Immunofluorescence revealed double-staining of CHGA and elastase-

Immunofluorescence revealed double-staining of CHGA and elastase-positive neutrophils in the synovium (but not with macrophages, T cells, fibroblasts, B cells, or tyrosine hydroxylase-positive cells). Density of CHGA+ cells was higher in RA synovium compared to OA controls. In OA controls and RA, CHGA levels were similar in plasma and synovial fluid, but levels in synovial tissue superfusate were markedly lower, which indicates that most of the CHGA is of systemic adrenal origin.\n\nConclusion. Increased level of CHGA is a good

marker of systemic sympathetic hyperactivity.”
“Background/Purpose: Revision total hip arthroplasty is technically demanding, especially when treating a large defective femur. The aim of this study was to evaluate the clinical results of cementless total hip arthroplasty revision in patients with advanced femoral bony defects.\n\nMethods:

By using the canaloplasty technique, which osteotomized the https://www.selleckchem.com/products/pci-32765.html proximal femur to reduce the selleck compound width of canal, 12 patients were enrolled and underwent revision operation. Patients were evaluated by radiographic examination and Harris hip score before and after the index procedures.\n\nResults: The average length of follow-up was 38.7 months. All the osteotomies united at a mean of 5.3 months. Structural allografts were used on six patients to augment the thinned cortices. A total of 11 femoral components (91%) achieved and maintained stability at the last Cyclopamine inhibitor follow-up. One patient was complicated with early stem subsidence and another with deep infection. Both patients were treated successfully without late sequelae. The mean Harris hip score improved from 37.2 to 75.0 after the operation (p < 0.05).\n\nConclusion: The canaloplasty technique could be an alternative solution to help revision surgery in some younger patients with advanced femoral

defects.”
“A mathematical model for the dynamics of HIV primary infection is proposed and analysed for the stability of infected state. Further, as there is a time delay for infected CD4(+) T cells to become actively infected, a model is proposed to consider this time delay. The local stability of the delay model is discussed and results are shown numerically. It is found that the delay has no effect on the dynamics of HIV in the proposed model. (C) 2008 Elsevier Ltd.

“Direct contact membrane distillation (DCMD) offers an attractive operation for the separation of mixtures at atmospheric pressure with reasonable energy requirement. A new simultaneous heat and mass transfer model in DCMD in a hollow fiber configuration is presented. Flow regime in feed and permeate side, the variations of mean temperature and concentration along the membrane module, the length of the membrane, and various properties of membrane characteristics are taken into account in the present model.
