Organic and Inorganic Pollutants, Oxidative Stress Biomarkers, and Electrophoretic Protein Profiles in an Endangered Thresher Shark (Alopias vulpinus) From Southeastern Brazil: A Case Study

Environmental Toxicology, EarlyView.
ABSTRACT A comprehensive screening of different environmental contaminants (total metals, thermostable metal fractions associated with detoxification, and persistent organic pollutants) was conducted in an endangered common thresher shark (Alopias vulpinus ) individual incidentally captured in southeastern Brazil.

A Meta‐Analysis of the Effects of Acute Sleep Deprivation on the Cortical Transcriptome in Rodent Models

Journal of Sleep Research, EarlyView.
How does sleep deprivation affect the brain? We performed a meta‐analysis of publicly available transcriptional profiling datasets characterising the effects of sleep deprivation on cortical gene expression (n = 293 mice, 16,290 genes) and validated our results in an independent sample (n = 222 mice).

Preliminary study of triclosan analysis: A GC/ECD optimization

IOP Conference Series: Earth and Environmental Science
Abstract Triclosan is one of emerging contaminants with antimicrobial and disinfection properties. It is commonly used in soaps, toothpastes, detergents, hand sanitizers, disinfectants, and other personal care products. Triclosan is ubiquitous in environmental samples and its concentration in natural waters is drastically increase owing ...

Solid-Phase Microextraction and GC-ECD of Benzophenones for Detection of Benzodiazepines in Urine [PDF]

Journal of Analytical Toxicology, 1999
Benzodiazepines are common drugs that cause intoxication. Benzodiazepines and their metabolites can be converted by hydrolysis in acid to the corresponding benzophenones, which are easier to be separated from matrices because of their hydrophobic properties.

Atmospheric Deposition of Organic Pollutants: A Comprehensive Review of Sampling and Analytical Methodologies

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Atmospheric deposition of organic pollutants plays a crucial role in the transport and fate of contaminants in the environment, with implications for ecosystem health and human exposure. Persistent organic pollutants (POPs), polycyclic aromatic hydrocarbons (PAHs) and microplastics are increasingly recognized as transboundary threats due to ...

A Novel Multimodal LC–MS/MS Panel for the Comprehensive Diagnosis of Neurometabolic Disorders in CSF

Journal of Inherited Metabolic Disease, Volume 49, Issue 3, May 2026.
ABSTRACT Metabolic testing of cerebrospinal fluid (CSF) is essential for early diagnosis of neurometabolic disorders. However, the large number of differential diagnoses, the phenotypic variance within a clinical picture, and the disease rarity complicate targeted metabolic diagnostics.

Quantifying methane and nitrous oxide emissions from the UK and Ireland using a national-scale monitoring network [PDF]

, 2015
The UK is one of several countries around the world that has enacted legislation to reduce its greenhouse gas emissions. In this study, we present top-down emissions of methane (CH4) and nitrous oxide (N2O) for the UK and Ireland over the period August ...

Phthalates and Mixed Alkyl Phthalates Analysis in Plastics Using GC‐MS With Cold EI

Journal of Mass Spectrometry, Volume 61, Issue 5, May 2026.
ABSTRACT Phthalates are esters of phthalic acid. They are widely used as plasticizers to improve the flexibility, durability, and performance of plastics in a variety of products. However, certain phthalates are associated with significant health risks, including endocrine disruption and reproductive toxicity.
