Watermelon mosaic viruses 1 and 2 (WMV-1 and WMV-2) have both been collected in south and central Florida, but WMV-1 has been most prevalent in the southern and WMV-2 in the central counties. All WMV infections sampled from 1964 to 1969 in Collier and Hendry coun ties of south Florida were caused by WMV-1. Melothria pendula L., a native perennial cucurbitaceous weed, was found to be an over win...
OBJECTIVES Functional neuroimaging and voxel-based morphometry studies have confirmed the important role of the cerebellum in motor behavior. However, little is known about the relationship between cerebellar gray (GMv) and white matter (WMv) volume and manual motor performance in aging individuals. This study aims to quantify the relationship between cerebellar tissue volume and manual motor p...
BACKGROUND The aim of this study was to investigate potential morphological alterations of gray and white matter in patients with optic neuritis (ON) and their relationship with behavioral performance, using voxel-based morphometry (VBM). MATERIAL/METHODS Twelve (4 males, 8 females) patients with ON and 12 (4 males, 8 females) age-, sex-, and education-matched healthy controls (HCs) underwent...
ویروس موزاییک هندوانه (wmv) از جمله ویروس های مهمی است که در کدوئیان منجربه خسارت های زیادی می گردد. این ویروس دارای جدایه های مختلفی است که به لحاظ دامنه میزبانی، علائم و میزان خسارت با هم متفاوت می باشند. در این تحقیق دو جدایه متفاوت wmv به نام های wmv-41و wmv-55 از مزارع استان یزد جمع آوری و به لحاظ مولکولی و بیولوژیکی مورد مطالعه قرار گرفته اند. این جدایه ها بر خلاف سایر جدایه های این ویروس...
Dimensionality reduction procedures such as principal component analysis and the maximum margin criterion discriminant are special cases of a weighted maximum variance (WMV) approach. We present a simple two parameter version of WMV that we call 2P-WMV. We study the classification error given by the 1-nearest neighbor algorithm on features extracted by our and other dimensionality reduction met...
Microsoft Windows Media 9 Series is a set of technologies that enables rich digital media experiences across many types of networks and devices. These technologies are widely used in the industry for media delivery over the internet and other media, and are also applied to broadcast, high definition DVDs, and digital projection in theaters. At the core of these technologies is a state-of-the-ar...
The aim is to investigate the relationship between microstructural white matter (WM) diffusivity indices and macrostructural WM volume (WMV) among healthy individuals (20-85 years). Whole-brain diffusion measures were calculated from diffusion tensor imaging using FMRIB software library while WMV was estimated through voxel-based morphometry, and voxel-based analysis was carried out using tract...
To compare the difference in white matter volume (WMV) and gray matter volume (GMV) between the comitant strabismus (CS) patients and health controls by voxel-based morphometry (VBM) and the relationship with behavioral performance. A total of 20 patients with comitant strabismus (10 males and 10 females), and 20 healthy subjects (10 males and 10 females) with matched age, sex status underwent ...
The aim of the study was to find structural brain changes in systemic lupus erythematosus patients without major neuropsychiatric manifestations [non-neuropsychiatric systemic lupus erythematosus (non-NPSLE)] using quantitative magnetic resonance imaging (MRI) and possible associations with clinical characteristics. 89 non-NPSLE patients with normal conventional MRI and 84 healthy controls (HCs...
OBJECTIVE White matter atrophy occurs independently of lesions in multiple sclerosis. In contrast to lesion detection, the quantitative assessment of white matter atrophy in individual patients has been regarded as a major challenge. We therefore tested the hypothesis that white matter atrophy (WMA) is present at the very beginning of multiple sclerosis (MS) and in virtually each individual pat...
