1. Caracterização do micro-habitat dos ninhos e predação dos ovos de Podocnemis erythrocephala em áreas de desova no Rio Ayuanã, AM
Os quelônios de família Podocnemidae são uma importante fonte de proteína para as populações ribeirinhas da Amazônia. O comércio ilegal tem exercido pressão sobre as populações de quelônios ameaçando populações locais. Podocnemis erythrocephala, que ocorre quase que restritamente em águas pretas, tem sido consumida por estas populações há

2. Shape transition during nest digging in ants
Nest building in social insects is among the collective processes that show highly conservative features such as basic modules (chambers and galleries) or homeostatic properties. Although ant nests share common characteristics, they exhibit a high structural variability, of which morphogenesis and underlying mechanisms remain largely unknown. We conducted tw

3. Chronic growth stimulation of human adult melanocytes by inflammatory mediators in vitro: implications for nevus formation and initial steps in melanocyte oncogenesis.
In the human epidermis, melanocytes are distributed at a distance from each other. In contrast, melanocytes in nevi, which are considered benign neoplasms of melanocytes, are grouped in nests. Although still not well defined, environmental factors are thought to play an important role in the development of nevi. We found that chronic growth stimulation by le
