    Aerobic exercise reverses aging-induced depth-dependent decline in cerebral microcirculation

    Paul Shin, Qi Pian ... Sava Sakadžić
    Cerebral subcortical microcirculation is more vulnerable to aging-induced changes and more responsive to exercise than cortical microcirculation.

    High-resolution quantitative and functional MRI indicate lower myelination of thin and thick stripes in human secondary visual cortex

    Daniel Haenelt, Robert Trampel ... Nikolaus Weiskopf
    In vivo quantitative magnetic resonance imaging at ultra-high magnetic field reveals systematic differences of relaxation parameters (R1) within the human secondary visual cortex at the level of the thin-thick-pale stripes system, which points toward higher cortical myelination of pale stripes.

    Dual control of NAD+ synthesis by purine metabolites in yeast

    Benoît Pinson, Johanna Ceschin ... Bertrand Daignan-Fornier
    Two distinct processes drive coordinated synthesis of purine and pyridine (NAD+) nucleotides in response to AICAR derivatives and ATP.

    Towards a molecular mechanism underlying mitochondrial protein import through the TOM and TIM23 complexes

    Holly C Ford, William J Allen ... Ian Collinson
    Determination of a model of mitochondrial protein import elucidated using a high-resolution transport assay and kinetic modelling.

    Study of efficacy and longevity of immune response to third and fourth doses of COVID-19 vaccines in patients with cancer: A single arm clinical trial

    Astha Thakkar, Kith Pradhan ... Balazs Halmos
    Third dose of COVID-19 vaccine leads to seroconversion in 56% cancer patients that are seronegative after primary vaccination and a fourth can further boost immune response in patients with hematologic malignancies, which can be predicted by IgM and CD19 levels.

    Post-translational flavinylation is associated with diverse extracytosolic redox functionalities throughout bacterial life

    Raphaël Méheust, Shuo Huang ... Samuel H Light
    Bioinformatic and biochemical studies provide evidence that covalently bound flavins are common and participate in wide-ranging extracytosolic redox activities throughout bacterial life.

    A mitofusin-dependent docking ring complex triggers mitochondrial fusion in vitro

    Tobias Brandt, Laetitia Cavellini ... Mickaël M Cohen
    A combination of an in vitro mitochondrial fusion assay with electron cryo-tomography (cryo-ET) reveals distinct steps and protein complexes during mitofusin-dependent fusion between adjacent mitochondrial outer membranes.

    Comprehensive characterization of tumor microenvironment in colorectal cancer via molecular analysis

    Xiangkun Wu, Hong Yan ... Li Liang
    Integrated molecular analysis demonstrated that colorectal cancer can be classified into four molecular subtypes (proliferative, immunomodulatory, immunosuppressed, and immune-excluded subtypes), providing valuable insight into the intricate relationship between tumor microenvironment heterogeneity and various clinical phenotypes.

    Lineage-specific differences and regulatory networks governing human chondrocyte development

    Daniel Richard, Steven Pregizer ... April M Craft
    The transcriptomic and epigenetic landscapes of developing human articular and growth plate cartilage reveal putative gene regulatory networks governing lineage commitment and tissue homeostasis.
