corophium volutator (pallas) has been recommended by the paris commission as one of the standard species for testing chemical used in offshore oil and gas exploration/production. in the present study, gut contents of corophium volutator have been analysed by electron probe microanalysis (epma) for baso4 and other heavy metal impurities after exposure tto spiked sediments following a standard as...

Prouroguanylin is a gastrointestinal paracrine signal and prohormone that is secreted after nutrient ingestion. In this issue of the JCI, Valentino et al. show that prouroguanylin is converted to uroguanylin in the CNS, which can activate guanylyl cyclase 2C (GUCY2C) receptors in the brain to reduce food intake in mice. This 16-amino acid residue peptide is a novel component of the gut-brain ax...

Potato residue is a rich source of dietary fibre. Herein, the effects unmodified and enzymes (cellulase xylanase) modified potato fibres on distribution intestinal microbiotas production short-chain fatty acids (SCFAs) C57BL/6 mice were evaluated. Results showed that enzymatic modification increased soluble fibre content in residue. Administration these promoted acetic acid, n-butyric iso-butyr...

Mixing the residue in the gut has been studied in 24 normal subjects using five different types of radio-opaque pellets. By giving single doses of different pellets to the subjects on three successive days and measuring their appearances in the stool by radiographs evidence of mixing was found in 83% of studies. Mean transit time (MTT) of markers through the gut was measured from the single dos...

The gastrodermis of Atriaster heterodus Lebedev & Paruchin, 1969 (Polyopisthocotylea), a gill parasite from Diplodus argenteus (Valenciennes, 1930), is composed of "U"-shape hematin cells and a connecting syncytium, both having cytoplasmic lamellae. These cells show outgrowths and bent folds which were sent to enclose lumen material. The trapped material was then subjected to endocytosis. The n...

We find that the minimum distance of the binary [137; 69] quadratic residue code is 21.
