Mitochondrial respiration defects in cancer cells cause activation of Akt survival pathway through a redox-mediated mechanism
Cancer cells exhibit increased glycolysis for ATP production due, in part, to respiration injury (the Warburg effect). Because ATP generation through glycolysis is less efficient than throughExpand

Value added of teachers in high-poverty schools and lower poverty schools
Using student-level microdata from 2000–2001 to 2004–2005 from Florida and North Carolina, we compare the effectiveness of teachers in schools serving primarily students from low-income familiesExpand

Inhibition of glycolysis in cancer cells: a novel strategy to overcome drug resistance associated with mitochondrial respiratory defect and hypoxia.
Cancer cells generally exhibit increased glycolysis for ATP generation (the Warburg effect) due in part to mitochondrial respiration injury and hypoxia, which are frequently associated withExpand

Golden‐angle radial sparse parallel MRI: Combination of compressed sensing, parallel imaging, and golden‐angle radial sampling for fast and flexible dynamic volumetric MRI
TLDR
We develop a fast and flexible free‐breathing dynamic volumetric MRI technique, iterative Golden‐angle RAdial Sparse Parallel MRI (iGRASP), that combines compressed sensing, parallel imaging, and golden‐angle radial sampling. Expand

Inhibition of Mitochondrial Respiration
Cancer cells are under intrinsic increased oxidative stress and vulnerable to free radical-induced apoptosis. Here, we report a strategy to hinder mitochondrial electron transport and increaseExpand

What Makes Special-Education Teachers Special? Teacher Training and Acheivement of Students with Disabilities
Using statewide data from Florida, we analyze the impact of both pre-service and in-service training on the ability of teachers to promote academic achievement among students with disabilities. WeExpand

XD‐GRASP: Golden‐angle radial MRI with reconstruction of extra motion‐state dimensions using compressed sensing
TLDR
We develop a novel framework for free-breathing MRI called XD‐GRASP, which sorts dynamic data into extra motion‐state dimensions using the self‐navigation properties of radial imaging and reconstructs the multidimensional dataset using compressed sensing. Expand

Lysophosphatidic acid is constitutively produced by human peritoneal mesothelial cells and enhances adhesion, migration, and invasion of ovarian cancer cells.
Lysophosphatidic acid (LPA) is both a potential marker and a therapeutic target for ovarian cancer. It is critical to identify the sources of elevated LPA levels in ascites and blood of patients withExpand
