While the impact of macronutrients on health is well-understood, the influence of micronutrients such as copper on cardiovascular health remains less explored. Copper, vital for heart function and antioxidant defense, may affect cardiovascular health through its role in enzymatic activities that reduce oxidative stress. This study evaluates the relationship between dietary copper intake and cardiovascular outcomes in hypertensive patients using data from the National Health and Nutrition Examination Survey (NHANES) from 2001 to 2018.

The body's geometrical relationship with the terrain is important for depth perception of human and non-human terrestrial animals. Static human observers in the dark employ the brain's internal model of the terrain, the intrinsic bias, to represent the ground as an allocentric reference frame for coding distance. However, it is unknown if the same ground-based coding process operates when observers walk in a cue-impoverished environment with visible ground surface.

This study aims to develop a novel segmentation method that utilizes spatio-temporal information for segmenting two-dimensional thyroid nodules on dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). Leveraging medical morphology knowledge of the thyroid gland, we designed a semi-supervised segmentation model that first segments the thyroid gland, guiding the model to focus exclusively on the thyroid region. This approach reduces the complexity of nodule segmentation by filtering out irrelevant regions and artifacts.

Objective: The study aimed to develop machine learning (ML) models to predict the mortality of patients with acute gastrointestinal bleeding (AGIB) in the intensive care unit (ICU) and compared their prognostic performance with that of Acute Physiology and Chronic Health Evaluation II (APACHE-II) score.

Methods: A total of 961 AGIB patients admitted to the ICU of Renmin Hospital of Wuhan University from January 2020 to December 2023 were enrolled. Patients were randomly divided into the training cohort (n = 768) and the validation cohort (n = 193).

Engineering hollow fibers with precise surface microstructures is challenging; yet, essential for guiding cells alignment and ensuring proper vascular tissue function. Inspired by Euplectella sponges, a novel strategy to engineer biomimetic hollow fibers with spiral surface microstructures is developed. Using oxidized bacterial cellulose, bacterial cellulose, and polydopamine, a "brick-and-mortar" scaffold is created through precise shear control during microfluidic coaxial spinning.

A 56-year-old woman was admitted to our hospital, presenting with a history of recurrent fevers persisting for over 2 months. The febrile episode was self-limiting, accompanied by cough without significant expectoration, with the fever predominantly manifesting during the afternoon and evening hours. Furthermore, there were no concurrent symptoms indicative of chest tightness, wheezing, dyspnea, or hemoptysis.

Purpose: This study aims to investigate the relationship between glycemic control and epidemiological characteristics of patients infected with carbapenem-resistant (CRKP), to identify mortality risk factors associated with CRKP infection, and to evaluate the impact of glucose on the resistance of CRKP to polymyxin and serum killing.

Patients And Methods: Clinical cases of 218 patients infected with CRKP were collected from a large tertiary public hospital in Anhui Province. We analyzed whether the glycemic control impacts the clinical and laboratory manifestations of infected patients.

Background: Cervical cancer remains a critical global health issue, responsible for over 600,000 new cases and 300,000 deaths annually. Pathological imaging of cervical cancer is a crucial diagnostic tool. However, distinguishing specific areas of cellular differentiation remains challenging because of the lack of clear boundaries between cells at various stages of differentiation.

Monolithic all-perovskite tandem solar cells present a promising approach for exceeding the efficiency limit of single-junction solar cells. However, the substantial open-circuit voltage loss in the wide-bandgap perovskite subcell hinders further improvements in power-conversion efficiency. Here we develop wide-bandgap perovskite films with improved (100) crystal orientation that suppress non-radiative recombination.

Background: The myriad implications of heavy metal pollution on human health have garnered substantial attention within the academic domain. Nevertheless, a notable research gap persists, as there is currently insufficient direct investigation elucidating the intricate interplay between nickel exposure and the risk of metabolic dysfunction-associated steatotic liver disease (MASLD).

Methods: The data utilized in this study was sourced from the National Health and Nutrition Examination Survey 2017-2020.

A multi-scale model is crucial for combining experiments and simulations to reveal the energy storage mechanism. As novel electrode materials, conductive metal-organic frameworks (c-MOFs) provide an ideal platform for understanding the energy storage process in supercapacitors. However, the prevailing circuit models lack consideration of the distinctive transmission path of c-MOFs, which hinders accurate descriptions of c-MOF supercapacitors.

Background: Amide proton transfer weighted (APTw) imaging has demonstrated extensive clinical applications in diagnosing, treating evaluating, and prognosis prediction of breast cancer. There is a pressing need to automatically segment breast lesions on APTw original images to facilitate downstream quantification, which is however challenging.

Purpose: To build a segmentation model on the original images of APTw imaging sequence by leveraging the varying contrasts between breast lesions and their surrounding glandular and fat tissues displayed on the original images of APTw imaging at different frequency offsets.

Uncontrolled hemorrhage, especially in non-compressible and deep wounds, remains a critical issue in emergency and surgical care. Existing hemostatic powders often lack rapid gelation, mechanical robustness, and adequate adherence, increasing the risk of rebleeding under high-pressure blood flow. To address these limitations, PQPP, a novel self-gelling hemostatic material composed of polyacrylamide/quaternized chitosan coacervates and polydopamine nanoparticles is developed.

Although our understanding of the molecular biology of Alzheimer's disease (AD) continues to improve, the etiology of the disease, particularly the involvement of gut microbiota disturbances, remains a challenge. Outer membrane vesicles (OMVs) play a key role in central nervous system diseases, but the impact of OMVs on AD progression remains unclear. In this study, we hypothesized that AD-derived OMVs (OMVs) were a risk factor in AD pathology.
