This study was designed to assess the prevalence of adverse drug reactions (ADRs) in the internal medicine wards of two teaching Hospitals, identify the most common ADRs, the principal medications involved, and determine the risk factors implicated in the occurrence of such ADRs. All admissions over 10 weeks were followed prospectively using an intensive(More)
A quantitative structure-activity study to evaluate the effect of lipophilia/aqueous solubility on etiolated wheat coleoptiles elongation has been carried out with 34 guaianolides having different numbers of hydroxyl groups and ester side chains of variable length and structure: linear, branched, aromatic, and unsaturated. Compounds have been tested in a(More)
A structure-activity study to evaluate the effect of the trans, trans-germacranolide sesquiterpene lactones costunolide, parthenolide, and their 1,10-epoxy and 11,13-dihydro derivatives (in a range of 100-0.001 microM) on the growth and germination of several mono and dicotyledon target species is accomplished. Results are compared with those obtained in(More)
A structure-activity study to evaluate the effect of 17 guaianolide sesquiterpene lactones (in a range of 100-0.001 microM) on the growth and germination of several mono- and dicotyledon target species is accomplished. Results are compared with those obtained in the same bioassay with an internal standard, the commercial herbicide Logran, to validate the(More)
INTRODUCTION Transient global amnesia (TGA) is characterised by impairment of anterograde memory and, to a certain extent, retrograde memory, which is associated with mild temporal and spatial disorientation that is completely re-established after a few hours. There are different hypotheses about its pathogenesis, including theories about a possible(More)
