Background & Aims: Nanosilver-based paint is a new technology with antimicrobial and antifungal characteristics. These characteristics were investigated in this study with regard to fungal contamination in hospitals. Method: Regarding hospitalization of transplant patients and their sensitivity to hospital infections, two similar rooms were selected in nephrology ward. One of them was paint...
The objective of the study was to evaluate the detection efficiency of micro-vacuum surface sampling and surface wet wipe sampling in homes that had been identified with vermiculite attic insulation and/or other asbestos containing materials. Surface samples were collected pre and post weatherization activities and analyzed by transmission electron microscopy. Baseline sampling revealed that we...
Abstract: Researchers concerned to the related historical textiles are protection and cleaning. Because of the influence of this construction and structure, knowledge base, contamination and methods to deal with it is of utmost importance. In this regard, many researchers have studied, identified, classified and introduced the contamination on textile history. But for reverse enginee...
Aim e purpose of this study was to compare surface contamination resulting from standard syringe plungers and cylinders compared to using the EQUASHIELD® Syringe Unit. Method e contamination level of standard syringes was compared to that of EQUASHIELD® Syringe Units, after repeated pharmaceutical manipulations using an antineoplastic (Cyclophosphamide) drug. Results Signi cant levels of up to ...
plasma-sprayed silicon layers have been used to produce silicon nitride layers with fibrous microstructure which optimizes fracture toughness and strength. SEM examination of the specimens shows that the surface is covered by fine needles and whiskers of Si3N4.In order to study the oxygen contamination effect as well as other contaminants introduced during spraying and nitridation processes, su...
Background and Objective: Heavy metals are the most frequent pollutants of urban soils. In general, human health and especially children are directly at risk if the soil is being accidentally ingested orally or nasally. Therefore, this study was conducted to assess potential ecological risk index (RI) of Pb, Cd, Cr and Cu in surface soils of urban parks in Tehran City in 2016. Materials and Me...
An academic subcommittee of Japanese Society of Hospital Pharmacists formulated the guideline for the sterile preparation of antineoplastic agents in 2008. The practical methods to monitor a workplace contamination and occupational exposure to antineoplastic agents have not been introduced into a hospital setting yet. The aims of this study were to develop a monitoring method using doxorubicin ...
objective: infection control is one of the important aspects in dentistry. oral and maxillofacial surgery is one of the most sensitive fields in dentistry in which infection control is important a sterile surgical set is imperative. manufacturers only guarantee the sterility of the anesthetic not the sterility of its outer surface. they recommend alcohol to sterile the outer surface (especially...
