The recently constructed two dimensional Sen connection is applied in the problem of quasilocal energy-momentum in general relativity. First it is shown that, because of one of the two 2 dimensional Sen–Witten identities, Penrose’s quasi-local charge integral can be expressed as a Nester–Witten integral. Then, to find the appropriate spinor propagation laws to the Nester– Witten integral, all t...

Interactions between normal, protease-sensitive prion protein (PrP-sen or PrP(C)) and its protease-resistant isoform (PrP-res or PrP(Sc)) are critical in transmissible spongiform encephalopathy (TSE) diseases. To investigate the propagation of PrP-res between cells we tested whether PrP-res in scrapie brain microsomes can induce the conversion of PrP-sen to PrP-res if the PrP-sen is bound to un...

AIM To assess academic attainment and special educational needs (SEN) in extremely preterm children in middle childhood. METHODS Of 307 extremely preterm (< or =25 weeks) survivors born in the UK and Ireland in 1995, 219 (71%) were re-assessed at 11 years of age and compared to 153 classmates born at term, using standardised tests of cognitive ability and academic attainment and teacher repor...

The city of Salvador, Bahia, Brazil, has sociodemographic characteristics similar to some African cities. Up to now, it has had the highest prevalence of human T-cell lymphotropic virus type I (HTLV-I) infection (1.74%) in the country. To investigate which strains of HTLV-I are circulating in Salvador, we studied isolates from 82 patients infected with HTLV-I: 19 from the general population, 21...
