Background: The objective of the study was the analysis of structure of carcinogenic or mutagenic chemical substances and dusts occurring in Polish enterprises, 2011-2012, including the number of exposed employees reported to the "Central register of data on exposure to carcinogenic or mutagenic chemical substances, mixtures, agents or technological processes", Nofer Institute of Occupational Medicine, Łódź. In the paper the aims, range and methodology of data collecting by the Central Register are presented.
Material And Methods: Qualitative and quantitative analyses of the data on occupational expo- sure to carcinogenic substances and technological processes reported by employers were carried out.
Results: In 2011-2012 approximately 2600 plants reported more than 300 carcinogenic or mutageaic chemical substances annually. The most common occupational chemical carcinogens/mutagens were: benzene, one of the unspecified gasoline, chromium(VI) compounds, asbestos, chroniurn(VI) trioxide, ethylene oxide and benzo[a]pyrene. The highest number of employees was exposed to particular polycyclic aromatic hydrocarbons (PAHs). Hardwood dust was the major occupational carcinogen listed in the technological processes inventory with approximately 11 000 employees exposed in about 650 enterprises annually.
Conclusions: The amended legislation concerning occupational exposure to carcinogens has not significantly influenced the exposure structure n Poland. Nevertheless it permited to determine the actual total number of the occupationally exposed to carcinoLens.

To evade legal controls, new psychoactive substances (NPS), which have been designed as substitutes for traditional and synthetic drugs, are gradually dominating the drug market. Synthetic cannabinoids (SCs), which account for the majority of NPS, are rapidly being derivatized; consequently, controlling increasing abuse by merely listing individual compounds is difficult. Therefore, China has included the entire SC category of SCs listed as legal controlled substances since July 1, 2021.

Chemical modifications are widely used in research fields such as quantitative proteomics and interaction analyses. Chemical-modification targets can be roughly divided into four categories, including those that integrate isotope labels for quantification purposes, probe the structures of proteins through covalent labeling or cross-linking, incorporate labels to improve the ionization or dissociation of characteristic peptides in complex mixtures, and affinity-enrich various poorly abundant protein translational modifications (PTMs). A chemical modification reaction needs to be simple and efficient for use in proteomics analysis, and should be performed without any complicated process for preparing the labeling reagent.

Imidacloprid (IMI) and cadmium (Cd) have been shown to be harmful to mammals separately, but their combined toxicity to mammals remains largely unknown. In this study, biochemical analysis (oxidative stress and serum indicators of liver and kidney function), pathological sections and multiomics (metabolomics and transcriptomics) methods were used to investigate the changes and mechanisms of liver and kidney in mice coexposed to IMI and Cd. Biochemical analysis and pathological section results showed that oxidative stress, organ function, and cell damage were aggravated after the combination of the two methods.

Background: The concept of a Quality marker (Q-marker) has emerged as a crucial tool for ensuring the safety and efficacy of Traditional Chinese Medicine (TCM) formulas. However, significant challenges remained in the identification and practical application of Q-marker, particularly due to the scarcity of reference standards.
Purpose: This study aimed to achieve a multidimensional integration of chemical profiling, target tissue distribution and in vivo high-throughput screening model to effectively identify the Q-marker of Shensong Yangxin Capsule (SSYX) and propose a linear substitution strategy for the quantification of multiple components.

Indocyanine green (ICG) is a water-soluble green substance that is detectable through infrared cameras and emits greenish light. Approved for medical use in the 1950s, ICG has gained prominence as a real-time visualization tool. Widely recognized as a generally safe substance, ICG is applied in diverse fields.
