Expansion Microscopy (ExM) is a widely used super-resolution technique that enables imaging of structures beyond the diffraction limit of light. However, ExM suffers from weak labeling signals and expansion distortions, limiting its applica...
Photobiomodulation ameliorates ovarian aging by alleviating oxidative stress and inflammation damage and improving mitochondrial function [0.03%]
光生物调节通过减轻氧化应激和炎症损伤及改善线粒体功能来缓解卵巢衰老
Yu He,Rongan Ye,Yinbo Peng et al.
Yu He et al.
Ovarian aging is a serious clinical concern. Few safe and effective methods are currently available to improve ovarian functions. Photobiomodulation (PBM) is a safe and noninvasive physical therapy that can modulate a series of biological p...
The copepod Acartia spinicauda feeds less and dies more under the influences of solar ultraviolet radiation and elevated pCO2 [0.03%]
