Cognitive function impacts gait, functional mobility and falls in fragile X-associated tremor/ataxia syndrome.

Executive function and information processing speed deficits occur in fragile X premutation carriers (PMC) with and without fragile X-associated tremor/ataxia syndrome (FXTAS). Gait is negatively impacted by cognitive deficits in many patient populations resulting in increased morbidity and falls but these relationships have not been studied in FXTAS.


FRAGILE X SYNDROME AND CONNECTIVE TISSUE CONNECTIVE TISSUE DEFICITS IN FRAGILE X SYNDROME.

Fragile X Syndrome is the most common cause of inherited intellectual disabilities and autism spectrum disorders and it is an X-linked disorder in which there is a deficiency of the Fragile X Mental Retardation 1 protein. This protein is crucial in regulating translation of mRNAs related to dendritic maturation and cognitive development. The phenotype of FXS is characterized by neurobehavioral alterations, social deficits, communication difficulties, and findings which suggest an alteration of connective ti...

Exemplar-based image completion using image depth information.

Image completion techniques are required to complete missing regions in digital images. A key challenge for image completion is keeping consistency of image structures without ambiguity and visual artifacts. We propose a novel method for image completion using image depth cue. Our method includes three major features. First, we compute the image gradient to improve image completion when searching for the most similar patches. Second, using image depth, we guide image completion by means of appropriate scale...


Repurposing available drugs for neurodevelopmental disorders: The fragile X experience.

Many available drugs have been repurposed as treatments for neurodevelopmental disorders. In the specific case of fragile X syndrome, many clinical trials of available drugs have been conducted with the goal of disease modification. In some cases, detailed understanding of basic disease mechanisms has guided the choice of drugs for clinical trials, and several notable successes in fragile X clinical trials have led to common use of drugs such as minocycline in routine medical practice. Newer technologies li...

Biobehavioral composite of social aspects of anxiety in young adults with fragile X syndrome contrasted to autism spectrum disorder.

Social anxiety is a common disorder that has negative impacts across multiple domains of function. Several clinical groups are at elevated risk for social anxiety, including those with fragile X syndrome and those with autism spectrum disorder. Measuring social anxiety in these clinical subgroups is fraught with challenge, however, given the complexity of social anxiety and measurement limitations that are particularly acute in persons with neurodevelopmental disorders. The over-arching aim of this study wa...

Readout models for BaFBrI:Eu image plates.

The linearity of the photostimulated luminescence process makes repeated image-plate scanning a viable technique to extract a more dynamic range. In order to obtain a response estimate, two semi-empirical models for the readout fading of an image plate are introduced; they relate the depth distribution of activated photostimulated luminescence centers within an image plate to the recorded signal. Model parameters are estimated from image-plate scan series with BAS-MS image plates and the Typhoon FLA 7000 sc...

Learning a Convolutional Neural Network for Image Compact-Resolution.

We study the dual problem of image superresolution (SR), which we term image compact-resolution (CR). Opposite to image SR that hallucinates a visually plausible highresolution image given a low-resolution input, image CR provides a low-resolution version of a high-resolution image, such that the low-resolution version is both visually pleasing and as informative as possible compared to the high-resolution image. We propose a convolutional neural network (CNN) for image CR, namely CNN-CR, inspired by the gr...

Gamma oscillations in cognitive disorders.

Gamma oscillations (∼25-100 Hz) are believed to play a role in cognition. Accordingly, aberrant gamma oscillations have been observed in several cognitive disorders, including Alzheimer's disease and Fragile X syndrome. Here, we review how recent results showing abnormal gamma rhythms in Alzheimer's disease and Fragile X syndrome help reveal links between cellular disturbances and cognitive impairments. We also discuss how gamma results from rodent models of Alzheimer's disease and Fragile X syndrome ma...

Metformin for Treatment of Fragile X Syndrome and Other Neurological Disorders.

Fragile X syndrome (FXS) is the most frequent inherited form of intellectual disability and autism spectrum disorder. Loss of the fragile X mental retardation protein, FMRP, engenders molecular, behavioral, and cognitive deficits in FXS patients. Experiments using different animal models advanced our knowledge of the pathophysiology of FXS and led to the discovery of many targets for drug treatments. In this review, we discuss the potential of metformin, an antidiabetic drug approved by the US Food and Drug...

Fragile Topology and Wannier Obstructions.

Topological phases, such as Chern insulators, are defined in terms of additive indices that are stable against the addition of trivial degrees of freedom. Such topology presents an obstruction to any Wannier representation, namely, the representation of the electronic states in terms of symmetric, exponentially localized Wannier functions. Here, we address the converse question: Do obstructions to Wannier representation imply stable band topology? We answer this in the negative, pointing out that some bands...

Monocular Ghost Image Offset Thresholds: Dependent on Target Size and Ghost Image Relative Brightness.

This is the first report of monocular ghost image offset thresholds measured using O optotypes. Monocular diplopia is a complaint of patients and is the result of a variety of etiologies. Furthermore, monocular image doubling also can be a confounding variable of vectographic stereoacuity tests, warranting an investigation of ghost image offset thresholds.

Metabolic pathways modulate the neuronal toxicity associated with Fragile X-Associated Tremor/Ataxia Syndrome.

Fragile X-Associated Tremor/Ataxia Syndrome (FXTAS) is an adult-onset neurodegenerative disorder that affects premutation carriers (55-200 CGG repeats) of the Fragile X Mental Retardation 1 (FMR1) gene. Much remains unknown regarding the metabolic alterations associated with FXTAS, especially in the brain, and the most affected region, the cerebellum. Investigating the metabolic changes in FXTAS will aid in the identification of biomarkers as well as in understanding the pathogenesis of disease. To identify...

