Exploring bioactive compounds present in international patents targeting brain functions
The interest in nervous system disorders is an evident fact with more than 60 000
articles published on PUBMED only in the year of 2016. Actually, in our daily life
we are constantly exposed to different environmental factors known to be
prejudicial to the health of our nervous system. In this context, a holistic view of
food consumption is gaining increasing importance with the perspective of using
functional components of specific foods to improve our health or diminish the risk
of disease.
The aim of our work is to evaluate the use of nutritional food components of
traditional Portuguese diet in international patents of dietary supplements or the so
called functional foods described to improve brain functions.
The WIPO platform was used to collect data of these patents, and from the last 3
years we identified 35 patents using more than 150 different components. We
selected the most frequent components and the indications described in the patents,
and then examined the possible bioactive compounds for each component. The
prevalent functional components described were walnuts, peanuts, wolfberries,
mulberries, dates, jujube, creatine, carnitine, ginseng and soybean. Other
components rich in omega-3, such as docosahexaenoic acid and superba oil, were
also identified. These patents were described to target brain functions such as
intelligence, memory, concentration and in some cases compounds are indicated to
traumatic brain injury.
Regarding local sources, we found several nutritional components of traditional
Portuguese diet that have similar compounds of those found in the international
components described in patents. We believe this information will help in the
valorisation of national products.info:eu-repo/semantics/publishedVersio
From Assessing to Conserving biodiversity. Conceptual and Practical Challenges
This open access book features essays written by philosophers, biologists, ecologists and conservation scientists facing the current biodiversity crisis. Despite increasing communication, accelerating policy and management responses, and notwithstanding improving ecosystem assessment and endangered species knowledge, conserving biodiversity continues to be more a concern than an accomplished task. Why is it so? The overexploitation of natural resources by our species is a frequently recognised factor, while the short-term economic interests of governments and stakeholders typically clash with the burdens that implementing conservation actions imply. But this is not the whole story. This book develops a different perspective on the problem by exploring the conceptual challenges and practical defiance posed by conserving biodiversity, namely: on the one hand, the difficulties in defining what biodiversity is and characterizing that “thing” to which the word ‘biodiversity’ refers to; on the other hand, the reasons why assessing biodiversity and putting in place effective conservation actions is arduous. ; Features essays that are explicitly critical of the species approach to biodiversity Presents bio-philosophical perspectives on the interaction between biodiversity’s units, levels, and scales Serves as an interdisciplinary contribution to the emergent field of biodiversity studie
Use of CPAP to Reduce Arterial Stiffness in Moderate-to-Severe Obstructive Sleep Apnoea, Without Excessive Daytime Sleepiness (STIFFSLEEP): an Observational Cohort Study Protocol
INTRODUCTION: Sleepiness is a cardinal symptom in obstructive sleep apnoea (OSA) but most patients have unspecific symptoms. Arterial stiffness, evaluated by pulse wave velocity (PWV), is related to atherosclerosis and cardiovascular (CV) risk. Arterial stiffness was reported to be higher in patients with OSA, improving after treatment with continuous positive airway pressure (CPAP). This study aims to assess whether the same effect occurs in patients with OSA and without sleepiness.
METHODS AND ANALYSIS:
This observational study assesses the CV effect of CPAP therapy on a cohort of patients with moderate-to-severe OSA; the effect on the subcohorts of sleepy and non-sleepy patients will be compared. A systematic and consecutive sample of patients advised CPAP therapy will be recruited from a single outpatient sleep clinic (Centro Hospitalar de Lisboa Central-CHLC, Portugal). Eligible patients are male, younger than 65 years, with confirmed moderate-to-severe OSA and apnoea-hypopnea index (AHI) above 15/hour. Other sleep disorders, diabetes or any CV disease other than hypertension are exclusion criteria. Clinical evaluation at baseline includes Epworth Sleepiness Scale (ESS), and sleepiness is defined as ESS above 10. OSA will be confirmed by polygraphic study (cardiorespiratory, level 3). Participants are advised to undertake an assessment of carotid-femoral PWV (cf-PWV) and 24 hours evaluation of ambulatory blood pressure monitoring (ABPM), at baseline and after 4 months of CPAP therapy. Compliance and effectiveness of CPAP will be assessed. The main outcome is the variation of cf-PWV over time
Permanent-magnets linear actuators applicability in automobile active suspensions
Significant improvements in automobile suspension performance are achieved by active systems. However, current active suspension systems are too expensive and complex. Developments occurring in power electronics, permanent magnet materials, and microelectronic systems justifies analysis of the possibility of implementing electromagnetic actuators in order to improve the performance of automobile suspension systems without excessively increasing complexity and cost. In this paper, the layouts of hydraulic and electromagnetic active suspensions are compared. The actuator requirements are calculated, and some experimental results proving that electromagnetic suspension could become a reality in the future are shown
Energy efficiency in agriculture. Showcase and alternatives for wheat production in Portugal.
This chapter presents some results obtained in the KBBE.2011.4-04 project
“Energy Efficiency in Agriculture - AGREE” supported by the 7th Framework
Program. It gives an overview into energy use and energy efficiency in wheat
production in various agro-climatic zones of Europe. Among cereals, wheat is the
crop with the largest cultivated area in Europe. In 2008, the percentage share of
the area occupied by common and durum wheat in the countries analysed in the
AGREE project ranged from 2.4% in Portugal to 18.9% in Germany (Gołaszewski et
al., 2012). The different production systems in different climates vary substantially
in their energy use and energy saving potential. A showcase of conventional wheat
production in Portugal, where in 2012 it was cultivated in 54,761 ha (INE, 2013), is
presented and some production alternatives are analysed. The main objective was
to analyse the effect in the economic results, energy consumption and
environmental impacts of three wheat production systems alternatives: 1. no
tillage cropping systems, 2. reduction of phosphorous application and 3. the use
of supplemental irrigation

Redução de compostos fenólicos de resíduos de lagares de azeite utilizando culturas de Coriolus versicolor
In this study, C. versicolor cultures were performed during 20 days with different RLA (olive mill wastes)subtracts, 50%, 75% and 100%. During this assay, samples were collected in regular time intervals, cell growth were evaluated and broth decolorization was observed. The organic matter and total phenolic compounds level in
the culture broth showed a decrease in all RLA ratios. 50% and 75% RLA presented high total phenolic removal, 85% and 90% respectively. In the end of the assay, toxicological evaluation of the culture broth was performed against Artemia salina. These results showed a toxicological decrease of these residues after biological treatment
with C. Versicolor
Instagram: A gimmick or a serious reputation builder in the airline business?
The purpose of the research is to shed light on the interrelatedness between Instagram and corporate reputation on the one hand and customer service expectations on the other. A conceptual model is proposed to be tested in the context of the civil aviation economy. A national flagship airline company was chosen in which to conduct the research. An online questionnaire was made available and 283 responses were collected. Partial Least Squares Structural Equation Modelling (PLS-SEM) was used to test research hypotheses derived from the literature. The novelty of the work is in the scarce research found when scrutinizing the literature on possible links between Instagram and airline corporate reputation. The study found there to be a positive correlation between social media usage and corporate reputation in the airline sector. Future research needs to replicate this study across other airlines to ascertain the external validity of the current study and its potential for extrapolation.info:eu-repo/semantics/acceptedVersio
