background: stroke, one of the most important causes of morbidity and mortality in the world, is of great importance in young adults (15-45 years), amongst whom the causes of stroke and transient ischemic attack (tia) are different from those in older ages and a significant portion of them have no known etiology. patent foramen ovale (pfo) is considered a probable cause in this group. methods: ...

Malaria remains the most dangerous tropical disease for the French troops deployed overseas. In 2003, 768 cases in the French army were declared along with an increase of incidence of 400% in comparison with 2002, mainly due to the Licorne peacekeeping operation in Ivory Coast. In order to ensure fast diagnosis in the field, a rapid immunochromatographic test (NOW malaria test; Binax, Portland,...

Background and Purpose: The prevalence of a patent foramen ovale has been shown to be increased in patients with ischemic stroke. Transesophageal echocardiography, transthoracic echocardiography, and transcranial Doppler examination with contrast injection can all be used to search for a patent foramen ovale. We compared the accuracy of these techniques for identifying a patent foramen ovale in...

Effect of topical sunscreens on the UV-radiation-induced suppression of the alloactivating capacity in human skin in vivo. A 83 year old woman was transferred from the departnent of surgery because of a syncopal attack with hypotension. Twenty days before she had ha...

Humans are infected by four recognized species of malaria parasites. The last of these to be recognized and described is Plasmodium ovale. Like the other malaria parasites of primates, this parasite is only transmitted via the bites of infected Anopheles mosquitoes. The prepatent period in the human ranges from 12 to 20 days. Some forms in the liver have delayed development, and relapse may occ...

The fixation of neutral compensatory mutations in a population depends on the effective population size of the species, which can fluctuate dramatically within a few generations, the mutation rate, and the selection intensity associated with the individual mutations. We observe compensatory mutations and intermediate states in populations of the malaria parasite Plasmodium ovale. The appearance...
