Expression of Digestive Enzymes and Nutrient Transporters in the Intestine of Eimeria-challenged Chickens
… reduction may be due to changes in expression of digestive enzymes and nutrient transporters in the intestine. The objective of this thesis was to examine the expression of digestive enzymes: APN and SI, peptide and amino acid transporters: Pept1, ASCT1, bo,+AT/rBAT, B0AT, CAT1/2, EAAT3, LAT1 and …

Gene Expression of Nutrient Transporters and Digestive Enzymes in the Yolk Sac Membrane and Small Intestine of the Developing Embryonic Chick
… posthatch. Nutrient uptake is mediated by digestive enzymes and membrane bound transporter proteins. The objective of this study was to determine expression profiles of nutrient transporters and digestive enzymes during incubation in the yolk sac membrane (YSM) and small intestine of …

Altered Morphology And Composition Of Zymogen Granules In Acute Pancreatitis
<p>In healthy physiology, pancreatic digestive enzymes secreted following a meal are stored as inactive zymogens within membrane bound secretory vesicles called Zymogen Granules (ZG), and activated extracellularly. In acute pancreatitis however, the digestive enzymes are prematurely activated …

Effects of Glucocorticoids and Limited Nursing on the Digestive Enzyme Ontogeny and Growth of Nursing Piglets (Maltase, Sucrase, Lactase, Amylase, Acth)
… hormone (ACTH) on the developing carbohydrate digestive enzymes and growth rate of nursing piglets. The response of these enzymes to increased creep feed consumption, produced by partial weaning, was also investigated. A total of 87 litters of piglets were used.

Evaluation of the antioxidant and anti-diabesity potential of cyclopia maculata using in vitro non-cell based screening models
… was assessed in terms of the inhibition of the digestive enzymes, α-glucosidase and pancreatic lipase

RBP-L and RBP-J Have Critical Roles in the Functioning of Two Forms of the Pancreas Transcription Factor Complex PTF1
… regulates the transcription of genes encoding digestive enzymes within the exocrine pancreas. The PTF1 complex forms on the rat elastase 1 (ELA1) promoter by synergistically binding to a 21 base-pair site comprising an E-box (CANNTG) and a TC-box separated by one helical turn. P48 binds the …

Activity of Analogs of Anticancer Drugs on the Serine Protease Enzymes Subtilisin and Chymotrypsin
… site. We are investigating the inhibition of the digestive enzymes chymotrypsin and subtilisin by analogs of the anticancer drug cisplatin and trying to discern trends in the inhibition as the active site residues vary. In our research, we found that the enzyme subtilisin did not show any …

An Evaluation of a Yeast-Derived Mannan Oligosaccharide and Its Mode of Action in Swine
… gastrointestinal tract due to the inability of digestive enzymes to hydrolyze Bio-Mos RTM. In a meta-analysis of 54 comparisons of nursery pigs fed Bio-Mos RTM versus no Bio-MosRTM, there was an overall 4.12% improvement in growth rate with a more pronounced response (4.60%; P < 0.05) to …

Chemical synthesis, cloning and expression of a gene encoding systemin, a proteinase inhibitor-inducing factor
… a feedback mechanism causing overproduction of digestive enzymes together with a decrease in appetite, leading to starvation. System in, a polypeptide proteinase inhibitor-inducing factor, when applied to cut stems of young tomato plants induces the accumulation of inhibitors in a manner similar …

Some bioactivity of triterpenes from stem bark of protorhus longifolia and their derivatives
… was evaluated on selected lipid and carbohydrate digestive enzymes. The effect of the compounds on glucose uptake in C2C12 muscle cells and 3T3-L1 adipocytes, and triglyceride accumulation in 3T3-L1 adipocytes was also investigated. The anticoagulant and anti-inflammatory activity was investigated …

Relation of crystalline style function to food availability and environmental conditions in South African mussels
… There is very little information on the digestive enzymes of South African mussels. The activity of these enzymes will be an important factor affecting the ability of the mussels to effectively utilise a food resource, and this may be a mechanism which partially accounts for their …

Identification and bioactivity evaluation of an amphibian skin Bowman-Birk-like trypsin inhibitor from Hylarana nigrovittata
… are a large family of conserved, proteolytic enzymes. They play a role in many bodily functions and some are digestive enzymes. Protease action can be controlled by protease inhibitors, therefore protease inhibitors also get involved in regulating numerical physiological problems and are …

Influence of feed efficiency ranking and maternal nutrition on gut microbiome, metabolome, and transcriptome in beef and dairy cattle
… ruminal bacteria and the activities of microbial digestive enzymes between M-eff and L-eff dairy cows during the peripartum period and early lactation. The results showed that M-eff cows enriched fibrolytic bacteria, propionate-producing bacteria, and lactate-removing bacteria whereas declined …

Acute Pancreatitis. Studies on smoking and protease activation.
… B is to play a role in the activation of digestive enzymes in acute pancreatitis, this probably occurs through activation of trypsinogen. The incidence of gallstone-related acute pancreatitis increased by 7.6% per year (95% confidence interval (CI), 4.0 to 11.4) in Malmö 1985?1999. The …

Relationships between invertebrate detritivores and gut bacteria in marine systems
Aspects of the feeding strategies and digestive invertebrate-microbial interactions of two saltmarsh thalassinid detritivores, the mudprawn Upogebia africana (Ortmann) and the sandprawn Callianassa kraussi Stebbing were examined. Resources available in their respective habitats were investigated …

Morphogenesis of the Bacillus Anthracis Spore
… of heat, ultra-violet and ionizing radiation, digestive enzymes, and antimicrobials, the bacterial spore is one of the most-resistant forms of life on earth. Although most spores are harmless, several species' spores cause serious diseases such as tetanus, anthrax, gas gangrene, botulism, and …

Reproductive Genomics in the Stick Insect Clitarchus hookeri
… during sensory evolution. The annotation of digestive enzymes from both the midgut transcriptome and genome assembly revealed nine cellulase GH9 gene duplicates, four of which were absent in the midgut transcriptome, indicating they might have evolved new roles rather than digesting plant …

The role of Dietary Interventions in Broiler Intestinal Health and Immunity
… tissue morphology, mucin barrier integrity, digestive enzyme capacity, apoptotic and necroptotic cell death levels and the expression of inflammatory cytokines. Supplementation of diet with each mannan-rich fraction (MRF) increased villus height and villus surface area. In addition, crypt …

Cellular Events During Coccidial Infection in Chickens
… reduction may be due to changes in expression of digestive enzymes and nutrient transporters in the intestine. This can also lead to diminished intracellular pools of nutrients and inhibit pathogen replication. In this dissertation, further analysis of cellular events was performed. Expression of …
