Bifidobacterium animalis subsp. lactis A6 ameliorates bone and muscle loss via modulating gut microbiota composition and enhancing butyrate production.

Systematic bone and muscle loss is a complex metabolic disease, which is frequently linked to gut dysfunction, yet its etiology and treatment remain elusive. While probiotics show promise in managing diseases through microbiome modulation, their therapeutic impact on gut dysfunction-induced bone and muscle loss remains to be elucidated. Employing dextran sulfate sodium (DSS)-induced gut dysfunction model and wide-spectrum antibiotics (ABX)-treated mice model, our study revealed that gut dysfunction instigates muscle and bone loss, accompanied by microbial imbalances.

Evaluating the efficacy of the SENO decision framework in managing metastatic spinal disease: a comparative study.

Background Context: The management of metastatic spinal disease presents a complex challenge, with no universally accepted guidelines currently available. A new treatment approach, termed the "SENO" (Systemic Conditions, Effectiveness of Systemic Treatment, Neurology, and Oncology) decision framework, was developed, incorporating a 12-point grading system for epidural spinal cord compression.

Purpose: This study aims to assess the clinical efficacy of the SENO decision framework and compare its outcomes with those from traditional treatment frameworks.

Deciphering Immune Landscape Remodeling Unravels the Underlying Mechanism for Synchronized Muscle and Bone Aging.

Evidence from numerous studies has revealed the synchronous progression of aging in bone and muscle; however, little is known about the underlying mechanisms. To this end, human muscles and bones are harvested and the aging-associated transcriptional dynamics of two tissues in parallel using single-cell RNA sequencing are surveyed. A subset of lipid-associated macrophages (triggering receptor expressed on myeloid cells 2, TREM2 Macs) is identified in both aged muscle and bone.

Promoting postoperative recovery in patients with metastatic epidural spinal cord compression based on the concept of ERAS: a multicenter analysis of 304 patients.

Background Context: Enhanced recovery after surgery (ERAS) has proven beneficial for patients undergoing orthopedic surgery. However, the application of ERAS in the context of metastatic epidural spinal cord compression (MESCC) remains undefined.

Purpose: This study aims to establish a medical pathway rooted in the ERAS concept, with the ultimate goal of scrutinizing its efficacy in enhancing postoperative outcomes among patients suffering from MESCC.

A New Treatment Strategy for Spinal Metastasis: The "Systemic Conditions, Effectiveness of Systemic Treatment, Neurology, and Oncology" Decision Framework System.

Background And Objectives: Treating metastatic spinal tumors poses a significant challenge because there are currently no universally applied guidelines for managing spinal metastases. This study aims to propose a new decision framework for the 12-point epidural spinal cord compression grading system to treat patients with metastatic spinal tumors and investigate its clinical effectiveness in a multicenter analysis.

Methods: This study analyzed 940 patients with metastatic spinal tumors between December 2017 and March 2023.

Development of a novel 12-point grading system for evaluating epidural spinal cord compression and its clinical implications.

Background Context: The assessment of epidural spinal cord compression (ESCC) plays a crucial role in clinical decision-making, yet the current grading system lacks reliability and requires improvements.

Purpose: The study aims to develop a reliable grading system for evaluating ESCC and to investigate its association with the neurological status of patients.

Study Design/setting: A prospective cohort study.

Multi-Proteomic Analysis Reveals the Effect of Protein Lactylation on Matrix and Cholesterol Metabolism in Tendinopathy.

Tendinopathy is a disease with surging prevalence. Lacking understanding of molecular mechanisms impedes the development of therapeutic approaches and agents. Lysine lactylation (Kla) is a newly discovered post-translational modification related to glycolysis.

The antibacterial activity and mechanism of imidazole chloride ionic liquids on .

Ionic liquids (ILs) have garnered increasing attention in the biomedical field due to their unique properties. Although significant research has been conducted in recent years, there is still a lack of understanding of the potential applications of ILs in the biomedical field and the underlying principles. To identify the antibacterial activity and mechanism of ILs on bacteria, we evaluated the antimicrobial potency of imidazole chloride ILs (CMIMCl) on ().

Ghost messages: cell death signals spread.

Cell death is a mystery in various forms. Whichever type of cell death, this is always accompanied by active or passive molecules release. The recent years marked the renaissance of the study of these molecules showing they can signal to and communicate with recipient cells and regulate physio- or pathological events.

Preoperative embolization in the treatment of patients with metastatic epidural spinal cord compression: A retrospective analysis.

Purpose: The purpose of the study was to assess the effectiveness and safety of preoperative embolization in the treatment of patients with metastatic epidural spinal cord compression (MESCC).

Methods: A retrospective analysis of 138 MESCC patients who underwent decompressive surgery and spine stabilization was performed in a large teaching hospital. Among all enrolled patients, 46 patients were treated with preoperative embolization (the embolization group), whereas 92 patients did not (the control group).

Mechanisms of estrogen deficiency-induced osteoporosis based on transcriptome and DNA methylation.

Osteoporosis is a disease that impacts the elderly. Low estrogen is related to changes in DNA methylation and consequent alterations in gene expression, leading to a new direction in research related to the pathophysiology of osteoporosis. We constructed an Ovariectomized (OVX) mouse model in our study, and the mouse models had osteoporosis based on the phenotype and methylation levels in the mouse's bone.

Bioinspired Polysaccharide-Derived Zwitterionic Brush-like Copolymer as an Injectable Biolubricant for Arthritis Treatment.

Developing highly efficient and biocompatible biolubricants for arthritis treatment is extraordinarily demanded. Herein, inspired by the efficient lubrication of synovial joints, a paradigm that combines natural polysaccharide (chitosan) with zwitterionic poly[2-(methacryloyloxy) ethyl phosphorylcholine] (PMPC), to design a series of brush-like Chitosan-g-PMPC copolymers with highly efficient biological lubrication and good biocompatibility is presented. The Chitosan-g-PMPC copolymers are prepared via facile one-step graft polymerization in aqueous medium without using any toxic catalysts and organic solvents.
