The Anchor of Traditional Culture and Medical Students' Knowledge, Attitudes, and Willingness Towards Organ Donation during Internships: A Cross-Sectional Descriptive Study.

Objectives: The purpose of this study was to understand the knowledge, attitudes, and willingness of medical students in their clinical internships towards organ donation and to assess how traditional oriental culture plays a role.

Methods: This study conducted an online cross-sectional survey using a cell phone application with a self-designed questionnaire based on the Delphi method. This study was conducted among medical students in their internships in hospitals in nearly 20 provinces of China.

Development and validation of a nomogram model to predict primary graft dysfunction in patients after lung transplantation based on the clinical factors.

Background: Primary graft dysfunction (PGD), a significant complication that can affect patients' prognosis and quality of life, develops within 72 h post lung transplantation (LTx). Early detection and prevention of PGD should be given special consideration. The purpose of this study was to create a clinical prediction model to forecast the occurrence of PGD.

Constraints on Spin-Spin Velocity-Dependent Interactions.

The existence of exotic spin-dependent forces may shine light on new physics beyond the standard model. We utilize two iron shielded SmCo_{5} electron-spin sources and two optically pumped magnetometers to search for exotic long-range spin-spin velocity-dependent force. The orientations of spin sources and magnetometers are optimized such that the exotic force is enhanced and common-mode noise is effectively subtracted.

Asymmetric Bargaining Model for Water Resource Allocation over Transboundary Rivers.

Sustainable transboundary water governance is often challenged by conflicts between agents, which necessitates the design of cooperative and self-enforcing alternatives to facilitate equitable water distribution. The Nash bargaining approach, which originated from game theory, could offer a good mathematical framework to simulate strategic interactions among involved agents by considering individual rational benefits. Given that river-sharing problems often involve multiple self-interested agents, the asymmetric Nash bargaining solution (ANBS) could be used to describe agents' powers, as determined by disparate social, economic, and political as well as military status, and ensure win-win strategies based on individual rationality.

[The effects of dentists'performance on the clinical effects of root canal preparation].

Purpose: To evaluate the effects of dentists'performance on the clinical efficacies of root canal preparation.

Methods: 164 teeth, including 66 vital teeth and 98 necrotic pulp teeth , were divided into two groups in random. All the root canals were prepared using ProTaper nickel-titanium rotary by two dentists with junior senior qualification.

[A study on the accuracy of electronic root canal length measurement and its influential factors].

Purpose: To study the accuracy of JUSTY-II electronic apex locator and the influential factors on the accuracy of root canal working length measurement.

Methods: 148 teeth, including 71 teeth with pulpitis, 46 with necrotic pulp and 31 with apical periodontitis, were divided into two groups in random. The accuracy of electronic root canal working length measurement group was compared with that of the manual measurement group by Chi(2) test.

[Clinical study of the effect of preventing dentine hypersensitiveness by using Fluor Protector and Green Or on the prepared vital pulp abutment teeth].

Purpose: To study and evaluate the effect preventing dentine hypersensitiveness by using Fluor Protector or Green Or on the prepared vital pulp abutment teeth of PFM bridges.

Methods: 118 cases, 246 prepared vital pulp abutment teeth, were randomly divided into three groups: Experimental Group A--treated with the Fluor Protector and temporary crown; Experimental Group B--treated with the Green Or and temporary crown, and Control Group--only using temporary crown. The results of desensitization in 3 groups were evaluated.

[A comparison of the effect between Vitapex paste and antibiotic paste in apexification.].

Purpose: To study the effects of two root canal filling material in the apexification.

Methods: 172 juvenile permanent teeth,including 62 teeth with pulpitis, 32 teeth with necrotic pulp and 78 teeth with periapical periodontitis, were divided into two groups.The root canal was filled with Vitapex paste and antibiotic paste.
