Effect of modified investment and casting system on the recasting properties of high-gold alloy.

Background/purpose: High gold (Au) alloys have many advantages, such as good mechanical properties and stable chemical properties for dental restoration. The purpose of this investigation was to investigate the effect of zirconia (ZrO)-magnesia (MgO)-based investment combined with an argon arc vacuum pressure (Ar-arc VP) casting process on the recasting of high Au alloys.

Materials And Methods: The recasting Au alloys were compared between the control group of conventional SiO-based investment/horizontal centrifugal (HC) casting and the experimental group of ZrO-MgO-based investment/Ar-arc VP die casting.

Implant position accuracy using dynamic computer-assisted implant surgery (CAIS) combined with augmented reality: A randomized controlled clinical trial.

Background/purpose: Computer-assisted implant surgery (CAIS) is increasingly performed to reduce deviations in implant position. Dynamic CAIS or navigation systems provide instant display of implant drilling instruments and patient positions directly on the computer monitor. Augmented reality (AR) technology allows operators to visualize real-time information projected onto the lenses of AR glasses.

Achieving new excellence in an augmented reality dental education system.

Background/purpose: SimEx-Plus (EPED. Inc) was already a mature augmented reality (AR) dental training simulator that allowed students to have a high quality dental education practice. Now the EPCAD software has been further developed into a comprehensive computer-aided design software.

CRISPR/Cas9-mediated mutation provides a new insight into resveratrol biosynthesis by causing a metabolic pathway shift from flavonoids to stilbenoids in cells.

Resveratrol is an important phytoalexin that adapts to and responds to stressful conditions and plays various roles in health and medical therapies. However, it is only found in a limited number of plant species in low concentrations, which hinders its development and utilization. Chalcone synthase (CHS) and stilbene synthase (STS) catalyze the same substrates to produce flavonoids and resveratrol, respectively.

Diarrheagenic Outbreak Reporting to Foodborne Disease Outbreaks Surveillance System - China, 2011-2022.

What Is Already Known About This Topic?: Foodborne diarrheagenic (DEC) outbreaks constitute a significant global public health concern, yet comprehensive data on outbreak incidence and epidemiological characteristics in China remain limited.

What Is Added By This Report?: Between 2011 and 2022, there were 413 foodborne DEC outbreaks reported to foodborne disease outbreak surveillance system, resulting in 8,127 illnesses, 2,565 hospitalizations, and one fatality. Enteroaggregative (EAEC) emerged as the predominant causative pathogen (48.
