Metrics of cardiovascular health, such as vascular resistance and cardiac output, can be monitored via synchronized sensors for electrocardiography and multispectral photoplethysmography that are placed on the chest and peripherally.
Disrupting the CD47–SIRPα checkpoint in tumour macrophages and delivering a tumour-opsonizing monoclonal antibody maximizes the macrophages’ cooperative phagocytic potency.
Fusing the anti-inflammatory enzyme indoleamine 2,3-dioxygenase to the tissue-anchoring protein galectin-3 ameliorates inflammation at the injection site while avoiding systemic immune suppression, as shown in multiple rodent models of inflammation.
The algorithmic detection of cancer-associated variants can be accelerated by leveraging machine-learning classifiers to filter out reads matched to pan-genome k-mer sets.
Amphiphilic peptides can aid the delivery of CRISPR ribonucleoproteins into primary human lymphocytes at low toxicity, boosting editing yields with respect to the use of electroporation.
Confining the Zika virus within a self-adjuvanting hydrogel that forms a subcutaneous inflammatory niche stimulates strong immune responses in mice without inducing infection.
Antitumour responses mediated by T helper 17 cells can be induced by intratumourally injected hollow nanoparticles displaying the polysaccharide mannan.
Each of the 13 protein-coding genes in the mouse mitochondrial genome can be ablated using a library of optimized double-stranded-DNA deaminase-derived cytosine base editors.
The targeted delivery of the short-chain fatty acid butyrate to the lower gastrointestinal tract by polymeric nanoscale micelles restores intestinal homeostasis in mouse models of peanut allergy and colitis.
Liposomal nanoparticles incorporating photosensitive lipids and enclosing paramagnetic molecules enable the mapping, via magnetic resonance imaging, of spatial variations of light intensity in illuminated brain tissue in living animals.
Pooled testing for the diagnosis of COVID-19 via isothermal nucleic acid amplification and detection can be automated by using electromagnetically actuated swarms of millimetric magnets to handle droplets of magnetized samples on a microfluidic chip.
Water exchange through the transmembrane channel aquaporin-4 can be measured by conventional dynamic-contrast-enhanced magnetic resonance imaging and is a sensitive biomarker of the proliferation of gliomas and their resistance to chemotherapy.
Cytokine receptor agonists can be designed with longer half-lives in circulation and with enhanced penetration of the blood–brain barrier by genetically grafting macrocyclic peptides into the structural loops of fragment crystallizable regions.
Off-the-shelf microphones and earbud components connected to a smartphone can be as effective as an expensive clinical-grade device at measuring otoacoustic emissions to screen for hearing loss.
The flux of autophagosomes in heart tissue can be detected in live mice via the fluorescence and magnetic resonance properties of intravenously injected iron oxide nanoparticles decorated with fluorescent peptides cleavable by lysosomal cathepsins.
