BACKGROUND The purpose of this study was to explore the socio-ecological determinants of participation and dropout in organised sports in a nationally-representative sample of Australian children. METHODS Data were drawn from Waves 3 and 4 of the Longitudinal Study of Australian Children. In total, 4042 children aged 8.25 (SD = 0.44) years at baseline were included, with 24-months between Wav...

Complete resection case total tubular duplication that requires or subtotal colectomy undesirable children.Case Presentation: This presented simple surgical technique for treating complete colonic without resection. A 2 months old female baby with abdominal distention and stool complaint c...

CONTEXT Irritable bowel syndrome (IBS) is a functional bowel disease characterized by abdominal pain and altered intestinal habits. The pathophysiology of IBS remains unclear. Recent studies have demonstrated that some IBS patients, especially in diarrhea-predominant IBS (IBS-D), display persistent signs of minor mucosal inflammation and a modified intestinal microflora. The mesalazine has know...

Editor’s Note: Every departing Medical Student, Graduate Student, Urology Research Resident, and Post-Doctoral Fellow trained in Dr. Donald S. Coffey’s laboratory or classroom for 4 decades has been given this “real final exam”—in either oral, written, or both forms. Some believe the wisdom in it passed on to the next generations of cancer researchers is as vast and generous and dedicated to th...

In this paper, I review the contour grouping approaches towards segmentation of images. Classifying the existing literature into local and global methods, I show how the grouping methods have improved over time, moving from local to global and from heuristic to probabilistic. Requirements for performance evaluation of grouping algorithms are also discussed.

ly one can define a Lie group as a smooth manifold which is also a group such that inversion and multiplication are smooth maps. A special case we focus on is any (topologically) closed subgroup of any SL(`,R). The major examples of “classical” Lie groups are SL(n,R), SO(m,n) (with g Im,ng = Im,n), SU(m,n) (same as SO but with conjugate transpose and complex elements), and Sp(2m,R) (similar to ...

Randomized cross-over studies were undertaken to determine the effects of daily dietary supplements of pectin (12 g/d), cellulose (15 g/d) and lignin (12 g/d) on stool characteristics of healthy volunteers. Detailed dietary records were kept throughout the study. Stool collections over 48 h were used to determine mean stool pH and weight. The single stool transit time was measured using radio-o...

BACKGROUND Diarrhea is a leading cause of childhood morbidity and mortality in sub-Saharan Africa. Data on risk factors for mortality are limited. We conducted hospital-based surveillance to characterize the etiology of diarrhea and identify risk factors for death among children hospitalized with diarrhea in rural western Kenya. METHODS AND FINDINGS We enrolled all children <5 years old, hosp...
