The purpose of this study was to identify the prevalence of fungal colonization in water systems and to evaluate the effect of decreasing fungal colonization by a copper-silver ionization system. Environmental samples were collected for fungal culture prospectively during a 1-year period (2011-2012) at the study hospital. A total of 392 water samples were examined from five buildings on March 1...

The present work is an experimental study of steady state convective heat transfer of de-ionized water with a (0.04% by volume) volume fraction of Al2O3 nanoparticles dispersed to form a nanofluid that flows through an aluminium tube.Laminar fully developed flow heat transfer coefficient of Al2O3 nanoparticles are dispersed in water in circular tube is discussed in this paper. In order to valid...

The soluble and ionized calcium and magnesium contents of 18 lots of Mueller-Hinton agar medium from three different manufacturers were analyzed, and the results were correlated with medium performance. A standardized disk diffusion test, with Pseudomonas aeruginosa (ATCC 27853) and a 10-microgram gentamicin disk, served as an indicator of medium performance. Zone diameters correlated well with...

OBJECTIVE To describe the hitherto unrecognized occurrence of transient ionized hypocalcemia with acute adrenal insufficiency and its therapy. METHODS We present three case reports with documented longitudinal laboratory findings. RESULTS Transient ionized hypocalcemia of acute illness has been noted in children and adults and is associated with increased mortality. Precipitating illnesses ...

We studied the stability of ionized calcium and pH in samples stored at either room temperature or 4 degrees C, in centrifuged and uncentrifuged blood-collection tubes and in centrifuged tubes containing a silicone-separator gel (SST tubes). At room temperature, in uncentrifuged blood from healthy individuals, mean ionized calcium usually increased no more than 10 mumol/L per hour; at 4 degrees...

The differentiation between primary or tertiary (both hypercalcemic) and secondary (normocalcemic) hyperparathyroidism requires the identification of hypercalcemia. Calcium in the blood exists as bound, complexed and ionized fractions. Calcium sensors on parathyroid cells interact only with the ionized fraction (about 50% of the total calcium concentration). Many formulas using albumin, total p...

A fully ionized plasma is assumed. T o this plasma cylindrically-symmetric magnetic fields are applied, thus causing a pinch collapse. The plasma is treated in hydromagnetic approximation, including electric and thermal conductivity. Separate temperatures are assigned to the electrons and ions. Two schemes are developed for solving numerically the resulting system of six partial differential eq...

Oxidative damage to DNA, implicated in mutagenesis, aging, and cancer, follows electron loss that generates a radical cation that migrates to a guanine, where it may react with water to form 8-oxo-7,8-dihydroguanine (8-OxoG). Molecular dynamics and ab initio quantum simulations on a B-DNA tetradecamer reveal activated reaction pathways that depend on the local counterion arrangement. The lowest...

BACKGROUND Hypercalcemia is commonly associated with chronic kidney disease (CKD) in cats. OBJECTIVES To explore the calcitonin response to naturally occurring ionized hypercalcemia in cats with azotemic CKD, and to assess the relationship of plasma calcitonin with ionized calcium, alkaline phosphatase (ALP), and urinary calcium excretion. ANIMALS Thirty-three client-owned cats with azotemi...
