Metabolomic Effects of CeO₂, SiO₂ and CuO Metal Oxide Nanomaterials on HepG2 Cells [PDF]

open access: yes, 2017
Background: To better assess potential hepatotoxicity of nanomaterials, human liver HepG2 cells were exposed for 3 days to five different CeO2 (either 30 or 100 μg/ml), 3 SiO2 based (30 μg/ml) or 1 CuO (3 μg/ml) nanomaterials with dry primary particle ...

Metabolomic and Single‐Cell Transcriptomic Analyses Shed Light on Secondary Metabolite Profiling and Potential Developmental Dynamics of Glandular Trichomes in Artemisia argyi

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Plant glandular trichomes (GTs) are characterised by their ability to synthesise and store abundant secondary metabolites of significant biological importance. The medicinal plant Artemisia argyi exhibits a dense covering of GTs, yet the precise metabolic compositions and the developmental molecular dynamics of A.

The Preparation of Glucuronic Acid from Gum Acacia [PDF]

open access: yes, 1937
Initial interest in the preparation of glucuronic acid from gum acacia was prompted by several reasons. Being interested in both the chemical and biological fields, the subject of glucuronic acid made a strong appeal.

Distinct Molecular Biomechanical Mechanisms Inhibit Endosperm Cell‐Wall Weakening and Seed Germination at Cold and Warm Nonoptimal Temperatures

open access: yesPlant, Cell &Environment, Volume 48, Issue 11, Page 8047-8067, November 2025.
ABSTRACT Temperature sensing to adjust developmental rates and phenological responses to different climatic environments is critical for plant survival. Population‐based thermal‐time threshold models predict linear relationships between temperature and, for example, seed germination rates (speed), but the mechanisms are not known.

Nicotine Reprograms Aging‐Related Metabolism and Protects Against Motor Decline in Mice

open access: yesAdvanced Science, Volume 12, Issue 40, October 27, 2025.
Long‐term oral nicotine intake protects against age‐related motor decline in mice without eliciting systemic toxicity. Integrated multi‐organ metabolomic profiling and longitudinal gut microbiota analyses reveal that nicotine induces coordinated remodeling of glycolipid and sphingolipid metabolism, enhances NAD⁺ bioavailability, and suppresses ceramide

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.

Homeostasis of Gut Microbiota Protects against Susceptibility to Fungal Pneumonia

open access: yesAdvanced Science, Volume 12, Issue 40, October 27, 2025.
Fungal pneumonia induces inflammation, shown by heightened IL‐6, IL‐1β, TNF‐α levels and a growth in Staphylococcus in the alveolar flora. The gut microbiota, acting through the gut‐lung axis via blood, impacts fungal pneumonia susceptibility by altering lung metabolism and inflammatory responses.

Lactiplantibacillus plantarum OLL2712 Protects From the Intestinal Dysfunction in D‐Galactose Induced Senescent Cells

open access: yesFood Science &Nutrition, Volume 13, Issue 10, October 2025.
Lactiplantibacillus plantarum OLL2712 (OLL2712) on intestinal dysfunction related to cellular senescence was investigated. Using D‐galactose to induce senescence in Caco‐2 cells, OLL2712 suppressed cellular senescence and restored barrier integrity, while microarray analysis revealed it upregulated signaling pathways related to antioxidants and ...
