STUDY DESIGN Prospective, single-blinded, randomized study. OBJECTIVES To evaluate the efficacy of dilute betadine irrigation of spinal surgical wounds in prevention of postoperative wound infection. SUMMARY AND BACKGROUND Deep wound infection is a serious complication of spinal surgery that can jeopardize patient outcomes and increase costs.(More)
We have previously isolated and identified stem cells from human anterior cruciate ligament (ACL). The purpose of this study was to evaluate the differences in proliferation, differentiation, and extracellular matrix (ECM) formation abilities between bone marrow stem cells (BMSCs) and ACL-derived stem cells (LSCs) from the same donors when cultured with(More)
From January 1993 to September 2002, 931 patients suffered from intertrochanteric fracture and subrochanteric fracture received open reduction and internal fixation with APGN in our institute. Among these patients, 16 patients (1.7%) developed a femoral shaft fracture after the initial fixation with APGN. Removal of the APGN, closed reduction and fixation(More)
BACKGROUND Complex subtrochanteric fractures are uncommon injuries and challenging to manage. We elucidate the role of the Long Gamma AP Locking Nail (LGAPN) in the management of such fractures in the acute stage. METHODS Between 1992 and 2002, 64 consecutive cases with nonpathologic complex subtrochanteric fractures managed with the LGAPN were enrolled(More)
We have previously isolated and identified stem cells from human cruciate ligaments. The goal of this study was to evaluate the proliferation and differentiation abilities of ligament-derived stem cells (LSCs) cultured with growth factors, including fibroblast growth factor 2 (FGF-2), epidermal growth factor, and transforming growth factor-beta 1 (TGF-b1).(More)
Giant cell tumors of the acetabulum are uncommon lesions. Their diagnosis is often delayed due to their slow progression, late onset symptoms and easily been obscured by bowel gas in plain pelvic radiographs. The tumor size is always very large at the time of diagnosis, with major nerve and joint involvement. Management of such tumor remains challenging to(More)
Tissue engineering with stem cells is a fascinating approach for treating anterior cruciate ligament (ACL) injuries. In our previous study, stem cells isolated from the human anterior cruciate ligament were shown to possess extensive proliferation and differentiation capabilities when treated with specific growth factors. However, optimal culture conditions(More)
A 16 Gb/s four-level pulse amplitude modulation (PAM4) underwater wireless optical communication (UWOC) system based on 488-nm laser diode (LD) with light injection and optoelectronic feedback techniques is proposed and successfully demonstrated. Experimental results show that such a 1.8-GHz 488-nm blue light LD with light injection and optoelectronic(More)
A 64 Gb/s four-level pulse amplitude modulation (PAM4) vertical-cavity surface-emitting laser (VCSEL)-based free-space optical (FSO) link with an external light injection scheme is proposed and successfully demonstrated. Experimental results show that the 11.2 GHz VCSEL with an external light injection scheme is sufficiently powerful for 64 Gb/s PAM4 FSO(More)
A 45 Gb/s four-level pulse amplitude modulation (PAM4) transmission based on an 850 nm/7.4 GHz vertical cavity surface emitting laser (VCSEL) with light injection and optoelectronic feedback techniques is proposed. Experimental results show that such an 850 nm/7.4 GHz VCSEL with light injection and optoelectronic feedback techniques is powerful enough for a(More)
