Desenvolvimento e controle de qualidade físico e microbiológico de emulsão O/A contendo óleo essencial de Melaleuca alternifolia

Sabe-se que na atualidade, é grande a preocupação da comunidade científica mundial, em relação à resistência microbiana frente às substâncias convencionais, utilizadas indiscriminadamente, por isso, é crescente a motivação da pesquisa básica na bioprospecção de novas substâncias, que apresentem atividade antimicrobiana e antifúngica e que possam ser uma alternativa segura e eficaz contra esses microorganismos no tratamento das doenças causadas por eles. As dermatofitoses, por exemplo, são processos infecciosos de pele, pêlo e unhas que acometem muitas pessoas, de todas as faixas etárias, no mundo todo, provocando as chamadas tinhas ou tineas, denominadas corporis, pedis, cruris, capitis, unguium(onicomicose) e outras (dependendo o local do corpo onde estão), causadas pelo dermatófito filamentoso, Trichophyton rubrum. Estudos envolvendo este patógeno são cada vez mais importantes, devido ao aparecimento de linhagens resistentes aos medicamentos antifúngicos disponíveis no mercado, e ao comportamento invasivo deste agente em pacientes com o sistema imune comprometido. Porém, somente a descoberta de novas drogas não é suficiente, é preciso desenvolver produtos eficazes e seguros, que possam veicular essas substâncias sem causar prejuízo ao paciente. Sendo assim, a proposta desse trabalho é desenvolver uma emulsão A/O, contendo óleo essencial de Melaleuca alternifolia (TTO), verificar sua estabilidade preliminar e caracterizá-la realizando o estudo reológico da formulação, determinar a concentração inibitória mínima (CIM) e a concentração fungicida mínima (CFM) do TTO e averiguar a atividade antifúngica in vitro da emulsão frente ao T. rubrum, agente patogênico ao qual se destina o uso do produto

Professor Emeritus Leo G Carney Optometry's quiet achiever

Perhaps more than any other sub-discipline in optometry and vision science, the academic field of cornea and contact lenses is populated by an assortment of extroverted and flamboyant characters who constantly travel the world, entertaining clinicians with dazzling audiovisual presentations, informing them about the latest advances in the field and generally promoting their own scientific agendas. The antithesis of this is Leo Carney (Figure 1), a highly accomplished researcher, teacher, mentor and administrator, who has quietly and with great dignity carved out an impressive career in academic optometry. Indeed, Leo Carney is optometry's quintessential ‘quiet achiever’

Melaleuca densispicata in Currawinya National Park, South-West Queensland: Ecology and preliminary implications for management of a rare plant species

Melaleuca densispicata Byrnes is an uncommon species with a limited distribution, comprising disjunct populations in inland southern Queensland and northern New South Wales, Australia. It is a dense, woody shrub, 2–4 m in height, which exhibits a marked 'clumping' growth habit. It has thick, papery bark and displays many white flowers during spring or early summer. Although it has long been known to exist, M. densispicata was only formally described in 1984, and very little is currently known about its ecology or specific management requirements. There are only seven known subpopulations of the species across its range. A major population at the western limit of its distribution occurs on Currawinya National Park (28°52'S, 144°30'E). Here, it is locally abundant and listed as a noteworthy plant species under the Management Plan (Queensland Parks & Wildlife Service 2001). This study aimed to identify patterns in the distribution of M. densispicata in Currawinya National Park, describe its ecological niche and role, and provide management recommendations for the species within the study area. Recent anecdotal observations of recruitment failure in south-western Queensland (Peter McRae, QPWS, October 2004, pers. comm.; Dick O'Connell, local grazier, July 2005 pers. comm.) caused additional emphasis to be placed on the examination of recruitment and recruitment factors.
