Abstract:

Twelve polyphenols from three distinct families (dihydroflavonols, flavan-3-ols, and flavanones) were studied as potential substrates of anthocyanidin synthase from Vitis vinifera (VvANS). Only flavan-3-ols of (2R,3S) configuration having either a catechol or gallol group on ring B are accepted as substrates. Only dihydroflavonols of (2R,3R) configuration are accepted as substrates, but a catechol or gallol group is not mandatory. Flavanones are not substrates of VvANS. HPLC and MS/MS analyses of the enzymatic products showed that the VvANS-catalyzed oxidative transformation of (+)-dihydroflavonols, such as dihydroquercetin, dihydrokaempferol and dihydromyricetin, leads only to the corresponding flavonols. Among the flavan-3-ols recognized as substrates, (+)-gallocatechin was only transformed into delphinidin by VvANS, whereas (+)-catechin was transformed into three products, including two major products that were an ascorbate–cyanidin adduct and a dimer of oxidized catechin, and a minor product that was cyanidin. Data from real-time MS monitoring of the enzymatic transformation of (+)-catechin suggest that its products are all derived from the initial C3-hydroxylation intermediate, i.e., a 3,3-gem-diol, and their most likely formation mechanism is discussed.

Abstract:

Tyrosinase is generally known as a melanin-forming enzyme, facilitating monooxygenation of phenols, oxidation of catechols into quinones, and finally generating biological melanin. As a homologous form of tyrosinase in plants, plant polyphenol oxidases perform the same oxidation reactions specifically toward plant polyphenols. Recent studies reported synthetic strategies for large scale preparation of hydroxylated plant polyphenols, using bacterial tyrosinases rather than plant polyphenol oxidase or other monooxygenases, by leveraging its robust monophenolase activity and broad substrate specificity. Herein, we report a novel synthesis of functional plant polyphenols, especially quercetin and myricetin from kaempferol, using screened bacterial tyrosinases. The critical bottleneck of the biocatalysis was identified as instability of the catechol and gallol under neutral and basic conditions. To overcome such instability of the products, the tyrosinase reaction proceeded under acidic conditions. Under mild acidic conditions supplemented with reducing agents, a bacterial tyrosinase from Bacillus megaterium (BmTy) displayed efficient consecutive two-step monophenolase activities producing quercetin and myricetin from kaempferol. Furthermore, the broad substrate specificity of BmTy toward diverse polyphenols enabled us to achieve the first biosynthesis of tricetin and 3′-hydroxyeriodictyol from apigenin and naringenin, respectively. These results suggest that microbial tyrosinase is a useful biocatalyst to prepare plant polyphenolic catechols and gallols with high productivity, which were hardly achieved by using other monooxygenases such as cytochrome P450s.

Abstract:

For recently devised wound-healing materials, a variety of acute application systems with sustainable therapeutic effects on wound sites have been suggested. For example, hydrogel-type healing agents with porous structures and high drug encapsulation efficiencies have been developed for wound repair. However, challenges remain about the poor mechanical and adhesive properties of hydrogels. Herein, we propose a punicalagin (PC)-containing wound-healing hydrogel in adhesive form that is mechanically stable and has sustainable wound-healing therapeutic efficiency. The APC hydrogel, composed of alginate (ALG), PC, and chitosan–gallol (CHI–G), exhibits significant mechanical and self-healing properties, thus indicating that PC increases cross-linking in ALG/CHI–G as macromolecule. The PC-containing mechanically enhanced hydrogel demonstrates high tissue adhesiveness. Sustainable PC release for 192 h, which indicates high therapeutic effect of the released PC, and great blood compatibility are evaluated based on rapid blood coagulation and minimal hemolysis. The cytocompatibility and wound-healing abilities of the PC-containing APC hydrogel are greater than those of the non-PC hydrogel, as verified by cell compatibility and wound scratch assays. These results indicate that a suitable concentration of PC-containing hydrogel with sustainable moisture condition and PC release may inspire further polyphenol-agent-containing hydrogels as wound-healing agents with structural stability and therapeutic efficiency.

