Human population growth, climate change and economic development are causing major environmental modifications in Western Africa, which will have important repercussions on the epidemiology of sleeping sickness. A new initiative, the Atlas of human African trypanosomiasis (HAT), aims at assembling and geo-referencing all epidemiological data derived from both active screening activities and pas...

Gastric cancer, a leading worldwide cause of cancer mortality, shows high geographic and ethnic variation in incidence rates, which are highest in East Asia. The anatomic locations and clinical behavior also differ by geography, leading to the controversial idea that Eastern and Western forms of the disease are distinct. In view of these differences, we investigated whether gastric cancers from...

Till now only two species of the genus Trichocera, T. annulata and T. hiemalis, were recorded from north Africa. Herewith, we document seven species from Morocco, which extend distribution of the genus and the family to most southern localities of the western Palearctics in Africa (mountain ranges: the Rif, Middle Atlas and Beni Snassen). The following species were found: one new species in the...

Motivation Butterflies represent a model in biology and flagship group for invertebrate conservation. We provide four new resources the Western Palaearctic butterflies: (1) an updated checklist comprising 552 species; (2) curated dataset of 32,126 mitochondrial cytochrome c oxidase subunit I (COI) sequences 532 species, including de novo reference library Maghreb (Morocco, northern Algeria Tuni...

in this paper, we present a new brain tissue segmentation method based on a hybrid hierarchical approach that combines a brain atlas as a priori information and a least-square support vector machine (ls-svm). the method consists of three steps. in the first two steps, the skull is removed and cerebrospinal fluid (csf) is extracted. these two steps are performed using the fast toolbox (fmrib's a...
