Anisotropic shock response of columnar nanocrystalline Cu
(AIP Publishing, 2010)
We perform molecular dynamics simulations to investigate the shock response of idealized hexagonal columnar nanocrystalline Cu, including plasticity, local shear, and spall damage during dynamic compression, release, and ...
Gene expression of the liver in response to chronic hypoxia.
Hypoxia is an important ecological, evolutionary, and biomedicalstressor. While physiological acclimatization of mammals to hypoxia is wellstudied, the variation in gene expression that underlies acclimatization is not ...
Hypoxia inactivates the VHL tumor suppressor through PIASy-mediated SUMO modification
The hypoxic microenvironment contributes to embryonic development and tumor progression through stabilization of the potent transcriptional factor HIF?. In normoxia, the tumor suppressor protein VHL acts as an E3 ubiquitin ...
Aging, depot origin, and preadipocyte gene expression.
Fat distribution changes with aging. Inherent changes in fat cell progenitors may contribute because fat cells turn over throughout life. To define mechanisms, gene expression was profiled in preadipocytes cultured from ...
MicroRNA expression in human airway smooth muscle cells: role of miR-25 in regulation of airway smooth muscle phenotype.
Defining mechanisms by which differentiated, contractile smooth muscle cells become proliferative and secretory in response to mechanical and environmental stress is crucial for determining the contribution of airway smooth ...
Functional genomics of mountain pine beetle (Dendroctonus ponderosae) midguts and fat bodies.
Background: The mountain pine beetle (Dendroctonus ponderosae) is a significant coniferous forest pest in western North America. It relies on aggregation pheromones to colonize hosts. Its three major pheromone components, ...
Using Automated Point Dendrometers to Analyze Tropical Treeline Stem Growth at Nevado de Colima, Mexico
The relationship between wood growth and environmental variability at the tropical treeline of North America was investigated using automated, solar-powered sensors (a meteorological station and two dendrometer clusters) ...
