Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the brain. Although measurements of GABA levels in vivo in the human brain using edited proton magnetic resonance spectroscopy ((1)H-MRS) have been established for some time, it is has not been established how regional GABA levels vary with age in the normal human brain. In this(More)
The purpose of this study was to analyze the impact of vanadium absorbed by Coprinus comatus (VACC) on fracture healing in streptozotocin-diabetic rats. Forty-five male Wistar rats used were divided into three groups: normal rats (control), diabetic rats, and diabetic rats treated with VACC. A standardized fracture-healing model with a stable plate fixation(More)
OBJECTIVES To prospectively evaluate the impact of 3.0 T Cardiac MR imaging using dual-source parallel radiofrequency (RF) transmission with patient-adaptive B1 shimming compared with single-source RF transmission in the RF homogeneity, image contrast and image quality. METHODS The study was approved by the local institutional review board, and all(More)
Accumulating evidence has shown that microRNAs are involved in multiple processes in cancer development and progression. Recent studies have shown that miR-23a functions as an oncogene in various human cancer types, but its role in osteosarcoma remains poorly understood. Here, we demonstrated that miR-23a is frequently downregulated in osteosarcoma(More)
To explore the handedness effects on phase asymmetries in deep gray matter of healthy adults by using magnetic susceptibility-weighted imaging (SWI) phase. Thirty left-handed (16 men, 14 women; age range, 20 to 57 years) and 30 age- and sex-matched right-handed (16 men, 14 women; age range, 20 to 58 years) healthy adults were examined at 3.0 T MRI. For each(More)
— In order to better identify the fault of rotor system,one new method based on local fuzzy clustering margin fisher discriminant (LFCMFD) was proposed. For each point on manifold, the farthest point in local neighborhood and the nearest point outside local neighborhood usually constituted the local margin. LFCMFD introduced fuzzy cluster analysis(More)
Increasing evidence has suggested that the GABAergic neurotransmitter system is involved in the pathogenesis of premenstrual dysphoric disorder (PMDD). We used proton magnetic resonance spectroscopy ((1)H MRS) to investigate whether PMDD is associated with alterations in brain GABA levels. Levels of glutamate-glutamine (Glx) were also explored.

BACKGROUND T1ρ and T2* relaxation times are capable of providing information about early biochemical changes in intervertebral disk degeneration (IVDD). The purpose of this study was to assess and compare T1ρ and T2* mapping in IVDD with reference to Pfirrmann grade. MATERIAL AND METHODS Lumbar sagittal T2-weighted, T1ρ and T2* relaxation MRI were(More)
