AIMS OF THE STUDY Maca (Lepidium meyenii Walp) is consumed both as a sports supplement by strength and endurance athletes, and as a natural stimulant to enhance sexual drive. However, whether or not the postulated benefits of maca consumption are of scientific merit is not yet known. The aim of the study was therefore to investigate the effect of 14 days maca supplementation on endurance perfor...

The maturation of transfer RNA (tRNA) involves extensive chemical modification of the constituent nucleosides and results in the introduction of significant chemical diversity to tRNA. Many of the pathways to these modified nucleosides are characterized by chemically complex transformations, some of which are unprecedented in other areas of biology. To illustrate the scope of the field, recent ...

BACKGROUND Activity retention upon enzyme adsorption on inorganic nanostructures depends on different system parameters such as structure and composition of the support, composition of the medium as well as enzyme loading. Qualitative and quantitative characterization work, which aims at an elucidation of the microscopic details governing enzymatic activity, requires well-defined model systems....

The objective of this study was to characterize the non-enzymatice and enzymatic antioxidants of E. littorale Blume grown under wild condition. Aerial and sub-aerial parts of the plants exposed to different heat stress was analyzed for the non enzymatic antioxidants such as Tocopherol, Phenols, DPPH, FRAP and enzymatic antioxidants such as Polyphenol oxidase, Peroxidase, Catalase, Super Oxide D...

Optimization of enzymatic hydrolysis conditions contalupe (Cucumis melo var cantalupensis) seed protein Concentrate to achieve maximum antioxidant activity

Tyrosine hydroxylase (TH) is a rate-limiting step enzyme in the synthesis of catecholamines. Catecholamines function both as hormone and neurotransmitters in the peripheral and central nervous systems, therefore TH's expression and enzymatic activity is tightly regulated by various mechanisms. Several post-translational modifications have been shown to regulate TH's enzymatic activity such as p...

to determine the extent and the size of the environment pollution with heavy metals, biologicalmethods, investigating the enzymatic activity of soil can be applied. most frequently, the enzymes investigated in the soils threatened with anthropogenic contamination are phosphatases, dehydrogenases as reacting fastest to the increase in the content of heavy metals in the environment. the aim of th...

the antioxidant activity and phytoconstituents of the hydromethanolic extract of litchi chinensis (helc) fruit was explored in the present study. the antioxidant potential of extract has been evaluated using several antioxidant models and results were compared to standards. fruit extract showed effective reducing power and free radical scavenging activity in a dose-dependent manner. in case of ...