Abstract:

Since the first introduction of a synthetic polyphenol called polydopamine, both it and its derivatives have received significant attention from material scientists owing to their unique functionality. In particular, synthetic polyphenols have been utilized as interfacial engineering tools; many important review papers have been published regarding this topic. However, despite those that have focused on the applicability of synthetic polyphenols, fundamental aspects of crosslinking mechanisms and resultant characteristics have still been overlooked in the community. This review covers the mechanisms for building synthetic polyphenols, which are dependent on the number of hydroxyl groups of each phenolic building block. The inherent physicochemical properties of the developed polyphenolic materials are discussed in depth herein. This review can provide guidelines for selecting appropriate phenolic building blocks when designing relevant polyphenolic biomaterials.

Abstract:

The reactivity of two phenolic porphyrins bearing respectively catechol and gallol-derived meso substituents (5,10,15,20-tetrakis(3,4-dihydroxyphenyl)porphyrin and 5,10,15,20-tetrakis(3,4,5-trihydroxyphenyl)porphyrin) with trivalent metallic ions (Fe, Mn, In) was studied. Six supramolecular compounds were obtained and structurally characterized by single crystal X-ray diffraction. In each compound, the supramolecular assembly was based on the axial coordination of a phenolate function to the metallic ion lying in the porphyrinic core. A great diversity of supramolecular architectures was accessible through such simple arrangements, and objects ranging from dimers to one-dimensional polymers were isolated. Some of these assemblies were further investigated in solution by mass spectrometry and by UV-vis absorption spectroscopy. For the iron-based materials, the redox behavior was studied in solution through cyclic voltammetry experiments in inert conditions and under air.

Abstract:

Enzymes/Nanoparticles (NPs) bioconjugates are massively used nowadays to develop thin films for optical and electrochemical biosensors. Nevertheless, their full characterization as a thin coating onto electrodes remains little discussed, in particular the influence of NPs size and enzyme/NPs ratio used in the electrodeposition solution. In this study, GOx (160 kDa) and HRP (44 kDa) were used in association with tannic acid capped gold NPs (a series with sizes from 7 to 40 nm) to electrodeposit biosensor coatings, sensitive towards glucose and H2O2, respectively. The electrodeposition process was based on a mussel-inspired electro-crosslinking between gallol moieties of tannic acid (at the surface of NPs) and amine moieties of the enzymes. On one hand, the sensitivity of the GOx/NPs coatings depends strongly on the NP size and the enzyme/NPs molar ratio of the electrodeposition solution. An optimal sensitivity was obtained by electrodeposition of 11 nm NPs at a GOx/NPs molar ratio close to the theoretical value of the enzyme monolayer. On the other hand, a modest influence of the NPs size was found on the sensitivity in the case of the electrodeposited HRP/NPs coatings, reaching a plateau at the HRP/NPs molar ratio close to the value of the theoretical enzyme monolayer. In both cases, the enzyme/NPs molar ratio played a role in the sensitivity. To fully understand the parameters driving the biosensor sensitivity, a comprehensive evaluation of the colloidal state of the bioconjugates is proposed here.

