BACKGROUND The aim of this study was to determine the long-term outcomes of surgical angioplasty for left main coronary artery (SA-LMCA) stenosis. METHODS We retrospectively analyzed data from 24 consecutive patients (mean age, 55 years; male/female, 12/12) who underwent a surgical angioplasty for the left main coronary artery (LMCA) stenosis at our institution between 1995 and 2002. We used ...
UNLABELLED We have previously reported the results of a 1-y double-blind, placebo-controlled study of embryonic dopamine cell implantation for Parkinson's disease. At the end of the blinded phase, we found a significant increase in putamen uptake on (18)F-fluorodopa ((18)F-FDOPA) PET reflecting the viability of the grafts. Nonetheless, clinical improvement was significant only in younger (age <...
PRIMARY MESSAGE: The idea that synaptic long-term potentiation (LTP) is the substrate of learning remains controversial. Nevertheless, several lines of evidence have linked it to memory, particularly spatial memory in rats. Induction of LTP is via a postsynaptic calcium signal generated through glutamate NMDA receptors. Expression is mediated by phosphorylation of pre-existing AMPA receptors an...
PURPOSE We aimed to describe the long-term outcome of endovascular treatment of iliofemoral deep vein thrombosis in the postpartum period. MATERIALS AND METHODS Between 2002 and 2010, 18 consecutive female patients with acute or subacute iliofemoral deep vein thrombosis in the postpartum period who had endovascular treatment were retrospectively evaluated. Treatment consisted of manual aspira...
Dwarf mistletoes, obligate, parasitic plants with diminutive aerial shoots, have long-term effects on host tree water relations, hydraulic architecture and photosynthetic gas exchange and can eventually induce tree death. To investigate the long-term (1886-2010) impacts of dwarf mistletoe on the growth and gas exchange characteristics of host western hemlock, we compared the diameter growth and...
The aims of the present study were to compare the levels of mRNA and protein expression of matrix metalloproteinase (MMP)-1, -3, -8 and -9 in human cervical tissue in preterm and term labor as well as not in labor and to determine if corticotropin-releasing hormone (CRH) has an effect on MMP-1, -3 and interleukin (IL)-8 secretion in both preterm and term cervical fibroblasts. Cervical biopsies ...
review and classification of electric load forecasting (lf) techniques based on artificial neuralnetworks (ann) is presented. a basic anns architectures used in lf reviewed. a wide range of annoriented applications for forecasting are given in the literature. these are classified into five groups:(1) anns in short-term lf, (2) anns in mid-term lf, (3) anns in long-term lf, (4) hybrid anns inlf,...
