effects of salinity and drought on growth, contents of proline, malondialdehyde (mda), proteinand activity of antioxidative enzymes were studied in two trigonella species. seeds andexplants of t. foenum-graecum and t. aphanoneura were grown on murashige and skoogmedium (ms) complemented with iso-osmotic concentrations of nacl (0, 100, 150 mm) andmannitol (0, 180, 275 mm). growth and relative wa...

abiotic stresses including salinity are the major limiting factors of growth and crop production worldwide. microbial endophytes as the most important soil microorganisms, by modifying plants at genetical, physiological and ecological levels increase their yield per area unit and provide the possibility of crop production in saline and arid soils or climates with biotic and abiotic stresses. th...

hemiscorpius lepturus is medically important scorpion species present in the south and southwest part of iran, causing morbidity and mortality in children and adults. unlike other scorpions studied so far, the venom of h. lepturus is highly cytotoxic, that can be a reason for its complexity in clinical manifestations in patients stung by this scorpion. scarce studies showed the mechanism involv...

background: this study aims to evaluate the efficacy of silybum marianum seeds (smss) on blood biochemical profile of broiler chickens contaminated with aflatoxin b1 (afb1).  methods: combinations of three levels of afb1 (0, 250 and 500 ppb) with three levels of smss (0, 0.5, and 1.0 %) were incorporated into the basal diet (corn and soybean meal). the effect of nine experimental treatments was...

background : the rapid  development of  the mining and industry activities increased and many toxic metals  in the environment of the earth's crust has been dissipated  and t  has taken  risks to human exposure, inhalation. today evidence of many  diseases associated with environmental  factors  harmful to repellent bio systems is increasing gradually , the majority of these factors  were man-m...

the present study is related to the histochemical investigations on the changes in the intensity of reactions of axons, acid and neutral mucopolysaccharides, biologically active macromolecules, particularly glycogen and protein component as well as alkaline phosphatase (alpase) and adenosine triphosphatase (atpase) in the cells lining the olfactory epithelium of catla catla . the intense reacti...

background: exercise can change the release of numerous cytokines and modulate their receptor systems. dietary ω-3 lipids may decrease the levels of inflammatory cytokines and prostaglandins (pgs). therefore, in this study, we investigated the effects of exercise and eicosapentaenoic acid (epa) supplementation, with or without vitamin e, on the blood levels of il-2, tnf-α, catalase, glutathione...
