BACKGROUND Previous studies that reported an association of dietary Na(+) intake with metabolic syndrome were limited by the use of imprecise measures of obesity, Na(+) intake, or exclusion of multiethnic populations. The effect of dietary K(+) intake on obesity is less well described. OBJECTIVE We hypothesized that high dietary Na(+) and low K(+), based on the ratio of urinary Na(+) to K(+) ...

BACKGROUND A high ablation success rate for ventricular arrhythmia (VA) from outflow tract has been achieved, but some of them cannot be eliminated from endocardium. We investigated the association between adenosine sensitivity and ablation success/recurrence rates with a nonirrigated or an irrigated catheter. METHODS According to adenosine test, all patients were divided into a sensitive gro...

The role of oxidative stress in the long-term regulation of arterial pressure, renal hemodynamics, and renal damage was studied in Dahl salt-sensitive rats. Twenty-eight Dahl S/Rapp strain rats, equipped with indwelling arterial and venous catheters, were subjected to a 3-week intravenous infusion of either low Na (0.9 mmol/d) or high Na (20.6 mmol/d) or the superoxide dismutase mimetic, 4-hydr...

in this research, the groundwater quality of hoz–e–soltan lake and its catchment was studied for drinking, domestic and irrigation uses according to different parameters. this lake with 195 km2 catchment area is located 85 km of southwest of tehran–qom highway. in order to investigate groundwater quality characteristics in the study area, 34 data from water of well belong to 2008 selected to pr...

This study was performed to investigate the distribution characteristics of airborne bacteria emitted from swine manure composting plants. The types plants selected for survey in this were as follows: screw type, rotary and natural dry type. Mean levels 7428 (±1024) CFU m−3 3246 (±1407) 5232 (±1217) respectively. Based on results obtained study, plant operated by type showed highest concentrati...

The title compound, sodium disilver arsenatotrimolybdate, Na(0.93 (1))Ag(2.07 (1))Mo(3)AsO(13), was prepared by a solid-state reaction. In the crystal structure, isolated AsO(4) tetra-hedra share corners with groups of three edge-sharing MoO(6) octa-hedra. This arrangement leads to the formation of anionic (1) (∞)[Mo(3)AsO(13)](n) ribbons extending parallel to [100]. The three metal sites show ...

Given the potential clinical benefit of inhibiting Na+/Ca2+ exchanger (NCX) activity during myocardial ischemia reperfusion (I/R), pharmacological approaches have been pursued to both inhibit and clarify the importance of this exchanger. SEA0400 was reported to have a potent NCX selectivity. Thus, we examined the effect of SEA0400 on NCX currents and I/R induced intracellular Ca2+ overload in m...

A total of 150 Hy-Line W-36 laying hens at 38 week of age were randomly assigned into 5 dietary treatments and 3 replicates each with 10 birds. Hens were fed diets including: low-selenium diet without selenium supplementation (basal diet), basal diet plus 0.3 ppm Na-selenite, or basal diet plus 0.1, 0.2 and 0.3 ppm Sel-Plex. The hens performance, eggshell quality and egg selenium content were e...

Changes in the number of Na+-K+-ATPase alpha-subunits, Na+-K+-ATPase activity and glycogen content of the crucian carp (Carassius carassius) brain were examined to elucidate relative roles of energy demand and supply in adaptation to seasonal anoxia. Fish were collected monthly around the year from the wild for immediate laboratory assays. Equilibrium dissociation constant and Hill coefficient ...