Abstract:

Las concentraciones de metales pesados en aves están influenciadas por factores como dieta, migración y tiempo de residencia. En el presente estudio se midieron las concentraciones (en μg∙g-1 de peso seco) de los metales pesados cadmio (Cd), níquel (Ni), cobre (Cu), plomo (Pb), cromo (Cr) y zinc (Zn) en sangre de gallo (Gallus gallus domesticus). Para ello se le extrajeron 2 ml de sangre a ocho adultos y siete juveniles, y luego se procesaron con técnicas rutinarias de digestión, vertiendo 0,5 g de sangre en tubos de digestión con 5 ml de una mezcla ácida (180 ml de ácido nítrico y 100 ml de ácido clorhídrico), para lo cual se usó un bloque de calentamiento. Se analizaron en un espectrofotómetro de absorción atómica con flujo de aire-acetileno y corrector de fondo de deuterio. Las concentraciones promedio de metales pesados determinados en la sangre de los gallos adultos y juveniles no mostraron diferencias estadísticamente significativas, pero se pudo evidenciar que el patrón de las concentraciones se distribuyó de distinta manera en cada grupo. En orden descendente: Zn > Ni > Pb > Cu > Cr > Cd, en adultos; mientras que para los juveniles fue: Zn > Pb > Ni > Cu > Cr > Cd. Las concentraciones promedio para cada uno de los metales pesados analizados obtenidos en sangre de gallo fueron similares o estuvieron por debajo de los límites permisibles a los señalados en estudios realizados en otros países. En general, las concentraciones de los metales pesados obtenidos en los gallos no se consideran alarmantes.

Este estudio investigó el rendimiento del crecimiento y el perfil sanguíneo de 240 gallos jóvenes expuestos a diferentes niveles de champiñón ostra (Pleurotus ostreatus Jacq ex fr.) en agua y piensos durante 12 semanas. Las aves fueron criadas durante 3 semanas y posteriormente subdivididas en ocho grupos de tratamiento siguiendo un diseño experimental factorial de 2 x 4 consistente en 2 vías de administración (agua y piensos) cada una a 4 niveles de inclusión (0, 5, 10 y 15 ml/litro de agua y 0 , 500, 750 y 1000 ppm, respectivamente). Cada tratamiento contenía 30 aves con tres repeticiones de 10 aves cada una. Los datos obtenidos fueron sometidos a un diseño completamente aleatorio. Las aves en 1000 ppm y 15 ml de niveles de inclusión de champiñones ostra en pienso y agua, respectivamente, tuvieron el mayor peso final (P < 0.05) y aumento de peso, y las mejores proporciones de conversión de alimento de 3,16 y 3,19, respectivamente. El PCV, HB, RBC, la proteína total y la globulina de los gallos jóvenes resultaron los más altos (P < 0.05) en la inclusión champiñón de ostra en 10 ml en un litro de agua. El colesterol total, los triglicéridos, el LDL y el VLDL fueron los más bajos (P < 0.05) en los gallos jóvenes a la inclusión de 1000 ppm de champiñón ostra en la alimentación. Los gallos jóvenes, tras la inclusión de 15 ml y 750 ppm de champiñón ostra en agua y en alimentación, respectivamente registraron el HDL más alto (49,50 mg/dL). Se concluyó que la administración de champiñones ostra en agua y piensos a 15 ml/litro y 750 ppm, respectivamente, podría adoptarse en la producción de pollos de gallo para mejorar el rendimiento del crecimiento y el perfil sanguíneo.

Abstract:

Mango seed kernel extracts (MSKE) from Kaew and Choke-Anan mango cultivars were fractionated using Sephadex LH-20 column chromatography. Antioxidant activity and the inhibitory effects on tyrosinase, 5-lipoxygenase, hyaluronidase and α-glucosidase of MSKE fractions were evaluated. The key components of polyphenol, found in the most active fraction, were identified using LC-ESI-MS. Three major isolates were obtained from both cultivars of the MSKE with the absorbance being higher for Choke-Anan than Kaew. Fraction 3 of MSKE from both cultivars showed significantly (P ≤ 0.05) higher antioxidant activity and 5-lipoxygenase, hyaluronidase and α-glucosidase inhibitory activity with Choke-Anan more effective than Kaew. Six different polyphenols were found in fraction 3 of both cultivars. These were tri-o-galloyl-glucoside, tetra-o-galloyl-glucoside, maclurin tri-o-galloyl-glucoside, penta-o-galloyl-glucoside, hexa-o-galloyl-glucoside, and hepta-o-galloyl-glucoside. In the MSKE from Choke-Anan, hexa-o-galloyl-glucoside, and tetra-o-galloyl-glucoside were the two major components, whereas in the MSKE from Kaew tetra-o-galloyl-glucoside was the only major component. The results indicate that MSKE is a suitable by-product that could be utilised for adding value to the mango processing industry and could represent a valuable input into functional foods and pharmaceutical production.

