the aim of our work was to compare cytotoxic and membrane-damaging effects of o. majorana l. essential oil and linalool on hep g2 and to investigate their possible protective (antioxidant) effects against h2o2 induced membrane damage. the oils were investigated by gc and gc-ms and antioxidant activity was evaluated by dpph and -carotene–linoleic acid assays. assessment of cell viability was ma...

Background & Aim: Aloe vera is used in the food and pharmaceutical as an aid to effective treatment. The purpose of this study is to improve growth, increase production of valuable metabolites and increase the sugars in Aloe vera gel with low cost and high efficiency under water stress conditions. Experimental: In this study, Aloe vera potted in greenhouse conditions...

Several studies recognized an overlap between CFS (chronic fatigue syndrome) and POTS (postural tachycardia syndrome). We compared the autonomic and neurohormonal phenotype of POTS patients with CFS (CFS-POTS) to those without CFS (non-CFS-POTS), to determine whether CFS-POTS represents a unique clinical entity with a distinct pathophysiology. We recruited 58 patients with POTS, of which 47 wer...

Polymorphonuclear neutrophils (PMN) from patients with chronic granulomatous disease of childhood have impaired bactericidal activity and are deficient in diphosphopyridine nucleotide, reduced form of, (NADH) oxidase. Since hydrocortisone had been shown to inhibit NADH oxidation, experiments were undertaken to determine the effect of hydrocortisone on several parameters of human PMN function. T...

OBJECTIVE To examine a large UK cohort of patients with postural tachycardia syndrome (PoTS), to compare demographic characteristics, symptoms and treatment of PoTS at one centre compared to the largest patient group PoTS UK and to verify if their functional limitation is similar to patients with chronic fatigue syndrome (CFS). DESIGN A cross-sectional study assessed the frequency of symptoms...

This study was aimed to investigate the diversity and function of bacterial population associated with Gigaspora margarita spores. The fungus was propagated in sterilized sand/soil pots using alfalfa (Medicago sativa), grain sorghum (Sorghum bicolor), or maize (Zea mays) as host plants, or in sterilized vermiculite pots using alfalfa as host plants, respectively. Bacteria were isolated from the...
