From position of the uniform concept of the accident medicine the problems of toxicological supply of the ships of MNF are considered. Peculiarities of chemical accidents in the ship conditions are marked. The question about principles of harmful chemical substances regulating, forming air environment of ship living quarters is discussed. The prospects of practical use of antidotal means, intended for protection of personnel from toxic action of carbon dioxide and chemical combinations, causing development of toxic edema of lungs are given.

Toxicologic Pathology Forum: Opinion on Digital Primary Read and Peer Review-Are We There Yet?

Toxicol Pathol

January 2025

Greenfield Pathology Services, Inc., Greenfield, Indiana, USA.

Recent trends in toxicological pathology include implementation of digital platforms that have gained rapid momentum in the field. Are we ready to fully implement this new modality? This opinion piece provides some practical perspectives on digital pathology such as its cost limitations, relative time requirements, and a few technical issues, some of which are encountered for specific lesions, that warrant caution. Although the potential for digital pathology assessment with whole slide images has made great strides, we are of the opinion that it is not yet ready for complete replacement of glass slides in toxicologic pathology safety assessments.

Thyroid tissue is sensitive to the effects of endocrine disrupting substances, and this represents a significant health concern. Histopathological analysis of tissue sections of the rat thyroid gland remains the gold standard for the evaluation for agrochemical effects on the thyroid. However, there is a high degree of variability in the appearance of the rat thyroid gland, and toxicologic pathologists often struggle to decide on and consistently apply a threshold for recording low-grade thyroid follicular hypertrophy.

Investigation into Drug-Induced Liver Damage Using Multimodal Mass Spectrometry Imaging.

J Am Soc Mass Spectrom

January 2025

Maastricht MultiModal Molecular Imaging Institute (M4i), Division of Imaging Mass Spectrometry, Maastricht University, Universiteitssingel 50, 6229 ER Maastricht, The Netherlands.

Drug toxicity during the development of candidate pharmaceuticals is the leading cause of discontinuation in preclinical drug discovery and development. Traditionally, the cause of the toxicity is often determined by histological examination, clinical pathology, and the detection of drugs and/or metabolites by liquid chromatography-mass spectrometry (LC-MS). While these techniques individually provide information on the pathological effects of the drug and the detection of metabolites, they cannot provide specific molecular spatial information without additional experiments.

Glutamine availability may be reduced in chronic diseases, such as type 2 diabetes mellitus (T2DM)-induced by obesity. Herein, the antioxidant, anti-inflammatory and lipid metabolism effects of chronic oral glutamine supplementation in its free and dipeptide form were assessed in ob/ob mice. Adult male C57BL/6J ob/ob mice were supplemented with L-alanyl-L-glutamine (DIP) or free L-glutamine (GLN) in the drinking water for 40 days, whilst C57BL/6J Wild-type lean (WT) and control ob/ob mice (CTRL) received fresh water only.

A sensitive immunoassay for the rapid analysis of fluopicolide.

Talanta

January 2025

Institute of Agrochemistry and Food Technology, Spanish Council for Scientific Research (IATA-CSIC), Av. Agustí Escardino 7, Paterna, 46980, Valencia, Spain. Electronic address:

The analysis of chemical xenobiotics in human, food, and environmental samples has become a global priority. Consequently, both public and private laboratories require rapid, cost-effective analytical methods for quality and safety control. Fluopicolide, a fungicide used to combat plant diseases, poses potential toxicological risks to humans and animals.
