Study evaluates the filtration efficacy of 227 commercially available face masks in Brazil

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

Models for professional use were the most effective at retaining aerosol particles of a size equivalent to the novel coronavirus, followed by TNT masks sold in drugstores. The efficacy of fabric masks ranged from 15% to 70%. A tight fit and lack of seams enhanced protection.

Study finds major anti-inflammatory immune activity that favors oral cancer tumors

MELISA Institute
Peer-Reviewed Publication

This collaborative research made significant progress in the understanding of molecular mechanisms preventing an effective antitumor immune response in oral cancer; the latter due to the production of chemical mediators that induce an anti-inflammatory regulatory response that favors tumor development through a vitamin D signaling pathway. The study was published in Frontiers in Immunology on May 7, 2021.

Conserving and monitoring genetic diversity will benefit nature and society

The Alliance of Bioversity International and the International Center for Tropical Agriculture
Peer-Reviewed Publication

Genetic diversity, which reflects the variation in DNA within species and populations and is the key to their capacity to adapt in times of change, is being lost at an alarming rate. According to an article by 28 authors representing 16 countries, the loss of genetic diversity can affect resiliency in the face of environmental change and result in the loss of important services provided to society.
