Simultaneous Laryngopharyngeal and Conventional Esophageal pH Monitoring06:46

Simultaneous Laryngopharyngeal and Conventional Esophageal pH Monitoring

Laryngopharyngeal pH monitoring has been specifically designed to measure acid exposure above the upper esophageal sphincter and complements diagnostic evaluation in patients that present with mainly extraesophageal reflux symptoms. Patients with suspected laryngopharyngeal reflux (LPR) were evaluated using distal esophageal and laryngopharyngeal pH testing...

Alkaline Single Cell Gel Electrophoresis: A Sensitive Technique for Quantitative Estimation of DNA Damage in Individual Cancer Cells Following Chemotherapy05:06

Alkaline Single Cell Gel Electrophoresis: A Sensitive Technique for Quantitative Estimation of DNA Damage in Individual Cancer Cells Following Chemotherapy

In this video, we demonstrate an alkaline single-cell electrophoresis assay to quantify both single- and double-strand DNA breaks in doxorubicin-treated cells. Alkaline conditions disrupt the hydrogen bonds between DNA base pairs, resulting in the complete unwinding and separation of DNA strands. This allows differential migration of undamaged and damaged DNA fragments in agarose gel upon electrophoresis, revealing a comet-shaped structure of slowly migrating undamaged DNA forming the circular...

Esophageal 3D Raft Culture Model: An In Vitro Culture Technique to Generate Human Esophageal Mucosa Model

This video describes an in vitro culture technique to generate human organotypic esophageal constructs by co-culturing primary human esophageal fibroblast and squamous epithelial cells within a decellularized porcine scaffold. These 3D culture models mimic the function and physiology of their in vivo tissue...

Esophageal Varices-I: Introduction01:24

Esophageal Varices-I: Introduction

Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...
