Homeostatic Counter‐Regulation Mediates Spermidine‐Induced Triacylglyceride Reduction in Drosophila melanogaster—From Phenotype to Molecular Mechanism

open access: yesThe FASEB Journal, Volume 39, Issue 20, 31 October 2025.
In Drosophila melanogaster females fed a standard diet containing 2.5% yeast extract (low‐yeast diet), spermidine (Spd) administration does not enhance the endogenous Spd pool but increases the excretion of catabolic N1‐acetylspermidine (N1AcSpd) and reduces fat stores. This process requires the catabolic Akh/AkhR pathway.

Are lepton flavor mixings in the democratic mass matrix stable against quantum corrections? [PDF]

open access: yes, 2000
We investigate whether the lepton flavor mixing angles in the so-called democratic type of mass matrix are stable against quantum corrections or not in the minimal supersymmetric standard model with dimension five operator which induces neutrino mass ...

Pleistocene Climate Changes and Lineage Diversification of Sphenarium Grasshoppers (Orthoptera: Pyrgomorphidae)

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We investigate the phylogeographic history and paleodistribution patterns of four closely related grasshopper species of the genus Sphenarium to test the relative impact of Pleistocene climate fluctuations on their diversification. We found that each species responded differently to these fluctuations, but their divergence, distribution, and ...

Length-scale cascade and spread rate of atomizing planar liquid jets

open access: yes, 2018
The primary breakup of a planar liquid jet is explored via direct numerical simulation (DNS) of the incompressible Navier-Stokes equation with level-set and volume-of-fluid interface capturing methods.

Neutrinos in a spherical box

open access: yes, 2003
In the present paper we study some neutrino properties as they may appear in the low energy neutrinos emitted in triton decay with maximum neutrino energy of 18.6 keV.

Skeletal Muscle PGC‐1α Remodels Mitochondrial Phospholipidome but Does Not Alter Energy Efficiency for ATP Synthesis

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 16, Issue 5, October 2025.
ABSTRACT Background The coupling of oxygen consumption to ATP synthesis via oxidative phosphorylation (OXPHOS) is central for cellular energy homeostasis. Some studies suggest exercise training increases the efficiency of ATP synthesis, but the molecular mechanisms are unclear.

Hypoxia‐inducible factor‐2 stabilization is not sufficient to induce erythropoietin production in deeper medullary fibroblasts

open access: yesThe Journal of Physiology, Volume 603, Issue 19, Page 5777-5804, October 1, 2025.
Abstract figure legend Renal erythropoietin (EPO) production was analysed in anaemic and PHD‐inhibitor‐treated wild‐type mice, and mice with genetic fibroblast‐specific hypoxia‐inducible factor (HIF)‐2 stabilization. We found, that PHD inhibition activated HIF‐2 signalling in interstitial fibroblasts of all kidney zones as observed by the induction of ...

Nicotinamide N‐methyltransferase inhibition improves limb function in experimental peripheral artery disease

open access: yesPhysiological Reports, Volume 13, Issue 20, October 2025.
Abstract Peripheral artery disease (PAD) impairs limb perfusion, walking ability, and increases the risk of amputation. Although current therapies reduce cardiovascular events, few interventions improve skeletal muscle function in PAD. Nicotinamide adenine dinucleotide (NAD+) metabolism is disrupted in PAD.

Miniaturized Devices for On‐the‐Spot Generation of Small‐Diameter Vascular Grafts

open access: yesAdvanced Materials Technologies, Volume 10, Issue 17, September 4, 2025.
An intracorporeal extrusion device is developed for on‐the‐spot generation of vascular grafts with tunable diameters spanning from 1 to 6 mm. The device uses biomimetic polymers and light, to promptly obtaining biocompatible and high‐burst pressure‐resistant grafts.
