Macaranga spp., lntsia bijuga, Casuarina equisetifolia, Flueggia flexuosa, Kleinhovia hospita, Leucaena leucocephala, Barringtonia edulis and Acacia spp., are ranked highly.

Full textAbstract:
The Australian native edible plant industry is rapidly expanding. We provide a review of the horticultural research that has been carried out on the top 14 commercially significant Australian native edible plants; Acacia spp. Miller (wattle), Acronychia acidula F.Muell. (lemon aspen), Backhousia citriodora F.Muell. (lemon myrtle), Eremocitrus glauca (Lindl.) Burkill (desert lime) and Microcitrus spp. Swingle (native lime), Hibiscus heterophyllus Vent. and Hibiscus sabdariffa L. (rosella), Kunzea pomifera F.Muell. (muntries), Podocarpus elatus R.Br. ex Endl. (Illawarra plum), Prostanthera spp. La Billardiere (native mint), Santalum acuminatum R.Br. (quandong), Solanum centrale Black (bush tomato), Syzygium leuhmannii F.Muell. (riberry), Tasmannia spp. R.Br. (native pepper), Terminalia ferdinandiana (= T. latipes Benth. subsp. psilocarpa Pedley) (kakadu plum) and Tetragonia tetragonioides (Pallas) Kuntze (warrigal greens). The research on most of these species has focused on propagation, breeding, cultivation, nutritional value and the isolation of natural products. On none of the species has research been completed in all these areas, and three species have no research published on them. We describe horticultural research on two other commercial species, Backhousia anisata Vickery (aniseed myrtle) and Davidsonia pruriens F.Muell. var. pruriens and var. jerseyana (Davidson’s plum), and one species with commercial potential, Pringlea antiscorbutica R.Br. ex Hook.f. (kerguelen cabbage). We identify areas that require further research and issues of concern, such as indigenous intellectual property rights and environmental implications.

Full textAbstract:
An inventory to prepare the checklist of angiosperm species in the lateritic hillocks of northern Kerala was conducted in five sampling sites during April 2013–March 2015. In total, we recorded 364 genera with 535 species, of which 334 are native and 201 are non-native. Native species were represented in 102 families, namely, Poaceae (28), Fabaceae (25), Acanthaceae (22), Rubiaceae (17) Euphorbiaceae (14), Commelinaceae (11), Phyllanthaceae (7), etc., whereas, non-native species were represented in 99 families. Among the native species herbs are the predominant habit with 147 species (44%). Out of the 72 endemic species, three taxa namely, Syzygium travancoricum, Santalum album and Hopea ponga are red listed species documented from the study area. Twenty-seven invasive species were also recorded and major threats to the laterite ecosystems are by Lantana camara, Mikania micrantha, Pennisetum polystachyon, Ipomoea spp., and Senna spp. Most part of the laterite has been converted to plantations, building sites and mining sites. The indiscriminate mining for laterite, soil and demolishing the hillocks have severely threatened the very existence of the flora.

Staphylococcus spp. is not only a commensal bacteria but also a major human pathogen that causes a wide range of clinical infections. Recent evidence suggests that Staphylococcus has the ability to colonize the reproductive system and to affect its structure and functions. The objective of this study was to determine the chemical properties and antibacterial effects of select essential oils (EOs): Amyris balsamifera L., Boswellia carterii Birdw., Canarium luzonicum (Blume) A. Gray, Cinnamomum camphora (L.) J. Presl., Cinnamomum camphora var. linaloolifera Y. Fuita, Citrus x aurantium L., Gaultheria procumbens L., Litsea cubeba (Lour.) Pers., Melaleuca ericifolia Smith., Melaleuca leucadendra L., Pogostemon cablin (Blanco) Benth., Citrus limon (L.) Osbeck, Santalum album L., and Vetiveria zizanoides (L.) Roberty against 50 Staphylococcus spp. cultures isolated from human semen, specifically Staphylococcus aureus, S. capiti, S. epidermidis, S. haemoliticus, and S. hominis. The disc diffusion and broth microdilution methods were used to assess the antimicrobial potential and to determine the minimum inhibitory concentration (MIC) of the selected EOs. The best anti-Staphylococcus activities were found with both methods for the essential oils of C. luzonicum (Blume) A. Gray, A. balsamifera, C. camphora, and P. cabli.

