A search for fully reconstructed Λ 0 b baryons was performed, using about 3.5 × 10 6 hadronic Z 0 decays acquired by the DELPHI detector at LEP-1. Two event candidates were found in the colour-suppressed decay channel J/ψΛ 0 , and four in the colour-allowed channels Λ + c π − /a − 1 , with an estimated background of 0.25 and 1.05 events, respectively. 1 Measurements of the Λ 0 b mass yield (561...
We have measured the parity-violating electroweak asymmetry in the elastic scattering of polarized electrons from 4He at an average scattering angle = 5.7 degrees and a four-momentum transfer Q2 = 0.091 GeV2 . From these data, for the first time, the strange electric form factor of the nucleon G(E)s can be isolated. The measured asymmetry of A(PV) = (6.72 +/- 0.84(stat) +/- 0.21(sy...
BACKGROUND Selective cerebral perfusion (SCP) is used for extending the period during which surgical procedures can be safely performed. We sought to determine the direct effects of pH management on cerebral microcirculation and metabolism during SCP. METHODS An experimental SCP porcine model was created by selectively allowing cold perfusate only into the bicarotid brachiocephalic trunk duri...
CIS (cytokine-inducible SH2 protein), SOCS (suppressor of cytokine signaling), or SSI (signal transducers and activators of transcription [STAT]-induced STAT inhibitor) proteins are a family of cytokine-inducible negative regulators of cytokine signaling via Janus kinase (JAK)-STAT pathways. Given the evidence that the JAK-STAT pathway plays a critical role in the cardiovascular system, the pri...
The tumor suppressor p53 regulates apoptosis, cell cycle, and oncogenesis. To explore the roles of p53 in autoimmunity, we studied type 1 diabetes and innate immune responses using C57BL/6 mice deficient in p53. We found that p53-deficient mice were more susceptible to streptozotocin-induced diabetes than control mice, and they produced higher levels of interleukin-1, -6, and -12. The innate im...
Although the JAK/STAT signaling pathway is usually involved in antiviral defense, a recent study suggested that STAT might be annexed by WSSV (white spot syndrome virus) to enhance the expression of a viral immediate early gene in infected shrimps. In the present study, we clone and report the first full-length cDNA sequence for a crustacean STAT from Penaeus monodon. Alignment and comparison w...
Activated monocytes play an important role in the pathogenesis of inflammatory arthritis. Blood monocytes which enter the inflamed joint become activated upon adherence to extracellular matrix and exposure to a complex inflammatory environment. We have analyzed the mechanism of monocyte activation by soluble factors present in inflammatory synovial fluid (SF). Greater than 75% of inflammatory S...
Our previous studies have shown that benzyl isothiocyanate (BITC) suppresses pancreatic tumor growth by inhibiting STAT-3; however, the exact mechanism of tumor growth suppression was not clear. Here we evaluated the effects and mechanism of BITC on pancreatic tumor angiogenesis. Our results reveal that BITC significantly inhibits neovasularization on rat aorta and Chicken-Chorioallantoic membr...
We report on a measurement of the asymmetry in the scattering of transversely polarized electrons off unpolarized protons, A( perpendicular), at two Q2 values of 0.106 and 0.230 (GeV/c)(2) and a scattering angle of 30 degrees <theta(e)<40 degrees . The measured transverse asymmetries are A( perpendicular)(Q(2)=0.106 (GeV/c)(2))=(-8.59+/-0.89(stat)+/-0.75(syst))x10(-6) and A( perpendicular)(Q(2)...
