The flexibility of digestive traits characterizes a standard model of physiological flexibility, demonstrating that animals adjust their digestive attributes in order to maximize overall energy return. Using an intraspecific experimental study, we evaluated the amount of flexibility in digestive tract mass and length in individuals from field mouse populations inhabiting semi-arid and temperate...

The purpose of this study was to examine visceral fat mass as well as other measures abdominal body composition in National Football League (NFL) players before the start of the season. Three hundred and seventy NFL football players were measured before the start of the season using dual-energy x-ray absorptiometry. Regional fat and lean mass was measured for each player. Players were categoriz...

background & aim: st john's wort (hypericum perforatum l.) contains hypericin and hyperforin as the main components of the extract that binds with gaba and sigma opioid receptors. this herb has many pharmacological effects, including analgesic, sedative, soothing, antispasmodic, anticonvulsant, anti-depressant, and anti-bacteria. in this study examined the effect of two concentrations of hy...

Dr. Dan Sadowski Co-Chair, CDDW 2012 ROLE OF THE GUT MICROBIOME IN HUMAN HEALTH AND DISEASE During the 2012 Canadian Digestive Diseases Week (CDDW) the role of the gut microbiome in human health and disease was discussed. The microbial community residing in the intestinal tract is a delicate balance of beneficial and potentially harmful microbial species (Figure 1). There is increasing recognit...

Digestive organ development occurs through a sequence of morphologically distinct stages, from overtly featureless endoderm, through organ primordia to, ultimately, adult form. The developmental controls that govern progression from one stage to the next are not well understood. To identify genes required for the formation of vertebrate digestive organs we performed a genetic screen in zebrafis...

abstract   background: hysterectomy is the second most common major surgery procedure done after cesarean section by gynecologists in many countries and the most common procedure is total abdominal hysterectomy (tah). the incidence of laparoscopically assisted vaginal hysterectomy (lavh) performed for benign lesions has progressively increased in recent years. our objective was to compare the r...

The ontogenetic development of the digestive tract and accessory organs in large yellow croaker (Pseudoscianea crocea) was described using light microscopy from hatching up to the juvenile stage (40 days post hatch, dph). At 3 dph (4.1 0.1 mm total length, LT), coinciding with the buccopharynx opening, larvae started to feed exogenously, and the digestive tract consisted of a welldeveloped bucc...

The status of anaerobic zoosporic (Chytridiomycota) fungi along the entire digestive tract of sheep was assessed both analytically and microscopically. Digest samples were taken from different segments of the digestive tracts of three newly killed sheep that previously had been used in experimental dietary studies. These digest samples were tested for the presence of rumen fungi by assessing th...

An experiment was carried out to determine the effect of corn silage particle size and fat supplements on performance, solid passage rate through the digestive tract, and chewing behavior in dairy cows. The forages were coarse or fine corn silage with geometric means of 8.8±2.7 and 5.6±2.8 mm, and alfalfa with geometrics means of 7.0±3.3 mm, and fat supplements were neutral fat (palm) and soy-o...
