Arginine vasopressin (AVP) has been implicated in a wide variety of social behaviors ranging from affiliation to aggression. However, the precise functional involvement of AVP in intermale aggression is still a matter of debate. In fact, very little is known about AVP release patterns within distinct brain regions during the display of intermale aggression and, in turn, the behavioral consequen...

this study has been carried out to determine the accumulation of heavy metals (arsenic, copper, lead, tin and zinc) in fish samples collected from former tin mining catchment. total eight types of fish family having fifteen different species are identified. cyperinidae is the most abundant family with eight different species found in the catchment. fish samples were analysed by using inductivel...

Both the processing and release of secretory granules involve water movement across granule membranes. It was hypothesized that the water channel aquaporin (AQP)1 directly contributes to the recruitment of renin-positive cells in the afferent arteriole. AQP1(-/-) and AQP1(+/+) mice were fed a low-salt (LS) diet [0.004% (wt/wt) NaCl] for 7 days and given enalapril [angiotensin-converting enzyme ...

One of the major problems about the chelant-enhanced phytoextraction is the potential metal leaching associated with chelant application. A glasshouse pot experiment was conducted to investigate phytoextraction efficiency of common reed (Phragmites australis (Cav.) Trin. ex Steudel) for Lead and Chromium and to determine EDTA (ethylenediaminetetraacetic acid) enhancement of the mobility and phy...

industrial processes release a range of gaseous and particulate pollutants containing heavy metals into the air. lack of enough attention to the design, installation, repair and maintenance of gas and dust filtration systems in industries, is one of reasons of increasing the emissions of these pollutants. hereon, the steel making processes is one of emission sources of heavy metals. according t...

in this paper the risk of heavy metals discharged from the acidic sludge leachate into groundwater in a landfill located in fajr industrial area )garmsar( has been assessed using iwem software. acidic sludge as one of the industrial hazardous wastes is produced during purification of used oil with mienken )acidic( method. the concentrations of heavy metals )cd, ni, co, pb, zn, mn, cu( in the ac...

background: considering high importance of heavy metals residue from view point of food safety, this study was conducted to determine the contents of chromium (cr), lead (pb) and cadmium (cd) in different tissues (liver, heart and muscle) of marketed chickens in mashhad, iran. methods: chicken tissues were collected from four popular brands distributed in different markets in mashhad, followed ...

in this study, concentrations of heavy metals in soils around a zn-smelter in qeshm island, iran, are investigated. calculated geoaccumulation index (igeo), contamination factor (cf), and contamination degree (cdeg) values indicate surface soil contamination by toxic metals (as, cd, pb, and zn). the results also indicate that most contaminated areas are located in the vicinity of the smelter an...

Introduction: Breast cancer is the second cause of mortality among women. Early detection is the only rescue to reduce the risk of breast cancer mortality. Traditional methods cannot effectively diagnose tumor since they are based on the assumption of well-balanced dataset.. However, a hybrid method can help to alleviate the two-class imbalance problem existing in the ...
