Abstract This work aimed to evaluate the thermal and photo stability of the antioxidant potential (AP) of the Spirulina platensis biomass. Thermal stability was established at 25ºC, 40ºC and 50ºC for 60 days, in the dark, protected from light. Photo stability was evaluated using UV (15 W, λ = 265...
ABSTRACT We studied the effects of particulate and dissolved optically active components on the attenuation of photosynthetic active radiation (PAR) in a tropical lake. The temporal and spatial distribution of tripton, Chl-a and aCDOM(440) and their relative contribution to the diffuse PAR attenuation co...

Abstract Background and objectives: Laryngoscope is a key tool in anesthetic practice. Direct laryngoscopy is a crucial moment and inadequate laryngoscope's light can lead to catastrophic consequences. From our experience laryngoscope's light is assessed in a subjective manner and we believe a more prec...
RESUMO Objetivo: Avaliar a atividade antibacteriana contra Staphylococcus aureus e Pseudomonas aeruginosa de dois revestimentos endotraqueais com nanopartículas e fotocatálise sob luz visível. Métodos: Testaram-se dois tipos de nanopartículas de titânio: anatase padrão (TiO2) e TiO2 nano-dopada ...

Abstract The aim of this study was to compare vitroplants Catasetum x apolloi grown under natural light and artificial light and different concentrations of potassium silicate, providing data on the anatomical differentiation that aids the acclimatization process of this species. Plants from in vitro see...
ABSTRACT Objective To assess changes in blood-oxygen-level-dependent activity after light deprivation compared to regular light exposure in subjects with migraine in the interictal state and in controls. Methods Ten subjects with migraine and ten controls participated in two sessions of functional ma...

Abstract:Phyllonoma laticuspis leaves are used in Carrizal de Bravo, Guerrero, Mexico, to heal skin lesions such as injuries and smallpox sequelae and to treat diabetes mellitus type 2, and organic extracts of these leaves have been reported to exert antibacterial effects. High demand of P. laticuspis as...
Resumo O objetivo desse trabalho foi identificar a combinação do comprimento de onda e filtro que melhor detecta dente e osso e verificar qual material biológico (esmalte, raiz dental ou osso) possui maior fluorescência quando exposto a uma fonte de luz alternativa (ALS). Amostras de dente e osso for...
Objetivo: Avaliar os aparelhos fotopolimerizadores utilizados em clínicas da cidade do Recife e a manutenção realizada nesses aparelhos. Método: Os profissionais participaram da avaliação de forma voluntária e não foram identificados nos questionários que foram por eles respondidos. Foi pergunt...
Abstract:Ochradenus baccatus is a perennial glycophyte growing in Middle East and it is one of the most important food sources for many animal species in desert regions. The aim of our study was to investigate the effects of seed storage, light, temperature and gibberellic acid (GA3) on germination of O....
