Synthetic polymer was exploited as water-superabsorbent hydrogel and helped to conserve water in the agricultural soil. The hydrogel polymers were synthesized the carboxymethyl cellulose (CMC) and starch in addition to SiO2 nanoparticles. Superabsorbent hydrogel polymer having 35% water retention ability was analyzed with three replicates. Hydrogel increased the water restoration capability of ...

Novel drum-like Cd(OH)(2) superstructures with uniform size were synthesized on a large scale through a facile one-pot hydrothermal route with the co-existence of ammonia and biopolymer sodium carboxymethyl cellulose solutions.

A cytokinin-binding protein has been isolated from wheat germ via ammonium sulfate precipitation, carboxymethyl Sephadex chromatography, and affinity chromatography on a column substituted with a derivative of kinetin riboside. On Sephadex G-200, the protein migrated with an apparent molecular weight of 122,000 daltons. The dissociation constant for kinetin was determined by equilibrium dialysi...

The tryptic peptides of reduced, S-carboxymethyl CI chain of bovine luteinizing hormone have been isolated by gel filtration and electrophoresis or chromatography on paper. The amino acid compositions of all peptides are identical with those of the OL chain of thyroid-stimulating hormone (TSH), whose sequence is described in the preceding communication. Chymotryptic-like cleavages also yielded ...

The purification from bovine pituitary gland of a growth factor responsible for the control of animal cell division in tissue culture is reported. This growth factor is a polypeptide of 13,300 molecular weight and is homogeneous when analyzed by polyacrylamide gel electrophoresis, carboxymethyl-Sephadex gradient elution chromatography, and Sephadex G-50 chromatography. The yield of growth facto...

Three extracellular cellulose-depolymerizing enzymes from cotton undergoing decay by the brown rot fungus Meruliporia (Serpula) incrassata were isolated by anion-exchange and hydrophobic interaction chromatographies. Depolymerization was detected by analyzing the changes in the molecular size distribution of cotton cellulose by high-performance size-exclusion chromatography. The average degree ...

The aim of the study was to produce a model form of a drug of anti-inflammatory activity designed for application in oral cavity. An attempt was made to choose hydrogel vehicle which would ensure not only high pharmaceutical availability of the therapeutic agent but appropriate theological properties of the drug as well. Variant prescriptions with ketoprofen were worked out which differed in th...

The viscosity distribution of the liquid around a rising bubble in carboxymethyl cellulose (CMC) aqueous solutions was measured experimentally by particle image velocimetry (PIV). The effect of the concentration of CMC solutions on the viscosity distribution around a bubble and the coupling relations between the viscosity field, flow field and shear stress field were also studied. Results indic...

OBJECTIVE This study examines the effect of various wound dressings on the pH levels of a wound, using a simulated wound environment. METHOD The pH levels of a 4 different wound dressings (manuka honey dressing, sodium carboxymethylcellulose hydrofiber dressing, polyhydrated ionogen-coated polymer mesh dressing, and a protease modulating collagen cellulose dressing) were tested in a simulated...
