RATIONALE: Inhibitors of histone deacetylases (HDACs) reduce pressure-overload-induced left ventricular hypertrophy and dysfunction, but their effects on right ventricular (RV) adaptation to pressure overload are unknown. OBJECTIVES: Determine the effect …

Antisense oligonucleotide-mediated exon skipping is able to correct out-of-frame mutations in Duchenne muscular dystrophy and restore truncated yet functional dystrophins. However, its application is limited by low potency and inefficiency in systemic …

Spinophilin controls intensity/duration of G protein-coupled receptor signaling and thereby influences synaptic activity. We hypothesize that spinophilin affects blood pressure through central mechanisms. We measured blood pressure and heart rate in …

Recent studies showed that chronic administration of losartan, an angiotensin II type I receptor antagonist, improved skeletal muscle function in dystrophin-deficient mdx mice. In this study, C57BL/10ScSn-Dmd(mdx)/J female mice were either untreated or …

Purpose To noninvasively assess vascular hemodynamics with photoacoustic imaging (PAI) and blood oxygenation level-dependent (BOLD) magnetic resonance (MR) imaging in phantoms and in an animal model. Materials and Methods In vivo studies were performed …

The M-mode (motion mode) technique has improved the diagnostic possibilities of echocardiography due to its high temporal resolution. The use of a two-dimensional (2D) image as a basis for M-mode analysis at a defined line, independent of the transducer …

OBJECTIVE: Endothelium-dependent, flow-mediated vasodilation after an increase in shear stress at the endothelial lining of conduit arteries during reactive hyperemia after ischemia is a fundamental principle of vascular physiology adapting blood flow to …

Longitudinal studies of mouse cancer models required large cohorts since autopsy was the only reliable method to evaluate treatment efficacy. This paper reports the use of high-resolution three-dimensional ultrasound micro-imaging to monitor prostate …

Current prostate cancer research in both basic and preclinical trial studies employ genetically engineered mouse models. However, unlike in human prostate cancer patients, rodents have no counterpart of prostatic-specific antigen (PSA) for monitoring …

Androgen receptors have been shown to play a critical role in prostate cancer. We used ultrasound imaging techniques to track tumor response to antiandrogen and rapamycin treatment in a prostate-specific Pten-deleted mouse model of cancer. Depletion of …
