M-HIFU inhibits tumor growth, suppresses STAT3 activity and enhances tumor specific immunity in a transplant tumor model of prostate cancer.
(PLoS One, 2012)OBJECTIVE: In this study, we explored the use of mechanical high intensity focused ultrasound (M-HIFU) as a neo-adjuvant therapy prior to surgical resection of the primary tumor. We also investigated the role of signal transducer ... -
Macrophage cells secrete factors including LRP1 that orchestrate the rejuvenation of bone repair in mice.
(Nature communications, 2018-12-05)The pace of repair declines with age and, while exposure to a young circulation can rejuvenate fracture repair, the cell types and factors responsible for rejuvenation are unknown. Here we report that young macrophage cells ... -
Macrosystems ecology: Understanding ecological patterns and processes at continental scales
(Frontiers in Ecology and the Environment, 2014-02-01)Macrosystems ecology is the study of diverse ecological phenomena at the scale of regions to continents and their interactions with phenomena at other scales. This emerging subdiscipline addresses ecological questions and ... -
Magic moment? Maternal marriage for children born out of wedlock.
(Demography, 2014-08)To test the existence of the "magic moment" for parental marriage immediately post-birth and to inform policies that preferentially encourage biological over step parent marriage, this study estimates the incidence and stability ... -
Magnesian inviolability
(Transactions of the American Philological Association, 2009-09-01)In 221/20 the citizens of Magnesia on the Maeander sought to create crowned games in honor of Artemis Leukophryene. The goddess had appeared to them and Delphi instructed that "it is more agreeable and better for those who ... -
Magnetic levitation of metamaterial bodies enhanced with magnetostatic surface resonances
(Physical Review B - Condensed Matter and Materials Physics, 2012-02-27)We propose that macroscopic objects built from negative-permeability metamaterials may experience resonantly enhanced magnetic force in low-frequency magnetic fields. Resonant enhancement of the time-averaged force originates ... -
Magnetic metamaterial superlens for increased range wireless power transfer.
(Sci Rep, 2014-01-10)The ability to wirelessly power electrical devices is becoming of greater urgency as a component of energy conservation and sustainability efforts. Due to health and safety concerns, most wireless power transfer (WPT) schemes ... -
Magnetic resonance imaging of graded skeletal muscle injury in live rats.
(Environ Health Insights, 2014)INTRODUCTION: Increasing number of stretch-shortening contractions (SSCs) results in increased muscle injury. METHODS: Fischer Hybrid rats were acutely exposed to an increasing number of SSCs in vivo using a custom-designed ... -
Magnetic resonance microscopy.
(Anal Cell Pathol (Amst), 2012) -
Magnetic resonance water proton relaxation in protein solutions and tissue: T(1rho) dispersion characterization.
(PLoS One, 2010-01-05)BACKGROUND: Image contrast in clinical MRI is often determined by differences in tissue water proton relaxation behavior. However, many aspects of water proton relaxation in complex biological media, such as protein solutions ... -
Magnetic superlens-enhanced inductive coupling for wireless power transfer
(Journal of Applied Physics, 2012-03-15)We investigate numerically the use of a negative-permeability perfect lens for enhancing wireless power transfer between two current carrying coils. The negative permeability slab serves to focus the flux generated in the ... -
Magnetically tunable self-assembly of colloidal rings
(Applied Physics Letters, 2010-08-23)We present a technique using ferrofluid to induce bidisperse suspensions of superparamagnetic and diamagnetic beads to assemble into colloidal ring configurations. The separation distance between particles within the ring ... -
Magnetophoretic circuits for digital control of single particles and cells.
(Nat Commun, 2014-05-14)The ability to manipulate small fluid droplets, colloidal particles and single cells with the precision and parallelization of modern-day computer hardware has profound applications for biochemical detection, gene sequencing, ... -
Magnitude and breadth of a nonprotective neutralizing antibody response in an efficacy trial of a candidate HIV-1 gp120 vaccine.
(J Infect Dis, 2010-08-15)BACKGROUND: A candidate vaccine consisting of human immunodeficiency virus type 1 (HIV-1) subunit gp120 protein was found previously to be nonprotective in an efficacy trial (Vax004) despite strong antibody responses against ... -
Magnitude of spinal muscle damage is not statistically associated with exercise-induced low back pain intensity.
(Spine J, 2011-12)BACKGROUND CONTEXT: Findings on imaging of noncontractile anatomic abnormalities and the intensity of low back pain have weak associations because of false-positive rates among asymptomatic individuals. This association ... -
Mainland size variation informs predictive models of exceptional insular body size change in rodents.
(Proc Biol Sci, 2015-07-07)The tendency for island populations of mammalian taxa to diverge in body size from their mainland counterparts consistently in particular directions is both impressive for its regularity and, especially among rodents, troublesome ... -
Maintenance and neuronal differentiation of chicken induced pluripotent stem-like cells.
(Stem Cells Int, 2014)Pluripotent stem cells have the potential to become any cell in the adult body, including neurons and glia. Avian stem cells could be used to study questions, like vocal learning, that would be difficult to examine with ... -
Major and minor music compared to excited and subdued speech.
(J Acoust Soc Am, 2010-01)The affective impact of music arises from a variety of factors, including intensity, tempo, rhythm, and tonal relationships. The emotional coloring evoked by intensity, tempo, and rhythm appears to arise from association ... -
Making genomic medicine evidence-based and patient-centered: a structured review and landscape analysis of comparative effectiveness research.
(Genet Med, 2017-04-13)Comparative effectiveness research (CER) in genomic medicine (GM) measures the clinical utility of using genomic information to guide clinical care in comparison to appropriate alternatives. We summarized findings of high-quality ...
