A Microfabrication Technique for High-Performance Diffractive Optical Elements Tailored for Numerical Simulation.

Diffractive optical elements (DOEs) are specialized optical components that manipulate light through diffraction for various applications, including holography, spectroscopy, augmented reality (AR) and virtual reality (VR), and light detection and ranging (LiDAR). The performance of DOEs is highly determined by fabricated materials and fabrication methods, in addition to the numerical simulation design. This paper presents a microfabrication technique optimized for DOEs, enabling precise control of critical parameters, such as refractive index (RI) and thickness.

Polydopamine-Induced BMP7-Poly (Lactic-Co-Glycolic Acid)-Nanoparticle Coating Facilitates Osteogenesis in Porous Tantalum Scaffolds.

Bone defects are difficult to treat clinically and most often require bone grafting for repair. However, the source of autograft bone is limited, and allograft bone carries the risk of disease transmission and immune rejection. As tissue engineering technology advances, bone replacement materials are playing an increasingly important role in the treatment of bone defects.

Cellular senescence-associated genes in rheumatoid arthritis: Identification and functional analysis.

Rheumatoid arthritis (RA), a long-term autoinflammatory condition causing joint damage and deformities, involves a multifaceted pathogenesis with genetic, epigenetic, and immune factors, including early immune aging. However, its precise cause remains elusive. Cellular senescence, a hallmark of aging marked by a permanent halt in cell division due to damage and stress, is crucial in aging and related diseases.

Fluid volume status detection model for patients with heart failure based on machine learning methods.

Backgroud: Fluid volume abnormalities are a major cause of exacerbations in heart failure patients. However, there is few efficient, rapid, or cost-effective clinical approach for determining volume status, resulting in inadequate or unsatisfactory treatment. The aim was to develop an early fluid volume detection model for heart failure patients utilizing a machine learning stratification.

Impact of comprehensive thermal insulation on stress response and immune function in hysteroscopy patients: A retrospective study.

This retrospective study explores the impact of comprehensive thermal insulation measures on the stress response of patients undergoing hysteroscopy surgery. A total of 600 patients who underwent hysteroscopy at our hospital from January 2018 to December 2022 were included. Participants were randomly assigned to an observation group (n = 305) and a control group (n = 295).
