Combination of docosahexaenoic acid and Ginko biloba extract improves cognitive function and hippocampal tissue damages in a mouse model of Alzheimer's disease.

Alzheimer's disease (AD) is one of the most common neurodegenerative diseases characterized by a progressive loss of memory and other cognitive functions among elder people. Nowadays, natural antioxidants have been used to recover the quality of life for those with AD. In this study, we investigated, for the first time, the combined effect of docosahexaenoic acid (DHA) and Ginkgo bilobastandardized extract (EGb761) on AD mice.

Potential Antitumor Activity and Apoptosis Induction of Root Extract against Hepatocellular Carcinoma Cells.

(moghat) is used as a nutritive and demulcent drink. This study was performed to investigate the antiproliferative effects of moghat root extract (MRE) and its apoptotic mechanism in hepatocellular carcinoma (HCC) cells, HepG2 and Hep3B. MTT assay, morphological changes, apoptosis enzyme linked immunosorbent assay, caspase and apoptotic activation, flow cytometry, and immunoblot analysis were employed.

Trigonella foenum (Fenugreek) Induced Apoptosis in Hepatocellular Carcinoma Cell Line, HepG2, Mediated by Upregulation of p53 and Proliferating Cell Nuclear Antigen.

Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide and most current therapies are of limited efficacy. Trigonella foenum (Fenugreek) is a traditional herbal plant with antitumor activity, although the mechanisms of its activity remain unclear. Herein, a crude methanol extract was prepared from Fenugreek seeds (FCE) and its anticancer mechanism was evaluated, using HepG2 cell line.

Detection of shiga-toxin producing E. coli (STEC) in leafy greens sold at local retail markets in Alexandria, Egypt.

Leafy green vegetables, a popular and an indispensable ingredient of the daily menus of Egyptians' diets, currently presents a great concern in terms of microbiological hazards. To the best of our knowledge, this is the first report that provides scientific evidence for prevalence of shiga-toxigenic Escherichia coli (STEC) in leafy greens sold at open air local retail markets and superstores in the Egyptian environment. A total of 486 conventional and organic leafy green samples that are eaten raw were collected from different areas in Alexandria, evaluated for total E.

S6 kinase 2 is bound to chromatin-nuclear matrix cellular fractions and is able to phosphorylate histone H3 at threonine 45 in vitro and in vivo.

The activity of S6 kinases (S6K) is highly induced in cancer cells highlighting an essential role in carcinogenesis. The S6K family has two members: S6K1 and S6K2 which bear common as well as distinct features. In an attempt to identify S6K2 unique sequence features compared to S6K1, we applied extensive bioinformatic analysis and motif search approaches.
