This study was aimed to gain knowledge on the ontogeny of digestive enzymes in common carp larvae at the governmental Warm water Fish Aquaculture Center of Shahid Rajaee in Sari, Mazandaran, Iran. The ontogenetic development of pancreatic (trypsin, chymotrypsin, lipase and α-amylase) and intestinal (alkaline phosphatase and aminopeptidase-N) enzymes were assessed in common carp larvae from firs...

Flavonoid-rich extract prepared from Glycyrrhiza glabra has been found to be beneficial in patients with functional dyspepsia and was reported to possess some gut health-promoting properties such as antioxidant, anti-inflammatory and anti-Helicobacter pylori activities. In the present study, the flavonoid-rich extract of Glycyrrhiza glabra was evaluated for its compatibility with probiotic stra...

During the first two postnatal weeks the amount of RNA of the pancreatic cells evaluated biochemically is about 3 times lower than that of the cells in the adult rat. Accordingly, in the acinar cells the amount of rough membranes of endoplasmic reticulum and the fraction of the cell volume occupied by the RNAase removable basophilic substance are visibly lower than those of the adult. Radioauto...

OBJECTIVE To measure activities of digestive enzymes during postnatal development in dogs. SAMPLE POPULATION Gastrointestinal tract tissues obtained from 110 Beagles ranging from neonatal to adult dogs. PROCEDURE Pepsin and lipase activities were measured in gastric contents, and amylase, lipase, trypsin, and chymotrypsin activities were measured in small intestinal contents and pancreatic ...

MR 2 variety mulberry leaves were sterilized with UV light for 5, 10 and 15 minutes. These leaves were fed to PM x NB 4 D 2 hybrid silkworm Bombyx mori Linn. life stages and recorded the macromolecular contents (total protein, reducing sugar and glycogen) and digestive enzymes (amylase, invertase and protease) activities. Results revealed feeding of silkworm B. mori with UV treated mulberry lea...

In culture operations, the efficiency of a feed in promoting maximum growth in animal depends not only on its nutritive profile, but also on the animal’s inherent ability to consume, digest, absorb and metabolize the nutrients from the feed. Nutrient utilization in aquatic animals depends on the activity of their digestive enzymes [1,2]. Digestive processes in fish are less known than in animal...

The sand fly Lutzomyia longipalpis is the most important vector of American Visceral Leishmaniasis. Adults are phytophagous (males and females) or blood feeders (females only), and larvae feed on solid detritus. Digestion in sand fly larvae has scarcely been studied, but some glycosidase activities putatively involved in microorganism digestion were already described. Nevertheless, the molecula...

Insects that use ephemeral resources must rapidly digest nutrients and simultaneously protect them from competitors. Here we use burying beetles (Nicrophorus vespilloides), which feed their offspring on vertebrate carrion, to investigate the digestive and defensive basis of carrion utilization. We characterize gene expression and microbiota composition in the gut, anal secretions, and on carcas...

In this investigation, vacuoles containing tubular myelin proved to be digestive compartments with cytochemical reactivity for acid phosphatase and arylsulfatase. These cytochemical markers identify the secondary lysosomes, known to contain enzymes capable of hydrolyzing phospholipids like surfactant. Therefore, it appears that alveolar macrophages possess the enzymatic machinery for the degrad...
