1275‐nm Photobiomodulation Alleviates Brain Drainage Impairment as a Promising Therapeutic Strategy for Aging‐Related Neurological Decline

Aging Cell, Volume 24, Issue 12, December 2025.
Noninvasive 1275‐nm photobiomodulation improves brain drainage and promotes lymphatic clearance of advanced glycation end products (AGEs) in an aging model (AM) in male mice. These effects are associated with nitric oxide release‐mediated dilation of meningeal lymphatic vessels (MLVs).

Detecting synchronization of self-sustained oscillators by external driving with varying frequency

, 2006
We propose a method for detecting the presence of synchronization of self-sustained oscillator by external driving with linearly varying frequency. The method is based on a continuous wavelet transform of the signals of self-sustained oscillator and ...

Topological phase structures of conical refraction beams: expanding orbital angular momentum applications for nanoscale biosensing

Nanophotonics, Volume 14, Issue 24, Page 4447-4457, December 2025.
Abstract Topologically structured light carrying orbital angular momentum (OAM) has emerged as a powerful tool for nano‐photonics and biomedical optics, yet conventional integer‐charge Laguerre–Gaussian (LG) beams suffer from rotational degeneracy that limits diagnostic precision.

Fluorescent and Chemiluminescent Dyes with Aryl Phthalimide and Aryl Luminol Chromophores

ChemPhotoChem, Volume 9, Issue 8, August 2025.
A series of photo‐active phthalimides and luminols is prepared by an arylation method from a key precursor. Significant stereoelectronic correlation of the aromatic substituents with the photophysical properties is documented. A new arylated luminol derivative shows a more than three times higher ΦCL than the parent luminol.