Abstract:

AbstractS3 is a low-pitched sound (25–50Hz) which is heard in early diastole, following the second heart sound. The following synonyms are used for it: ventricular gallop, early diastolic gallop, protodiastolic gallop, and ventricular early filling sound. The term “gallop” was first used in 1847 by Jean Baptiste Bouillaud to describe the cadence of the three heart sounds occurring in rapid succession. The best description of a third heart sound was provided by Pierre Carl Potain who described an added sound which, in addition to the two normal sounds, is heard like a bruit completing the triple rhythm of the heart (bruit de gallop). The following synonyms are used for the fourth heart sound (S4): atrial gallop and presystolic gallop. S4 is a low-pitched sound (20–30 Hz) heard in presystole, i.e., shortly before the first heart sound. This produces a rhythm classically compared with the cadence of the word “Tennessee.” One can also use the phrase “A-stiff-wall” to help with the cadence (a S4, stiff S1, wall S2) of the S4 sound.

In two experiments, we tested pictures of horse gaits—alt (standing), walk, trot, gallop, and a fake gallop, a pose shown in a well-known Gericault painting. The pose was portrayed frequently in the nineteenth century, its features hotly debated. Fake gallop has legs extended fore and rear, close to parallel to the ground. Experiment 1 sampled real artworks depicting horses and Experiment 2 used silhouettes of horses. In both, reports of amount of movement increased from alt to fake gallop. In Experiment 1 similar results were obtained from novices and equestrians (‘experts’ familiar with horses). The extreme leg extension in fake gallop may suggest high speed, as Arnheim suggested. However, true gallop includes legs curled close together under the body—a ‘running pony’ pose—so both extremes of extension may suggest high speed. In Experiment 2, novices judged fake gallop unrealistic despite giving high movement scores. We suggest its depiction may be metaphoric, meaning a deliberately false item has relevant features of a referent. For the artworks, the amount of movement reported correlated positively but quite modestly with aesthetic appreciation, but for the silhouettes, the correlation was reversed. We suggest expression can be positive for many horse poses.

Abstract:

Everyone knows the name Ernest Gallo. With his brother Julio they started the E&J Gallo Winery in Modesto, California in 1932. In 70 years the winery grew to be the largest in the world. Some evidence of the scale of the Gallo Winery's operations can be found in the interview itself.“We will crush this year [1971] somewhere around 650,000 tons of grapes. We will produce only somewhere in the area of 50,000 tons” (Gallo, 1995, p.31).A ton of grapes produces about 150 gallons of wine (Gallo, 1995). In 1971 the Gallo winery produced about 105,000,000 gallons of wine. That's a large operation by any standard.This paper is based on an interview with Ernest Gallo conducted during the period 1969–1971 by the Regional Oral History Office, Bancroft Library, University of California, Berkeley.

