the anti-apoptotic gene bcl-2 is located in mitochondria, but it is uncertain whether its expression affects hepatocyte survival in ischemia/reperfusion (i/r) injury. this experiment was designed to evaluate the role of folic acid in expression of bcl-2 in i/r in rat liver. eighteen wister rats were divided into sham-operated controlgroup (c) (n=6), i/r group (n=6), folic acid treated group whi...

In order to find the most effective method to overcome seed dormancy in Teucrium chamaedrys  L. medicinal plant species the effect of some chemical and physical breaking methods including: cold stratification (5 °C), scarification with sandpaper, stratification with needle, concentrated sulfuric acid, gibberellic acid and combination of these methods were investigated. Treated seeds along with ...

In this research the effect of application of different levels of folic acid and time on some quality and agronomic characteristics of strawberry (cultivar Paros) was investigated. The plants were treated by folic acid with concentrations of 0, 20 and 40 mM at two stages (30 days after planting and first blooming) as a factorial experiment using a randomized complete block design with four repl...

Background: Due to high content of unsaturated fatty acids, trout is susceptible to oxidative spoilage. In this study, the effects of Thymus vulgaris Essential Oil (EO) and extract on oxidative stability of cooked rainbow trout fillet during four months frozen storage period were investigated. Methods: Three groups of fish fillets were treated with thyme EO and three other groups were treate...

background: chronic arsenic toxicity (arsenicosis) due to drinking of arsenic contaminated ground water is a global problem. however, its treatment is unsatisfactory. methylation of arsenic facilitates its urinary excretion. persons with relatively lower proportion of urinary dimethyl arsenic acid (dma) are found to have at greater risk of developing symptoms of arsenicosis including its compli...

abstract application of chemicals which activate plant defense mechanisms before pathogen attack without environmental side effects of protective chemical agents have stimulated great deal of researches in this area. one of the important crops in the world is tomato and recently recognized as a model plant for plant-pathogen interactions. tomato early blight is one of the most devastating disea...

the characterizations of natural diatomite from birjand deposit (iran) were studied such as chemical compositions, specific surface area, total pore volume, pore size distribution and xrd. the diatomite that was treated only with sulfuric acid displayed a larger surface area, expanded total pore volume and increased pore size in comparison with both washed natural diatomite with deionized water...
