Fecal immunochemical testing (FIT) is superior to guiac-based testing if we are looking for blood in stools, as it has better one-time colorectal cancer sensitivity and specificity and better patient acceptance. In this issue of the journal, Cai and colleagues (beginning on page 1572) and Khalid-de Bakker and colleagues (beginning on page 1563) present new information about the one-time test pe...

background and aims. cad/cam systems facilitate the use of zirconia substructure materials for all-ceramic copings. this in vitro study investigated the marginal and internal fit of zirconia copings made with cad/cam system and slip-casting method. materials and methods. sixteen cad/cam made zirconia copings and 16 slip-cast made zirconia copings were fabricated and cemented with glass-ionomer ...

I N B R I E F We are used to thinking of intelligence as largely a matter of genetic inheritance, but that is not the whole picture. What we do aff ects our mental wellbeing: staying physically and mentally active helps us stay sharp as we age. Nevertheless, our personal eff orts to bolster cognitive enhancement cannot forestall all declines in our cognitive performance. What is especially surp...

BACKGROUND Although youth are exposed to many forms of violence, most studies have been concentrated on only one type of violence exposure and focused on older adolescents or very young children. Little is known about direct and indirect effects of violent stressors on the health of African American adolescents in urban middle schools or the cumulative effect of multiple forms of exposures. O...

Background: Norovirus is a common cause of outbreaks of acute gastroenteritis in health- and child-care settings, with serial outbreaks also frequently observed aboard cruise ships. The relative contributions of environmental and direct person-to-person transmission of norovirus has hitherto not been quantified. Objective: We employ a novel mathematical model of norovirus transmission, and fit ...

Understanding the regulation of key genes involved in plant iron acquisition is of crucial importance for breeding of micronutrient-enriched crops. The basic helix-loop-helix protein FER-LIKE FE DEFICIENCY-INDUCED TRANSCRIPTION FACTOR (FIT), a central regulator of Fe acquisition in roots, is regulated by environmental cues and internal requirements for iron at the transcriptional and posttransc...

A model was developed specifying that the number of hours employees spend providing care to or interacting with elderly parents predicts conflict between the roles of employee and caregiver. Interrole conflict was subsequently expected to predict partial absence from work (e.g., arriving late). Seventeen employed eldercare providers completed a daily questionnaire for 20 work days. The data wer...

Purpose: Present research was conducted with aim of investigating the fit pattern of family function and relationship beliefs mediated by differentiation of self with social interest. Methodology: This study was cross-sectional in terms of purpose was applied and in terms of implementation method was quantitative from type of correlation. The study population was students of Islamic Azad Unive...

Aim: The objective of this work was to study the effects of formulation variables on the release kinetics of paracetamol tablet formulation. Materials and Methods: Paracetamol tablets were formulated using wet granulation (WG) and direct compression (DC) using two predetermined pressures. Avicel, dicalcium phosphate (DCP) and pregelatinized starch (PGS) were used as directly compressible...

Background and Objectives: There are several predictor variables for speech anxiety (SA) among students. Affective balance (AB) and social intelligence (SI) are two main factors in this field. In this study, we assess the mediating role of consequence expectation (CE) among these variables. Accordingly, this study aims to explore a model of the relationships between AB, SI, and SA mediated by C...
