Changes in Plasma Sphingolipid Metabolites Following Roux‐En‐Y Gastric Bypass in Women With Obesity and Type 2 Diabetes: A Pilot Metabolomic Cohort Study

Lipids, EarlyView.
ABSTRACT Although sphingolipids are key players in lipotoxicity and metabolic diseases, their response to bariatric surgery and their relation to metabolic improvement remain unclear. This pilot study investigated plasma sphingolipid remodeling after Roux‐en‐Y gastric bypass (RYGB) and its associations with clinical and biochemical markers of ...

Simulating climate change scenarios established by the Intergovernmental Panel on Climate Change in aquatic mesocosms

Limnology and Oceanography: Methods, EarlyView.
Abstract Climate change poses a major threat to ecosystems worldwide, with temperature changes being a key driver of ecological disruption in aquatic environments due to the limited ability of many aquatic species to relocate in response. Despite advances in aquatic experimental approaches to temperature control, most studies rely on simplified warming

Tailoring SHG Efficiency via t‐Te Nanocrystals in Tellurite Glasses by Femtosecond Laser Micromachining

Laser &Photonics Reviews, EarlyView.
Femtosecond laser irradiation at the glass surface induces symmetry breaking and crystallization of triclínic t‐Te nanophases, enabling intense second‐harmonic generation (SHG). The illustration depicts the fs‐pulse interaction, structural rearrangement, and nonlinear activation from amorphous tellurite glass to crystalline regions.

Study of Solvent Effect on PVDF‐HFP Gel Polymer Electrolyte Containing Ionic Liquid Pyr1,4TFSI for Lithium Batteries Application

Macromolecular Rapid Communications, EarlyView.
The study develops gel polymer electrolytes using PVDF‐HFP copolymer, lithium salt, and an ionic liquid, evaluates how different solvents affect crystallinity, thermal stability, microstructure, and conductivity, observes a crystallinity decrease from 31% to 11%, identifies solvent‐dependent membrane morphologies, and reports the highest conductivity ...

Temperature Dependence of Paramagnetic Species in the Human Brain Tissue: An X‐Band EPR Study

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Paramagnetic ions are distributed throughout the human brain. The increased accumulation of these metals, such as iron and copper, can induce cellular death and the development of neurological diseases. Electron Paramagnetic Resonance (EPR) is a spectroscopic technique capable of detecting these ions in a given biological sample ...
