Process Development for the Detoxification of Fermentation Inhibitors from Acid Pretreated Microalgae Hydrolysate.

The aim of this study was to remove 5-hydroxymethyl furfural (5-HMF) and furfural, known as fermentation inhibitors, in acid pretreated hydrolysates (APH) obtained from using activated carbon. Microwave-assisted pretreatment was used to produce APH containing glucose, xylose, and fermentation inhibitors (5-HMF, furfural). The response surface methodology was applied to optimize key detoxification variables such as temperature (16.

Clinical outcomes of upper gastrointestinal bleeding in patients with gastric gastrointestinal stromal tumor.

Background: Upper gastrointestinal bleeding (UGIB) is one of the major manifestations of gastrointestinal stromal tumor (GIST) of the stomach. Several studies have reported that GIST bleeding is associated with poor prognosis. However, only case reports have reported hemostasis modalities for treating hemorrhagic gastric GIST.

Portal biliopathy treated with endoscopic biliary stenting.

Portal biliopathy is defined as abnormalities in the extra- and intrahepatic ducts and gallbladder of patients with portal hypertension. This condition is associated with extrahepatic venous obstruction and dilatation of the venous plexus of the common bile duct, resulting in mural irregularities and compression of the biliary tree. Most patients with portal biliopathy remain asymptomatic, but approximately 10% of them advance to symptomatic abdominal pain, jaundice, and fever.

A large-sized phytobezoar located on the rare site of the gastrointestinal tract.

Bezoars are concretions of undigested material and are most often observed in the stomach. They can occur at any site in the gastrointestinal tract; however, duodenal localization is very rare. We report the case of a 71-year-old male who had undergone subtotal gastrectomy with gastroduodenostomy and experienced severe epigastric discomfort, abdominal pain, and vomiting for a few days.

Two Cases of Diffuse Large B-Cell Lymphomas in the Cervical Lymph Nodes in Patients with Low-Grade Gastric Marginal Zone B-Cell Lymphoma (MALT Lymphoma).

It is well known that gastric mucosa-associated lymphoid tissue (MALT) lymphomas are associated with Helicobacter pylori infection and have a good prognosis. However, although rare, these low-grade lymphomas transform to the high-grade diffuse large B-cell lymphomas (DLBCLs) which are thought to be the important cause of death in patients with MALT lymphoma. We report two cases of DLBCLs in the cervical lymph nodes that occurred 10 years and 1.