Full textAbstract:
AbstractThe Forest Products Commission of Western Australia manages a sandalwood (Santalum spp.) core germplasm collection at Kununurra in the states far north. This collection serves as a significant seed source for sandalwood plantations in the area and remains an important resource for ongoing research. The collection contains S. album trees sourced from Indian arboreta, along with a few trees from West Timor, Indonesia. Also present are representatives of S. macgregorii from Papua New Guinea and S. austrocaledonicum from Vanuatu and/or New Caledonia. Despite the apparently diverse seed origins, the genetic background of many of the accessions remains vague. In this study, diversity and relatedness was assessed by nuclear and chloroplast RFLPs and a phylogeny was inferred. Nuclear RFLPs revealed very low levels of genetic diversity for a tree species, with an observed and expected heterozygosity (Ho and He) of 0.047. Nineteen genotypes were identified within the 233 S. album individuals sampled, with only one tree known to have originated from Timor being differentiated from Indian material. Other trees thought to have come from Timor grouped with those believed to be from India, indicating they were either incorrectly labelled or sourced from heavily modified populations. Despite the poor sample size, chloroplast RFLP analysis revealed no genetic distinction between the Timorese and Indian S. album, which supports the theory of human mediated seed dispersal from Timor to India. The structure of the phylogeny and associated relatedness has assisted in the establishment of seed orchards, designed to ensure maximum diversity is maintained through limiting the proximity of highly related trees. Finally, in light of these and other findings, a hypothesis concerning the evolution of S. album is proposed.

Full textAbstract:
We developed an adaptable, transparent tool that can be used to quantify and compare vulnerability to overharvest for wild collected medicinal plants. Subsequently, we are creating a list of the most threatened medicinal plants in temperate North America. The new tool scores species according to their life history, the effects of harvest, their abundance and range, habitat, and demand. The resulting rankings, based on explicit criteria rather than expert opinion, will make it easier to discuss areas of vulnerability and set conservation priorities. Here we present scores for 40 species assessed using the At-Risk Tool and discuss the traits that led to different scores for six example species: echinacea (Echinacea angustifolia DC. Asteraceae), peyote (Lophophora williamsii (Lem. ex Salm-Dyck) J.M. Coult. Cactaceae), sandalwood (Santalum spp. L. Santalaceae), stinging nettle (Urtica dioica L. Urticaceae), American ginseng (Panax quinquefolius L. Araliaceae) and mayapple (Podophyllum peltatum L. Berberidaceae).

Full textAbstract:
Our understanding of nutrient transfer between host and flowering parasitic plants is usually based mainly on physiological concepts, with little information on haustorial structure related to function. The aim of this paper is to study the haustorial interface and possible pathways of water and solute transfer between a number of host and parasites.Haustorial tissues were fixed in glutaraldehyde and embedded in glycol methacrylate (LM), or fixed in glutaraldehyde then OsO4 and embedded in Spurr’s resin (TEM).Our study shows that lumen to lumen continuity occurs between tracheary elements of a host and four S.W. Australian species of aerial mistletoes (Fig. 1), and some root hemiparasites (Exocarpos spp. and Anthobolus foveolatus) (Fig. 2). On the other hand, haustorial interfaces of the root hemiparasites Olax phyllanthi and Santalum (2 species) are comprised mainly of parenchyma, as opposed to terminating tracheads or vessels, implying that direct solution transfer between partners via vessels or tracheary elements may be limited (Fig. 3).

