The causal relationship between anti-CD20 antibodies and endometrial cancer: a Mendelian randomization study.

Purpose: To determine the effects of anti-B cell surface marker CD20 antibody on the occurrence and progression of endometrial cancer to provide insights into clinical treatment in the future.

Methods: We performed a two-sample Mendelian randomization analysis (MR) to analyze the causal relationship between EC and immune cell markers. The genome-wide association study (GWAS) data of MS4A1 single nucleotide polymorphism encoding gene of CD20 were collected, and a drug target MR analysis was performed to detect the causal relationship between anti-CD20 antibody and the risk of EC.

Spousal collaboration mediates the relation between self-rated health and depressive symptoms of Chinese older couples: an actor-partner interdependence approach.

Background: Dyadic coping resources have been considered a potential explanatory mechanism of spousal interdependence in health, but the mediation of spousal collaboration for the relationship between self-rated health and depressive symptoms has yet to be examined. This study aimed to investigate the within- (actor effect) and between-partner effects of self-rated health on depressive symptoms in community-dwelling older couples facing physical functioning limitations and to examine the role of spousal collaboration in mediating the actor and cross-partner effects of self-rated health on depressive symptoms.

Method: Data from 185 community-dwelling older Chinese married couples were analyzed using the actor-partner interdependence mediation model (APIMeM).

Daytime Napping and Metabolic Syndrome: A 4-Year Follow-Up Study of Chinese Middle-Aged and Older Adults.

The current study examined the relationship between napping duration and metabolic syndrome (MetS) among Chinese middle-aged and older adults over 4 years. We included 4,526 individuals aged ≥50 years who completed the 2011 and 2015 waves of the China Health and Retirement Longitudinal Study. General linear models were conducted to analyze the association of napping duration (none, 1 to 29 minutes, 30 to 59 minutes, 60 to 89 minutes, and ≥90 minutes) with MetS.

Circ_0091579 enhances the malignancy of hepatocellular carcinoma via miR-1287/PDK2 axis.

Several articles have indicated that circular RNAs are involved in pathogenesis of human cancers. Nevertheless, the role of circ_0091579 in hepatocellular carcinoma (HCC) progression remains to be revealed. Quantitative reverse transcriptase polymerase chain reaction was carried out to examine the expression of circ_0091579 and miR-1287.

Bilayer ventilated labyrinthine metasurfaces with high sound absorption and tunable bandwidth.

The recent advent of acoustic metamaterials offers unprecedented opportunities for sound controlling in various occasions, whereas it remains a challenge to attain broadband high sound absorption and free air flow simultaneously. Here, we demonstrated, both theoretically and experimentally, that this problem can be overcome by using a bilayer ventilated labyrinthine metasurface. By altering the spacing between two constituent single-layer metasurfaces and adopting asymmetric losses in them, near-perfect (98.

Transparent and UV Blocking Structural Colored Hydrogel for Contact Lenses.

Usually, materials with perfect structures possess excellent properties, but it is not always the case. Here, a new approach is reported to construct structural colored hydrogel films with excellent ultraviolet (UV) blocking performance for contact lenses. The theoretical simulation predicts that with perfect periodic structures, the hydrogel films can strongly reflect incident light in a narrow visible wavelength range and thus exhibit extraordinarily brilliant colors.

Efficient terahertz and infrared Smith-Purcell radiation from metal-slot metasurfaces.

We demonstrate that when a charged particle moves on top of a metal-slot metasurface consisting of metallic slot resonators, strong Smith-Purcell electromagnetic (EM) radiation can be produced at resonant frequency. By adjusting the period of the metasurface, the resonant (or working) frequency can be tuned from gigahertz to terahertz and infrared regions. Since the EM field is localized in the slots rather than at the metal surface, the metasurfaces are found to exhibit a very low absorption loss ratio (<1%) in low working frequencies (<1  THz).
