We investigated unusual crow mortality in Bangladesh during January-February 2011 at two sites. Crows of two species, Corvus splendens and C. macrorhynchos, were found sick and dead during the outbreaks. In selected crow roosts, morbidity was ~1 % and mortality was ~4 % during the investigation. Highly pathogenic avian influenza virus H5N1 clade 2.3.2.1 was(More)
In this study, we purified an acidic β-galactosidase to homogeneity from Ginkgo biloba seeds (β-Gal'ase Gb-1) with approximately 270-fold purification. A molecular mass of the purified β-Gal'ase Gb-1 was estimated about 35 kDa by gel filtration and 32 kDa by SDS-PAGE under non-reducing condition, respectively. On the other hand, β-Gal'ase Gb-1 produced a(More)
Rice α-fucosidase (α-fucosidase Os, 58 kDa) that is active for α1-4 fucosyl linkage in Lewis a unit of plant N-glycans was purified to homogeneity. α-fucosidase Os showed activity against α1-3 fucosyl linkage in Lacto-N-fucopentaose III but not α1-3 fucosyl linkage in the core of plant N-glycans. The N-terminal sequence of α-fucosidase Os was identified as(More)
BACKGROUND Shorter childhood telomere length (TL) and more rapid TL attrition are widely regarded as manifestations of stress. However, the potential effects of health interventions on child TL are unknown. We hypothesized that a water, sanitation, handwashing (WSH), and nutritional intervention would slow TL attrition during the first two years of life. (More)
