Background: Abnormality of hepatic vein (HV) waveform evaluated by Doppler ultrasonography has been widely studied in patients with chronic liver disease. The paper investigates the relationship between HV waveform changes, portal vein velocity (PVVel), hepatic artery pulsatility index (HAPI) and portal pressure (PP) measured directly from patients with portal hypertension (PHT), aiming to disc...

Four metabolism and two finishing trials were conducted to determine the effects of imposed feed intake variation on acidosis and performance of finishing steers. In Metabolism Trial 1, four ruminally fistulated steers were limit-fed and subjected to either a constant amount of feed per day (C) or low intake variation of .7 kg/d (LV). No treatment differences were found for intake or measures o...

This study aimed at identifying the performance of Family Health Strategy (FHS) nurses in home care. It consists of an exploratory descriptive study using a qualitative approach. Six FHS nurses from a health district of Porto Alegre, Rio Grande do Sul, Brazil, were interviewed. Data were submitted to thematic content analysis, revealing three categories: home visit (HV) in the FHS, assessment o...

Hidden-variable (HV) theories allege that a quantum state describes an ensemble of systems distinguished by the values of hidden variables. No-go theorems assert that HV theories cannot match the predictions of quantum theory. The present work started with repairing aws in the literature on no-go theorems asserting that HV theories cannot predict the expectation values of measurements. That lit...

High tidal volume (HV(T)) ventilation causes pulmonary endothelial barrier dysfunction. HV(T) ventilation also increases lung nitric oxide (NO) and cGMP. NO contributes to HV(T) lung injury, but the role of cGMP is unknown. In the current study, ventilation of isolated C57BL/6 mouse lungs increased perfusate cGMP as a function of V(T). Ventilation with 20 ml/kg V(T) for 80 min increased the fil...

BACKGROUND Few studies have investigated the safe limits of contrast to prevent contrast-induced nephropathy (CIN) based on hydration data. We aimed to investigate the relative safe maximum contrast volume adjusted for hydration volume in a population with a relatively low risk of CIN. METHODS AND RESULTS The ratios of contrast volume-to-creatinine clearance (V/CrCl) and hydration volume to b...
