CONTEXT Most of what we know about antipsychotic drug effects is at the receptor level, distal from the neural system effects that mediate their clinical efficacy. Studying cerebral function in antipsychotic-naive patients with schizophrenia before and after pharmacotherapy can enhance understanding of the therapeutic mechanisms of these clinically(More)
BACKGROUND Previous structural imaging studies found evidence of brain morphometric changes in major depression (MD) patients, but they rarely excluded compounding effects of some important factors, such as medication and brain degeneration. This study sought to explore the brain morphometric changes of first-episode, drug-naïve, non-late-life adult MD(More)
OBJECTIVE The purpose of the present study was to characterize the association between clinical symptoms and anatomical and functional cerebral deficits in a relatively large sample of antipsychotic-naive first-episode schizophrenia patients using optimized voxel-based morphometry and resting state functional connectivity analysis. METHOD Participants(More)
To explore the real association between p53 codon 72 polymorphism and lung cancer risk, a pooled analysis of 32 case–control studies involving 19,255 subjects was conducted. When all 32 studies were pooled into the analysis, significantly elevated lung cancer risks were associated with variant genotypes in all genetic models (for Pro/Arg vs. Arg/Arg: OR(More)
The purpose of this study was to assess volumetric abnormalities of gray matter throughout the entire brain in patients with paranoid schizophrenia or with bipolar mania compared with control groups. We obtained weighted 3D T1 magnetic resonance images from 23 patients with paranoid schizophrenia, 24 patients with psychotic bipolar mania, and 36 healthy(More)
In this paper, a method for measuring the perceptual image quality of JPEG-2000 coded images has been proposed. The image quality is characterized by the average edgespread in the image, or more specifically the average extent of the slope’s spread of an edge in the opposing gradients’ directions. The proposed method is, in effect, a way of measuring the(More)
OBJECTIVES Structural abnormality of both gray and white matter has been detected in patients with bipolar disorder (BD). But results were greatly inconsistent across studies which were most likely attributed to heterogeneous populations as well as processing techniques. The present study aimed to investigate brain structural and microstructural alterations(More)
We thank authors of the comment for their interest in our paper. Due to our careless, one condition was not presented at the first step of our algorithm in the published version. However, the idea of the algorithm and the given example are all correct, as they are all actually based on the correct and complete conditions. Here we provide a supplement to the(More)
