beta(2)-Microglobulin (beta2-m) is a major component of dialysis-related amyloid fibrils. Although recombinant beta2-m forms needle-like fibrils by in vitro extension reaction at pH 2.5, reduced beta2-m, in which the intrachain disulfide bond is reduced, cannot form typical fibrils. Instead, thinner and flexible filaments are formed, as shown by atomic(More)

BACKGROUND Recent study has demonstrated that beta-lactamase inhibitors including clavulanate, sulbactam and tazobactam have an vitro antibacterial effect on Helicobacter pylori. Here we describe the relationship between viability and cell profiles of H. pylori exposed to beta-lactamase inhibitors and some antibiotics in a short-time course. MATERIALS AND(More)

The effects of the dietary oligosaccharide raffinose on immune responses, with special reference to its anti-allergic functions, were examined in vivo. First, feeding a diet supplemented with 50 g raffinose/kg to BALB/c mice significantly (P<0.05) increased interleukin (IL) 12 secretion from isolated Peyer's patch (PP) cells in vitro compared with feeding(More)
