Persistent effects of a short course of intra-articular dextran sulphate, dextrans, or chondroitin sulphate were examined in rabbit knees. Only dextran sulphate produced gross arthritis, associated with high synovial acid phosphatase and beta-glucuronidase activities. Synovial degradative capacity in synovium-cartilage cocultures was increased 2-fold by dextran sulphate and 1.5-fold by chondroi...

This study is aimed at assessing radiation hazards associated with natural radioactivity in common building materials used Ho Chi Minh City, Vietnam. Thirty-six samples from eighteen types of were collected to measure activity concentrations using the gross alpha/beta counting system and gamma-ray spectrometry. The alpha beta ranged 94.7 ? 31.3 1045.1 112.3 Bqkg-1 104.9 4.7 834.4 37.1 Bqkg-1, r...

BACKGROUND Preclinical studies have shown that norepinephrine can directly stimulate tumor cell migration and that this effect is mediated by the beta-adrenergic receptor. PATIENTS AND METHODS We retrospectively reviewed 722 patients with non-small-cell lung cancer (NSCLC) who received definitive radiotherapy (RT). A Cox proportional hazard model was utilized to determine the association betw...

We discuss the \gravitationally dressed" beta functions in the Gross{ Neveu model interacting with 2d Liouville theory and in SU(N) gauge theory interacting with the conformal sector of 4d quantum gravity. Among the e ects that we suggest may feel the gravitational dressing are the minimum of the e ective potential and the running of the gauge coupling. [email protected] percacci@tsmi19....

Two cases of beta 2 microglobulin amyloidosis following long term haemodialysis found during necropsy are reported. The patients were 59 and 65 year old Japanese men, respectively. In both cases, systemic distribution of beta 2 microglobulin amyloid deposits was observed. The gastrointestinal tract including the stomach, small intestine, and colon showed the distinctive gross feature of rippled...

Although transgenic mice expressing murine B7-1 (mCD80) on their pancreatic beta cells under the rat insulin-1 promoter (RIP-mCD80(+) mice) rarely develop spontaneous beta cell destruction and diabetes, we have previously reported the transgene-dependent induction of profound insulitis and lethal diabetes following multiple low dose injections of the beta cell toxin streptozotocin (MLDS) in RIP...

The transforming growth factor-beta (TGF-beta) family consists of three isoforms and is part of a larger family of cytokines regulating differentiation, development, and tissue repair. Previous work from our laboratory has shown that TGF-beta1 can increase amyloid-beta protein (Abeta) immunoreactive (Abetair) plaque-like deposits in rat brain. The aim of the current study was to evaluate all th...
