Living Low and Dry: Costs of and Resilience to Soil Hydric Stress in a Fossorial Amphisbaenian Reptile

Integrative Zoology, EarlyView.
Soil drought imposes moderate, temporary costs on a strictly fossorial amphisbaenian reptile. However, these animals seem to cope with, at least, moderately short droughts thanks to their peculiar adaptations to living in an underground environment. ABSTRACT The physiological traits of animals can be strongly influenced by climatic fluctuations, and ...

X-ray spectral properties of Seyfert galaxies and the unification scheme

, 2011
Aims: The unification scheme of Seyfert galaxies predicts that the observed differences between type 1 and type 2 Seyfert galaxies are solely due to the differing orientations of the toroidal-shaped obscuring material around AGN.

Survival Remains High in Griffon Vultures 40 Years After Reintroduction

Animal Conservation, EarlyView.
The reintroduction of the Griffon vulture (Gyps fulvus) in French Grands Causses in 1981 is largely regarded as a significant translocation success. 40 years of quality data from intensive monitoring allows us to investigate the survival rates in this long‐lived population on the long term, but also to reflect on the crucial role of adaptive management

The Therapeutic Potential of Farm Dust Extracts in a Mouse Model of Eosinophilic Inflammation

Allergy, EarlyView.
Farm dust extract (FDE) treatment reduces airway eosinophilia, mucus overproduction, and MHC‐II expression on DCs, limiting antigen presentation and Th2 inflammation. It increases PD‐L1 on DCs, promoting T cell deactivation. Additionally, FDE enhances Tregs and upregulates CTLA‐4, reinforcing suppression.

Metabolic thermodynamics: pertinent reference state and energy potentials

The FEBS Journal, EarlyView.
A recommendation and method to view the energy potentials of metabolites with reference to (green arrow) a biochemical precursor state (in green: water, Mg2+, phosphate, bicarbonate, ammonium, and sulfate, at pH = 7) rather than (the red arrow) the physical–chemical reference state (in grayish red) that is alien to biology, that is, O2, H2, N2 at 1 ...

Mycobacterium avium Subsp. paratuberculosis and Human Endogenous Retrovirus in Italian Patients With Inflammatory Bowel Disease (IBD) and Irritable Bowel Syndrome (IBS)

Immunology, EarlyView.
Inflammatory bowel disease (IBD), comprising ulcerative colitis (UC) and Crohn's disease (CD), is a recognised gastrointestinal disorder. Mycobacterium avium subspecies paratuberculosis (MAP) is implicated in IBD pathogenesis. Persistent exposure and active infections by MAP may contribute to the unsilencing of human endogenous retroviruses (HERV ...
