introduction safflower (carthamus tinctorius l.) is an important oilseed crop grown throughout the semiarid regions in many parts of the world. it has been cultivated for its oil and flowers and as a meal. alkaline stress is caused by alkaline salts such as na2co3 or nahco3 in the soil. alkaline stress, is widespread environmental constraint affecting crop productivity ,which can inhibit absorp...

Single-cell alkaline phosphatase (AP) activity is being increasingly used to characterize phosphorus (P) status of individual species of phytoplankton. As phytoplankton growth rates depend more directly on the internal rather than external P concentrations, we determine the AP activity in the two species of freshwater phytoplankton, Scenedesmus quadricauda (Turpin) Bréb. and Asterionella formos...

Plasma alkaline phosphatase activity was measured in 349 infants aged between 5 and 10 days to establish a normal range for different gestational ages. Significant differences were observed between term and preterm infants, the highest values being associated with the shortest lengths of gestation. Plasma calcium, phosphate, and alkaline phosphatase activity were measured sequentially in 51 pre...

In this work, automatic pH changing system on lab-on-paper devices for enzyme-linked immunosorbent (ELISA) has been developed in order to improve their sensitivity and make the technique much more applicable to real samples. The most widely used enzyme in immunoassay are alkaline phosphatase (ALP) and peroxidase. ALP-conjugated secondary detection with BCIP/NBT substrate provides high sensitivi...

This study was aimed to determine the alkaline phosphatase activity following time course (days) in the intestine of broilers. We used a sample of 54 subjects of broilers from hatching period to 56th day of age. Our finding showed a significant increase in the alkaline phosphatase activity at various levels in the different intestinal segments during the first two weeks of life and then decreas...

The neutrophilic alkaline phosphatase activity of 40 newborns was determined and found to be frequently raised, similarly to a leukaemoid reaction. The newborn neutrophil has strong alkaline phosphatase activity and is unlike the myeloid leukaemia cell which has no alkaline phosphatase activity.

OBJECTIVE To determine whether serum vitamin D levels are correlated with serum levels of alkaline phosphatase or not. STUDY DESIGN Cross-sectional, observational study. PLACE AND DURATION OF STUDY Multi-centre study, conducted at Liaquat National Hospital and Medical College, National Medical Centre and Medicare Hospital, Karachi, from January to October 2009. METHODOLOGY Patients attend...

As two important physico-chemical parameters, the acidic and alkaline residues of protein are of evident significance for the evaluation of protein properties and the design of relevant separation and analysis. However, there is still no electrophoretic method used for the direct detection of free acidic and alkaline residues of protein. Herein, we developed the concepts of moving reaction boun...

Exposure of Saccharomyces cerevisiae to alkaline pH provokes a stress condition that generates a compensatory reaction. In the present study we examined a possible role for the PKA (protein kinase A) pathway in this response. Phenotypic analysis revealed that mutations that activate the PKA pathway (ira1 ira2, bcy1) tend to cause sensitivity to alkaline pH, whereas its deactivation enhances tol...
