Sheep farming was a profitable business for the bishops of Winchester before the Black Death. Evidence from the manor of Crawley demonstrates that investment in the management of the flock peaked in the early fourteenth century. Elsewhere on the estate, improvements in the provision of sires, housing, feeding, medicaments and the labour supply have been shown to impact favourably upon fertility...

The aim of this study was to evaluate the distribution of parasitic intestinal infections in patients attending Padua teaching hospital during a two-year period. Between 1st March 2011 and 28th February 2013, we examined stool specimens from 7341 patients (6127 Italians, 1214 non-Italians) for ova and parasites using microscopy, rapid enzyme immunoassays, culture techniques and molecular method...

This paper is adapted from the text of a seminar of the same title presented as part of the Workshop on Sustainability of Vegetable Breeders’ Genetic Resources, 26 July 1993, at the 90th Annual Meeting of the American Society for Horticultural Science. It represents the distillation of a more extensive treatment of genetic markers and germplasm management (Bretting and Widrlechner, 1995). Disci...

The aim of this contribution is to examine the effect of an indiscriminate epidemic on a population to assess whether or not a catastrophic event can be identified from examination of paleodemographic data. Using paleodemographic techniques, the death assemblage from the Royal Mint site, London, a Black Death cemetery dated 1349 AD, is compared with that from St. Helen-on-the-Walls, York, which...

The ERD2 gene, which encodes the yeast HDEL (His-Asp-Glu-Leu) receptor, is essential for growth (Semenza, J. C., K. G. Hardwick, N. Dean, and H. R. B. Pelham. 1990. Cell. 61:1349-1357; Lewis, M. J., D. J. Sweet, and H. R. B. Pelham. 1990. Cell. 61:1359-1363). SED5, when present in multiple copies, enables cells to grow in the absence of Erd2p. Sequence analysis of SED5 reveals no significant ho...
