Thirty-seven patients with liver cirrhosis (16 without ascites: group 1; 21 with untreated ascites at the first onset: group 2) were studied during controlled sodium intake (40 mmol/day). Renal plasma flow, glomerular filtration rate, urinary sodium excretion, plasma sodium and potassium, plasma renin activity, plasma aldosterone concentration, blood volume, and arterial pressure were evaluated...

To study the dynamics of liquid gastric emptying in rhesus monkeys under conditions that simulated gastric fill during a meal, we measured the gastric emptying of liquid glucose at various concentrations and volumes when administered intragastrically at rates ranging from 12.5 to 37.5 ml/min. Glucose gastric emptying was faster during than following the period of gastric fill. At a single gluco...

BACKGROUND It is common clinical practice to use fluid infusion to manage high-volume blood loss until a blood transfusion is performed. The authors investigated the influence of fluid infusion associated with blood loss on the pseudo-steady state propofol concentration. METHODS Twenty-seven swine were assigned to a lactated Ringer's solution group, a hydroxyethyl starch group, or a threefold...

BACKGROUND Large-volume hepatic radiofrequency ablation (RFA) has been used to treat large liver tumors, but its safety limit is unknown. This study aimed to investigate the possible systemic responses of large-volume hepatic RFA and to estimate its safety limit in normal and cirrhotic rats. HYPOTHESIS Large-volume hepatic RFA causes a significant systemic inflammatory reaction. DESIGN Expe...

in the present work the effect of cu-water nanofluid, as heat transfer fluid, on the performance of a parabolic solar collector was studied numerically. the temperature field, thermal efficiency, mean-outlet temperatures have been evaluated and compared for the conventional parabolic collectors and nanofluid based collectors. further, the effect of various parameters such as fluid velocity, vol...

ABSTRACT- Titanium is a beneficial element for plant since its promotive effect on plant metabolism has been well documented. However, the physiological role of this trace element in tomato is not clear. This experiment was conducted as a complete randomized design to study two concentrations of titanium (1 and 2 mg/L Ti) and 0 as control on physiological and nutrient properties of tomato cv. F...

The aim of the present study was to determine seasonal variations in semen characteristics, testicular size, and plasma testosterone concentration in Iranian Khalkhali goats. An artificial vagina was used to collect semen from 10 bucks (2–4 years of age), from November 2013 to October 2014. Testicular circumference was higher (P<0.05) from September to October. Ejaculate volume, sperm ...

introduction: antibiotics have the potential to adversely affect the microbial community. for anaerobic digestion, a sufficient methanogenic population needs to be preserved in the system. the main aim of this study was determination of inhibitory concentration of oxytetracycline on methanogenic bacteria. methods: a 120 ml jacketed bioreactor with a 90 ml working volume was inoculated granular ...

This study was aimed at determining the blood serum testosterone level and its relationship with scrotal circumference and physical characteristics of semen in Nili-Ravi buffalo bulls. Semen samples were collected weekly from three buffalo bulls of 14 years age for 12 weeks and were evaluated for physical characteristics i.e. ejaculatory volume, sperm motility, sperm concentration, pH and sperm...
