Identification of markers correlating with mitochondrial function in myocardial infarction by bioinformatics.

Background: Myocardial infarction (MI), one of the most serious cardiovascular diseases, is also affected by altered mitochondrial metabolism and immune status, but their crosstalk is poorly understood. In this paper, we use bioinformatics to explore key targets associated with mitochondrial metabolic function in MI.

Methods: The datasets (GSE775, GSE183272 and GSE236374) were from National Center for Biotechnology Information (NCBI) Gene Expression Omnibus (GEO) in conjunction with mitochondrial gene data that were downloaded from the MitoCarta 3.

The Roles of DMT1 in Inflammatory and Degenerative Diseases.

Iron homeostasis is critical for multiple physiological and pathological processes. DMT1, a core iron transporter, is expressed in almost all cells and organs and altered in response to various conditions, whereas, there is few reviews focusing on DMT1 in diseases associated with aberrant iron metabolism. Based on available knowledge, this review described a full view of DMT1 and summarized the roles of DMT1 and DMT1-mediated iron metabolism in the onset and development of inflammatory and degenerative diseases.

Microfluidics has emerged as one of the most popular platforms for performing liquid biopsy applications.

FDG PET/CT in a Case of Metastasizing Pleomorphic Adenoma in the Ilium.

Although pleomorphic adenomas of the salivary glands are benign tumors, they can metastasize to distant organs without evidence of malignant transformation. We describe FDG PET/CT finding in a case of metastasizing pleomorphic adenoma in the right ilium occurring 22 years after initial surgical resection of a lip pleomorphic adenoma. On FDG PET/CT, the iliac metastasis appeared as an expansile osteolytic lesion with heterogeneous activity.

Indication of frailty transitions on 2-year adverse health outcomes among older Chinese inpatients: Insight from a multicenter prospective cohort study.

Introduction: Frailty is thought to be associated with an increased risk of adverse health outcomes such as death and falls, but comparatively little is known about the impact of frailty transitions on the adverse health outcomes. Moreover, owing to insufficient sample size or a single-center study design, previous studies have not been sufficiently representative of elderly inpatients in China. This study aimed to provide estimates at the population level of the association between frailty transitions and adverse outcomes among elderly inpatients following discharge.

Effect analysis of radiofrequency catheter ablation in the treatment of 7 children with atrial tachycardia-induced cardiomyopathy.

Background: Tachycardia-induced cardiomyopathy refers to changes in cardiac structure and function that result from rapid arrhythmia and can manifest as a continuous or recurrent event. Cardiomyopathy induced by atrial tachycardia is typically reversible if the arrhythmia is effectively controlled. There are few literature reports of atrial tachycardia-induced cardiomyopathy in children, and fewer cases have been effectively treated by radiofrequency catheter ablation in children.

FOXC1-mediated serine metabolism reprogramming enhances colorectal cancer growth and 5-FU resistance under serine restriction.

Colorectal cancer (CRC) is the most common gastrointestinal malignancy, and 5-Fluorouracil (5-FU) is the principal chemotherapeutic drug used for its treatment. However, 5-FU resistance remains a significant challenge. Under stress conditions, tumor metabolic reprogramming influences 5-FU resistance.

Psychological stress disturbs bone metabolism via miR-335-3p/Fos signaling in osteoclast.

It has been well validated that chronic psychological stress leads to bone loss, but the underlying mechanism remains unclarified. In this study, we established and analyzed the chronic unpredictable mild stress (CUMS) mice to investigate the miRNA-related pathogenic mechanism involved in psychological stress-induced osteoporosis. Our result found that these CUMS mice exhibited osteoporosis phenotype that is mainly attributed to the abnormal activities of osteoclasts.

Pharmacokinetics, efficacy, and safety of subcutaneous versus intravenous rituximab in previously untreated Chinese patients with CD20+ diffuse large B-cell lymphoma: a phase II randomized controlled trial.

Subcutaneous (SC) rituximab has demonstrated advantages over intravenous (IV) administration; however, insufficient data exist on its use with cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in Chinese patients with diffuse large B-cell lymphoma (DLBCL). This multicenter, phase II, randomized, controlled study was conducted across China between February 2021 and October 2022. Fifty adult patients with previously untreated CD20-positive DLBCL were randomized to receive one cycle of IV rituximab and seven cycles of SC rituximab (R-CHOP;  = 26), or eight cycles of IV rituximab (R-CHOP;  = 24), combined with six or eight cycles of CHOP.

Three-dimensional nonreciprocal transport in photonic topological heterostructure of arbitrary shape.

Electromagnetic wave propagation in three-dimensional (3D) space typically suffers omnidirectional scattering when encountering obstacles. In this study, we used Chern vectors to construct a topological heterostructure, where large-volume nonreciprocal topological transport in 3D is achieved. The shape of the cross section in the heterostructure can be arbitrary designed, and we experimentally observed the distinctive cross-shaped field pattern transport, nonreciprocal energy harvesting, and the remarkable ability of electromagnetic wave to traverse obstacles and abrupt structure changes without encountering reflections in 3D space.

Tgfβ signaling stimulates glycolysis to promote the genesis of synovial joint interzone in developing mouse embryonic limbs.

The initial interzone cells for synovial joints originate from chondrocytes, but such critical transition is minimally understood. With single-cell RNA sequencing (scRNA-seq) of murine embryonic knee joint primordia, we discovered that heightened expression of glycolysis genes characterized developing interzone cells when compared to flanking chondrocytes. Conditional deletion of the glucose transporters and/or , in either the incipient pre-skeletal mesenchyme with or in chondrocytes with , disrupted interzone formation dose-dependently.
