Ultrahigh Specific Strength by Bayesian Optimization of Carbon Nanolattices.

Nanoarchitected materials are at the frontier of metamaterial design and have set the benchmark for mechanical performance in several contemporary applications. However, traditional nanoarchitected designs with conventional topologies exhibit poor stress distributions and induce premature nodal failure. Here, using multi-objective Bayesian optimization and two-photon polymerization, optimized carbon nanolattices with an exceptional specific strength of 2.

A new approach for hemodynamics of varicoceles: blood flow patterns based on contrast-enhanced ultrasound.

Background: Hemodynamic alterations in the spermatic vein are implicated in infertility among patients with varicocele (VC). Contrast-enhanced ultrasound (CEUS), a powerful tool for hemodynamic analysis, remains unexplored for VC. This study aimed to demonstrate the feasibility of using CEUS to evaluate spermatic vein hemodynamics in patients with VC and establish a clear correlation between specific hemodynamic patterns and impaired semen parameters.

Epidemiology and genotypic diversity of duck hepatitis B virus identified from waterfowl in partial areas of Guangdong province, Southern China.

Duck Hepatitis B virus (DHBV) infection model is extensively utilized as an animal model for studying human hepatitis B virus infection and for comparative research. 557 liver samples from geese and ducks were collected in parts of Guangdong province, southern China. The overall prevalence of DHBV was 45.

Evaluation of the Effect of Exosomes From Adipose Derived Stem Cells on Changes in GSH/ROS Levels During Skin Photoaging.

Objective: Exosomes (Exos) from adipose derived stem cells (ADSCs) can delay skin photoaging, but their effects on reactive oxygen species (ROS) remains unclear. This study aimed to investigate the relationship between adipose derived stem cell exosomes (ADSCs-Exos) in anti-photoaging of skin and glutathione (GSH)/ ROS expression in human fibroblasts.

Methods: A skin photoaging model was established by irradiating human fibroblasts with ultraviolet B (UVB) light in vitro.

Prediction of early lung adenocarcinoma spread through air spaces by machine learning radiomics: a cross-center cohort study.

Background: Sublobar resection is suitable for peripheral stage I lung adenocarcinoma (LUAD). However, if tumor spread through air spaces (STAS) present, the lobectomy will be considered for a survival benefit. Therefore, STAS status guide peripheral stage I LUAD surgical approach.
