The dual activation of TLR4 in adipocytes by lipopolysaccharide and fatty acids represents a molecular gate that connects innate immunity with metabolism. Dichotomic molecules derived from ancient precursor molecules control metabolism and immune function. Visceral adipose tissue is infiltrated by macrophages in obesity, and there is local crosstalk between these two types of cells, leading to an inflammatory transformation of adipose tissue.”
“Growing evidence supports the notion that the same brain
areas involved in planning and execution of movements are also involved in verb processing. Recent studies have pointed out the existence of click here verb impairment in patients with Parkinson’s disease (PD), a neurodegenerative disorder typically characterized by motor disturbance related to dopamine deficiency in the nigrostriatal system. The aim of this study was to test the influence of dopaminergic treatment in a group of non-demented PD patients on the performance of action naming. The action pictures belonged to two categories: pictures with high and low degree of motor content. A group of 20 PD patients without dementia and 15 controls performed the task. PD patients were assessed twice, on and off medication, controls only once.
A repeated measures ANOVA was carried out on the reaction times. The results showed a main effect of group and a significant interaction between group x motor content when comparing
the three groups. When the comparison was made only on the PD groups (on Dactolisib chemical structure vs. off medication) the interaction group x motor content was also significant, indicating that PD patients off medication had longer reaction times for pictures with a high degree of motor content compared to PD patients on medication. These results suggest a selective deficit in naming pictures associated with high motor content in PD patients without dopamine medication. This effect could be due to the relations between brain motor areas and verb processing associated HKI-272 mw with dopamine depletion. (c) 2012 Elsevier Ireland Ltd. All rights reserved.”
“The high resolution 2-D protein gel electrophoresis technique combined with MALDI-TOF MS and a recently developed fluorescence-based thiol modification assay were used to investigate the cellular response of Staphylococcus aureus to oxidative stress. Addition of hydrogen peroxide, diamide, and the superoxide generating agent paraquat to exponentially growing cells revealed complex changes in the protein expression pattern. In particular, proteins involved in detoxification, repair systems, and intermediary metabolism were found to be up-regulated. Interestingly, there is only a small overlap of proteins induced by all these stressors.
