The systemic failure of CaM degradation, and thus of Ca2+/CaM-dependent signaling pathways, may be important in the etiopathogenesis of AD.”
“The unparalleled accumulation of biological and contextual data is currently revolutionizing the way environmental microbiologists

address ecological questions. Here, we briefly review the likely causes that may explain this remarkable scientific revolution and present a synthesized view about how to describe microbial communities in their complex environmental context.”
“We demonstrate-both experimentally and theoretically-that the finite size of the current leads does not allow neglecting the role of these leads in the four-probes transport measurements if the properties LDK378 mouse of these leads are modified in the course of the experiment. We also give a short critical review of other publications, where, to our opinion, a possible role of the current leads was underestimated. (C) 2011 American Institute of Physics.

“Hypertension selleck kinase inhibitor causes cognitive impairment, involving mainly executive functions, but the effect of blood pressure (BP) control on the different cognitive domains is still debated. We correlated executive function, attention and memory with BP control and cerebrovascular damage in 60 undemented middle-aged hypertensives at baseline and

after 6-year follow-up. At first evaluation, the patients with poor BP control had higher score of white matter lesions, reduced cerebrovascular reserve capacity and

greater carotid intima-media thickness (IMT) than those with good BP control. Performance on executive tests correlated with IMT and with performance on attention tests, which was impaired by low diastolic BP. At long-term follow-up, performance in attention and executive tests improved in spite of the minor improvement of BP control, increased IMT and worse memory. Low diastolic BP has a negative effect on attention, which affects executive performance at first cross-sectional examination. This confounding effect has to be taken into consideration when planning studies on cognitive function. Longitudinal studies are required to unravel the effect of BP Dinaciclib purchase control on cognitive function, as only long-term antihypertensive treatment improves both attention and executive performance.

“Neurogenesis in the hippocampus is actively involved in neural circuit plasticity and learning function of mammals, but it may decrease dramatically with aging and aging-related neurodegenerative disorder Alzheimer’s disease. Accumulating studies have indicated that Wnt/beta-catenin signaling is critical in control of proliferation and differentiation fate of neural stem cells or progenitors in the hippocampus.
