Photochemistry and Photobiology, EarlyView.Photodynamic therapy (PDT) is a nonscarring treatment modality that is widely used for skin cancers and early squamous precursor lesions. PDT was previously thought to work primarily by killing cancer cells directly (via apoptosis or necrosis). However, more recent work indicates that a significant mechanism for PDT is the stimulation of anti‐cancer ...

Experimental Physiology, EarlyView.Abstract Despite exercise countermeasures to sustain health and performance in spaceflight, complete maintenance of muscle mass and functions in microgravity is still not possible for most astronauts. The principal cause of the limited effectiveness of existing exercise countermeasures is the difficulty in achieving full loading forces in space.

Clinical Pharmacology &Therapeutics, Volume 119, Issue 4, Page 1057-1069, April 2026.Metformin is the most widely prescribed antidiabetic drug, yet adherence remains difficult to objectively assess. Using untargeted metabolomics and lipidomics, we analyzed plasma from 637 patients with type 2 diabetes (T2D) with confirmed metformin use and 143 nondiabetic controls, annotating 614 metabolites.

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 2, April 2026.ABSTRACT Background Nutritional weight‐loss interventions are known to reduce bone mineral density (BMD), which can be prevented by adding (resistance) exercise training. However, this combined effect is not well studied in non‐obese adults. In addition, the association between biomarkers and metabolite‐based composite health markers with changes in ...

Differential Gene Expression in Human Hippocampus With Aging
Aging Cell, Volume 25, Issue 4, April 2026.2 complementary analysis from a transcriptome study in human hippocampal samples of different ages revealed a set of genes differentially expressed in aged individuals linked to inflammation and immune system pathways, DNA repair (RAD23) or neural activity.

The FASEB Journal, Volume 40, Issue 6, 31 March 2026.ORMDL proteins in the endoplasmic reticulum (ER) negatively regulate serine palmitoyltransferase (SPT) activity in response to the rate of de novo sphingolipid synthesis. Disruption of ceramide homeostasis by myriocin or fumonisin B1 (FB1) appears to destabilize the ORMDL‐SPT complex, leading to ORMDL degradation as a feedback mechanism.

Targeting Cellular Lipid Rafts for Dynamic Nuclear Polarization Nuclear Magnetic Resonance
ChemBioChem, Volume 27, Issue 5, 13 March 2026.Illuminating lipid rafts within intact cells using dynamic nuclear polarization (DNP). Targeting lipid rafts with the protein ostreolysin A allows the selective delivery of DNP‐compatible radicals, generating hyperpolarization of nuclear spins in the lipid raft. Lipid rafts serve as important platforms for membrane and signaling proteins.

Laurdan: Clarifying Photophysics and Advancing the Characterization of Extracellular Vesicles
ChemPhysChem, Volume 27, Issue 5, 13 March 2026.Biophysical properties of extracellular vesicles (EVs) reflect their composition and membrane organization. We introduce a novel approach using time‐resolved emission spectra (TRES) phasor analysis of the polarity‐sensitive probe Laurdan to characterize membranes with complex compositions.

Advanced Healthcare Materials, Volume 15, Issue 10, 13 March 2026.We characterized the distribution of cargo proteins associated with extracellular vesicles using various exogenous loading methods. In all cases, single‐particle analysis revealed that the distribution of protein content per EV is heterogeneous, following an exponential decay function.