Abstract:

Twenty-one natural and unnatural phenolic compounds containing a carbohydrate moiety were synthesized and their structure–activity relationship (SAR) was evaluated for α-glucosidase inhibition and antioxidative activity. Varying the position of the galloyl unit on the 1,5-anhydro-d-glucitol (1,5-AG) core resulted in changes in the α-glucosidase inhibitory activity and notably, particularly strong activity was demonstrated when the galloyl unit was present at the C-2 position. Furthermore, increasing the number of the galloyl units significantly affected the α-glucosidase inhibition, and 2,3,4,6-tetra-galloyl-1,5-AG (54) and 2,3,4,6-tetra-galloyl-d-glucopyranose (61) exhibited excellent activities, which were more than 13-fold higher than the α-glucosidase inhibitory activity of acertannin (37). Moreover, a comparative structure-activity study suggested that a hemiacetal hydroxyl functionality in the carbohydrate core and a biaryl bond of the 4,6-O-hexahydroxydiphenoyl (HHDP) group, which are components of ellagitannins including tellimagrandin I, are not necessary for the α-glucosidase inhibitory activity. Lastly, the antioxidant activity increased proportionally with the number of galloyl units.

Abstract:

Drinking water is very important for the human body, humans will lose concentration and even feel dizzy when lacking water. At the North Serpong District Office there are several locations for drinking gallons of water, but when someone wants to drink but the gallon water runs out the person must tell the officer about it, so the clerk will refill the gallon. When you want to drink you have to hold the glass and open the tap manually to fill the glass and then close it when it's full. This research was conducted using the SDLC method and Black Box testing. This study discusses about designing a gallon water monitor and automatic glass filler with Wemos D1 that uses the ESP8266 chip as a microcontroller, load cell as a detector for the weight of the remaining gallon water and the weight of glass, ultrasonic sensors to measure the distance of glass and servo motor to move the water tap lever . The rest of the gallon water can be monitored through the internet using a smartphone, notifications are sent when the remaining 2 liters of gallon water and the glass can be filled automatically as much as 250ml.

Abstract:

Abstract To evaluate whether in classical galactosemia galactose (Gal), galactose-1-phosphate (Gal-1-P) and galactitol (Galtol) affect brain acetylcholinesterase (AChE) activity, various concentrations (1-16 mм) of these compounds were preincubated with brain homogenates of suckling rats as well as with pure eel Electroforus electricus AChE at 37 °C for 1 h. Initially, Galtol (up to 2.0 mм) increased (25%) AChE activity which decreased, thereafter, reaching the control value in high Galtol concentrations. Gal-1-P decreased gradually the enzyme activity reaching a plateau (38%), when incubated with 8-16 mM. However, when the usually found 2 mм of Galtol and 2 mм of Gal-1-P. concentrations in galactosemia were added in the incubation mixture simultaneously, brain AChE was stimulated (16%). Galtol or Gal-1-P modulated brain AChE as well as enzyme activity of E.electricus in the same way. Gal, Glucose (Glu) and glucose-1-phosphate (Glu-1-P) had no effect on AChE activity. It is suggested that Galtol as well as Gal-1-P can affect acetylcholine degradation acting directly on AChE molecule. Consequently the direct action of these substances on the enzyme might explain the brain cholinergic dysfunction in untreated galactosemia patients.

Abstract:

Chromatographic isolation of the 80% MeOH extract ofAcer ginnala(AG) yielded seven galloyl derivatives: gallic acid (1), ginnalin B (2), acertannin (3), maplexin D (4), maplexin E (5), quercetin-3-O-(2′′-galloyl)-α-L-rhamnopyranoside (6), and kaempferol-3-O-(2′′-galloyl)-α-L-rhamnopyranoside (7). This is the first study to report the isolation of compounds4and5from AG. Galloyl derivatives3–7exhibited potent radical scavenging activities, with5and7showing particularly strong inhibitory activities against nitric oxide production in lipopolysaccharides- (LPS-) stimulated RAW264.7 cells. In addition, oral administration of AG extract (500 mg/kg b.w.) improved symptoms of hyperglycemia and blunted the increases in serum GOT/GPT levels in a rat model of streptozotocin-induced diabetes. These results suggest that galloyl derivatives (1–7) are antioxidant and anti-inflammatory agents and that AG extract has potential as a functional material or novel herbal medicine for treating diabetes mellitus.

