Tumor microvasculature possesses a high degree of heterogeneity in its structure and function. These features have been demonstrated to be important for disease diagnosis, response assessment, and treatment planning. The exploratory efforts of quantifying tumor vascular heterogeneity with DCE-MRI have led to promising results in a number of studies.(More)
Relaxometric measurement of the effective transverse relaxation rate R2* plays an important role in the quantitative evaluation of brain function, perfusion, and tissue iron content. However, accurate measurement of R2* is prone to macroscopic background field inhomogeneity. In clinical applications and systems, postprocessing correction techniques are more(More)
OBJECTIVES In the present study, we investigated the role of adenosine triphosphate (ATP)-sensitive potassium (KATP) channels in chronic morphine tolerance. MATERIALS AND METHODS Male mice were injected intrathecally with morphine or saline, respectively (each in 10 μL). Different doses of the KATP opener cromakalim (0.3, 1, or 3 μg/10 μL/mouse) were(More)
INTRODUCTION The neurophysiological basis of pain relief due to spinal cord stimulation (SCS) and the related cortical processing of sensory information are not completely understood. The aim of this study was to use resting state functional magnetic resonance imaging (rs-fMRI) to detect changes in cortical networks and cortical processing related to the(More)
AIMS/INTRODUCTION To clarify the association of the hypertriglyceridemic waist phenotype and type 2 diabetes mellitus among adults in China. MATERIALS AND METHODS In the present case-control study, we included 1,685 patients with type 2 diabetes mellitus and 7,141 normal glucose-tolerant controls from the Henan Province of China in 2011. Elevated waist(More)
Some global models to predict the risk of diabetes may not be applicable to local populations. We aimed to develop and validate a score to predict type 2 diabetes mellitus (T2DM) in a rural adult Chinese population. Data for a cohort of 12,849 participants were randomly divided into derivation (n = 11,564) and validation (n = 1285) datasets. A questionnaire(More)
Photodynamic therapy (PDT) is an efficacious treatment for some types of cancers. However, PDT-induced tumor hypoxia as a result of oxygen consumption and vascular damage can reduce the efficacy of this therapy. Measuring and monitoring intrinsic and PDT-induced tumor hypoxia in vivo during PDT is of high interest for prognostic and treatment evaluation. In(More)