Full textAbstract:
In 2003 and 2004, a survey of grapevine (Vitis vinifera L.) trunk pathogens was conducted in 30 vineyards in the Western and Northern Cape and Limpopo provinces of South Africa. In each vineyard, 20 visually healthy plants were sampled randomly by removing the distal part of one cordon arm. Isolations were made onto potato dextrose agar (PDA) from the internal wood decay symptoms observed in the cordon samples. Seven Botryosphaeriaceae spp. were identified, including Lasiodiplodia crassispora (1). Other Botryosphaeriaceae spp. are known grapevine trunk pathogens (2). Species identity was confirmed by DNA sequence data of the partial translation factor 1-α gene (1) and sequences deposited in GenBank (GU233658 and GU233659). The L. crassispora isolates (CBS 125626 and 125627) were associated with brown internal necrosis, a known symptom of grapevine Botryosphaeriaceae spp. infection (3), in the cordon arms of Ruby Cabernet grapevines occurring in two vineyards in the Northern Cape Province. L. crassispora was described from cankered wood of Santalum album in Western Australia and endophytically from Eucalyptus urophylla in Venezuela (1). Its grapevine pathogen status was determined using both isolates in a repeated pathogenicity test that included three isolates each of Botryosphaeria dothidea and Neofusicoccum australe as positive controls (2), Trichoderma harzianum as a nonpathogen treatment, and an uncolonized agar plug as a negative control. The Botryosphaeriaceae spp. and T. harzianum were plated on PDA and incubated at 25°C for 7 days. Lignified, 6-month-old shoots of grapevine cv. Chardonnay were excised from grapevines with internodes 4 to 6 used for inoculations. Before wounding, shoots were disinfected by submersion for 1 min in a 1 ml/liter solution of a quaternary ammonium compound (Sporekill; ICA International Chemicals (Pty) Ltd, Stellenbosch, South Africa). Twelve shoots were used for each isolate or control treatment. Wounds were made 2 mm deep on the fifth internode of the shoots with a 5-mm flame-sterilized cork borer (2,3). Wounds were inoculated with a pathogen colonized agar plug (5 mm in diameter) or an uncolonized agar plug and then covered with Parafilm (2,3). Inoculated shoots were incubated in the dark in moist chambers for 14 days at 25°C. After incubation, the bark of the shoots was peeled from the area around the wound and the lengths of any resultant lesions were measured under sterile conditions. The inoculum effect was assessed by analysis of variance and Student's t-test. Results showed that significantly (P < 0.0001) longer lesions were caused by L. crassispora (13.36 mm) compared with N. australe (9.27 mm) and B. dothidea (5.28 mm) and also significantly longer than lesions caused by the nonpathogen and negative controls (3.23 and 2.90 mm, respectively). To determine if lesions were caused by inoculated fungi, isolations were made from the tissue at the edges of the lesions by aseptically removing five 0.5 × 1 mm pieces of wood and placing them on PDA dishes amended with 0.04 g/liter of streptomycin sulfate. Dishes were incubated under normal fluorescent light at 25°C for 14 days before identifying isolated fungi based on morphological and cultural characteristics (1). To our knowledge, this is the first report of L. crassispora as a grapevine pathogen. References: (1) T. I. Burgess et al. Mycologia 98:423, 2006. (2) J. M. van Niekerk et al. Mycologia 96:781, 2004.

Full textAbstract:
The water relations and leaf gas-exchange characteristics of the root hemiparasite quandong (Santalum acuminatum (R.Br.) A.DC) and its neighbouring plants were examined at three field sites in central Southern Australia. This paper examines the role of water potential and osmotic gradients in facilitating the movement of water from host plants to quandong. Quandong exhibited a significantly more negative water potential than the neighbouring plant species at both field sites during summer and winter. A significant proportion of the osmotic potential was accounted for by mannitol, Na + , K + and Cl - . A water potential difference of 1.7 MPa was maintained between quandong and its putative host over a measurement period of 24 h. Xylem sap and leaves of quandong contained considerable concentration (0.1–0.4 mol (kg tissue water) –1 ) of mannitol. Stomatal conductance and assimilation of quandong were lower than those of the neighbouring plants at both Middleback and Aldinga during both summer and winter measurements. Measurements of transpiration for quandong differed between the two sites. The lower transpirational water loss resulted in quandong at Middleback having an instantaneous water-use efficiency higher (0.13–2.2 µmol (CO 2 ) mmol –1 (H 2 O)) than the neighbouring plants. Daily sap flow and calculated hydraulic conductivity were not significantly different between quandong and putative host plant.

