Methods: Relevant studies were identified through PubMed and Web of Knowledge databases, studies included were those published up until to May 2012. Study quality was assessed according to the HuGENET guidelines and Strengthening the Reporting of Genetic Association (STREGA) recommendations. Results: Random-effects meta-analysis provided evidence that carriers of DPYD IVS14+1G>A are at higher risk of 3 degrees of overall grade

toxicity, hematological toxicity, mucositis and diarrhea. In addition, a strong association was also found between carriers of the DPYD 2846T allele and overall grade 3 toxicity or grade 3 diarrhea. An inverse linear relationship selleck chemicals was found in prospective studies between the odds ratio of DPYD IVS14+1G>A and the incidence of overall grade 3 toxicity, indicating an higher impact in cohorts in which the incidence of severe toxicity was lower. Conclusion: The results of this meta-analysis confirm clinical validity of DPYD IVS14+1G>A and 2846A>T as risk factors for the development of severe toxicities following fluoropyrimidine treatment. Furthermore, the sensitivity and specificity estimates obtained could be useful in establishing the cost-effectiveness of testing for

DPYD variants. Original submitted 4 March 2013; Revision submitted 17 June 2013″
“3-Nitropropionic acid (NPA) produces degeneration of striatum and some neurological disturbances Nocodazole chemical structure characteristic Selleckchem AZD5363 of Huntington’s disease in rodents and primates. We have shown that the flavonoid kaempferol largely reduced striatal damage induced by cerebral ischaemia-reperfusion in rats (Lopez-Sanchez et al. 2007). In this work, we report that intraperitoneal (i.p.) administration of kaempferol affords an efficient

protection against NPA-induced neurodegeneration in Wistar rats. We studied the effects of daily i.p. injections of 7, 14 and 21 mg of kaempferol/kg body weight during the NPA-treatment (25 mg/kg body weight/12 h i.p., for 5 days) on the neurological deficits, degeneration of rat striatum and oxidative stress markers. Intraperitoneal injections of 14-21 mg of kaempferol/kg body weight largely attenuated motor deficit and delayed mortality. The higher dose of kaempferol prevented the appearance of NPA-induced striatal lesions up to the end of treatment, as revealed by haematoxylin-eosin and TUNEL staining, and also NPA-induced oxidative stress, because it blocked the fall of reduced glutathione and the increase of protein nitrotyrosines in NPA-treated rats. It was found that striatal degeneration was associated with calpains activation and a large inactivation of creatine kinase, which were also prevented when the higher doses of kaempferol were administered.
