Here, we present a novel general purpose tool called MPA (multiple peak alignment) able to perform multiple comparisons of proteomic
profiles both in a pairwise guided fashion and in a fully automatic mode using a strategy based on dynamic programing and progressive alignment of time series. The tool is available at http://grup.cribi.unipd.it/people/stefano/mpa/.”
“Studies with animal models showed that cellular, structural, and behavioral changes induced by environmental enrichment are related to increased levels of brain-derived neurotrophic factor (BDNF) in the brain. These evidence suggest that BDNF could be an interesting biomarker of the effects of lifestyle on cognition and other behavioral parameters in humans, mainly selleck chemical if the BDNF alterations in brain are accompanied by correspondent peripheral modifications, since human studies depend basically on the evaluation of this neurotrophin in Bucladesine ic50 serum or plasma. To test this hypothesis, we analyzed the effects of environmental enrichment on long-term memory for object recognition and on BDNF levels of hippocampus, frontal cortex, and serum of rats exposed to an experimental protocol that could be more easily translated to human intervention studies. Animals were maintained for 10 weeks in a social (standard laboratory conditions) or enriched (increased opportunity for physical exercise and learning
experiences) condition. In the 7th week, they were submitted to behavioral testing (open field and novel object memory task), and at the end of the 10th week, they were killed and BDNF levels were analyzed. Animals maintained in the enriched condition showed enhanced performance on the
memory task in the absence of any significant alteration in central or peripheral BDNF levels. The results of this study are important to highlight the need to develop experimental protocols using animal models that more closely resemble the characteristics of studies with humans and motivate more investigations to determine the conditions under which BDNF could be a biomarker of the effects of environment enrichment.

“Although postoperative pain remains incompletely controlled in some settings, increased understanding of its mechanisms and the development of several therapeutic approaches have substantially improved pain control in past years. Advances in our understanding of the process of nociception have led to insight into gene-based pain therapy, the development of acute opioid-induced hyperalgesia, and persistent postsurgical pain. Use of specific analgesic techniques such as regional analgesia could improve patient outcomes. We also examine the development of new analgesic agents and treatment modalities and regimens for acute postoperative pain.”
