The Prevalence of Aberrant Nasal Turbinates and Nasal Septum Deviation in a Fre...
Carlos, A.; Pereira, H.; Pereira, A.; Oliveira, M.; Ferreira, D.The presence of nasal septum deviation and aberrant turbinates alters the normal nasal airflow. The relevance of nasal septum deviation in the brachycephalic obstructive airway syndrome (BOAS) is still unclear but, together with other anatomical alterations such as aberrant turbinates, may alter the normal nasal airflow, increasing upper airway resistance. The present retrospective study reports the prevalence ...
Examining banks' response to climate risks: Insights from Portugal
Rebelo, J.; Pereira, H.; Pinheiro, C.Banks play a pivotal role in the economy and are exposed to various financial risks, including those stemming from climate change. In addition to physical, direct, or indirect risks, transition risks have attracted special attention from boards of directors, particularly banks facing stringent regulatory deadlines (such as the green asset ratio and the banking book taxonomy alignment ratio), along with other ob...
Optimization of key growth parameters involved in biomass production of Pavlova...
Maciel, Filipe; Couto, D.; Geada, Pedro; Pereira, H.; Teixeira, J. A.; Domingues, M.; Silva, J.; Vicente, A. A.Microalgae have been presented as an interesting source of bioactive compounds for human consumption in several industries, such as nutraceutical, pharmaceutical or cosmeceutical. Their rich composition in anti-inflammatory and antioxidant compounds (e.g., polyunsaturated fatty acids (PUFAs), proteins) have shown protective effects against several human diseases (e.g., cardiovascular, cancer). Despite their inc...
Stent for life initiative in Portugal: Progress through years covid-19 impact
Pereira, E.; Calé, R.; Pereira, Â. M.; Pereira, H.; Martins, L.Background: During Stent for Life Initiative in Portugal lifetime, positive changes in ST elevation myocardial infarction treatment were observed, by the increase of Primary Angioplasty numbers and improvements in patients’ behaviour towards myocardial infarction, with an increase in those who called 112 and the lower proportion attending non primary percutaneous coronary intervention centres. Despite public aw...
Towards engineered yeast as production platform for capsaicinoids
Muratovska, N.; Silva, P.; Pozdniakova, T. A.; Pereira, H.; Grey, C.; Johansson, Björn; Carlquist, M.Capsaicinoids are bioactive alkaloids produced by the chili pepper fruit and are known to be the most potent agonists of the human pain receptor TRPV1 (Transient Receptor Potential Cation Channel Subfamily V Member 1). They are currently produced by extraction from chili pepper fruit or by chemical synthesis. Transfer of the biosynthetic route to a microbial host could enable more efficient capsaicinoid product...
The Influence of Solvent and Extraction Time on Yield and Chemical Selectivity ...
Simões, Rita; Miranda, Isabel; Pereira, H.The cuticular lipid compounds, usually named cuticular waxes, present in the cuticular layering of Quercus suber adult leaves were extracted with solvents of different polarities (n-hexane, dichloromethane and acetone) and analysed by GC–MS. Q. suber leaves have a substantial cuticular wax layer (2.8% of leaf mass and 239 g/cm2), composed predominantly by terpenes (43–63% of all compounds), followed by aliphati...
The physicomechanical and thermal properties of Algerian Aleppo pine (Pinus hal...
Lakreb, N.; Sen, U.; Bezzazi, B.; Pereira, H.Aleppo pine (Pinus halepensis Mill.) is the main forest species of Algeria occupying more than 35% of the total forest area of the country. However, the physicomechanical and thermal characteristics of Algerian P. halepensis wood are not well-known. This research investigates the physical (moisture, density, swelling, and shrinkage), mechanical (bending strength and modulus of elasticity), and thermal (mass los...
Integrated Bioprocess for Structured Lipids, Emulsifiers and Biodiesel Producti...
Heinzl, G.C.; Mota, D.A.; Martinis, V.; Martins, A.S.; Soares, C.M.F.; Osório, N.; Gominho, J.; Nampoothiri, K.M.; Sukumaran, R.K.; Pereira, H.Olive pomace oil (OPO), a by-product of olive oil industry, is directly consumed after refining. The novelty of this study consists of the direct use of crude high acidic OPO (3.4–20% acidity) to produce added-value compounds, using sn-1,3-regioselective lipases: (i) low-calorie dietetic structured lipids (SL) containing caprylic (C8:0) or capric (C10:0) acids by acidolysis or interesterification with their eth...
Effects of LED lighting on Nannochloropsis oceanica grown in outdoor raceway ponds
Carneiro, M.; Maia, Inês Beatriz; Cunha, P.; Guerra, I.; Magina, T.; Santos, Tamara; Schulze, Peter S.C.; Pereira, H.; Malcata, F. X.; Navalho, J.Growth in most microalgal mass cultivation systems is light-limited, particularly in raceway ponds (RWP) where the light path is higher. Artificial lighting can be a promising solution to diminishing dark zones and enhance microalgal productivity. Therefore, our goal was to prevent the cell shift from photosynthesis to a respiration-only stage by resorting to LED illumination. Nannochloropsis oceanica cultures ...
Evaluation of FT - Raman and FTIR – ATR spectroscopy for the quality evaluation...
Anjos, O.; Guiné, Raquel; Santos, A. J. A.; Paula, V. B.; Pereira, H.; Estevinho, L. M.Mono fl oral Lavandula spp. honey is very appre - ciated by consumers due to its characteristic and pleasant aroma and fl avor. Given the economic importance of this type of honey, it is important to develop a rapid and non - expensive methodology that allows certifying its quality. In this context, this study aimed to compare the applic - ability and accuracy of FTIR - ATR and FT - Raman techni - ques for the qu...
