Career Preparedness: The role of Experience before a PhD
Cadilhe, Maria; Almeida, Betariz; Rodrigues, Ana I.; Santos, MartaOECD-wide the number of PhD holders has been growing every year, but the job opportunities in the Higher Education Sector, as their privileged employer, do not seem to keep up with PhD holders’ numbers. This scenario paired with the current shifts in career trends may intensify the pressure on PhD students while considering the development of their future career paths. Past work experiences are a central aspect...
Career Preparedness: The role of Experience before a PhD
Cadilhe, Maria; Almeida, Betariz; Rodrigues, Ana I.; Santos, MartaOECD wide the number of PhD holders has been growing every year, but job opportunities in the Higher Education Sector, as their privileged employer, do not seem to keep up with PhD holders’ numbers [...]
A lab-made E-nose-MOS device for assessing the bacterial growth in a solid cult...
Dias, Teresa; Santos, Vítor S.; Zorgani, Tarek; Ferreiro, Nuno; Rodrigues, Ana I.; Zaghdoudi, Khalil; Veloso, Ana C. A.; Peres, António M.The detection and level assessment of microorganisms is a practical quality/contamination indicator of food and water samples. Conventional analytical procedures (e.g., culture methods, immunological techniques, and polymerase chain reactions), while accurate and widely used, are time-consuming, costly, and generate a large amount of waste. Electronic noses (E-noses), combined with chemometrics, provide a direc...
Impact of frost on the morphology and chemical composition of cv. Santulhana ol...
Rodrigues, Nuno; Casal, Susana; Rodrigues, Ana I.; Cruz, Rebeca; Peres, António M.; Pereira, J.A.Frost events and extreme weather phenomena greatly affect several characteristics of the olive fruit. This study evaluated the impact of frost on the morphology, composition (moisture, fat, fatty acids, tocopherols, and total phenolic contents), and antioxidant activity of olives of cv. Santulhana. A total of 14 trees from the same geographical region (Santulhão, northeast of Portugal) were chosen, including tr...
Luminescent halogen-substituted 2-(N-arylimino)pyrrolyl boron complexes: the in...
Rodrigues, Ana I.; Krishnamoorthy, Paramasivam; Gomes, Clara S. B.; Carmona, Nicolas; Di Paolo, Roberto E.; Pander, Piotr; Pina, JoãoA group of new boron complexes [BPh2{κ2N,N′-NC4H3-2-C(H)[double bond, length as m-dash]N-C6H4X}] (X = 4-Cl 4c, 4-Br 4d, 4-I 4e, 3-Br 4f, 2-Br 4g, 2-I 4h) containing different halogens as substituents in the N-aryl ring have been synthesized and characterized in terms of their molecular properties. Their photophysical characteristics have been thoroughly studied in order to understand whether these complexes exh...
Calcium phosphates and silicon: exploring methods of incorporation
Rodrigues, Ana I.; Reis, R. L.; Blitterswijk, Clemens A. van; Leonor, I. B.; Habibović, PamelaBackground: Bioinorganics have been explored as additives to ceramic bone graft substitutes with the aim to improve their performance in repair and regeneration of large bone defects. Silicon (Si), an essential trace element involved in the processes related to bone formation and remodeling, was shown not only to enhance osteoblasts proliferation but also to stimulate the differentiation of mesenchymal stem cel...
Combinatorial effect of silicon and calcium release from starch-based scaffolds...
Rodrigues, Ana I.; Oliveira, Mariana Braga; Mano, J. F.; Gomes, Manuela E.; Reis, R. L.; Leonor, I. B.Instructive materials able to drive cells, in particular the differentiation of stem cells toward osteoblastic lineages, have been investigated as a promising strategy for bone tissue engineering. Inorganic ions, such as phosphorus, calcium, silicon, and strontium, have been used in bone regeneration strategies as instructive ions for material-based approaches. The use of effective inorganic ions is being inves...
Antioxidant capacity, cytotoxicity and antimycobacterial activity of Madeira Ar...
Gouveia-Figueira, Sandra C.; Gouveia, Carla A.; Carvalho, Maria J.; Rodrigues, Ana I.; Nording, Malin L.; Castilho, Paula C.The potential bioactivity of dietary and medicinal endemic Helichrysum plants from Madeira Archipelago was explored, for the first time, in order to supply new information for the general consumer. In vitro antioxidant properties were investigated using DPPH, ABTS(•+), FRAP and β-Carotene assays, and the total phenolic content (TPC) and total flavonoid content (TFC) were also determined. Although the results ge...
A comprehensive assessment of the transcriptome of cork oak (Quercus suber) thr...
Pereira-Leal, José B.; Abreu, Isabel A.; Alabaça, Cláudia S.; Almeida, Maria H.; Almeida, Paulo; Almeida, Tânia; Amorim, Maria I.; Araújo, SusanaBackground: Cork oak (Quercus suber) is one of the rare trees with the ability to produce cork, a material widely used to make wine bottle stoppers, flooring and insulation materials, among many other uses. The molecular mechanisms of cork formation are still poorly understood, in great part due to the difficulty in studying a species with a long life-cycle and for which there is scarce molecular/genomic inform...
A Comparison of ( R , R )-Me-DUPHOS and ( R , R )-DUPHOS- i Pr Ligands in the P...
Marinho, Vanda Raquel; Ramalho, J. P. Prates; Rodrigues, Ana I.; Burke, Anthony J.A relatively unexploited commercial ligand, (R,R)-DUPHOSiPr(1b) was tested in the Pd0-catalysed asymmetric allylic alkyation reaction using rac-1,3-diphenylpropenyl acetate as substrate, malonate as nucleophile and a variety of Pd precatalysts under standard conditions. Excellent ee values (up to 98%) could be obtained with 1b, but the conversions were generally inferior to those obtained using (R,R)-Me- DUPHOS...
