Severity of Rheumatic Mitral Stenosis: A Comparative Study of Mitral Leaflet Separation Index versus Mitral Valve Area.

Introduction: Assessing the severity of mitral stenosis (MS) is crucial for predictive and therapeutic purposes. While methods like planimetry and Pressure half time (PHT) are considered gold standard for measuring mitral valve area (MVA), they can be operator-dependent or influenced by hemodynamic factors. Our study evaluates the accuracy of mitral leaflet separation index (MLSI) as an alternative tool for assessing rheumatic MS severity, considering its independence from hemodynamic variations.

Efficacy of acetylcholinesterase inhibitors on reducing hippocampal atrophy rate: a systematic review and meta-analysis.

Background: Neurodegenerative diseases (NDs) are conditions characterized by irreversible progressive degeneration to the nervous tissue and are usually associated with cognitive decline and functional deficits, especially in elderly.

Echocardiographic Evaluation in Cardiac Resynchronization Therapy: A Single Center Experience.

Introduction Heart failure develops as a result of dysfunction in the cardiac muscle, which impairs the heart's ability to pump blood effectively. For this reason, many studies have shown that cardiac resynchronization therapy (CRT) has significantly reduced symptoms and improved cardiac function in patients with heart failure. Echocardiography is crucial in assessing CRT response, as it helps differentiate between patients who benefit from CRT and those who do not by evaluating key parameters like left ventricular ejection fraction (LVEF), a critical parameter in determining CRT eligibility.

The FSCN1 gene rs2966447 variant is associated with increased serum fascin-1 levels and breast cancer susceptibility.

Fascin-1 (FSCN1) is recognized as an actin-binding protein, commonly exhibits up-regulation in breast cancer (BC) and is crucial for tumor invasion and metastasis. The existence of FSCN1 gene polymorphisms may raise the potential for developing BC, and there are still no studies focusing on the relationship between the FSCN1 rs2966447 variant and BC risk in Egyptian females. Thus, we investigated the serum fascin-1 levels in BC patients and the association between the FSCN1 rs2966447 variant with its serum levels and BC susceptibility.

Purpose: Macrophage migration inhibitory factor (MIF) is an integral cytokine for the modulation of both innate and adaptive immunity and is involved in the pathogenesis of various cancers. However, conflicting findings on the relationship between MIF polymorphisms and breast cancer (BC) have been reported in earlier research. We investigated the clinical value of serum MIF levels and the association between MIF rs1049829 and rs755622 variants with their serum levels and propensity to develop BC.

A new label free spiral sensor using impedance spectroscopy to characterize hepatocellular carcinoma in tissue and serum samples.

Hepatocellular carcinoma (HCC) stands as the most prevalent form of primary liver cancer, predominantly affecting patients with chronic liver diseases such as hepatitis B or C-induced cirrhosis. Diagnosis typically involves blood tests (assessing liver functions and HCC biomarkers), imaging procedures such as Computed Tomography (CT) and Magnetic Resonance Imaging (MRI), and liver biopsies requiring the removal of liver tissue for laboratory analysis. However, these diagnostic methods either entail lengthy lab processes, require expensive imaging equipment, or involve invasive techniques like liver biopsies.

Iodide ion-imprinted chitosan beads for highly selective adsorption for nuclear wastewater treatment applications.

Iodide ions from radioactive iodine isotopes are common contaminants present in nuclear wastewater from nuclear power plants which are considered hazardous contaminants to be released in water sources even at low concentrations due to their association with metabolic disorders, therefore its removal from the nuclear wastewater effluents is necessary. Chitosan beads are natural and cost-efficient adsorbents that have been used for ion removal from wastewater. However, issues of poor selectivity persist in achieving high-efficiency iodide ion removal.
