First application of dPCR for Lentiviral Vector Copy Number and Post-infusion monitoring of TCR-Engineered Regulatory T Cells

This study validates a digital PCR (dPCR) assay to demonstrate that TCR-engineered regulatory T cells exhibit superior lentiviral integration and transgene expression compared to conventional T cells, while establishing dPCR as a precise tool for both manufacturing control and long-term in vivo monitoring of these therapies.

Papiliotrema terrestris PT22AV VOCs contribute to soil suppressiveness against soil-borne fungal pathogens

The study demonstrates that the yeast *Papiliotrema terrestris* PT22AV contributes to soil suppressiveness against fungal pathogens by persisting in the rhizosphere and producing antifungal volatile compounds through branched-chain amino acid catabolism via the Ehrlich pathway.

Comparative Effects of 445- and 660-nm Low-Level Laser Irradiation on the Viability and Proliferation of Stem Cells Derived from Human Exfoliated Deciduous Teeth

This study demonstrates that while 445-nm low-level laser irradiation preserves the viability and proliferation of stem cells from human exfoliated deciduous teeth (SHED), 660-nm irradiation significantly reduces these parameters after 72 hours, highlighting the critical importance of wavelength and energy density optimization for regenerative dentistry applications.

Single cell and bulk transcriptomic analyses support patient specific malignant cell state remodeling after neoadjuvant therapy in locally advanced rectal cancer

This study utilizes single-cell and bulk transcriptomic analyses to demonstrate that neoadjuvant therapy in locally advanced rectal cancer primarily induces patient-specific transcriptional state remodeling within malignant cells rather than clonal replacement, with Program2 showing consistent longitudinal reduction post-treatment.

Frequent Hitter Prediction Beyond Classification Models

This study demonstrates that direct regression of empirical Bayes-corrected hit rates and multi-label aggregation strategies outperform traditional threshold-specific binary classification for predicting frequent hitters in high-throughput screening, offering a more robust, cutoff-agnostic approach that improves early enrichment and global ranking.

Epicardial Adipose Tissue in Hyperglucagonemia mice: an experimental model for GLP-1 triple agonists

This study characterizes the anatomical distribution and genetic profile of epicardial adipose tissue (EAT) in hyperglucagonemic αRhebTg mice, establishing them as a novel experimental model for investigating the effects of GLP-1 triple agonists on this metabolically active fat depot relevant to cardiovascular disease.
