Effect of different techniques on removal of residual resin cement and marginal roughness of porcelain laminate veneers.

Statement Of Problem: A consensus regarding how to effectively remove residual resin cement and polish the restoration margin during the cementation of porcelain laminate veneers (PLVs) is lacking.

Purpose: The purpose of this in vitro study was to evaluate the effect of different cleaning and polishing techniques on the removal of residual resin cement and margin surface roughness of PLVs.

Material And Methods: PLVs were bonded to prepared buccal surfaces of extracted human premolars.

Generation of a human embryonic stem cell line (SMUDHe010-A-1A) carrying Brainbow cassette in the AAVS1 gene by CRISPR/Cas9-mediated homologous recombination.

Tracking single-cell lineages and their phenotypes longitudinally would help us better study skin development. Brainbow multicolor labeling approach is a genetic cell-labeling technique that tracks individual cells or analyzes cell lineages during development. Hence, we generated a stable Cre-inducible rainbow reporter human embryonic stem cell line (Named SMUDHe010-A-1A) by inserting the fluorescent protein gene (nGFP, YFP, RFP and CFP) at AAVS1 safe harbor locus using CRISPR/Cas9 technology.

Generation of a human embryonic stem cell line (SMUDHe010-A-1B) carrying inducible DTA expression cassette in the AAVS1 locus by CRISPR/Cas9-mediated homologous recombination.

Diphtheria toxin A (DTA) is an exotoxin secreted by Corynebacterium diphtheriae. After entering the cell through receptor-mediated manner, DTA can trigger the programmed cell death mechanism and lead to cell death. In 2001, Michiko Saito established a Diphtheria toxin receptor-mediated cell knockout system, which can conditional deplete specific cell type in transgenic mice.

Establishment of a Selective Liver Lobe Tumor-Bearing Mouse Model of Colorectal Cancer.

Purpose: Colorectal cancer is one of the most common causes of cancer-related death, and its main site of metastasis is the liver. The surgical method used for metastases of colorectal cancer in the liver varies according to the lobe affected, as does the prognosis. However, there is a lack of relevant basic research.

AHNAK, regulated by the OSM/OSMR signaling, involved in the development of primary localized cutaneous amyloidosis.

Background: Primary localized cutaneous amyloidosis (PLCA) is a chronic skin disease characterized by aberrant keratinocyte differentiation, epidermal hyperproliferation, and amyloid deposits. Previously, we demonstrated OSMR loss-function mutants enhanced basal keratinocyte differentiation through the OSMR/STAT5/KLF7 signaling in PLCA patients.

Objective: To investigate the underlying mechanisms involved in basal keratinocyte proliferation in PLCA patients that remain unclear.

Transmembrane water-efflux rate measured by magnetic resonance imaging as a biomarker of the expression of aquaporin-4 in gliomas.

The water-selective channel protein aquaporin-4 (AQP4) contributes to the migration and proliferation of gliomas, and to their resistance to therapy. Here we show, in glioma cell cultures, in subcutaneous and orthotopic gliomas in rats, and in glioma tumours in patients, that transmembrane water-efflux rate is a sensitive biomarker of AQP4 expression and can be measured via conventional dynamic-contrast-enhanced magnetic resonance imaging. Water-efflux rates correlated with stages of glioma proliferation as well as with changes in the heterogeneity of intra-tumoural and inter-tumoural AQP4 in rodent and human gliomas following treatment with temozolomide and with the AQP4 inhibitor TGN020.

Color change of glass ceramic restorations cemented by four types of dual-cured resin luting agents with different initiator systems.

This study aimed to comprehensively evaluate the effect of dual-cured resin luting agents with different initiator systems on the color stability of glass ceramic restorations by simulating various clinical glass ceramic restorations. Three commonly used shades from each of the two dual-cured resin luting agents with an amine-initiation system or without it were studied. The individual specimens had different translucency and thickness and were artificially aged using a xenon light aging machine.

Generation of a human embryonic stem cell line (SMUDHe010-A-82) carrying a homozygous c.1538G > A (p.G513D) mutation in the OSMR gene by CRISPR/Cas9-mediated homologous recombination.

Mutations in the tumor suppressor M receptor (OSMR) gene are associated with primary localized cutaneous amyloidosis (PLCA). Recently, we confirmed that OSMR loss-of-function mutations enhance epidermal keratinocyte differentiation via inactivation of the STAT5/KLF7 signaling. However, no disease model was available for PLCA.

Olfactory sensory experience regulates gliomagenesis via neuronal IGF1.

Animals constantly receive various sensory stimuli, such as odours, sounds, light and touch, from the surrounding environment. These sensory inputs are essential for animals to search for food and avoid predators, but they also affect their physiological status, and may cause diseases such as cancer. Malignant gliomas-the most lethal form of brain tumour-are known to intimately communicate with neurons at the cellular level.

Oncogenic State and Cell Identity Combinatorially Dictate the Susceptibility of Cells within Glioma Development Hierarchy to IGF1R Targeting.

Glioblastoma is the most malignant cancer in the brain and currently incurable. It is urgent to identify effective targets for this lethal disease. Inhibition of such targets should suppress the growth of cancer cells and, ideally also precancerous cells for early prevention, but minimally affect their normal counterparts.
