Reestruturação produtiva e condições sociais
Este artigo aborda a reestruturação produtiva que marcou o Brasil nos anos 90, analisando os seus efeitos sociais. Reconhecendo como essa reestruturação está associada à inserção do país na dinâmica da economia globalizada e à implementação de um conjunto de políticas recomendadas pelos organismos multilaterais, o texto assinala como as transformações decorrentes dessas políticas vêm se traduzindo em, a) baixos níveis de crescimento econômico; b) uma deterioração das condições de trabalho e renda da maioria da população; c) uma acentuação das desigualdades sociais e espaciais ;e d) uma reorientação profunda e regressiva das políticas e do sistema de proteção social
Occurrence of microsporidians Glugea hertwigi and Pleistophora ladogensis, in smelt Osmerus eperlanus from two German rivers, North Sea coast
Monthly samples of smelt Osmerus eperlanus (Linnaeus, 1758) were collected from
July 1985 to May 1986, in the river Elbe (Germany), and examined for infections with microsporidi ans. Two microsporidians were found: Glugea hertwigi Weissenberg, 1911, infecting the digestive
tract and Pleistophora ladogenis Voronin, 1978, infecting the skeletal musculature. G. hertwigi in fection led to the formation of xenomas, whereas P. ladogensis was characterized by diffuse infec tions, with the production of macroscopic visible thread-like or oval-shaped infection foci. Develop ment of G. hertwigi in the host cells showed characteristics typical of the genus Glugea. The
ultrastructural development of P. ladogensis showed features typical of the genus Pleistophora,
without evidence of the production of 2 types of spores. Host reaction consisted of inflammatory tis sue surrounding some of the infection foci as well as phagocytosis of spores. G. hertwigi was only
found in juvenile smelt (<10 cm in length), whereas P. ladogensis infected smelts from 6 to 26 cm in
length. Prevalence increased with fish length to a maximum value of 9.6%. Seasonal fluctuations in
prevalence of infection were also found, with the lowest value in the winter months (2.5% in
January 1986) and the highest in summer (11.8% in July 1985). The differences in prevalence of in fection with fish length and date of sampling were significant. Additionally, samples of smelt caught
in April 1986 from the rivers Eider and Ems revealed infections with P. ladogensis in the first river

Multidimensional Health Impact of Multicomponent Exercise and Sustainable Healthy Diet Interventions in the Elderly (MED-E): Study Protocol
Data concerning the combined effect of diet and exercise interventions on overall health in the elderly are scarce. The MED-E project's primary aim is to assess the effect of the different 3-month sustainable healthy diet (SHD) and multicomponent training (MT) interventions on several health outcomes in the elderly. A quasi-experimental study assigned older adults into four groups: (1) SHD, (2) MT, (3) SHD + MT, or (4) control group (CG). The SHD intervention included a weekly offer of a mixed food supply and individual and group nutritional sessions on the principles of an SHD. The MT groups were submitted to 50-min exercise sessions three times a week. The primary outcomes were blood biomarkers and metabolic profile alterations that were assessed pre- and post-intervention. Additionally, data on dietary intake and nutritional adequacy, physical fitness, body composition and anthropometry, cognitive function, quality of life, and geographical data were assessed at the same time points. The MED-E project's study protocol and future results will add to knowledge about the importance and beneficial contribution of combined SHD and MT interventions on healthy ageing policies
