The survival probability of immobile targets annihilated by a population of random walkers on inhomogeneous discrete structures, such as disordered solids, glasses, fractals, polymer networks, and gels, is analytically investigated. It is shown that, while it cannot in general be related to the number of distinct visited points as in the case of homogeneous lattices, in the case of bounded coor...

Gel becomes an important class of soft materials since it can be seen in a wide variety of the chemical and the biological systems. The unique properties of gel arise from the structure, namely, the three-dimensional polymer network that is swollen by a huge amount of solvent. Despite the small volume fraction of the polymer network, which is usually only a few percent or less, gel shows the ty...

Celecoxib is used in the treatment of osteoarthritis, rheumatoid arthritis, acute pain, joint inflammation and sport injuries. Long term administration of the drug results in such complications as gastrointestinaland renal disturbances and cardio-vascular complications. The main objective of the present study was to investigate the feasibility of delivering celecoxib incorporated in gel formula...

Apparatus necessary for a quantitative gel diffusion and precipitation assay of duck hepatitis virus was designed and constructed.

Ellner, Paul D. (University of Vermont, Burlington) and Carolyn D. Bohan. Serology of the soluble antigens of Clostridium perfringens types A-F by agar-gel diffusion. J. Bacteriol. 83:284-296. 1962.-A serological study by agar-gel diffusion of the soluble antigens of 39 strains of the Clostridium perfringens group has shown them to be extremely heterogeneous. Strain variation occurred within th...

A comparison is made of tests for thyroglobulin antibody, using gel diffusion, electroprecipitin, bentonite flocculation, tanned red cell agglutination, and latex slide agglutination techniques on sera from cases of Hashimoto's disease and other thyroid disorders. Any increase in gamma globulin was also noted from the serum electrophoretic pattern. The gel diffusion and electroprecipitin tests ...

A practical immunologic assay to detect the hormone, prolactin, in body fluids was evaluated. Prolactin content was assayed using positive antiprolactin sera prepared in rabbits and test samples of serum, urine, and urinary extract from a borane exposed female monkey in micro-Ouchterlony gel diffusion and agglutination inhibition tests. The gel diffusion test gave qualitative results while the ...

The counterimmunoelectrophoresis (CIE) technique was developed as a diagnostic procedure for ram epididymitis caused by Brucella ovis. CIE test results with sera from naturally and experimentally infected male sheep compared favorably with those obtained by gel diffusion and complement fixation employing the same B. ovis surface R antigen. The main advantage of CIE over gel diffusion consists i...

Removing the bacteria, including Enterococcus faecalis, from the root canal is one of the important aims in endodontic treatment.We aimed to compare the antibacterial activity of Chlorhexidine with two natural drugs. The antibacterial activities of three different propolis extracts (alcohol concentrations: 0, 15, 40%) and Aloe vera gel on E. faecalis were compared using three methods: disk diff...

PURPOSE A niosome based transdermal drug delivery system of Nimesulide (NIM) was developed and extensively characterized and evaluated for in-vitro performance followed by in-vivo evaluation in rats by carrageenan induced rat paw edema method. METHOD Niosomes were prepared by lipid film hydration technique using tweens and spans. Preparation of niosomes was optimized for highest percent drug ...
