Adaptive Cellular Responsiveness to Electrical Stimulation at the Skin‐Electrode Interface

Advanced Science, EarlyView.
This study presents an adaptive bioelectronic response in which sustained electrical stimulation (ES) upregulates voltage‐gated calcium channels (VGCCs) and enhances cellular sensitivity to subsequent ES at the skin‐device interface. VGCC‐associated adaptive sensitization promotes regenerative wound‐healing responses in vivo, including accelerated ...

Comparison of confidence intervals for fraction in finite populations

Quantitative Methods in Economics, 2011
Consider a finite population. Let θ ∈(0,1) denotes the fraction of units with a given property. The problem is in interval estimation of θ on the basis of a sample drawn due to the simple random sampling without replacement. In the paper three confidence

PHGDH‐Mediated Serine Metabolism in Nucleus Pulposus Cells Is a Potential Therapeutic Target for Intervertebral Disc Degeneration

Advanced Science, EarlyView.
When nucleus pulposus cells senesce, PHGDH decreases, reducing serine synthesis and glutathione, impairing antioxidant capacity. The intermediate α‐KG also drops, lowering JMJD3 demethylase activity, increasing H3K27me3 at the Rap1b promoter, and reducing Rap1b expression, whose down‐regulation in turn activates mTORC1 and suppresses autophagy ...

A CT Lesion Foundation Model for Non‐Invasive Assessment of Hepatocellular Carcinoma Aggressiveness and Prediction of Recurrence Risk

Advanced Science, EarlyView.
A computed tomography lesion foundation model, built by sequential self‐supervised pretraining on generic and hepatocellular carcinoma‐specific lesion images, non‐invasively assesses microvascular invasion and pathological grade from contrast‐enhanced CT and stratifies postoperative recurrence risk.

Bivariate generalization of the Gauss hypergeometric distribution

, 2014
: The bivariate generalization of the Gauss hypergeometric distribution is defined by the probability density function proportional to x α1−1y α2−1 (1 − x − y) β−1 (1 + ξ1x + ξ2y) −γ , x > 0, y > 0, x + y 0, i = 1, 2, β > 0, −∞ −1, i = 1, 2 are ...

18F‐FGln PET/CT Imaging of Glutamine Uptake Has Potential for Predicting Immunotherapy Response in Hepatocellular Carcinoma

Advanced Science, EarlyView.
18F‐FGln PET/CT imaging serves as a marker of Gln uptake in hepatocellular carcinoma. Tumors with high Gln uptake drive Treg‐mediated immunosuppression and immune evasion during antitumor immunotherapy. Conversely, tumors with low Gln uptake maintain sufficient Gln in the TME, suppressing Tregs and enabling cytotoxic T cells to inhibit tumor growth ...
