DRM (detergent-resistant membranes), which are resistant to solublization by non-ionic detergents, have been demonstrated to be involved in many key cell functions such as signal transduction, endocytosis and cholesterol trafficking. Covalent modification of proteins by fatty acylation has been proposed to be an important protein-targeting mechanism for DRM association. However, little is known...

Magnesium phosphate cements (MPC) are the most developed kind of chemically bonded ceramics which form through the reaction of magnesium oxide and soluble phosphate salts. Therefore, study of different magnesium phosphate cement systems is considered important according to the type of phosphate agent used. In this study, effect of mono-ammonium phosphate (MAP), di-ammonium phosphate (DAP), and ...

Adenylate cyclase [atp pyrophosphate-lyase (cyclizing): EC 4.6.4.4] activities were examined in mouse LM cell (fibroblast) membranes that were supplemented with ethanolamine and/or fatty acids. The supplements were incorporated into the plasma membrane phospholipids in significant amounts. Fatty acid supplementations had distinct effects as compared to polar head group supplementations. All lip...

Red Amaranth (Amaranthus tricolor) and green Amaranth (Amaranthus viridis) are two very important leafy vegetables consumed in most parts of India, not only for their flavours, but also for their pharmacological activities. The cooking processes are different in the different part of this country, and therefore, the present study was designed to analyze their in vitro antioxidant profile before...

Thyroglobulin, the precursor of thyroid hormones, is extracellularly stored in a highly condensed and covalently cross-linked form. Solublization of thyroglobulin is facilitated by cysteine proteinases like cathepsins B and K which are proteolytically active at the surface of thyroid epithelial cells. The cysteine proteinases mediate the processing of thyroglobulin by limited extracellular prot...

The purpose of this study was to evaluate the spatial changes of groundwater phosphate concentrations using geostatistical methods based on data from 10 groundwater wells. One of the conventional tools in decision making on the groundwater management is geostatistical method. To evaluate the spatial changes of phosphate concentrations in groundwater, the universal kriging method with cross-vali...

abstract many agricultural researches have been performed to improve soil productivity. nitrogen (n) and phosphorus (p) are essential elements which are utilized by the plants in large amounts. phosphorus can be provided by applying chemical fertilizers. microorganisms convert insoluble phosphate to the soluble form and some bacteria such as rhizobacteria play an important role in this process....

a simple, sensitive and accurate method for spectrophotometric determination of dalacinphosphatehas been established. the method is based on the reduction of atomic absorptioncalcium ion by phosphate. because, there is a phosphate mole in every dalacin mole structureand with measurement of phosphate, dalacin is beyond measurement too. therefore, the reactionbetween acidic hydrolysis products of...
