in recent years, encapsulation of drugs and antigens in hydrogels, specifically in calcium alginate particles, is an interesting and practical technique that was developed widespread. it is well known that alginate solution, under proper conditions, can form suitable nanoparticles as a promising carrier system, for vaccine delivery. the aim of this study was to synthesis alginate nanoparticles ...

objective: intravascular catheter-associated infection has been increasing hospitalization in post-surgery patients mainly due to microbial colonization of the catheter surface and formation of a superficial biofilm layer. the present study is aimed in developing an effective antibacterial device which can prevent colonization of organisms by modification of catheter. methods: in the present st...

Regulation of IgE production by antigen in a primed murine splenic lymphocyte culture system was described. Maximum IgE antibody production was found to occur when cells were cultured in the absence of exogenously added antigen. A cells and T lymphocytes did not affect the production of anti-DNP IgE antibody. By using a hapten-carrier antigen system (DNP-EA) for priming mice in vivo, it was fou...

Cultures of adipose tissue explants are a valuable tool for studying the intracellular mechanisms involving hormones and nutrients. However, testing how fatty acids affect cells requires a carrier molecule; bovine serum albumin (BSA) has been used for this purpose. However, contaminants can alter the cellular response. Our objectives were to: 1) test BSA as a fatty acid carrier and 2) evaluate ...

We have examined the carrier-specific helper activity of a number of antigen-specific, I region-restricted T cell hybridomas prepared in our laboratory. The hybridomas were assayed for helper activity in the presence or absence of exogenously added nonspecific factors found in the concanavalin A-activated supernatants of normal mouse spleen cells. Of six hybridomas tested, all six could stimula...

Skeletal uptake of radiolabeled-1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetramethylene phosphoric acid (e.g., 177Lu-DOTMP) complex, is used for bone pain palliation. The moderate energy of β-emitting 177Lu (T½ = 6.7 d, Eβmax = 497keV) has been considered as a potential radionuclide for development of the bone-seeking radiopharmaceutical. Since the specific activity of the radiolabeled car...

A new transistor architecture is developed by reusing already existing fabrication process bricks in an embedded non-volatile memory (eNVM) sub-40 nm CMOS technology, resulting a middle-voltage zero-cost transistor, ideal for low-cost products. TCAD simulations are undertaken to confirm the feasibility of optimization and predict performance reliability. The fabricated then electrically charact...
