Chemical composition and pharmacological activities of essential oils of Lavandula spp.

Lavandula spp. belong to the family Lamiatae and some species are often used in popular medicine and have been used for centuries in a large number of medical applications and in aromatherapy. Although similar ethnobotanical properties of Lavandula spp., its essential oils, general chemical composition and therapeutic applications differ from different species. Lavandula stoechas L. subsps. luisieri (Rozeira) Rozeira and L. viridis L’Hér are endemic to the Iberian Peninsula, widespread in the South of Portugal, namely in Southern Alentejo and Algarve. The aim of our study was evaluate the chemical composition and toxicological and pharmacological activities of leaves essential oils of spontaneous plants of L. stoechas L. subsps. luisieri (Alentejo) and L. viridis (Algarve). The essential oils of these wild plants, collected in spring, were obtained by hydrodistillation in a Clevenger-type apparatus and its chemical composition was evaluated by GC/FID. The acute toxicity of essential oils was evaluated "in vitro" using brine shrimp (LC50) and "in vivo" using Swiss mice (DL50). The analgesic and anti-inflammatory pharmacological properties of L. stoechas subsp. luisieri essential oil were evaluated in mouse or rats by the Amour-Smith and carrageen-induced paw edema tests, respectively. Results showed important differences in chemical composition of essential oils from two species analyzed either to diversity and proportion of its constituents. The essentials oils showed citotoxicity against Artemia salina and a DL50 higher than 2000 mg/kg for mice. The analgesic and anti-inflammatory activities of essential oils were exhibit for the doses of 100 and 200 mg/kg.

CHEMICAL COMPOSITION AND ANTIMICROBIAL ACTIVITY OF ESSENTIAL OILS OF LAVANDULA SPP.

Lavenders belong to the family Labiatae and represent some of the most popular medicinal plants of great economic importance. Their essential oils are important for the perfume, cosmetic, flavouring and pharmaceutical industries. However, despite its popularity, and the long tradition of use, biological properties of the various Lavandula species are not yet been well sustained by scientific or clinical studies and some available data being inconclusive and controversial [1]. Although Lavandula spp. have similar ethnobotanical properties, however, chemical composition and therapeutic uses differ from different species and main composition of essential oils showed differences with species and with the region were they grow [1,2,3]. L. stoechas L. subsps. luisieri (Rozeira) Rozeira. L. pedunculata (Mill.) Cav. and L. viridis L’Hér are endemic to the Iberian Peninsula, widespread in the South of Portugal, namely in Alentejo and Algarve. In our work, essential oils from the stems or leaves from wild grown plants of L. luisieri (Alentejo), L. pedunculata (Alentejo) and L. viridis (Algarve), were extracted by hydrodistillation and analyzed by GC-FID. Antimicrobial activity was evaluated by solid diffusion disk assay and minimal inhibitory concentration (MIC) against pathogenic Gram-positive and Gram-negative bacteria and food spoilage fungi.

Comportamentos agressivos entre pares e padrões de vinculação: um estudo com jovens adolescentes

O presente estudo, desenvolvido com 237 jovens de três escolas do distrito de Évora, teve como objetivos caracterizar e analisar os comportamentos relacionados com situações de bullying (vitimação, do agressão e observação); e analisar a existência de eventuais relações entre padrões de vinculação e comportamentos agressivos entre pares. Utilizaram-se dois questionários de auto-relato, nomeadamente o QEVE – Questionário de Exclusão Social e Violência Escolar (Martins, 2003), que mede os comportamentos de agressão, vitimação e observação; e o IVIA – Inventário sobre Vinculação para a Infância e a Adolescência (Carvalho, Soares & Baptista, 2006), que analisa um conjunto de comportamentos e representações da vinculação na infância e na adolescência. Ambos os instrumentos mostraram boas qualidades psicométricas. Os resultados mostraram uma clara prevalência de situações de observação, relativamente às situações de agressão e de vitimação. Em todas estas situações, os comportamentos relacionados com a Exclusão Social e Agressão Verbal são os mais frequentes, comparativamente aos comportamentos relacionados com a Agressão Física. Os rapazes apresentaram médias mais elevadas em todas as escalas; os estudantes com menor percepção de suporte social na escola eram os que evidenciavam mais comportamentos de vitimação. No que se refere aos padrões de vinculação, os resultados mostraram que a vinculação segura parece funcionar como um fator protetor para a vitimação e para a agressividade. A partir dos resultados obtidos, serão analisadas pistas para uma intervenção psicoeducativa.