A arborização urbana é entendida como toda cobertura de vegetação arbórea presente nas cidades, a mesma é uma grande influenciadora na qualidade de vida da população. Porém é necessário um bom planejamento e monitoramento das espécies inseridas no ambiente urbano, de modo que se tenha os benefícios esperados da arborização. O objetivo do trabalho foi identificar as implicações da utilização do Ficus spp. em 4 bairros e 11 praças do município de Santarém, Pará. Foi realizado um inventário total destas áreas, considerando somente os indivíduos com altura igual ou superior a 1,5m. Considerou-se uma espécie exótica por não ser de formação originária do Brasil. Foram calculadas a Frequência absoluta (FA) e Frequência relativa (FR) da espécie Ficus spp. em relação ao número total de indivíduos inventariados. Para esse estudo foram totalizados 1416 indivíduos, dentre eles, 115 são Ficus spp. no momento do levantamento, 93,91% dos indivíduos arbóreos estavam em estado vegetativo. Em relação a sanidade da copa das espécimes encontradas, 79,13% possui copa saudável e sem problemas. Dentre as árvores amostradas, aproximadamente 25% da amostra necessita de algum tipo de manejo, seja poda, substituição ou remoção da árvore. Essa espécie exótica não é indicada para arborização urbana, pois tem causado conflitos com calçadas, tubulações e rede elétrica, devido terem raízes agressivas e crescimento rápido.

Full textAbstract:
Lauraceae families have great diversity in the world’s tropical regions and are represented mainly by aromatic shrubs and trees with significant production of essential oils (EOs). This work presents a review of the EO chemical profiles from specimens of Aniba, including their seasonal variations, geographical distributions, and biological activities in the Amazon biome. Based on the survey, 15 species were reviewed, representing 167 oil samples extracted from leaves, twig barks, and woods. Brazilian Amazon was the most representative geographic area in the number of specimens, highlighting the locations Belém, (Pará state, PA) (3 spp., 37 samples), Santarém (PA) (3 spp., 10 samples), Carajás (PA) (3 spp., 7 samples), and Manaus (Amazonas state, AM) (3 spp., 16 samples). The main compound classes identified in oils were benzenoids and phenylpropanoids, represented by 1-nitro-2-phenylethane, benzyl salicylate, benzyl benzoate and methyleugenol, along with terpenoids, especially monoterpenes and sesquiterpenes, such as linalool, α-phellandrene, β-phellandrene, β-selinene, and spathulenol. The EOs from Aniba showed considerable variation in the chemical profiles according to season and collection site. The hierarchical cluster analysis classified the samples into two main groups according to chemical composition. This review highlights its comprehensive and up-to-date information on history, conservation, traditional uses, chemosystematics, pharmacological potential of Aniba species.

Full textAbstract:
Canine ehrlichiosis and babesiosis are the most prevalent tick-borne diseases in Brazilian dogs. Few studies have focused attention in surveying tick-borne diseases in the Brazilian Amazon region. A total of 129 blood samples were collected from dogs living in the Brazilian eastern Amazon. Seventy-two samples from dogs from rural areas of 19 municipalities and 57 samples from urban stray dogs from Santarém municipality were collected. Serum samples were submitted to Indirect Immunofluorescence Assay (IFA) with antigens ofBabesia canis vogeli, Ehrlichia canis, and six Rickettsia species. The frequency of dogs containing anti-B. canis vogeli, anti-E. canis, and anti-Rickettsia spp. antibodies was 42.6%, 16.2%, and 31.7%, respectively. Anti-B. canis vogeli antibodies were detected in 59.6% of the urban dogs, and in 29.1% of the rural dogs (P < 0.05). For E. canis, seroprevalence was similar among urban (15.7%) and rural (16.6%) dogs. ForRickettsia spp., rural dogs presented significantly higher (P < 0.05) prevalence (40.3%) than urban animals (21.1%). This first study on tick-borne pathogens in dogs from the Brazilian eastern Amazon indicates that dogs are exposed to several agents, such asBabesia organisms, mostly in the urban area; Spotted Fever group Rickettsia organisms, mostly in the rural area; andEhrlichia organisms, in dogs from both areas studied.

