A hallmark of chronic and inflammatory diseases is the formation of a fibrotic and stiff extracellular matrix (ECM), typically associated with abnormal, leaky microvascular capillaries. Mechanisms explaining how the microvasculature responds to ECM alterations remain unknown. Here, we used a microphysiological model of capillaries on a chip mimicking the characteristics of healthy or fibrotic collagen to test the hypothesis that perivascular cells mediate the response of vascular capillaries to mechanical and structural changes in the human ECM.

Oral squamous cell carcinoma (OSCC) is the most common manifestation of oral cancer. It has been proposed that periodontal pathogens contribute to OSCC progression, mainly by their virulence factors. However, the main periodontal pathogen and its mechanism to modulate OSCC cells remains not fully understood.

Despite its profound metabolic implications, the molecular alterations underlying this metabolic impairment had not yet been completely elucidated. We performed a comprehensive multi-omics integration analysis, including genomic, epigenomic, and transcriptomic data from fibroblasts derived from a cohort of MSUD patients and unaffected controls to genetically characterize an MSUD case and to unravel the MSUD pathophysiology.

Methodology: The following groups were established: ERI (75/25 wt.% TEGDMA/BISEMA), ERI + 2.

Rural, indigenous populations in Mexico face barriers to accessing sexual and reproductive health (SRH) resources and services. Given the lack of information to inform educational materials tailored to the needs of these indigenous communities, we aimed to: (a) quantitatively characterise the SRH awareness and practices among adolescents and adults in a rural, mostly indigenous community in northern Mexico and (b) qualitatively assess community perspectives on an educational pamphlet with SRH information (e.g.
