Genome‐scale insights into metabolic streamlining and photosynthetic energy balance in the extremophile green alga Picocystis salinarum (Picocystophyceae, Chlorophyta)

Journal of Phycology, EarlyView.
Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...

The Role of Oxidative Stress in Periodontitis

Journal of Periodontal Research, EarlyView.
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

Carotenoid‐Rich Pigment Extract From Micrococcus terreus SK34 Induces Apoptosis in SH‐SY5Y Neuroblastoma Cells: Integrated Metabolomic, Molecular Docking, and Experimental Validation

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Carotenoid extract from Micrococcus terreus SK34 was characterized by LC‐Q‐TOF‐MS and evaluated for its in vitro anticancer potential. The extract exhibited selective cytotoxicity against different cancer cell lines, particularly neuroblastoma cells (SH‐SY5Y), while sparing normal cells.

Extraction of Astaxanthin from Haematococcus pluvialis and Preparation of Astaxanthin Liposomes

Molecules
Astaxanthin has 550 times more antioxidant activity than vitamin E, so it can scavenge free radicals in vivo and improve body immunity. However, the poor stability of astaxanthin becomes a bottleneck problem that limits its application. Herein, Haematococcus pluvialis (H.

Dietary shrimp by‐product meal as a fishmeal replacement: Effects on growth performance and acute stress responses in juvenile Pacific white shrimp (Penaeus vannamei)

Journal of the World Aquaculture Society, Volume 57, Issue 5, October 2026.
Abstract Sustainable aquafeed development requires alternative protein sources that reduce dependence on fishmeal without compromising shrimp performance. This study evaluated shrimp by‐product meal (SBM) as a fishmeal replacer in juvenile Pacific white shrimp (Penaeus vannamei) and assessed their responses to acute air exposure stress.

Natural Compounds Targeting Oncogenic Signaling Networks in Glioblastoma: Molecular Mechanisms, Translational Advances, and Clinical Perspectives

Brain and Behavior, Volume 16, Issue 9, September 2026.
Glioblastoma (GBM) is a highly aggressive brain tumor with a poor prognosis, driven by abnormal signaling pathways that promote growth and resistance to treatment. Conventional therapies are inadequate, highlighting the need for novel multitargeted approaches.

Antioxidant Chemistry of Phenolics in Chinese Herbal Medicines: A Holism‐Based Review

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Phenolic antioxidants in CHMs mainly include chalcone, stilbene, flavonoid, xanthone, and Diels–Alder‐type adducts. They undergo direct and indirect pathways to exert antioxidant action. The indirect pathway is transition metal‐chelating, while the direct pathway comprises several redox‐based reactions (e.g., SET and HAT) and RAF reactions.
