Intracellular Ca(2+) signals constitute key elements in signal transduction. Of the three major Ca(2+) mobilizing messengers described, the most potent, nicotinic acid adenine dinucleotide phosphate (NAADP) is the least well understood in terms of its molecular targets [1]. Recently, we showed that heterologous expression of two-pore channel (TPC) proteins enhances NAADP-induced Ca(2+) release,...
in a greenhouse experiment, the effects of waterlogging, sewage sludge and manure on the uptake and concentrations of p, k, ca, mg and na in root and shoot of sunflower (helianthus annuus l.) were investigated. a factorial experiment based on completely randomized design with three replications including duration of waterlogging at five levels (0, 2, 4, 8, 22 days), source of organic fertilizer...
Rasoul Ghasemi1*, Zohreh Zare Chavoshi2 Department of Biology, University of Payame Noor, 19395 – 4697, Tehran (Received: 30 May 2012 Accepted: 24 April 2013) Abstract: Serpentine soils have some unusual properties such as low Ca and high Mg concentrations and also some of the heavy metals which are the inducers of high plant endemism. One of the possible causes of endemism c...
background : the present paper aims to study the effect of human and urban activities on the quality of groundwater within the city of khoy in terms of heavy metals, chemical salts, and minerals from the geological formations of this region. methods : samples were provided from 32 pumping wells and the concentration of heavy metals ( cd, cu, mn, pb, zn, fe, as, and b), the main ions (hco 3 ,so ...
Introduction: The reasons for choosing a field of study, depending on the type of discipline and degree, are different. This study aims to explore the reasons of choosing and continuing post-graduate major in medical education from viewpoint of students and graduates. Method: This qualitative research was conducted using content analysis method. Purposeful sampling was used for data collection...
Kettle holes are small inland water bodies known to be dominated by terrigenous material; however, the processes and structures that drive enrichment depletion of specific geochemical elements in column kettle hole sediment remain unclear. We hypothesized mobile (Ca, Fe, K, P) behave different from each other their transport, intermediate soil retention, final accumulation sediment. Topsoils tr...
the types of scion-rootstock compound and level of salinity affect on growth characteristics and concentration of nutrition elements of almond leaves and roots. in order to evaluate the effect of salinity stress on vegetative traits and concentration of nutrition elements of leaves and roots almond genotypes, a experiment was carried out with two factors; cultivar in four levels including ‘shah...
