Exploring changes in lipid metabolism is helpful for providing unique insight into hepatocellular carcinoma (HCC) pathogenesis mechanisms and early hepatocarcinogenesis. However, lipid metabolism involves different omics molecular interactions by means of both linear and nonlinear forms. Thus, we proposed a novel network construction method based on molecular pair evaluation from linear and nonlinear viewpoints (PELN) for clinical studies.

Objective: Cranial nerves (CNs) play a crucial role in various essential functions of the human brain, and mapping their pathways from diffusion MRI (dMRI) provides valuable preoperative insights into the spatial relationships between individual CNs and key tissues. However, mapping a comprehensive and detailed CN atlas is challenging because of the unique anatomical structures of each CN pair and the complexity of the skull base environment.

Method: In this work, we present what we believe to be the first study to develop a comprehensive diffusion tractography atlas for automated mapping of CN pathways in the human brain.

Background: With the increasing greenhouse effect, there is growing concern about the correlation between the humid environment and the incidence of various diseases. A high-humidity environment may cause intestinal inflammation through bacterial colonization or contamination of water. Aquaporin-3 (AQP3) plays an important role in maintaining intestinal water transport, permeability, fluid secretion, and absorption homeostasis.

Background And Purpose: The oculomotor nerve (OCN) innervates the eye muscles and can be affected by inflammatory, compressive, and pathological conditions. Diffusion MRI (dMRI) tractography shows the potential ability to describe the trajectory of the OCN. However, reconstruction of the OCN in the cavernous sinus is still challenging due to the complex tissue environment at the skull base.

Uneven local electric fields and limited nucleation sites at the reaction interface can lead to the formation of hazardous lithium (Li) dendrites, posing a significant safety risk and impeding the practical utilization of Li metal anodes (LMAs). Here, we present a method utilizing atomic layer deposition (ALD) to create lithiophilic titanium nitride (TiN) sites on carbon nanotubes (CNTs) surfaces, integrated with nanocellulose to form a lithiophilic interlayer (NFCP@TN). This interlayer, which is highly flexible and electrolyte-wettable, functions as a current collector and host material for LMAs.

Background: Stroke is a major global health concern, particularly for women of childbearing age (WCBA), who face unique biological and sociodemographic risks. This study analyzes temporal trends in stroke incidence, prevalence, disability-adjusted life-year (DALY), and deaths among WCBA at global, regional, and national levels over the past three decades, using age-period-cohort (APC) modeling.

Methods: Stroke burden data for WCBA from 1992 to 2021 across 204 countries were extracted from the Global Burden of Disease (GBD) 2021 study.

Recently, the monkeypox virus (MPXV) outbreak was once again declared by the World Health Organization as a global health emergency, and currently, there is no specific drug against MPXV. During the replication cycle, MPXV produces two distinct forms of viral particles: extracellular enveloped virus (EEV), released via exocytosis, and intracellular mature virus (IMV), expelled through host cell lysis. A29 and B6 proteins are membrane proteins found on the IMV and EEV viral particles, respectively.

Aging populations are susceptible to climate change due to physiological factors and comorbidities. Most relevant studies reported the effect of temperature on cardiovascular disease (CVD)-related mortality in aging populations. However, the combined effects of temperature and humidity on CVD-related mortality remain unclear.

This study aimed to develop an automatic segmentation method for brainstem fiber bundles. We utilized the brainstem as a seed region for probabilistic tractography based on multishell, multitissue constrained spherical deconvolution in 40 subjects from the Human Connectome Project (HCP). All tractography data were registered into a common space to construct a brainstem fiber cluster atlas.

The emergence of monkeypox has become a global health threat after the COVID-19 pandemic. Due to the lack of available specifically treatment against MPV, developing an available vaccine is thus the most prospective and urgent strategy. Herein, a programmable macrophage vesicle based bionic self-adjuvanting vaccine (AM@AEvs-PB) is first developed for defending against monkeypox virus (MPV).

The widespread utilization of plastic and cobalt alloy products in industries and medicine has led to the increased presence of their degradation byproducts, microplastics (MPs), and cobalt nanoparticles (Co NPs), in the environment and organisms. While these particles can circulate throughout the body via the circulatory system, their specific adverse effects and mechanisms on the vascular system remain unclear. Employing scanning electron microscope (SEM) analysis and other methodologies, we demonstrate the potential adsorption and aggregation phenomena between MPs and Co NPs.

Many advanced super-resolution reconstruction methods have been proposed recently, but they often require high computational and memory resources, making them incompatible with low-power devices in reality. To address this problem, we propose a simple yet efficient super-resolution reconstruction method using waveform representation and multi-layer perceptron (MLP) for image processing. Firstly, we partition the original image and its down-sampled version into multiple patches and introduce WaveBlock to process these patches.

Mild traumatic brain injury (mTBI) is a known risk factor for neurodegenerative diseases, yet the precise pathophysiological mechanisms remain poorly understand, often obscured by group-level analysis in non-invasive neuroimaging studies. Individual-based method is critical to exploring heterogeneity in mTBI. We recruited 80 mTBI patients and 40 matched healthy controls, obtaining high-resolution structural MRI for constructing Individual Differential Structural Covariance Networks (IDSCN).

Acting as a growth regulator, Indole-3-acetic acid (IAA) is an important phytohormone that can be produced by several species. However, few studies have been published on the comprehensive evaluation of the strains for practical applications and the effects of selenium species on their IAA-producing ability. The present study showed the selenite reduction strain LH18, which is capable of producing selenium nanoparticles (SeNPs) at a high yield in a cost-effective manner.
