agent technology is an emerging and promising research area in software technology, which increasingly contributes to the development of value-added information systems for large healthcare organizations due to its capability to automatically modify themselves in response to changes in their operating environment. multi agent system (mas) approach is the construction of a complex system as a se...

SJG-136 (NSC 694501) is a novel DNA cross-linking agent that binds in a sequence-selective manner in the minor groove of the DNA helix. It is structurally novel compared with other clinically used DNA cross-linking agents and has exhibited a unique multilog differential pattern of activity in the NCI 60-cell line screen (i.e., is COMPARE negative to other cross-linking agents). Given this profi...

Purpose: To evaluate g-H2AX foci as a pharmacodynamic marker for DNA damage induced by DNA interstrand cross-linking drugs. Experimental Design: g-H2AX foci formationwas validated preclinically in comparisonwith the Comet assay, and evaluated pharmacodynamically in two phase I studies of different dosing schedules of the novel cross-linking agent SJG-136 (SG2000). Results: The measurement of g-...

  During last two decades, polysaccharides such as alginate (Alg) alone and in combination with other biopolymers are widely used in vaccine and drug delivery systems. The aim of the present work was to investigate the potential utility of microparticles made of alginate (Alg) as new vehicles for improving nasal vaccine delivery. For this purpose, diphtheria toxoid (DT) was chosen as a model an...

Chitosan and gelatin were used as polymer scaffolds for cartilage tissue engineering. The scaffold was a biodegradable drug delivery system diclofenac sodium to treat defects on osteoarthritis (OA). materials composed of sodium, chitosan, gelatin, cross-linking agent-glutaraldehyde (GTA) form scaffold. purpose this study investigate the effect GTA concentration variations (0.00%; 0.25%; 0.50%; ...

Microencapsulation with hydrocolloids as a modern technique has been used to prolong the survival of probiotics during exposure to harsh conditions. In this study, alginate-Hylon starch microcapsules with genipin cross-linked chitosan and poly-L-lysine coatings were developed to encapsulate four strains of probiotic bacteria, including Lactobacillus casei (ATCC 39392), Bifidobacterium bifidum (...

Abstract Background Nanoparticulate drug delivery systems have attracted significant attention in the field of cancer nanotechnology. This study determines the effect of folate-based Fe2O3 nanoparticles. This study aimed to decorate nanoparticles with folate (FA), a molecular ligand for ‘active’ targeting of cancerous cells and the application of modified-nanoparticles in cancer treatment. ...
