University teachers’ conceptions of the university and the place of sustainability
Chaleta, E; Saraiva, M.; Sebastião, L.; Cid, M.; Dinis, A. M.; Leal, F.; Paulo Quaresma; Rato, L.In this phenomenographic qualitative research, the aim is to learn about the conceptions of university professors about the university. The study was carried out with 20 university professors: 10 from the School of Social Sciences and 10 from the School of Science and Technology of University of Évora with an average age of 54 years and over 20 years of professional activity. The data were collected through ope...
A PCR-based diagnostic assay for detecting DNA of the olive fruit fly, Bactroce...
Rejili, Mokhtar; Fernandes, Telma; Dinis, A. M.; Pereira, J. A.; Baptista, P.; Santos, S. A. P.; Lino-Neto, T.Bactrocera oleae (Rossi) (Diptera: Tephritidae) is considered the most devastating pest of the olive tree worldwide. In an effort to develop management and biological control strategies against this pest, new molecular tools are urgently needed. In this study, we present the design of B. oleae-specific primers based on mitochondrial DNA sequences of cytochrome oxidase subunit I (COI) gene. Two pairs of B. oleae...
Activity of Thymus capitellatus volatile extract, 1,8-cineole and borneol again...
Machado, M.; Dinis, A. M.; Santos-Rosa, M.; Alves, V.; Salgueiro, L.; Cavaleiro, C.; Sousa, M. C.In the search for new leishmanicidal agents, Thymus capitellatus Hoffmanns. & Link (family Lamiaceae) volatile extract and its major compounds, 1,8-cineole and borneol, were tested against Leishmania infantum, Leishmania tropica and Leishmania major. Plant volatile extract (essential oil) was analysed by GC and GC–MS and the activity of essential oil on Leishmania promastigotes viability was assessed using tetr...
Studies on the toxicity of an aqueous suspension of C60 nanoparticles using a b...
Santos, Sandra M. A.; Dinis, A. M.; Rodrigues, David M. F.; Peixoto, Francisco; Videira, Romeu A.; Jurado, A.S.The increasing use of C60 nanoparticles and the diversity of their applications in industry and medicine has led to their production in a large scale. C60 release into wastewaters and the possible accumulation in the environment has raised concerns about their ecotoxicological impact. In the present study, an aqueous suspension of C60 nanoparticles was prepared and its potential toxicity studied in laboratory, ...
A contribution to the ultrastructural knowledge of the pollen exine in subtribe...
Pereira Coutinho, A.; Dinis, A. M.Abstract To better understand the relationships within the Asteroideae and Inuleae, the structure of the pollen exine was investigated in seven genera and nine species of the subtribe Inulinae using LM, TEM and SEM. All taxa have a senecioid pattern of exine. The tectal complex consists of three main layers that differ in thickness and morphology: a tectum, a columellar layer, and a layer consisting of the basa...
Ultrastructural study of the relationship between generative and vegetative cel...
Dinis, A. M.; Mesquita, J. F.Summary InMagnolia ×soulangeana pollen grains the generative cell (GC) does not become totally free within the vegetative cell (VC), at least until the pollen tube emergence. Due to a deviation in its detachment process from the sporoderm, the opposing ends of the VC plasmalemma do not fuse themselves when the GC moves away from the intine. Consequently, the interplasmalemmic space surrounding the GC does not b...
