Probiotics are widely used for their health promoting effects, though a lot remain to be discovered, particularly on their mechanisms of action at the molecular level. The functional genomic approach is an appropriate method to decipher how probiotics may influence human cell fate and therefore contribute to their health benefit. In the present work, we focused on Shouchella clausii (formerly named Bacillus then Alkalihalobacillus clausii), a spore-forming bacterium that is commercially available as a probiotic for the prevention and the treatment of intestinal dysbiosis and related gastrointestinal disorders, such as diarrhoea.

Background: Ethnic diversity in cancer clinical trials is essential to ensure that therapeutic advances are equitable and broadly applicable in multicultural societies. Yet, missing consensus on the documentation of ethnic origin, partially based on the complexity of the terminology and fear of discrimination, leads to suboptimal patient management of minority populations. Additionally, eligibility criteria, such as stringent laboratory cut-offs, often fail to account for variations across ethnic groups, potentially excluding patients without evidence-based justification.

Retroviral gene transfer is the preferred method for stable, long-term integration of genetic material into cellular genomes, commonly used to generate chimeric antigen receptor (CAR)-T cells designed to target tumor antigens. However, the efficiency of retroviral gene transfer is often limited by low transduction rates due to low vector titers and electrostatic repulsion between viral particles and cellular membranes. To overcome these limitations, peptide nanofibrils (PNFs) can be applied as transduction enhancers.

In recent decades significant forest expansion into treeless alpine zones has been observed across global mountain ranges, including the Alps, driven by a complex interplay of global warming and land-use changes. The upward shift of treelines has far-reaching implications for ecosystem functioning, biodiversity, and biogeochemical cycles. However, climate variables alone account for only a fraction of treeline dynamics, highlighting substantial research gaps concerning the influence of non-climatic factors.

Managing multiple tasks simultaneously often results in performance decrements due to limited cognitive resources. Task prioritization, requiring effective cognitive control, is a strategy to mitigate these effects and is influenced by the stability-flexibility dilemma. While previous studies have investigated the stability-flexibility dilemma in fully manual multitasking environments, this study explores how cognitive control modes interact with automation reliability.

Curr Opin Neurobiol

January 2025

Animal Physiology, Institute of Neurobiology, University of Tuebingen, Auf der Morgenstelle 28, 72076 Tuebingen, Germany. Electronic address:

Corvids, readily adaptable across social and ecological contexts, successfully inhabit almost the entire world. They are seen as highly intelligent birds, and current research examines their cognitive abilities. Despite being songbirds with a complete 'song system', corvids have historically received less attention in studies of song production, learning, and perception compared to non-corvid songbirds.

Open abdomen treatment (OAT) is associated with significant morbidity and mortality. In cases where primary or delayed fascial closure cannot be achieved, vacuum-assisted wound closure and mesh-mediated fascial traction are indicated, which often result in a planned ventral hernia. If secondary skin closure is not feasible, common treatment of granulated abdominal defects involves split-thickness skin-grafting or healing by secondary intention leading to significant scarring and sometimes mutilating defects.

Nonhuman primate antigenic cartography of SARS-CoV-2.

Cell Rep

January 2025

Center for Virology and Vaccine Research, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA 02215, USA. Electronic address:

Virus neutralization profiles against primary infection sera and corresponding antigenic cartography are integral part of the COVID-19 and influenza vaccine strain selection processes. Human single variant exposure sera have previously defined the antigenic relationships among SARS-CoV-2 variants but are now largely unavailable due to widespread population immunity. Therefore, antigenic characterization of future SARS-CoV-2 variants will require an animal model, analogous to using ferrets for influenza virus.

Assignment of the N-terminal domain of mouse cGAS.

Biomol NMR Assign

January 2025

Department of Chemistry and Chemical Biology, TU Dortmund University, Dortmund, Germany.

Cyclic GMP-AMP synthase (cGAS) is a DNA-sensing enzyme that is a member of the nucleotidyltransferase (NTase) family and functions as a DNA sensor. The protein is comprised of a catalytic NTase core domain and an unstructured hypervariable N-terminal domain (NTD) that was reported to increase protein activity by providing an additional DNA-binding surface. We report nearly complete H, N, and C backbone chemical-shift assignments of mouse cGAS NTD (residues 5-146), obtained with a set of 3D and 4D solution NMR experiments.
