the mineral contents of centaura leave and seeds were determined by inductively coupled plasma-atomic emission spectroscopy (icp-aes). macro element concentrations (p, k, ca, mg and s) of samples were found at high levels. k was established at high level in both leave and seed samples of centaurea. while k contents of leaves changes between 7254.10 mg/kg (centaurea lycaonica) and 26396.36 mg/kg...

diagnosis and recommendation integrated system (dris) can be used as efficient methods to interpret the results of plant analysis and the nutritional diagnosis in crops and fruit trees. to establish dris norms in onion (allium cepa l) leaf samples were collected from 50 fields and n, p, k, ca, mg, fe, mn, zn, cu and b concentrations were determined. on the bases of yield, the studied fields wer...

The present study was designed to test the hypothesis that in cerebral arteries of the fetus, ATP-sensitive (K(ATP)) and Ca(2+)-activated K(+) channels (K(Ca)) play an important role in the regulation of intracellular Ca(2+) concentration ([Ca(2+)](i)) and that this differs significantly from that of the adult. In main branch middle cerebral arteries (MCA) from near-term fetal ( approximately 1...

scion-rootstock combination and level of salinity affect growth characteristics and concentration of nutrition elements of almond leaves and roots. in this research, effects of salinity stress were investigated on growth characteristics and nutrient concentration of almond leaves and roots by completely randomized design (crd), with two factors, genotype and water salinity with three replicatio...

STIM1 'senses' decreases in endoplasmic reticular (ER) luminal Ca(2+) and induces store-operated Ca(2+) (SOC) entry through plasma membrane Orai channels. The Ca(2+)/calmodulin-activated K(+) channel K(Ca)3.1 (previously known as SK4) has been implicated as an 'amplifier' of the Ca(2+)-release activated Ca(2+) (CRAC) current, especially in T lymphocytes. We have previously shown that human macr...
