Modelling Molecular and Inorganic Data of Amanita ponderosa Mushrooms using Art...
Salvador, Cátia; Martins, M. Rosário; Vicente, Henrique; Neves, José; Arteiro, José; Caldeira, A. TeresaAbstract Wild edible mushrooms Amanita ponderosa Malenc¸on and Heim are very appreciated in gastronomy, with high export potential. This species grows in some microclimates, namely in the southwest of the Iberian Peninsula. The results obtained demonstrate that A. ponderosa mushrooms showed different inorganic composition according to their habitat and the molecular data, obtained by M13-PCR, allowed to disting...
Molecular approach to characterize ectomycorrhizae fungi from Mediterranean pin...
Ragonezi, Carla; Caldeira, A. Teresa; Martins, M. Rosário; Salvador, Cátia; Santos-Silva, Celeste; Ganhão, Elsa; Klimaszewska, KrystynaStone pine (Pinus pinea L.), like other conifers, forms ectomycorrhizas (ECM), which have beneficial impact on plant growth in natural environments and forest ecosystems. An in vitro co-culture of stone pine microshoots with pure mycelia of isolated ECM sporocarps was used to overcome the root growth cessation not only in vitro but also to improve root development during acclimation phase. Pisolithus arhizus (S...
Síntese de ácidos e ésteres mono- e bisfosfónicos derivados do indazole
Teixeira, António P. S.; Afonso, Silvânia S.; Martins, M. Rosário; Teixeira, Fátima C.Os bisfosfonatos (BPs) constituem um grupo de compostos derivados do ácido bisfosfónico e dos seus sais, onde o grupo P-O-P foi substituído por um bioisoster, resultando na estrutura P-C-P, que lhe confere maior estabilidade química e metabólica. Os bisfosfonatos (BPs) constituem uma classe importante de fármacos, com aplicações terapêuticas no tratamento de doenças do metabolismo mineral do osso, como a osteop...
New Phosphonic Acids and Esters Derived from Indazole: Synthesis and Biological...
Teixeira, António P. S.; Afonso, Silvânia S.; Martins, M. Rosário; Teixeira, Fátima C.Bisphosphonates (BPs) are a group of compounds derived from bisphosphonic acid and their salts, with a P-C-P structure which confers higher metabolic and chemical stability. They are an important class of drugs with therapeutic applications in the treatment of diseases of bone mineral metabolism such as osteoporosis and Paget's disease. These compounds have also shown activity in other areas, such as antitumor ...
ENZYMATIC MONITORIZATION OF MURAL PAINTINGS BIODETERIORATION
Rosado, Tânia; Martins, M. Rosário; Pires, Margarida; Mirão, José; Candeias, A; Caldeira, A TeresaBiodeterioration of mural paintings by microorganisms is an important research field that needs novel approaches to fully understand the mechanisms and effects. In this work, the presence of microorganisms and their biological activity were investigated by extra and intracellular enzymatic monitorization. The enzymes arylsulphatase, β-glucosidase, dehydrogenase and phosphatase were used as biomarkers of the mic...
Combined characterisation and biodegradation assessment methodology of mural pa...
Rosado, T; Gil, M; Caldeira, A Teresa; Martins, M Rosario; Dias, C; Carvalho, L; Mirão, J; Candeias, A EThe aim of this work was the material characterisation of wall paintings and biodegradation assessment, including the analysis of microbial growth and the effect of microbial proliferation, in view of their conservation. The methodology was applied to the study of frescoes dated from 1531, located in the ancient parish church of Santo Aleixo, Southern Portugal. The combined use of optical microscopy, SEM-EDS an...
Molecular evaluation of some Amanita ponderosa and fungal strains living in ass...
Salvador, C; Martins, M Rosário; Arteiro, J M; Caldeira, A TeresaAmanita ponderosa are wild edible mushrooms that grow only in some microclimates, particularly those in the southwestern part of the Iberian Peninsula. Due to the vast diversity of mushrooms in nature, as well as nutrient variability, which is highly dependent on soil type and environmental conditions, it is essential to be able to characterize fungal microbiota that lives in association with mushrooms and to d...
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...
Degradation of Metalaxyl and Folpet by Filamentous Fungi Isolated From Portugue...
Martins, M. Rosário; Pereira, Pablo; Lima, Nelson; Cruz-Morais, JúlioDegradation of xenobiotics by microbial populations is a potential method to enhance the effectiveness of ex situ or in situ bioremediation. The propose of this study was to evaluate the impact of repeated metalaxyl and folpet treatments on soil microbial communities and to select soil fungal strains able to degrade these fungicides. Results showed an enhanced degradation of metalaxyl and folpet in vineyards so...
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...
