Iran is located in a hot and dry region. As a result of low precipitation and a vast area of salty and alkali soil, osmotic pressure is very high in most parts of the country (i.e., osmotic potential is more negative). In the present study four levels of osmotic pressure (-0.25, -0.35, -0.45, -0.50 MPa) were created artificially, by polyethylene glycol (PEG) and treatment of three seed types, n...

Drought stress influences seed germination and seedling growth of many plants. Seed coating is technique of covering seeds with adhesive agents to improve seed performance and plant establishment and could be used to alleviate the negative effects of osmotic stress. In order to solve the problem of low germination and poor vigor of sweet corn under osmotic stress conditions (0, -0.3, -0.6 and -...

BACKGROUND In the last years, the biotechnological production of platform chemicals for fuel components has become a major focus of interest. Although ligno-cellulosic material is considered as suitable feedstock, the almost inevitable pretreatment of this recalcitrant material may interfere with the subsequent fermentation steps. In this study, the fungus Ustilago maydis was used to produce it...

This study examined the effects of freezing, storage, and cabinet drying on the anthocyanin content and antioxidant activity of blueberries (Vaccinium corymbosum L). Fresh samples were stored for two weeks at $\5^\circ$ C while frozen samples were kept for up to three months at $-20^\circ$ C. There were two drying treatments, one including osmotic pretreatment followed by cabinet drying and the...

The present study aimed to evaluate the effect of chronic co-exposure to chlorpyrifos (CPF) and deltamethrin (DLT) on erythrocyte osmotic fragility, lipid peroxidation and the ameliorative effect of alpha-lipoic acid (ALA) on erythrocyte fragility. Thirty-six male Wistar rats divided into six groups of six rats each were used for the study. Groups I (S/oil) and II (ALA) were given soya oil (2 m...

The volume-sensitive chloride current (ICl,swell) is found in the mammalian myocardium and is activated by osmotic swelling. The goal of this study was to examine the importance of the tyrosine kinases focal adhesion kinase (FAK) and Src kinase in cardiac ICl,swell regulation. Neonatal rat ventricular myocytes were cultured on collagen membranes and infected with adenovirus expressing beta-gala...

Using the human Intestine 407 cell line as a model, we investigated a possible role for tyrosine kinase(s) in regulating the ion efflux pathways induced by hyposmotic stimulation (regulatory volume decrease, RVD). Pretreatment of 125I(-)-and 86Rb(+)-loaded cells with the phosphotyrosine phosphatase inhibitor sodium orthovanadate (200 microM) potentiated isotope efflux triggered by mild hypotoni...

in this study, the effect of edible coating and osmotic dehydration, as pre-treatments before drying of cucurbit, were investigated. cucurbit samples were cut spirally and coated by carboxy methyl cellulose (cmc) 1% and ascorbic acid 0.1% solutions and then processed by osmotic dehydration. proportion of sample to solution was 1:10 and the solution containing sucrose %45, salt%25 and citric aci...
