On inter-router point-to-point links, it is useful, for security and other reasons, to use 127-bit IPv6 prefixes. Such a practice parallels the use of 31-bit prefixes in IPv4. This document specifies the motivation for, and usages of, 127-bit IPv6 prefix lengths on inter-router point-to-point links. Information about the current status of this document, any errata, and how to provide feedback o...

OBJECTIVES The human papillomavirus (HPV) immunisation programme in England was introduced in 2008. Monitoring changes in type-specific HPV prevalence allows assessment of the population impact of this vaccination programme. METHODS Residual vulva-vaginal swab specimens were collected from young sexually active women (aged 16-24 years) attending for chlamydia screening across England. Specime...

The anti-inflammatory and cytoprotective tricyclic title compound, C(21)H(18)N(2)O(2), also known as TBE-31, crystallizes with two nearly superimposable mol-ecules in the asymmetric unit. In both mol-ecules, the three ring systems conform to an envelope-chair-planar arrangement. The central ring, in a cyclohexane chair conformation, contains an axial ethynyl group that bends slightly off from a...

A highly specific antigenic protein of 31 kDa from plerocercoid of Spirometra mansoni (sparganum) was obtained by gelatin affinity and Mono Q anion-exchange column chromatography. The purified 31 kDa protein was subjected to N-glycan enzymatic digestion for structural analysis. The relative electrophoretic mobility was analyzed by SDS-PAGE, before and after digestion. On SDS-PAGE after enzymati...
