Association of mitochondrial DNA copy number in peripheral blood with risk and prognosis in acute aortic syndrome.

Previous studies have reported that mtDNA-CN of blood was associated with a series of aging-related diseases. However, it remains unknown whether mtDNA-CN can be a potential biomarker of acute aortic syndromes (AAS). The mtDNA-CN in blood of 190 male patients with AAS and 207 healthy controls were detected by standardized qPCR-based assay.

Atomically Dispersed Co-P Moieties via Direct Thermal Exfoliation for Alkaline Hydrogen Electrosynthesis.

The development of highly active and stable cathodes in alkaline solutions is crucial for promoting the commercialization of anion exchange membrane (AEM) electrolyzers, yet it remains a significant challenge. Herein, we synthesized atomically dispersed CoP moieties (CoP-SSC) immobilized on ultrathin carbon nanosheets via a phosphidation exfoliation strategy at medium temperature. The thermodynamic formation process of the Co-P moieties was elucidated using X-ray absorption spectroscopy (XAS) and theoretical calculations.

Self-Foaming Expanded Ceramsites Prepared from Electrolytic Manganese Residue, Red Mud and Waste Soil.

In this study, in order to solve the problems of resource utilization of electrolytic manganese residue and the destruction of natural resources by the over-exploitation of raw materials of traditional ceramics, electrolytic manganese residue (EMR), red mud (RM), and waste soil (WS) were used to prepare self-foaming expanded ceramsite (SEC), and different firing temperatures and four groups with different mixing ratios of these three raw materials were considered. Water absorption, porosity, heavy metal ion leaching, and compressive strength in the cylinder of SEC were evaluated. The chemical composition and microscopic morphology of SEC were investigated by XRD and SEM.

The Impact of COVID-19 Pandemic on the Diagnosis, Treatment, and Outcomes of Colorectal Cancer in Singapore.

: During the COVID-19 pandemic, many countries implemented lockdowns and social distancing measures, which may delay the early diagnosis of colorectal cancer (CRC). This study aims to review the impact of the pandemic on the diagnosis and treatment outcomes of CRC. : Patients who underwent colonoscopy or surgery for CRC were included.

Child exposure to N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) and its derived quinone (6PPDQ) in e-waste areas: Urinary concentrations, sources, and health effect assessment.

N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine quinone (6PPDQ) and its parent 6PPD are ubiquitous in the environment and may induce multi-endpoint toxicity. Electronic waste (e-waste) dismantling is an under-recognized source of 6PPD and 6PPDQ emissions, and there is a lack of epidemiological investigations into their presence and health effects in local populations. This study aimed to determine the urinary concentrations of 6PPD and 6PPDQ in children aged 2-7 years from e-waste dismantling areas and evaluate their potential risk to physical growth.
