Caracterização anatômica e perfi l químico da lâmina foliar de Laguncularia racemosa (L.) Gaertn, de manguezais impactados e não impactados do litoral de São Paulo

Anatomical characterization and chemical profi le of Laguncularia racemosa (L.) Gaertn leaf blades, from impacted and non-impacted mangroves of the São Paulo Coast. Several sources of environmental impact have caused great damage to the fl ora in mangroves. Therefore, this study aimed to analyze the anatomy and chemical composition of Laguncularia racemosa (L.) Gaertn leaf blades, from impacted (Municipality of Santos) and non-impacted mangroves (Municipality of Peruíbe) of the São Paulo Coast. For the leaf anatomy studies, light microscopy and scanning electron microscopy (SEM) were used. For chemical analysis, high performance liquid chromatography (HPLC) was conducted. The biometry revealed leaf tissues of plants from impacted mangroves with a less thick epidermis and mesophyll and higher width of the central vascular beam. A smaller number of stomata and higher amounts of druses in these leaves were also observed. Results were confi rmed by the Student t-test (α = 5%). The chemical profi les revealed a higher ammount of secondary metabolites in leaves from the impacted environment.

Espectalina, cassina e análogos semissintéticos como potenciais candidatos a fármacos para o tratamento da doença de Alzheimer

This paper describes the main steps in the study of Senna spectabilis, as part of our bioprospection studies, with the isolation of spectaline, cassine and other piperidine alkaloids, as well as the preparation of semi-synthetic analogues, and the studies of their pharmacological and toxicological properties, which led to the establishment of two candidate drugs for the treatment of Alzheimer disease.

Trabajo interdisciplinario para una óptima rehabilitación oral : caso clínico

Cuando pensamos en una rehabilitación oral estamos frente a una difícil situación, ya que esto involucra el compromiso de varias especialidades en forma simultánea. Esto es muy enriquecedor, un trabajo en equipo que para comenzar con el debate frente a las necesidades del plan de tratamiento, necesitará por encima de todo objetivos comunes y así poder arribar al objetivo final.
