A Novel Model for Cornea Power Shift in Eyes Wearing Orthokeratology Lenses With Different Back Optic Zone Diameters for Myopia Control.

Purpose: The purpose of this study was to quantify the corneal power changes after wearing orthokeratology lenses of different back optic zone diameters (BOZDs) and to propose a novel 4-parameter model capable of revealing the associations between each parameter and axial length growth (ALG).

Methods: A prospective self-controlled study was conducted between June 2022 and December 2023. One eye in each subject (N = 33) was randomly assigned to wear a lens with a BOZD of either 5 mm (5 oz) or 6 mm (6 oz).

Impact of aortic branch retention strategies on thrombus growth prediction in type B aortic dissection: A hemodynamic study.

Background: Type B Aortic Dissection (TBAD) is a serious cardiovascular condition treated effectively by TEVAR (Thoracic Endovascular Aortic Repair), which promotes false lumen thrombosis with minimal invasiveness. However, the impact of aortic branch retention strategies on thrombus growth prediction is often underestimated.

Method: This study numerically investigated four branch retention strategies: preserving all branches (Type 1 strategy), removing all branches (Type 2 strategy), removing only the aortic arch branches (Type 3 strategy), and removing only the abdominal aortic branches (Type 4 strategy).

Cerebral Blood Flow Changes and Their Spatial Correlations With GABAa and Dopamine-D1 Receptor Explaining Individual Differences in Chronic Insomnia and the Therapeutic Effects of Acupuncture.

This study integrated neuroimaging and neurochemistry data to explore brain mechanisms in chronic insomnia disorder (CID) and the neuromodulatory effects of acupuncture. We analyzed a cross-sectional arterial spin labeling (ASL) dataset (N = 197) of CID patients and healthy controls to identify cerebral blood flow (CBF) changes. Additionally, a longitudinal ASL dataset (N = 44) examined CBF changes in CID patients after a 4-week acupuncture treatment or on a waitlist.

In Situ Probing Dynamic Exsolution of Fe from Perovskite under Graded Potentials.

Metal exsolution from perovskite oxides offers a promising approach to developing highly active catalysts. Voltage-driven exsolution achieves a faster rate and better dispersion of the nanoparticles. However, the impact of the external voltage on the dynamic of metal exsolution remains unclear.

Formation of CdTeS Prenucleation Clusters at Elevated Temperatures and Transformation to Magic-Size Clusters at Room Temperature.

The synthesis of colloidal semiconductor magic-size clusters (MSCs) of ternary II-VI metal chalcogenide (MEE) remains challenging. Using CdTeS as a model system, it is shown that CdTeS MSC-381 (displaying sharp optical absorption peaking at 381 nm) develops at room temperature from prenucleation-stage samples of reactions of Cd(OAc)/OLA (cadmium acetate in oleylamine), TeTOP (tri-n-octylphosphine telluride), and S (sulfur). It is proposed that the three precursors experience physical co-self-assembly followed by the formation of Te-Cd-S covalent bonds inside each assembly.

Juxtaposing the antibacterial activities of different ZIFs in photodynamic therapy and their oxidative stress approach.

Instigating oxidative stress is a crucial aspect of antibacterial therapy. Yet, its behavior is poorly understood in the context of zeolitic imidazolate frameworks (ZIFs) - a group of highly promising antibacterial agents. To address this gap, a series of ZIF@Ce6 particles were synthesized to investigate the impact of particle shape, size, and metal ion type on oxidative stress and bactericidal activity.

Clinical and immunological characteristics of high-risk double-hit multiple myeloma.

At present, the characteristics of double-hit multiple myeloma (DHMM) are unknown. We retrospectively analyzed the clinical data from 433 new diagnosed MM patients and found that DHMM have a higher β2-MG level and percentage of bone marrow plasma cell. Cox regression analysis showed that the prognosis of DHMM was not limited by clinical indicators.

Enhancing tunnel crack detection with linear seam using mixed stride convolution and attention mechanism.

Cracks in tunnel lining structures constitute a common and serious problem that jeopardizes the safety of traffic and the durability of the tunnel. The similarity between lining seams and cracks in terms of strength and morphological characteristics renders the detection of cracks in tunnel lining structures challenging. To address this issue, a new deep learning-based method for crack detection in tunnel lining structures is proposed.
