Associations Between Complement C4, Habitual Constipation, and Sleep Disturbance in Oldest-Old and Centenarian Chinese Adults.

Background: Sleep disturbance is an immune-related disease, and the gut-brain axis is an important regulatory pathway. This cross-sectional study was designed to address these associations between complement C4, habitual constipation, and sleep disturbance and presents a reference for prevention and treatment of sleep disturbance.

Methods: Based on the China Hainan Centenarian Cohort Study, Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep disturbance following standard procedure.

Association of the triglyceride glucose index with obesity indicators and hypertension in American adults based on NHANES 2013 to 2018.

This cross-sectional study aimed to investigate the association between the TyG index and both obesity indicators and hypertension among American adults. Data were drawn from 4,813 adults in the 2013-2018 National Health and Nutrition Examination Survey (NHANES). Multivariate logistic regression models indicated significant associations between TyG and obesity-related indices with hypertension.

Resonantly Enhanced Hybrid Wannier-Mott-Frenkel Excitons in Organic-Inorganic Van Der Waals Heterostructures.

Hybrid excitons formed via resonant hybridization in 2D material heterostructures feature both large optical and electrical dipoles, providing a promising platform for many-body exciton physics and correlated electronic states. However, hybrid excitons at organic-inorganic interface combining the advantages of both Wannier-Mott and Frenkel excitons remain elusive. Here, hybrid excitons are reported in the copper phthalocyanine/molybdenum diselenide (CuPc/MoSe) heterostructure (HS) featuring strong molecular orientation dependence by low-temperature photoluminescence and absorption spectroscopy.

Clinical diagnosis of cerebral amyloid angiopathy related hemorrhage in China: Simplified Edinburgh criteria and Boston criteria version 2.0.

Background: Accurate diagnosis of cerebral amyloid angiopathy (CAA) in surviving patients is indispensable for making treatment decisions and conducting clinical trials. We aimed to evaluate the diagnostic value and clinical utility of the simplified Edinburgh computed tomography (CT) criteria for CAA-related hemorrhage in Chinese patients.

Methods: We analyzed 212 patients with lobar hemorrhage who underwent brain CT and magnetic resonance imaging (MRI) from a multicentre cohort.

Selective production of olefins from methanol over a heteroatomic SAPO-34 zeolite.

The methanol-to-olefins (MTO) process has the potential to bridge future gaps in the supply of sustainable lower olefins. Promoting the selectivity of propylene and ethylene and revealing the catalytic role of active sites are challenging goals in MTO reactions. Here, we report a novel heteroatomic silicoaluminophosphate (SAPO) zeolite, SAPO-34-Ta, which incorporates active tantalum(V) sites within the framework to afford an optimal distribution of acidity.
