OBJECTIVES The major problem with repair of an articular cartilage injury is the extensive difference in the structure and function of regenerated, compared with normal cartilage. Our work investigates the feasibility of repairing articular osteochondral defects in the canine knee joint using a composite lamellar scaffold of nano-ß-tricalcium phosphate (ß-TCP)/collagen (col) I and II with bone ...

Colorectal cancer is the fourth most frequently diagnosed cancer and the second leading cause of cancer death. About 96,830 new cases of colon cancer and approximately 40,000 cases of rectal cancer will occur and 50,310 people will die of colon and rectal cancer combined[1]. The long term survival rate of colon cancer patients treated by conventional modalities such as surgery, radiation, and c...

The microbial degradation behavior of poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx) and its compound with several polyesters such as poly(butylene adipate-co-telephtharate) (PBAT), poly(butylene succinate) (PBS), and polylactic acid (PLA) in seawater was tested by a biological oxygen demand (BOD) method. PHBHHx showed excellent biodegradation in seawater in this study. In addition, the...

This study aimed to modify the biological response of cells to ionizing radiation by combination therapy using radio-sensitizer agent and anticancer drug. Super paramagnetic iron oxide nanoparticles (SPIONs) were prepared and used with gemcitabine (Gem). These two agents were encapsulated simultaneously intopoly (D, L-lactic-co-glycolic acid) (PLGA) to form multifunctional drug delivery system....

Bioplastics are frequently utilized in daily life, particularly for food packaging and carrier bags. They can be delivered to biogas plants through a separate collection of the organic fraction municipal waste (OFMSW). The increased demand use bioplastics aimed at mitigating plastic pollution raises significant questions concerning their life cycle compatibility with management units. Anaerobic...

Nanomedicine aims to apply and further develop nanotechnology to solve problems in medicine, related to diagnosis, treatment and/or disease prevention at the cellular and molecular level (Feng, 2006; Feng and Chien, 2003). Nanomedicine by nature is interdisciplinary, with benefits being realised at the interface of science and engineering, physical science and engineering, chemical science and ...

BACKGROUND Star-shaped polymers provide more terminal groups, and are promising for application in drug-delivery systems. METHODS A new series of six-arm star-shaped poly(lactic-co-glycolic acid) (6-s-PLGA) was synthesized by ring-opening polymerization. The structure and properties of the 6-s-PLGA were characterized by carbon-13 nuclear magnetic resonance spectroscopy, infrared spectroscopy,...
