Scaling Behavior and Conductance Mechanisms of Ion Transport in Atomically Thin Graphene Nano/Subnanopores.
Nano Lett
January 2025
The Key Laboratory of Weak Light Nonlinear Photonics, Ministry of Education, School of Physics and Teda Applied Physics Institute, Renewable Energy Conversion and Storage Center, State Key Laboratory of Photovoltaic Materials and Cells, Nankai University, Tianjin 300071, China.
Ion transport through atomically thin nano/subnanopores, such as those in monolayer graphene, presents challenges to traditional ion conduction models, primarily due to extreme confinement effects and hydration interactions. Under these conditions, existing models fail to account for conductance behaviors at the nano- and subnanometer scales. In this study, we perform a combined experimental and theoretical investigation of ion transport in monolayer graphene nano/subnanopores across varying salt concentrations.

Eur J Obstet Gynecol Reprod Biol X
March 2025
Department of Gynaecology, The First Affiliated Hospital of Shenzhen University/Shenzhen Second People's Hospital, Guangdong, China.
Background: Physical activity during pregnancy is a positive behavior for improving pregnancy outcomes, yet the relationship between physical activity during pregnancy and labor is still debated.
Objective: This study aimed to test our hypothesis that a higher level of physical activity during pregnancy is associated with a shorter labor duration.
Study Design: This was a prospective cohort study of pregnant women with singleton pregnancies and no contraindications to physical activity during pregnancy.
Association of the Triglyceride-Glucose Index and Obesity Indicators with Multiple Chronic Diseases: A Longitudinal Cohort Study Based on CHARLS.
J Multidiscip Healthc
January 2025
School of Medical Laboratory Medicine, Youjiang Medical University for Nationalities, Baise, Guangxi, 533000, People's Republic of China.
Objective: To explore the relationship between triglyceride glucose (TyG) and the obesity combined indexes and the occurrence of multiple chronic diseases (MCD), which will help to provide a basis for the prevention and treatment of this condition.
Methods: 3037 participants in the China Health and Retirement Longitudinal Study, which was conducted from 2011 to 2015 were selected for this study. They were divided into four groups (Q1, Q2, Q3, Q4) based on the quartiles of TyG, TyG-BMI, TyGWC and TyGWHtR in the baseline data.
Associations between Life's Essential 8 and liver function: a cross-sectional study.
Front Nutr
January 2025
Fangchenggang Hospital of Traditional Chinese Medicine, Fangchenggang, Guangxi, China.
Background: Life's Essential 8 (LE8) score, developed by the American Heart Association, assesses cardiovascular health using eight components: diet, physical activity, nicotine exposure, sleep health, body mass index, lipids, blood glucose, and blood pressure. Liver function is a critical indicator of overall health, with impairments linked to numerous chronic diseases. While the LE8 score has been extensively studied in relation to cardiovascular outcomes, its association with liver function remains underexplored.

January 2025
Federal University of São Carlos, São Paulo, Brazil. Department of Physiotherapy.
Context: Tendon abnormalities on imaging are commonly observed in individuals with Achilles tendinopathy. Those abnormalities can also be present in asymptomatic individuals, which is an important risk factor for developing tendon symptoms. Ballet dancers are particularly vulnerable due to the high loads placed on their Achilles tendons.
