Estrogen restores disordered lipid metabolism in visceral fat of prediabetic mice.

Background: Visceral obesity is increasingly prevalent among adolescents and young adults and is commonly recognized as a risk factor for type 2 diabetes. Estrogen [17β-estradiol (E2)] is known to offer protection against obesity diverse me-chanisms, while its specific effects on visceral adipose tissue (VAT) remain to be fully elucidated.

Aim: To investigate the impact of E2 on the gene expression profile within VAT of a mouse model of prediabetes.

Multiplexed rectangular dielectric gratings with multiple narrow-band refractive index filtering and sensing.

We propose a low-loss compound structure consisting of a multiplexed rectangular dielectric grating and a waveguide layer, which can function as multi-band optical filters and sensors in TE and TM polarization by utilizing the resonant mode of the waveguide (WG) and the hybrid SP, respectively. By manipulating the parameters and subsequently constraining the local density of multi-resonant modes to several distinct resonant wavelengths, we propose a novel category of highly sensitive refractive index sensing platforms. Spectral shifts ranging from 110 to 131 nm/RIU with FOM of (22, 26.
