An Hypothalamic Hamartoma Presenting as Gelastic Epilepsy: When it Goes Unnoticed

A 5-year-old boy presented with episodes of ocular retroversion occurring over the past 4 weeks. Further investigation revealed frequent bilateral epileptiform frontal activity on electroencephalogram and a nodular formation in the hypothalamus on cerebral computed tomography scan. Magnetic resonance imaging characterized the lesion as a hamartoma of the tuber cinereum. After questioning, episodes of unprovoked...

A Reflection on Three Decades of Journalism Teaching at the Faculty of Arts and...

The 30th anniversary of the Journalism course at the Faculty of Arts and Humanities of the University of Coimbra (FLUC), whose main founder was the former journalist and politician Mário Mesquita (Peixinho, 2023), was also the 50th anniversary of the Portuguese Carnation Revolution. In this context, it is urgent to reflect on the academic training of journalists and communication professionals (Peixinho, 2016) ...

Understanding the ecological consequences of deep-sea mining: cadmium’s influen...

Background: Metal-rich nodules in the deep ocean contain significant quantities of high-value metals such as copper, nickel, and cobalt [1]. Mining deep-sea minerals is considered as an alternative to land mining, to reduce environmental effects and gain geopolitical advantages [1,2]. However, this action may expose deep-sea microbes to toxic concentrations of metals such as cadmium (Cd) which are shown to have...

Castro de Guifões (Northwest Portugal) during Late Antiquity: perspectives on a...

This study examines the archaeological and anthracological findings from Castro de Guifões in Northwest Portugal, focusing on its significance during Late Antiquity. Strategically located by the River Leça, the settlement served as a hub of trade, facilitating connections between diverse communities through land and maritime routes. Evidence suggests it functioned as an ancient docking harbor, characterized by ...

Tooth Luxation as the First Clue to an Epilepsy Diagnosis

A Cobertura Mediática da Morte de Ihor Homenyuk

A morte de Ihor Homenyuk não invadiu as manchetes dos jornais portugueses. A pandemia era o tema central do espaço público, que tornava a agenda mediática praticamente monotemática (Lopes et al., 2021). Desta forma, o presente estudo pretende debruçar-se sobre a cobertura que dois dos principais jornais de referência nacionais, Expresso e Público, fizeram do caso em dois períodos fulcrais: 28 de março a 11 de a...

Cadmium effects on net N2O production by the deep-sea isolate Shewanella loihic...

Deep-sea mining may lead to the release of high concentrations of metals into the surrounding seabed, which can disturb important ecosystem functions provided by microbial communities. Among these, the production of N2O and its reduction to N2 is of great relevance since N2O is an important greenhouse gas. Metal impacts on net N2O production by deep-sea bacteria are, however, currently unexplored. Here, we eval...

The impact of psychostimulants on central and peripheral neuro-immune regulatio...

It is now well-accepted that psychostimulants act on glial cells causing neuroinflammation and adding to the neurotoxic effects of such substances. Neuroinflammation can be described as an inflammatory response, within the CNS, mediated through several cytokines, reactive oxygen species, chemokines and other inflammatory markers. These inflammatory players, in particular cytokines, play important roles. Several...

Mapping human pathogens in wastewater using a metatranscriptomic approach

The monitoring of cities' wastewaters for the detection of potentially pathogenic viruses and bacteria has been considered a priority during the COVID-19 pandemic to monitor public health in urban environments. The methodological approaches frequently used for this purpose include deoxyribonucleic acid (DNA)/Ribonucleic acid (RNA) isolation followed by quantitative polymerase chain reaction (qPCR) and reverse t...

Language regression as a manifestation of epilepsy

Introduction: Childhood epileptic encephalopathies are age-dependent brain disorders in which ictal and interictal epileptogenic activity is the apparent cause of progressive cognitive and neuro-psychological impairment. Case report: A previously healthy four-year-old boy presented to the Emergency Department with a history of receptive and expressive language regression with four days of evolution, associated ...
