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...

-Plant roots and soil organisms increase phosphorus availability by releasing acid and alkaline phosphatase. Organic phosphorus compounds are hydrolysed into plant-available forms through the action of these enzymes. Phosphatase is of particular importance under conditions of low phosphorus availability which is commonly found in pinon-juniper soils. Acid and alkaline phosphatase activities (mg...

introduction : deproteinized bovine bone mineral (bio-oss) is a xenogenic bone substitute, widely used in maxillofacial bone regeneration. the aim of this in vitro study was to investigate its influence on the growth behavior of human osteosarcoma cell line, saos-2 culture, and compare it with the physiologic dose of dexamethasone, an inductive factor for osteoblasts. materials and methods: hum...

Because dietary acid increases renal secretion of endothelin-1 (ET-1) which is synthesized by renal microvascular endothelium, we examined if reduced extracellular pH increases ET-1 secretion by cultured human renal microvascular endothelial cells (RMVECs). Confluent cells were exposed to serum-free media for 24 h, then incubated in either control, acid, or alkaline serum-free media for 12 h. S...

background: vanadium is an important environmental and industrial pollutant. it has a status of reproductive toxicant and is reported to cross placental barrier. objective: the current study was performed to assess the therapeutic efficacy of tiron and its combination with selenium against vanadium induced toxicity in lactating and suckling rats. materials and methods: rats were exposed to vana...

There are no studies comparing some of the most important markers, such as vitamin D, parathormone, osteocalcin, bone alkaline phosphatase, and calcium, in patients with chronic benign and malignant pancreatic diseases. Our objective was to comparatively evaluate serum markers of bone metabolism in patients with chronic pancreatitis and in those with ductal pancreatic adenocarcinoma. Sixty-thre...
