Periodontitis can damage tooth-supporting bone as stem cells lose their regenerative capacity with age. Researchers at Sichuan University found that IGFBP5 reduced cellular senescence and restored bone-forming ability in dental follicle stem cells by modulating WNT5B-related signaling. An engineered hydrogel carrying IGFBP5-overexpressing cells improved periodontal bone regeneration in rats. The findings highlight a potential strategy for rejuvenating therapeutic stem cells and supporting the development of regenerative treatments for age-related periodontal bone loss.

This news release summarizes a review article in LabMed Discovery proposing a spatiotemporally integrated precision management framework for gastric and colorectal cancers, combining spatial multi-omics, longitudinal ctDNA monitoring, and AI-driven decision support.

A new review in LabMed Discovery examines antibody-oligonucleotide conjugates (AOCs), hybrid molecules that combine the targeting precision of antibodies with the programmability of oligonucleotides. It connects advances in conjugation chemistry with ultrasensitive protein analysis, single-cell and spatial profiling, and targeted delivery of therapeutic oligonucleotides.

A commentary published in LabMed Discovery discusses a CRISPR-assisted nanodroplet platform for rapid, species-level and multiplexed identification of mycobacteria, highlighting how molecular recognition, signal encoding and spatial organization may provide a broader framework for multiplex molecular diagnostics.

Researchers have developed a quasi-solid thermogalvanic gel that uses lignosulfonate derived from papermaking waste as a redox-active component for low-grade heat harvesting. Published in the Journal of Bioresources and Bioproducts, the study combines lignosulfonate, ammonium persulfate, potassium hydroxide and poly(vinyl alcohol) to construct a flexible gel with a Seebeck coefficient of 4.3 mV/K and an output power density of 976 μW/(m²·K²). The material also exploits the photothermal properties of lignin to convert sunlight into a temperature gradient and generate electricity, providing a combined approach to waste valorization and photo-thermo-electric energy conversion.

A research team has mapped genetic variation underlying catechin composition and galloylation across a diverse collection of tea plants. 

Measuring vitamin B₁₂ in food usually means bringing the sample to the laboratory. A new fluorescent sensor could help move part of that process onto something much simpler: a paper strip or cotton swab. A new study published in Biomedical Analysis describes a fluorescence-based strategy for portable vitamin B₁₂ (VB₁₂) detection in food samples. Researchers at Liaocheng University developed boron- and nitrogen-co-doped carbon dots (B, N-CDs) that emit bright blue fluorescence under ultraviolet light but become markedly dimmer when VB₁₂ is present. By transferring this sensing chemistry from a liquid assay onto filter-paper strips and a specially designed cotton-swab sensor, the team created two simple formats intended to make the detection step faster, cheaper, and easier to use outside conventional instrument-heavy workflows.

This meta-analysis of 23 studies compared exercise in the hot (ExH) and exercise in thermoneutral conditions (ExN). ExH produced greater improvements in resting and exercise core temperature, exercise heart rate, sweat rate, and aerobic performance in the heat, but not exercise skin temperature. Benefits of ExH were greater with longer interventions and among elite athletes. Nevertheless, ExN also improved exercise core temperature and heart rate, suggesting that exercise alone can induce modest heat-related adaptations.
