the present study describes the radiation-induced effects on nutritional quality and on anti-nutritional factors of sorghum grain: effects of electron beam (er) and gamma irradiation (gr) at doses of 10, 20 and 30 kgy and infrared irradiation (ir) at 60, 90 and 120 s on the chemical composition, mineral content and bioavailability, in vitro protein and starch digestibility, total phenolic compo...

in this work, mg-doped zno nanostructures were prepared in water under ultrasonic irradiation for 60 min without using any organic compounds or post preparation treatments. the prepared samples were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem), energy dispersive analysis of x-ray (edx), diffuse reflectance spectroscopy (drs...

in this paper, we have described the size-controlled synthesis of gold nanoparticles based on the reduction of au3+ (haucl4 ) using molybdophosphoric acid (h3[pmo12o40 ], hpmo) under uv-irradiation. in the process, hpmo plays the role of photocatalyst, reducing agent and stabilizer and propan-2-ol acts as a sacrificial agent. this method allows the synthesis of uniform hexagonal nanoparticles w...

background & aim: a simple and rapid microwave- assisted extraction (mae) procedure was developed and optimized for the isolation of borneol and bornyl acetate from ferulago macrocarpa. ferulago macrocarpa (apiaceae) is an endemic plant in iran. experimental: dried powdered aerial parts of plants were soaked in water and irradiated with microwave in a clevenger extraction approach under opt...

background: the exposure of cell lines to low-dose irradiation leads to changes at molecular level, which may induce adaptive response. we examined radio-adaptive doses effect on human colorectal adenocarcinoma cell line (ht29) and human fetal fibroblasts (mrc5) cell line followed by hyper and hypo fractionation regimes, with main purpose to decrease cell viability in ht29, and at the same time...

in the present study, an attempt has been made to synthesize 3-methyl-4-arylmethylene isoxazole-5(4h)-one derivatives through sonication of hydroxylamine hydrochloride, ethyl acetoacetate and benzaldehyde derivatives in the presence of imidazole as a novel and effective catalyst in aqueous media. this green reaction under ultrasound irradiation has advantageous compared to conventional procedur...

us damages to the ovary storage and the matrix muscle state. some of these patients may admit to infertility clinics for having pregnancy and on the other hand hormonal administration for superovulation induction is a routine procedure in assisted reproduction technology (art) clinics.objective: this study aimed to investigate fertility and fetuses of hormone treated super ovulated female mice ...

Chronic irradiation with low-dose-rate 137Cs-γ rays inhibits the differentiation of human neural progenitor cells and influences the expression of proteins associated with several cellular functions. We aimed to determine whether such chronic irradiation influences the expression of proteins associated with PC12 cells. Chronic irradiation at 0.027 mGy/min resulted in inhibition of NGF-induced n...

Background: Tumor radioresistance leads to a reduction in the efficiency of radiation therapy. It is very important to explore the cellular mechanisms leading to radioresistance and to find potential therapeutic targets, which might improve the efficacy of radiation therapy. This study was to investigate the role of ataxia-telangiectasia mutated (ATM) and murine double minute X (MDMX) in radior...

background: to evaluate the radioprotective potential of punica granatum fruit rind extract (pgre) in mouse testes. materials and methods: adult male mice were divided into four groups. group i was kept without any treatment. group ii was irradiated with 8gy co60 gamma irradiation and group iii was given pgre one hour before irradiation. group iv was fed with pgre at the rate of 10 mg/kg body w...
