Controllability of Graphene Oxide Doxorubicin Loading Capacity Based on Density Functional Theory.

Graphene can be used as a drug carrier of doxorubicin (DOX) to reduce the side effects of doxorubicin. However, there is limited research on the surface chemical modifications and biological effects of graphene oxide (GO). Therefore, it is necessary to explore the DOX affinity of different oxygen-containing functional groups in the graphene system.

Bias Evaluation of the Accuracy of Two Extraoral Scanners and an Intraoral Scanner Based on ADA Standards.

The spread and application of computer-aided design/computer-aided manufacturing (CAD/CAM) technology have contributed to the rapid development of digitalization in dentistry. The accuracy of scan results is closely related to the devising subsequent treatment plans and outcomes. Professional standards for evaluating scanners are specified in the American National Standard/American Dental Association Standard 132 (ANSI/ADA No.

Research of weak interaction between water and different monolayer graphene systems.

Weak interactions play a very important role in the fields of supramolecular chemistry, molecular physics, materials science, etc. They have a great impact on the structure of the compounds in the gas, liquid and solid phases and the mechanism of some reaction processes. In this study, we visualized the intermolecular interactions between HO and different graphene systems through density functional theory.

MBD3 mediates epigenetic regulation on EPAS1 promoter in cancer.

Hypoxia-inducible factor 2α (HIF2α) plays critical roles in cancer progression. Although the mechanisms of HIF2α translation and degradation have been well studied, the mechanism for HIF2α regulation at transcriptional level is still not fully understood. Here, we present evidence that DNA methylation in promoter contributes to transcription of EPAS1 coding HIF2α.
