It is well known that iron accumulates in the brains of patients with various neurodegenerative diseases. To better understand disease-related iron changes, it is necessary to know the physiological distribution and accumulation of iron in the human brain. Studies have shown that brain iron levels increase with aging. However, the effects of gender and(More)
Recent imaging studies have shown that brain morphology and neural activity during sexual arousal differ between homosexual and heterosexual men. However, functional differences in neural networks at the resting state is unknown. The study is to characterize the association of homosexual preference with measures of regional homogeneity and functional(More)
INTRODUCTION Neuroimaging studies have reported differences in brain structure and function between homosexual and heterosexual men. The neural basis for homosexual orientation, however, is still unknown. AIM This study characterized the association of homosexual preference with measures of fractional amplitude of low-frequency fluctuation (fALFF) and(More)
Few studies demonstrated neural circuits related to disgust were influenced by internal sexual orientation in male. Here we used fMRI to study the neural responses to disgust in homosexual and heterosexual men to investigate that issue. Thirty-two healthy male volunteers (sixteen homosexual and sixteen heterosexual) were scanned while viewing alternating(More)
Zooplankton is generally affected by both top-down and bottom-up regulations in aquatic ecosystems. However, the relative strength of top-down and bottom-up controls on zooplankton assemblages is not well understood. Here, we analyzed this question in five lakes of the Yangtze River basin, an area with high population density and thousands of lakes, many of(More)
INTRODUCTION This study aims to evaluate the impact of iron deposition during aging on the measurement of water diffusion in the brain. METHODS Diffusion tensor images (DTI) and phase images collected from a group of healthy adults from 23 to 72 years old were retrospectively analyzed. The axial diffusivity, radial diffusivity, mean diffusivity (MD), and(More)
Membranous nephropathy (MN) is the major cause of adult nephrotic syndrome, which severely affects patients' quality of life. Currently, percutaneous renal biopsy is required to definitively diagnose MN. However, this technique is invasive and may cause severe complications. Therefore, an urgent clinical need exists for dynamic noninvasive monitoring of the(More)
BACKGROUND Ischemic stroke and glioblastoma multiforme have similar features on anatomic magnetic resonance imaging (MRI) and thus may require a surgical biopsy for a definitive diagnosis. CASE PRESENTATION A 55-year-old male complained of dysphasia for 4 weeks and continuous deterioration for 5 days. Cerebral infarction was considered based on MRI, which(More)
BACKGROUND Acute rejection (AR) and acute tubular necrosis (ATN) are main causes of early renal allograft dysfunction. Blood oxygen level-dependent magnetic resonance imaging (BOLD MRI) and Diffusion weighted (DW) MRI can provide valuable information about changes of oxygen bioavailability and water diffusion by measuring R2* or apparent diffusion(More)
