Essential oils composition of <i>Salvia lachnostachys</i> and <i>S. melissiflora</i> (Lamiaceae)

Os óleos essenciais de Salvia lachnostachys (folhas e flores) e S. melissiflora (folhas), obtidos por hidrodestilação, foram analisados por CG e CG/EM. Os óleos foram caracterizados por um elevado teor de compostos alifáticos. Nos óleos de S. lachnostachys o componente majoritário foi o ácido dodecanóico (folhas 61,6%, flores 73,4%). No óleo das folhas de S. melissiflora os componentes principais foram ácido linoleico (29,3%), ácido hexadecanóico (11,3%) e óxido de cariofileno (9,6%). Este é o primeiro relato de estudo de óleos essenciais nestas duas espécies.The essential oils isolated by hydrodistillation of Salvia lachnostachys Benth. (leaves and flowers) and S. melissiflora Benth. (leaves) were analyzed by capillary GC/MS. The oils were characterized by high content of aliphatic compounds. In the essential oils of S. lachnostachys the major component was dodecanoic acid (61.6% in leaves and 73.4% in flowers). In the essential oil of S. melissiflora the main components were linoleic and hexadecanoic acids (29.3% and 11.3%, respectively) and caryophyllene oxide (9.6%). This paper describes for the first time the composition of essential oils of S. lachnostachys and S. melissiflora.Colegio de Farmacéuticos de la Provincia de Buenos Aire

Contribuições da Sociologia na América Latina à imaginação sociológica: análise, crítica e compromisso social Sociology's contribution in Latin America to sociological imagination: analysis, critique, and social commitment

O artigo aborda o papel desempenhado pela Sociologia na análise dos processos de transformação das sociedades latino-americanas, no acompanhamento do processo de construção do Estado e da Nação, na problematização das questões sociais na América Latina. São analisados seis períodos na Sociologia na América Latina e no Caribe: I) a herança intelectual da Sociologia ; II) a sociologia da cátedra; III) O período da "Sociologia Científica" e a configuração da "Sociologia Crítica"; IV) a crise institucional, a consolidação da "Sociologia Crítica" e a diversificação da sociologia; V) a sociologia do autoritarismo, da democracia e da exclusão; VI) a consolidação institucional e a mundialização da sociologia da América Latina (desde o ano de 2000), podendo-se afirmar que os traços distintivos do saber sociológico no continente foram: o internacionalismo, o hibridismo, a abordagem crítica dos processos e conflitos das sociedades latino-americanas e o compromisso social do sociólogo.<br>The article focuses on the role played by Sociology in the analysis of processes of change in Latin American societies, in the process of construction of Nation and State, in the debate of social issues in Latin America and the Caribbean. Six periods in Sociology in Latin America and the Caribbean are examined: I) sociology's intellectual legacy; II) sociology as a cathedra; III) the period of "Scientific Sociology"; IV) the institutional crisis, the consolidation of "Critical Sociology", and the diversifying of sociology; V) sociology of authoritarianism, democracy and exclusion; VI) institutional consolidation and globalization of Latin American sociology (since 2000). It may be said that the distinctive features of sociological knowledge in the continent were: internationalism, hybridism, the critical approach to processes and conflicts of Latin American societies, and the sociologist social commitment

EAACI Molecular Allergology User's Guide 2.0

Since the discovery of immunoglobulin E (IgE) as a mediator of allergic diseases in 1967, our knowledge about the immunological mechanisms of IgE-mediated allergies has remarkably increased. In addition to understanding the immune response and clinical symptoms, allergy diagnosis and management depend strongly on the precise identification of the elicitors of the IgE-mediated allergic reaction. In the past four decades, innovations in bioscience and technology have facilitated the identification and production of well-defined, highly pure molecules for component-resolved diagnosis (CRD), allowing a personalized diagnosis and management of the allergic disease for individual patients. The first edition of the "EAACI Molecular Allergology User's Guide" (MAUG) in 2016 rapidly became a key reference for clinicians, scientists, and interested readers with a background in allergology, immunology, biology, and medicine. Nevertheless, the field of molecular allergology is moving fast, and after 6 years, a new EAACI Taskforce was established to provide an updated document. The Molecular Allergology User's Guide 2.0 summarizes state-of-the-art information on allergen molecules, their clinical relevance, and their application in diagnostic algorithms for clinical practice. It is designed for both, clinicians and scientists, guiding health care professionals through the overwhelming list of different allergen molecules available for testing. Further, it provides diagnostic algorithms on the clinical relevance of allergenic molecules and gives an overview of their biology, the basic mechanisms of test formats, and the application of tests to measure allergen exposure.Peer reviewe
