Guarana has great agricultural potential and is largely used therapeutically and in the production of non-alcoholic energy drinks. Genomic and proteomic studies are crucial to identify proteins that play central roles in the maintenance and viability of fruits, as well as to identify proteins related to the main metabolic pathways. However, the success of any protein analysis starts with the pr...

BACKGROUND Ardisia crispa Thunb. D.C is used mostly in some parts of the Asian region by traditional practitioners to treat certain diseases associated with oxidative stress and inflammation including cancer and rheumatism. In Malaysia, it is popularly known as 'Mata Ayam' and local traditional practitioners believed that the root of the plant is therapeutically beneficial. METHODS The cytoto...

abstract anti-nociceptive activity of aerial parts of phytolacca americana were investigated, using the hot plate method in mice. results of the present study showed that the aqueous methanolic extract of aerial parts of p. americana produced a statistically significant increase in pain threshold after 30 min, in comparison with the control, at adose of 190 mg kg-1 (p<0.001). the activity was c...

Received: Revised: Accepted: November 13, 2014 February 12, 2015 February 21, 2015 Gentamicin-induced nephrotoxicity is associated with free radicals generation in kidney tissue. Medicinal plants contain bioactive constituents that act as natural antioxidants, which can protect the biological system from oxidative stress. In this study, phytochemical constituents of aqueous extract of Calotropi...

the side effects of synthetic antioxidants have been considered in different studies. accordingly, there is an increasing interest toward the use of natural substances instead of the synthetic ones. in this study, the aqueous and ethanolic extracts of pistacia vera leaves and fruits as well as hydroalcoholic extract of gum were tested for a possible antioxidant activity using in vitro methods. ...

Cell damage induced by free radicals has been implicated as causal factor in a wide variety of human diseases such as cancer, neurodegenerative disorders. Scientific recognition of natural antioxidants may be helpful in preventing many diseases. Aqueous Date fruit extract (ADFE)- PC12 cell line. ADFE at concentrations of 0.1-10% containing 0.005% H2O2 and H2O2 at concentrations of 0.01-1% conta...

Introduction. Catharanthus roseus (L.) is used in some countries to treat diabetes. The aim of this study was to evaluate the hypoglycemic activity of extracts from the flower, leaf, stem, and root in normal and alloxan-induced diabetic mice. Methods. Roots, leaves, flowers, and stems were separated to obtain organic and aqueous extracts. The blood glucose lowering activity of these extracts wa...

BACKGROUND We hypothesized that C. borivilianum root, known to improve male reproductive performance, prevents impairment in characteristics, morphology and elevation of oxidative stress in sperm of diabetics. We therefore investigated the effect of aqueous root extract of C. borivilianum on these parameters in diabetic rat model. METHODS C. borivilianum root aqueous extract (250 and 500 mg/k...
