Nickel aluminum bronzes (NAB) are corrosion resistant alloys used in seawater environments as parts of valves, fittings, ship propellers, pumps, pump shafts, and heat exchangers. As many other alloys, NAB can be cast or wrought. More recently, additive manufacture methods have been studied for this class of materials. Corrosion problems are reported in the literature, and are related to the presence of β phase, de-alloying and low aluminum content. In this work, the mechanical behaviour of a cast ...

The coronavirus disease 2019 pandemic (COVID-19) has an important direct and indirect impact on both physical and mental health. We aim to describe the impact of an emergency state period due to COVID-19 on psychiatric emergency department (ED) visits. We conducted a retrospective observational study analysing all emergency visits occurring at a metropolitan psychiatric ED between March 19th and May 2nd 2019 and 2020 (the beginning/end date of the emergency state which Portugal was under due to COVID- ...

Oxidative stress and abnormal DNA methylation have been implicated in cancer, including myelodysplastic syndromes (MDSs). This fact leads us to investigate whether oxidative stress is correlated with localized and global DNA methylations in the peripheral blood of MDS patients. Sixty-six MDS patients and 26 healthy individuals were analyzed. Several oxidative stress and macromolecule damage parameters were analyzed. Localized (gene promotor) and global DNA methylations (5-mC and 5-hmC levels; LINE- ...

Dipeptidyl peptidase IV, a cell membrane surface protease also known as CD26 (CD26/DPPIV), is known to play multiple functions in human organism, where it is largely expressed, for instance, in the development of human cancer and metastasis as well as in chemotherapy response. The objective of this work was to study the CD26 membrane expression and DPPIV activity in T-acute leukaemia cell lines (CEM and MOLT3) in culture, in order to observe the modification of its expression under the 8-azaguanine ...

Co-cultures of Pinus pinaster with Bursaphelenchus xylophilus were established as a biotechnological tool to evaluate the effect of nematotoxics addition in a host/parasite culture system. The pinewood nematode (PWN), Bursaphelenchus xylophilus, the causal agent of pine wilt disease (PWD), was detected for the first time in Europe in 1999 spreading throughout the pine forests in Portugal and recently in Spain. Plant in vitro cultures may be a useful experimental system to investigate the plant/nematode ...

Summary The pinewood nematode ( PWN ), B ursaphelenchus xylophilus , is a serious quarantine pest first detected in P ortugal and E urope in 1999. It is the causal agent of pine wilt disease ( PWD ). A resistance breeding programme has been initiated to contribute to control the evolution of the disease. Five hundred and four adult maritime pine, P inus pinaster , trees were phenotypically selected as candidate trees for this programme from an area affected by PWD . To identify tolerance to the nematode, the selected ...

The research on porous materials for the selective capture of fluorinated gases (F-gases) is key to reduce their emissions. Here, the adsorption of difluoromethane (R-32), pentafluoroethane (R-125), and 1,1,1,2-tetrafluoroethane (R-134a) is studied in four metal-organic frameworks (MOFs: Cu-benzene-1,3,5-tricarboxylate, zeolitic imidazolate framework-8, MOF-177, and MIL-53(Al)) and in one zeolite (ZSM-5) with the aim to develop technologies for the efficient capture and separation of high global warming ...

Abstract Background The increasing awareness of the release of fluorinated gases (F‐gases) into the atmosphere is instigating the development of techniques to capture them from refrigerants. In this work, the adsorption of difluoromethane (R‐32), pentafluoroethane (R‐125), and 1,1,1,2‐tetrafluoroethane (R‐134a) on four different activated carbons (ACs) is studied. Additionally, the selectivity of the ACs for the components of commercial refrigerants, R‐410A and R‐407F, is evaluated. Results The estimation ...

Introduction Hyponatremia is a common electrolyte alteration which has the potential for significant morbidity and mortality. Endocrine disorders, such as primary hypothyroidism and adrenal insufficiency are uncommon causes of hyponatremia. We present the case of a teenager with symptomatic hyponatremia caused by a rare disorder. Case A 17-year-old boy was admitted to the emergency department with abdominal pain, nausea and vomiting, asthenia, and weight loss. He was in poor general condition, hypotensive, ...

Alkaline phosphatase (ALP) is important in calcification and its expression seems to be associated with the inflammatory process. We investigated the in vitro acute effects of compounds used for the prevention or treatment of cardiovascular diseases on total ALP activity from male Wistar rat heart homogenate. ALP activity was determined by quantifying, at 410 nm, the p-nitrophenol released from p-nitrophenylphosphate (substrate in Tris buffer, pH 10.4). Using specific inhibitors of ALP activity and ...

ABSTRACT BACKGROUND Research on relationships between lifestyle behaviors and adiposity in school youth is potentially important for identifying subgroups at risk. This study evaluates the associations between waist circumference ( WC ) and objective measures of sedentary behavior ( SB ) in a sample of rural school adolescents. METHODS The sample included 254 students (114 boys, 140 girls), 13‐16 years of age, from rural regions of the Portuguese midlands. Height, weight, and WC were measured. Cardiorespiratory ...

O ambiente estuarino é altamente complexo e produtivo, além de ser um dos principais meios de subsistência para populações costeiras e ribeirinhas. Apesar de sua relevância ecológica, econômica e social, esse ecossistema vem sofrendo forte exploração antrópica, principalmente através da urbanização e do descarte de efluentes. Diante dessa situação, o presente estudo procurou avaliar a evolução das condições ambientais do estuário do rio Timbó, através da análise da clorofila a e das variáveis físico- ...

The 'day residue' - the presence of waking memories into dreams - is a century-old concept that remains controversial in neuroscience. Even at the psychological level, it remains unclear how waking imagery cedes into dreams. Are visual and affective residues enhanced, modified, or erased at sleep onset? Are they linked, or dissociated? What are the neural correlates of these transformations? To address these questions we combined quantitative semantics, sleep EEG markers, visual stimulation, and multiple ...

O processo de envelhecimento inicia-se à nascença e sabemos que a saúde não é uma questão aleatória, relaciona-se com escolhas, com o meio no qual se vive e com o acesso à saúde que se dispõe. O envelhecimento é diversificado, mas os profissionais tendem a generalizar os cuidados. Verificam-se políticas inadequadas, serviços desajustados, acessibilidade aos cuidados condicionada e consultas de Enfermagem desadequadas.

Abstract Pharmaceuticals are invaluable tools for the prevention and treatment of human and animal diseases. Human evolution led to the increase of life expectancy, which promoted the increase of consumption of pharmaceuticals. These compounds are consistently detected in superficial waters, and whilst degradation processes are expected to mitigate their levels, they also induce the formation of potentially harmful by-products. The compounds studied in this work were acetaminophen, 17α-ethynylestradiol ...
