Background and Objectives: According to hazardous infection possibility in patients with a weakened immune system, old adults, and children, microbial contamination in the waterlines of dental units has become a recent concern. The aim of the present study was to evaluate the microbial contamination in dental unit waterlines in the School of Dentistry, Qom University of Medical Sciences, Qom, I...
Background and purpose: Occlusion is a decreasing factor on longevity of peripheral intravenous catheters (PIVCs). Continuous flushing (injection of specific volume of solution such as Normal Saline (N/S) before and after each drug infusion into PIVCs at determined interval time) is one of the effective methods in in vitro studies to maintain the PIVCs patency. The aim of this study was to inve...
To test the suggestion that chlorpropamide-alcohol flushing (CPAF) resembles the disulfiram effect and might be mediated by acetaldehyde, the initial metabolite of alcohol, blood concentrations of acetaldehyde were measured after a drink of alcohol in controls and diabetics positive and negative for CPAF. The CPAF-positive diabetics had significantly greater blood acetaldehyde concentrations af...
BACKGROUND Long-term tunnelled central venous catheters (TCVCs) are increasingly used when treating oncology patients. Despite international guidelines on sterile insertion, appropriate catheter maintenance and use, infections still a complication of TCVC. These infections are mainly caused by Gram-positive bacteria. Antimicrobial prevention strategies aimed at these micro-organisms could poten...
abstract this study aimed at investigating the possible relationship between self-assessment in writing and self-regulation of iranian efl learners. the main purpose of the study was not only to report and inform about this relationship, but also to investigate and find practical outcomes of the incorporation of self-assessment in writing, such as improving writing skill. the research was carr...
BACKGROUND Epidural steroid injections are commonly used in managing radicular pain. Most complications related to epidural injections are minor and self-limited. Flushing is considered as one such minor side effect. Flushing has been studied using various steroid preparations including methylprednisone, triamcinolone, and betamethasone but its frequency has never been studied using dexamethaso...
A dehydrogenase is an enzyme responsible for the breakdown of acetaldehyde, a toxic intermediate1 produced directly from the metabolism of alcohol. Aldehyde dehydrogenase is extraordinarily efficient in keeping acetaldehyde levels very low, even immediately after alcohol consumption when acetaldehyde is being generated rapidly in the liver. Multiple aldehyde dehydrogenase enzymes exist and thei...
The reproductive performance of postpartum cows is affected by factors such as suckling and nutrition. We investigated the effect of a restricted suckling period on the superovulatory response and the fertility after flushing in postpartum Japanese Black cows. Forty-seven postpartum cows were used in this study. At 7 days postpartum, the cows were divided into 2 groups: (1) continuous access to...
A modelling methodology using a leachate source term has been produced for estimating the timescales for achieving environmental equilibrium status for landfilled waste. Results are reported as the period of active management required for modelled scenarios of non-flushed and flushed sites for a range of pre-filling treatments. The base scenario against which results were evaluated was raw muni...
