OBJECTIVES To test whether hydration with bicarbonate rather than isotonic sodium chloride reduces the risk of contrast-associated acute kidney injury in critically ill patients. DESIGN Prospective, double-blind, multicenter, randomized controlled study. SETTING Three French ICUs. PATIENTS Critically ill patients with stable renal function (n = 307) who received intravascular contrast med...
Acute renal dysfunction after radiocontrast in patients with pre-existing renal impairment is not uncommon and is associated with significant morbidity and mortality. Isotonic sodium bicarbonate solution was first reported to reduce radiocontrast nephropathy in 2004. This first study was, however; limited by its small sample size and as such, the use of isotonic sodium bicarbonate to prevent ra...
Background and purpose: Pesticide residues in food products is of great concern. Food preparation highly influences the pesticide residue and safety of the food. The aim of this study was to evaluate the effects of storage and different washing solutions on dichlorvos residue in tomato. Materials and methods: A Interventional study was performed in which tomato samples were harvested after 2...
The present work aims to assess the water quality index (WQI) of Manyad Storage tank, Aurangabad district, Maharashtra, India. surface sample were assessed for physico-chemical parameters namely pH, Electrical Conductivity, Total Dissolved Solid, Hardness, Bicarbonate, Chlorides, Sulphates, Nitrates, Calcium, Magnesium, Sodium, Potassium and Fluoride in post-monsoon season 2020. For calculating...
The present studies were designed to characterize sodium transport in the jejunum and ileum of humans with respect to the effects of water flow, sodium concentration, addition of glucose and galactose, and variations in aniomic composition of luminal fluid. In the ileum, sodium absorption occurred against very steep electrochemical gradients (110 mEq/liter, 5-15 mv), was unaffected by the rate ...
OBJECTIVE This study evaluates the effect of early administration of an empirical (1 mEq/kg) sodium bicarbonate dose on survival from prehospital cardiac arrest within brief (<5 minutes), moderate (5-15 minutes), and prolonged (>15 minutes) down time. METHODS Prospective randomized, double-blinded clinical intervention trial that enrolled 874 prehospital cardiopulmonary arrest patients manage...
The effect of intravenous vasoactive intestinal polypeptide (VIP) on normal transport mechanisms in the human jejunum in vivo was examined with the triple-lumen, steady-state perfusion technique. By using special test solutions that revealed different aspects of jejunal transport, we were able to evaluate the effect of VIP on specific transport processes, such as active bicarbonate absorption, ...
Objective(s) Motility plays a major role in pathogenicity of Helicobacter pylori, yet there is scarce data regarding its chemotactic behaviour. The present study was designed to investigate the chemotactic responses of local isolates of H. pylori towards various sugars, amino acids, as well as some other chemical substances. Materials and Methods Chemotaxis was assayed by a modified Adler’s...
It recently has been shown that whole cell calcium and sodium currents are modulated by CO(2)/HCO(3)(-)-buffered saline. While the bicarbonate ion, but not CO(2), has been proven to modulate calcium currents, this information is lacking for sodium currents. Furthermore, it is not known whether the strength of modulation dependents on the bicarbonate concentration or whether it is an all-or-noth...
In this quasi-experimental study, we assess the effect of sodium bicarbonate solution on onset and duration of anesthesia with the use of lidocaine and adrenaline solution in surgical patients undergoing epidural anesthesia
