A Versatile Engineering Platform for the Fabrication of Prosthetic Venous Valves Using Electrospinning

Advanced Healthcare Materials, Volume 15, Issue 16, 24 April 2026.
Percutaneous prosthetic venous valves are fabricated by embedding stents in an electrospun matrix that extends luminally to form leaflets. The design shields leaflets from hyperplastic cells, isolates struts from blood contact, and avoids discrete anchoring points.

Terapia celular cardíaca com células mesenquimatosas

Revista Portuguesa de Cardiologia, 2013
Resumo: A doença cardiovascular é uma das principais causas de mortalidade e morbilidade em todo o mundo e, apesar de os avanços na terapêutica médica e intervenção percutânea, o prognóstico de doenças como a cardiopatia isquémica e o pós-enfarte do miocárdio continuam a ser consideravelmente inferiores ao desejado.

Enzymatic Poly(gallic acid)‐grafted L‐Histidine Reduces Cell Inflammation and Oxidative Stress: In Silico and In Vitro Studies

Chemistry &Biodiversity, Volume 23, Issue 4, April 2026.
Microwave‐assisted grafting yields a PGAL–His conjugate with enhanced binding through electrostatic and hydrogen‐bond interactions. The material modulates THP‐1 macrophage response, reducing ROS production, pro‐inflammatory cytokines (IL‐6, IL‐1β, TNF‐α), and cell adhesion.

T cell receptor signaling pathway is overexpressed in CD4+ T cells from HAM/TSP individuals

Brazilian Journal of Infectious Diseases, 2015
Human T-lymphotropic virus type 1 (HTLV-1) is a human retrovirus related to the chronic neuroinflammatory disease HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). CD4+ T cells activation appears to play a key role on HTLV-1 infection.
