The aim of this study is to formulate a novel ophthalmic nanosuspension (ONS), an alternative carrier system to traditional colloidal carriers for controlled release (CR) of acyclovir (ACV). In the present study, ONS is employed to avoid some of major disadvantages of colloidal carriers systems such as instability in cul de sac and short half life by increasing efficiency of drug encapsulation ...

Recombination of excess (nonequilibrium) electrons and holes in semiconductors through impurity recombination centers (traps) known as trap-assisted (ShockleyRead-Hall) recombination is in many cases the dominant process. In this chapter, we develop the general theory of trap-assisted recombination and study in detail two key characteristics: (1) dependences of excess charge carriers’ lifetime ...

Here we present a continuous molecule separation/concentration system using flowing microbubbles as carriers. Microbubbles continuously generated at the microchannel confluence are able to capture target substances dissolved in the liquid phase, and these bubble carriers are concentrated by continuously removing liquid phase from the stream to achieve the continuous molecule separation. In the ...

biopolymer based nano-complex is a category of nano-carriers which are produced by interaction between protein and polysaccharide. they can carry hydrophobic nutriciuticals in aqueous solutions and also cause to increase of protection and bioavailability of encapsulated active materials. in this research, gellan-caseinate complexes containing omega3 were produced by adding gellan solutions to c...

hepatitis c virus (hcv) infection causes chronic hepatitis, which frequently leads to hepatic fibrosis and hepatocellular carcinoma (hcc). alanine aminotransferase (alt) is a biomarker of hepatocyte injury and is associated with the progression of hepatic fibrosis. advanced hepatic fibrosis also predisposes hcv carriers to a risk of hcc. in contrast, some cases with persistent hcv infection hav...
