Factors influencing preformed metal crowns and prefabricated zirconia crowns.

Backgound: Preformed metal crowns (PMCs) and zirconia crowns (ZCs) are commonly used for the treatment of primary molar caries. However, there have been no reports on factors influencing parental awareness, willingness to use these treatments, and the associated discomfort after crown placement in children.This study is the first to report factors influencing preformed crowns, providing a reference for the prevention and treatment of deciduous carious teeth.

In situ structural-functional synchronous dissection of dynamic neuromuscular system via an integrated multimodal wearable patch.

Neuromuscular abnormality is the leading cause of disability in adults. Understanding the complex interplay between muscle structure and function is crucial for effective treatment and rehabilitation. However, the substantial deformation of muscles during movement (up to 40%) poses challenges for accurate assessment.

However, the dynamic alterations of the vaginal microbiome in pregnant women with VVC and its effect on neonatal gut microbiome remain unclear. This study aims to characterize the vaginal microbiome in pregnant women with VVC and its impact on their offspring's meconium microbiome.

[Clinical characteristics of cytokine release syndrome after haploidentical hematopoietic stem cell transplantation for thalassemia major].

Objectives: To investigate the clinical characteristics of cytokine release syndrome (CRS) in children with thalassemia major (TM) after haploidentical hematopoietic stem cell transplantation (haplo-HSCT) and their prognosis.

Methods: A retrospective analysis was performed for the clinical data of 280 children with TM who underwent haplo-HSCT in the Department of Hematology and Oncology, Shenzhen Children's Hospital, from January 2019 to December 2021. According to the CRS criteria, they were divided into two groups: CRS grade <3 (260 children) and CRS grade ≥3 (20 children).

Artificial intelligence-assisted echocardiographic monitoring in pediatric patients on extracorporeal membrane oxygenation.

Background: Percutaneous extracorporeal membrane oxygenation (ECMO) is administered to pediatric patients with cardiogenic shock or cardiac arrest. The traditional method uses focal echocardiography to complete the left ventricular measurement. However, echocardiographic determination of the ejection fraction (EF) by manual tracing of the endocardial borders is time consuming and operator dependent.

Discovery of the first examples of right open reading frame kinase 2 (RIOK2) molecular glue degraders.

Right open reading frame kinase 2 (RIOK2) is an atypical serine threonine kinase which plays an important role in regulating ribosome synthesis and cell cycle progression. RIOK2 has been implicated in multiple human cancers and is a potential target for cancer treatment. We previously reported the discovery of CQ211 as a potent and selective RIOK2 inhibitor.

Carboxymethyl Chitosan-Based Antioxidant Hydrogel Accelerates Diabetic Wound Healing.

Diabetic wound healing is hampered due to oxidative stress, exacerbated inflammation, and impaired angiogenesis in the wounds. A pH-sensitive antioxidant hydrogel based on carboxymethyl chitosan (CMCS), oligoprocyanidins (OPC), and oxide dextran (Oxd) is prepared to accelerate diabetic wound healing. The hydrogel network is formed via imine and hydrogen bonding interactions in the presence of hydroxyl, amino, and aldehyde groups, and deferoxamine (DFO) is incorporated into the hydrogel.

A cross-linked coating loaded with antimicrobial peptides for corrosion control, early antibacterial, and sequential osteogenic promotion on a magnesium alloy as orthopedic implants.

Magnesium (Mg)-based alloys have been recognized as desirable biodegradable materials for orthopedic implants. However, their clinical application has been limited by rapid degradation rates, insufficient antibacterial and osteogenic-promotion properties. Herein, a MgF priming layer was first constructed on AZ31 surface.

Melodinines J Induces Apoptosis in Temozolomide-Resistant Glioma Cells by Disrupting TMX1-Dependent Homeostasis of Endoplasmic Reticulum-Mitochondria-Associated Membrane Contacts.

Glioma is recognized as one of the most lethal and aggressive brain tumors. Although the standard-of-care treatment for glioblastoma (GBM) involves maximal surgical resection and temozolomide (TMZ) chemotherapy, the discovery of novel anti-tumor agents from nature sources is an effective strategy for glioma treatment. In this study, we conducted a screening process to identify the bisindole alkaloid melodinine J (MDJ) from Melodinus tenuicaudatus.

Computer-Aided High Tibial Osteotomy-A Comparative Study of Commonly Used 3D Printing Technology and Navigation Application.

Hierarchically Porous Microgels with Interior Spiral Canals for High-Efficiency Delivery of Stem Cells in Wound Healing.

Chronic wound poses a serious risk to diabetic patients, primarily due to damaged skin microvasculature and prolonged inflammation at the wound site. Mesenchymal stem cell (MSC) therapy utilizing microgels as a cell delivery system has shown promise in promoting wound healing by enhancing cell viability and the secretion of bioactive factors. Retaining sufficient MSCs at injury sites is crucial for optimal therapeutic outcomes.

Detection of circulating tumor cells using a microfluidic chip for diagnostics and therapeutic prediction in mediastinal neuroblastoma.

Circulating tumor cells (CTCs) have served as noninvasive tumor biomarkers in many types of cancer. Here, we detected CTCs in mediastinal neuroblastoma (mNB) patients for use as diagnostic and treatment response predictive biomarkers. We employed a cascaded filter deterministic lateral displacement microfluidic chip (CFD-Chip) to enrich CTCs in peripheral blood from 32 mNB patients and 7 healthy children.

Etiology and clinical features of children with bronchiectasis-Insight from Chinese experience.

Bronchiectasis is a clinical syndrome characterized by cough, sputum production, and the presence of abnormal thickening and dilation of the bronchial wall on imaging. There has been a remarkable resurgence in incidence and prevalence during the past 20 years. There was few data from children.

Engineered virus-mimicking nanovaccine with lymph node-tumor dual-targeting and STING-activating capacity for robust cancer immunotherapy.

Cancer vaccines have garnered considerable interest for cancer immunotherapy. However, their effectiveness is limited by inadequate proliferation, activation, and tumor infiltration of cytotoxic T lymphocytes (CTLs). Inspired by the potent immunostimulatory properties of viral components and the exposure of calreticulin during immunogenic cell death (ICD) triggered by viral infections; in this study, we describe cGAMP@vEVs, a virus-mimicking nanovaccine strategy by engineering tumor cell-derived extracellular vesicles through virus infection, which co-load both personalized and broad antigen repertoire as well as multiple immune adjuvants to potently elicit antitumor immunity.
