Objective To provide a clinically relevant overview of the analytical interference by contrast agents (CA) in laboratory blood test measurements. Materials and Methods The effects of five CAs, gadobutrol, gadoterate meglumine, gadoxetate disodium, iodixanol, and iomeprol, were studied on the 29 most frequently performed biochemical assays. One-day-old plasma, serum, and whole blood were spike...

From 8 to 15 mM of strong mineral acid per kilogram of body weight may be infused intravenously in the dog over a period of a few hours to produce a severe but non-fatal acidosis. Van Slyke and Cullen (1) showed that only one-sixth of the infused acid is neutralized by blood buffers, five-sixths presumably being neutralized by bicarbonate in interstitial fluid and lymph and by intracellular pho...

The present studies examined the effect of acute in vitro acidosis on chloride reabsorption in the rabbit cortical thick ascending limb of Henle (cTALH). Four protocols were used: hypercapnic acidosis; "isocapnic" peritubular acidosis (bath bicarbonate reduction to 10 mM); isocapnic luminal acidosis (luminal bicarbonate reduction to 10 mM); isocapnic peritubular acidosis in the absence of lumin...

BACKGROUND Bumble bees [Bombus impatiens (Cresson)] are widely used for supplemental pollination of greenhouse vegetables and are at risk of pesticide exposure while foraging. The objective of this study was to determine the lethal and sub-lethal effects of four insecticides (imidacloprid, abamectin, metaflumizone and chlorantraniliprole) and three fungicides (myclobutanil, potassium bicarbonat...

To investigate the physiological adjustments of textile workers exposed to high temperature environment, 10 workers with years of work experience and 12 students with rarely entering into workshop were chose to a hospital for blood test and nerve conduction velocity measurements. The blood test was to measure potassium content, sodium content, calcium content and bicarbonate content in particip...

Cryptosporidium parvum oocysts were examined to ascertain excystation requirements and the effects of gamma irradiation. Oocysts and excysted sporozoites were examined for dye permeability and infectivity. Maximum excystation occurred when oocysts were pretreated with acid and incubated with bile salts, and potassium or sodium bicarbonate. Pretreatment with Hanks' balanced salt solution or NaCl...

Hydrological status and water table fluctuations are directly related to land use and/or land cover (LULC) changes in each area. In this research, the impact of LULC changes on groundwater quantity and quality of Khan-Mirza Plain, in the northern Karun watersheds, was investigated. For this purpose, Landsat 5, 7 and 8 satellite images and ETM and OLI sensors were employed to prepare the L...

BACKGROUND This study aimed to observe the effect of hemoperfusion (HP) cartridge on different internal environment indicators at different time points in patients with acute blood poisoning and to find alternative indicators for the detection of blood poisoning. METHODS The levels of internal environment indicators (blood pH, PvCO2, PvO2, blood lactate, potassium, free calcium, bicarbonate, ...

Steady-state rates of potassium ion and sodium ion absorption by excised barley roots accompanied by various anions were compared with the rates of anion absorption and the concomitant H(+) and base release by the roots. The cation absorption rates were found to be independent of the identities, concentrations, and rates of absorption of the anions of the external solution, including bicarbonat...

ROTHMAN, S. S., AND F. P. BROOKS. Electrolyte secretion from rabbit pancreas in vitro. Am. J. Physiol. 208(6) : I 171-1176. 1965. -A technic has been developed permitting direct collection of undiluted rabbit pancreatic secretion in vitro without vascular perfusion. The rates of secretion and output of electrolytes were comparable to those obtained in situ. When secretin was added, flow and bic...
