Acute gastric volvulus following rapid and incomplete chewing of vegetables: A case report.

One of the rare but serious causes of acute abdomen is gastric volvulus. It is considered an emergent surgical condition when it takes place acutely due to the risk of gastric strangulation, gangrene, and perforation. In this study, we introduce a case of a previously healthy young adult patient who presented with sudden severe epigastric and left upper quadrant abdominal pain along with nausea and retching following insufficient mastication and rapid swallowing of large amounts of vegetables.

The assessment of honeycomb structure UiO-66 and amino functionalized UiO-66 metal-organic frameworks to modify the morphology and performance of Pebax®1657-based gas separation membranes for CO capture applications.

A new type of honeycomb structured UiO-66 metal-organic frameworks (MOF) was synthesized and amino functionalized followed by employing them to prepare mixed matrix membranes (MMM). The influences of dimethylformamide (DMF) and HO/ethanol (70/30 wt.%) blend were firstly investigated on morphology, structure, and CO/CH separation efficiency of Pebax®1657 membranes.
