    Liver mitochondrial metabolism plays an important role for glucose and lipid homeostasis and its alterations contribute to metabolic disorders, including fatty liver and diabetes. Here Perry et al. develop a method for the measurement of hepatic fluxes by using lactate and glucose tracers in combination with NMR spectroscopy.

    Real-time monitoring of phosphate metabolism and distribution in the live body without ionizing radiation is highly desirable. Here, the authors show dissolution-dynamic nuclear polarization technology can enable nuclear magnetic resonance detection of hyperpolarized 31P of important biological phosphates in aqueous solutions.

    Early detection of gum inflammation caused by dental implants helps prevent tissue damage. Here, the authors present a peptide sensor that generates a bitter taste when cleaved by proteases present in peri-implant disease, embed it in a chewing gum, and compare the probe to existing sensors using patient saliva.

    Preparation of samples for diagnosis can affect the detection of biomarkers and metabolites. Here, the authors use a silver nanoparticle plasmonics approach for the detection of biomarkers in patients as well as investigate the distribution of drugs in serum and cerebral spinal fluid.

    Some cancers with DNA mismatch repair deficiency display microsatellite instability. Here the authors analyse twenty three cancer types at the exome and whole-genome level, and identify loci with recurrent microsatellite instability that could be used to identify patients who would benefit from immunotherapy.

    Whether Alzheimer’s disease originates in basal forebrain or entorhinal cortex remains highly debated. Here the authors use structural magnetic resonance data from a longitudinal sample of participants stratified by cerebrospinal biomarker and clinical diagnosis to show that tissue volume changes appear earlier in the basal forebrain than in the entorhinal cortex.

    NAD+ is an important coenzyme that mediates cellular metabolism and defends against stresses due to age and overnutrition. Here the authors demonstrate unique bioavailability of the NAD+ precursor vitamin nicotinamide riboside (NR) in mice and humans, and show that NR safely elevates human NAD+.

    DNA circulating in the plasma of cancer patients carries features of the primary tumour, however such DNA is found in low levels in brain cancer patients. Here, the authors show that circulating tumour DNA can be detected in the cerebral spinal fluid of cancer patients and that this better recapitulates the primary tumour compared to DNA from the plasma.

    Immune thrombocytopenia (ITP) is caused by autoantibody-mediated platelet clearance, but refractoriness to current immunomodulatory therapies is common. Here the authors show that desialylated platelets can be cleared via hepatic Ashwell–Morell receptor, a process that can be attenuated by sialidase inhibitors, suggesting a new therapy for ITP.
