Predictive value of a constructed artificial neural network model for microvascular invasion in hepatocellular carcinoma: A retrospective study.

Background: Microvascular invasion (MVI) is a significant risk factor for recurrence and metastasis following hepatocellular carcinoma (HCC) surgery. Currently, there is a paucity of preoperative evaluation approaches for MVI.

Aim: To investigate the predictive value of texture features and radiological signs based on multiparametric magnetic resonance imaging in the non-invasive preoperative prediction of MVI in HCC.

"We Need Gentleness": Isolation, Loneliness, and Implications for Psychosocial Counseling Among People with HIV who are on Methadone Maintenance Treatment and Experience Common Mental Disorders in Vietnam.

The psychological experiences and needs of people with human immunodeficiency virus (HIV) who use methadone maintenance treatment and have common mental disorders in Hanoi, Vietnam remain unknown. Due to limited services for common mental disorders, optimal delivery methods for psychotherapy are also unknown. Accordingly, this qualitive study explored both symptoms of common mental disorders among this population and the preferred qualifications and characteristics of a mental health counselor.

Exclusive Generation of Single-Atom Sulfur for Ultrahigh Quality Monolayer MoS Growth.

Preparation of high-quality two-dimensional (2D) transition metal dichalcogenides (TMDCs) is the precondition for realizing their applications. However, the synthesized 2D TMDCs (e.g.

Reactivity and Stability of Reduced Ir-Weight TiO-Supported Oxygen Evolution Catalysts for Proton Exchange Membrane (PEM) Water Electrolyzer Anodes.

Reducing the iridium demand in Proton Exchange Membrane Water Electrolyzers (PEM WE) is a critical priority for the green hydrogen industry. This study reports the discovery of a TiO-supported Ir@IrO(OH) core-shell nanoparticle catalyst with reduced Ir content, which exhibits superior catalytic performance for the electrochemical oxygen evolution reaction (OER) compared to a commercial reference. The TiO-supported Ir@IrO(OH) core-shell nanoparticle configuration significantly enhances the OER Ir mass activity from 8 to approximately 150 A g at 1.

Arbuscular mycorrhizal symbiosis reshapes the drought adaptation strategies of a dominant sand-fixation shrub species in northern China.

Drylands are home to over 38 % of the world's population and are among the areas most sensitive to climate change and human activity. Most xerophytes rely on arbuscular mycorrhizal fungi (AMF) for improved drought tolerance. Although research has focused on crops and economically significant plants, the response of sand-fixation shrubs to AMF under drought conditions remains underexplored.
