The development of oil and gas production together with the fruit in nearby areas North Patagonia, Argentina, suggests aquatic pollution scenarios which include permanent combined short events pesticides application. It has been reported that hydrocarbons activate aryl hydrocarbon receptor (AhR) pathway rainbow trout, Oncorhynchus mykiss, insecticide Chlorpyrifos (CPF) interacts these effects. ...

this paper describes optimization method that combines the plackett-burman design, a factorial design and the response surface method, which were used to optimize the medium for the production of l-asparaginase by serratia marcescens sb08. four medium factors, from out of 11 medium factors, were screened by plackett-burman design experiments and subsequent optimization process to find out the o...

In this research, we have demonstrated a one-step electrochemical deposition of dendritic gold nanostructures (DGNs) on graphite rod (GR) electrode without any template, seeds, surfactants, or stabilizers. Three methods, namely, constant potential amperometry (CPA), pulse amperometry, and differential voltammetry, were used for DGN synthesis GR further application in enzymatic glucose biosensor...

Two Citrus sinensis (L.) phosphomannose isomerase (PMI) genes, CsPMI1 and CsPMI2, were evaluated as novel selectable markers in mature citrus transformation. Transgenic shoots produced after transformation of Kuharske rootstock with each PMI construct selected on six treatments mannose sucrose. For CsPMI1, there no significant differences among the various sucrose for mean number positive (PS),...

This study was conducted to investigate the effects of different silicon supplements and postharvest treatments on growth and yield of gerbera in a greenhouse experiment. Silicon supplements were including potassium silicate at three concentrations (0, 140 and 200 mg L−1), sodium silicate at three concentrations (0, 50 and 100 mg L−1) and rice hull ash (RHA) at three concentrations (0, 50 and 1...

Supplementation has beneficial effects in immune system and can antioxidant enzymes activity increases during the exercise and protects the tissue against the oxidative stress. L-Carnitine is a famous Supplement and helps to protect against the oxidative stress during and after intense or prolonged exercise. The aim of this study was to investigate the effect of L-Carnitine supplementation on t...

An efficient procedure has been developed for callus induction and cell suspension cultures of C. saxicola for the first time. Explant selection was carried out among leaf, stem and root to select a suitable type of explants capable of higher callus formation. Leaf explants thus selected showed maximum response to callus induction (67.1%). Modified B5 medium supplemented with 0.5 mg l(-1) 2,4-D...

This study was conducted to evaluate the effect of preservative solutions on vase life, number of bacteria in the end of stem and in vase solution of cut gerbera 'Double Dutch' and 'Red Explotion'. Cut flowers were pulse-treated with nano-silver (2, 4, 6, 8 or 10 mg L-1) and thymol (12.5, 25, 50, 75 or 100 mg L-1) +5 % sucrose. Experiment was conducted in completely randomized design with 5 rep...

BACKGROUND Patients with compensated Child-A cirrhosis have sub clinical hypovolemia and diuretic treatment could result in renal impairment. AIM To evaluate the changes in renal functional mass as reflected by DMSA uptake after single injection of intravenous furosemide in patients with compensated liver cirrhosis. METHODS Eighteen cirrhotic patients were divided in two groups; eight patie...

xylitol is the first rare sugar that has global market due to having beneficial health properties and being an alternative to current conventional sweeteners. biotechnological production of xylitol by candida tropicalis dsm 7524 as an alternative to chemical method for the fermentation of xylose to xylitol was studied. banana peel was used as a substrate for xylitol production. hydrolysate was ...
