Due to the fact that many application processes take place at different temperature, better examining and understanding of swelling properties as a function of temperature is essential for such application. The temperature effect on the swelling properties of commercial polyacrylic acid (PAA) hydrogel beads was investigated as a function of time and temperature. Gel bead size, swelling equilibr...

Hereditary angioedema (HAE) is a rare, life-threatening, autosomal dominant disease characterized by recurrent episodes of angioedema, and caused by a deficiency of the plasma protein C1-esterase inhibitor (C1-INH). Clinical manifestation of HAE may first develop during childhood but typically presents around puberty with nonpruritic and non-pitting edema of the subcutaneous and mucosal tissues...

Sunhinary. A survey has been ii)ade of the p)rol)erties of cori wlitoc(hon(rlia in .swelling and contraction. The mitochoni(lria swell spontalneouisly in KCl but not in sucrose. Aged mitochondria will swell rapidly in sucrose if treate(l Nvith citrate or ED'FA. Swelling does not impair oxidative phosphorylation if bovine ser-niiii albumin is p)resellt. Contraction can be maintained or initiated...

BACKGROUND Vibratory angioedema (VA) is a rare physical urticaria, with symptoms of itching and swelling of the skin or mucosa when it is exposed to vibration. Avoidance of vibration is the best way to manage this condition. This case report will assist physicians to diagnose this rare condition. Here, a previously unpublished potential successful treatment modality is being presented, with goo...

The role of the GABA transporter in acute toxicity in chick retina due to metabolic inhibition was investigated by the use of several substrate (nipecotic acid, THPO) and nonsubstrate (SKF 89976A, NO711) GABA transport inhibitors. Metabolic stress-induced acute toxicity in the retina is characterized by swelling of distinct populations of retinal neurons and selective release of GABA into the m...

Volume-sensitive K-Cl cotransport occurs in red blood cells of many species. In intact cells, activation of K-Cl cotransport by swelling requires dephosphorylation of some cell protein, but maximal activity requires the presence of intracellular ATP. We have examined the relation between K-Cl cotransport activity and ATP in ghosts prepared from human red blood cells. K-Cl cotransport activity i...

expansive behavior is usually observed in soils, which contain fractions of clay minerals in their composition. water absorption of clay particles and change of natural water content of soil up to plastic limit and down to shrinkage limit will cause significant volume change in expansive soils and will result in severe damages to the structures, buildings and foundations. swelling potential is ...

cotton fibres were subjected to cleaning process and then characterized for maturity. decrystallisation and swelling processes with caustic soda, ethanol, propan-2-ol and trichloroethene on the native fibres were carried out. the effects of these on the strength and moisture regain were investigated. the activation energies of the dyeings were also analysed with durazol scarlet red 4 bas. the r...

using controlled drug delivery devices is one of the novel methods of drug delivery which is used to perform drug therapy with the minimum side effects. mucoadhesive polymers are one of these devices. chitosan is a natural polymer which is a suitable candidate for this purpose due to it is biocompatibility, bioadhesion and high capability to adsorb peptide drugs. since gi tract has both acidic ...
