Gender, sex and sexuality in two open access communication journals published in Portugal: a critical overview of current discursive practices

The links between gender, sex and sexuality and their relevance are theoretically and politically problematic (Richardson, 2007). One of the difficulties in understanding their interconnections is that these terms are often used differently and ambiguously by different authors (and even by the same authors). This article reports the results of an analysis of the articles published in open access communication journals with known impact factor, edited in Portugal and published between 2005 and 2012. The diverse conceptualisations of those three basic concepts and of their (inter)relationships within communication research are identified. The complexity and the intricate (and often implicit) nature of both the meanings of these categories and their relationships underlie and justify our attention and further research. What the findings suggest about the current communication research into gender issues published in the two journals surveyed is that the ‘Gender differences discourse’ (Sunderland, 2004) is the most pervasive discourse (also) in academic practice. Additionally, they show that gender and sex are mainly taken for a fact, not a question that is worth being studied. The editors of these journals, as well as the scholars submitting manuscripts, need to be more aware of the traditional nature of the theoretical and methodological choices that they make regarding gender- and sex-related issues, as well as of the relative lack of attention to sexuality as a research subject.

Mesenchymal stem cells secretome as a modulator of the neurogenic niche: Basic insights and therapeutic opportunities

Neural stem cells (NSCs) and mesenchymal stem cells (MSCs) share few characteristics apart from self-renewal and multipotency. In fact, the neurogenic and osteogenic stem cell niches derive from two distinct embryonary structures; while the later originates from the mesoderm, as all the connective tissues do, the first derives from the ectoderm. Therefore, it is highly unlikely that stem cells isolated from one niche could form terminally differentiated cells from the other. Additionally, these two niches are associated to tissues/systems (e.g., bone and central nervous system) that have markedly different needs and display diverse functions within the human body. Nevertheless they do share common features. For instance, the differentiation of both NSCs and MSCs is intimately associated with the bone morphogenetic protein family. Moreover, both NSCs and MSCs secrete a panel of common growth factors, such as nerve growth factor (NGF), glial derived neurotrophic factor (GDNF), and brain derived neurotrophic factor (BDNF), among others. But it is not the features they share but the interaction between them that seem most important, and worth exploring; namely, it has already been shown that there are mutually beneficially effects when these cell types are co-cultured in vitro. In fact the use of MSCs, and their secretome, become a strong candidate to be used as a therapeutic tool for CNS applications, namely by triggering the endogenous proliferation and differentiation of neural progenitors, among other mechanisms. Quite interestingly it was recently revealed that MSCs could be found in the human brain, in the vicinity of capillaries. In the present review we highlight how MSCs and NSCs in the neurogenic niches interact. Furthermore, we propose directions on this field and explore the future therapeutic possibilities that may arise from the combination/interaction of MSCs and NSCs.

Portugal: Postdoc rights need not hurt productivity

[Excerpt] Portugal’s government is on the verge of a historic process, recognizing at last that postdoctoral researchers should have the same rights as the rest of the country’s workforce (see go.nature.com/famkkn; in Portuguese). In defiance of European Union practice, more than 90% of these early-career scientists are currrently classed as ‘advanced students’ and funded by student scholarships. (...)

Prevalência e preditores de sintomatologia depressiva após o parto

Contexto: A depressão pós-parto é uma patologia que ocorre nas primeiras semanas após o parto com conseqüências negativas não só para a mãe, como também para o bebê e para a família. Objetivo: Examinar a prevalência de depressão após o parto, bem como as circunstâncias suscetíveis de predizer a sintomatologia depressiva 1 semana e 3 meses após o parto. Métodos: 197 grávidas preencheram o Questionário de Antecipação do Parto (QAP) (Costa et al., 2005a) no segundo trimestre de gestação. Na primeira semana após o parto, responderam ao Questionário de Experiência e Satisfação com o Parto (QESP) (Costa et al., 2005b) e à Edinburgh Postnatal Depression Scale (EPDS) (Augusto et al., 1996), esta última aplicada novamente no terceiro mês do puerpério. Resultados: Uma percentagem significativa de mulheres encontra-se clinicamente deprimida (EPDS ≥ 13) na primeira semana e 3 meses após o parto (12,4% e 13,7%, respectivamente). Das que têm EPDS ≥ 13 na primeira semana, 25% estão ainda deprimidas 3 meses após o parto. Circunstâncias relativas à saúde física, à experiência emocional de parto e ao primeiro contato com o bebê predizem a sintomatologia depressiva na primeira semana do puerpério. A sintomatologia depressiva na primeira semana após o parto e a experiência emocional negativa de parto predizem a sintomatologia depressiva 3 meses após o parto. Conclusões: Constata-se a importância da experiência emocional de parto e do primeiro contato com o bebê, enfatizando a necessidade de atender às necessidades psicológicas da mulher.