Full textAbstract:
The objective of this 3-year study was to investigate the relationships between soil salinity and ecophysiological responses of C3 and C4 native plant species around Lake Altham and Lake Coyrecup (both are salt lakes in Western Australia), and to evaluate their potential for use in the remediation of salt-affected soils. Three shrubs (Atriplex vesicaria, Tecticornia lepidosperma and T. indica) that grew in highly saline soil of average Na concentration greater than 300 mM had higher leaf δ13C and δ15N ratios. These species also had higher Na-to-K and Na-to-Ca ratios in both their leaves and stem xylem sap, indicating that these species accumulate high amounts of sodium in their tissues. In contrast, tree species Eucalyptus loxophleba, Casuarina obesa and Acacia acuminata grew in soil of average Na concentration of less than 100 mM and had lower values of δ15N, δ13C, Na content, and Na-to-K ratio in their leaves. These species also had lower xylem Na-to-K and Na-to-Ca ratios. Seasonal effects were observed in leaf total N content, leaf Na, xylem sap Na-to-K ratio and xylem sap Na-to-Ca ratio. Strong and significant positive correlations (r > 0.75; P < 0.01) were observed between soil Na concentration and ecophysiological responses, such as leaf Na contents, leaf δ15N, xylem sap Na, xylem Na-to-K ratio and xylem Na-to-Ca ratio. Overall, Atr. vesicaria, T. lepidosperma, T. indica and Santalum acuminatum are good candidates for remediation of highly saline soils.

As espécies vegetais fibrosas ocupam papel de destaque no cotidiano das comunidades tradicionais amazônicas ao lado das espécies medicinais, alimentícias e madeireiras. Na microrregião do Salgado do estado do Pará - constituída pelos municípios de Colares, Curuçá, Magalhães Barata, Maracanã, Marapanim, Salinópolis, Santarém Novo, São Caetano de Odivelas, São João de Pirabas e Vigia - as fibras vegetais são usadas em cestaria, trançados, fixadoras em substituição ao prego, adornos e vestuário. Para a elaboração do presente trabalho, os dados foram obtidos entre artesãos e pescadores artesanais da microrregião do Salgado do estado do Pará, com cerca de 150 entrevistas semiestruturadas. Foram registradas 17 espécies, distribuídas em oito famílias e 17 gêneros utilizados na preparação de implementos de pesca artesanal, cujas matérias prima são provenientes de diversas partes da planta, onde as talas são da haste caulinar de Marantaceae e estipe de Arecaceae, os cipós são raízes de Araceae e Cyclanthaceae e os caules de Bignoniaceae e Dilleniaceae, enquanto que as palhas são folhas e pinas de Arecaceae. A família mais representativa com relação ao número de espécies e o fornecimento de matéria prima utilizada foi Arecaceae com 8 spp., seguida de Dilleniaceae e Araceae com 2 spp., Bignoniaceae, Bombacaceae, Cyclanthaceae, Marantaceae e Poaceae com 1 sp. cada. O trabalho visa contribuir para o conhecimento das espécies vegetais fibrosas, quanto a sua morfologia, origem e manuseio da matéria prima, os produtos confeccionados e seus usos, além do registro dos aspectos culturais da utilização de espécies vegetais fibrosas no cotidiano da atividade pesqueira artesanal daquela microrregião.