Antioxidant,antimicrobial and toxicological properties of Schinus molle L. essential oils

Ethnopharmacological relevance: Schinus molle L. has been used in folk medicine as antibacterial, antiviral, topical antiseptic, antifungal, antioxidant, anti-inflammatory, anti-tumoural as well as antispasmodic and analgesic; however, there are few studies of pharmacological and toxicological properties of S. molle essential oils. Aim of the study: The aim of this study was to evaluate the antioxidant and antimicrobial activities of S. molle leaf and fruit essential oils, correlated with their chemical composition and evaluate their acute toxicity. Materials and methods: The chemical composition of S. molle leaf and fruit essential oils were evaluated by GC-FID and GC-MS. Antioxidant properties were determined using the 2,2-diphenyl-1-picryl-hydrazyl (DPPH) free radical and β-carotene/linoleic acid methods. Antimicrobial properties were evaluated by the agar disc diffusion method and minimal inhibitory concentration assay. Toxicity in Artemia salina and acute toxicity with behavioural screening in mice were evaluated. Results: The dominant compounds found in leaf and fruit essential oils (EOs) were monoterpene hydrocarbons, namely -phellandrene, β-phellandrene, β-myrcene, limonene and α-pinene. EOs showed low scavenging antioxidant activity by the DPPH free radical method and a higher activity by the β-carotene/linoleic acid method. Antimicrobial activity of EOs was observed for Gram+, Gram– pathogenic bacteria and food spoilage fungi. EOs showed cytotoxicity for Artemia salina and lower toxicity in Swiss mice. Conclusions: The result showed that EOs of leaves and fruits of S. molle demonstrated antioxidant and antimicrobial properties, suggesting their potential use in food or pharmaceutical industries.

ANTIOXIDANT, ANTIMICROBIAL AND TOXICOLOGICAL PROPERTIES OF SCHINUS MOLLE L. ESSENTIAL OILS

Schinus molle L. is commonly known as pink pepper or American pepper, of Anacardiaceae family, from subtropical regions of South America, introduced and naturalized in South Europe, including Portugal. In folk medicine, plant extracts and essential oil has related as having antibacterial, antiviral, antifungal, anti-inflammatory, antitumoral, antispasmodic, analgesic and antidepressive properties. The aim of present study was to evaluate the chemical composition and biological activities of essential oil extracted from leaves and fruits of S. molle. For this purpose, the essential oils were analyzed by gas chromatography (GC/FID) and antioxidant properties were evaluated by the free radical DPPH and by system β-carotene/linoleic acid methods. The antimicrobial activities were screened against pathogenic bacteria and fungi and food spoiling fungi by the disc diffusion assay and minimal inhibitory concentration (MIC) was determined for sensitive strains. Toxicity of essential oils were carried out by the brine shrimp mortality test (EC50) and acute lethal dose (DL50) determination after oral administration in Swiss mice The major components in leaf essential oil were α-phellandrene, β-phellandrene and limonene, while myrcene, α-phellandrene and 1,8-cineole are the main components in the fruit essential oil. The essential oils of leaf and fruit of S. molle showed antioxidant activity through the two mechanisms: the ability to capture free radicals and protection of lipid peroxidation. These oils exhibited also a broad microbial activity spectrum, against pathogenic bacteria Gram-positive and Gram-negative and Candida spp. The fruit essential oil showed high cytotoxicity against Artemia salina. Essential oils of leaves and fruits of S. molle showed significant antioxidant and microbial properties, so the studies continue to clarify more in deep its toxicity, including hepatotoxicity and nephrotoxicity, and to evaluate its medicinal or nutraceutical potential.

Portugal e Brasil – dois países, quantas línguas? Critérios para a Definição de Entidades Linguísticas no Espaço Lusófono

A identificação de critérios para a definição de entidades linguísticas é complexa. No espaço lusófono, tal definição tem associadas consequências em termos linguísticos e sócio-políticos que se procuram caracterizar no presente trabalho, em que se recorre a dados da Aquisição das normas europeia e brasileira do Português para responder a uma questão complexa: quantas línguas existem no espaço da lusofonia? A principal conclusão é a de estamos (ainda) perante uma única entidade linguística a que chamamos "língua", apesar das diferenças que aqui são apontadas e caracterizadas.

Engenharia Geológica na Universidade de Évora. A experiência dos estágios integrados em empresas no 1º Ciclo – Modelo 3G; Prosseguimento de estudos e integração de alunos no exterior no âmbito do 2º Ciclo.

