Introduction: COVID-19 affects the liver, causing alteration in liver biochemistry tests such as aspartate transferase (AST), alanine (ALT), alkaline phosphatase (ALP), total bilirubin and albumin. Objective: To determine prevalence of functions associated factors for severity among Peruvian patients. Materials methods: A descriptive, retrospective cross-sectional study was performed 4 public h...

Serum alkaline phosphatase (ALP) concentration is a prognostic factor for osteosarcoma in multiple studies, although its biological significance remains incompletely understood. To determine whether gene expression patterns differed in osteosarcoma from patients with differing serum ALP concentrations, microarray analysis was performed on 18 primary osteosarcoma samples and six osteosarcoma cel...

This two-site IRMA includes specific monoclonal antibodies for measuring skeletal alkaline phosphatase (B-ALP) in human serum. Assay calibration is based on mass units (micrograms per liter) and was established with purified B-ALP from a human osteosarcoma cell line, SAOS-2. Precision studies demonstrated intra- and interassay CVs of 3-5% and 5-7%, respectively. Relative reactivity studies show...

Bone-specific alkaline phosphatase (BAP) synthesized by osteoblasts is a highly sensitive and specific marker of the boneforming activity. Paget’s disease is the most common cause of elevated serum BAP. Other causes include osteomalacia, rapid bone loss, bone growth, healing fracture, acromegaly, hyperthyroidism, osteogenic sarcoma, bone metastases, leukemia, myelofibrosis, and rarely myeloma. ...

The content of alkaline phosphatase (ALP) was determined in neutrophils isolated from patients with acute bacterial infections by a standard enzyme assay. Compared with control cells, patient cells exhibited about a fivefold increase in ALP activity. There was no difference between the ALP Km values of control and patient cells, which indicates that the elevated activity in patient cells was du...

BACKGROUND AND PURPOSE Higher serum alkaline phosphatase (ALP) and phosphate levels are associated with atherosclerotic disease and an increased risk of cardiovascular events. However, the association of ALP/phosphate with cerebral atherosclerosis and prognosis in patients with acute stroke is not well known. METHODS In 1034 patients with first-ever acute cerebral infarction, levels of ALP an...

The alkaline phosphatase (ALP) assay is a rapid and convenient method for verifying milk pasteurization. Since colorimetric ALP assays rely on subjective visual assessments, their results are especially unreliable near the detection limits. In this study, we attempted to establish quantitative criteria for residual ALP in milk by using a more objective method based on spectrophotometric measure...

A novel alkaline phosphatase (S-ALP) was found in the culture filtrate of Streptomyces hiroshimensis IFO 12785. Purification was achieved on Sephadex G-75 column, palmitoylated gauze column, and Superdex 75 HR column chromatographies. The molecular weight of S-ALP was estimated to be 14200 by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The isoelectric point is 9.2. S-A...

We studied the temporal and quantitative relation between bone alkaline phosphatase (ALP) and height velocity in 62 short normal children as part of a prospective randomized study to compare placebo, growth hormone, oxandralone, and testosterone, singly and in combination, in promoting short-term growth acceleration and increased final height. The pretreatment cross-sectional correlation betwee...

Oesophageal cancer is endemic in some regions of the Islamic Republic of Iran and efforts have made to find factors that play a role in its prognosis. We retrospectively examined the correlation of serum alkaline phosphatase (ALP) levels with several clinicopathological characteristics of 207 cases of oesophageal carcinoma. The mean ALP level in patients with lymph node involvement was signific...
