Effects of Human Mesenchymal Stem Cells Isolated from Wharton’s Jelly of the Umbilical Cord and Conditioned Media on Skeletal Muscle Regeneration Using a Myectomy Model

Stem Cells International, Volume 2014, Issue 1, 2014., 2014
Skeletal muscle has good regenerative capacity, but the extent of muscle injury and the developed fibrosis might prevent complete regeneration. The in vivo application of human mesenchymal stem cells (HMSCs) of the umbilical cord and the conditioned media (CM) where the HMSCs were cultured and expanded, associated with different vehicles to induce ...

Widespread negative effects of Leucaena leucocephala (white‐popinac) invasion on regenerating areas of the Atlantic Forest

Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
Fragment of Atlantic Forest (left) naturally regenerating in an abandoned pasture (centre) and being invaded by a large patch of white‐popinac (Leucaena leucocephala; right). This image summarizes the scenario of invasion by white‐popinac that is directly threatening forest regeneration and its native diversity.

Insights on the Potential of Natural Regeneration to Restore Cerrado Open Ecosystems

Austral Ecology, Volume 50, Issue 9, September 2025.
The colonisation potential of native Cerrado species in degraded areas will depend on the remaining underground structures and not on seed rain from nearby conserved remnants. Effective restoration of the Cerrado will not be possible without active restoration, if the bud‐bank are not present in the system.

Isolated Trees in a Fragmented Tropical Landscape: A View Through the Soil Seed Bank

Biotropica, Volume 57, Issue 5, September 2025.
Here, we investigated patterns of plant species diversity, abundance, and composition in the soil seed banks of cattle pastures, under fleshy‐fruited, and nonfleshy‐fruited trees within pastures, and in secondary forest patches at ten study sites in Brazil.

Tissue culture parameters in sweet orange cultivars Parâmetros de cultura de tecidos em cultivares de laranjeira-doce

Pesquisa Agropecuária Brasileira, 2008
The objective of this work was to establish tissue culture parameters for gene transfer in sweet orange cultivars. Epicotyl explants with different ages were cultured with 6-benzylaminopurine (BAP), kanamycin and hygromycin.

Impacts of fire on canopy structure and its resilience depend on successional stage in Amazonian secondary forests

Remote Sensing in Ecology and Conservation, Volume 11, Issue 4, Page 394-410, August 2025.
We analyzed the effects of fire on secondary forests' vertical structure in different successional stages using lidar metrics. Our results show that independently of the successional stage, secondary forests that experienced fire were more degraded than unburned secondary forest areas. Overall, our results show that forests in early successional stage (

A água e a vida

Tempo Social, 1993
Trata-se de exercício de interpretação da frase “tudo é água”, atribuída a Tales de Mileto. Depois da exposição dos pontos de vista do senso comum, da ciência e da filosofia sobre a utilidade da água para a vida, tenta-se recuperar, na dimensão simbólica,

The Rapid Recovery of a Caatinga Dry Forest is Mediated by Disturbance‐Adapted Species

Biotropica, Volume 57, Issue 4, July 2025.
Overall, regenerating and old‐growth forest stands exhibited similar plant diversity across all ontogenetic stages, with a negligible role played by forest stand age, precipitation, and chronic human disturbance. Species exclusively recorded as adults or seeds were mostly dispersed by animals, indicating that several species fail in either dispersing ...
