Avaliação farmacológica e toxicológica do óleo essencial e extrato aquoso deLav...
Arantes, Silvia; Candeias, M. Fátima; Pereira, Marízia; Lopes, Orlando; Lima, Mónica; Cruz Morais, Júlio; Martins, M. RosárioAs plantas do género Lavandula L. pertencentes à família Labiatae, são plantas aromáticas de grande importância económica muito usadas na medicina tradicional. Neste estudo, foi selecionada uma espécie natural do Alentejo, Lavandula stoechas L. subsps. luisieri (Rozeira) Rozeira, vulgarmente conhecida por rosmaninho, recolhida de uma mancha da Herdade da Mitra (Évora) O objetivo deste estudo foi avaliar as ati...
Toxicological and pharmacological evaluation of the essential oil and aqueous e...
Arantes, Silvia; Candeias, M. Fátima; Pereira, Marizia; Lopes, Orlando; Lima, Mónica; Martins, M. RosárioLavenders belong to the family Labiatae and represent some of the most popular medicinal plants extensively used in aromatherapy. In this study, we selected Lavandula stoechas L. subsp. luisieri (Rozeira) Rozeira, endemic of Portugal, collected in Évora (Alentejo). The aim of this study was to evaluate the acute toxicity and the analgesic and anti-inflammatory activities of the essential oil and aqueous extrac...
Variations in salivary function in a rodent model of pre-diabetes
Rodrigues, Lénia; Mouta, Raquel; Barra, Cátia; Costa, Ana R; Silva, Fernando C; Lopes, Orlando; Lima, Mónica; Lamy, ElsaDiabetes is a widespread disease representing an enormous part of the total health costs. An early diagnostic could be of extremely importance both for the understanding and prevention of this pathology. Saliva is a fluid with increasing interest as a source of biomarkers for disease diagnostic and saliva protein composition changes have already been reported for diabetic individuals. However, the studies were ...
"Circuloterapia": uma metáfora para o enfrentamento da dor crônica em duas clín...
Lima,Mônica Angelim Gomes de; Trad,Leny Alves BomfimEste artigo descreve e analisa a dinâmica da clínica de dor enquanto um "artefato complexo" do sistema terapêutico biomédico, explorando as múltiplas vozes e as relações dialógicas sobre dor e a interdisciplinaridade no cotidiano clínico de duas clínicas de dor situadas em hospitais-escola nas cidades de Salvador e São Paulo. Foi realizado estudo etnográfico orientado pela antropologia interpretativa, na qual s...
Métodos utilizados na avaliação psicofísica da visão de cores humana
Lima,Monica Gomes; Gomes,Bruno Duarte; Ventura,Dora Fix; Silveira,Luiz Carlos de LimaA cor é um atributo perceptual que nos permite identificar e localizar padrões ambientais de mesmo brilho e constitui uma dimensão adicional na identificação de objetos, além da detecção de inúmeros outros atributos dos objetos em sua relação com a cena visual, como luminância, contraste, forma, movimento, textura, profundidade. Decorre daí a sua importância fundamental nas atividades desempenhadas pelos animai...
Adventitious rooting of conifers: influence of physical and chemical factors
Ragonezi, Carla; Klimaszewska, Krystyna; Castro, Mário Rui; Lima, Mónica; Oliveira, Paulo; Zavattieri, Maria AmelyIn conifers, vegetative propagation of superior genotypes is the most direct means for making large genetic gains, because it allows a large proportion of genetic diversity to be captured in a single cycle of selection. There are two aims of vegetative propagation, namely large-scale multiplication of select genotypes and production of large numbers of plants from scarce and costly seed that originates from con...
Influence of light quality and intensity on adventitious root formation in micr...
Ragonezi, Carla; Castro, Mário Rui Basílio; Klimaszewska, Krystyna; Lima, Mónica; Zavattieri, Maria AmelyIn the present study of Pinus pinea L., further improvement of microshoot rooting was achieved by applying Cool-white light at increased intensity from 60 to 90 µmol m-2 s-1. In contrast, light provided by Gro-lux lamps promoted rooting of the microshoots at the same frequency regardless of its intensity. Majority of microshoots (70.4%) grown under Cool-white lamps at the intensity of 90 µmol m-2 s-1 were also ...
Mycorrhiza-like structures in rooted microshoots of Pinus pinea L.
Castro, Mário Rui da Costa Basílio e; Ragonezi Gomes Lopes, Carla Aparecida; Klimaszewska, Krystyna; Lima, Mónica; Oliveira, Paulo Guilherme dePinus pinea L. (stone pine) is one of the major plantation species in Iberian Peninsula, being Portugal the largest edible seed producer in the world. The induction and improvement of in vitro rhizogenesis of microshoots of Pinus pinea was developed in our laboratory using a co-culture system with ECM fungi. In the acclimation phase in mixed substrates, or in rhizotrons, anatomical and morphological studies wer...

Induction of somatic embryogenesis as an example of stress-related plant reactions
Zavattieri, Maria Amely; Frederico, António Miguel; Lima, Mónica; Sabino, Rui; Arnholdt-Schmitt, BirgitIn this review, we address the role of stress as one of the principal causes for a cell or tissue to change its preexisting somatic program, reprogramming itself to express the embryogenic pathway. The focus of this paper is the effect of different stress conditions on the induction phase of plant somatic embryogenesis, as well as the development of embryogenic competence as a result of the applied stresses. We...
