salinity tolerance is a genetically and physiologically complex trait, controlled by quantitative trait loci (qtls). in order to map the qtls associated with agronomic and physiological traits, 149 doubled haploid lines derived from a cross between clipper (salt susceptible) and sahara 3771 (salt tolerant) barley genotypes were evaluated under natural saline-stress and non-stress conditions usi...

toxic heavy metals, such as lead (pb) and cadmium (cd) are widely used in industry and their accumulation in the living tissues may cause serious health problems and ecological hazards. twenty four moderately halophilic bacteria isolated from saline environments of iran were used to study their ability to bioremediation of lead and cadmium. amongst them, a gram-negative rod shaped bacterium, de...

backgroundbronchiolitis is the commonest cause of lower respiratory tract infection in infant. respiratory syncytial virus is the commonest cause of bronchiolitis. this study aimed to assess the efficacy of nebulized 3% hypertonic saline and salbutamol in the treatment of acute bronchiolitis in comparison with nebulized 0.9% saline and salbutamol.materials and methodsa prospective case second m...

this experiment was carried out to study the effect of sodium chloride from drinking water and feed intake on the quality of egs from laying hens. four hundred and twenty native and white leghorn laying hens ranging from 36 to 43 weeks of age were used. seven experimental treatments containing different levels of salt supplied by feed and/or drinking water were compared. increasing salt int...

Water salinity represents an environmental stress for many species. Amphibians are particularly sensitive because they are generally poor osmoregulators, and most species are completely absent from brackish and saline environments. We experimentally examined the effect of different salinity levels on larvae of the toad Bufo calamita L., a species that occupies freshwater ponds but can also bree...

Inland solar salterns established in the vicinity of Sambhar Lake are extreme saline environments with high salinity and alkalinity. In view of the fact that microbes inhabiting such extreme saline environments flourish the contemporary bioprospecting, it was aimed to selectively isolate slow growing and rare actinomycetes from the unexplored solar salterns. A total of 14 slow growing actinomyc...

background: during the detorsion of a torsioned ovary, oxidant agents are released and melatonin as an antioxidant can reduce ischemia. we studied the histopathological changes after using melatonin on experimental torsioned ovary in cat. objective: the aim of this experimental study was to investigate the effects of melatonin on histopathological changes in torsion – detorsion injury in cat ov...
