Children born to women who experience stress during pregnancy have an increased risk of cancer in later life, but no previous animal studies have tested such a link. We questioned whether prenatal stress in A/J mice affected the development of lung tumors after postnatal response to tobacco specific nitrosamine, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). Timed-bred A/J mice were randomly assigned on gestation day 12.5 to prenatal stress (PS) by restraint for 5 consecutive days or cont...

No difference in the gene methylation status of tumor-suppression genes between pancreatic cancer tissues and adjacent non-cancer tissues is observed. The present study investigated whether the promoter CpG islands of the cysteine dioxygenase 1 (CDO1), tachykinin precursor 1 (TAC1) and checkpoint with forkhead and ring finger domains (CHFR) genes were methylated in pancreatic cancer and adjacent non-cancerous pancreatic tissue in order to determine if they could be considered as markers for the ...

Background. Percutaneous endoscopic gastrostomy (PEG) is the standard modality for long-term enteral nutrition for patients with dysphagia. Compared with open gastrostomy, though PEG is an extremely safe procedure with fewer complications, there are severe cases due to anatomical features. For these cases, laparoscopic-assisted percutaneous endoscopic gastrostomy (LAPEG) is the optimal method. Case Presentation. A 52-year-old man had a disturbance in swallowing because of cerebral infarction. We...

Predicting malignancy is important for adequate adjuvant therapy in patients with cancer. Due to cancer being a genetic disease, the detection of gene mutations could be helpful in predicting the prognosis and efficacy of drugs. Gastric cancer is the fifth most common cancer and is the third leading cause of cancer associated mortality worldwide. Mutations in genes may correlate with clinical information in patients with gastric cancer after surgery and, therefore, may be useful for predicting t...

Abstract Background Esophageal squamous cell carcinoma (ESCC) is common in East Asia and also is often deadly. We sought to determine whether measuring the discoidin domain receptor-1 (DDR1)—both total and phosphorylated proteins—could improve our ability to predict recurrence in ESCC. Materials and Methods Total DDR1 and phosphorylated DDR1 (pDDR1) were measured using semiquantitative immunohistochemistry in a cohort of 60 patients with ESCC. Association between these immunohistochemical measur...

Introduction. There are many possible causes of an abdominal visceral aneurysm, including the obstruction of the celiac artery by the median arcuate ligament (MAL). We report two cases of an aneurysm of the pancreaticoduodenal artery due to MAL syndrome that we treated surgically. Case Presentation. Case 1: a 66-year-old Japanese woman was diagnosed with a rupture of an aneurysm of the inferior pancreaticoduodenal artery. Because of the difficulty of endovascular therapy, we performed an emergen...

Background Although primary (PGC) and remnant gastric cancers (RGC) both originate from the same gastrointestinal organ, they have very distinct clinicopathological behaviors. We hypothesized that there would be distinct differences in DNA methylation patterns that would occur during carcinogenesis of RGC and PGC, and that the differences in methylation patterns may help identify the primary factor contributing to chronic inflammation in patients with RGC.
