The oestrogen receptor content of colorectal adenocarcinoma was investigated using an established ligand binding biochemical assay and two more recently introduced techniques using specific monoclonal antibodies (Abbott ER-EIA and ER-ICA assay kits). Twenty nine tumours were investigated by the ligand binding assay. Only one (3.4%) tumour gave a weakly positive result (11 fmol/mg cytosol protei...

Background: Internal carotid artery (ICA) dissection is one of the most common causes stroke in young patients. Ultrasonographic assessment method choice for early detection. The use conventional technique diagnosis limited since frequently occurs distal portion ICA. Case Report: We describe case a 48-year-old Argentinian woman with malignant cerebral infarction secondary to ICA dissection. dia...

background: role of atherosclerosis  in the pathogenesis of ischemic and hemorrhagic  infarctions is still matter  of debate. intima-media thickness (imt) of the common carotid  artery (cca) and  internal  carotid  artery (ica) are markers of atherosclerosis. the aim of this study was to compare  cca imt and ica imt of patients  with ischemic and hemorrhagic infarction. methods: two equal group...

Urocortin (UCN) II, a newly isolated corticotropinreleasing- factor (CRF) related peptide, has been found to have potent cardiovascular protective effects. To investigate the mechanisms of its vascular protective effects, we exposed mesenteric arterial smooth muscle cells (MASMC) from spontaneously hypertensive rats (SHR) to UCN II to observe the change in cell apoptosis using TUNEL assay and m...

The detection of transient events related to slow earthquakes in GNSS positional time series is key understanding seismogenic processes subduction zones. Here, we present a novel Principal and Independent Components Correlation Analysis (PICCA) method that allows for the temporal spatial signals. PICCA based on an optimal combination principal (PCA) independent component analysis (ICA) network....

This thesis is about convolutive ICA with application to EEG. Two methods for convolutive ICA are proposed. One method, the CICAP algorithm, uses a linear predictor in order to formulate the convolutive ICA problem in two steps: linear deconvolution followed by instantaneous ICA. The other method, the CICAAR algorithm, generalizes Infomax ICA to include the case of convolutive mixing. One advan...

Diabetes deteriorates atherosclerotic changes in the arteries. The aim of the study was to assess the prevalence and localization of stenotic atherosclerotic lesions of the internal carotid artery (ICA) in patients with diabetes. A prospective analysis of angiography findings was carried out in 150 diabetic and 150 non-diabetic patients with symptoms of cerebral ischemia using double-blind angi...
