Mechanosensing in Dendritic Cells

Immunological Reviews, Volume 337, Issue 1, January 2026.
ABSTRACT Since their discovery, dendritic cells have been recognized for their unusual capacity to sense and respond to physical stimuli within their environment. However, it took nearly two decades—and the advent of mechanobiology—to elucidate the underlying mechanisms and functional implications of this mechanical hypersensitivity. In this review, we

Population Genetics of an Endemic Species Mongoloniscus sinensis (Isopoda: Oniscidea) and Diversification Dynamics Across Northern China

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We explored the population genetics and demographic history of an isopod species endemic in temperate China on the basis of three mitochondrial genes. Three clusters were identified. The Midland group has the highest genetic diversity, and the greatest differentiation between the East and West groups was due to the geographical barrier caused by the ...

Proposição de videolaparoscopia em ratos

Acta Cirurgica Brasileira, 1997
Os autores apresentam a possibilidade do uso da videolaparoscopia em ratos. Foram utilizados 10 ratos Wistar. Empregaram um óptica de 3mm, 30 graus, usada em artroscopia. Obtiveram bo visibilização dos órgãos da cavidade peritoneal. A introdução de agulhas especiais e instrumentos delicados permitiram realizar os procedimentos operatórios.
