Baseline tumour vessel perfusion as a non-invasive predictive biomarker for immune checkpoint therapy in non-small-cell lung cancer.

Objective: Current biomarkers for predicting immunotherapy response in non-small-cell lung cancer (NSCLC) are derived from invasive procedures with limited predictive accuracy. Thus, identifying a non-invasive predictive biomarker would improve patient stratification and precision immunotherapy.

Methods And Analysis: In this retrospective multicohort study, the discovery cohort included 205 NSCLC patients screened from ORIENT-11 and an external validation (EV) cohort included 99 real-world NSCLC patients.

Recent Advances of Gaseous Pollutant Catalytic Oxidation over Precious Metal Catalysts with SO Exposure.

Precious metal catalysts are widely used for catalytic oxidation of various gaseous pollutants (CO, methane, and VOCs) due to their excellent catalytic activity. However, they are easily affected by SO and deactivated in actual industrial waste gas or motor vehicle exhaust. Therefore, this review systematically summarizes the representative studies of gaseous pollutant catalytic oxidation over precious metal catalysts with SO exposure.

Rationally manipulating molecular planarity to improve molar absorptivity, NIR-II brightness, and photothermal effect for tumor phototheranostics.

The secondary near-infrared region (NIR-II) fluorescence imaging-guided photothermal therapy (PTT) offers a noninvasive and light-controllable treatment option for deep-seated cancers. However, the development of NIR-II photothermal agents (NIR-II PTAs) that possess the desired properties of high molar absorption coefficient (ε), fluorescence quantum yield (QY), and photothermal conversion efficiency (PCE) remain a challenge due to the contradiction between radiative and nonradiative processes. Herein, we propose a novel side-chain heteroatom substitution engineering strategy to simultaneously enhance ε, QY, and PCE by modifying the molecular planarity.

Neurotransmitters crosstalk and regulation in the reward circuit of subjects with behavioral addiction.

Behavioral addictive disorders (BADs) have become a significant societal challenge over time. The central feature of BADs is the loss of control over engaging in and continuing behaviors, even when facing negative consequences. The neurobiological underpinnings of BADs primarily involve impairments in the reward circuitry, encompassing the ventral tegmental area, nucleus accumbens in the ventral striatum, and prefrontal cortex.
