2022 Egyptian Liver Journal  
Background Early detection of hepatocellular carcinoma (HCC) is crucial for improving the survival rate for patients. Talin-1 is first identified as a cytoskeleton protein that is required for cell adhesion and motility and plays a role in tumor migration and metastasis. In the present work, we aimed to study the possible role of Talin1 compared to alpha fetoprotein (AFP) in the diagnosis and prognosis of HCC. Methods To achieve this goal, serum levels of Talin-1 were measured using
more » ... d immunosorbent assay (ELISA) in 90 patients divided into four groups. Group I: 30 patients with early HCC. Group II: 30 patients with late HCC according to Modified Barcelona-Clinic Liver Cancer (BCLC). Group III: 15 patients with liver cirrhosis, and group IV: 15 healthy controls. Receiver operating characteristics (ROC) curve analysis was used to create a predictive model for Talin-1 relative to AFP in HCC diagnosis. Results It was found that serum Talin-1 in HCC patients was significantly higher compared to its level in cirrhotic patients and the healthy control group. Talin-1 was superior to AFP regarding sensitivity, specificity, positive, and negative predictive value in the diagnosis of HCC. We also found a significant positive correlation between serum Talin-1 and the degree of tumor burden of HCC (BCLC staging), tumor size, and vascular invasion. Conclusion Talin-1 holds a promise as a potential marker for HCC diagnosis and prognosis.

Severe Pulmonary Arterial Hypertension: Comprehensive Evaluation by Magnetic Resonance Imaging

El-Sayed H. Ibrahim, Abubakr A. Bajwa
2015 Case Reports in Radiology  
Pulmonary arterial hypertension (PAH) is characterized by elevated pulmonary artery (PA) pressure, which negatively affects the right ventricular (RV) function. This report shows a patient with severe PAH, on whom a comprehensive MRI exam was performed to evaluate both PA and RV. New imaging sequences were implemented for obtaining additional parameters about the patient's condition. The results show the capabilities of the developed exam of providing complete picture of the cardiovascular
