BACKGROUND AND OBJECTIVES Recent in vitro studies have shown a link between alkaline phosphatase and vascular calcification in patients with chronic kidney disease (CKD). High serum levels of alkaline phosphatase are associated with increased death risk in epidemiologic studies of maintenance hemodialysis (MHD) patients. We hypothesized that coronary artery calcification is independently associ...

Background: The most frequent sites of metastases in prostatic carcinoma are bones. Bone scintigraphy is the diagnostic tool of first choice for staging bone metastases in cancer of the prostate. But this examination is expensive and time-consuming.Therefore we are looking especially for serum parameters like alkaline phosphatase, the isoenzyme of bone-specific alkaline phosphatase, and prostat...

soil enzyme activities can be used as indicators of soil quality for assessing the sustainability of agricultural ecosystems. the objective of this study was to determine the effects of barley residue input rate, burning, urea fertilizer and tillage management on activities of alkaline phosphatase and urease under field conditions, after a period of 90 days. the experiment was carried out based...

This study investigated the effects of replacing commercial feeds with fresh black soldier fly larvae (BSFL) on immune enzyme activities, water quality in culturing environment, and intestinal microbiota Pacific white shrimp ( Litopenaeus vannamei ). Five different feeding regimes were designed, which 0% (control group), 25%, 50%, 75%, 100% replaced equal wet weight BSFL, respectively. The expe...

Bile duct ligation causes a five- to sevenfold increase in the activity of rat liver alkaline phosphatase within 12 hours after ligation and a similar rise in the activity of alkaline phosphatase in serum. The increased serum activity is due entirely to the appearance of a new isoenzyme that has the properties of rat liver alkaline phosphatase. The increase in both serum and liver alkaline phos...

Serum total alkaline phosphatase is the most commonly used biochemical marker of bone disease in renal patients, but alkaline phosphatase originates from different organs and sometimes lacks specificity. Bone isoenzyme measurement is considered superior to total alkaline phosphatase for the assessment of bone metabolism. We have studied the value of bone isoenzyme, determined by a new. IRMA (Ta...

Background: Collagen, the most abundant protein in the human body, and as an extracellular matrix protein, has an important role in the fiber formation. This feature of the collagen renders  establishment of the structural skeleton in tissues. Regarding specific features associated with the collagen, such as, formation of the porous structure, permeability and hydrophilicity, it can also be use...

alkaline phosphatase is an enzyme with widespread use in research and industry such as protein labeling, dephosphorylation of nucleic acids, and enzyme based biosensors. in the present study, alkaline phosphatase gene was inserted into the pet15b vector. the recombinant dna was then expressed using iptg as an inducer. the expression of this enzyme was optimized by changing expression conditions...

The total alkaline phosphatase levels were determined in 118 patients with adult coeliac disease, 65 of whom had evidence of osteomalacia.The secretor and blood group status, intestinal isoenzyme, and liver alkaline phosphatase played no significant part in the levels of serum alkaline phosphatase found. There was a significant correlation between the levels of serum alkaline phosphatase and th...

Using immunochemical techniques, alkaline phosphatase isoenzymes were determined in tissue samples of breast carcinomas and carcinomas of the gastrointestinal tract. In breast carcinomas only 19% of the patients expressed significant placental alkaline phosphatase activity, compared with 78% in gastrointestinal tumours. The intestinal isoenzyme was found in 50% of the breast carcinomas and in n...
