A breast tumour in a 47-year-old female with axillary lymph node metastasis was interpreted as the rare malignant adenomyoepithelioma based on morphological and immunohistochemical studies. Multiple bone metastases developed and the patient died after 7 months. The malignant neoplasm consisted of cords and interlacing bundles of spindle cells with(More)
BACKGROUND Glycohemoglobin (gHb), measured as hemoglobin (Hb) A(1c) or as total gHb, provides a common means for assessing long-term glycemic control in individuals with diabetes mellitus. Genetic variants and chemically modified derivatives of Hb can profoundly affect the accuracy of these measurements, although effects vary considerably among commercially(More)
The serotonin system and NMDA receptors (NMDARs) in prefrontal cortex (PFC) are both critically involved in the regulation of cognition and emotion under normal and pathological conditions; however, the interactions between them are essentially unknown. Here we show that serotonin, by activating 5-HT(1A) receptors, inhibited NMDA receptor-mediated ionic and(More)
The clinicopathological significance of colorectal mucinous carcinoma is controversial, although some authors feel mucinous carcinoma has a worse prognosis than that of non-mucinous carcinoma. To clarify the significance of this type of carcinoma in Taiwan, a retrospective review of patients with colorectal carcinoma treated at Chang Gung Memorial Hospital(More)
BACKGROUND AND STUDY AIMS Information about the appropriate endoscopic treatment of gastric variceal bleeding is sparse. We therefore designed a prospective and randomized study to evaluate and compare efficacy and complication rates of two agents, hypertonic glucose water (50% GW) and sodium tetradecyl sulfate (STS), in treating acute gastric variceal(More)
Emerging evidence has suggested that glycogen synthase kinase 3 (GSK-3) is a key regulatory kinase involved in a plethora of processes in the nervous system, including neuronal development, mood stabilization, and neurodegeneration. However, the cellular mechanisms underlying the actions of GSK-3 remain to be identified. In this study, we examined the(More)
OBJECTIVES Icteric type hepatoma caused by floating tumor debris in the major bile duct was rare. Such cases were often incorrectly identified as biliary carcinoma or choledocholithiasis until pathological proof. The goal of this study was to analyze the cholangiograms of icteric type hepatomas, and to identify the characteristic cholangiographic features(More)
An uncontrolled study for the assessment of the hemostatic effects of endoscopically injected hypertonic saline-epinephrine (HS-E) solution and pure ethanol (PE) was carried out in 67 patients with nonvariceal gastrointestinal bleeding. The HS-E group included duodenal ulcer (18), gastric ulcer (9), gastric cancer (2), polyp (2), marginal ulcer (1), and(More)
