This paper presents some results of the project (H)ISTO é MATEMÁTICA — História da Matemática no Ensino da Matemática (History of Mathematics in teaching), a research project that has as one of its main goals: to describe the initial and continuous training of Portuguese teachers in History of Mathematics (HM), as well as their conceptions and practices on the use of HM in teaching. In particular, we present th...
O humor tem larga presença na vida das pessoas, combinando elementos afetivos e cognitivos com o intuito de bem-dispor. Para além dos contextos de lazer, o humor tem também sido utilizado em contextos associados ao trabalho, nomeadamente nas escolas, colocado ao serviço do ensino. Sendo os manuais escolares um recurso muito utilizado pelos professores, particularmente pelos de Matemática, pareceu-nos pertinente...
The production of pork with moderate amounts of intramuscular fat (IMF) without an increase in subcutaneous fat is highly desirable for the meat industry. Several studies indicate that dietary protein reduction during the growing-finishing period of pigs enhances IMF content, but its consequence on carcass fat deposition is still contradictory. In this study, we hypothesized that the effects of reduced protein ...

In the meat industry, the manipulation of fat deposition in cattle is of pivotal importance to improve production efficiency, carcass composition and ultimately meat quality. There is an increasing interest in the identification of key factors and molecular mechanisms responsible for the development of specific fat depots. This study aimed at elucidating the influence of breed and diet on adipose tissue membran...
Este trabalho pretende dar sequência a um estudo anteriormente realizado na Escola de Saúde Pública ERISA, onde se concluiu que a maioria dos inquiridos nunca sentiu ou desconhece ter sentido reacções adversas associadas a medicamentos à base de plantas medicinais. Segundo o referido estudo, os produtos à base de plantas são procurados como medicamentos maioritariamente por mulheres, em particular as estudantes...
Gastric cancer remains a major cause of death in the developed countries, and a large percentage is still genetically unexplained. Because of their major role in cell survival, mutations in translation factors and altered expression of these genes have been associated with cancer development. Apart from its role in translation termination, the eukaryotic translation release factor 3 (eRF3) is involved in severa...
Background: There are now several lines of evidence to suggest that protein synthesis and translation factors are involved in the regulation of cell proliferation and cancer development. Aims: To investigate gene expression patterns of eukaryotic releasing factor 3 (eRF3) in gastric cancer. Methods: RNA was prepared from 25 gastric tumour biopsies and adjacent non-neoplastic mucosa. Real time TaqMan reverse tra...
The essential oils from Piper capense, P. nigrum, P. guineense and P. umbellatum from S. Tomé e Príncipe were investigated for the first time. They were analysed by GC, GC-mass spectrometry and 13C NMR. Monoterpene hydrocarbons were the main group of constituents in three of the samples (P. capense, P. nigrum and P. umbellatum), whereas for the other species (P. guineense) phenylpropanoid derivatives were the m...
