BACKGROUND The aerial parts of Vitis vinifera (common grape or European grape) have been widely used in Ayurveda to treat a variety of common and stress related disorders. In the present investigation, the seed extract of V. vinifera was evaluated for antistress activity in normal and stress induced rats. Furthermore, the extract was studied for nootropic activity in rats and in-vitro antioxida...

This study was conducted to investigate how the activity and expression of certain paramount antioxidant enzymes respond to grape seed extract (GSE) addition in primary muscle cells of goats. Gluteal primary muscle cells (PMCs) isolated from a 3-week old goat were cultivated as an unstressed cell model, or they were exposed to 100 µM H2O2 to establish a H2O2-stimulated cell model. The activitie...

UNLABELLED Dental caries is considered a disease of high prevalence and a constant problem in public health. Proanthocyanidins (PAs) are substances that have been the target of recent studies aiming to control or treat caries. OBJECTIVE The aim of this in vitro study was to evaluate the efficacy of a treatment with grape seed extract, under cariogenic challenge, to minimize or even prevent th...

Background: Cylophosphamide is used alone or in combination with other drugs for treatment of neoplastic diseases. Hemorrhagic cystitis is a major potential toxicity and dose limiting side effect of cyclophosphamide. The aim of this study was to evaluate the effects of lycopene compared with some antioxidants for the prevention of cyclophosphamide induced hemorrhagic cystitis in rats. Methods: ...

BACKGROUND The objective of this in-vitro study was to evaluate the effect of grape seed extract (oligomericproanthocyanidin complexes [OPCs]) on the bond strength of composite resin to bleached enamel using 5th and 7th generations of bonding agents. MATERIALS & METHODS Eighty maxillary central incisors were randomly assigned to four groups as follows: Group I (n=20): no bleaching (control); ...

Objective: This study aimed to evaluate the effect of consuming grape seed extract with moderate-intensity aerobic training on the expression of miR-126 and miR-29 in the cardiac tissue in type 1 diabetic male rats. Materials and Methods: 40 rats with an initial weight range of 160-220 g were divided into five groups: Training + Extract, Training, Extract, Diabetic / Control, and Healthy / Con...
