INTRODUCTION The purpose of this laboratory study was to evaluate the effect of acidic pH on the sealing ability of calcium-enriched mixture (CEM) cement and mineral trioxide aggregate (MTA) apical plugs. METHODS AND MATERIALS Seventy single-rooted human maxillary anterior teeth were recruited. The teeth were randomly divided into 4 experimental groups (n=15), and 1 negative and 1 positive co...

BACKGROUND Debonding is one of the frequent causes of failure experienced in fiber-reinforced composite posts, and establish along post space-dentin adhesive interface. The purpose of this study was to assess push-out bond strength of a fiber-reinforced post system using four different resin cements. MATERIALS AND METHODS In this in-vitro study 40 mandibular premolars were decoronated, and ro...

BACKGROUND We aimed to investigate risky sexual behaviors (RSBs) and condom use barriers in Iranian men with substance use disorders (SUDs). METHODS Of the total 1800 outpatient drug free (ODF) and methadone maintenance treatment program (MMTP) active centers in Tehran, Iran, six were selected to participate in the current study. Data were collected (n = 300 men) using three questionnaires in...

BACKGROUND Type D personality is based on two global and stable personality traits, including negative affectivity (NA) and social inhibition (SI). The aim of this study was to examine the relationship between type D personality and perceived social support in post myocardial infarction (MI) patients. METHODS One hundred seventy six consecutive patients following MI admitted to the cardiac ca...

Rationale Radium-223-Dichloride (Ra-223) is an alpha-emitter, used to treat bone metastases. Patients with high metastatic burden and/or with increased trabecular bone uptake could present a higher incidence of hematologic toxicity. We hypothesized that these two factors are predictors of bone marrow failure. Material and Methods A computer algorithm discriminated between trabecular bone (BVo...

Because of its importance in directing evolutionary trajectories, there has been considerable interest in comparing variation among genetic variance-covariance (G) matrices. Numerous statistical approaches have been suggested but no general analysis of the relationship among these methods has previously been published. In this study, we used data from a half-sib experiment and simulations to ex...

The misclassification error which is usually used in tests to compare classification algorithms, does not make a distinction between the sources of error, namely, false positives and false negatives. Instead of summing these in a single number, we propose to collect multivariate statistics and use multivariate tests on them. Information retrieval uses the measures of precision and recall, and s...

The current study aimed to investigate temporal processing in Chinese children with Attention-Deficit-Hyperactivity Disorder(ADHD) using time production, time reproduction paradigm and duration discrimination tasks. A battery of tests specifically designed to measure temporal processing was administered to 94 children with ADHD and 100 demographically matched healthy children. A multivariate an...

Methods 30 males (22.5 yrs; 81.1 kg) ingested either leucine (60 mg/kg/bw), BCAA (120 mg/kg/bw), or placebo. Supplementation was ingested at 3 time points (1/3 of the total dosage at each time point): 30 minutes prior to RE, and immediately preand post-RE. The subjects performed 4 sets of leg press and leg extension at 80% 1 RM to failure. Rest periods between sets and exercises were approx. 15...

Bu çalışmanın amacı, egzersiz katılımcıları için bağımlılığı ve sosyal görünüş kaygısındaki farklılıkları belirlemek semptomları ile kaygısı arasındaki ilişkiyi tespit etmektir. Araştırma grubunu 79 kadın 167 erkek olmak üzere toplam 246 (ortalama yaş: 26,94 yıl) katılımcısı oluşturmuştur. Katılımcıların tümü “Egzersiz Bağımlılığı Ölçeği-21” “Sosyal Görünüş Kaygısı Ölçeği”ni cevaplamışlardır. P...
