OBJECTIVE Approximately 25% of all general dentists practicing in the United States use a computer in the dental operatory. Only 1.8% maintain completely electronic records. Anecdotal evidence suggests that dental computer-based patient records (CPR) do not represent clinical information with the same degree of completeness and fidelity as paper records.(More)
Amaranthus leucocarpus lectin is a homodimeric glycoprotein of 35 kDa per sub-unit, which interacts specifically with N-acetyl-galactosamine. In this work, we compared different glycoproteins that contain Galbeta1-3 GalNAcalpha1-3 Ser/Thr or GalNAcalpha1-3 Ser/Thr in their structure as ligands to purify the A. leucocarpus lectin. From the glycoproteins(More)
In this work we characterized a 90-kDa glycoprotein from Alzheimer disease (9OAzgp) brain extracts that is recognized by the GalNAc-specific lectin from Amaranthus leucocarpus (ALL), as determined through Western blot. The 90Azgp was purified by electro-elution, and its amino acid sequence determined from peptides obtained after trypsin digestion through(More)
The university is currently immersed-within Europe-in a process of coordinating higher education with the adaptation into the new ECTS European credits, which implies changing from a teacher-centred model (teacher conveys knowledge) to a learner-centred model, a real challenge. From 1996, the Universitat Autònoma de Barcelona (UAB) is carrying out the "(More)
BACKGROUND Patients with metabolic syndrome (MS) often have increased platelet aggregation. In order to determine which concentration detects a higher level of platelet aggregation in patients with MS, the agonists ADP and epinephrine were compared. METHODS The study included 56 subjects with MS and 53 healthy subjects. Blood pressure, weight, body-mass(More)
OBJECTIVE Develop and validate an initial content taxonomy for patient records in general dentistry. METHODS Phase 1 - obtain 95 de-identified patient records from 11 general dentists in the United States. Phase 2 - extract individual data fields (information items), both explicit (labeled) and implicit (unlabeled), from records, and organize into(More)
Fibroadenomas are benign human breast tumors, characterized by proliferation of epithelial and stromal components of the terminal ductal unit. They may grow, regress or remain unchanged, as the hormonal environment of the patient changes. Expression of antigen TF in mucin or mucin-type glycoproteins and of galectin-3 seems to contribute to proliferation and(More)
The ability of acute environmental or intraperitoneal (i.p.) ethanol to influence morphine antinociceptive effect was studied in mice. In order to induce tolerance to morphine analgesia, mice received daily injections of 10 mg/Kg morphine over a period of 10 days. Mice were divided into three groups: i.p. ethanol (E), environmental ethanol (E*), and control(More)
