Functional multilayer thin films have been prepared by layer-by-layer (LbL) deposition for the development of sensors, separators, and drug delivery systems. In particular, glucose-sensitive LbL films have been widely studied for use as glucose sensors and in glucose-triggered drug delivery systems. In this work, I report on glucose-sensitive LbL films that consist of concanavalin A (ConA), phe...

cinema as a cultural industry, is the promoter of identity, memory, dreams and collective projects. mexico has introduced its collective identity to the world, using this industry. examining the application of this industry in mexican cinema can be considered an important step for improving the country’s cinema. approaches to the origins of modern nations consider culture as a fundamental const...

Emergency departments are facing increasing drug-related health problems with difficult medicolegal and social consequences. A 25-year-old male no past medical history arrived at our emergency department. He was brought to the room of hospital by security forces, as he suffered a gunshot wound while traveling place. The cocaine-filled capsule seen on plain abdominal film. film is most commonly ...

In this article, a carbon nanotube (CNT) array-based system combined with a polymer thin film is proposed as an effective drug release device directly at cellular level. The polymeric film embedded in the CNT array is described and characterized in terms of release kinetics, while in vitro assays on PC12 cell line have been performed in order to assess the efficiency and functionality of the en...

It is possible to alter the permeability of ethyl cellulose membrane with certain materials such as surfactants. In this study the effect of surfactant concentration and different HLB values on the release rate of atenolol from ethyl cellulose-coated tablets was evaluated. The results showed that when the concentration of surfactant increased, the rate of drug release also increased. The kineti...

Water soluble polymers such as Hydroxy Propyl Methyl Cellulose (HPMC), Poly Vinyl Pyrrolidone (PVP), Carboxy Methyl Cellulose Sodium (CMC Na), and Methyl Cellulose as well as in combination of varying proportions are used in this study for the protective coating of Microcrystalline Hydroxy Apatite Complex (MCHC). The objective of this study was to investigate the effect of aqueous film coating ...

The HIV-1 replication inhibitor dapivirine (DPV) is one of the most promising drug candidates being used in topical microbicide products for prevention of HIV-1 sexual transmission. To be able to block HIV-1 replication, DPV must have access to the viral reverse transcriptase enzyme. The window for DPV to access the enzyme happens during the HIV-1 cellular infection cycle. Thus, in order for DP...

Introduction: Orodispersible films (ODF) is a thin strip that mostly transparent, biodegradable and it has hydrophilic polymers disintegrate dissolves immediately when getting in contact with saliva. Different disintegrants play crucial role film properties such as organoleptic properties, thickness, particular disintegration time of the film. The main reason for development oral their prominen...
