Within the avian telencephalon, the dorsal ventricular ridge (DVR) contains higher order and multimodal integration areas. Using multiple regressions on 17 avian taxa, we show that an operational estimate of behavioral flexibility, the frequency of feeding innovation reports in ornithology journals, is most closely predicted by relative size of one of these(More)
Multiple sclerosis is a chronic, inflammatory, demyelinating disease of the central nervous system in which macrophages and microglia play a central role. Foamy macrophages and microglia, containing degenerated myelin, are abundantly found in active multiple sclerosis lesions. Recent studies have described an altered macrophage phenotype after myelin(More)
Cholesterol synthesis and transport in oligodendrocytes are essential for optimal myelination and remyelination in pathological conditions such as multiple sclerosis. However, little is known about cholesterol homeostasis in the myelin-forming oligodendrocytes. Liver X receptors (LXRs) are nuclear oxysterol receptors that regulate genes involved in(More)
There is abundant evidence for T-lymphocyte recruitment into the airways in allergic inflammatory responses. This study has tested the hypothesis that T-cell chemotaxis induced by platelet-activating factor (PAF) and human recombinant interleukin-8 (hrIL-8) can be attenuated by inhibition of phosphodiesterase activity and raised intracellular 3',5'-cyclic(More)
Epidemiological studies suggest a positive correlation between the incidence and severity of multiple sclerosis (MS) and the intake of fatty acids. It remains to be clarified whether high fat diet (HFD) indeed can exacerbate the disease pathology associated with MS and what the underlying mechanisms are. In this study, we determined the influence of HFD on(More)
In this article, we describe a novel straightforward method for the specific identification of viable cells (macrophages and cancer cell lines MCF-7 and Jurkat) in a buffer solution. The detection of the various cell types is based on changes of the heat transfer resistance at the solid-liquid interface of a thermal sensor device induced by binding of the(More)
Voltage-gated sodium channels (Navs) are involved in several aspects of the pathogenesis of multiple sclerosis (MS). Within acute MS plaques, they are expressed along demyelinated axons. Studies in experimental autoimmune encephalomyelitis (EAE) demonstrated a neuroprotective effect of non-specific Nav blockers. Further, block of specific Navs involved in(More)
