Biological materials. recently. are the building blocks of several self-assembling peptide and protein systems.The main challenge In molecular self-assembly is to design molecular building blocks that can undergospontaneous organization. These cyche peptides were produced by an alternating fl'ell number of D- and Laminoacids.which interact through non-covalent interactions co an array of selfas...

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...

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...
