A deep understanding method of rare metal nanoparticle quantification throughout computed tomography.
This study demonstrated that the fabricated dually cross-linked, albumin-based hydrogels have great potential in such applications because they showed a low immune response, easy handling, full wound coverage, and tunable biodegradability. Precise spatial and controllable drug-release profiles may also be achieved via in situ transdermal post-tuning of the biomaterials, depending on the injury.The development of a facile synthesis and controllable layer stacking approach for covalent organic frameworks (COFs) is an important issue for modulating their properties and realizing their application diversity. Herein, three COF isomers with different stacking models (eclipsed AA, staggered AB, and ABC stacking) were obtained by modulating the reaction temperature and solvent medium. Experimental and theoretical calculations show that the ABC stacking isomer obtained at room temperature is the kinetic product, while the AA stacking isomer prepared by the solvothermal method is a thermodynamic product. Owing to the tautomerism involved in the reaction process, these isomers possess different ratios of enol and keto forms. Thus, they exhibit different generation efficiencies of Type I and Type II reactive oxygen species (ROS). The ABC stacking isomers could be employed as metal-free heterogeneous photocatalysts for visible-light-induced oxidation of amines to imines, owing to the highest generation efficiency of Type I ROS.The confirmation and regulation of active sites are particularly critical for the design of methanol oxidation reaction (MOR) catalysts. Here, an acid etching method for facet control combined with defect construction was utilized to synthesize Co3O4 nanoparticles on nickel foam for preferentially exposing the (311) facet with enriched oxygen vacancies (VO). The acid-leached oxides exhibited superior MOR activity with a mass activity of 710.94 mA mg-1 and an area-specific activity of 3.390 mA cm-2 as a result of (i) abundant active sites for MOR promoted by VO along with the highly active (311) facet being exposed and (ii) phase purification-reduced adsorption energy (Eads) of methanol molecules. Ex situ X-ray photoelectron spectroscopy proved that highly active CoOOH obtained via the activation of plentiful Co2+ effectively improved the MOR. Density functional theory calculations confirmed that the selective exposed (311) facet has the lowest Eads for CH3OH molecules. This work puts forward acid etching as the facet modification and defect engineer for nanostructured non-noble catalysts, which is expected to result in superior electrochemical performance required for advanced alkaline direct methanol fuel cells.Inhibiting the Nrf2Keap1 interaction to trigger cytoprotective gene expression is a promising treatment strategy for oxidative stress-related diseases. A short linear motif from Nrf2 has the potential to directly inhibit this protein-protein interaction, but poor stability and limited cellular uptake impede its therapeutic development. To address these limitations, we utilized an integrated molecular grafting strategy to re-engineer the Nrf2 motif. We combined the motif with an engineered non-native disulfide bond and a cell-penetrating peptide onto a single multifunctionalizable and ultrastable molecular scaffold, namely, the cyclotide MCoTI-II, resulting in the grafted peptide MCNr-2c. The engineered disulfide bond enhanced the conformational rigidity of the motif, resulting in a nanomolar affinity of MCNr-2c for Keap1. AZ-33 in vivo The cell-penetrating peptide led to an improved cellular uptake and increased ability to enhance the intracellular expression of two well-described Nrf2-target genes NQO1 and TALDO1. Furthermore, the stability of the scaffold was inherited by the grafted peptide, which became resistant to proteolysis in serum. Overall, we have provided proof-of-concept for a strategy that enables the encapsulation of multiple desired and complementary activities into a single molecular entity to design a Keap1-targeted inhibitor. We propose that this integrated approach could have broad utility for the design of peptide drug leads that require multiple functions and/or biopharmaceutical properties to elicit a therapeutic activity.In this issue, Bernard Choi and colleagues have presented their vision of clinical public health as an approach to address complex health issues in our health system. To help stimulate discussion, CIM invited commen-taries from two distinguished scientists to present their views on the concept. We hope this discussion will ultimately guide the direction public health will follow.
To solve complex health issues, an innovative and multidisciplinary framework is necessary. The Clinical Public Health (CPH) Division was established at the University of Toronto (UofT), Canada to foster inte-gration of primary care, preventive medicine and public health in education, practice and research. To better understand how the construct of CPH might be applied, we surveyed clinicians, researchers and public health professionals affiliated with the CPH Division to assess their understanding of the CPH concept and its utility in fostering broad collaboration.

A two-wave anonymous survey of the active faculty of the CPH Division, UofT was conducted across Canada. Wave 1 participants (n = 187; 2016) were asked to define CPH, while Wave 2 participants (n = 192; 2017) were provided a synthesis of Wave 1 results and asked to rank each definition. Both waves were asked about the need for a common definition, and to comment on CPH.

Response rates for the first and second waves were 25% and 22%, respectively. Of the six definitions of CPH from Wave 1, "the intersection of clinical practice and public health," was most highly ranked by Wave 2 participants. Positive perceptions of CPH included multidisciplinary collaboration, new fields and insights, forward thinking and innovation. Negative perceptions included CPH being a confusing term, too narrow in scope or too clinical.

The concept of Clinical Public Health can foster multidisciplinary collaboration to address com-plex health issues because it provides a useful framework for bringing together key disciplines and diverse professional specialties.