Image Deblurring with a Class-Specific Prior.

A fundamental problem in image deblurring is to reliably recover distinct spatial frequencies that have been suppressed by the blur kernel. To tackle this issue, existing image deblurring techniques often rely on generic image priors such as the sparsity of salient features including image gradients and edges. However, these priors only help recover part of the frequency spectrum, such as the frequencies near the high-end. To this end, we pose the following specific questions: (i) Does any image class infor...

Non-weight-related body image concerns and Body Dysmorphic Disorder prevalence in patients with Anorexia Nervosa.

Patients with Anorexia Nervosa (AN) and patients with Body Dysmorphic Disorder (BDD) are both characterized by body image disturbance and dissatisfaction; furthermore, these disorders share clinical features and frequently co-occur. However, few studies have explored the relation between AN and BDD. Therefore, the first aim of the study was assessing the prevalence of BDD and presence of non-weight-related body image concerns in patients with AN. Second, we were interested in comparing patients with AN and ...

Photo Realistic Image Completion via Dense Correspondence.

In this paper, we propose an image completion algorithm based on dense correspondence between the input image and an exemplar image retrieved from Internet. Contrary to traditional methods which register two images according to sparse correspondence, in this paper we propose a hierarchical PatchMatch method that progressively estimates a dense correspondence which is able to capture small deformations between images. The estimated dense correspondence has usually large occlusion areas that correspond to the...

Divide and Count: Generic Object Counting by Image Divisions.

We propose a general object counting method that does not use any prior category information. We learn from local image divisions to predict global image-level counts without using any form of local annotations. Our method separates the input image into a sets of image divisions - each fully covering the image. Each image division is composed of a set of region proposals or uniform grid cells. Our approach learns in an endto- end deep learning architecture to predict global image-level counts from local ima...

Visual attention mechanism and support vector machine based automatic image annotation.

Automatic image annotation not only has the efficiency of text-based image retrieval but also achieves the accuracy of content-based image retrieval. Users of annotated images can locate images they want to search by providing keywords. Currently most automatic image annotation algorithms do not consider the relative importance of each region in the image, and some algorithms extract the image features as a whole. This makes it difficult for annotation words to reflect salient versus non-salient areas of th...

High-speed image-reconstruction algorithm for a spatially multiplexed image and application to digital holography.

We propose a high-speed image-reconstruction algorithm for a spatially multiplexed image that is obtained by spatial frequency-division multiplexing. The algorithm utilizes smoothing and does not require any Fourier transform (FT) or iterative procedure to extract the desired information selectively from a single image. Numerical and experimental results show its validity and color holographic imaging ability. Calculation time of the proposed is less than a tenth of that of the FT method when using a centra...

Expressed emotion and impulsiveness in mothers of children with Fragile X Syndrome and Down Syndrome: The relation to behavioral problems in their offspring.

Fragile X Syndrome (FXS) and Down Syndrome (DS) are common causes of Intellectual Disability (ID). Mothers of individuals with FXS sometimes have the premutation condition which makes them display neurocognitive signs, such as impulsiveness impairments, while mothers of DS individuals, as a group, do not have impairments. Although behavior problems in individuals with ID may be related to high Expressed Emotion (EE) in parents, parenting in families with ID members has been little explored.

L0-Regularized Image Downscaling.

In this paper, we propose a novel L0-regularized optimization framework for image downscaling. The optimization is driven by two L0-regularized priors. The first prior, gradientratio prior, is based on the observation that the number of edges in the downscaled image is approximately inverse square proportional to the downscaling factor. By introducing L0 norm sparsity to the gradient ratio, the downscaled image is able to preserve the most salient edges as well as the visual perception of the original image...

Author Correction: Yolk sac macrophage progenitors traffic to the embryo during defined stages of development.

This article contains errors in Figs. 5 and 6, for which we apologize. In Fig. 5f, the image 'E12.5 tail' was inadvertently replaced with a duplicate of the image 'E12.5 trunk' from the same panel. In Figure 6d, the image 'E9.5/OH-TAM E8.5, embryo' was inadvertently replaced with a duplicate of the image 'E10.5/ OH-TAM E8.5, embryo' from Fig. 6b. The corrected versions of these figures appear in the Author Correction associated with this Article.

Image segmentation by graph cut for radiation images of small animal blood vessels.

Synchrotron radiation (SR) based X-ray imaging is an attractive method for analyzing biomedical structure. However, despite its many advantages, there are few gold standards in image processing methods, especially in segmentation. Image segmentation is an essential step in medical imaging for image analysis and three-dimensional reconstruction. Although there are many algorithms for image segmentation, a decisive method does not exist in SR X-ray imagery, because of a lack of data. This study focused on fin...

Image retargeting via Beltrami representation.

Image retargeting aims to resize an image to one with a prescribed aspect ratio. Simple scaling inevitably introduces unnatural geometric distortions on the important content of the image. In this paper, we propose a simple and yet effective method to resize an image, which preserves the geometry of the important content, using the Beltrami representation. Our algorithm allows users to interactively label content regions as well as line structures. Image resizing can then be achieved by warping the image by...

Image categorization from functional magnetic resonance imaging using functional connectivity.

Previous studies have attempted to infer the category of objects in a stimulus image from functional magnetic resonance imaging (fMRI) data recoded during image-viewing. Most studies focus on extracting activity patterns within a given region or across multiple voxels, and utilize the relationships among voxels to decipher the category of a stimulus image. Yet, the functional connectivity (FC) patterns across regions of interest in response to image categories, and their potential contributions to category ...