<p class="Textodecomentrio1">La tortuga amazónica <em>Podocnemis expansa</em> Schweigger, 1812 es un recurso muy importante para las poblaciones ribereñas de fauna de la región amazónica, además de ser una de las principales especies enumeradas para la producción en cautiverio. El consumo de esta especie como alimento en la región ha generado una demanda de estudios sobre salud animal y sus posibles impactos en la salud pública. El objetivo principal de este estudio fue evaluar la microbiota gastrointestinal de las tortugas amazónicas en cautiverio y vida libre, y la influencia del hábitat en la composición de la flora. Un total de 116 tortugas adultas, de ambos sexos fueron elegidas, y 51 fueron capturados en la isla de São Miguel, Santarém (PA), 50 animales en cautiverio para comercio y 15 provenían de un criadero de reproducción para la conservación, que se encuentra en la región metropolitana de Belém. De cada animal se recogió material biológico de la cloaca y se envió al laboratorio de la Universidad Federal de Pará, Brazil. De 116 muestras se obtuvieron 245 aislamientos bacterianos en el que 83 (33.87 %) eran de animales de vida libre, y 162 (65.72 %) de cautiverio. Especies de <em>Klebsiella pneumoniae</em> fueron los aislamientos más frecuentes de las 52 muestras, 21.22 % del crecimiento total de bacterias, seguido de <em>Enterobacter cloacae</em> 29 %, (35/14), <em>Serratia marcescens </em>84 % (11/29) y <em>Salmonella </em>spp. 80 % (24/9). En las tortugas de vida libre, los microorganismos aislados corresponden a los géneros: <em>Enterobacter, Klebsiella, Citrobacter </em>y<em> Aeromonas. Klebsiella pneumoniae, S. marcescens, E. cloacae </em>y <em>Salmonella </em>spp. presentaron frecuencias altas en animales de cautiverio. Este resultado muestra una mayor diversidad de microorganismos en animales de vida libre y muestras con alta contaminación en animales de cautiverio<strong>.</strong> Las especies de <em>Salmonella </em>spp., <em>E. coli </em>y<em> Acinetobacter </em>spp., pueden ser sugeridas como indicadores de la calidad sanitaria de las poblaciones de la tortuga amazónica. Sin embargo el estudio reveló que el hábitat influyó en la composición de la flora gastrointestinal de las tortugas. El conocimiento de la flora gastrointestinal de los animales es de suma importancia en la identificación de los agentes patógenos presentes en la fauna nativa de la región amazónica.</p>

Full textAbstract:
This study evaluated the seasonality of Sphingidae spp. in two areas of savannah, in the eastern Brazilian Amazon, sampled for one year (June, 2014 through May, 2015) with the aid of Pennsylvania light traps placed at four sampling points. Data on fauna were obtained through the following parameters: abundance (N), richness (S), composition, Shannon diversity and uniformity indices (H’ and U’), and the Berger-Parker (BP) dominance index. Richness estimates were calculated using Bootstrap, Chao1, ACE, Jackknife 1, and Jackknife2 estimators. The Pearson correlation was also used to analyze the effect of climatic variables such as rainfall, temperature, and relative humidity on richness and abundance. The result for the parameters analyzed during the entire sampling period was N= 374, S= 34, H’= 2.59, U= 0.733 and BP= 0.235. The estimation of richness showed that between 63% and 87% of expected species were collected (Bootstrap estimated 39 species and Chao1 estimated 54). The most representative species were: Isognathus caricae (Linnaeus, 1758) (N= 88), Enyo lugubris lugubris (Linnaeus, 1771) (N= 58), Isognathus menechus (Boisduval, [1875]) (N= 46) and Cocytius duponchel (Poey, 1832) (N= 44), with 54% of the sample containing species considered rare divided into 298 male and 76 female specimens. For climatic variables, there was a moderate positive correlation only between abundance and temperature. The less-rainy period presented greater richness (S= 26) and abundance (N= 222), and the rainy period had better indices for H’ (2.55), U (8.01), and BP (0.230). The richness estimator Jackknife 2 was the best estimator in both sampling periods with 34 in the less-rainy period and 45 in the rainy period. The richness and abundance obtained in this study contribute significantly to the knowledge of Sphingidae fauna in an area of Amazonian savannahs.

Abstract Background: African American (AA) women are less likely to develop breast cancer but when they do, their mortality rates are 40% higher compared to Non-Hispanic White (NHW) women. This disparity is particularly striking among ER+ breast cancer cases. The purpose of this study is to examine whether there are racial differences in metabolic and molecular pathways typically activated in patients with ER+ positive breast cancer. Methods: We collected plasma from AA and NHW cases and controls to conduct an untargeted metabolomics analysis using gas chromatography-mass spectrometry (GC-MS) to identify metabolites that are possibly altered in the different race groups. Statistical methods combined with multiple feature selection and prediction models were employed to identify race-specific altered metabolic signatures. This was followed by the identification of altered metabolic pathways with a focus on AA patients with breast cancer. The clinical significance of the findings was further examined in the PanCancer Atlas breast cancer data set. Results: We identified differential metabolic signatures between NHW and AA patients. In AA patients, we observed disturbed amino acid metabolism, while fatty acid metabolism was significant in NHW patients. By mapping these metabolites to genes, this study identified significant relations with regulators of metabolism such as methionine adenosyltransferase 1A (MAT1A), DNA Methyltransferases, Histone methyltransferases for AA individuals, and Fatty acid Synthase (FASN) and Monoacylglycerol lipase (MGL) for NHW individuals. Specific histone methyltransferase NELFE was overexpressed and associated with poor survival exclusively in AA individuals. Conclusion: We employ a comprehensive and novel approach that integrates multiple machine learning methods, and statistical methods, coupled with human functional pathway analyses. This metabolic profile of serum samples might be used to assess risk progression in AA individuals with ER+ breast cancer. To our knowledge, this is a novel finding that describes metabolic alterations in AA breast cancer and emphasizes a potential biological basis for breast cancer health disparities.

