Comparative Analysis of CNN and RNN for Voice Pathology Detection

Diagnosis on the basis of a computerized acoustic examination may play an incredibly important role in early diagnosis and in monitoring and even improving effective pathological speech diagnostics. Various acoustic metrics test the health of the voice. The precision of these parameters also has to do with algorithms for the detection of speech noise. The idea is to detect the disease pathology from the voice. First, we apply the feature extraction on the SVD dataset. After the feature extraction, the system input goes into the 27 neuronal layer neural networks that are convolutional and recurrent neural network. We divided the dataset into training and testing, and after 10 k-fold validation, the reported accuracies of CNN and RNN are 87.11% and 86.52%, respectively. A 10-fold cross-validation is used to evaluate the performance of the classifier. On a Linux workstation with one NVidia Titan X GPU, program code was written in Python using the TensorFlow package.

Zbed3 Is Indispensable for Wnt Signaling Regulation of Cortical Layers Formation in Developing Brain

Wnt/β-catenin signaling plays multiple important roles during mammalian brain development, and it regulates the proliferation and differentiation of neural progenitors in a context-dependent manner and affects neocortex layer formation. However, the specific role of Wnt/β-catenin in neuronal layer fate determination in the neocortex is still unclear. Here, we report that Zbed3, which is a positive regulator of Wnt/β-catenin signaling, colocalizes with β-catenin at the endfeet of radial glia in the ventricular zone of embryo mouse neocortex. Overexpression and knockdown of Zbed3 increased and decreased the activity of Wnt/β-catenin signaling in the neocortex, respectively. Interestingly, knockdown of Zbed3 in vivo could significantly shift neuronal fates from deep layers to upper layers but is not required for the proliferation and differentiation of neural progenitors. Overexpression of Zbed3 led to increased generation of deep-layer neurons without impairing cell cycle exit of neural progenitors. More importantly, knockdown of Zbed3 could effectively block the effects of the ectopic expression of stabilized β-catenin on neocortex layer formation. Hence, our results demonstrate that Zbed3 is indispensable for Wnt/β-catenin signaling regulating neuronal layer fates in the developing brain.

Scleral Buckling Surgery in the Treatment of Retinal Detachment in Children – Own Results

Background:Retinal detachment it is a condition in which there is a disconnection between neuronal layer and choroidal layer of the retina, which is the pigment epithelium. The aim of our work was to evaluate the changes of visual acuity to the distance and to the nearest before and after surgery, and during the observation period, the assessment of anatomical length changes of the eyeball , the assessment of the intraocular pressure in the eyes after the procedure, the assessment of changes of the anatomical success to the retina using ultrasound in the projection (B).Methods:An 5- year retrospective study involved 73 children aged 5-17 years ( average age 11 years), who were operated due to retinal detachment. Patients were treated in the years 2013-2018 (June) in Pediatric Department of Ophthalmology in Katowice. The obtained results were subjected to statistical analysis using the STATISTICA 13.3 software program. We used the non- parametric Mann- Whitney U- test.Results:Among a group of operated children in 39% of retinal detachment due to head trauma or orbital area. About 29% children had average or high myopia due to the value-14.0 Dsph. 14% of children had retinal detachment due to retinopathy of prematurity, which had the vitrectomy at the end of the therapy. 18% of retinal detachment are caused by other factors-for example: infection of Toxocara or recurrent uveitis. The effect of application of the retina managed to get in 71% of eyes in the test group. 28% of eyes in this group require additional application of laser retinal as a complement to the residual retinal detachment. So obtained secondary effect of application of retinal eye surgery. While 29% of the eyes needed vitrectomy with vitreoproliferation and in the course of the retinopathy of prematurity.Conclusion:Retinal detachment is a very serious ophthalmologic condition that requires rapid surgical intervention.The latitudinal enlacement treatment is a treatment that does not disturb the proper development of the eyeball. The effect of the treatment is not predictable.The anatomical condition described as the retinal application does not always lead to a functional effect.

Brain Susceptibility to Methyl Donor Deficiency: From Fetal Programming to Aging Outcome in Rats

Deficiencies in methyl donors, folate, and vitamin B12 are known to lead to brain function defects. Fetal development is the most studied but data are also available for such an impact in elderly rats. To compare the functional consequences of nutritional deficiency in young versus adult rats, we monitored behavioral outcomes of cerebellum and hippocampus circuits in the offspring of deficient mother rats and in adult rats fed a deficient diet from 2 to 8 months-of-age. We present data showing that the main deleterious consequences are found in young ages compared to adult ones, in terms of movement coordination and learning abilities. Moreover, we obtained sex and age differences in the deleterious effects on these functions and on neuronal layer integrity in growing young rats, while deficient adults presented only slight functional alterations without tissue damage. Actually, the cerebellum and the hippocampus develop and maturate according to different time lap windows and we demonstrate that a switch to a normal diet can only rescue circuits that present a long permissive window of time, such as the cerebellum, whereas the hippocampus does not. Thus, we argue, as others have, for supplements or fortifications given over a longer time than the developmental period.
