Vesicoureteral Reflux‚ Pediatric Vesicoureteral reflux is a condition in which urine from the bladder goes back into the tubes that connect the kidneys to the bladder (ureters). The bladder is a hollow organ in the lower part of the abdomen. It stores urine after the urine is made by the kidneys. In severe cases of vesicoureteral reflux‚ urine may flow back through the ureters and into the kidneys. Vesicoureteral reflux can affect one or both kidneys and ureters. Vesicoureteral reflux can range from

Gastroesophageal reflux disease or GERD. Gastroesophageal reflux disease (GERD) is a more serious form of gastroesophageal reflux‚ which is common. GERD occurs when the Lower Esophageal Sphincter (LES) opens spontaneously‚ for varying periods of time‚ or does not close properly and stomach contents rise up into the esophagus. GERD is also called acid reflux or acid regurgitation‚ because digestive juices called acids rise up with the food. The esophagus is the tube that carries food from

A Grignard reagent was produced by reacting ~0.15 g of magnesium metal‚ stir vane‚ 0.80 mL of bromobenzene (0.70 mL) and anhydrous diethyl ether (20.0 mL) mixture in a 20-mL round-bottom flask (reflux apparatus). The apparatus was elevated from the hot plate and heated at 60°C for 15 minutes. Brownish-gray solution was observed. The remainder bromobenzene/ether mixture was added to the round bottom flask drop-wise with additional washing of ~2
