Ocular drug delivery is a very challenging area for ophthalmologists and scientists due to the structural barrier complexity of eye. Barriers such as different layers cornea, sclera, conjunctival blood flow, tear dilution limit efficacy anterior part eye in addition more barriers present posterior part. Due these, have designed studied various systems increase treatment Among conventional ocula...

Conventional transdermal drug delivery systems (TDDS) have been designed for drug delivery through the skin. These systems use the permeability property of stratum corneum, the outermost surface layer of the skin. Applying polymeric micro and nanofibers in drug delivery has recently attracted great attention and the electrospinning technique is the preferred method for polymeric micro-nanofiber...

mucosal surfaces of the body provide a universal entry portal for all known and emerging infectious pathogenic microbes. therefore, it seems that special vaccination strategies are needed for vaccines that can hinder the entry capability of pathogenic microbes through the mucosal surfaces. lactic acid bacteria are widely used in the food industry and are presently applied as delivery vehicles i...

background: in radiation treatment of moving targets located in thorax region of patient body, the delivered dose does not match with the planned treatment, resulting in some over and under dosage in the tumor volume, as a function of motion magnitude and frequency. several efforts have been done to investigate the target motion effects on dose distribution in the target and surrounding normal ...
