In rats, oral oleoyl-DHEA is rapidly hydrolysed and converted to DHEA-sulphate [PDF]

open access: yes, 2007
Background: Dehydroepiandrosterone (DHEA) released by adrenal glands may be converted to androgens and estrogens mainly in the gonadal, adipose, mammary, hepatic and nervous tissue.

Shear‐Induced CROSS (Cellular RedOx Spreading Shield) Assembly Sustains Neurotrophic Extracellular Vesicle Production for Functional Neural Networks

open access: yesAdvanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
This article introduces an innovative droplet microfluidic technique for creating drug‐crystal‐loaded microgels that facilitate potent extracellular vesicle production from mesenchymal stromal cells. By mitigating oxidation propagation, these microgels boost neurogenesis and establish functional neuronal connections in microphysiological systems ...

Metarhizium anisopliae Mitigates the Phytotoxicity of Lead and Nanoplastics on Rice by Modifying Physiological, Transcriptomic, Metabolomic Activities, and Soil Microbiome

open access: yesAdvanced Science, Volume 13, Issue 21, 13 April 2026.
Metarhizium anisopliae alleviates the phytotoxic effects of polyethylene nanoplastics (NP) and lead (Pb) in rice by decreasing Pb uptake, restoring antioxidant and hormonal equilibrium, and promoting growth. Additionally, the fungus modifies the rhizosphere microbiota, enhancing both contaminant tolerance and plant growth, thereby effectively ...

Different Transcriptional Responses to Developmental Versus Short‐Term Acclimation Temperatures in Pieris rapae

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Transcriptomic data indicates that gene expression responses underlying developmental thermal plasticity differ from those of short‐term acclimation temperature in the butterfly Pieris rapae. We also identify a small subset of genes for which expression levels depend on the interaction of developmental temperature and short‐term acclimation temperature.

Synthesis of Uridine Diphosphate-Glucuronic Acid

open access: yesChemical and Pharmaceutical Bulletin, 1960
Uridine 5'-phosphoramidate (I) was allowed to react with α-glucuronic acid 1-phosphate (II), and α-uridine diphosphate glucuronic acid (α-UDPGA) (III) was isolated from the reaction mixture by ion exchange chromatography. Likewise, β-UDPGA (V) was produced from (I) and β-glucuronic acid 1-phosphate (IV).

Zinc Treatment Reverses and anti-Zn-Regulated miRs Suppress Esophageal Carcinomas In Vivo [PDF]

open access: yes, 2023
Esophageal squamous cell carcinoma (ESCC) is a deadly disease with few prevention or treatment options. ESCC development in humans and rodents is associated with Zn deficiency (ZD), inflammation, and overexpression of oncogenic microRNAs: miR-31 and miR ...

Gill Adaptation of the Hong Kong Catfish (Clarias fuscus) to Chronic Heat Stress: Tissue Remodeling, Enhanced Antioxidant Defense and Immune Metabolism Regulation

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Continuous high‐temperature culture altered the structure of gill tissue, enhanced antioxidant capacity, and promoted apoptosis C. fuscus. In response, the organism mitigates extensive apoptosis and strengthens its repair capacity by regulating immune and energy metabolism pathways.
