Objective(s): Researchers have intended to reformulate drugs so that they may be more safely used in human body. Polymer science and nanotechnology have great roles in this field. The aim of this paper is to introduce an efficient drug delivery vehicle which can perform both targeted and controlled antibiotic release using magnetic nanoparticles grafted pH-responsive polymer.<s...

The objective of research was to explore the suitability of lipids like compritol 888 ATO and stearic acid as release retardant to develop sustained release (SR) tablets. The SR micromatrices of lipid (s) and glipizide were prepared (LM1- LM6) as intermediate product by fusion method and assessed for various pharmacotechnical properties. Micromatrices were formulated as SR tablets (F1-F6) by di...

In this study, the synthesis, characterization and controlled release behavior of new Hollow Silica Nano particles (HSNPs) and Magnetic Silica Nano Particles (MSNPs) were studied. Magnetic Silica Nano particles (MSNPs), as drug delivery vehicles, were synthesized through the coating of Fe3O4 nano-crystals with silica layers. The HSNPs were obtained by removal of Fe3O4 templates with hydrochlori...

Considering the importance of determining potential hazards and factors that can cause anunexpected fire and due to the important role of nanotechnology to achieve more effectiveproperties, this paper presents our experiments on preparing nanocomposites based onPoly(ethylene terephthalate)(PET) and montmorillonite (MMT) as organoclay via meltblending with different clay loadings to investigate ...

This study investigates the link between incarceration and health behavior among a sample of young adults from the National Longitudinal Study of Adolescent Health (N = 1,670). The association is analyzed using propensity score methods and a strategic comparison group: respondents who have been convicted of crimes, but not incarcerated. Findings suggest that former inmates consume more fast foo...

semelil is an herbal-based compound which is used for the treatment of chronic wounds, especially diabetic foot ulcers. on the other hand, electrospun nanofibers have many characteristics such as mimicking extracellular matrix structure, efficiency as bacterial barrier, appropriate water vapor transmission rate, and provision of adequate gaseous exchange which make them ideal candidates for wou...

objective(s): nanoparticles (nps) are known for their specific accumulation in the inflamed tissues of the colon and thus allow a selective delivery to the site of inflammation with minimum adverse effects. the main objective of this work is to attain mesalamine loaded chitosan nanoparticles as a carrier for oral delivery. methods: in this study, mesalamine loaded chitosan nanoparticles were pr...

Thymol, an important and advantageous component of many essential oils, has been applied as an antimicrobial agent in animals. To increase the duration of action of this compound in ruminants, it was decided here to prepare a controlled release carrier for thymol. Hydroxy propyl methyl cellulose (HPMC) and ethyl cellulose (EC) were used as the matrix polymer here. Mixtures of thymol with eight ...
