BACKGROUND AND PURPOSE Nowadays the mechanism of homosexuality is little known. Few studies have been carried out to explore the brain functional changes of homosexual men during sexual arousal. We used functional MR imaging (fMRI) to determine whether the patterns of brain activation in homosexual and heterosexual men differed during visually evoked sexual(More)
Repetitive transcranial magnetic stimulation (rTMS) has been used as an investigative and therapeutic tool in neuropsychiatry and is advocated as a therapy for the treatment of psychiatric disorders, particularly adult depression. The therapeutic efficacy of current antidepressants applied to children or adolescents is unsatisfactory; thus innovative(More)
The underlying neurobiological factors involved in sexual orientation are largely unknown. This study investigated whether neural circuits or different cognitive processes accounted for differences in brain activation in 14 heterosexual and 14 homosexual males. Brain scans were undertaken in each subject using functional magnetic resonance imaging while(More)
BACKGROUND Although O(6)-methylguanine DNA methyltransferase (MGMT) promoter methylation status is an important marker for glioblastoma multiforme (GBM), there is considerable variability in the clinical outcome of patients with similar methylation profles. OBJECTIVE We examined whether a MicroRNA (miRNA) signature can be identified for predicting(More)
Objective: To develop a new method based on droplet digital PCR (DD-PCR) for detection and quantification of maternal cell contamination in prenatal diagnosis. Methods: Invasive prenatal samples from 40 couples of β(IVS-Ⅱ-654)/β(N) thalassemia gene carriers who accepted prenatal diagnosis in Affiliated Women and Children's Hospital of Guangzhou Medical(More)
