Abieta-7,13-Diene in Nematode-Infected Pinewood Pinus pinaster Branch Extracts:...
Gaspar, Marisa C.; Cruz, Pedro F.; Brito, Rui M. M.; Sousa, Hermínio C. de; Braga, Mara E. M.The oleoresin and volatile fraction produced by conifers, such as Pinus pinaster, play a crucial role in plant defence, acting as precursors to resin acids and adapting in response to environmental stress or pathogen attacks. Abietadiene (abieta-7,13-diene), the biosynthetic precursor to abietic acid, has been identified as the most abundant compound in extracts from pinewood nematode (PWN)-infected P. pinaster...
Preserving and hydrogel-matrixing the bioactive properties of aromatic medicina...
Parracho, Tiago; Cruz, Pedro F.; Peralta, Claúdia C.; Silva, Cândida G.; Campos, Maria Jorge; Neves, Marta; Cordeiro, Rachel; Trindade, DanielaEdible wild plants are part of the ethnobotanic heritage of a certain geographical area and are important sources of essential oils, antioxidants, minerals, and special flavours. Corema album (Portuguese crowberry), Crithmum maritimum (sea fennel), Eryngium maritimum (sea holly), Helichrysum italicum (curry plant) and Otanthus maritimus (cottonweed) wildly flourish along the sandy dunes of the coast of the Iber...
Retention of minerals, antioxidants, pigments, and glucosinolates by broccoli f...
Ribeiro, Vânia S.; Cruz, Pedro F.; Almeida, Zaida L.; Silva, Cândida G.; Silva, Maria Isabel; Silva, Inês S.; Santos, Liliana R.; Santos, Marta T.Given the poor palatability and chewability of crude green bean pods (Phaseolus vulgaris) and broccoli florets (Brassica oleracea var. italica Plenck) these vegetables are generally microwaved, steamed or water boiled. Hence, here, we evaluated the contents of minerals, antioxidants, phenolics, glucosinolates, pigments, colour, texture and flavour of water-boiling broccoli and green bean pods, with four mineral...
Nutritive Value and Bioactivities of a Halophyte Edible Plant: Crithmum maritim...
Correia, Iris; Antunes, Madalena; Tecelão, Carla; Neves, Marta; Pires, Cristiana L.; Cruz, Pedro F.; Peralta, Claúdia C.; Pereira, Cidália D.Crithmum maritimum L. (sea fennel), an edible xerophyte of coastal habitats, is considered an emerging cash crop for biosaline agriculture due to its salt-tolerance ability and potential applications in the agri-food sector. Here, the nutritional value and bioactive properties of sea fennel are described. Sea fennel leaves, flowers, and schizocarps are composed of carbohydrates (>65%) followed by ash, proteins,...
Customising sustainable bio-based polyelectrolytes: introduction of charged and...
Magalhães, Solange; Aliaño González, María José; Cruz, Pedro F.; Rosenberg, Rose; Haffke, Dirk; Norgren, Magnus; Alves, Luís; Medronho, BrunoAbstract: Cellulose has been widely explored as a sustainable alternative to synthetic polymers in industrial applications, thanks to its advantageous properties. The introduction of chemical modifications on cellulose structure, focusing on cationic and hydrophobic modifications, can enhance its functionality and expand the range of applications. In the present work, cationization was carried out through a two...
Stereoisomeric Tris-BINOL-Menthol Bulky Monophosphites: Synthesis, Characterisa...
Felgueiras, Alexandre P.; Rodrigues, Fábio M. S.; Carrilho, Rui M. B.; Cruz, Pedro F.; Rodrigues, Vítor H.; Kégl, Tamás; Kollár, LászlóFour stereoisomeric monoether derivatives, based on axially chiral (R)- or (S)-BINOL bearing a chiral (+)- or (-)-neomenthyloxy group were synthesised and fully characterised by NMR spectroscopy and X-ray crystallography. The respective tris-monophosphites were thereof prepared and fully characterised. The coordination ability of the new bulky phosphites with Rh(CO)2(acac), was attested by 31P NMR, which presen...
Edible flowers of Helichrysum italicum: Composition, nutritive value, and bioac...
Primitivo, Maria João; Neves, Marta; Pires, Cristiana L.; Cruz, Pedro F.; Brito, Catarina; Rodrigues, Ana C.; Carvalho, Carla C. C. R. deHelichrysum italicum (H. italicum) is a halophyte shrub with bright yellow flowers with a strong curry-like aroma. The essential oils of H. italicum have been used in the production of cosmetics and pharmaceuticals, due to their antiallergic and anti-inflammatory properties. In the agri-food sector, H. italicum flowers can be used for seasoning and flavoring food, and as natural food preservatives. Here, we rep...
Searching for the Best Transthyretin Aggregation Protocol to Study Amyloid Fibr...
Ferreira, Elisabete; Almeida, Zaida L.; Cruz, Pedro F.; Sousa, Marta Silva e; Veríssimo, Paula; Brito, Rui M. M.Several degenerative amyloid diseases, with no fully effective treatment, affect millions of people worldwide. These pathologies-amyloidoses-are known to be associated with the formation of ordered protein aggregates and highly stable and insoluble amyloid fibrils, which are deposited in multiple tissues and organs. The disruption of preformed amyloid aggregates and fibrils is one possible therapeutic strategy ...
DIBMA nanodiscs keep α-synuclein folded
Adão, Regina; Cruz, Pedro F.; Vaz, Daniela C.; Fonseca, Fátima; Pedersen, Jannik Nedergaard; Ferreira-da-Silva, Frederico; Brito, Rui M. M.α-Synuclein (αsyn) is a cytosolic intrinsically disordered protein (IDP) known to fold into an α-helical structure when binding to membrane lipids, decreasing protein aggregation. Model membrane enable elucidation of factors critically affecting protein folding/aggregation, mostly using either small unilamellar vesicles (SUVs) or nanodiscs surrounded by membrane scaffold proteins (MSPs). Yet SUVs are mechanical...
Corema album spp: Edible wild crowberries with a high content in minerals and o...
Brito, Catarina; Bertotti, Taciana; Primitivo, Maria João; Neves, Marta; Pires, Cristiana L.; Cruz, Pedro F.; Martins, Patrícia A. T.Edible wild plants are part of the ethnobotanical and gastronomic heritage of different geographical areas. Corema album (L.) D. Don is an endemic species of the dune systems of the Atlantic coast of the Iberian Peninsula. The aerial parts of Corema album are a source of nutrients and antioxidants. The Corema album white berry (Portuguese crowberry) is rich in calcium, iron, and zinc. The plant also shows high ...