Neste trabalho, estudou-se o efeito do número de adultos de Trichogramma galloi Zucchi, 1988 liberados em semanas sucessivas, para o controle de Diatraea saccharalis (Fabricius, 1794). O experimento foi conduzido em março de 2003, com a cultivar SP 79-1011, de quatro meses de idade. Adotou-se o delineamento experimental inteiramente casualizado. Foram demarcadas quatro subáreas de 400 m² cada (20 m x 20 m), eqüidistantes 20 m. Cada parcela foi infestada artificialmente uma vez por semana com 20 casais de D. saccharalis (dois casais por gaiola, correspondendo a dez repetições por tratamento). Cada repetição correspondeu aos diferentes pontos de infestação. Repetiu-se esse procedimento por três semanas consecutivas, obtendo-se as posturas. Liberou-se T. galloi nas primeiras 24 horas após a infestação, no centro de cada uma das subáreas, nas seguintes quantidades (tratamentos): a- ausência de liberação (testemunha); b- 4.000 adultos (100.000 T. galloi/ha); c- 8.000 adultos (200.000 T. galloi/ha) e 10.000 adultos (250.000 T. galloi/ha). Com este trabalho ficou evidenciado que as liberações realizadas em áreas infestadas com ovos de D. saccharalis, em três semanas consecutivas, proporcionaram níveis elevados de parasitismoe que as melhores taxas de liberação de T. galloi para o controle de D. saccharalis, ficaram entre 150.000 e 175.000 parasitóides/ha.

Resumo: O objetivo deste trabalho foi avaliar o desempenho de Trichogramma galloi (Hymenoptera: Trichogrammatidae) sobre ovos de Diatraea flavipennella e D. saccharalis (Lepidoptera: Crambidae), assim como as características biológicas do parasitoide em ambos os hospedeiros, e elaborar a tabela de vida de fertilidade. Para isso, foram realizados testes com e sem chance de escolha e bioensaios para avaliar as características biológicas do parasitoide em ambos os hospedeiros. A tabela de vida de fertilidade foi elaborada por meio do parasitismo diário das fêmeas de T. galloi sobre os hospedeiros. Os resultados da percentagem de parasitismo em testes com chance de escolha mostraram uma melhor aceitação por parte de T. galloi quanto a ovos de D. flavipennella. Com relação aos parâmetros biológicos do parasitoide em ambas as espécies, não houve diferença significativa. Resultados da tabela de vida de fertilidade evidenciam que D. flavipennella e D. saccharalis permitem aumento populacional para T. galloi. O parasitoide T. galloi apresenta desempenho satisfatório em ambos os hospedeiros, sendo um potencial agente de controle para essas espécies.

Abstract:

Records of plasma calcium (Ca++), phosphorus (Pi), potassium (K+), sodium (Na+), chloride (Cl-), magnesium (Mg++), iron (Fe++), glucose, cholesterol, triglycerides and total protein levels were measured to determine the effects of exercise on occurrence of diurnal rhythms in Throughbred racehorses (n=7) under physical training. Physical activities consisted of gallop on the track and walking. Blood samples were collected from jugular vein every 4h over a 48h period. Plasma Ca++, K+, Mg++ and Na+ levels were obtained by flame photometry; and, Pi, Cl-, Fe++, glucose, cholesterol, triglycerides and total protein levels were measured by colorimetric tests using visible UV spectrophotometry. The data were analyzed using a 24h period to each exercise performed. Diurnal rhythm of Pi was observed when walking was the physical activity performed, and its acrophase occurred at the light period. Plasma triclycerides showed significant diurnal rhythms, with their acrophases occurring at the dark period, even when walking or gallop were performed. High intensity exercise (gallop) decreased triglycerides amplitude. No significant diurnal rhythms of other variables were found. Gallop, as physical activity, masked phosphorus diurnal rhythm. However, physical training did not influence triglycerides diurnal rhythm occurrence. High intensity exercise (gallop) just declined triglycerides amplitude.

