This paper presents a statistical method for determining pathogen sources and for evaluating the effectiveness of conventional Best Management Practices (BMPs) in reducing fecal coliform bacterial impairment using water quality data monitored from 1980 – 2006 in the Mermentau River Basin. The statistical method mainly involves (1) determination of seasonal variations in the mean of flow and fec...

OBJECTIVE Functional constipation and fecal incontinence are common childhood gastrointestinal conditions. Both conditions may be associated with behavioral problems. Attention-deficit/hyperactivity disorder (ADHD) is the most common behavioral disorder of childhood, characterized by shortened attention span and hyperactivity. We hypothesize that a diagnosis of ADHD increases the risk for funct...

Large-scale cohort studies are currently being designed to investigate the human microbiome in health and disease. Adequate sampling strategies are required to limit bias due to shifts in microbial communities during sampling and storage. Therefore, we examined the impact of different sampling and storage conditions on the stability of fecal microbial communities in healthy and diseased subject...

The present study examined the feasibility of measuring the steroid hormone corticosterone in fecal extracts of epaulette sharks, Hemiscyllium ocellatum. Six immature, captive-raised epaulette sharks (four females and two males) were obtained from two different zoos and were maintained in a closed-system, 530-liter aquarium. After a one-month adaptation, fecal samples were collected daily from ...

Brooks River in Katmai National Park is one o f the most famous bear-viewing areas in the world. The close proximity of brown bears and humans at Brooks River poses a question vital to the management of these bears: do ongoing human activities at Brooks River induce stress in brown bears that rely on this fishing area for much of their nutritional intake? Fecal monitoring of glucocorticoids is ...

The measurement of fecal tumor M2-pyruvate kinase (PKM2), overexpressed in tumor cells, has been proposed as a novel tool for detecting colorectal cancer (CRC). However, the sensitivity and specificity of this test varied among studies. The aim of this meta-analysis was to determine the diagnostic accuracy of fecal PKM2 for CRC and to evaluate its utility in the CRC screening. It was compared t...

Splenda is comprised of the high-potency artificial sweetener sucralose (1.1%) and the fillers maltodextrin and glucose. Splenda was administered by oral gavage at 100, 300, 500, or 1000 mg/kg to male Sprague-Dawley rats for 12-wk, during which fecal samples were collected weekly for bacterial analysis and measurement of fecal pH. After 12-wk, half of the animals from each treatment group were ...

Svalbard reindeer (Rangifer tarandus platyrhynchus) is a non-migratory subspecies of reindeer inhabiting the high-arctic archipelago of Svalbard. In contrast to other Rangifer tarandus subspecies, Svalbard reindeer graze exclusively on natural sources of food and have no chance of ingestion of any crops. We report the use of a non-invasive method for analysis of fecal microbiome by means of seq...

SCOPE This work aims to evaluate changes in the fecal metabolomic profile due to grape seed extract (GSE) intake by untargeted and targeted analysis using high resolution mass spectrometry in conjunction with multivariate statistics. METHODS AND RESULTS An intervention study with six crossbred female pigs was performed. The pigs followed a standard diet for 3 days, then they were fed with a s...

background: microsporidia species are obligatory intracellular agents that can in­fect all major animal groups including mammals, birds, fishes and insects. whereas world­wide human infection reports are increasing, the cognition of sources of infec­tion particularly zoonotic transmission could be helpful. we aimed to detect zoono­tic microsporidia spore in fecal samples from some animals with ...
