erosion by wind is one of the most important factors in desert environment. prevailing winds can shift sand dunes and affect their accumulation. also, wind regime determines the direction of sand dune mobility. the aim of this research was to investigate sand drift potential using sand movement models. for this research, wind data between 1986 and 2005 from the meteorological station of yazd we...

Pars distalis-extract treatment of intact or 'hypophysectomized' chicken embryos resulted in a splenomegaly, perhaps of a host-versus-graft nature, by 17 and 17-5 days of incubation. Pars distalis grafts in intact embryos reduced spleen size, encouraged white-pulp follicle formation, but 'suppressed' red-pulp development. Adult spleen extract and bovine serum albumin did not change spleen sizes...

The aim of the study is to evaluated the neuroprotective effect of the red jasmine rice extract and tested the beneficial effect on memory impairments induced the rat ethylcholine mustard azirinium ion (AF64A) injection model of Alzheimer’s disease. After that the male Wistar rats were supplemented with the red jasmine rice extract at doses of 250 and 500 mg/kg BW once daily continually for 2 w...

An early sign of erythroblastic leukemia in rat was nodule formation in the spleen. Hyperplastic foci of stem cells, indistinguishable histologically from leukemic stem cells, were found in the red pulp whereas the malpighian corpuscles were uninvolved. Anemia is a normal phenomenon in immature rats and the spleen of the prepubertal rat possesses considerable hemopoietic potential. Pulse-doses ...

The present study is aimed at investigating the effect of nicotine administration on carbohydrate metabolic enzymes in the brain tissue of male albino rat. In vitro studies showed that Red grape (Vitis vinifera) has significant antioxidant activity, antimicrobial, anti-inflammatory action. Nicotine induces oxidative stress both in vivo and in vitro that causes a peroxidant/antioxidant imbalance...

light as an important environmental factor, influences many aspects of plant growth and development. leaves are different in some characters including stomatal behavior under shade or light conditions. in this study, the effects of different levels of light intensity on stomatal behavior of two rose cultivars, ‘gulmira’ and ‘red one’, were evaluated under controlled conditions. to obtain differ...

Benign Prostatic Hyperplasia (BPH) affects, worldwide, 50% of 60-year-old men. The Peruvian plant red maca (Lepidium meyenii) inhibits BPH in rodents. This study aimed to determine the effects of methanolic red maca extract and its n-butanol and aqueous fractions on expression of androgen and oestrogen receptors in rats with testosterone enanthate-induced BPH. Thirty-six rats in six groups were...

Turbulent-flow chromatography (TFC) on-line coupled to liquid chromatography mass spectrometry (LC-MS) is used to determine flavonoids and resveratrol in different types of wines. A fully automated system was developed in which 10 mL of sample (diluted wine) was passed over a TFC column, after which the retained analytes were separated by reversed-phase LC and detected by negative ion mode atmo...
