The incidence of heat-related illnesses and heatstroke continues to rise amidst global warming. Hyperthermia triggers inflammation, coagulation, and progressive multiorgan dysfunction, and, at levels above 40 °C, can even lead to cell death. Blood cells, particularly granulocytes and platelets, are highly sensitive to heat, which promotes proinflammatory and procoagulant changes.

Misfolding of the cellular PrP (PrP) protein causes prion disease, leading to neurodegenerative disorders in numerous mammalian species, including goats. A lack of PrP induces complete resistance to prion disease. The aim of this work was to engineer Alpine goats carrying knockout (KO) alleles of PRNP, the PrP-encoding gene, using CRISPR/Cas9-ribonucleoproteins and single-stranded donor oligonucleotides.

Background: The magnitude of inbreeding depression depends on the recessive burden of the individual, which can be traced back to the hidden (recessive) inbreeding load among ancestors. However, these ancestors carry different alleles at potentially deleterious loci and therefore there is individual variability of this inbreeding load. Estimation of the additive genetic value for inbreeding load is possible using a decomposition of inbreeding in partial inbreeding components due to ancestors.

Background: Mitochondria generate the adenosine triphosphate (ATP) necessary for eukaryotic cells, serving as their primary energy suppliers, and contribute to host defense by producing reactive oxygen species. In many critical illnesses, including sepsis, major trauma, and heatstroke, the vicious cycle between activated coagulation and inflammation results in tissue hypoxia-induced mitochondrial dysfunction, and impaired mitochondrial function contributes to thromboinflammation and cell death.
Methods: A computer-based online search was performed using the PubMed and Web of Science databases for published articles concerning sepsis, trauma, critical illnesses, cell death, mitochondria, inflammation, coagulopathy, and organ dysfunction.

Studies on the mechanisms and regulation of functional assemblies of SNARE proteins mediating membrane fusion essentially make use of recombinant proteins and artificial phospholipid bilayers. We have developed an easy-to-use in vivo system reconstituting membrane fusion in living bacteria. It relies on the formation of caveolin-dependent intracytoplasmic cisternae followed by the controlled synthesis of members of the synaptic SNARE machinery.

Nanoplastics are suspected to pollute every environment on Earth, including very remote areas reached via atmospheric transport. We approached the challenge of measuring environmental nanoplastics by combining high-sensitivity TD-PTR-MS (thermal desorption-proton transfer reaction-mass spectrometry) with trained mountaineers sampling high-altitude glaciers ("citizen science"). Particles < 1 μm were analysed for common polymers (polyethylene, polyethylene terephthalate, polypropylene, polyvinyl chloride, polystyrene and tire wear particles), revealing nanoplastic concentrations ranging 2-80 ng mL at five of 14 sites.

The β1,4-N-acetylgalactosaminyltransferase 2 (B4GALNT2) which synthesizes the histo-blood group antigen Sd is highly expressed by normal colon, but it is dramatically down-regulated in colorectal cancer (CRC). High B4GALNT2 expression in CRC tissues is a marker of longer survival. The molecular bases of B4GALNT2 inhibition in CRC are largely obscure.

The metabotropic glutamate receptors (mGlus) are class C G protein-coupled receptors (GPCR) that form obligate dimers activated by the major excitatory neurotransmitter L-glutamate. The architecture of mGlu receptor comprises an extracellular Venus-Fly Trap domain (VFT) connected to the transmembrane domain (7TM) through a Cysteine-Rich Domain (CRD). The binding of L-glutamate in the VFTs and subsequent conformational change results in the signal being transmitted to the 7TM inducing G protein binding and activation.

In his teaching, Charcot often used artistic representations from previous centuries to illustrate the historical developments of various conditions, particularly hysteria, mainly with the help of his pupil Paul Richer. Charcot liked to draw portraits and sketches of colleagues during boring faculty meetings and students' examinations, including caricatures of himself and others, church sculptures, landscapes, soldiers, and so on. He also used this skill in his clinical and scientific work.

The Société de Pathologie Infectieuse de Langue Française released in 2024 a new national recommendation for clinical practice on the prevention and management of varicella zoster virus (VZV) infection during pregnancy and the perinatal period. The previous recommendation was issued in 1998, at a time of anti-VZV immunoglobulins shortage; it has hence become obsolete. This recommendation is a formalized expert consensus focusing on infectious diseases management; it is drawn up by a multidisciplinary working group (infectiologists, obstetricians, pediatricians, microbiologists, midwives, hygienists).

Soft tissue deficiency around dental implants can negatively impact outcomes in terms of esthetics and long-term stability. While autogenous connective tissue grafting is still considered the gold standard treatment, alternative approaches are being proposed primarily to enhance patient comfort and avoid invasive procedures such as two-sites surgeries using xenogeneic collagen matrices. Despite the advantages, the quality of the regenerated tissues remains unpredictable and, in many cases, questionable, highlighting the need for alternative and innovative approaches.
