Existing techniques for pacing the right ventricle and providing cardiac resynchronization therapy through biventricular pacing are not effective in restoring damage to the conduction system. Therefore, the need for new pacing modalities and techniques with more sensible designs and algorithms is justified. Although the benefits of conduction system pacing (CSP), which mainly include His bundle pacing (HBP) and left bundle branch area pacing (LBBAP), are evident in patients who require conduction system recuperation, the critical criteria for left CSP remain unclear, and the roles of different pacing modalities of CSP for cardiac resynchronization are not definite.

Introduction: Effective postoperative pain management remains a significant challenge due to the severe side effects of opioids and the limitations of existing analgesic delivery systems. Inflammation plays a critical role in pain exacerbation, highlighting the need for therapies that combine analgesic effects with intrinsic anti-inflammatory properties.

Methods: Herein, we develop an intrinsic anti-inflammatory nanomedicine designed to enhance pain management by integrating controlled anesthetic release with inherent anti-inflammatory activity.

Current understanding of articular cartilage lesions in femoroacetabular impingement syndrome.

J Orthop Surg Res

December 2024

Department of Joint and Sports Medicine, The First Affiliated Hospital of Dalian Medical University, No.193 Lianhe Road, Shahekou District, Dalian, 116021, China.

The concept of femoroacetabular impingement syndrome (FAIS) has received much attention over the past 20 years. Currently, it is believed that FAIS can lead to intra-articular pathologies such as labral tears and articular cartilage lesions, resulting in clinical symptoms and subsequent poor clinical outcomes. FAIS-related articular cartilage lesions are common but unique, and their natural course always leads to early osteoarthritis of the hip.

Our study aimed to investigate the relationship between δ-catenin expression and whole-brain small-world network in breast cancer patients before chemotherapy using rs-fMRI. The study was based on the hypothesis that different δ-catenin expression levels correspond to distinct brain imaging characteristics. A total of 105 pathologically confirmed breast cancer patients were collected and categorized into high δ-catenin expression (DH, 52 cases) and low expression (DL, 53 cases) groups.

Based on the systematic review of literatures related to ultrasound-guided thermal ablation of thyroid nodules and the professional opinions of experts, the guidelines define the indications and contraindications of thermal ablation, including pre-ablation evaluation and preparation, thermal ablation techniques and operational procedures, post-ablation follow-up, therapeutic effect evaluation, complications prevention and treatment, and the writing of medical documents for ablation. According to the Grading of Recommendations Assessment, Development and Evaluation (GRADE), a total of 17 objective and comprehensive recommendations were given.

Purpose: To explore the value of quantitative imaging parameters by enhanced T weighted angiography (ESWAN) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) for evaluating the expression of Hypoxia-inducible factor-1α (HIF-1α) in endometrial carcinoma (EC).

Methods: Data from 122 patients with EC confirmed by clinical pathology were retrospectively analyzed. According to the number of positive cells stained with HIF-1α by immunohistochemistry, patients were divided into two groups: 65 cases with high expression of HIF-1α and 57 cases with low expression of HIF-1α.

Inflammatory bowel disease (IBD) is a chronic inflammatory condition of the gastrointestinal tract. Sea conch peptide hydrolysate (CPH) was produced by enzymatic digestion of fresh conch meat with trypsin enzyme. To analyze the molecular composition, functional groups, and structural morphology of the hydrolysate, we employed liquid chromatography-mass spectrometry (LC-MS), Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM).

Up to half of hepatocellular carcinoma (HCC) cases are diagnosed at an advanced stage, for which effective treatment options are lacking, resulting in a poor prognosis. Over the past few years, the combination of immune checkpoint inhibitors and anti-angiogenic targeted therapy has proven highly efficacious in treating advanced HCC, significantly extending patients' survival and providing a potential for sequential curative surgery. After sequential curative hepatectomy or liver transplantation following conversion therapy, patients can receive long-term survival benefits.

Background And Purpose: Esophageal and gastric varices hemorrhage (EGVH) is a life-threatening condition with the 6-week mortality rate of 15-25%. Up to 60% of patients with EGVH may experience rebleeding with a mortality rate of 33%. The existing scoring systems, such as RS scoring system (Rockall score, RS) and GBS scoring system (Glasgow-Blatchford score, GBS), have limitations in predicting the risk of rebleeding.

Cardiac remodeling encompasses structural alterations such as hypertrophy, fibrosis, and dilatation, alongside numerous cellular and molecular functional aberrations, constituting a pivotal process in the advancement of heart failure (HF). 4-Hydroxychalcone (4-HCH) is a class of naturally occurring compounds with variable phenolic structures, and has demonstrated the preventive efficacy in hyperaldosteronism, inflammation and renal injury. However, the role of 4-HCH in the regulation of cardiac remodeling remains uncertain.

Background: The typical pathological feature of pancreatic ductal adenocarcinoma (PDAC) is a significant increase in stromal reaction, leading to a hypoxic and poorly vascularized tumor microenvironment. Tumor cells undergo metabolic reprogramming, such as the Warburg effect, yet the underlying mechanisms are not fully understood.

Methods: Interference and overexpression experiments were conducted to analyze the in vivo and in vitro effects of USP7 on the growth and glycolysis of tumor cells.

A flexible, water anchoring, and colorimetric ionogel for sweat monitoring.

Biomater Sci

December 2024

Department of Instrumentation and Analytical Chemistry, CAS Key Laboratory of Separation Science for Analytical Chemistry, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, Dalian 116023, P. R. China.

As water-saturated polymer networks, the easy water loss of hydrogels directly affects their end-use applications. Minimizing the ratio of free water and increasing the ratio of bound water in the gel system has become key to extending the service life. In this work, an ionogel is prepared that effectively regulates the proportion of free water and bound water through the formation of wrinkle angles by the hydrophilic and hydrophobic chains in the gel system and the non-volatile nature of the ionic liquid.

Article Synopsis
  • MACC1 is a newly identified factor in lung cancer that promotes the transition of non-cancer stem cells (non-CSCs) to cancer stem cells (CSCs), which play a key role in tumor growth.
  • High levels of MACC1 are found in stemness-enriched lung cancer cells, and reducing MACC1 expression through shRNA effectively halts this transition.
  • The study suggests that MACC1 stabilizes KLF4 mRNA by inhibiting microRNA-25, and understanding this relationship could lead to targeted therapies for cancer stem cells.

Article Synopsis
  • This study investigates the effect of conduction system pacing (CSP) on the occurrence of atrial high-rate episodes (AHREs) in heart failure patients with preserved ejection fraction (HFpEF), comparing it to right ventricular pacing (RVP).
  • Researchers analyzed data from 498 patients who received dual-chamber pacemakers between January 2018 and January 2023, noting both new-onset and progressive AHREs.
  • Findings indicate that CSP is associated with a significantly lower incidence of new-onset AHREs in patients without prior atrial fibrillation compared to RVP, and also showed improvements in various cardiac performance metrics following CSP.

Bladder cancer (BCa) is a heterogeneous malignancy characterized by distinct immune subtypes, primarily due to differences in tumor-infiltrating immune cells and their functional characteristics. Therefore, understanding the tumor immune microenvironment (TIME) landscape in BCa is crucial for prognostic prediction and guiding precision therapy. In this study, we integrated 10 machine learning algorithms to develop an immune-related machine learning signature (IRMLS) and subsequently created a deep learning model to detect the IRMLS subtype based on pathological images.
