Photodynamic Priming and Minocycline Overcome Chemoresistance by Reprogramming the Pancreatic Tumor Immune Microenvironment In Vivo

open access: yesAdvanced Science, EarlyView.
Dual priming with minocycline and photodynamic priming reprograms the pancreatic tumor microenvironment to overcome chemoresistance. By suppressing DNA repair enzyme Tdp1, inducing photooxidative damage, and enhancing irinotecan delivery via light‐activated nanoencapsulation, this strategy remodels the tumor microenvironment and drives immune ...

Wireless, Adaptable and Fully Implantable Battery‐powered Devices for Optical Stimulation of the Spinal Cord in Small Rodents

open access: yesAdvanced Science, EarlyView.
Current technologies for spinal cord optogenetic stimulation rely on external power sources and face reliability constraints in freely behaving animals. Here, a fully implantable, battery‐powered optoelectronic device is introduced, enabling operation in any selected environment with wireless recharging for months‐long stimulation.

A High‐Throughput Live Imaging Platform to Investigate Circuit‐Dependent Regulation of Circadian Rhythms in Brain Tissue

open access: yesAdvanced Science, EarlyView.
Biological rhythms coordinate physiology, from genes to behavior. Study of circadian rhythms in brain tissue is constrained by limited throughput and spatial and temporal information quality. A new platform for high‐throughput, long‐term multiplexed fluorescent live imaging of circadian rhythms in brain slices is introduced.

PANX2 Suppresses Lung Adenocarcinoma Progression by Inducing Disulfidptosis and Enhancing Antitumor Immunity

open access: yesAdvanced Science, EarlyView.
ABSTRACT Lung adenocarcinoma (LUAD) remains a leading cause of cancer mortality with limited therapeutic options. Disulfidptosis, a novel cell death modality driven by disulfide stress, represents a promising target, yet its regulation in LUAD is poorly defined. Here, we identify Pannexin 2 (PANX2) as a tumor suppressor in LUAD.

Fixed point iteration processes for asymptotically nonexpansive mappings

open access: yes, 1994
Let X be a uniformly convex Banach space which satisfies Opial’s condition or has a Fréchet differentiable norm, C a bounded closed convex subset of X, and T : C → C T:C \to C an asymptotically ...

Noninvasive Characterization of Tumor Heterogeneity in HNSCC: From Clinical Utility to Biological Correlates

open access: yesAdvanced Science, EarlyView.
This study establishes a CT‐based radiomics framework to quantify intratumoral heterogeneity (ITH) in HNSCC. Using unsupervised clustering, tumor ROIs and VOIs are analyzed to calculate 2D/3D ITH scores. The score shows strong predictive value for prognosis and immunotherapy response, and is associated with tumor metabolism and immune microenvironment,

Effective Uniform Bounds on the Krasnoselski-Mann Iteration

open access: yes, 2000
This paper is a case study in proof mining applied to non-effective proofsin nonlinear functional analysis. More specifically, we are concerned with thefixed point theory of nonexpansive selfmappings f of convex sets C in normed spaces.

Xenogeneic Mitochondrial Transplantation Improves Selected Age‐Associated Phenotypes in Mice

open access: yesAdvanced Science, EarlyView.
Yak‐derived xenogeneic mitochondrial transplantation improves selected age‐associated phenotypes in mice, enhances mitochondrial functional readouts, and engages host mitochondrial quality‐control pathways. Broad tissue biodistribution, increased ATP production and mtDNA copy number, reduced ROS levels and dysfunctional mitochondria, improved motility ...

Apolipoprotein F is reduced in humans with steatosis and controls plasma triglyceride‐rich lipoprotein metabolism

open access: yesHepatology, EarlyView., 2022
Hepatic APOF transcript levels correlate inversely with plasma TG and hepatic steatosis in humans. ApoF expression in mice promotes VLDL‐TG production and lipoprotein remnant clearance in mice. Abstract Background NAFLD affects nearly 25% of the global population. Cardiovascular disease (CVD) is the most common cause of death among patients with NAFLD,
