Background: Brachial-ankle pulse wave velocity (baPWV) is an index for evaluating arterial stiffness and is recognized as an independent predictor of an impending cardiovascular event. Limited large-scale population data are available regarding the relationship between baPWV and the change in ideal cardiovascular health (CVH) status, particularly among Asians.
Methods: A random sample of 5199 participants (≥40 years of age; 40% women) was enrolled in a cross-sectional study in China to examine the association between ideal CVH and baPWV. Arterial stiffness was defined as a baPWV of 1400 cm/second or higher. Information on CVH was collected based on the American Heart Association's CVH definition by measuring all 7 components (nonsmoking status, body mass index, physical activity, healthy diet, normal total cholesterol, blood pressure, and fasting blood glucose), with 1 or 0 for each component, and a score from 0 to 7 for each participant.
Results: A significant and inverse association was found between the ideal CVH score and baPWV (P <.001). The adjusted odds ratios for arterial stiffness prevalence were .17 (95% confidence interval [CI], .11-.26), .26 (95% CI, .19-.35), .42 (95% CI, .32-.52), .54 (95% CI, .42-.69), and .69 (95% CI, .54-.89) for those with CVH scores of 7-6, 5, 4, 3, and 2, respectively, compared with those with a CVH score of 1-0 (P <.001). Similarly graded relationships were observed in different age and gender subgroups (P <.001).
Conclusion: The favorable score of ideal CVH was inversely related to baPWV in Chinese adults, supporting the use of ideal CVH metrics as a useful tool for public health efforts.

Graphene and its derivatives have been widely used as reinforcing nanofillers for high-performance polymer nanocomposites. The effectiveness of the reinforcement largely depends on the properties of the nanofiller-matrix interface, which can be represented by the interfacial shear strength (IFSS). This work systematically investigates IFSS enhancements for polyethylene (PE) nanocomposites reinforced by graphene origami (GOri) through molecular dynamics pull-out simulations.

Rice ( L.) is a staple food for more than half of the world's population, but its yields are increasingly threatened by environmental problems, including soil compaction. This problem limits root growth which limits water and nutrient foraging capacity thus reduces productivity due to, restricted diffusion of ethylene, a key plant hormone playing an important role in exacerbating these effects.

Background: To investigate the risk factors for readmission of elderly patients with coronary artery disease, and to construct and validate a predictive model for readmission risk of elderly patients with coronary artery disease within 3 years by applying machine learning method.
Methods: We selected 575 elderly patients with CHD admitted to the Affiliated Lu'an Hospital of Anhui Medical University from January 2020 to January 2023. Based on whether patients were readmitted within 3 years, they were divided into two groups: those readmitted within 3 years (215 patients) and those not readmitted within 3 years (360 patients).

At present, some progress has been made in developing NIR light-responsive free radical generators. However, the efficacy of theranostics continues to be hindered by tumor-associated inflammatory reactions. Hence, fulfilling the in situ release of free radicals upon NIR light excitation specifically activated by the inflammation microenvironment would be an ideal strategy for efficient inflammation eradication and tumor suppression but remains a challenge.
