Novel scaffolds for vascular tissue engineering were fabricated by co-electrospinning human-like collagen/chitosan and polylactic acid at room temperature and normal pressure. By studying the effects of composition and collecting distance on the morphology of electrospun meshes, we determined that the proper collecting distance and the concentration of the solution are the keys to the success o...

Localization of a ground glass nodule is a difficult challenge for thoracic surgeons, especially for ground glass opacities (GGOs) less than 10 mm in diameter. In this study we implement a new method for preoperative localization of pulmonary (GGOs). From October 2013 to December 2014, computed tomography-guided percutaneous polylactic acid injection localizations were performed for five pulmon...

The possibility to replace damaged or diseased organs with arti®cial tissues engineered from a combination of living cells and biocompatible scaffolds is becoming a reality through multidisciplinary efforts. A number of critical components within this effort are being facilitated by microfabrication and MEMS approaches, including research tools to elucidate mechanisms which control cellular beh...

The Xpert MTB/RIF assay is both sensitive and specific as a diagnostic test. Xpert also reports quantitative output in cycle threshold (CT) values, which may provide a dynamic measure of sputum bacillary burden when used longitudinally. We evaluated the relationship between Xpert CT trajectory and drug exposure during tuberculosis (TB) treatment to assess the potential utility of Xpert CT for t...

objective: in dental treatments, use of carriers for targeted antibiotic delivery would be optimal to efficiently decrease microbial count. in this study, gentamicin was loaded into polylactic co-glycolic acid (plga) microspheres and its release pattern was evaluated for 20 days.   methods: in this experimental study, plga microspheres loaded with gentamycin were produced by the w/o/w method. t...

Objective(s): In this study, drug loaded electrospun nanofibrous mats were prepared and drug release and mechanism from prepared nanofibers were investigated.  Materials and Methods: Paclitaxel (PTX) loaded polylactic acid (PLA) nanofibers were prepared by electrospinning. The effects of process parameters, such as PTX concentration, tip to collector distance, voltage, temperature and flow rate...

In the automotive sector, which is one of sectors where polymers are mostly used, their behaviour and compatibility in secondary processes such as painting coating applications important preference according to usage areas well mechanical thermal properties. this context, it known that surface wettability a polymer material great importance for different application can be stated wetting non-we...

Thiazoles derivatives are consisted in chemical compounds such as antimicrobial and anticancer medicine. Since polylactic-co-glycolic acid (PLGA) polymeric nanoparticles has been conversed about nanomedicine applications and particularly as drug delivery systems. Because of molecular self-assemblies and biodegradability of PLGA polymer, it can be used to carry anti-cancer and antimicrobial drug...