Abstract:

Studies examining the effect of conditioning programs to improve the fitness of horses used in show jumping (Show Jumpers) are not available. Therefore, the effects of conditioning with 3 different interval type exercises were examined on 20 Show Jumpers divided into 3 groups matched by age and jumping performance level. Horses participated in 2 conditioning periods (CP) each of 6 weeks separated by 6 weeks without interval exercise. Training during a CP was the same for all horses but for one specific interval type exercise bout every 5th day. The specific interval exercise bouts were termed Gallop (n=13), Sprint (n=14) and Jump (n=13) and consisted of 4 times 90 s sessions each: Gallop were runs at the heart rate producing a blood lactate concentration (LA) of 4 mmol/l, Sprint were accelerations on the long-sides and decelerations in the short-sides of an arena, and Jump consisted of jumping obstacles of increasing height. Horses were submitted to 3 different standardised exercise tests (SET) before and after each CP: SETv4 (v4 is the speed at which a blood LA of 4 mmol/l is determined), SETjump (16 one jump obstacles in an elliptical course) and SETcourse (11 obstacles at the level of individually adjusted maximal degrees of difficulty). SETv4 showed that the v4 increased more in the Gallop (n=7) and Jump groups (n=7) than in the Sprint group (n=6). These results are based on fewer horses than the others because weather conditions did not allow for running this SET after the second period of conditioning. SETjump showed that blood LA and the level of fatigue estimated by the rider decreased after all interval type exercise bouts. A subjective fatigue score used by the rider in SETcourse improved regardless of the conditioning type of the horses, while their jumping technique improved with Gallop and Jump interval exercise only. Also the blood LA after SETcourse was lower after conditioning with Gallop and Jump interval exercise and the jumping technique improved according to an experienced independent observer in horses conditioned with Gallop, remained the same with Jump and decreased with Sprint interval exercise. In conclusion, all interval type exercise bouts examined improved parameters of fitness, but Gallop and Jump interval exercise improved more parameters than Sprint interval exercise bouts (v4, blood LA and fatigue level assessed by the rider after Gallop and Jump interval exercise; blood LA and fatigue level assessed by the rider after Sprint exercise), and Gallop as well as Jump interval exercise bouts improved the jumping technique too (as assessed by the rider and the independent observer for Gallop, and by the rider only after Jump interval exercise).

Durante o manejo da cultura da cana-de-açúcar são utilizados diversos produtos fitossanitários que podem afetar o desempenho de parasitoides, inimigos naturais da broca-da-cana, Diatraea saccharalis (Fabricius) e consequentemente, o controle biológico da mesma. Assim, objetivou-se avaliar em laboratório o efeito de herbicidas e reguladores de crescimento de plantas utilizados na cultura da cana-de-açúcar, sobre a sobrevivência, e parasitismo de adultos do parasitoide de ovos Trichogramma galloi Zucchi, assim como sobre a emergência do parasitoide (F1). Os produtos testados foram: Clomazone, Diuron + Hexazinone (herbicidas); Sulfometuron-methyl e Trinexapac-ethyl (reguladores de crescimento de plantas) nas maiores doses recomendadas à cultura. Ovos de D. saccharalis foram imersos durante 5 segundos em uma das caldas químicas e, após secos por 1 hora, oferecidos às fêmeas de T. galloi, totalizando 20 repetições. Avaliou-se a mortalidade e o número de ovos parasitados pela geração F0, assim como, a emergência da geração F1 de T. galloi, sendo os produtos classificados quanto à toxicidade, conforme percentual de redução da sobrevivência, parasitismo e emergência do parasitoide. Em relação à sobrevivência de T. galloi, número de ovos parasitados pela F0 e a emergência da F1, Clomazone e Trinexapac-ethyl foram classificados como levemente prejudicais.

