Objective: The present study was conducted to investigate the antioxidant and hepatoprotective activity of the hydro-alcoholic extract of aerial parts of Artemisia dracunculus (HAAD) against CCl4-induced hepatotoxicity in rats. Materials and Methods: The antioxidant activity was evaluated by reducing power, 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and 2, 20-azino-bis (3-ethylbenzothiazoline-6-sulf...

diabetes mellitus is one of the most common causes of neuropathy. although antioxidant and antidiabetic effects of the aqueous extract of purslane (portulaca oleracea) (aeop) have been demonstrated before by other researchers, we did not find any study that assessed the psychobiological effects of aeop in diabetes induced animals. thirty ovariectomized (ovx) female wistar rats were randomly div...

results low concentrations of agnps and short incubation times can have the maximum positive impact on the peroxidase activity, and in the present study the highest activity was seen at a concentration of 40 mg/l and two hours of incubation time. conclusions this study suggests that changes of enzyme activity can occur as a result of the effect of silver nanoparticles on enzyme conformation, in...

Nitrilases have a high potential for application in organic chemistry, environmental technology, and analytics. However, their industrial uses require that they are produced highly active robust forms at reasonable cost. Some syntheses catalyzed by nitrilases already reached level of technological readiness. This has been enabled the large-scale production recombinant catalysts. Despite some pr...

Revealing mechanisms underpinning cell function requires understanding the relationship between different biochemical reactions in living cells. However, our capabilities to monitor more than two cells are limited. Therefore, development of methods for real-time multiplexing is fundamental importance. Here, we show that data acquired with multicolor (mcFLIM) or spectrally resolved (sFLIM) fluor...

Exploitation of the biodiversity native wine yeast is a means modifying sensory characteristics wine. Samples from different regions in China were analysed to screen isolates as potential starter cultures. Through morphological and molecular biological analyses, we found six species, belonging four genera (Hanseniaspora, Saccharomyces, Rhodotorula Metschnikowia). These species subjected stress ...

ABSTRACT RNA-seq analysis of Cupriavidus necator NH9, a 3-chlorobenzoate degradative bacterium, cultured with 3-chlorobenzaote and benzoate, revealed strong induction genes encoding enzymes in degradation pathways the respective compound, including to convert benzoate chlorocatechol catechol, respectively, ortho-cleavage pathway for conversion central metabolites. The transporters, components s...

Mucopolysaccharidosis IIIA (MPS IIIA) is a lysosomal storage disorder (LSD) caused by deficiency of N-sulphoglucosamine sulphohydrolase, which one four enzymes involved in heparan sulfate degradation. Traditional methods used for MPS diagnostics usually constitute selective screening, based on the analysis urinary glycosaminoglycans, further enzymatic assays leukocytes, and mutation analysis. N...

Flourensia fiebrigii is a plant used in traditional medicine the Argentine Calchaquí Valley as purgative, expectorant, anti-rheumatic and anti-inflammatory. The aim of this study was to analyze macroscopic microscopic characteristics F. leaf stem, phytochemical composition leaves ethanolic extracts validate its use description stem carried out. Two (immersions tinctures) from were obtained. ana...

Background: Aging is a process caused by oxidants and aging-related enzymes. Therefore, the inhibition of these processes can exacerbate anti-aging agents. This study aimed to evaluate antioxidant activities leaf extracts from seven herbs used in traditional Thai herbal remedies. Methods: Researchers assessed total levels phenolic content (TPC), antioxidant, anti-collagenase, anti-tyrosinase ac...
