Microencapsulation has become a common technique in the production of controlled release dosage forms. Many results have been reported, concerning the use of alginate beads as controlled release drug formulations. Alginate has a unique gel-forming property in the presence of multivalent cations, in an aqueous medium. Ibuprofen is an excellent analgesic and antipyretic, non-steroidal anti-inflam...

BACKGROUND Diphtheria and tetanus toxoid combined with acellular pertussis (DTaP) vaccines are less reactogenic than diphtheria and tetanus toxoid combined with whole cell pertussis (DTwP) vaccines. However, local reactions increase in rate and severity with each successive DTaP dose, and swelling of the entire injected limb has been reported after booster doses. METHODS We reviewed reports o...

Elastic therapeutic tape is gradually being used more in clinical physiotherapy and sports activities. Many studies have been published regarding its effects on diverse symptoms and their results are of great importance to clinicians and researchers. I read with great interest the recent study published in the Journal of Physiotherapy entitled ‘Kinesio Taping does not decrease swelling in acute...

expansible soils are those which will suffer considerable swelling and volume change when subjected to water. the resulting swelling pressure may cause complete destruction of such light structures as irrigation canal linings, floor slabs, etc. based upon previous investigations, swelling of clayey soils has been blamed for failure of many irrigation canals in iran and in other countries of the...

Several years ago it was observed that strict anaerobiosis prevented the swelling of isolated liver mitochondria. This was true for spontaneous swelling and for swelling induced by phosphate, certain metal ions, and other substances (l-3). This observation created a sharp paradox with the generally accepted view that adenosine triphosphate or active phosphorylation was essential in maintaining ...

This study examined the interrelated effect of environmental pH, gelatin backbone modification and crosslinking modality on hydrogel morphology, surface hydrophilicity, in vitro swelling/degradation kinetics, in vitro drug release kinetics and in vivo degradation, inflammatory response and drug release activity. The percent glutaraldehyde fixation had a greater impact on the morphology of the d...

Electroporation has been widely accepted as an important tool for the delivery of exogenous molecules into cells. Previous mechanistic studies have been carried out by observing either the average behavior from a large population of cells or the response from a small number of single cells. In this study, we demonstrated a novel microfluidic method with high throughput (up to 30 Hz) for real-ti...

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...