During crop sugarcane management, several used pesticides can affect the performance of parasitoids, natural enemies of sugarcane borer, Diatraea saccharallis (Fabricius) and consequently the biological control ofit. Thus, the objective was to evaluate in laboratory the effect of herbicides and plant growth regulators used in the sugarcane crops on survival and parasitism in adults of the eggs parasitoids, Trichogramma galloi Zucchi. The products tested were the herbicides Clomazone and Diuron + Hexazinone, and the plant regulators Sulfometuron-methyl and Trinexapac-ethyl, all in the higher recommended dosages for sugarcane. The eggs of D. saccharalis were immersed during 5 seconds in chemical solutions and, after dry for 1 hour, offered to T. galloi females with 20 repetitions. We evaluated the mortality and number of eggs parasitized by the F0 generation of T. galloi, as well as the emergence of the F1. The products were classified by their toxicity, according to the percentage of reduction in the survival, parasitism and emergence of the parasitoid. In relation to the survival of adult T. galloi, the number of eggs parasitized by F0 as well as the percentage of F1 emergence, clomazone and trinexapac-ethyl were classified as slightly harmful. Diuron+hexazinone and sulfometuron-methyl were harmless in all parameters, except for parasitism, where diuron+hexazinone was classified as slightly harmful. We conclude that clomazone, diuron+hexazinone, trinexapac-ethyl and sulfometuron-methyl, are harmless or slightly harmful the survival and parasitism (F0) of T. galloi adults and emergence (F1) of this parasitoid in the laboratory.

Thirty weeks after sticking, Nellie R. Stevens holly had a greater total root dry weight compared to Dwarf Burford holly. There were no differences in total root dry weight for any transplant treatment, but root distribution was influenced. Cell pack and rose pot liners transplanted twenty weeks after sticking showed a reduction in root growth in the root sector between the radius of a quart pot and a trade gallon pot. Shoot growth was also reduced for cell pack and rose pot liners that were transplanted into trade gallon containers twenty weeks after sticking.

Abstract:

The treatment of human pulmonary artery smooth muscle cells with ET-1 stimulates the activity of PLD and NADPH oxidase, but this stimulation is inhibited by pretreatment with bosentan (ET-1 receptor antagonist), FIPI (PLD inhibitor), apocynin (NADPH oxidase inhibitor), and EGCG and ECG (catechins having a galloyl group), but not EGC and EC (catechins devoid of a galloyl group). Herein, using molecular docking analyses based on our biochemical studies, we determined the probable mechanism by which the catechins containing a galloyl group inhibit the stimulation of PLD activity induced by ET-1. The ET-1-induced stimulation of PLD activity was inhibited by SecinH3 (inhibitor of cytohesin). Arf6 and cytohesin-1 are associated in the cell membrane, which is not inhibited by the catechins during ET-1 treatment of the cells. However, EGCG and ECG inhibited the binding of GTPγS with Arf6, even in the presence of cytohesin-1. The molecular docking analyses revealed that the catechins containing a galloyl group (EGCG and ECG) with cytohesin-1–Arf6GDP, but not the catechins without a galloyl group (EGC and EC), prevent GDP–GTP exchange in Arf6, which seems to be an important mechanism for inhibiting the activation of PLD induced by ET-1, and subsequently increases the activity of NADPH oxidase.

Abstract:

The partition coefficients (logP) between n-octanol and water of 47 purified and characterized hydrolysable tannins were measured with the shake flask method utilizing UPLC and HPLC with UV detection. Results show that galloyl glucoses and gallotannins are clearly more hydrophobic than ellagitannins but the differences in hydrophobicity within ellagitannins are more varied than within galloyl glucoses or gallotannins. Most notable structural features that were found to influence the hydrophobicity of ellagitannins were the number of free galloyl groups, acyclic versus cyclic polyol, substitution of the anomeric position of glucose and 4C1 versus 1C4 conformation of the glucopyranose core.
