OBJECTIVE To investigate whether adolescents living in a high-walkable town centre are more physically active than those living in a less-walkable suburb. METHODS This cross-sectional study was conducted in Izegem (Belgium). Data collection took place in spring 2007. One high-walkable urban neighbourhood and one less-walkable suburban neighbourhood were selected, based on objective connectivi...

Background Although tests for occult blood in the feces are widely used to screen for colorectal cancers, there is no conclusive evidence that they reduce mortality from this cause. We evaluated a fecal occult-blood test in a randomized trial and documented its effectiveness. Methods We randomly assigned 46,551 participants 50 to 80 years of age to screening for colorectal cancer once a year, t...

BACKGROUND The study objectives were to examine whether: 1) sedentary time is associated with sleep duration, 2) sedentary time predicts the metabolic syndrome (MetS) independent of sleep duration and vice versa, and 3) sedentary time and sleep duration have an interactive effect on the MetS. METHODS This cross-sectional study is based on the 2003-2006 National Health and Nutrition Examinatio...

Adenoviruses have been recognized as important causal pathogens of community-acquired diarrhea (CAD) among children, but their role in hospital-acquired diarrhea (HAD) is not well-understood. Hospitalized children with acute diarrhea and children who visited the outpatient department due to diarrhea were investigated from 2011 to 2012. Adenovirus was detected in stool specimens by PCR and furth...

BOULANT, J. A., AND K. E. BIGNALL. Hypothalamic neuronal responses to peripheral and deep-body temperatures. Am. J. Physiol. 225(6) : 1371-1374. 1973.-Single-unit activity was recorded in the anterior hypothalamic-preoptic area of anesthetized rats and ground squirrels. The local thermosensitivity (i.e., impulses/set . “C) of 28 units was determined by their change in firing rate to changes in ...

The steady-state levels of calcyclin mRNA are regulated by growth factors. Using deletion mutants of the 5'-flanking region and a linked reporter (the bacterial chloroamphenicol transferase gene), we have investigated the elements of the calcyclin gene's promoter that respond to growth factors. By a transient expression assay after transfection in BALB/c/3T3 cells, we have been able to show tha...

Chinese white dolphins (Sousa chinensis) inhabiting shallow coastal waters are vulnerable to impacts from human activities in the near shore waters. This study examined the population of Chinese white dolphins occurring off the coast of Zhanjiang in the northern South China Sea. A total of 492 Chinese white dolphins were identified, 176 of which were photographed on more than one occasion. The ...
