The survival of Staphylococcus aureus was determined from inoculated swatches laundered in either a phosphate or a phosphate-substitute detergent. In a Plackett-Burman design study, the independent variables of detergent type, concentration, and variation, wash water temperature, soil load, cycle time, and water hardness were assigned high and low values. Wash water temperatures of 27, 38, 49, ...

meningitis is an inflammation of the membranes that surround the brain and spinal cord, thereby involving the arachnoid, the pia and the cerebrospinal fluid (csf). it is divided into viral and bacterial meningitis. for different reasons the diagnosis of bacterial meningitis is very important. the examination of csf samples may provide information about causative microorganism. the sensivity of ...

introduction: favorable apical seal of root filling materials is a crucial factor for a successful root canal treatment. the aim of this in vitro study was to compare bacterial and dye microleakage of two root canal filling materials including standard gutta-percha and nanosilver coated gutta-percha, and to evaluate the agreement between results of these two methods . materials & methods: fifty...

from 1986 to 1996, 1020 renal transplants were performed at our center. the purposes of this study were. 1) to evaluate the patient and graft survival rates and 2) to see if some donors and recipient characteristics such as age, sex and relationship had any effects on graft survivals. 571 transplants were from living related donors (lrd) and 446 from living unrelated donors (lud). 65.9% of reci...

background: breast cancer arising in young patients (≤ 40 years) is being considered as a distinct clinical entity with more aggressive tumor features and poorer survival. our aim was to assess the impact of age on survival among a large group of iranian women diagnosed with breast cancer. methods: in a cross-sectional study, demographic and clinicopathological characteristics of patients with ...

Dispersal of species is a fundamental ecological process in the evolution and maintenance of biodiversity. Limited control over ecological parameters has hindered progress in understanding of what enables species to colonize new areas, as well as the importance of interspecies interactions. Such control is necessary to construct reliable mathematical models of ecosystems. In our work, we studie...

Staphylococcus aureus expresses a panel of cell wall-anchored adhesins, including proteins belonging to the microbial surface components recognizing adhesive matrix molecule (MSCRAMM) family, exemplified by the serine-aspartate repeat protein D (SdrD), which serve key roles in colonization and infection. Deletion of sdrD from S. aureus subsp. aureus strain NCTC8325-4 attenuated bacterial surviv...

The use of juvenile Artemia as feed in aquaculture and in the pet shop industry has been getting more attention during the last decade. In this study, the use of selected bacterial strains to improve the nutritional value of dry food for Artemia juveniles and to obtain control of the associated microbial community was examined. Nine bacterial strains were selected based on their positive effect...
