Fluid shear stress plays an important role in bone osteogenic differentiation. It is traditionally believed that pulsed and continuous stress load is more favorable for fracture recovery and bone homeostasis. However, according to our clinical practice, we notice that one single stress load is also sufficient to trigger osteogenic differentiation. In the present study, we subject osteoblast MC3...

A load stand has been built and used to det ermine the performance of an open type reciprocating r efrigeration compressor over a range of speeds. The load stand and instrumentation are desc ribed and sample test readings are given. Measured perform ance characteristics for the compressor over a range of speeds are p resented. Aspects of the load stand are discussed and conclusion s are drawn f...

Background: Despite close monitoring of transplant patients, cytomegalovirus (CMV) infection remains one of the most critical problems in the field of transplantation. This study aims to investigate the relationship between CMV viral load and clinical laboratory findings in transplant recipients. Materials And Methods: Thirty-four transplant recipients comprising 15 kidney transplant (KT) reci...

BACKGROUND A study was undertaken to investigate the pathogenesis of pulmonary involvement in human T lymphotropic virus type I (HTLV-I) carriers. METHODS The bronchoalveolar lavage (BAL) cell profile of 30 HTLV-I carriers (15 asymptomatic HTLV-I carriers (AHCs) and 15 symptomatic HTLV-I carriers (SHCs)) with chronic inflammatory diseases of respiratory tract and eight patients with HTLV-I as...

CD4(+) T cells predominate in early lesions in the CNS in the inflammatory disease human lymphotropic T cell virus type I (HTLV-I)-associated myelopathy/tropical spastic paraparesis (HAM/TSP), but the pathogenesis of the disease remains unclear and the HTLV-I-specific CD4(+) T cell response has been little studied. We quantified the IFN-gamma-producing HTLV-I-specific CD4(+) T cells, in patient...

The I/O subsystem is becoming a major bottleneck in an increasing number of computer systems. To provide improved I/O performance, as well as to accommodate growing storage requirements, disk subsystems are increasing in size. A major hurdle to obtaining the performance available from these large disk subsystems is load imbalance, or disk skew. Dynamic data placement, the conventional load bala...

CONTEXT Graduate assistant athletic trainers (GAATs) must balance the demands of clinical care and the academic load of graduate-level students. OBJECTIVE To examine burnout among GAATs with clinical assistantships at National Collegiate Athletic Association (NCAA) Division I institutions and to identify the personal and situational variables that are related to burnout. DESIGN Cross-secti...

OBJECTIVE To examine the cost and cost effectiveness of quarterly CD4 cell count and viral load monitoring among patients taking antiretroviral therapy (ART). DESIGN Cost effectiveness study. SETTING A randomised trial in a home based ART programme in Tororo, Uganda. PARTICIPANTS People with HIV who were members of the AIDS Support Organisation and had CD4 cell counts <250 × 10(6) cells/L...
