We examined the pH and Eh of the digestive tract of 23 species of mixed-grass prairie grasshoppers, and asked whether these traits were associated with the species breadth and forb composition of their diets. We report that the gut lumen of all grasshoppers was oxidizing and ranged from slightly acid to neutral depending on the gut region and species. Although gut physicochemical conditions dif...

OBJECTIVE To develop mixed models for examining longitudinal associations between rates of change in visceral, subcutaneous abdominal, and total body fat with rates of change in fasting insulin (FI) and insulin sensitivity (SI) over 3 years in children. RESEARCH METHODS AND PROCEDURES Seventy-seven children (mean age, 8.3 years at baseline) from Birmingham, Alabama, with three or more annual ...

  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...

Oral delivery is the most common and preferred route of drug administration although the digestive tract exhibits several obstacles to drug delivery including motility and intraluminal pH profiles. The gut milieu represents the largest mucosal surface exposed to microorganisms with 10(10-12) colony forming bacteria/g of colonic content. Approximately, one third of fecal dry matter is made of ba...

BACKGROUND The influence of physical activity (PA) changes on risk of abdominal fat gain in midlife women has not been studied using objective measures and controlling for potentially confounding variables. METHODS Changes in PA were assessed within a prospective cohort of 233 middle-age (40 +/- 3 years), nonobese, nonsmoking, primarily Caucasian women by using accelerometers, worn continuous...

Amyloidosis is a heterogeneous group of diseases in which the extracellular deposition abnormal fibrillar proteins disrupts tissue structure and function. Intestinal involvement very rare manifestation amyloidosis compared to most affected organs, heart kidneys. Damage gastrointestinal tract may be only amyloidosis, or - more often component several organs systemic amyloidosis. Any part digesti...

The influence of excess total and abdominal adiposity on cardiovagal baroreflex gain remains unclear. We tested the hypotheses that cardiovagal baroreflex gain would be reduced in men with 1) higher [higher fat (HF), mass >20 kg, n = 11] compared with lower [lower fat (LF), mass <20 kg, n = 10] levels of total body and abdominal fat and 2) higher abdominal visceral fat (HAVF; n = 10) compared w...

Interpopulation variation in the diet of the wood mouse, Apodemus sylvaticus, is well documented. In this study, we examined the gut morphology and apparent absorption efficiencies of two populations of wood mice whose diet in the field was known to differ. One population inhabited sand dunes, where food availability was relatively low and the diet was dominated by invertebrates. The other popu...
