A Review of Contamination Status and Health Risk Assessment of Volatile Methylsiloxanes in Environmental Matrices.

Volatile methylsiloxanes (VMS) are a group of synthetic chemical compounds broadly used in industrial applications and consumer products, leading to a sharply increased global emission through diverse pathways. Consequently, human exposure to VMS through inhalation or other routes poses potential health risks. To provide insights for environmental contamination by VMS and its concerning health risks, a systematic literature search was conducted in online databases, including the Web of Science, PubMed, Elsevier ScienceDirect, and the China National Knowledge Infrastructure.

Chlorinated paraffins in plasma of healthy elderly adults: Method development, temporal variability, and exposure determinants.

Chlorinated paraffins (CPs) are a group of persistent organic pollutants widely applied in industrial processes, raising significant concerns regarding human internal exposure through environmental and dietary pathways. Currently, there is a lack of effective and cost-efficient methods for extracting CPs from large-scale human biomonitoring samples, and short-term variations in human internal exposure remain insufficiently characterized, particularly among the vulnerable elderly population. Here a novel, rapid, and highly efficient pretreatment method was developed to simultaneously quantify CPs of varying carbon chain lengths in minimized volumes of human plasma.

[Progress in the metabolic and biotransformation of polycyclic aromatic hydrocarbons and their derivatives in humans].

Polycyclic aromatic hydrocarbons （PAHs） are organic compounds produced primarily through the incomplete combustion of coal， petroleum， and other carbon-based materials. These compounds are environmentally ubiquitous and have attracted widespread attention because they are significantly biologically toxic and have far-reaching implications for public health and societal wellbeing. Consequently， developing a comprehensive understanding of how PAHs and their derivatives metabolically biotransform in the human body is critical for devising precise preventive strategies and targeted health interventions.

Antibiotics in ambient fine particulate matter from two metropolitan cities in China: Characterization, source apportionment, and health risk assessment.

Excessive production and widespread application of antibiotic has led to residues in environmental matrices worldwide. There is limited knowledge of the concentrations of antibiotics bound to ambient fine particulate matter (PM) and their health risks. We investigated the occurrence, sources, environmental driving factors, and health risks of antibiotics in PM samples collected from Beijing and Shijiazhuang, China, during periods of high air pollution.

A critical review of human internal exposure to short-chain chlorinated paraffins and its concerning health risks.

Short-chain chlorinated paraffins (SCCPs) are a complex mixture of chlorinated derivatives of n-alkanes with a chain length of 10-13 carbon atoms. SCCPs have been extensively used in industrial applications, although an alarming concern is increasingly raised in hazarding environmental matrices and biological organisms due to the environmental persistence, bioaccumulation potential, biotoxicity, and long-range atmospheric transport. Herein, this study conducted a critical review of human internal exposure to SCCPs and its concerning health risks by thoroughly analyzing 63 relevant articles screened in online databases, including the Web of Science, PubMed, Elsevier ScienceDirect, and China National Knowledge Infrastructure (CNKI).

Multigenerational effects of disperse blue 79 at environmentally relevant concentrations on zebrafish (Danio rerio) fecundity: An integrated approach.

The brominated azo dye (BAD) Disperse Blue (DB79) is a widespread environmental pollutant. The long-term toxicological effects of DB79 and the mechanisms thereof must be understood to allow assessment of the risks of DB79 pollution. A dual-omics approach employing in silico analysis, bioinformatics, and in vitro bioassays was used to investigate the transgenerational (F-F) toxicity of DB79 in zebrafish at environmentally relevant concentrations and identify molecular initiating events and key events associated with DB79-induced fertility disorders.

Knockdown of Long Noncoding RNA 01124 Inhibits the Malignant Behaviors of Colon Cancer Cells via miR-654-5p/HAX-1.

Background: Previous studies have shown that long noncoding RNAs (lncRNAs) play a key role in cancer, including colon cancer (CC). However, the exact role of long noncoding RNA 01124 (LINC01124) in CC and its mechanisms of action remain unknown. In this study, we investigated the functional effects and the possible mechanism of LINC01124 in CC.

Identification of S23 causing both interspecific hybrid male sterility and environment-conditioned male sterility in rice.

Background: Oryza glumaepatula represents an important resource of genetic diversity that can be used to improve rice production. However, hybrid sterility severely restricts gene flow between Oryza species, and hinders the utilization of distant heterosis in hybrid rice breeding.

Results: In order to fully exploit the beneficial genes of O.
