Application of MSCT Image Post-Processing Techniques in the Identification of Rib Fracture Malunion.

Objectives: To compare the application value of three image post-processing techniques volume rendering (VR), multiplanar reformation (MPR) and curved planar reformation (CPR) in the identification of rib fracture malunion.

Methods: The types and numbers of rib fracture malunion in 75 patients were recorded, and the sensitivity, specificity, accuracy and Youden index of VR, MPR and CPR in the diagnosis of rib fracture malunion were compared. Receiver operator characteristic (ROC) curve was drawn and area under the curve (AUC) was calculated, and the detection rates of three image post-processing techniques for different types of rib fracture malunion were compared.

Preparation of restricted-access boronate affinity adsorbent with excellent anti-protein adsorption property for directly extracting small cis-diol molecules from biological matrices.

Boronate affinity adsorbents are of great promise in the enrichment of small cis-diol-containing molecules (cis-diols) from biological matrices. This work develops a restricted-access boronate affinity mesoporous adsorbent, in which boronate sites are only distributed on the internal surface of mesopores and the external surface is a strongly hydrophilic layer. The adsorbent has high binding capacities (30.

Hierarchical Mesoporous Metal-Organic Frameworks with Boric Acid Sites on the Inner Surface of Small Mesopores for the Extraction of Nucleotides in Human Plasma Samples.

In this work, a boronate affinity-functionalized hierarchical mesoporous metal-organic framework adsorbent with boronate sites only in the small mesopore has been structured based on UiO-66@FeO. The introduction of large mesopores in the adsorbent can promote the diffusion of small -diol-containing compounds (-diols) into small mesopore channels, and the removal of the adsorption sites on the external surface of materials and in large mesopores can enhance the size-exclusion effect of the adsorbent. In addition, the adsorbent has faster adsorption kinetics and excellent selectivity to small -diols.

Relationship between the Height of Alveolar Bone Resorption and Sex and Age in Adolescents.

Objectives: To explore the relationship between the height of alveolar bone resorption and sex and age in the adolescent dentition.

Methods: Multi-slice computed tomography (MSCT) was used to measure the height of alveolar bone resorption at labial, lingual, mesial and distal sites of teeth in 149 adolescents aged from 10 to 20 years. SPSS 25.
