Each of 28 Vibrio strains and 3 Campylobacter strains was immobilized in distilled water (pH 6.9), but retained full motility in Trypticase soy broth. This phenomenon was not seen with any of 243 non-Vibrio, non-Campylobacter isolates representing 44 taxa of gram-negative bacteria.

AIM A role of thyroid disruption in developmental neurotoxicity of monocrotophos (MCP) and lead is studied. MATERIALS AND METHODS A total of 24 female rats after conception were randomized into four groups of six each and treated as follows: Group I - Sham was administered distilled water orally. Group II - A positive control was administered methyl methimazole at 0.02% orally in drinking wat...

BACKGROUND Hawthorn species decreases blood pressure and relaxes precontracted vessels. This study aimed at examining the antihypertensive effect and related mechanisms of hydroalcoholic extract of Crataegus azarolus subspecies aronia fruit in rats with renovascular hypertension. METHODS Six groups of male Sprague-Dawley rats, each containing 6 to 8 rats, were studied. The groups comprised of...

in this paper, overall heat transfer coefficient and friction factor of water based γ-al2o3 nanofluid in a double tube counter flow heat exchanger have been measured experimentally under turbulent flow condition. for better dispersion of γ-al2o3 nanoparticles in distilled water, magnetic stirrer and ultrasonic vibrator (with a power of 240 kw and frequency of 35 khz) were implemented. the stabi...

Decimal reduction values (D value) for 30 viruses were determined. The weighted D values of the viruses suspended in Eagle's minimum essential medium ranged from 0.39 to 0.53 Mrads. It was necessary to increase the radiation dose by a factor of >3 to inactivate virus suspended in Eagle's minimum essential medium as compared to the same virus suspended in distilled water. The destruction rate cu...

Laryngeal chemoreflexes (LCR) are triggered by the contact of assorted liquids with the laryngeal mucosa. In the neonatal period, the immature LCR consist primarily of apnea and bradycardia, which at times can be life threatening. The aim of this study was to assess LCR induction in nonsedated, newborn full-term lambs by several acid solutions, compared with distilled water and saline. Twelve l...

Pseudomonas cepacia strains were isolated from the water reservoirs of unheated nebulizers in a hospital setting. The isolates were characterized by morphology, biochemical tests, and antibiotic susceptibility patterns. An interesting feature of these organisms was their capacity for sustained multiplication in either doubly deionized or doubly distilled water as well as 5% dextrose or 0.9% sal...

The dye reagent is buffered by M/10 phosphate salts at pH 7.4 and is prepared by dissolving 12.07 gm. anhydrous disodium hydrogen phosphate powder, 2.04 gm. potassium dihydrogen phosphate crystals, 2.60 gm. sodium arsenite powder, and 2.10 gm. sodium fluoride powder in 1 L. of distilled water. Sufficient 2,6-dichlorobenzenoneindophenol sodium is added to bring the absorbance of the solution to ...

A study was conducted to evaluate the efficacy of electrolyzed acidic water, 200-ppm chlorine water, and sterile distilled water in killing Escherichia coli O157:H7, Salmonella, and Listeria monocytogenes on the surfaces of spot-inoculated tomatoes. Inoculated tomatoes were sprayed with electrolyzed acidic water, 200-ppm chlorine water, and sterile distilled water (control) and rubbed by hand f...

introduction: sealing ability of root-end filling materials is of great importance. it can be investigated by measuring microleakage. the purpose of this in vitro study was to evaluate microleakage of calcium enriched mixture (cem) cement in two different media including phosphate buffer solution (pbs) and distilled water. materials and methods: twenty single-rooted human teeth were selected. a...
