Beta-glucana from Saccharomyces cerevisiae: constitution, bioactivity and obtaining /
Beta-glucana de Saccharomyces cerevisiae: constituição, bioatividade e obtenção

open access: yesSemina: Ciências Agrárias, 2008
b-glucans are polysaccharides that constitute the structure of the cell wall of yeast, fungi and some cereals, which differs each other by the linkages between glucose units. An important source of these polymers is the Saccharomyces cerevisiae cell wall,

Multiple global‐change drivers and cascading effects in Mediterranean ecosystems: Lessons from an iconic national park

open access: yesConservation Science and Practice, Volume 8, Issue 6, June 2026.
Mediterranean ecosystems face complex, multi‐trophic impacts from global‐change drivers, yet responses are often studied in isolation. Using the Doñana Protected Area as a case study, we illustrate how anthropogenic pressures on key species like cork oaks and rabbits, as well as increases in species like wild boar and invasive crayfish, lead to ...

Ethanol Alters DNMT1/3a/3b Expression Profile, Promotes Persistent DNA Hypomethylation in Human Brain Endothelial Cells and Impairs Late Cortical Angiogenesis

open access: yesJournal of Neurochemistry, Volume 170, Issue 2, February 2026.
Ethanol exposure alters brain endothelial cell function and blood–brain barrier integrity. In human brain microcapillary endothelial cells (HBMEC) and mouse brain endothelial cells (MBEC) from a prenatal alcohol exposure (PAE) model, ethanol increased DNA methyltransferas‐1 (DNMT1) activity and reduced DNA methylation, affecting DNMT3a/3b, methyl‐CpG ...

Role of CD8 Regulatory T Cells versus Tc1 and Tc17 Cells in the Development of Human Graft‐versus‐Host Disease

open access: yesJournal of Immunology Research, Volume 2017, Issue 1, 2017., 2017
CD8+ T cells that secrete proinflammatory cytokines play a central role in exacerbation of inflammation; however, a new subpopulation of CD8 regulatory T cells has recently been characterized. This study analyzes the prominent role of these different subpopulations in the development of graft‐versus‐host disease (GVHD).
