Transcription factor, cAMP response element-binding protein (CREB), which is phosphorylated by cAMP-dependent kinase via an increase in cAMP, and regulates gene transcription by binding to the cAMP response element (CRE) on target genes. We examined age-dependent alterations in the DNA-binding activity of CREB in rat brain regions, and the effects of(More)
To evaluate the long-term safety of Pegvisomant (PEG) in the Spanish cohort of ACROSTUDY. As of July 2013, 199 Spanish patients were included in ACROSTUDY, a global non interventional safety PEG surveillance study. Patients were observed for safety, biochemical outcome and magnetic resonance imaging evaluations. PEG was administered during an average period(More)
Braille reading is a demanding task that requires the identification of rapidly varying tactile patterns. During proficient reading, neighboring characters impact the fingertip at ∼100 ms intervals, and adjacent raised dots within a character at 50 ms intervals. Because the brain requires time to interpret afferent sensorineural activity, among other(More)
Sixty-seven digoxin-containing sera were analyzed by both radioimmunoassay and EMIT. After some important modifications of the EMIT method, agreement between the two methods was very good. Reproducibility of the EMIT assay was excellent; daily variations in values found for control sera were quite small, and recovery of added digoxin was good. Slight(More)
fluoride tubes, the absolute insulin values would be incorrect. The fact that blood collected in an oxalate-fluoride tube is more severely hemolyzed is emphasized by the data in Figure 1 and Table 2. In the comparison of insulin and hemoglobin levels in two different plasma tubes, it is obvious that samples collected in tubes containing EDTA are more(More)
A new capillary zone electrophoresis (CZE) method for the determination of tacrine (THA), 7-methoxytacrine (7-MTHA) and their basic metabolites (THAm, 7-MTHAm) in pharmaceutical and biological samples (urine and serum) was developed. Separation of all compounds by CZE was carried out using a 46.6 cm untreated fused-silica capillary applying 20 kV separation(More)
