[A randomized controlled trial of iRoot BP Plus used as pulp capping agent in the complex fracture of young permanent tooth].

Objective: To investigate the clinical and radiographic outcomes of 3 years after partial pulpotomy with iRoot BP Plus in immature permanent teeth with complex crown fracture and to provide refe-rence for the clinical application.

Methods: The study was prospectively designed and 104 immature permanent teeth with complex crown fracture were randomly allocated into two groups (=52). The experiment group received iRoot BP Plus as the pulp capping agent while the control group received calcium hydroxide as the pulp capping agent.

Preparation and Evaluation of a Combination of Chelating Agents for the Removal of Inhaled Uranium.

Inhalation of aerosolized uranium is recognized as a principal mode of exposure, posing significant risks of damage to the lungs, kidneys, and other vital organs. To enhance nuclide elimination from the body, chelating agents are employed; however, single-component chelators often exhibit limited spectral activity and low effectiveness, resulting in toxicologically relevant concentrations. We have developed a composite chelating agent composed of 3,4,3-Li(1,2-HOPO), DFP, and HEDP in optimized ratios, demonstrating marked improvements in eliminating inhaled uranium.

Incremental prognostic value of pericoronary adipose tissue attenuation beyond conventional features in patients with nonobstructive coronary artery disease.

Background And Aims: It remains uncertain whether pericoronary adipose tissue attenuation (PCATa) is associated with clinical outcome in patients with nonobstructive coronary artery disease (CAD). We aim to investigate the incremental prognostic value of PCATa beyond clinical and coronary computed tomographic angiography (CCTA) features in patients with nonobstructive CAD.

Methods: Consecutive patients with chest pain suspected of CAD referred for CCTA from January 2017 to December 2018 were prospectively included.

Research on Melamine-Urea-Formaldehyde/Nano-AlO Composite Foam Thermal Insulation Sealing Materials for Coal Mines.

In this study, melamine-urea-formaldehyde/nano-AlO (MUF/nano-AlO) composite gel foams were produced by foaming with CO generated by CaCO and phosphoric acid. Nano-AlO was introduced to the MUF matrix based on the optimum formulation obtained by the response surface methodology based on Box-Behnken design, and the effects of nano-AlO on the cell structure, apparent density, compressive strength, pulverization ratio, thermal stability, and thermal conductivity were investigated. The results revealed that the introduction of nano-AlO could improve the foaming and mechanical properties of MUF with smaller cell sizes, a narrower cell size distribution, decreased apparent density, higher compressive strength, and a decreased pulverization ratio.
