Background And Aim: The analyses of longitudinal changes in remnant cholesterol (RC) and cardiovascular disease (CVD) remains are limited. The objective of the study was to investigate the associations of longitudinal changes in RC with the risks of CVD and its subtypes (myocardial infarction [MI] and stroke).

Methods And Results: The participants were enrolled in the Kailuan study. The RC short-term change pattern was defined by RC cutoff points according to equivalent percentiles for low-density lipoprotein cholesterol of 2.6 mmol/L at visits in 2006 and 2008. The RC long-term change pattern was defined as the RC trajectories from 2006 to 2010. Multivariate Cox proportion models were used to calculate hazard ratios (HRs) and their 95% confidence intervals (CIs). The cutoff values of RC were 0.52 mmol/L at the 2006 visit and 0.51 mmol/L at the 2008 visit. In the RC short-term change analysis, the participants in the high stable group had a 31% increased risk of CVD (HR 1.31; 95% CI 1.22-1.41), 73% increased risks of MI (HR 1.73; 95% CI 1.47-2.03), and 21% increased risks of stroke (HR 1.21; 95% CI 1.12-1.31) compared with participants in the low stable group. Three RC trajectories were employed in the RC long-term change analysis. Compared with the low stable group, the high stable group had a 1.34-fold risk of CVD (HR 1.34; 95% CI 1.17-1.53), 1.66-fold risk of MI (HR 1.66; 95% CI 1.24-2.21), and 1.22-fold risk of stroke (HR 1.22; 95% CI 1.05-1.42).

Conclusions: The stable high RC was associated with a higher risk of CVD. Maintaining optional RC levels could reduce the lifetime risk of CVD and prolong the year of life free from CVD.

To investigate the effect of the filter device on the cleanliness of molten steel and the flow field distribution within the tundish. The tundish filters were designed into five groups of pores with 20°, 25°, 30°, 35° and 40° elevation angles, and the flow field distribution and impurity removal rate of molten steel were calculated by Discrete Phase Model (DPM). The results showed that the removal rate of impurity in the molten steel could be significantly improved by using the tundish filter with elevation angle.

Background: Brain metastases (BMs) are common in human epidermal growth factor receptor 2 (HER2)-positive advanced breast cancer, increasing morbidity and mortality. Systemic therapy for BMs can be effective, with the triple combination of trastuzumab, capecitabine, and tucatinib being a potential standard. More recently, intracranial activity of antibody-drug conjugates has been reported, but the size of individual studies has been small.

Comparison of microplastics heteroaggregation with MoS and graphene oxide nanosheets: Dependence on the configuration and impacts on aquatic transport.

Electronic address:

Understanding the behavior and fate of microplastics (MPs) in aquatic environment is crucial for assessing their potential risks. This study investigated the heteroaggregation behaviors of MPs with representative 2D nanosheets, MoS and graphene oxide (GO), under various conditions, focusing on the transport behavior of the resulting aggregates. It was found that the destabilization capabilities of 2D nanosheets are notably stronger than those of well-reported nanoparticles.

Benzene reduction by molecular complexes remains an important synthetic challenge, requiring harsh reaction conditions involving group I metals. Reductions of benzene, to date, typically result in a loss of aromaticity, although the benzene tetra-anion, a 10π-electron system, has been calculated to be stable and aromatic. Due to the lack of sufficiently potent reductants, four-electron reduction of benzene usually requires the use of group I metals.
