OBJECTIVES We investigated vancomycin-intermediate Staphylococcus aureus (VISA) and heterogeneously vancomycin-intermediate S. aureus (hetero-VISA) isolates from clinical specimens of hospitalized patients at Hacettepe University over a 4 year period. METHODS Strains were screened for VISA and hetero-VISA by using brain heart infusion agar containing 4 mg/L vancomycin (BHI-V4) and macro Etest...

Bearings are widely used in various industries to support rotating shafts. Their failures accelerate failures of other adjacent components and may cause unexpected machine breakdowns. In recent years, nonlinear vibration responses collected from a dynamic rotor-bearing system have been widely analyzed for bearing diagnostics. Numerous methods have been proposed to identify different bearing fau...

Epidemiological studies have suggested a pathophysiological link between obstructive sleep apnea syndrome (OSAS) and Alzheimer's disease (AD). The mechanism by which sleep disturbance can affect cognitive impairment is not clear. The aim of this study was to investigate whether AD patients with OSAS have an impairment in cerebrovascular disease markers. We included 69 patients without OSAS and ...

OBJECTIVE The objective of the study was to compare premixed insulin aspart 30 (BIAsp 30) vs premixed human insulin 30 (BHI 30) on efficacy, safety, fetal and perinatal outcomes in pregnancies associated with gestational diabetes mellitus [GDM]. This was the first randomized study to use pre mixed insulin analogue [BIAsp] in GDM. METHODS The study population consisted of 76 GDM women assigned...

BACKGROUND AND PURPOSE The aim of this study was to explore the possible contribution of alterations in cerebral hemodynamics to the evolution of cognitive impairment in patients with Alzheimer disease (AD). METHOD Fifty-three patients with AD were investigated. The evolution of cognitive decline over 12 months was evaluated by means of changes in Mini Mental State Examination (MMSE) and AD A...

Abstract Background and Aims Decreased bone mineral density (BMD) is well recognised in patients on dialysis. Lower DXA-BMD predicts incident fractures with CKD 3a-5D. However while age (BA) Xrays are routinely performed to assess delays density, DXA scans not available widely. We compared the utility of findings using automated measurements routine BA scans. Method In our tertiary paediatric r...

Once isolated, Listeria monocytogenes is easily grown on ordinary bacteriological media; however, initial isolation from clinical specimens may be unsuccessful unless the organism is present in large numbers, or the specimen is refrigerated in broth for several days to several months. In the absence of refrigeration, organisms were not recovered from some specimens showing histological evidence...

BACKGROUND Active and passive surveillance for avian influenza virus (AIV) and Newcastle disease virus (NDV) is widespread in commercial poultry worldwide, therefore optimization of sample collection and transport would be valuable to achieve the best sensitivity and specificity possible, and to develop the most accurate and efficient testing programs. A H7N2 low pathogenicity (LP) AIV strain w...

introduction: one of the main goals of endodontic treatment is to decrease the harboring bacteria within the root canal system and dentinal tubules. this experimental study attempted to investigate the antibacterial efficacy of three root canal irrigants in the presence and absence of smear layer (sl). methods and materials: a total of 210 sound extracted human single-rooted teeth were prepared...