Blood 120, no. 21 (November 16, 2012): 3895. http://dx.doi.org/10.1182/blood.v120.21.3895.3895.
Full textAbstract:
Abstract Abstract 3895 Background Unique miRNA expression signature is associated with CLL prognostic factors and disease progression (Calin et al., 2005; Mraz et al., 2009), and thus contributes to CLL pathogenesis. The mechanism through which miRNA expression is deregulated in cancer, including CLL, is not well characterized. However, the presence of mutations and single nucleotide polymorphisms (SNPs) in miRNA genes has been described (Calin et al., 2005; Ryan et al., 2010). Nevertheless, the impact and frequency of such variations in CLL patients have yet to be elucidated. Aim We searched for sequence variations in 109 pre-miRNAs with possible role in CLL pathogenesis. Additionally, we studied the effect of variations detected in miR-29b/29c genes on their expression in more details. Methods A custom resequencing microarray (Affymetrix) contained probes for 109 pre-miRNAs incl. ∼20 nt from 5′ and 3′ ends of pri-miRNA. MiRNAs were amplified by long range PCR from genomic DNA isolated from peripheral blood cells of 98 high-risk CLL patients (81.6 % unmut IgHV; 37.8 % mut TP53). Amplicons were pooled, fragmented and co-hybridized on the array according to the manufacturer's protocol. The presence of variations detected by microarray was confirmed by Sanger sequencing. The germline/somatic origin of novel variations was performed by direct sequencing of DNA isolated from buccal swabs of the patient carrying the variation. Pri-miR-29c and pri-miR-29b-2 were analysed by Sanger sequencing in additional cohort of 213 CLL patients. The effect of variations detected in miR-29 on their expression was studied by Real-Time PCR (TaqMan miRNA Assays, ABI) in 107 CLL patients. RNAfold tool was used to study the effect of variations on miR secondary structures. To see the difference between allelic frequencies of SNPs detected in miRNAs in CLL patients and healthy population, data from the 1000 genomes project (n=1092 samples) were used. Results Within 98 CLL patients, resequencing microarrays detected 18 annotated SNPs (NCBI dbSNP Build 134, 135) in 15 miRNAs, and importantly, 5 novel variations in 5 miRNAs (pri-miR-29a, pre-miR-16–1, pre-miR-372, pre-miR-106b, mature miR-142–3p). To see whether the novel variation in pre-miR-16–1 is a true mutation or a very rare SNP, 193 CLL patients (105 pts. with del13q) were further analysed. Surprisingly, neither novel variation detected by microarray nor known mutation in pri-miR-16–1 previously detected in two CLL patients (Calin et al., 2005), were found. MiR-29 family, which is directly implied in CLL pathogenesis (Pekarsky et al., 2006; Santanam et al., 2010), has been analysed in more details. In the studied cohort of 213 CLL patients, 7 SNPs and one novel variation were found in pri-miR-29b-2 and two SNPs were found in pri-miR-29c. As shown by RNAfold, miR secondary structure was affected by 14 variations in total, suggesting their possible subsequent relevance for miR stability and processing. Moreover, the insertion in pri-miR-29b lowered its expression (fold change 0.7), but only in patients with unmut IgHV (p=0.036). All detected variations were of germline origin except for miR-655, whose mutation was present only in one B-cell subclone in a biclonal CLL case. The allelic frequency of miR-SNPs differed significantly in 8/62 SNPs (p<0.05). Interestingly, 5 out of these 8 SNPs, incl. the insertion in miR-29b-2, were statistically significantly more frequent in analysed CLL patients. Conclusion We herein confirm that both SNPs and new sequence variations, most of which were present outside mature miRNAs, are frequent in CLL patients. We also show that miR-16 variations are extremely rare (<0.5%) in CLL, which is in contrast to previously published data (Calin et al., 2005). On the contrary, some miR-SNPs, including the insertion in miR-29b, are more frequent in CLL patients than in healthy population. This suggests that not only mutations but also SNPs may be related to CLL pathogenesis; however, larger population studies of different cohorts are needed to verify their association and possible impact on CLL biology.

