ribosomal proteins and @ H-labeled growing chains were mixed and dually counted after fractionation by different techniques. Ehrlich adenocarcinoma ascites cells were taken from mice (Swiss strain) inoculated 6 days earlier. The cells were separated from the ascitic plasma by centrifugation at 500 X g for S mm and washed once with 3 volumes of a medium containing NaC1 (0.12 M), KC1 (13 mM), MgS...

Obstructive sleep apnoea syndrome (OSAS) might be a cause of heart failure. The present study aimed to assess left ventricular mass and myocardial performance index (MPI) in OSAS patients. A total of 67 subjects without any cardiac or pulmonary disease, referred for evaluation of OSAS, had overnight polysomnography and echocardiography. According to apnoea-hypopnoea index (AHI), subjects were c...

Overland and shallow subsurface hydrologic transport of pathogenic Cryptosporidium parvum oocysts from cattle feces into surface drinking water supplies is a major concern on annual grasslands in California's central and southern Sierra Nevada foothills. Soil boxes (0.5 m wide x 1.1 m long x 0.3 m deep) were used to evaluate the ability of grass vegetated buffer strips to retain 2 x 10(8) spike...

The aim of this study was to investigate the effect of small alterations in the extracellular magnesium concentration on the tone of feline middle cerebral arteries and to examine the role of the endothelium in these responses. We measured the isometric tension of isolated arterial rings placed between two stainless steel wires in a tissue chamber containing Krebs-Henseleit solution aerated wit...

In helically cut strips of dog cerebral, coronary, mesenteric and femoral arteries, the contractile response to prostaglandin (PG) F2alpha, and E2, relative to contractions induced by 30 mM K+, did not appreciably differ, whereas relaxations induced by PGE1 relative to those induced by 10(-4) M papaverine were significantly different; the least in cerebral arteries and the greatest in mesenteri...

The effects of tiropramide hydrochloride on Ca(2+)-induced contraction, cytoplasmic free Ca2+ levels and tissue cyclic AMP concentrations were investigated to elucidate the mechanisms of its antispasmodic action in the isolated detrusor from rats. Tiropramide inhibited the Ca2+ (3 mM)-induced contractions of the isolated urinary bladder depolarized in a Ca(2+)-free medium, and the IC50 value wa...

X X Ž X . The phosphorylation of inosine in the 5 -position to produce inosine-5 -monophosphate 5 -IMP was studied in a number Ž . of microorganisms from our culture collection using pyrophosphate PPi as the phosphate source. Although many of the microorganisms screened were able to phosphorylate inosine, phosphotransferase activity specific to the 5-position was found to be distributed among t...
