Among 2528 patients operated on using pins, rods, bolts, and screws made of polyglycolic acid or polylactic acid, 108 (4.3%) were affected by a clinically significant local inflammatory, sterile tissue reaction. The three most common indications for the use of these fixation devices were a displaced malleolar fracture, a chevron osteotomy for hallux valgus, and a displaced fracture of the radia...

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...

Transcatheter arterial chemoembolization therapy using polylactic acid microspheres containing aclarubicin hydrochloride (ACR) was performed in 62 patients with primary hepatocellular carcinoma. These microspheres were about 200 microns in diameter and contained 10% (w/w) aclarubicin. A single dose of polylactic acid microspheres containing ACR (50-100 mg of ACR) was administered 1 to 8 times w...

Efforts to expand treatment options for articular cartilage repair have increasingly focused on the implantation of cell polymer constructs. Primary cells cultured from perichondrium, a chondrogenic tissue, were found to survive in vitro within a biodegradable porous polylactic acid matrix. These perichondrocyte-polylactic acid composite grafts were then implanted within osteochondral defects d...

Bone regeneration is a complex, physiological process of bone formation, which can be seen during normal fracture healing, and is involved in continuous remodeling throughout adult life. However, there are complex clinical conditions in which bone regeneration is required in large quantity, such as for skeletal reconstruction of large bone defects created by trauma, infection, tumor resection a...
