the effects of fish weight on salinity tolerance were studied in caspian salmon (salmo trutta caspius) parr. 180 fish (all with 2 years old but with three weights; 5, 15, 25g) were selected and they reared in freshwater (fw) and brackish water (bw; 13ppt salinity) for 10 days. the mrna expression of two α-subunit isoforms of na+, k+-atpase (α1a and α1b) and nkcc co-transporters were studied in ...

objective(s): recently, phthalimide derivatives were designed based on ameltolide and thalidomide as they possess a similar degree of anticonvulsant potency due to their phenytoin-like profile. the ability of phthalimide pharmacophore to interact with neuronal voltage-dependent sodium channels was studied in the batrachotoxin affinity assay. therefore, in the present study, a series of 19 compo...

Aplikácia simulačných modelov pre optimalizáciu zložení uholných zmesí V prostrediu trhovej ekonomiky sú kladené zvlášť vysoké požiadavky na riadenie výrobných technológií v oblasti uholných hlbinných baní (ťažba, odťaženie, apod.) z hľadiska dosiahnutia čo najlepších ekonomických parametrov ( produktivita práce, zisk, rentabilita). Jednou z možností ich zlepšení je aj užitie metód selektívnej ...

An investigation of Vemo Herb® additive on the forage consumption rate in Japanese quail (Pharaoh breed) has been conducted. The experiment was carried out for 10 weeks with 52 female and 16 male sexually matured Japanese quails (Coturnix coturnix japonica) distributed in four groups: control group (without additive), first experimental group 4 mg*kg of live weight for 10 weeks; second experime...

Red blood cell Li-Na countertransport and Na-K cotransport activities, home blood pressure, invasive systemic hemodynamics, and limb venous compliance were measured in 65 white men (23 normotensive, 22 borderline hypertensive, and 20 mild essential hypertensive subjects). Li-Na countertransport activity was positively and significantly correlated with subject-determined home systolic blood pres...

The East Lau Spreading Center (ELSC) and Valu Fa Ridge (VFR) comprise a ridge segment in the southwest Pacific Ocean where rapid transitions in the underlying mantle chemistry manifest themselves as gradients in seafloor rock geochemistry. We studied the geology and microbial diversity of three silicate rock samples and three inactive sulfide chimney samples collected, from north to south, at t...

vacuolar h+-translocation pyrophosphatase (v-ppase) and na+/h+ antiporter (v-na+/h+) are important transporters in plant cells and have essential roles against abiotic stresses. in this study, the effects of salt stress were surveyed on the transcription of v-ppase pump and na+/h+ antiporter genes at early times of nacl treatment in roots of halophytic grass leptochloa fusca through the real ti...

thermal behavior of various solid feldspars are different, namely those of bivalent cations show no change in the distribution of al and si atoms, whereas feldspars of univalent cations become more disordered with raising temperature. in the latter case al atoms migrate from the sites they occupe at low temperatures and interchange positions with the si atoms. at high temperatures (but still be...
