Full-text (PDF) | Human red cell AQP1 is the first functionally defined member of the aquaporin family of membrane water channels. Here we describe an atomic model of AQP1 at 3.8A resolution from electron crystallographic data. Multiple highly conserved amino-acid residues stabilize the novel fold...
Hepatocellular ballooning is a key feature required for the diagnosis of NASH and a component of currently used histological grading and staging systems of NAFLD.he rearrangement of the intermediate filament cytoskeleton can be demonstrated by the loss of keratin 8/18 immunostaining of the cytoplasm, and may thus be evaluated in the future as a marker for the more objective detection of hepatocellular ballooning in NASH.
A hepatocellular adenoma is a relatively uncommon noncancerous liver tumor that may be mistaken for cancer. Rarely, it ruptures and bleeds or becomes cancerous. Hepatocellular adenomas occur mainly in women of childbearing age, particularly those who use oral contraceptives. Usually, these tumors cause no symptoms, so most remain undetected. Large adenomas may cause pain in the upper right part of the abdomen. Rarely, a hepatocellular adenoma suddenly ruptures and bleeds into the abdominal cavity, requiring emergency surgery. Very rarely, these tumors become cancerous.
