BACKGROUND To detect the expression of glutathione S-transferase Pi(GST-pi), multidrug resistance-associated protein (MRP), lung-resistance protein(LRP), multidrug resistance gene1 (MDR1) and MGr1 antigen(MGr1-Ag) in the patients with primary gastric cancer and without any prior chemotherapy and to evaluate the correlations between them. PATIENTS AND(More)
BACKGROUND Transient receptor potential channel vanilloid subfamily member-1 (TRPV1) may play a role in esophageal perception. TRPV1 mRNA and protein expression were examined in the esophageal mucosa of non-erosive reflux disease (NERD) and erosive esophagitis (EE) patients and correlated to esophageal acid exposure. METHODS Seventeen NERD patients, eight(More)
OBJECTIVES To determine whether patients with Alzheimer's disease (AD) and coexisting cerebral infarction (CI) that satisfy the National Institute for Neurological Disorders and Stroke/Association Internationale pour la Recherche et l'Enseignement en Neurosciences (NINDS-AIREN) neuroimaging criteria for vascular dementia (VaD) progress faster than those who(More)
BACKGROUND A distinction between symptomatic non-erosive reflux disease (NERD) and erosive esophagitis (EE) patients is supported by the presence of inflammatory response in the mucosa of EE patients, leading to a damage of mucosal integrity. To explore the underlying mechanism of this difference, we assessed inflammatory mediators in mucosal biopsies from(More)
Haepatocellular carcinoma (HCC) is the most common primary liver malignancy, representing the fifth most common cancer in the world. Without treatment, the median survival of HCC patients has been reported to be 8 weeks from symptomatic presentation. Transarterial chemoembolisation is widely used to manage unresectable HCCs. However, when a tumour is large(More)
Gastro-intestinal stromal tumours are rarely found in the oesophagus and it is uncommon for these tumours to present with rupture. In this paper, we report a case where the tumour ruptured through the distal oesophagus. As a result, the patient underwent surgical tumour dissection. A histopathological examination of the tumour mass confirmed that it was a(More)
Distraction osteogenesis was used to correct congenital hand deformities in 12 digits. The patients' ages at the time of distraction ranged between 2.5 and 7 years. A total of nine patients underwent lengthening of 12 bones. The average period of distraction was 31.1 +/- 17.6 days. The average length of distraction was 23.6 +/- 7.3 mm. Seventeen percent of(More)
Nellix Endovascular Aneurysm Sealing (EVAS) system is a new concept and technology of abdominal aortic aneurysm (AAA) repair. Elective EVAS using Nellix device was performed for a 83-year-old man with AAA. 2-month post-EVAS CTA surveillance demonstrated mild enlargement of aneurysmal sac and separation of the EndoBags, but without detectable endoleak. The(More)
The DDT1 MF2 smooth muscle tumor cell line was derived from an estrogen/androgen-induced leiomyosarcoma that arose in the ductus deferens of a Syrian hamster. The growth of this cell line is arrested at the G0/G1 phase of the cell cycle after treatment with glucocorticoids. To identify the putative gene(s) that are potentially involved in this(More)
