Immortalization of Human Adult Alveolar Epithelial Cells to Study Environmental Exposures of the Distal Lung

Current Protocols, Volume 6, Issue 5, May 2026.
Abstract Alveolar epithelial cell type 1 (AT1) and type 2 (AT2) cells make up the saccular gas exchange units of the lung, called alveoli. Formation of alveoli during lung development accounts for the expansive surface area of the lung, allowing for proper respiration and delivery of oxygen to the body.

Occult Hepatitis B Virus Infection and Hepatocellular Carcinoma

The Korean Journal of Gastroenterology, 2013
Many studies have suggested that occult HBV infection has a substantial clinical relevance to hepatocellular carcinoma (HCC). Occult HBV infection is an important risk factor for the development of cirrhosis and HCC in patients without HBsAg. As a matter of fact, occult HBV infection is one of the most common causes of crytogenic HCC in endemic areas ...

Delayed diagnosis of 3β‐HSD7 deficiency in adolescence: Two case reports and review of the literature

JPGN Reports, Volume 7, Issue 2, Page 236-241, May 2026.
Abstract Congenital bile acid synthesis defects (BASD), the most common of which is 3β‐hydroxy‐Δ5‐C27‐steroid dehydrogenase oxidoreductase (3β‐HSD7) deficiency, are a rare cause of fat‐soluble vitamin malabsorption. We describe a 14‐year‐old girl who presented at 14 months with a left distal femur fracture and failure to thrive.
