Some cytokines have been involved in the pathogenesis of late onset Alzheimer's disease (LOAD). A possible increase in plasma cytokines levels has been reported in LOAD and vascular dementia (VD), but the results of previous studies are conflicting. We evaluated the plasma levels of IL-6, TNF-alpha, IL-1beta, and IL-10 in four groups of older individuals:(More)
In older individuals, inflammatory mechanisms have been linked to the pathogenesis of both dementia and functional impairment. In this cross-sectional study we have investigated the possible association between some markers of systemic inflammation and functional status, in a sample of one hundred and forty older demented patients including 60 patients with(More)
Stim1 and Orai1 are ubiquitous proteins that have long been known to mediate Ca(2+) release-activated Ca(2+) (CRAC) current (ICRAC) and store-operated Ca(2+) entry (SOCE) only in non-excitable cells. SOCE is activated following the depletion of the endogenous Ca(2+) stores, which are mainly located within the endoplasmic reticulum (ER), to replete the(More)
Effects of short-term repeated blood sampling on the secretion of corticosterone (CORT) and beta-endorphin (beta-END) were evaluated in male Wistar rats. Blood was drawn from the tail vein of conscious rats four times within 2 h both at the peak and trough period of the diurnal corticosterone secretion cycle. All rats were well accustomed to the procedure.(More)
The aim of this study has been to visualize the aqueous outflow system in patients affected by primary open angle glaucoma. A solution of indocyanine green (ICG) plus high viscosity viscoelastic solution was injected into the Schlemm canal during surgery in 10 glaucomatous patients undergoing canaloplasty. Soon after injection of the dye the borders of the(More)
Endothelial injury is the primary event that leads to a variety of severe vascular disorders. Mechanical injury elicits a Ca(2+) response in the endothelium of excised rat aorta, which comprises an initial Ca(2+) release from inositol-1,4,5-trisphosphate (InsP(3))-sensitive stores followed by a long-lasting decay phase due to Ca(2+) entry through uncoupled(More)
BACKGROUND Endothelial progenitor cells (EPCs) may be recruited from bone marrow to sustain tumor vascularisation and promote the metastatic switch. Understanding the molecular mechanisms driving EPC proliferation and tubulogenesis could outline novel targets for alternative anti-angiogenic treatments. Store-operated Ca(2+) entry (SOCE), which is activated(More)
The human formyl-peptide receptor (FPR) and its variants FPRL1 and FPRL2 belong to the G-protein coupled seven transmembrane receptor (GPCR) family sensitive to pertussis toxin. FPR and FPRL1 were first detected in phagocytic leukocytes, and FPRL2 was found in monocytes and in dendritic cells. The three receptors were subsequently identified in other cell(More)
This paper deals with the optimal control of systems governed by non-linear systems of conservation laws at junctions. The applications considered range from gas compressors in pipelines to open channels management. The existence of an optimal control is proved. From the analytical point of view, these results are based on the well posed-ness of a suitable(More)
