Intracultural Variation in the Knowledge of Medicinal Plants in an Urban‐Rural Community in the Atlantic Forest from Northeastern Brazil

Evidence-Based Complementary and Alternative Medicine, Volume 2012, Issue 1, 2012., 2012
This study assessed the intracultural knowledge of the use of medicinal plants in an urban‐rural community in an Atlantic forest fragment in northeastern Brazil. We examined the importance of native and exotic species and the effects of gender and age on that knowledge.

Mecanismos de controle de tolerância à dissecação em sementes de Caesalpinia echinata LAM. (Pau-Brasil) e Caesalpinia peltophoroides BENTH. (Sibipiruna)

, 2010
A aquisição da tolerância à dessecação ocorre durante a maturação da semente, após acúmulo de reservas e antes do início do processo natural de secagem, porém, com o avanço da germinação a sensibilidade a dessecação aumenta.

Glycosaminoglycans Modify Elastase Action In Vitro and Enhance Elastase‐Induced Cell Death in Cultured Fibroblasts

International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
Human neutrophil elastase (HNE) has been shown to be involved on death of different cell types, including epithelial lung cells, which is related to several pulmonary diseases. Since HNE activity may be influenced by extracellular matrix (ECM) molecules such as glycosaminoglycans (GAGs), and fibroblasts are the most common ECM‐producing cells of lung ...

Environmental Factors Influencing Foraging Activity in the Social Wasp Polybia paulista (Hymenoptera: Vespidae: Epiponini)

Psyche: A Journal of Entomology, Volume 2011, Issue 1, 2011., 2011
Foraging behavior in social wasps is important in the development of the colony and reflects an important ecological interaction between the colony and the environment. Although the social traits of the colony play a role in the foraging activities, the conditions that establish the space and time limits are mainly physical.
