45, 46 Those markers were found to be down-regulated upon HO-1 induction, further indicating inhibition of proliferation. These results are in line with XL765 molecular weight our observation that HO-1 induction reduced early signs of dysplasia and indicate that HO-1 induction at early time points (e.g., during inflammation or fibrosis) might have consequences on subsequent progression to HCC. Preliminary results even indicate that early HO-1 induction might interfere with progression to HCC. HO-1 has been shown to be overexpressed in alcohol-induced HCC in patients.47 Moreover, HO-1 down-regulation via short interfering
RNA significantly decreased tumor growth, whereas it increased cellular damage and apoptosis.47 Therefore, in the liver, HO-1 overexpression seems to exert beneficial Sunitinib ic50 or detrimental effects, depending on pathological conditions (e.g., inflammation or solid tumor formation). However, tumor-promoting effects by early HO-1 induction are unlikely, because induced HO-1 protein is degraded within days after treatment, whereas anti-inflammatory effects of HO-1 induction seem to last for at least 8 weeks longer than treatment with CoPP. Therefore, follow-up experiments have to determine the consequences of early HO-1
induction on progression to HCC caused by chronic inflammation. The expert technical assistance by Elena Tassika, Christine Loscher, and Nicola Peters find more is gratefully acknowledged. Additional Supporting Information may be found in the online version of this article. “
“Background and Aim: The Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease (FSSG) is the standard questionnaire used in
Japan for the diagnosis of gastroesophageal reflux disease (GERD) and assessment of the response to treatment. We modified the FSSG in order to assess dyspepsia symptoms, and evaluated the modified questionnaire. Methods: We modified the FSSG by adding two questions on interdigestive and postprandial epigastric pain. We then assessed the modified FSSG with 100 new untreated symptomatic patients presenting to hospital and in 200 subjects undergoing health checks. Endoscopic assessment of the esophagogastric junction was performed according to the modified Los Angeles classification with addition of Grade N (normal appearance) and Grade M (minimal change). Endoscopic images were assessed by five experienced endoscopists blinded to the questionnaire results. Results: The 100 new patients included 16 with erosive GERD (>Grade A), 12 with peptic ulcer, and two with gastric cancer. Among the 70 patients with no evidence of organic disease, the modified FSSG diagnosed functional dyspepsia (FD) in 41 and non-erosive gastric disease (NERD) in 29. A significant difference was seen in the dyspepsia score between patients with FD and NERD.
