Context. Since about half of all main-sequence stars reside in multiple star systems, it is important to consider the effect binarity on evolution planetesimal belts these complex systems. Aims. We aim see whether debris evolving between two may be impacted by presence companion and this leaves any detectable signature that could observed with current or future instruments. Methods. a circumpri...

Cystoscopy and cytology are the standard modalities used to diagnose and early detect persistent or recurrent bladder cancer. One of the possibilities of improvement in the diagnosis of bladder cancer was the introduction of assessment of tumor markers, especially evaluated in urine. The results of the recent studies on CYFRA 21-1, soluble cytokeratin 19 fragments, indicated that it is one of t...

BACKGROUND/AIM Nosocomial bloodstream infections (BSI) contribute to grater morbidity and mortality rates, as well as to increasing length of hospital stay and health care costs. All patients with nosocomial BSI identified during the one-year period were studed to identify microbiological factors associated with these infections. METHODS A one-year prospective cohort study was performed in pa...

Introduction: Developmental changes in atrioventricular nodal conduction time and refractoriness have been shown in several studies. Prevalence of atrioventricular nodal reentrant tachycardia (AVNRT) is clearly age-dependent. The purpose of this study was to determine developmental changes of basic and frequency-dependent electrophysiological properties of the atrioventricular node (AV-node)...

The present study sought to explore the relationship between Iranian EFL teachers' brain dominance, teaching experience and their teaching style. The study population consisted of all EFL teachers of high schools in Shiraz holding a B.A degree, with the sample consisting of 100 participants recruited through convenience sampling. The study employed a descriptive correlational design. To collect...

Abstract Background The Russian tobacco control law (TCL), implemented nationwide, aims to reduce smoking-related morbidity and mortality. However, its effects may vary among regions. We aimed assess the of TCL on rates hospital admissions (HA) for angina pectoris (AP) myocardial infarction (MI) in Federation (RF) 10 regions relation enforcement TCL. Methods analysed HA AP MI compare periods be...

The aim of this study was to evaluate clinical and microbiological effects of subgingival minocycline microgranules when used as an adjunct to scaling and root planing in subjects with Chronic periodontitis. Twenty-six non-smoker volunteers participated in the study. Four opposite sites, clinically standardized, with bleeding on probing (BOP) and pocket depth (PD) ≥ 6 mm were selected. Baseline...

BACKGROUND CD56 expression has been associated with a poor prognosis in lymphoid neoplasms, including T-cell acute lymphoblastic leukemia (T-ALL). MicroRNAs (miRNAs) play an important role in lymphoid differentiation, and aberrant miRNA expression has been associated with treatment outcome in lymphoid malignancies. Here, we evaluated miRNA expression profiles in normal thymocytes, mature T-cell...

Calcium lactate crystals that sometimes form on Cheddar cheese surfaces are a significant expense to manufacturers. Researchers have identified several postmanufacture conditions such as storage temperature and packaging tightness that contribute to crystal formation. Anecdotal reports suggest that physical characteristics at the cheese surface, such as roughness, cracks, and irregularities, ma...

BACKGROUND Metal-on-metal prostheses undergo wear and corrosion, releasing soluble ions and wear particles into the surrounding environment. Reports described early failures of the metal-on-metal prostheses, with histologic features similar to a Type IV immune response. Mechanisms by which metal wear products and metal ion causing this reaction are not completely understood, and the effects of ...
