Benchmarking gut microbiome indices within and across populations

iMetaOmics, EarlyView.
We compared 10 widely used gut microbiome indices in 12,561 American Gut Project participants and 10 external cohorts, testing how well each distinguished people with healthy lifestyles, responded to 79 environmental factors, and associated with 14 chronic conditions. No single index performed best on all three tasks.

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

Journal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

Low‐Dose Chlorothalonil Induces Testicular Injury Through Disruption of Steroidogenic Signaling in Adult Male Mice

Journal of Applied Toxicology, EarlyView.
ABSTRACT Chlorothalonil (CHL) is a widely used organochlorine fungicide frequently detected in environmental and food matrices. Although increasing evidence indicates adverse effects in nontarget species, the mechanisms underlying CHL‐induced male reproductive toxicity remain incompletely understood.

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Long‐term impact of exposure to Royal Guard, a pyriproxyfen‐based bed net, on pyrethroid‐resistant malaria vectors from Cameroon using DNA‐based metabolic resistance markers

Pest Management Science, Volume 81, Issue 4, Page 2165-2180, April 2025.
We used recently detected P450 DNA‐based markers of pyrethroid resistance in both Anopheles funestus and Anopheles gambiae to demonstrate that although pyrethroid‐resistant mosquitoes have higher ability to survive and live longer after exposure to Royal Guard, this net significantly affects their lifespan, blood feeding ability and interestingly ...
