Fruiting body, spores and in vitro produced mycelium of Ganoderma lucidum from ...
Heleno, Sandrina A.; Barros, Lillian; Martins, Anabela; Queiroz, Maria João R.P.; Santos-Buelga, Celestino; Ferreira, Isabel C.F.R.Ganoderma lucidum is one of the most extensively studied mushrooms due to its medicinal properties. Herein, a systematic study was carried out in order to compare the antioxidant activity of phenolic and polysaccharidic extracts from fruiting body, spores and mycelium, obtained in three different culture media, of G. lucidum from Northeast Portugal. Phenolic extracts were characterized using high-performance li...

Aplicaram-se 395 questionários, tendo-se assumido um erro amostral final d...
Molecular imprinting and surface grafting of glycoprotein fragments in polymeri...
Bzainia, Amir; Gomes, Catarina P.; Dias, Rolando; Costa, Mário RuiGlycoproteins and glycans are widely found in eukaryotes, prokaryotes, archaea, and viruses. Many fundamental biological mechanisms, such as molecular recognition, signal transduction, cell adhesion, and immune response are regulated with the intervention of glycoproteins, glycans, and monosaccharides. Several diseases are a result of anomalous changes affecting the structure of these molecules or their abnorma...
Biotechnological, nutritional and therapeutic uses of Pleurotus spp. (Oyster mu...
Corrêa, Rúbia C.G.; Brugnari, Tatiane; Bracht, Adelar; Peralta, Rosane M.; Ferreira, Isabel C.F.R.The particular characteristics of growth and development of mushrooms in nature result in the accumulation of a variety of secondary metabolites, several of them with biological activities. The genus Pleurotus is a cosmopolitan group of mushrooms with high nutritional value and therapeutic properties, besides a wide array of biotechnological and environmental applications. Scope and approach: The present report...
Cell-free layer measurements in a bifurcation microchannel : comparison between...
Bento, David; Pinho, Diana; Pinto, Elmano; Yaginuma, Tomoko; Correia, Teresa Montenegro; Lima, José; Pereira, Ana I.; Fernandes, Carla S.In the present work, in vitro blood flowing through a bifurcation microchannel was studied. The aim was to measure the Trajectories of the cell-free layer (CFL) by using different methods, i. e., a manual and two automatic methods.
Thermal analysis of hollow tubular sections under high temperatures
Fonseca, E.M.M.This work presents a numerical model for thermal analysis of steel hollow tubular sections under high temperatures. Curved and straight pipes are structural tubular elements of essential application in the fluids transport, chemical processes or energy generation plants, eventually subjected at mechanical and thermal loading conditions. Hollow tubular sections may have internal voids filled with air (hollow col...
Auditoria ambiental numa indústria automóvel: um caso de estudo
Cordeiro, João Filipe Alonso PinaCom o passar dos anos, a sociedade em geral e a indústria em particular, tomaram cada vez mais consciência dos impactos das atividades humanas no ambiente. Assim, as questões relacionadas com o ambiente têm ganho notório destaque. Desta forma, as organizações, estão sujeitas a cada vez mais medidas no sentido de diminuir os impactos que as suas atividades têm para com o meio ambiente. Houve, portanto, a necessi...
Adaptive genomic variation in honey bees from arid regions
Yadró Garcia, Carlos A.; Henriques, Dora; Haddad, N.; Obeidat, W. M.; AlShagour, B.; Muz, Mustafa Necati; Arab, A.; Eissa, A. A.; Hosri, C.The Middle East is home to a large number of Apis mellifera subspecies that have evolved under extreme aridity and desertic conditions. Therefore, they represent a unique opportunity to disentangle the genetic basis of adaptation to such challenging environmental conditions. We arranged a collection of 514 drone samples (haploid males) split into two latitudinal transects. Transect 1 comprised 342 samples: 66 A...
Governance windscanner.PT national research infrastructure (PINFRA/22207/2016)
Grosso, José; Campos, José; Ribeiro, Luís Frölén; Simões, TeresaThis document presents the governance structure foreseen for the operationalization of the WindScanner.PT research infrastructure. The methodology for the implementation of the governance structure, followed the one developed for the European Infrastructure WindScanner.EU, which was the origin of this Portuguese RI. However, as the European RI did not move forward due to a series of situations related to the in...
Composição química e propriedades bioativas de suplementos alimentares à base d...
Pereira, Carla; Barros, Lillian; Alves, Maria José; Calhelha, Ricardo C.; Santos-Buelga, Celestino; Ferreira, Isabel C.F.R.O cardo mariano é uma planta medicinal nativa da bacia do Mediterrâneo pertencente à família das Asteraceae. É amplamente reconhecido pelas suas propriedades terapêuticas muitas vezes associadas aos princípios ativos presentes nas suas sementes [1]. Neste trabalho, avaliou-se o valor nutricional do cardo mariano bem como a sua composição em ácidos orgânicos, açucares, tocoferóis e ácidos gordos. Estudou-se aind...
