The present study compared the effects of subchronic treatment with melatonin administered via subcutaneous osmotic minipumps for 14 days (10 mg/kg per day) on kainic acivd (KA)-induced status epilepticus, oxidative stress and expression of heat shock protein (HSP) 70 in the frontal cortex and hippocampus between normotensive Wistar rats and spontaneously hypertensive rats (SHRs). SHRs showed i...

Activation of the neurokinin 3 receptor (NK3R) by a receptor agonist, hypotension, and hyperosmolarity results in the internalization of NK3R expressed by magnocellular neurons and the release of vasopressin (VP) and oxytocin (OT) into the circulation. The contribution of NK3R activation to the release of VP and OT in response to hyperosmolarity and hypotension was evaluated by measuring the re...

sugarcane bagasse contains cellulose, lignin and hemicellulose, 39-42%, 20-25% and 25-27% respectively. so it is can be used as a sugar source in many processes. lignin and hemicellulose must be removed before hydrolysis of cellulose. several different pretreatment approaches have been studied. the purpose of this research is comparison of acid, ozone and combination of ozone-acid as pretreatme...

introduction: the use of lopinavir/ritonavir (lpv/r) has decreased morbidity and mortality due to human immunodeficiency virus (hiv); however its use could be impaired by hepatotoxicity. therefore, this study was designed to investigate the effects of melatonin (mt) and alpha lipoic acid (ala) on lpv/r-induced hepatotoxicity in male albino rats. methods: rats were divided into groups and treate...

drying is one of the most important steps in raisin processing. during this step, initial moisture content decreases up to 15-17% (db) for suitable storage. achieving optimum drying conditions can affect the processing time and improve raisin quality. temperature, air velocity and pretreatment are important factors in the quality of the grape drying process. in this research, the effect of temp...

Osmotic adjustment is generally regarded as an important adaptation of wheat to drought. Because it helps to maintain turgor and cell volume, osmotic adjustment is often thought to promote growth, yield, or survival, of plants in dry soils. However, a physiological rationale for such views is lacking. This study was conducted to determine the effect of osmotic adjustment and some of its compone...
