We measured c-fos messenger RNA levels and Fos protein immunoreactivity in the suprachiasmatic nucleus of rats as a function of light and time of day. Immunohistochemistry demonstrated a daily rhythm of immunoreactive Fos in the ventrolateral subdivision of the suprachiasmatic nucleus of animals entrained to a 12 h/12 h light-dark cycle; expression was low(More)
Irreversible electroporation (IRE) is a non-thermal focal ablation technique that uses a series of brief but intense electric pulses delivered into a targeted region of tissue, killing the cells by irrecoverably disrupting cellular membrane integrity. This study investigates if there is an improved local anti-tumor response in immunocompetent (IC) BALB/c(More)
Understanding the mechanisms of cellular internalization is necessary for rational design of efficient polymers for DNA delivery. In this paper, we present evidence that poly(glycoamidoamine) (PGAA)-DNA complexes (polyplexes) interact with cell-surface glycosaminoglycans (GAGs) in a manner that is not solely dependent on charge. The presence of GAGs appears(More)
Heterodyne interferometry and phase contrast imaging (PCI) are robust, mature techniques for measuring low-k and high-k electron density fluctuations, respectively. This work describes the first-ever implementation of a combined PCI-interferometer. The combined system uses a single 10.6 μm probe beam, two interference schemes, and two detectors to measure(More)
