Transmissible gastroenteritis virus (TGEV) is a coronavirus that causes villus atrophy, followed by crypt hyperplasia, reduces the activities of intestinal digestive enzymes, and disrupts the absorption of intestinal nutrients. In vivo, TGEV primarily targets and infects intestinal epithelial cells, which play an important role in glucose absorption via the apical and basolateral transporters N...

Increasing the tissue biomass and/or volume of the gastrointestinal tract (GIT) is commonly seen when animals feed on poor-quality diets. This increase can simply permit larger meal sizes, but may also rebalance nutritionally imbalanced ingesta by allowing selective absorption of limiting nutrients. In an insect herbivore, the migratory locust, a synthetic diet with a high ratio of protein to c...

Physiological digestion and absorption of nutrients within the gastrointestinal tract requires a complex interaction between motor, secretory, digestive, and absorptive functions that is vulnerable to a multitude of potential disturbances which may lead to global or specific malabsorption syndromes. Potential pathomechanisms that are illustrated in this article include insufficient mechanical b...

Previous in vitro studies showed that the small intestine has reserve capacities for absorption of nutrients. However, the size of the reserve capacity is controversial. Therefore, we measured the intestinal capacity for absorption of energy in relation to the postprandial gastric delivery of energy into the gut. In minipigs, a 150-cm length of jejunum was perfused (1-8 kcal/min) with four nutr...

in order to study the effect of uniconazole and cycocle growth regulators on growth, yield and nutrients content of pearl millet in drought stress condition, a field experiment was conducted in 2007-2008 in agriculture research center of zabol university. the experiment was conducted in split plot base on randomized completely block design with tree replications. main plots were different level...

plant growth promoting rhizobacteria and arbuscular mycorrhizal fungi can inhanced plant growth by increasing nutrient uptake. in order to investigate the effect of pgpr and amf on some morphological parameters, macro (nitrogen, phosphorus, potassium, calcium and magnesium) and micro (iron, zinc and copper) nutrients uptake, percentage of root colonization and some morphological factors of pepp...

The present study determined and compared contents of macro- (Nitrogen-N, Phosphorus-P, Potassium-K, Calcium-Ca, Magnesium-Mg) and micro- (Zinc-Zn, Iron-Fe, Manganese-Mn, Cupper-Cu) nutrients in four seagrass species big-leaved (BL) Halophila ovalis (R. Br.) Hook. f., small-leaved (SL) H. ovalis (R. Br.) Ascherson, H. spinulosa (R. Br.) Aschers. in Neumayer and Halodule uninervis (Forssk.) Asch...

The human colon is a dynamic organ, involved in a vast array of functions, including the absorption of water and electrolytes, the salvage of unabsorbed nutrients, and the transport of luminal contents as feces. While not an organ essential for life, the colon still plays a major role in maintaining the overall health of the human body. Understanding these physiologic principles is integral to ...

The results of studies on gnotobiotic and conventional animals indicate that intestinal bacteria interfere with absorption of nutrients. The microflora could exert this undesirable activity by a direct action on the gut wall or the gut function, as well as by transformation of a variety of exogenous and endogenous substances into unabsorbable or potentially toxic compounds. This short review pr...
