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

Conservation 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 ...

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

Semina: 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,

Modificações dos componentes de parede celular do melão tipo Galia durante a maturação

Ciência e Tecnologia de Alimentos, 1997
O presente estudo caracterizou quantitativa e qualitativamente as mudancas nos componentes de parede celular do melao tipo Galia, hibrido Nun 1380, associadas ao processo de maturacao. Os frutos foram avaliados em cinco estadios de maturacao (I-V). O material de parede celular e suas fracoes foram determinados por gravimetria.

Assessment of the application for renewal of authorisation of Biosprint® (Saccharomyces cerevisiae MUCL 39885) for sows

EFSA Journal, Volume 17, Issue 6, June 2019., 2019
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for renewal of authorisation of the product Biosprint® (Saccharomyces cerevisiae MUCL 39885) as a feed additive for sows. S. cerevisiae is considered by EFSA to have qualified presumption of safety (QPS) status.

A parede celular é crucial para a sensibilidade celular ao baixo pH: o papel de peroxidases de classe III e etileno na morte celular em raízes de Arabidopsis thaliana [PDF]

, 2018
Evidence suggests that root cell walls are a target of low pH stress. Severe low pH stress causes cell death in the root tip. The walls of these cells are highly dynamic.

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

Journal 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 ...
