BACKGROUND AND OBJECTIVES The amount of metabolic acidosis measured through the standard base excess (SBE) has been shown to be an outcome marker and its improvement has been associated with better survival. We studied the mechanism of standard base excess variation in the first three days of intensive care unit (ICU) stay through the evaluation of independent variables of physico-chemical appr...

UNLABELLED We compared estimates for base excess of extracellular fluid (BE(ecf); mmol/L) obtained in five clinically used blood gas analyzers: AVL Compact 2 (Roche Diagnostics, Mannheim, Germany), Ciba-Corning 860 (Bayer Diagnostics, Fernwald, Germany), IL 1620 (Instrumentation Laboratories, Lexington, MA), Stat Profile Ultra (Nova Biomedical, Waltham, MA), and ABL 510 (Radiometer, Copenhagen,...

BACKGROUND Animal models are necessary to study the mechanism underlying the effects of exercise on depression but an effective procedure for exercise treatment and exercise effects on physiological parameters in a specific depression model need to be characterized. METHODS Physiological parameters including lactate, partial pressue of O₂ (pO₂) and CO₂ (pCO₂) saturated O₂ (sO₂), pH, HCO₃, tot...

PURPOSE To examine the effect of beta-alanine only and beta-alanine with sodium bicarbonate supplementation on 2,000-m rowing performance. METHODS Twenty well-trained rowers (age 23 ± 4 y; height 1.85 ± 0.08 m; body mass 82.5 ± 8.9 kg) were assigned to either a placebo or beta-alanine (6.4 g · d(-1) for 4 weeks) group. A 2,000-m rowing time trial (TT) was performed before supplementation (Bas...

for assessment of portfolio performance, it's crucial to adjust the return by the risk which is taken. so it seems undeniable that for measuring the risk-adjusted return of portfolio, we need an appropriate and developed model for risk and asset pricing. fama & french 3 factor model could explain several return anomalies. recent studies show that capital productivity effects on stock retur...

Sodium heparin solution is widely used as an anticoagulant in blood gas analysis. Although alterations in blood gas measureIf heparin makes up 10% or more of the t ments may occur when small sample volumes are diluted by volume of a sample for blood gas anal. heparin,' 2 such errors are generally thought to be of theoretical important errors in the carbon dioxide pressi rather than practical im...

This paper examines the issues of excess volatility and excess comovement of interest rates among global bond markets. The base model of interest rate behavior is the expectations theory of the term structure. The empirical evidence presented in the paper indicates that 10-year government bond yields in five major markets—the United States, Japan, Germany, the United Kingdom and Canada—have in ...

PURPOSE To compare the evolution of standard base excess and serum lactate level between surviving and non surviving patients with severe sepsis and septic shock resuscitated with early goal-directed therapy. METHODS This is a retrospective study in an intensive care unit of a university tertiary hospital where 65 consecutive severe sepsis and septic shock patients were observed without any i...

BACKGROUND AND OBJECTIVES To correlate standard base excess (SBE) with serum lactate level and demonstrate the independent prognostic significance of each one. METHODS In a retrospective study, we retrieved data from 333 patients of our prospectively collected database of 7-bed medical intensive care unit of a 1800-bed university hospital. RESULTS The results have shown a poor correlation b...

A comparison between 2 dilute citrate solutions (15mmol/l vs 18 mmol/l) in continuous renal replacement therapy: the base excess and renal replacement solution (BEARRS) study
