biomimetic method was used to apply hydroxyapatite (ha) coating onto ti6al4v cylinders. this process is a physicochemical method in which a substrate is soaked in a solution simulating the physiological conditions, for a period of time enough to form a desirable layer of the calcium phosphate on the substrate. in the present study, specimens were soaked in 5, 10 m solutions of naoh at temperatu...

some biochemical characteristics of common carp (cyprinus carpio) and silver carp (hypophtalmichthys moltrix) surimi prepared by a conventional washing method and protein isolated using alkaline-acid-aided processes were investigated. solubility of protein in silver carp and common carp were found to be highest by using the conventional washing method. decreases in myoglobin and lipid contents ...

Alkaline stress (high pH) severely damages root cells, and consequently, inhibits rice (Oryza sativa L.) seedling growth. In this study, we demonstrate the accumulation of reactive oxygen species (ROS) in root cells under alkaline stress. Seedlings of two rice cultivars with different alkaline tolerances, 'Dongdao-4' (moderately alkaline-tolerant) and 'Jiudao-51' (alkaline-sensitive), were subj...

Gastric alkaline secretion was determined in ranitidine treated healthy subjects and duodenal ulcer (DU) patients using gastric perfusion aspiration system and back titration of gastric perfusate to original pH 6.0. Basal alkaline secretion showed periodic fluctuations reaching peaks at phase III of the migrating motor complex (MMC) in the stomach. Mean basal alkaline secretion in healthy norma...

Two members of a placental alkaline phosphatase (PLAP) family, PLAP and PLAP-like or germ cell alkaline phosphatase, are aberrantly expressed in tumors of ecotropic origin. To characterize alkaline phosphatase induced in seminoma, alkaline phosphatase cDNA clones were isolated from a cDNA library constructed from seminoma cells and characterized by nucleotide sequence determination. Thus, isola...

date syrup powder is a new product which can be used as sugar substitute. first, the date syrupwas spread out on a foil and placed in the oven at 60°c for 24 hours. date syrup was separated from the foil andgrinded. 2% agar and 2% starch were added and syrup with agar and starch that was in a lumpy shape werecrushed and spread on the foil and placed at 60°c for 24 hours. powdered granules, agar...

the aim of this study was to clone the serine alkaline protease-encoding gene from bacillus subtilis 168. this protease, which can have many applications especially in detergent, may be industrially an important enzyme. for the amplification of the gene, pcr was performed with a pair of primers specifically designed for this purpose. electrophoresis of the pcr product showed the expected band o...

introduction: the aim of this study was to evaluate the compressive strength of calcium-enriched mixture (cem) cement in contact with acidic, neutral and alkaline ph values. methods and materials: the cement was mixed according to the manufacturer’s instructions, it was then condensed into fourteen split molds with five 4×6 mm holes. the specimens were randomly divided into 7 groups ( n =10) an...

Macromolecular alkaline phosphatase (EC 3.1.3.1) was found in the serum of a patient suffering from myasthenia gravis (adult type II) complicated with thymoma, and was shown by immunoelectrophoresis to be bound to immunoglobulins A and G (IgG). Placental alkaline phosphatase, complexed with either the patient's serum or IgG purified from the patient's serum, remained at the origin on electropho...
