    Abstract Eolian dust and riverine discharge are identified as two key components of terrestrial input to the oceans. They supply micronutrients to the oceans and modify marine carbon biogeochemistry and global climate through dust-land-ocean interactions. However, it is challenging to accurately constrain regional terrestrial inputs in the past, with currently available models and geochemical proxies. The present study utilizes sedimentary wtCaCO

  2. Article ; Online: A nomogram prediction model for refracture in elderly patients with osteoporotic vertebral compression fractures after percutaneous vertebroplasty.

    Abstract Background: This study aims to evaluate the risk factors of refracture in elderly patients with osteoporotic vertebral compression fracture (OVCF) patients after percutaneous vertebroplasty (PVP) and construct a predictive nomogram model.
    Methods: Elderly symptomatic OVCF patients undergoing PVP were enrolled and grouped based on the development of refracture within 1 year postoperatively. Univariate and multivariate logistic regression analyses were performed to identify risk factors. Subsequently, a nomogram prediction model was constructed and evaluated based on these risk factors.
    Results: A total of 264 elderly OVCF patients were enrolled in the final cohort. Among these, 48 (18.2%) patients had suffered refracture within 1 year after surgery. Older age, lower mean spinal BMD, multiple vertebral fracture, lower albumin/fibrinogen ratio (AFR), no postoperative regular anti-osteoporosis, and exercise were six independent risk factors identified for postoperative refracture. The AUC of the constructed nomogram model based on these six factors was 0.812 with a specificity and sensitivity of 0.787 and 0.750, respectively.
    Conclusions: In summary, the nomogram model based on the six risk factors had clinical efficacy for refracture prediction.

    Abstract This study explored the facial expression stereotypes of adult men and women within the Chinese cultural context and investigated whether adult participants had facial expression stereotypes of children aged 6 and 10 years old. Three experiments were conducted with 156 adult Chinese university student participants. Experiment 1 explored whether adult participants had facial expression stereotypes of adult men and women. In Experiment 1a, the participants imagined a happy or angry adult face and stated the gender of the imagined face. In Experiment 1b, the participants were asked to quickly judge the gender of happy or angry adult faces, and their response time was recorded. Experiments 2 and 3 explored whether adults apply the stereotypes of adult men and women to 10-year-old and 6-year-old children. Experiment 1 revealed that the participants associated angry facial expressions with men and happy facial expressions with women. Experiment 2 showed that the participants associated angry facial expressions with 10-year-old boys and happy expressions with 10-year-old girls. Finally, Experiment 3 revealed that the participants associated happy facial expressions with 6-year-old girls but did not associate angry facial expressions with 6-year-old boys. These results showed that, within the Chinese cultural context, adults had gender-based facial expression stereotypes of adults and 10-year-old children; however, the adult participants did not have gender-based facial expression stereotypes of 6-year-old male children. This study has important implications for future research, as adults' perceptions of children is an important aspect in the study of social cognition in children.

    Abstract Background: To identify some clinical and laboratory independent risk factors for postoperative recompression among elderly osteoporotic vertebral compression fractures (OVCF) patients.
    Methods: A retrospective analysis was conducted on 287 elderly OVCF patients after percutaneous vertebroplasty (PVP). Relevant risk factors for recompression were screened and further analyzed through multivariate logistic regression.
    Results: Within postoperative 1 year, recompression had occurred in 72 patients, with an incidence of 25.1% (72/287). Multivariate logistic analysis indicated that mean spinal BMD <  - 2.85 (OR: 4.55, 95%CI 2.22-9.31, P < 0.001), ODI ≥ 68.05% (OR: 6.78, 95%CI 3.16-14.55, P < 0.001), PNI score < 43.1 (OR: 2.81, 95%CI 1.34-5.82, P = 0.005), and mFI score ≥ 0.225 (OR: 8.30, 95%CI 3.14-21.95, P < 0.001) were four distinct risk factors that independently contributed to postoperative recompression.
    Conclusions: Spinal BMD, ODI, PNI and mFI independently predict recompression in OVCF patients after PVP treatment.

    Abstract Recent years have witnessed a growing interest in bio-based thermosetting resins in terms of environmental concerns and the desire for sustainable industrial practices. Beyond sustainability, utilizing the structural diversity of renewable feedstock to craft bio-based thermosets with customized functionalities is very worthy of expectation. There exist many bio-based compounds with inherently unique chemical structures and functions, some of which are even difficult to synthesize artificially. Over the past decade, great efforts are devoted to discovering/designing functional properties of bio-based thermosets, and notable progress have been made in antibacterial, antifouling, flame retardancy, serving as carbon precursors, and stimuli responsiveness, among others, largely expanding their application potential and future prospects. In this review, recent advances in the field of functional bio-based thermosets are presented, with a particular focus on molecular structures and design strategies for discovering functional properties. Examples are highlighted wherein functionalities are facilitated by the inherent structures of bio-based feedstock. Perspectives on issues regarding further advances in this field are proposed at the end.

    Abstract Welding is a key missing manufacturing technique in graphene science. Due to the infusibility and insolubility, reliable welding of macroscopic graphene materials is impossible using current diffusion-bonding methods. This work reports a pulsed laser welding (PLW) strategy allowing for directly and rapidly joining macroscopic 3D porous graphene materials under ambient conditions. Central to the concept is introducing a laser-induced graphene solder converted from a designed unique precursor to promote joining. The solder shows an electrical conductivity of 6700 S m

    Abstract In late 2020, the U.S. Food and Drug Administration (FDA) approved a lipid-based mRNA vaccine for the prevention of COVID-19, which has pushed this field to be more closely studied and motivated researchers to delve deeper into mRNA therapeutics. To date, the research on mRNA cancer vaccines has been developed rapidly, and substantial hopeful therapeutic results have been achieved against various solid tumors in clinical trials. In this review, we first introduce three main components of mRNA cancer vaccines, including mRNA antigens, adjuvants, and delivery vectors. Engineering these components can optimize the therapeutic effects of mRNA cancer vaccines. For instance, appropriate modification of mRNA structure can alleviate the poor stability and innate immunogenicity of mRNA, and the use of mRNA delivery vectors can address the issues of low delivery efficiency
