Os edifícios de espetáculo em Conimbriga. Problemáticas e desafios.
Dias, Vítor; Correia, Virgílio Hipólito; Ruivo, José; Silva, Ricardo Costeira; Ferreira, FilipeNos últimos anos, o desenvolvimento da investigação arqueológica com recurso a novas metodologias e abordagens interpretativas de edifícios e estruturas cuja funcionalidade é há muito discutida, motivou uma reflexão sobre a possibilidade da existência de um quarteirão lúdico no Vale Norte de Conimbriga. À existência, já confirmada, de um anfiteatro vem, agora, equacionar- se a possibilidade da presença de um ed...
Comparative study of humoral and cellular immunity against SARS-CoV-2 induced b...
Hasan, Zahra; Masood, Kiran Iqbal; Qaiser, Shama; Kanji, Akbar; Mwenda, Fridah; Alenquer, Marta; Iqbal, Junaid; Ferreira, Filipe; Wassan, YaqubWe investigated the effectiveness of different COVID-19 vaccinations administered in Pakistan by studying the effect of inactivated virus, mRNA and vector formulations. This study in 916 participants was conducted between October 2021 and July 2022. Subjects receiving inactivated (A), mRNA (B), one-dose vector (C), and two-dose vector (D) vaccines were sampled at baseline, 6, 12, and 24 weeks. Serum IgG antibod...
The effects of post-warm-up active and passive rest periods on a vigilance task...
Silva, Rui Miguel; González-Fernández, Francisco; Rusillo-Magdaleno, Alba; Pires, Dinis; Ferreira, Filipe; Silva, Ana Filipa; Loureiro, VâniaThis study aimed to analyze how active versus passive rest periods after a warm-up influence performance in psychomotor vigilance tasks (PVT). Twenty amateur karate athletes participated in a randomized cross-over study consisting of two sessions with either a 20 min active rest involving kata techniques or passive rest. PVT was administered before and after these conditions to assess the changes in reaction ti...

Rapport d’activité – Projet LUDERE – Le quartier des spectacles de la ville de ...
Ferreira, FilipeLe projet LUDERE a pour objectif d’étudier l’évolution urbaine de la partie septentrionale du vale norte, correspondant au quartier de l’amphithéâtre de la ville antique de Conimbriga (Condeixa-a-Velha, Portugal). L’étude du bâti a permis de mettre en évidence la chronologie relative des maçonneries. Au viaduc premièrement construit, succèdent plusieurs maçonneries venant s’y adosser pour en renforcer la stabil...
Defining basic rules for hardening influenza A virus liquid condensates
Etibor, Temitope Akhigbe; Vale-Costa, Silvia; Sridharan, Sindhuja; Brás, Daniela; Becher, Isabelle; Mello, Victor Hugo; Ferreira, FilipeIn biological systems, liquid and solid-like biomolecular condensates may contain the same molecules but their behaviour, including movement, elasticity and viscosity, is different on account of distinct physicochemical properties. As such, it is known that phase transitions affect the function of biological condensates and that material properties can be tuned by several factors including temperature, concentr...
Balance between maternal antiviral response and placental transfer of protectio...
Gonçalves, Juliana; Melro, Magda; Alenquer, Marta; Araújo, Catarina; Castro-Neves, Júlia; Amaral-Silva, Daniela; Ferreira, Filipe; Ramalho, José S.The intricate interplay between maternal immune response to SARS-CoV-2 and the transfer of protective factors to the fetus remains unclear. By analyzing mother-neonate dyads from second and third trimester SARS-CoV-2 infections, our study shows that neutralizing antibodies (NAbs) are infrequently detected in cord blood. We uncovered that this is due to impaired IgG-NAb placental transfer in symptomatic infectio...
Towards the purification of IgY from egg yolk by centrifugal partition chromato...
Almeida, Mafalda R.; Ferreira, Filipe; Domingues, Pedro dimas; Coutinho, João A. P.; Freire, Mara G.Although their high potential as alternative biopharmaceuticals, less than 2% of the total polyclonal antibodies produced worldwide correspond to immunoglobulin Y (IgY) due to the difficulties in isolating them from egg yolk (complex biological matrix). In this work, the water-soluble proteins fraction (WSPF) of egg yolk was first obtained and the proteins present identified by one-dimensional gel electrophores...
Experiences of informal care to the person with dyspnea at home
Ferreira, Filipe; Barreira, EsmeraldaDyspnoea affects life quality of the patient and its family due to the impairment of communication and every day activities, anxiety and even panic. Most patients with cancer suffer dyspnoea episodes resulting from the primary disease, metastasis or even from treatment. During these phases, patients at home need informal caregivers to assist then in their activities. Thepresent descriptive exploratory study, in...
Simulation study of SARS-CoV-2 (COVID-19) by breathing, coughing and sneezing
Ferreira, Filipe; Catarino, Susana Oliveira[Excerpt] Introduction: According to the World Health Organization, 11 months after the first reported case, the SARS-CoV2 (COVID-19) pandemic has infected more than 40 million people worldwide, with a mortality rate around 2,8 % [1]. The scientific community recognized transmission by airborne particles as the primary route of infection. These particles can be distinguished in droplets, with diameter > 10 - 20...
