Prediction of the retentions of polybrominated dibenzo-p-dioxins (PBDDs) by using the retentions of polychlorinated dibenzo-p-dioxins (PCDDs)

open access: yes, 2000
The retention equations ln k' = A + B/T of 49 polychlorinated dibenzo-p-dioxins (PCDDs) and 4 polybrominated dibenzo-p-dioxins (PBDDs) in gas chromatography (GC) have been investigated to evaluate the properties of regression coefficients A and B.

Continuous Alterations in the Gut Microbial Landscape Associated With Suicidal Ideation in First‐Episode Drug‐naïve Major Depressive Disorder

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 6, June 2026.
We define a gut‐microbiota gradient linked to increasing depression severity and suicidal ideation, highlighting severity‐tracking taxa and pathways, particularly Bacteroides stercoris and the bacterial secretion‐system pathway, as potential microbial markers for suicide risk in MDD.

Evaluating the Endocrine‐Disrupting and Oxidative Stress Potential of a 50‐Component Human‐Relevant Complex Chemical Mixture Using In Vitro Tests

open access: yesJournal of Applied Toxicology, Volume 46, Issue 6, Page 2003-2018, June 2026.
ABSTRACT Humans are chronically exposed to mixtures of environmental contaminants. Exposure to endocrine‐disrupting chemicals (EDCs) contributes to increased health impairment observed globally. This study aimed to evaluate the endocrine‐disruptive and oxidative stress potential of a human‐relevant, complex chemical mixture in vitro.

Functional Metagenomics Insights Into the Allium ampeloprasum Rhizosphere Microbiome Under Different Fertilization Regimes

open access: yesMicrobiologyOpen, Volume 15, Issue 3, June 2026.
Shotgun metagenomic sequencing was used to characterize the functional potential of the Allium ampeloprasum rhizosphere microbiome under chemical fertilizer (G1), biofertilizer (G2), and unfertilized (Bulk) soil (G3) management practices. This study revealed that different fertilization regimes altered microbial functional profiles.

Dioxins and polychlorinated biphenyls concentrations in Larus dominicanus. Case study: Marambaia island, Sepetiba bay, Rio de Janeiro State, Brazil - doi: 10.4025/actascibiolsci.v35i3.18344

open access: yesActa Scientiarum: Biological Sciences, 2013
Seabirds play a significant role as bioindicators: they are conspicuous, relatively easy to observe, well-established studied group of organisms, and in the focus of public interest due to pollution in aquatic ecosystem.

Tryptophan Metabolism and Aryl‐Hydrocarbon Receptor Agonists in the Gut Microbiome of People With Myalgic Encephalomyelitis/Chronic Fatigue Syndrome

open access: yesMicrobiologyOpen, Volume 15, Issue 3, June 2026.
The gut microbiome of people with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is investigated to identify changes in microbial tryptophan metabolism. We reveal a subcommunity of microbes that correlates with tryptophan metabolism that differs in structure and diversity and identify differences in stool indoles including aryl‐hydrocarbon
