Bioimaging of sense organs and the central nervous system in extant fishes and reptiles in situ: A review

open access: yesThe Anatomical Record, EarlyView.
Bioimaging of the sense organs and brain of fishes and reptiles. Left panel: 3D reconstruction of the head and brain of the deep‐sea viperfish Chauliodus sloani following diceCT. Right panel: A 3D reconstruction of a 70‐day‐old embryo head of the bearded dragon Pogona vitticeps following diceCT, showing the position of the segmented brain within the ...

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

open access: yesThe Anatomical Record, EarlyView.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.

TRIB3 suppresses milk fatty acids metabolism by inhibiting p‐AKT/PPARG signaling in goat mammary epithelial cells

open access: yesAnimal Research and One Health, EarlyView.
In this study, it revealed that TRIB3 could mediate the transcriptional activity of PPARG, inhibit the phosphorylation of akt, and reduce the expression of lipid metabolism‐related genes, thus inhibiting TAG synthesis and affecting fatty acid composition.

Analysis of triacylglycerol and phospholipid sn‐positional isomers by liquid chromatographic and mass spectrometric methodologies

open access: yesMass Spectrometry Reviews, EarlyView., 2023
Abstract Analysis of triacylglycerol (TG) and phospholipid sn‐positional isomers can be divided into two main categories: (a) direct separation by chromatography or other means such as ion mobility mass spectrometry and (b) quantification of regioisomer ratios by structurally informative fragment ions with mass spectrometric methods.

Approaches to repurposing reverse transcriptase antivirals in cancer

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
This review highlights the role of reverse transcriptase (RT) inhibition in cellular regulation associated with non‐terminal repeat retrotransposons and endogenous retroviruses. Based on their pleiotropic characteristics, RT inhibitors (RTIs) are discussed as potential anticancer agents.

Reduced Adult Neurogenesis in Humans Results From a Tradeoff Rather Than Direct Negative Selection

open access: yesBioEssays, EarlyView.
Embryonic radial glia (RG) generate neurons, glial cells, and later adult neural stem cells, which sustain adult neurogenesis (top, left to right). Human‐specific genetic modifications (blue arrow), selected to boost early RG neurogenic activity, may lead to premature RG exhaustion and reduced adult neurogenesis in the human brain (bottom).

Ethnomedicinal Uses, Phytochemistry, Pharmacological Activities, and Toxicology of the Subfamily Gomphrenoideae (Amaranthaceae): A Comprehensive Review

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT The subfamily Gomphrenoideae is composed of about 480 accepted species, many of which have been historically used as medicinal plants, reason why they have been studied in terms of chemical profile, biological activity, and safety. This review consolidates the advances in research on this subfamily over the past 47 years, emphasizing its ...
