Avaliacao das condicoes de saude bucal dos idosos em um municipio brasileiro

This study assessed the oral health of individuals 60 years or older in the city of Araraquara, Sao Paulo, Brazil, in 1998. Of the 194 people who participated in the study, 91 of them were institutionalized and had an average age of 73.6 years, and 103 were not institutionalized and had an average age of 69.3 years. The study participants were examined by a previously trained oral surgeon who determined the prevalence of the most common oral health problems. The results revealed a large number of edentulous individuals (72% of those institutionalized and 60% of the noninstitutionalized participants) and many persons with extracted teeth (93% and 90%, respectively), as well as a high frequency of periodontal pockets (57% and 75%, respectively) and of inadequate dentures (80% and 61%, respectively). Our results show reduced quality of life for a large proportion of these older individuals, and also indicate that public health services should pay greater attention to this population group.

ZmPUMP encodes a fully functional monocot plant uncoupling mitochondrial protein whose affinity to fatty acid is increased with the introduction of a His pair at the second matrix loop

Uncoupling proteins (UCPs) are specialized mitochondrial transporter proteins that uncouple respiration from ATP synthesis. In this study, cDNA encoding maize uncoupling protein (ZmPUMP) was expressed in Escherichia coli and recombinant ZmPUMP reconstituted in liposomes. ZmPUMP activity was associated with a linoleic acid (LA)-mediated H+ efflux with Km of 56.36 ± 0.27 μM and Vmax of 66.9 μmol H+ min-1 (mg prot)-1. LA-mediated H+ fluxes were sensitive to ATP inhibition with Ki of 2.61 ± 0.36 mM (at pH 7.2), a value similar to those for dicot UCPs. ZmPUMP was also used to investigate the importance of a histidine pair present in the second matrix loop of mammalian UCP1 and absent in plant UCPs. ZmPUMP with introduced His pair (Lys155His and Ala157His) displayed a 1.55-fold increase in LA-affinity while its activity remained unchanged. Our data indicate conserved properties of plant UCPs and suggest an enhancing but not essential role of the histidine pair in proton transport mechanism. © 2006 Elsevier Inc. All rights reserved.
