OBJECTIVE To verify the effect of location and severity of stenosis of the target coronary artery (TCA) on mid-term patency of aorta-anastomosed vs. internal thoracic artery (ITA)-anastomosed radial artery (RA) graft. METHODS During a 3-year period 228 consecutive patients received an RA graft at our institution. In 131 cases the RA was anastomosed to the aorta whereas in 97 the proximal anas...

Introduction: The p19 line of embryonal carcinoma cells develops into neurons, astroglia and fibroblasts after aggregation and exposure to retinoic acid (RA). Dehydroepiandroesteron (DHEA) is a neurosteroid, can increase proliferation of human neural stem cell (NSC) and positively regulated the number of neurons produced. This study was initiated to assess the effect of DHEA on neural progenito...

A new automatic method for preconcentration and separation of radium in water samples has been developed. Such method combines both multisyringe (MSFIA) and multi-pumping (MPFS) flow analysis techniques allowing to analyze larger sample volumes with a higher throughput than other previous methodologies. Ra adsorbed on MnO(2), deposited on cotton fiber, is eluted with hydroxylamine and subsequen...

Background and objectives: Rheumatoid arthritis (RA) is an autoimmune disease with a complex genetic background. The protein tyrosine phosphatase non-receptor type 22 (PTPN22) is a lymphoid specific protein tyrosine phosphatase which is involved in negative regulation of T cell response. Several studies have assessed the association between PTPN22 single nucleotide polymorphisms (SNPs) with RA ...

Background The 2010 rheumatoid arthritis (RA) classification criteria are intended for research purposes and of the disease not diagnostic purposes. It is however a tool which clinicians commonly use in everyday practice when evaluating patients with arthritis. clearly stated that synovitis should be better explained by another disease. However, some who classified as seronegative RA might stil...

The structure of β-molybdenum dichloride is compared with that of TcCl(2) using EXAFS spectroscopy. For TcCl(2), the Tc atom is surrounded by Tc atoms at 2.13(2), 3.45(3), 3.79(4), and 4.02(4) Å. For β-MoCl(2), the Mo is surrounded by Mo atoms at 2.21(2), 2.91(3), and 3.83(4) Å. The latter distances are consistent with the presence of an [Mo(4)Cl(12)] unit in the solid state, one constituted b...

nd in immune-mediated inflammatory diseases, such as rheumatoid arthritis (RA). Paradoxically, this treatment induces sarcoidosis in a small population of RA patients as a class effect. A safer anti-TNF therapeutic strategy requires understanding of the risk factors for sarcoidosis. In Japan, TNF inhibitor was introduced in 2003. We reviewed 226 consecutive patients (65 men and 161 women) who w...
