Pintarolas, a tangible sketch application
Dias, J. M. S.; Dehanov, J.; Cabral, C.; Carola, A.This paper presents Pintarolas, a simple sketch application that uses tangible interfaces as Human-Computer lnteraction modality. Totally sensor-less and cable-less interfaces (ordinary boardmarkers with fiducial markers attached), provide the means to support basic sketching tasks, such as drawing lines and sketching 2D primitive shapes (circle, triangle and square). The system requires an ordinary video camer...
Anticancer Properties of Essential Oils and Other Natural Products
Blowman, K.; Magalhães, M.; Lemos, M. F. L.; Cabral, C.; Pires, I. M.Essential oils are secondary metabolites with a key-role in plants protection, consisting primarily of terpenes with a volatile nature and a diverse array of chemical structures. Essential oils exhibit a wide range of bioactivities, especially antimicrobial activity, and have long been utilized for treating various human ailments and diseases. Cancer cell prevention and cytotoxicity are exhibited through a wide...

Ibuprofen nanocrystals developed by 22 factorial design experiment: A new appro...
Fernandes, A. R.; Ferreira, N. R.; Fangueiro, J. F.; Santos, A. C.; Veiga, F. J.; Cabral, C.; Silva, A. M.; Souto, E. B.The reduction of the particle size of drugs of pharmaceutical interest down to the nano-sized range has dramatically changed their physicochemical properties. The greatest disadvantage of nanocrystals is their inherent instability, due to the risk of crystal growth. Thus, the selection of an appropriate stabilizer is crucial to obtain long-term physicochemically stable nanocrystals. High pressure homogenization...
Bioconversion of cellulosic biomass wastes by Azorean hot spring bacterial cons...
Teixeira, M. B.; Cabral, C.; Toubarro, D.; Alves, M. M.; Pinho, D.; Egas, C.; Simões, N.Enzymatic hydrolysis of cellulose is a fundamental step in the carbon cycle and in the industrial bioconversion of biomass to biofuels. In nature cellulose hydrolysis is often catalysed by enzymes from complex microbial communities, nevertheless these studies are limited to a few isolates. Actually the production of biofuels from biomass became a necessity and novel pre-treatments are mandatory to be discovered...
Ridolfia segetum (L.) Moris (Apiaceae) from Portugal: A source of safe antioxid...
Cabral, C.; Poças Almeida, Juliana; Gonçalves, M.J.; Cavaleiro, C.; Cruz, M.T.; Salgueiro, L.Ridolfia segetum (L.) Moris essential oil was obtained by hydrodistillation and analysed by GC and GC-MS. The antioxidant properties were evaluated through the TBARS assay, and the in vitro anti-inflammatory activity was assessed through inhibition of NO production triggered by the Toll-like receptor 4 (TLR4) agonist, lipopolysaccharide (LPS), in mouse macrophages. Assessment of cell viability was made through ...

Abu-Darwish, M. S.; Cabral, C.; Ferreira, I. V.; Gonçalves, M. J.; Cavaleiro, C.; Cruz, M. T.; Al-bdour, T. H.; Salgueiro, L.Salvia officinalis L. (Lamiaceae) is a Mediterranean species, naturalized in many countries. In Jordan, it is used in traditional medicine as antiseptic, antiscabies, antisyphilitic, and anti-inflammatory, being frequently used against skin diseases. This study aimed the assessment of the antifungal and anti-inflammatory potential of its essential oils, and their cytotoxicity on macrophages and keratinocytes. T...
Analysis and Identification of Trihalomethanes in Lisbon Indoor Swimming Pools:...
Silva, Z.; Rebelo, H.; Silva, M.M.; Alves, A.; Cabral, C.; Almeida, A.C.; Aguiar, F.; Oliveira, A.; Nogueira, A.; Pinhal, H.; Matos, A.; Ramos, C.D.Water disinfection methods are used in swimming pools to ensure an effective protection of users against microbiological pathogens, being chlorination the most common disinfection method used worldwide. The use of chlorine based treatment techniques has one strong drawback, which is the generation of disinfection by-products (DBPs), potentially harmful products that have been associated with respiratory and ocu...
