BACKGROUND Low serum sodium (Na) has been associated with decreased body mass index and increased cardiovascular mortality in haemodialysis (HD) patients. We examined the relationship between serum Na and selected nutritional parameters of protein energy wasting that are not affected from the hydration status in a cohort of HD patients. METHODS Triceps skinfold thickness (TSF), mid-arm circum...

Genetic traits that confer increased susceptibility to DNA and chromosomal damage from reactive epoxide and peroxides could be important individual risk factors in the development of human cancers. To provide an index of individual sensitivity to expoxides, we previously studied sister chromatid exchange (SCE) induction in peripheral blood lymphocytes and identified a trait involving sensitivit...

Experimental trials of acclimatization of juvenile Persian sturgeon, Acipenser persicus to different salinites of 0,5,10, 15ppt were studied. The juvenile Persian sturgeons in three weight classes (1.5, 3, 5g) have been  transfered from freshwater to different concentrations of saline water.  Na+, k+, Cl- concentrations of blood serum and the changes in the number and size of chloride cells wer...

To the Editor; Tramadol, a synthetic opioid is mainly used to treat acute and chronic pain. Although this drug is not an over-the-counter medication, it has been illicitly accessible to and abused by opium addicts (1-3). Studies showed excessive and widespread use of tramadol in Iran (1-4). Tramadol may cause constipation, drowsiness, tachycardia and respiratory distress, while the most severe...

The Na+ content of poliovirus-infected HeLa S3 cells increased during the late phase of virus replication, after virus inhibition of host cell protein synthesis and in coincidence with late viral functions. Guanidine hydrochloride blocked the rise in Na+ content, whereas the antiguanidine agent choline fully reversed the guanidine block. Expression of one or more late viral functions was essent...

matricaria chamomilla is a medicinal plant that is widely cultivated in salt affected soils. this investigation was undertaken to study the effect of nacl concentration on germination, and the physiological, biochemical and growth characteristics of chamomile. seed germination and growth were studied at five nacl concentration levels (0, 40, 80, 120 and 190 mm nacl concentration). increasing th...

New fluorescent Na+ indicators, SBFI (short for sodium-binding benzofuran isophthalate) and SBFP (short for sodium-binding benzofuran phthalate) (Minta, A., and Tsien, R. Y. (1989) J. Biol. Chem. 264, 19449-19457), were tested in Jurkat tumor lymphocytes and in REF52 rat embryo fibroblasts. Both dyes could be introduced by direct microinjection. However, when cells were incubated with the tetra...

A gel filtration fraction of serum from chronically uremic patients has been shown previously to produce natriuresis in the rat. In the present studies, the same fraction from urine of uremic patients and normal subjects was studied for its natriuretic activity. Urine samples were obtained from 17 chronically uremic patients (mean glomerular filtration rate [GFR], 8.7 ml/min; mean fractional so...

BACKGROUND Drug-eluting balloons (DEB) may reduce infrapopliteal restenosis and reintervention rates versus percutaneous transluminal angioplasty (PTA) and improve wound healing/limb preservation. OBJECTIVES The goal of this clinical trial was to assess the efficacy and safety of IN.PACT Amphirion drug-eluting balloons (IA-DEB) compared to PTA for infrapopliteal arterial revascularization in ...

Bullfrog sympathetic ganglion cells were capable of producing action potentials (Ca spikes) in an isotonic (84 mM) CaCl2 solution. The peak level of Ca spikes showed an approximately 30 mv increase with a 10-fold increase in the Ca concentration. Na as well as Ca ions were capable of acting as charge carriers during the production of action potentials in a solution containing relatively high Ca...
