background: leptin plays a key role in the regulation of energy expenditure and is known to circulate in both free and bound forms. soluble leptin receptor (sob-r) is a unique circulating form of leptin receptor that can bind to leptin. leptin and leptin receptor have been implicated in processes leading to breast cancer initiation and progression. our study was aimed to investigate the relatio...

high strength fresh leachates generated at a new disposal trench, compost plant and partially stabilized leachate of an older trench were characterized in terms of anaerobic degradation at laboratory batch scale at 35oc. fresh leachate had extremely high cod of 66,710 – 89,501 mg/l along with low ph of 4.1-5.9 in contrast to older and therefore partially stabilized leachate with a cod of about ...

to study the effect of salinity stress on some physiological attributes of four grape cultivars in vineyards of urmia in iran, an experiment was carried out as factorial arrangement in randomized complete block design with four replications. experimental factors included: grape cultivars qazel ozum, qareh shireh, tabrzeh and dizmari, and salt concentrations 0, 25, 50 and 100 mmol l-1 and locati...

long-term application of fertilizers containing p, especially organic fertilizers, usually increases the water soluble and available p of soil and at the same time may result in p accumulation in soil. organic fertilizers may also increase movement of p in the soil profile that could result in surface and ground water pollution. an experiment was conducted on field plots that received three app...

objective: oxidative stress as a consequence of aging can induce infertility in males. in this study, we have investigated the effects of aging on sperm parameters, intra-spermatic water soluble antioxidants, reactive oxygen species (ros), and in vitro blastocyst formation. methods: we chose 5 older nmri male mice (10-12 months) and 5 younger nmri male mice (2-3 months). sperm parameters, ros, ...
