A Hepatocelluar Co-Culture System for the Investigation of Cellular-Based Mechanisms of Troglitazone-Induced Liver Injury

Drug-induced liver injury (DILI) is a serious issue faced by the pharmaceutical industry, and often leads to drug withdrawal once patients experience drug-induced severe hepatic failure. We developed an in vitro assay system that enables to assess cellular damage and immune reaction responses that ultimately result in DILI using troglitazone as a model drug….

Three Cases of Intentional Ingestions of Intact Cellular Phones Retrieved from the Gastrointestinal Tract

Foreign bodies in the gastrointestinal tract are frequently encountered by gastroenterologists. This in- cludes ingestions as well as insertions via the rectum. However, ingestions/insertions of intact cellular phones are rare. We present a case series of small cellular telephones which were removed from the gastrointestinal tract. Two in separate

Prognostic Variables for Patients with T2N0M0 Esophageal Squamous Cell Carcinoma

To explore the variables which could predict the prognosis and might be considered as staging factors in patients with T2N0M0 Esophageal Squamous Cell Carcinoma (ESCC).Records of 525 patients with pathologic T2N0M0 ESCC who underwent surgical resection were reviewed. The T2 category was further subdivided into T2a (circular muscle layers) and T2b (longitudinal muscle layers)….

Some authors suggest that postoperative pancreatitis is a severe complication that should be treated conservatively and operatively if needed. Other authors defend an opposite opinion that only postoperative hyperamylasemia exists, which is a transitory condition with no risk …
