Eating habits and dietary patterns in children with autism.

The children with autism have feeding problems such as chewing, preference for the same food that often are responsible for the nutrient imbalance. In this study, we have analyzed the differences in food consumption (food frequency) and eating behavior (CEBI test) between children with autism and their typically developing peers. A statistically significant difference was observed between the two groups for the consumption of milk, yogurt, pulses, rice, and fruit juices (p ≤ 0,005). We observed a significant difference in the analysis of CEBI results when considering the 6- to 9.5-year-aged subgroup with autism vs control subgroup (103.50 and 110.14, respectively). The advices given by nutritionists have proved crucial to improve eating habits in children with autism, in the follow-up.

Sodium butyrate sensitises human pancreatic cancer cells to both the intrinsic and the extrinsic apoptotic pathways.

Pancreatic cancer is characterised by a highly malignant phenotype with a marked resistance to conventional therapies and to apoptotic activators. Here, we demonstrate that sodium butyrate (NaBt), an inhibitor of histone deacetylases, sensitises human pancreatic cancer cell lines to both mitochondria- and Fas-mediated apoptosis. The analysis of anti-apoptotic and pro-apoptotic members of the Bcl-2 family in untreated pancreatic cancer cell lines shows a generalised low expression of Bcl-2 and a strong expression of Bcl-xL. NaBt treatment results in a marked down-regulation of Bcl-xL expression, mitochondrial membrane depolarization, cytochrome c release from mitochondria, activation of caspase-9 and -3 and apoptosis induction. Furthermore, NaBt sensitises pancreatic cancer cells to Fas-mediated apoptosis as well. In fact, the combined treatment with NaBt and the agonistic antibody anti-Fas (CH11) is able to induce apoptosis at an early time, in which neither NaBt nor CH11 alone induce apoptosis. Down-regulation of FLIP and activation of caspase-8 allow apoptosis to occur. These findings suggest that sodium butyrate could represent a good candidate for the development of new therapeutic strategies aimed at improving chemotherapy and immunotherapy in pancreatic cancer.
