Buckwheat has been considered as a potential source of nutraceutical components on the world market of probiotic foodstuffs. The purpose of this study was to evaluate the effects of tartary buckwheat (Fagopyrum tataricum) sprouts on oxidation and pro-inflammatory mediators.

Eosinophilic myenteric ganglionitis is a disorder characterized by infiltration of the Auerbach myenteric plexus by eosinophils. As a cause of chronic intestinal pseudo-obstruction (CIPO), eosinophilic myenteric ganglionitis has been rarely reported and the majority of the reported cases in the literature were children. We experienced a case of eosinophilic myenteric ganglionitis associated with CIPO in a 53-year-old female patient. Histologic examination of the resected descending colon showed moderate eosinophilic infiltrates with hypogangliosis in the myenteric plexus. Immunohistochemical study revealed increased number of CD4-positive lymphocytes and stronger but scantier glial fibillary acid protein expression in the inflamed myenteric plexus.

BACKGROUND AND PURPOSE: Previous studies have suggested a decreased cancer risk among patients with Alzheimer's disease (AD). There remains a lack of data on the specific types of cancer and risk factors for developing cancer in AD. We evaluated the association between AD and cancer risk, and we examined specific types of cancer. METHODS: A population-based longitudinal study was conducted using the National Health Insurance Service-Senior cohort for 2002–2013. A total of 4,408 AD patients were included in the study, as were 19,150 matched controls. Potential associations between the risk of cancer and AD were analyzed using Cox proportional hazard regressions. RESULTS: Cancer developed in 12.3% of the AD group patients and in 18.5% of control group subjects. AD was associated with a reduced risk of cancer (hazard ratio [HR], 0.70; 95% confidence intervals, 0.64–0.78). The risk of head and neck cancers was significantly reduced (HR, 0.49), as were risks for cancers of the digestive tract, including stomach cancer (HR, 0.42), colorectal cancer (HR, 0.61), liver and biliary tract cancers (HR, 0.68), and pancreatic cancer (HR, 0.55). Lung and prostate cancer risks were also significantly lower for the AD group (HR, 0.52 and HR, 0.72, respectively). CONCLUSIONS: Our results showed an inverse association between AD and cancer. Further research involving a large number of patients in a hospital based-study is needed to address the biological associations between cancer development and dementia, including AD.

This is the first case report to describe the tumor regressive effect of systemic human neural stem cell (NSC)/5-fluorocytosine (5-FC) therapy on canine metastatic lung tumor. The therapeutic effects appeared approximately two weeks after 5-FC administration. Thoracic radiographs revealed a reduced number of lung nodules and decreased nodule size. However, there were no significant antitumor effects on primary lesions in abdominal organs. In conclusion, human NSC/5-FC prodrug therapy can secure patient quality of life with the same or more therapeutic effects and fewer side effects than other recommended chemotherapies.
