This in vitro study compared the shear bond strength (SBS) and adhesive remnant index (ARI) of two systems for bonding orthodontic brackets to enamel. The first system involved a self-etching primer (Beauty Ortho Bond, BO) containing surface pre-reacted glass filler. The second involved a primer applied with phosphoric acid etching (Transbond XT, TX). Ninety-six extracted human premolars were d...

To help assess the causes and frequency of acute respiratory illnesses (ARI) during the first 18 months of life in Chile, a cohort of 437 children born in good health between May 1991 and April 1992 was followed at an urban health clinic in northern Santiago. Information was obtained from medical checkups performed at the clinic, from emergency health care services, from private physicians, and...

BACKGROUND AND PURPOSE Dynamic methods of measuring cerebral autoregulation have become an accepted alternative to static evaluation. This article aims to describe a set of data collected from healthy volunteers by a dynamic method, the purpose being to qualify and quantify expected results for those who may be designing a study using this technique. METHODS Cerebral blood flow velocity (CBFV...

BACKGROUND Acute respiratory infections (ARI) are frequent in children and complications can occur in patients with chronic diseases. We evaluated the frequency and impact of ARI and influenza-like illness (ILI) episodes on disease activity, and the immunogenicity and safety of influenza vaccine in a cohort of juvenile idiopathic arthritis (JIA) patients. METHODS SURVEILLANCE OF RESPIRATORY V...

Steep action potential duration (APD) restitution slopes (>1) and spatial APD restitution heterogeneity provide the substrate for ventricular fibrillation in computational models and experimental studies. Their relationship to ventricular arrhythmia vulnerability in human cardiomyopathy has not been defined. Patients with cardiomyopathy [left ventricular (LV) ejection fraction <40%] and no hist...

AIMS The effects of adrenergic activity and beta-blockade were studied in a canine experimental model of type-3 long QT syndrome (LQT3) induced by application of anthopleurin-A. METHODS AND RESULTS Boluses of epinephrine at 0.5 and/or 1.0 microg/kg were administered before and after propranolol, 0.3 mg/kg, and the distribution of the ventricular repolarization and the development of polymorph...

INTRODUCTION Approximately 25 million people in the United States visit their primary care physician each year for acute respiratory infections (ARI). They are a common cause of unnecessary prescription of antibiotics; despite well-validated national treatment guidelines, around 73% of adults with ARI are prescribed antibiotics in the United States. Inappropriate use of antibiotics has profound...

Saha Türkçesi bünyesinde barındırdığı kelimeler ve yapılar açısından her zaman incelemelere konu olmuş, Türk dilinin tarihsel gelişimler hakkında bilgi vermiştir. Konuşurlarının yaşadığı coğrafyanın genel coğrafyasından uzak olması, süreçte çevresindeki etkileşimde bulunduğu farklı dillerden etkilenmiş olması nedeniyle Türkçesinde farklılaşmalar meydana gelmiştir.
