National Cohort Study of Long-Term Exposure to PM Components and Mortality in Medicare American Older Adults.

There is increasing evidence linking long-term fine particulate matter (PM) exposure to negative health effects. However, the relative influence of each component of PM on health risk is poorly understood. In a cohort study in the contiguous United States between 2000 and 2017, we examined the effect of long-term exposure to PM main components and all-cause mortality in older adults who had to be at least 65 years old and enrolled in Medicare.

Four novel Curtobacterium phages isolated from environmental samples.

Intestinal and non-intestinal nasal cavity adenocarcinoma: Impact of wood dust exposure.

Unlabelled: The aim of the present study was to investigate the role of wood dust exposure in intestinal (ITAC) and non-intestinal type (non-ITAC) nasal adenocarcinoma, so as to improve understanding of the oncogenic mechanisms in the light of the recent literature and of evo-devo concepts.

Materials And Methods: All consecutive patients operated in our institution for nasal adenocarcinoma diagnosed on anatomopathology between May 2004 and February 2014 were included. Surgical specimens were examined twice by independent pathologists, blind to wood dust exposure status.

The quest for a nanoparticle-based vaccine inducing broad protection to influenza viruses.

Influenza virus infections are a significant public threat and the best approach to prevent them is through vaccination. Because of the perpetual changes of circulating influenza strains, the efficacy of influenza vaccines rarely exceeds 50%. To improve the protection efficacy, we have designed a novel vaccine formulation that shows a broad range of protection.
