The ontogenesis and specific activities of pancreatic (trypsin, chymotrypsin, amylase and lipase) and intestinal enzymes (alkaline phosphatase, aminopeptidase N) were investigated in Kutum (Rutilus frisii Kutum) from the onset of exogenous feeding (3 day after hatching, DAH) to the juvenile stage at 50 DAH. Trypsin- and chymotrypsin-specific activity showed similar patterns and increased with l...

The main triglyceride-lipase (TG-lipase) from the fat body of Manduca sexta has been identified as the homolog of Drosophila melanogaster CG8552. This protein is conserved among insects and also shares significant sequence similarity with vertebrate phospholipases (PLs) from the phosphatidic acid preferring-phospholipase A1 (PA-PLA(1)) family. It is shown here that the TG-lipase is also a PL. T...

In the present study was performed to evaluate the follicular growth and hormonal changes after ovarian artery ligation in rats. Fifty six virgin 90-day–old female rats were used. The rats were chosen from 100 female rats by a vaginal smear, which showed that they were synchronized in estrous phase of the menstrual cycle. Animals were kept in seven cages (n=8 in each) at a temperature of 22 ± 2...

background: a precise understanding of the mechanism of human neointimal stenoses and atherosclerotic fibrous plaques , which give rise to thromboses in vital arteries, requires a suitable animal model that would mimic the same characteristics well. we developed a rabbit model of neointimal stenosis and fibrotic plaque rupture in the carotid artery to visualize the lesion progress and to charac...

AIM The evaluation of the uterine artery recanalization rate and color Doppler parameters during follow-up after bilateral uterine artery ligation (BUAL) for postpartum hemorrhage (PPH) related to uterine atony. MATERIAL AND METHOD A total of 40 female patients who underwent BUAL for PPH related to uterine atony and 96 females who gave birth without complication at Hatay Obstetrics and Gyneco...

The presence of NaCl-resistant, neutral triacylglycerol hydrolase (lipase) activity in rat adrenal gland, ovary and testis was studied. Both adrenals and ovaries but not testes were found to contain such a lipase. The activity of the enzyme in the adrenal gland was lowered during cortisol treatment and hypothyroidism. An elevated adrenal lipase activity was found during hyperthyroidism. Pseudo-...

T mobilization of fatty acid from triglycerides and cholesterol esters provides the primary source of energy in mammals. Hormone-sensitive lipase (HSL) is a multifunctional tissue lipase that plays a critical role in this process. The enzyme has broad specificity, catalyzing the hydrolysis of tri-, di-, and monoacylglycerols, as well as cholesterol esters. HSL has been studied most extensively ...

During late gestation, although maternal adipose tissue lipolytic activity becomes enhanced, lipolytic products cross the placenta with difficulty. Under fasting conditions, free fatty acids (FFA) are used for ketogenesis by the mother, and ketone bodies are used as fuels and lipogenic substrates by the fetus. Maternal glycerol is preferentially used for glucose synthesis, saving other gluconeo...
