We previously reported that activation of the glial-specific purinergic receptor, P2Y(1)R, reduces both astrocyte swelling and brain infarcts in a photothrombotic mouse model of stroke. These restorative effects were dependent on astrocyte mitochondrial metabolism. Here, we extend ... 552 Singh Indrapal N IN Spinal Cord and Brain Injury Research Center (SCoBIRC), Department of Anatomy and Neurobiology, University of Kentucky College of Medicine, Lexington, KY, - - 2013 Phenelzine (PZ) is a scavenger of the lipid peroxidation (LP)-derived reactive aldehyde 4-hydroxynonenal (4-HNE) due to its hydrazine functional group, which can covalently react with 4-HNE.

Inflammatory insult resulting from fatty infiltration of the liver is central to disease pathogenesis. Dendritic cells (DC) are antigen presenting cells with an emerging role in ... 598 Huang Hao - - 2013 Multiple antibiotic resistance regulator (MarR) family transcriptional regulators usually regulate gene activity by responding to specific ligands. Here we show that TamR (trans-aconitate methyltransferase regulator), a MarR homolog from Streptomyces coelicolor, functions in oxidative stress responses to regulate a key step in central metabolism. The gene encoding TamR is oriented ... 599 Cammaerts Marie-Claire - - 2013 We used the ant species Myrmica sabuleti as a model to study the impact of electromagnetic waves on social insects' response to their pheromones and their food collection. We quantified M. sabuleti workers' response to their trail, area marking and alarm pheromone under normal conditions. Then, we quantified the same ... 600 Lugo-Villarino Geanncarlo - - 2013 Monocytes are blood leukocytes that can differentiate into several phagocytic cell types, including dendritic cells (DCs), which are instrumental to the inflammatory response and host defence against microbes.
