The use of cardiopulmonary bypass, deep hypothermia and circulatory arrest has decreased the risks of hemorrhage, tumor embolization, incomplete thrombus resection, and warm hepatic and renal ischemia associated with resection of renal cell carcinoma extending into the inferior vena cava above the hepatic veins. Patients about to undergo this operation frequently have significant coronary artery and carotid artery disease, and are at risk for perioperative myocardial infarction and stroke. Preoperative evaluation of the coronary artery and carotid artery circulation by coronary angiography, duplex carotid artery scan and digital subtraction carotid angiography is recommended. Depending upon the severity and location of the cardiovascular disease a sequential or simultaneous operation may be performed. This surgical approach can be used in selected patients to facilitate complete tumor thrombectomy with a low operative risk.

Introduction: The core objective of this study was to precisely locate metastatic lymph nodes, identify potential areas in nasopharyngeal carcinoma patients that may not require radiotherapy, and propose a hypothesis for reduced target volume radiotherapy on the basis of these findings. Ultimately, we reassessed the differences in dosimetry of organs at risk (OARs) between reduced target volume (reduced CTV2) radiotherapy and standard radiotherapy.
Methods And Materials: A total of 209 patients participated in the study.

Purpose: Pituitary adenomas, despite their histologically benign nature, can severely impact patients' quality of life due to hormone hypersecretion. Invasion of the medial wall of the cavernous sinus (MWCS) by these tumors complicates surgical outcomes, lowering biochemical remission rates and increasing recurrence. This study aims to share our institutional experience with the selective resection of the MWCS in endoscopic pituitary surgery.

Background: Arterial diseases like coronary artery disease, carotid stenosis, peripheral artery disease, and abdominal aortic aneurysm have high morbidity and mortality, making them key research areas. Their multifactorial nature complicates patient treatment and prevention. Biomarkers offer insights into the biochemical and molecular processes, while social factors also significantly impact patients' health and quality of life.
View Article and Find Full Text PDFAtherosclerosis and aortic aneurysms are prevalent cardiovascular diseases in the elderly, characterized by chronic inflammation and oxidative stress. This study explores the role of CircXYLT1 in regulating oxidative stress and vascular remodeling in age-related vascular diseases. RNA sequencing revealed a significant upregulation of CircXYLT1 in the vascular tissues of aged mice, highlighting its potential role in age-related vascular diseases.

Non-invasive estimation of pressure differences using 2D synthetic aperture ultrasound imaging offers a precise, low-cost, and risk-free diagnostic tool. Unlike invasive techniques, this preserves natural blood flow and avoids the limitations of devices that occupy lumen space. This paper evaluates a previously published estimator, modified to incorporate Singular Value Decomposition (SVD) echo-cancellation, using data from ten healthy volunteers and one patient.
