Efficient Photopolymerization of Dental Resin Composites Using the Photoluminescent Long Afterglow of SrMgSiO:Eu,Dy.

Dental curing light with blue emission acts as the excitation source for the photopolymerization of the dental composite resin to achieve dental repairing. However, the current repair methods still suffer from a low monomer conversion degree and incomplete resin curing. In this study, novel dental resin composites (DRCs) were prepared by combining SrMgSiO:Eu,Dy (SMSED), a photoluminescent material with a blue long afterglow, and dental resin composites.

Could Be a Potential Marker for Diagnosis and Prognosis in Glioma.

(1) Background: Glioma is among the most common brain tumors, and is difficult to eradicate with current therapeutic strategies due to its highly invasive and aggressive characteristics. Sestrin2 () is an autophagy inducer. The effect of on glioma is controversial and unclear.

Obstructive sleep apnea and serum total testosterone: a system review and meta-analysis.

Purpose: Testosterone deficiency (TD) negatively affects male sexuality, reproduction, general health, and quality of life. In recent years, decreased serum testosterone levels have been reported to be caused by obstructive sleep apnea (OSA). However, these results are controversial and lack the support of a large number of high-quality studies.

Fat mass and obesity-associated protein regulates RNA methylation associated with depression-like behavior in mice.

Post-transcriptional modifications of RNA, such as RNA methylation, can epigenetically regulate behavior, for instance learning and memory. However, it is unclear whether RNA methylation plays a critical role in the pathophysiology of major depression disorder (MDD). Here, we report that expression of the fat mass and obesity associated gene (FTO), an RNA demethylase, is downregulated in the hippocampus of patients with MDD and mouse models of depression.

[Effect of orthodontic traction on the microstructure of dental enamel].

Objective: To investigate the effect of orthodontic traction on the microstructure of dental enamel.

Methods: Forty-eight isolated premolars were randomly divided into 6 groups (=8), including Group A (blank control group), in which the teeth were bonded with the orthodontic brackets without any loading force; Groups B1, B2, and B3 where the teeth were bonded with the orthodontic brackets using clinical adhesives and loaded with 50 g force for 6 months, 200 g force for 6 months, and 200 g force for 1 month, respectively; and Groups C1 and C2, where the teeth were bonded with straight wire brackets using light curing bonding and chemical curing bonding techniques, respectively. All the teeth were embedded with non-decalcified epoxy resin.

Developmental validation of a novel six-dye typing system with 47 A-InDels and 2 Y-InDels.

In this study, a multiplex amplification system including 47 autosomal InDels, 2 Y-chromosome InDels, and the sex-determining marker (Amelogenin) was developed with six fluorescent dyes labeling. These InDels were selected from the previous study based on a series of criteria (0.3 < MAF < 0.