Resumo Resultado de um investimento em meios humanos e materiais no domínio da Geo-Engenharia, ao longo de quase três décadas, a Universidade de Évora detém hoje um reconhecimento junto dos empregadores que têm acolhido os alunos desta instituição nas suas empresas. Este trabalho destina-se a partilhar a experiência que a Universidade de Évora (UE) acumulou no Ensino e Formação em Geo-Engenharia, em contexto empresarial. O Curso de Licenciatura em Engenharia Geológica da Universidade de Évora (LEG), assim como mais dois cursos da UE são pioneiros em Portugal, na medida em que preveem nos seus planos curriculares a possibilidade de os alunos puderem realizar estágios em contexto de trabalho no âmbito de Unidades Curriculares do 6º Semestre dos respetivos Cursos. No caso do LEG, apôs um período intensivo de quatro a cinco semanas de formação na Universidade, seguem-se três semanas de estágio numa empresa a eleger entre as trinta e duas que até agora aceitaram estabelecer protocolos para este fim. Este processo repete-se duas vezes por semestre. Em alternativa, os alunos que não desejem frequentar estes estágios terão uma formação clássica na Universidade. Neste artigo, apresentam-se os resultados até agora alcançados com este ensino diferenciado. A adaptação ao modelo de Bologna dos ensinos de 1º e 2º Ciclo resultou num défice de formação curricular indispensável para o pleno exercício da profissão de Engenheiro Geólogo. As competências específicas adquiridas ao fim de cada ciclo foram indicadas pela Ordem dos Engenheiros que contudo ressalva a necessidade de uma formação em Engenharia no 1º Ciclo para reconhecer as competências a atribuir a cada graduado nos mestrados de Engenharia. A experiência de formação no 2º ciclo em Engenharia Geológica, onde sensivelmente metade dos alunos é externa a Universidade de Évora, é alvo de análise neste trabalho. Palavras-Chave: Ensino; Engenharia Geológica; Bolonha; Competências; Empregabilidade Abstract Result of an investment in human and material resources in the field of Geo-Engineering, over nearly three decades, the University of Évora has now a recognition among employers that have accepted students of this institution in their companies. This work intended's to share University of Évora (UE) business context accumulated experiences in Education and Training in Geo-Engineering. The Degree in Geological Engineering from the University of Évora (LEG), as well as two courses in the UE are pioneers in Portugal, to the extent their curricula to possible students internships that can be perform in the workplace under Curricular Units of the 3th Year of the courses. In the case of the LEG, after an intensive period of four to five weeks of training at the University the students who desire it, can have a three weeks internship in a company to elect between the thirty-two that so far agreed to establish protocols with the UE, for this purpose. This process is repeated twice per semester. Alternatively, students who do not wish to attend these stages will have a classical education at the University. In this article, we present the results achieved so far with differentiated teaching. The adaptation to the Bologna model of 1st and 2nd cycles resulted in a lack of training curriculum essential to the full exercise of the Engineer Geologist profession. The specific skills acquired at the end of each cycle were indicated by the Engineers Chamber, however pointed needed training in the 1st Cycle Engineering to recognize the skills to give each graduate in Masters of Engineering. The experience of training in the 2nd cycle in Geological Engineering, where roughly half of the students came outside of the University of Évora, is also analyzed in this work.

Portugal, país em que se destaca a Região do Alentejo como a mais envelhecida, vive-se este complexo fenómeno, pelo que se coloca com toda a acuidade o desenvolvimento de estudos com o objetivo de conhecer melhor os contornos desta realidade e que permitam empreender medidas que ajudem a melhor lidar com ela. Assim sendo, desenvolveu-se o presente estudo cujos objetivos são caraterizar o fenómeno da violência sobre os idosos, no Alentejo e analisar as representações sociais de violência sobre os idosos, no Alentejo.

Medication regimen complexity in institutionalized elderly people in an aging society

Background Complex medication regimens may adversely affect compliance and treatment outcomes. Complexity can be assessed with the medication regimen complexity index (MRCI), which has proved to be a valid, reliable tool, with potential uses in both practice and research. Objective To use the MRCI to assess medication regimen complexity in institutionalized elderly people. Setting Five nursing homes in mainland Portugal. Methods A descriptive, cross-sectional study of institutionalized elderly people (n = 415) was performed from March to June 2009, including all inpatients aged 65 and over taking at least one medication per day. Main outcome measure Medication regimen complexity index. Results The mean age of the sample was 83.9 years (±6.6 years), and 60.2 % were women. The elderly patients were taking a large number of drugs, with 76.6 % taking more than five medications per day. The average medication regimen complexity was 18.2 (±SD = 9.6), and was higher in the females (p < 0.001). The most decisive factors contributing to the complexity were the number of drugs and dosage frequency. In regimens with the same number of medications, schedule was the most relevant factor in the final score (r = 0.922), followed by pharmaceutical forms (r = 0.768) and additional instructions (r = 0.742). Conclusion Medication regimen complexity proved to be high. There is certainly potential for the pharmacist’s intervention to reduce it as part as the medication review routine in all the patients.

Estudo preliminar sobre a ação antimicrobiana de óleos essenciais sobre agentes etiológicos de mastite em ovelhas

The control of mastitis is currently reliant on antibiotic utilization. Nevertheless antibiotics overuse and use without criteria leads to the development of resistant strains with negative consequences both in animal and public health. Essential oils (EOs) are classified as GRAS (generally recognized as safe), are provided with antimicrobial properties and no resistance has been reported after use. The aim of this study was to evaluate the antimicrobial activity of EOs of aromatic herbs, growing wild in Alentejo region and widely used in Mediterranean food, against microorganisms isolated from ovine mastitic milk.
