Mechanical properties are essential considerations for the design of porous scaffolds in the field of tissue engineering. To develop a well-supported hybrid dermal substitute, poly(L-lactide-co-glycolide) (PLGA) yarns were knitted into a mesh with relative fixed loops, followed by incorporation into collagen-chitosan scaffolds (CCS) to obtain PLGA knitted(More)
BACKGROUND To determine how the mechanical property and micro structure affect tissue regeneration and angiogenesis, three types of scaffolds were studied. Acellular dermal matrices (ADM), produced from human skin by removing the epidermis and cells, has been widely used in wound healing because of its high mechanical strength. Collagen scaffolds (CS)(More)
Nanotechnology is a highly promising field, with nanoparticles produced and utilized in a wide range of commercial products. Silver nanoparticles (AgNPs) has been widely used in clothing, electronics, bio-sensing, the food industry, paints, sunscreens, cosmetics and medical devices, all of which increase human exposure and thus the potential risk related to(More)
Full-thickness skin defects represent a significant and urgent clinical problem. Dermal substitutes serving as a regenerative template to induce dermal reconstruction provide a promising method to treat serious skin defects. Although collagen-chitosan dermal scaffolds display good biocompatibility and a suitable porous structure for angiogenesis and tissue(More)
BACKGROUND The emergence of skin substitutes provides a new approach for the treatment of wound repair and healing. The consistent and steady release of angiogenic factors is an important factor in the promotion of angiogenesis in skin substitutes, which usually lack, yet need, a vascular network. METHODS In this study, ginsenoside Rg1, a natural compound(More)
Foot ulceration is one of the most serious complications of diabetes mellitus and may lead to amputation of the lower extremity. Timely prophylaxis and treatment of diabetic foot ulceration are important to maintain a good quality of life. This article reports a complicated diabetic patient with severe limb-threatening necrotizing infection. We successfully(More)
BACKGROUND To investigate the expression and clinical relevance of Src homology region 2 domain-containing phosphatase-1 (SHP-1) and suppressor of cytokine signaling 6 (SOCS6) in acute leukemia (AL). PATIENTS AND METHODS The enrolled AL patients were divided into three groups (newly diagnosed, relapsed, and complete remission [CR]). Healthy donors were(More)
We report a 28-year-old woman who presented with a 6-year history of milk-like discharge from both of her nipples and was diagnosed with prolactinoma based on computed tomography (CT) findings and serum prolactin level. Further breast examination revealed a mass located in the upper outer region of the left breast. She underwent subtotal pituitary tumor(More)