Coronavirus disease (COVID-19) is an acute infectious disease caused by infection with a novel coronavirus SARSCoV-2. The disease severity can range from mild to developing into critical with pneumonia and even life-threatening complications such as Acute Respiratory Distress Syndrome (ARDS), shock, or multi-organ system dysfunction. The clinical picture of Nazla-e-Wabaiya is almost similar to that of Covid-19 like body ache, sore throat, nasal irritation, burning sensation in eyes sneezing, cough, and fever. As per the Unani scholars, the prophylaxis and management include various single and compound drugs to be used orally. They also prescribed various drugs as disinfectants to be used for fumigation, incense, and spray. Ibn Sina advised that houses should be sanitized daily by spraying Arq Gulab (Rosa damascene), Arq Bed Sada (Salix caprea), or Arq Nilofer (Nymphaea alba) and recommended Bukhoor (incense) of Sa'ad Kufi (Cyperusrotundus), Habb-ul-Aas (Myrtuscommunis), Kundur (Boswelliaserrata), and Sandalwood (Santalum spp.). For the treatment of Nazla-e-Wabaiya, the decoction (Joshanda) of Unnab, Sapistan, and Behidana along with Sharbat Banafsha have been recommended by many eminent Unani scholars. They have also recommended using various types of Khamiras like Khamira Gaozaban, Khamira Abresham SheeraUnnabWala, Khamira Marwareed to improve general health and immunity.

Esta pesquisa objetivou identificar através de análises sensoriais, microbiológicas e químicas fatores que oferecessem variação sobre o tempo de vida útil no processo de armazenagem em camadas de gelo do Mapará (Hypophtalmus spp.).Foram realizadas duas amostras na Feira Mercado do Pescado em Santarém-PA: a amostra A, experimento 1, com n=143 e a amostra B, experimento 2, com n=8. Foram retirados dois peixes para as análises sensoriais, dois para avaliação do pH, um para prova de amônia, um para o teste de Éber de H2S e um para análise microbiológica.As análises sensorias foram realizadas por painelistas, utilizando dois peixes para cada repetição. A determinação do pH,teste da amônia e a reação do gás sulfídrico foi realizada no tempo zero e a cada quatro, três e dois dias, segundo as normas analíticas do Instituto Adolfo Lutz. O teste da amônia e a reação do gás sulfídrico foi realizado utilizando-se a prova de Éber. As análises microbiológicas também foram realizadas no mesmo intervalo de dias, com testes de colimetria, detectando presença/ausência de bactérias.Os resultados obtidos na análise sensorial, indicaram que o ponto de rejeição do pescado ocorreu entre o 17º e 20º dia.Os dois experimentos apresentaram valores de pH superior a 7 na carne estando fora do limite estabelecido por lei. Na prova de Éber para H2S, houve resultados positivos a partir do 11º dia. O teste de Éber para amônia, apresentou valor positivo a partir do 14º dia. Na análise microbiológica, foram encontrados valores de NMP/gde <1,8 a 79x104 (NMP/g) para coliformes termotolerantes e de 11 a >1.600 (NMP/g) de coliformes totais. O resultado permitiu inferir que as características organolépticas não conferem qualidade. Recomenda-se monitoramento, pesquisa e conscientização contínua acerca das boas práticas de pesca e manejo do pescado pós captura, melhoria nos estabelecimentos de comercialização de peixe e na cadeia do frio, a fim de garantir um pescado de qualidade para o consumidor.
