Articular cartilage has limited ability for repair when damaged by trauma or degenerative disease, such as osteoarthritis, which can result in pain and compromised quality of life. Biological surface replacements developed using tissue engineering methods are a promising approach for cartilage repair, which would avoid the need for total joint replacement(More)
Chronic lymphocytic leukemia (CLL) is recognized as a unique lymphoproliferative disorder of CD5(+) B cells. However, many published series of CLL included a subgroup of CD5(-) cases. CD5(-) B cell CLL is a topic of controversy and its nature and true incidence remain unclear. We in this study performed a retrospective analysis of a total of 128 consecutive(More)
The finding of monoclonal B-cell lymphocytosis (MBL) raises questions on the nature of clonal cell expansion and its risk of progression. We identified and characterized 7 cases of clinically benign clonal B-cell lymphocytosis. The clonal lymphocytes were clearly of CD5- and non-chronic lymphocytic leukemia (CLL) phenotype. All cases had mild to moderate(More)
Semiconductor quantum dots (qdots) are emerging as a new class of fluorescent labels. The unique optical properties of qdots make them appealing in laboratory diagnosis; however, qdot-based probes remain to be developed and evaluated for clinical laboratory applications. In this study, 2 different approaches were employed to label hematopoietic cells with(More)
—The world's shipbuilding industry as well as shipping industry is going through some unprecedented recession period in recent years. Shipbuilding companies in China have suffered a lot and many are now focusing on improving their competitiveness to survive the recession. The evaluation of a company's competitiveness is difficult considering the high level(More)
