[Viral sensing by RNA helicases].

A key aspect of antiviral immunity is the distinction between "self" and "non-self" components. This distinction can be established through the detection of double-stranded RNA (dsRNA), a common sign of viral infection, by cytosolic RNA helicases. Depending on the organism, two major antiviral pathways can be induced by dsRNA helicases: RNA interference (RNAi) and interferon (IFN) signaling.

Sexually transmitted infections in seafarers: 2020's perspectives based on a literature review from 2000-2020.

Background: Seafarers are a special population. The issue of sexually transmitted diseases among seafarers is as old as navigation itself, and is a public health issue and a matter of concern for seafarers themselves. The purpose of this article is to review the literature on sexually transmitted infections (STIs) in professional seafarers in the 21st century, with a view to guiding maritime physicians in their practice.

Capybara and Brush Cutter Involvement in Q Fever Outbreak in Remote Area of Amazon Rain Forest, French Guiana, 2014.

We investigated a Q fever outbreak that occurred in an isolated area of the Amazon Rain Forest in French Guiana in 2014. Capybara fecal samples were positive for Coxiella burnetii DNA. Being near brush cutters in use was associated with disease development.

Occupational Exposures to Ebola Virus in Ebola Treatment Center, Conakry, Guinea.

We report 77 cases of occupational exposures for 57 healthcare workers at the Ebola Treatment Center in Conakry, Guinea, during the Ebola virus disease outbreak in 2014-2015. Despite the high incidence of 3.5 occupational exposures/healthcare worker/year, only 18% of workers were at high risk for transmission, and no infections occurred.

Ebola Virus-Related Encephalitis.

Ebola patients frequently exhibit behavioral modifications with ideation slowing and aggressiveness, sometimes contrasting with mild severity of Ebola disease. We performed lumbar punctures in 3 patients with this presentation and found Ebola virus in all cerebrospinal fluid samples. This discovery helps to discuss the concept of a specific Ebola virus encephalitis.

Rhabdomyolysis in Ebola Virus Disease. Results of an Observational Study in a Treatment Center in Guinea.

Background: The pathogenesis of Ebola virus disease (EVD) remains unclear. The sporadic nature of Ebola outbreaks and their occurrence in resource-limited settings have precluded the acquisition of extensive clinical and laboratory data. Rhabdomyolysis during EVD has been suggested to occur in previous studies showing increased aspartate aminotransferase-alanine aminotransferase ratios, but, to date, has not been confirmed with creatine kinase (CK) assays.

[Cancer stem cells, cornerstone of radioresistance and perspectives for radiosensitization: glioblastoma as an example].

Cancer stem cells are a subject of increasing interest in oncology. In particular, several data suggest that cancer stem cells are involved in the mechanisms of tumor radioresistance, and may explain the therapeutic failures after radiotherapy. Because of its poor prognosis and high recurrence rate after irradiation, glioblastoma model is often studied in the search for new radiosensitizers.
