Storage environment caused the difference between Jinhua Pu-erh tea (JPT) and General Pu-erh tea. In this study, fungal flora and chemical compositions were analyzed. The results showed that storage environment caused significant ( < .05) differences of theaflavins (TF), theabrownins (TB), tea polyphenols (TP), and water-soluble sugars (WSS), and a highly significant ( < .01) difference of thearubigins (TR). , , , and were isolated from Pu-erh teas and identified based on colony characteristics and ITS, β-tubulin, and calmodulin gene sequences, respectively. , , and were dominant fungi in JPT and generated macroscopic yellow cleistothecia after a long-term storage. Correlation analysis showed that dominant fungi exhibited significantly ( < .05 or < .01) positive or negative corrections with TF, TB, TP, WSS, TR, and gallic acid. This study revealed dominant fungi including , and and their effects on given chemical compositions.

Effect of modified investment and casting system on the recasting properties of high-gold alloy.
J Dent Sci
December 2024
School of Dentistry, College of Dental Medicine, Kaohsiung Medical University, Kaohsiung, Taiwan.
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.
Updates on the clinical application of glass ionomer cement in restorative and preventive dentistry.
J Dent Sci
December 2024
Faculty of Dentistry, The University of Hong Kong, Hong Kong, S.A.R., China.
The World Health Organization (WHO) has added glass ionomer cement (GIC) to the WHO Model List of Essential Medicines since 2021, which represents the most efficacious, safe and cost-effective medicines for priority conditions. With the potential increase in the use of GIC, this review aims to provide an overview of the clinical application of GIC with updated evidence in restorative and preventive dentistry. GIC is a versatile dental material that has a wide range of clinical applications, particularly in restorative and preventive dentistry.

Unlabelled: Integrated Assessment Models (IAMs) and System Dynamic Models (SDMs) are starting to incorporate representations of the impact of environmental changes on health and socio-economic development into their modelling frameworks. We use this brief review to provide an overview of how health and well-being are currently represented in IAMs and SDMs. A grey literature search on 12 selected model host websites and their corresponding Wiki pages was conducted.

Thermoplastic polymers provide a versatile platform to mimic various aspects of physiological extracellular matrix properties such as chemical composition, stiffness, and topography for use in cell and tissue engineering applications. In this review, we provide a brief overview of the most promising thermoplastic polymers, and in particular the thermoplastic polyesters, such as poly(lactic acid), poly(glycolic acid), and polycaprolactone, and the thermoplastic elastomers, such as polyurethanes, polyhydroxyalkanoates, and poly(butyl cyanoacrylate). A particular focus has been made on the synthesis processes, the processability and the biocompatibility.
