The aim of this study is to investigate the health impact of the introduction of new food resources into the Spanish diet
in the early Modern Age. For this purpose we compare the pathological conditions of teeth from skeletal remains dating from
the Middle (Mediaeval) Ages (11th–15th century) with others of the Modern era (16th–18th century), sampled from historic cemeteries
of north Iberia (Spain). Dental alterations like abscesses, periodontitis, calculus and dental wear, indicate oral hygiene
and habits, and linear enamel hypoplasia (LEH) is considered as an indicator of nutritional status. Significant decreases
of LEH occurred in Modern Age individuals in comparison to Mediaeval values, suggesting the positive influence of increased
diversity of nutritional resources mainly due to intercontinental (America–Europe) trade. 相似文献

Background
Pelodera (Rhabditis) strongyloides is a small saprophytic nematode that lives in decaying organic matter. On rare occasions, it can invade the mammalian skin, causing a pruritic, erythematous, alopecic and crusting dermatitis on skin sites that come into contact with the ground. Diagnosis of the disease is based on case history (a dog living outdoors on damp straw bedding) with characteristic skin lesions and on the demonstration of typical larvae in skin scrapings or biopsy. Pelodera (rhabditic) dermatitis cases have been reported mainly from Central European countries and the United States. 相似文献267.

The volume of human genome sequence and the variety of web-based tools to access it continue to grow at an impressive rate, but a working knowledge of certain key resources can be sufficient to get the most from your genome. This article provides an update to Genome Biology 2000, 1(4):reviews2001.1-2001.5. 相似文献
