Recent studies suggest the potential of alpha-tocopherol as a gene regulator, possibly through peroxisome proliferator-activated receptor gamma (PPARgamma) activation due to the structural similarity of alpha-tocopherol to a PPARgamma ligand, troglitazone. Other investigators have suggested that a link exists between induction of the antioxidant enzymes Cu/Zn superoxide dismutase (SOD) and cata...

Community–academic partnerships have demonstrated potential for studying and improving community and environmental health, but only recently have their policy impacts been systematically studied. This case study highlights the evolution, research, and policy processes and outcomes of a community based participatory research (CBPR) partnership that has had multilevel impacts on health policy con...

Commercial pectolytic enzymes were investigated for their influence on phenolics and antioxidant activities of asparagus juice. The antioxidant activity of asparagus juice was analyzed according to 2,2'-diphenyl-l-picrylhydrazyl and 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) methods. The enzymes, with the exception of pectinase from Rhizopus sp., contained rutinase, which hydrolyzed ...

the dimerization constants of safranine t have been determined by studying the dependence of its absorption spectra on the temperature in the range 30–70 ◦c at different total concentrations of safranine t (1.03×10−5, 1.44×10−5 and 1.73×10−5 m). the monomer–dimer equilibrium of safranine t has been determined by applying mcr-als method on the absorption spectra. the quantitative analysis of the...

In the present work, optimization of pectinase-assisted and tri-solvent-mediated extraction of lycopene from waste tomato peels was carried out. The optimized parameters for enzymatic pre-treatment were 2% pectinase concentration, pH 5.5, 4-h incubation, 45 °C and 150 rpm. Maximum recovery of lycopene from tomato peels using optimized tri-solvent extraction was achieved at 45 °C, 120-min incuba...

Introduction: The aim of this study was to evaluate the effect of distilled water as an irrigation fluid for percutaneous nephrolithotomy (PCNL) on the serum concentrations of sodium. Materials and Methods: A total of 30 patients with kidney calculi underwent tubeless PCNL using distilled water as the irrigation fluid. During the procedure, intravenous Ringer lactate solution was used if necess...

The effect of changing the DNA concentration on RNA synthesis, protein synthesis, and cell growth rate was studied in Escherichia coli B/r. The DNA concentration was varied by changing the replication velocity or by changing replication initiation in a thymine-requiring strain with a mutation in replication control. The results demonstrate that changes in DNA concentration (per mass) have no ef...

objective: hydatidosis is one of the most important zoonotic diseases and surgery is still the main treatment for this problem. one of the side effects of hydatid cyst surgery is recurrence, thus, searching and assessment of some new agents such as medicinal plant extracts are very important. in the present study, the scolicidal effect of ethanolic extract of ziziphora tenuior l. (z. tenuior) w...
