Population and function analysis of cultivable bacteria associated with spores of arbuscular mycorrhizal fungus Gigaspora margarita
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...
متن کاملContractile activity-induced oxidative stress: cellular origin and adaptive responses.
Previous studies have reported that oxidizing free radical species are generated during exercise, and there has been considerable interest in the potential effects of these on exercising tissues. We hypothesized that contracting skeletal muscle was a major source of oxidizing free radical species and that untrained skeletal muscle would adapt to the oxidative stress of a single short period of ...
متن کاملPolyphosphates in intraradical and extraradical hyphae of an arbuscular mycorrhizal fungus, Gigaspora margarita.
The amount of polyphosphate in the intraradical and extraradical hyphae of Gigaspora margarita was estimated from successive extractions with trichloroacetic acid (TCA), EDTA, and phenol-chloroform (PC). In the intraradical hyphae, most of the polyphosphate was present in TCA- and EDTA-soluble (short-chain and long-chain) fractions, whereas most of the polyphosphate in the extraradical hyphae w...
متن کاملI-33: Oxidative Stress Responses in EarlyPregnancy
Background: Survival of the conceptus is dependent on continuous progesterone signaling in the maternal decidua but how this is achieved under conditions of oxidative stress that characterize early pregnancy is unknown. Materials and Methods: Laboratory-based analysis of endometrial biopsies and primary endometrial cultures. Results: Using primary cultures, we show that modest levels of reactiv...
متن کاملThe comparative effect of fasting with and without caloric restriction in Rat on oxidative stress parameters
Introduction: Fasting, like Islamic Ramadan Fasting, has been associated with health benefits. Islamic Ramadan fasting, a form of caloric restriction (CR) or alternate day fasting that. Studies suggest a comparable effect of ADF and caloric restriction. Despite the fact that fasting can be considered as a form of dietary restriction, fasters tend to have difficulty to reduce their food intake d...
