Study design. One hundred five neck dissections were performed in 90 patients with oral cancer: 4 RNDs and 101 modified radical neck dissections (mRNDs). The spinal accessory nerve was preserved in 96 neck EGFR inhibitors cancer dissections. Dysfunction of the trapezius muscle was evaluated by the limitation of shoulder lateral abduction at 3 months after the operation.

Results.

All 9 patients with resection of the spinal accessory nerve showed severe shoulder dysfunction, whereas 90 out of 96 with preservation of the nerve maintained normal shoulder function.

Conclusion. Spinal accessory nerve-sparing neck dissection can reduce postoperative shoulder dysfunction if careful operating procedures are used. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2010; 109: 820-824)”
“Meat and seafood chemical contaminants can be very dangerous for human health. The way in which food chemical contaminants are currently controlled is not optimal as the food cooking, processing and eating habits are generally not considered by authorities. The current review discusses the available information related to the toxicity of the most relevant meat and seafood chemical contaminants, their bioaccessibility after cooking or processing, and the implications for human health.

In addition, the current in vivo toxicity and alternative tests carried out for testing the effects of food chemical contaminants are illustrated, as well as new detection tools. The use of non-carcinogenic functional cell models, HDAC activation of alternative animal models like zebrafish embryos, and a toxicogenomic approach seem to be the most promising strategy for the toxicity assessment of food chemical contaminants.

“The

rotational mobility of molecules in glassy polymers was investigated by quantitative simulations of electron spin resonance spectra of nitroxide spin probes with molecules of different sizes. The motional Nepicastat mw models were determined unambiguously when the experimental and calculated spectra coincided within the level of experimental error. Temperature ranges in which different motional models were applicable were determined. Quasi-librational movements and the distribution of rotational mobility were found to be necessary for the qualitative description of spin-probe mobility in glassy polymers. The quantitative and empirical characteristics of rotational mobility were examined. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 121: 102-110, 2011″
“Recently, a great deal of interest has been developed by the consumers towards natural bioactive compounds as functional ingredients in the food products due to their various health beneficial effects. Hence, it can be suggested that antioxidative functional ingredients from marine foods and their by-products are alternative sources for synthetic ingredients that can contribute to a consumer’s well-being, as a part of nutraceuticals and functional foods.
