PM pollution modulates the response of ozone formation to VOC emitted from various sources: Insights from machine learning.

Numerous studies have linked ozone (O) production to its precursors and fine particulate matter (PM), while the complex interaction effects of PM and volatile organic compounds (VOCs) on O remain poorly understood. A systematic approach based on an interpretable machine learning (ML) model was utilized to evaluate the primary driving factors that impact O and to elucidate how changes in PM, VOCs from different sources, NO, and meteorological conditions either promote or inhibit O formation through their individual and synergistic effects in a tropical coastal city, Haikou, from 2019 to 2020. The results suggest that under low PM levels, alongside the linear O-PM relationship observed, O formation is suppressed by PM with higher proportions of traffic-derived aerosol.

Targeting cancer stem cell plasticity in triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is a highly aggressive breast cancer subtype with limited treatment options.

A review on the mechanisms underlying the antitumor effects of natural products by targeting the endoplasmic reticulum stress apoptosis pathway.

Cancer poses a substantial risk to human life and wellbeing as a result of its elevated incidence and fatality rates. Endoplasmic reticulum stress (ERS) is an important pathway that regulates cellular homeostasis. When ERS is under- or overexpressed, it activates the protein kinase R (PKR)-like endoplasmic reticulum kinase (PERK)-, inositol-requiring enzyme 1 (IRE1)- and activating transcription Factor 6 (ATF6)-related apoptotic pathways to induce apoptosis.

[Ozone Pollution Characteristics and Formation Mechanism in a Typical Tropical Seaside City].

To investigate the pollution characteristics and formation mechanism of ambient air ozone(O) in a typical tropical seaside city, we conducted an observational experiment on O and its precursors at an urban site in Haikou, Hainan Province, from June to October 2019. The O pollution characteristics were analyzed comprehensively; the O-NO-VOCs sensitivities and key precursors were determined, and the control strategies for O pollution were carried out. The results were as follows:1 O pollution in Haikou mainly occurred in September and October, with daily maximum 8-h O concentrations in the range of 39-190 μg·m, and the daily variation in O was unimodal, peaking at approximately 14:00.
