PURPOSE: To determine whether optical imaging can be used for in vivo therapy response monitoring as an alternative to radionuclide techniques. For this, we evaluated the known Her2 response to 17-dimethylaminoethylamino-17-demethoxygeldanamycin …

Dyssynchronous myocardial motion aggravates cardiac pump function. Cardiac resynchronization using pacing devices is a standard-of-care in the management of heart failure. Post-infarction, however, scar tissue formation impedes the efficacy of …

Growing tumors are hypoxic and respond to microenvironmental stress through increased expression of the hypoxia inducible factor-1alpha (HIF-1alpha) transcription factor, resulting in an adaptive switch to glycolytic metabolism, angiogenic signaling, …

Early therapeutic efficacy of anti-death receptor 5 antibody (TRA-8) combined with gemcitabine was measured using diffusion-weighted magnetic resonance imaging (DWI) in an orthotopic pancreatic tumor model. Groups 1 to 4 of severe combined immunodeficient …

Recent evidence suggests that blockade of aberrant Hedgehog signaling can be exploited as a therapeutic strategy for pancreatic cancer. Our previous studies using the prototype Hedgehog small-molecule antagonist cyclopamine had shown the striking …

Pain: Noninvasive functional neurosurgery using ultrasound. …

In the past 15 years high-frequency B-mode sonography and colour-power Doppler have become the most important and most widely employed imaging modalities for the study of the neck, in particular for thyroid gland, parathyroids and lymph nodes. Sonography …

Muscle ultrasound is a useful tool in the diagnosis of neuromuscular disorders, as these disorders result in muscle atrophy and intramuscular fibrosis and fatty infiltration, which can be visualized with ultrasound. Several prospective studies have …

OBJECTIVES: The nerve ending problem is one of the major causes for diabetic feet. In this work, we explored the feasibilities of using high frequency ultrasound (US) in nerve ending problem evaluation for patients with diabetic foot. METHODS: The endings …

Fibrosis is a common late effect of radiotherapy treatment for cancer patients. Current clinical assessment of radiation-induced fibrosis is generally limited to clinician-based rating scales, which are usually not sufficient for quantitative and …
