Students' attitudes toward caries prevention can impact their receptivity to training and subsequent involvement in preventive services in their future practices. The aim of this study was to evaluate dental students' opinions and knowledge regarding caries management and prevention at the University of Florida College of Dentistry. A twenty-six-item written survey instrument was administered t...

BACKGROUND Recent clinical trials have demonstrated that aggressive lipid lowering by statins could prevent recurrent events after acute coronary syndrome (ACS). We hypothesized that this efficacy was caused by a significant reduction in plaque volume by aggressive LDL cholesterol (LCL-C) lowering. The present study investigated the effect of early statin treatment on plaque volume of a nonculp...

HYPOTHESIS Direct inguinal hernia repair with acellular human dermis (AHD) may offer greater symptom improvement and lower risk of hernia recurrence than anatomical repair without mesh (AWM) after mesh removal (with or without neurectomy) for postherniorrhaphy inguinodynia. DESIGN Retrospective cohort study with long-term follow-up. SETTING Tertiary referral center for mesh inguinodynia. ...

in this study artificial neural network (ann) was used for modeling of wastewater treatment plants with using. for this purpose, the base of the quality parameters measured at the plant input, plant output value was predicted. neural network input data, including temperature (t), biochemical oxygen demand (bod), chemical oxygen demand (cod), total suspended solids (tss), total solids (ts) and p...

Doppler echocardiography was used to study the function of bioprosthetic heart valves by noninvasive means in 32 patients aged 29 to 72 years at various postoperative intervals. There were 24 Ionescu-Shiley, four Hancock, and four Carpentier-Edwards prostheses, 19 in the aortic and 13 in the mitral position. Initial studies were performed at a mean of 2.3 years after implantation and were repea...

BACKGROUND: Some studies have described the pattern of limb fractures and dislocation in Nigeria. However, with recent increase in vehicle and motorbike transport, we aimed to describe the pattern to note any differences from previous reports. METHODS: This was a retrospective study of all patients with accidental fractures and dislocations treated at the Federal Medical Centre Owerri between J...

Brain development during childhood and adolescence differs between boys and girls. Structural changes continue during adulthood and old age, particularly in terms of brain volume reductions that accelerate beyond age 35 years. We investigated whether brain structural change in mid-life differs between men and women. 43 men and 28 women from the Northern Finland 1966 Birth Cohort underwent MRI b...

Two hundred consecutive patients with malignant pleural effusion were reviewed. The pathologic etiology of malignant pleurisy was: primary lung cancer in 123 cases; five, mesothelioma; and 72 cases secondary to metastatic tumors. Adenocarcinoma of the lung and mammary cancer were the most frequent tumors causing malignant pleural effusion. The modalities employed in local treatment consisted of...
