Purpose: This study aims to investigate the relationship between epicardial adipose tissue (EAT) and left atrial function in patients with preserved ejection fraction heart failure (HFpEF).

Methods: We conducted a cross-sectional study involving 113 patients diagnosed with HFpEF and 48 control subjects without heart failure. Echocardiography was performed to assess EAT thickness and left atrial function was quantified using Autostrain left atrium (LA), including left atrial strain during reservoir phase (LASr), left atrial strain during conduit phase (LAScd), and left atrial strain during contraction phase (LASct).

Article Synopsis
  • Renal cell carcinoma (RCC) is primarily treated through surgical options like radical or partial nephrectomy, and treatment decisions are based on histological classifications and the RENAL score, with contrast-enhanced ultrasound (CEUS) being a safer alternative to traditional imaging methods.
  • A retrospective study at Lanzhou University Second Hospital evaluated how CEUS can help in preoperatively assessing RCC histological classifications and RENAL scores by analyzing tumor features in 248 patients undergoing surgery.
  • Findings revealed that certain imaging features (hyperenhancement, heterogeneous enhancement, etc.) were significant indicators of clear cell RCC (ccRCC), suggesting CEUS has diagnostic efficacy comparable to contrast-enhanced CT in differentiating between cc

Background: The progression of triple-negative breast cancer is shaped by both tumor cells and the surrounding tumor microenvironment (TME). Within the TME, tumor-associated macrophages (TAMs) represent a significant cell population and have emerged as a primary target for cancer therapy. As antigen-presenting cells within the innate immune system, macrophages are pivotal in tumor immunotherapy through their phagocytic functions.

Article Synopsis
  • - Thymoma is a rare tumor in the chest area that can behave like a cancer, often spreading to the lungs, pleura (lining of the chest cavity), and mediastinum (space between the lungs).
  • - Cases of thymoma spreading to both intrathoracic (inside the chest) and extrathoracic (outside the chest) areas are extremely rare.
  • - This report highlights a unique case of invasive thymoma with multiple metastases and emphasizes the importance of using various imaging techniques for accurate diagnosis and treatment planning.

Lung cancer has emerged as the second most common type of malignant tumor worldwide, and it has the highest mortality rate. The overall 5-year survival rate stands at less than 20%, which is primarily related to the limited therapeutic options and the complexity of the tumor immune microenvironment. In the tumor microenvironment, M1 macrophages are known for their tumor-killing capabilities.

Article Synopsis
  • The immunosuppressive tumor microenvironment (TME) limits the effectiveness of immunotherapy, particularly in non-small cell lung cancer (NSCLC), where M2 tumor-associated macrophages (TAMs) play a key role in suppressing immune responses.
  • Researchers developed a novel ultrasound-responsive delivery system for siRNA targeting SIRPα to improve macrophage function and enhance immune responses against tumors.
  • The combined use of this delivery system with ultrasound significantly promotes T cell activity, increases immune cell infiltration, and inhibits tumor growth in NSCLC, suggesting a promising approach for cancer treatment.

M2-like tumor-associated macrophages (M2-TAMs) are closely correlated with metastasis and poor clinical outcomes in lung squamous cell carcinoma (LUSC). Previous studies have demonstrated that STAT6 is an important signaling molecule involved in the polarization of M2-TAMs, EMT is the main way for TAMs to promote tumor progression. However, little attention has been paid to the effect of STAT6 inhibition on LUSC, and it is difficult to achieve an ideal gene silencing effect in immune cells using traditional gene transfection methods.

Background: Microcirculatory perfusion disorder and inflammatory response are critical links in acute kidney injury (AKI). We aim to construct anti-vascular cell adhesion molecule-1(VCAM-1) targeted microbubbles (TM) to monitor renal microcirculatory perfusion and inflammatory response.

Methods: TM carrying VCAM-1 polypeptide was constructed by biological coupling.

This study investigates the impact of Photobiomodulation (PBM) at different wavelengths on non-superficial cancer cells. Utilizing three laser protocols (650 nm, 810 nm, and 915 nm), the research explores cytotoxic effects, ROS generation, and cell migration. Results reveal varied responses across cell lines, with 810 nm PBM inducing significant ROS levels and inhibiting PAN-1 cell migration.

Objective: To investigate the diagnostic value of CEUS in atypical-enhanced PTC.

Methods: The clinical data, qualitative and quantitative parameters of CEUS in 177 Iso/hyper-enhanced thyroid nodules with definite pathological results were retrospectively analyzed in the Lanzhou University Second Hospital from June 2019 to January 2021. And the clinical value of CEUS in the diagnosis of atypical-enhanced PTC was assessed using univariate and multivariate analysis.

Objective: To evaluate the effectiveness of conventional US (ultrasound), SMI (superb microvascular imaging), and CEUS (contrast-enhanced ultrasound) features for the assessment of the activity of inflammatory bowel disease.

Methods: Conventional US, CEUS and SMI features of 76 patients were retrospectively analyzed. Patients were categorized into two groups: active group (n = 57) and inactive group (n = 19), with endoscopic results as reference standard.

Background: A prenatal fetal mediastinal cyst is a benign disease. However, if a cyst enlargement grows, it may compress the adjacent organs and affect the fetal cardiopulmonary function. This study aimed to compare and analyze the prenatal ultrasound characteristics of different mediastinal cysts, and to evaluate the pregnancy outcome of the fetus and the factors affecting the prognostic of the fetus.

The engineering of ferroic orders, which involves the evolution of atomic structure and local ferroic configuration in the development of next-generation electronic devices. Until now, diverse polarization structures and topological domains are obtained in ferroelectric thin films or heterostructures, and the polarization switching and subsequent domain nucleation are found to be more conducive to building energy-efficient and multifunctional polarization structures. In this work, a continuous and periodic strain in a flexible freestanding BaTiO membrane to achieve a zigzag morphology is introduced.

Background: Although imaging techniques provide information about the morphology and stability of carotid plaque, they are operator dependent and may miss certain subtleties. A variety of radiomics models for carotid plaque have recently been proposed for identifying vulnerable plaques and predicting cardiovascular and cerebrovascular diseases. The purpose of this review was to assess the risk of bias, reporting, and methodological quality of radiomics models for carotid atherosclerosis plaques.
