Abstract: A method for regulating a downstream signaling pathway mediated by an activation of a trimethylamine-N-oxide includes administrating an omega-3 polyunsaturated fatty acid to a subject in need thereof. The omega-3 polyunsaturated fatty acid is for inhibiting an inflammatory response, for inhibiting an infection of a SARS-CoV-2 to a cell, for reducing an oxidative stress level in the cell, for alleviating an impairment of neovascularization, or for inhibiting a vascular fibrogenesis.

Abstract: A storage structure for a make-up powder applicator includes a hollow handle, a make-up powder applicator, and an elastic structure. The hollow handle has an accommodation space, and has an opening at one end thereof. The make-up powder applicator and the elastic structure are configured in the accommodation space. The elastic structure is located between a bottom of the make-up powder applicator and the hollow handle. With the accommodation space of the hollow handle and the elastic structure, the make-up powder applicator can be received in the hollow handle.
