[Effect of different cleaning methods on bond strength and surface wettability of high translucency zirconia].

Purpose: To study the effect of different cleaning methods on the shear bond strength of self-adhesive resin cement to saliva-contaminated high translucency zirconia and surface wettability.

Methods: Eighty zirconia specimens were randomly divided into 5 groups (n=16), i.e.

Spontaneous Symmetry Breaking of Achiral Molecules Leading to the Formation of Homochiral Superstructures that Exhibit Mechanoluminescence.

Chirality, with its intrinsic symmetry-breaking feature, is frequently utilized in the creation of acentric crystalline functional materials that exhibit intriguing optoelectronic properties. On the other hand, the development of chiral crystals from achiral molecules offers a solution that bypasses the need for enantiopure motifs, presenting a promising alternative and thereby expanding the possibilities of the self-assembly toolkit. Nevertheless, the rational design of achiral molecules that prefer spontaneous symmetry breaking during crystallization has so far been obscure.

Effects of cold atmospheric plasma treatment on resin bonding to high-translucency zirconia ceramics.

This study aims to evaluate the effects of cold atmospheric plasma (CAP) treatment on the bonding of resin cement to high-translucency zirconia. Zirconia specimens were subjected to different treatments: no treatment (ZrT), 10-methacryloyloxydecyl dihydrogen phosphate (MDP)-containing primer (ZrT-M), alumina particle air-abrasion with/without MDP-containing primer (ZrT-AM/ZrT-A), CAP with/without MDP-containing primer (ZrT-PM/ZrT-P). The surface topography, wettability, and chemical composition were evaluated.

Divergence among rice cultivars reveals roles for transposition and epimutation in ongoing evolution of genomic imprinting.

Parent-of-origin-dependent gene expression in mammals and flowering plants results from differing chromatin imprints (genomic imprinting) between maternally and paternally inherited alleles. Imprinted gene expression in the endosperm of seeds is associated with localized hypomethylation of maternally but not paternally inherited DNA, with certain small RNAs also displaying parent-of-origin-specific expression. To understand the evolution of imprinting mechanisms in (rice), we analyzed imprinting divergence among four cultivars that span both and subspecies: Nipponbare, Kitaake, 93-11, and IR64.

The research progress on the association between dietary habits and esophageal cancer: a narrative review.

Objective: This article summarizes the research progress on the association of dietary habits with esophageal cancer (EC), with the aim of gaining a better understanding of lifestyle, dietary, and drug-related risk factors as well as protective factors of EC.

Background: EC is one of the most common malignant cancers and has a high mortality rate. Evidence has suggested that dietary habits are closely related to EC.

Design, synthesis and bioactivity study on 5-phenylfuran derivatives as potent reversal agents against P-glycoprotein-mediated multidrug resistance in MCF-7/ADR cell.

P-glycoprotein (P-gp)-mediated multidrug resistance (MDR) is a phenomenon in which cells become resistant to structurally and mechanistically unrelated drugs resulting in low intracellular drug concentrations. It is one of the noteworthy problems in malignant tumor clinical therapeutics. So P-gp protein is one of the ideal targets to solve MDR.

A novel nest hybridization chain reaction based electrochemical assay for sensitive detection of circulating tumor DNA.

As an ideal biomarker candidate, circulating tumor DNA (ctDNA) plays a vital role in noninvasive diagnosis of cancer. However, most traditional approaches for quantifying ctDNA are cumbersome and expensive. In the present work, a novel electrochemical biosensor based on nest hybridization chain reaction was proposed for the sensitive and specific detection of PIK3CA E545K ctDNA with a simple process.

In situ effect of Tooth Mousse containing CPP-ACP on human enamel subjected to in vivo acid attacks.

Objective: This in situ study aimed to evaluate the protective effect of Tooth Mousse (GC) containing casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) on human enamel erosion and to compare the difference in erosion between the anteriorly and posteriorly positioned human enamel.

Methods: This study used a 2-treatment (7 days each) crossover design with 12 healthy volunteers wearing intraoral appliances. Each appliance contained 4 human enamel specimens positioned on the buccal surfaces of the volunteers' maxillary central incisors and first molars.
