Ingestion of artificial debris is considered as a significant stress for wildlife including sea turtles. To investigate how turtles react to artificial debris under natural conditions, we deployed animal-borne video cameras on loggerhead and green turtles in addition to feces and gut contents analyses from 2007 to 2015. Frequency of occurrences of artificial debris in feces and gut contents col...

BACKGROUND Research in vulnerable individuals must insure voluntariness and minimize negative reactions caused by participation. This study aimed to describe consent and completion rate in young psychiatric patients in relation to study components, degree of disability and to compare response to research participation in patients and controls. METHODS Between 2012 and 2015, 463 patients with ...

Using a method for nitrosamine analysis that gives high recovery values and that is free from artifactual synthesis of nitrosamines, we have shown that human feces do not contain volatile nitrosamines (detection limit, 0.1 to 0.5 /ng/kg). We also showed that nitrosation reactions are not catalyzed by fecal organisms. Following a 2-day anaerobic incubation of feces with either a secondary aminé...

Calprotectin is a marker of inflammation and zonulin is a marker of intestinal permeability. Diets with lower carbohydrate content and higher contents of fat, fiber and protein, e.g., Okinawan-based diet, are considered to reduce inflammation and intestinal permeability. The aim of the present study was to evaluate calprotectin and zonulin levels in serum and feces after intervention with an Ok...

Changes in body odor are known to be a consequence of many diseases. Much of the published work on disease-related and body odor changes has involved parasites and certain cancers. Much less studied have been viral diseases, possibly due to an absence of good animal model systems. Here we studied possible alteration of fecal odors in animals infected with avian influenza viruses (AIV). In a beh...

The metabolism and excretion of [(14)C]sitagliptin, an orally active, potent and selective dipeptidyl peptidase 4 inhibitor, were investigated in humans after a single oral dose of 83 mg/193 muCi. Urine, feces, and plasma were collected at regular intervals for up to 7 days. The primary route of excretion of radioactivity was via the kidneys, with a mean value of 87% of the administered dose re...

Eimeria species are frequently found in water buffalo (Bubalus bubalis) in Brazil. Here, we report those Eimeria spp. that infect buffalos during their first year of life. Fresh fecal samples were examined from 2 groups (1 group/yr for 2 yr, 2000-2002), each with 18 water buffalo calves (both sexes), from birth through 12 mo of age, in Selvíria, MS, Brazil. Five oocyst morphotypes were observed...

The aim of this study was to establish radioimmunoassay (RIA) for fecal estrone sulfate (E1S) and to elucidate changes in fecal E1S during pregnancy in the sow. Fecal E1S was extracted on a commercially available solid phase column, and the E1S fraction obtained was subjected to RIA. The sensitivity of the RIA was 8.5 pg/tube. The intra- and inter-assay coefficients of variation were 8.8-8.9% a...

Cats are important in the epidemiology of Toxoplasma gondii because they are the only hosts that excrete environmentally resistant oocysts in feces. In the present study, hearts, serum, and feces from 36 feral cats from Addis Ababa area, Ethiopia, were examined for T. gondii infection. Antibodies to T. gondii were determined with the modified agglutination test (MAT, cutoff 1:25); 33 cats were ...

When studying digestibility, the respective parts of the exogenous, endogenous and bacterial fractions in the digesta or feces must be measured. The proportions of proteins from different sources may be estimated by comparing their amino acid composition with those of reference sources. This study describes the composition of endogenous and microbial proteins, i.e. meconium of piglet small inte...
