Bioquímica e ação citotóxica de alfa-aminocetonas endógenas

alpha-Aminoketones are expected to undergo enolization and subsequent aerobic oxidation yielding oxyradicals and highly toxic a-oxoaldehydes. Our interest has been focused on two endogenous a-aminoketones: 5-aminolevulinic acid (ALA) and aminoacetone (AA), accumulated in porphyrias and diabetes mellitus, respectively, and recently implicated as contributing sources of oxyradicals in these diseases. The final oxidation product of ALA, 4,5-dioxovaleric acid (DOVA), is able to alkylate DNA guanine moieties and expected to promote protein cross-linking. Methylglyoxal (MG), the final oxidation product of AA, is also highly cytotoxic and able to aggregate protein molecules. This review covers chemical and biochemical aspects of these alpha-aminoketones and their putative roles in the oxidative stress associated with porphyric disorders and diabetes.

Factors associated with active aging in Finland, Poland, and Spain

BACKGROUND: Continuous population aging has raised international policy interest in promoting active aging (AA). AA theoretical models have been defined from a biomedical or a psychosocial perspective. These models may be expanded including components suggested by lay individuals. This paper aims to study the correlates of AA in three European countries, namely, Spain, Poland, and Finland using four different definitions of AA. METHODS: The EU COURAGE in Europe project was a cross-sectional general adult population survey conducted in a representative sample of the noninstitutionalized population of Finland, Poland, and Spain. Participants (10,800) lived in the community. This analysis focuses on individuals aged 50 years old and over (7,987). Four definitions (two biomedical, one psychosocial, and a complete definition including biomedical, psychosocial, and external variables) of AA were analyzed. RESULTS: Differences in AA were found for country, age, education, and occupation. Finland scored consistently the highest in AA followed by Spain and Poland. Younger age was associated with higher AA. Higher education and occupation was associated with AA. Being married or cohabiting was associated with better AA compared to being widowed or separated in most definitions. Gender and urbanicity were not associated with AA, with few exceptions. Men scored higher in AA only in Spain, whereas there was no gender association in the other two countries. Being widowed was only associated with lower AA in Poland and not being married was associated with lower AA in Poland and Finland but not Spain. CONCLUSIONS: Associations with education, marital status, and occupation suggest that these factors are the most important components of AA. These association patterns, however, seem to vary across the three countries. Actions to promote AA in these countries may be addressed at reducing inequalities in occupation and education or directly tackling the components of AA lacking in each country.

Les TIC aplicades a la història de la infermeria

La cerca d'informació i el pensament crític són competències transversals que es consideren bàsiques per als estudiants universitaris. Aquestes dues competències s'han pogut desenvolupar en el marc d'una activitat denominada cerca i lectura crítica de documents històrics, que es va incloure dins dels crèdits pràctics de l'assignatura Història de la Professió. Les tasques consistien a fer una cerca bibliogràfica a través de les bases de dades més habituals per la Infermeria, obtenir un document històric, fer-ne una lectura crítica i confeccionar un informe escrit. Presentem l'activitat que es va oferir a tots els alumnes de segon semestre d'Infermeria (grups M6 T6), la seva metodologia i els resultats de la seva implementació, que mostren un grau molt elevat de satisfacció en l'alumnat i la seva utilitat en el foment de la lectura crítica.

Design and evaluation of a continuous flow, integrated nebulizer-hydride generator for flame atomic absorption spectrometry

An evaluation of the performance of a continuous flow hydride generator-nebulizer for flame atomic absorption spectrometry was carried out. Optimization of nebulizer gas flow rate, sample acid concentration, sample and tetrahydroborate uptake rates and reductant concentration, on the As and Se absorbance signals was carried out. A hydrogen-argon flame was used. An improvement of the analytical sensitivity relative to the conventional bead nebulizer used in flame AA was obtained (2 (As) and 4.8 (Se) µg L-1). Detection limits (3σb) of 1 (As) and 1.3 (Se) µg L-1 were obtained. Accuracy of the method was checked by analyzing an oyster tissue reference material.
