One-hundred and three Unites States Suffolk sheep were inoculated orally with a scrapie agent preparation and monitored for clinical disease and histopathological lesions characteristic of scrapie. A retrospective study of the polymorphisms at codon 171 of the prion protein (PrP) gene was performed on these sheep. All 63 sheep that developed scrapie during the observation period were homozygous...

Placebo-controlled trials have shown that vitamin C supplementation decreases the duration and severity of common cold infections. However, the magnitude of the benefit has substantially varied, hampering conclusions about the clinical significance of the vitamin. In this paper, 23 studies with regular vitamin C supplementation (>1 g/day) were analyzed to find out factors that may explain some ...

And hence d(x, 0) ≥ lim inf d(0, xn)− lim sup d(xn, x) = 1 Thus x ∈ S. Hence S is closed. Clearly S is bounded since it is contained in B2(0). Define en = (0, 0, . . . , 0, 1, 0, . . . ) be the sequence with all 0’s except a 1 in the nth place. Notice that en ∈ S (for `, `∞, c0). However, notice also that since, in every case, d(en, em) ≥ 1 whenever n 6= m, then the sequence en has no convergen...

A 10-year review (1998 to 2007) of 3188 cases of bacterial meningitis noted that S. pneumoniae accounted for the greatest proportion of cases (58%), followed by group B. streptococcus (18.1%), N. meningitides (13.9%), H. influenzae (6.7%), and L. monocytogenes (3.4%). Among infants less than 3 months of age, group B Streptococcus and gramnegative rods account for most cases of ABM. After 3 mont...
