    Addressing shortfalls of laboratory HbA1c using a model that incorporates red cell lifespan

    Yongjin Xu, Richard M Bergenstal ... Ramzi A Ajjan
    The person-specific adjusted HbA1c addresses non-glycaemic variation in laboratory HbA1c due to red blood cell lifespan differences, potentially providing a better marker to predict diabetes complications and guide glycaemic management.

    Single-cell dynamics of pannexin-1-facilitated programmed ATP loss during apoptosis

    Hiromi Imamura, Shuichiro Sakamoto ... Akira Kakizuka
    Cleavage of pannexin-1 channel by caspases facilitates the loss of intracellular ATP level and attenuates glycolytic metabolism of apoptotic cells.

    An open label randomized controlled trial of tamoxifen combined with amphotericin B and fluconazole for cryptococcal meningitis

    Nguyen Thi Thuy Ngan, Nhat Thanh Hoang Le ... Jeremy N Day
    Despite evidence of significant anti-cryptococcal activity in vitro and animal models, including synergy with other antifungal agents, high-dose tamoxifen has no impact on cerebrospinal fluid sterilization in cryptococcal meningitis.

    Continuous sensing of nutrients and growth factors by the mTORC1-TFEB axis

    Breanne Sparta, Nont Kosaisawe ... John G Albeck
    Single-cell data on cell signaling responses to nutrient variation enable quantitative models of cellular control over protein synthesis, formalizing the concept of mTOR as a homeostatic controller of cellular metabolism.

    Drosophila TRPγ is required in neuroendocrine cells for post-ingestive food selection

    Subash Dhakal, Qiuting Ren ... Youngseok Lee
    Genetic, behavioral, and biochemical evidence reveals that the Drosophila TRPγ channel is required in neuroendocrine cells for the starvation-induced switch in preference to less palatable but more nutritive food.

    Hypermetabolism in mice carrying a near-complete human chromosome 21

    Dylan C Sarver, Cheng Xu ... G William Wong
    Mice carrying a near-complete human chromosome 21 are hypermetabolic and have increased thermogenesis due to sarcolipin overexpression in the skeletal muscle, leading to persistent uncoupling of the sarco(endo)plasmic reticulum Ca2+ ATPase pump activity and heat generation.

    Monitoring single-cell dynamics of entry into quiescence during an unperturbed life cycle

    Basile Jacquel, Théo Aspert ... Gilles Charvin
    A switch-like cell fate divergence revealed by continuous single-cell tracking during entry into quiescence.

    Nuclear magnetic resonance-based metabolomics with machine learning for predicting progression from prediabetes to diabetes

    Jiang Li, Yuefeng Yu ... Bin Wang
    Lipoprotein particle size and composition, fatty acids, and amino acids were associated with the risk of incident diabetes, and adding the selected metabolites could significantly improve the risk prediction of progression from prediabetes to diabetes beyond the conventional clinical variables.

    Age-dependent electroencephalogram (EEG) patterns during sevoflurane general anesthesia in infants

    Laura Cornelissen, Seong-Eun Kim ... Charles B Berde
    Alpha EEG oscillations emerge at 4 months of age during sevoflurane general anesthesia, and unlike in adults, have a widespread spatial distribution that likely reflects differences in brain development.

    High fat diet induces microbiota-dependent silencing of enteroendocrine cells

    Lihua Ye, Olaf Mueller ... John F Rawls
    Enteroendocrine cells sense nutrients in the gut and regulate digestive physiology but are rendered insensitive following fat ingestion due to alteration of gut microbiota.
