Secretion of neurotransmitters is initiated by voltage-gated calcium influx through presynaptic, voltagegated N-type calcium channels. These channels interact with the SNARE proteins, which are core components of the exocytosis process, via the synaptic protein interaction (synprint) site in the intracellular loop connecting domains II and III of their a1B subunit. Interruption of this interact...

a-Adrenergic receptor (AR) activation enhances sodium retention in certain forms of hypertension. The objective of the present study was to understand the role of a-ARs in regulating sodium transport by distal tubules (DT). DT cells were isolated from kidneys of spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats at 6 weeks, when hypertension is developing, or at 12 weeks, when hy...

Jujube (Ziziphus jujuba Mill.) is an important medicinal plant in Iran. Jujube fruit contains amino acids, polysaccharides and microelements.Ripened jujube fruits were collected at fully mature stage from two research collection of jujube at Khaf and Birjand centers in south Khorasan province, Iran, early in September, 2015.The physicochemical properties and antioxidant capacity were i...

introduction: weather features and their variations have an important role in the yield of agricultural products, especially in rain-fed conditions. the main metrological variables that affected yields consist of precipitation, temperature, soil moisture and solar radiation. also, drought is one of the major constraints to production, especially the mid-season drought which occurs during the po...

Rapid climate change represents one of the top threats to biodiversity, causing declines and extinctions of many species. Range shifts are a key response, but in many cases are incompatible with the current extent of protected areas. In this study we used ensemble species distribution models to identify range changes for 21 reptile and 16 amphibian species in Romania for the 2020s and 2050s tim...

heavy metals such as cu(ii) and pb(ii) are among the hazardous pollutants that lead to severe ecological problems and have a toxic effect on living organisms. the removal of cu(ii) and pb(ii) by iranian bentonite experiment were conducted in single component and multi component systems. the bentonite from the birjand area was characterized by x-ray diffraction pattern and ftir spectroscopy. the...
