Abstract:

Mitochondrial fission is mediated by the dynamin-related GTPase, Dnm1p, which assembles on the mitochondrial outer membrane into punctate structures associated with sites of membrane constriction and fission. We have identified additional nuclear genes required for mitochondrial fission, termed MDV (for mitochondrial division). MDV1 encodes a predicted soluble protein, containing a coiled-coil motif and seven COOH-terminal WD repeats. Genetic and two-hybrid analyses indicate that Mdv1p interacts with Dnm1p to mediate mitochondrial fission. In addition, Mdv1p colocalizes with Dnm1p in fission-m

Abstract:

Computer-based analysis systems are increasingly available for the clinical assessment of speech and voice functions. These systems have the potential to provide immediate quantitative information to assist clinical assessment and treatment. The Multi-Dimensional Voice Program (MDVP) is a computer program that can calculate as many as 33 acoustic parameters from a voice sample. The MDVP appears to have potential for rapid quantitative assessments of voice in both research and clinical applications. This report evaluates the robustness and reliability of MDVP for vocal analyses of 32 individual

Abstract:

Acoustic analysis of voice enables objective assessment of voice to diagnose changes in voice characteristics, and track the progress of therapy. In contrast to subjective assessment, objective measurements provide mathematical results referring to specific parameters and can be analyzed statistically. Changes in the voice of patients with partial deafness (PD) were not widely described in the literature, and recent studies referred to the voice parameters measured in this group of patients only using the multi-dimensional voice program (MDVP) by Kay Pentax.

The shedding profile of Marek's disease virus serotype 1 (MDV1, virulent), serotype 2 (MDV2, vaccinal) and herpesvirus of turkeys (HVT, vaccinal) in commercial broiler chickens was determined by measuring the daily rate of production of feather dander from chickens housed in isolators and by quantifying the viral load of each of these serotypes in the dander using quantitative real-time PCR (qPCR). MDV1 and HVT viruses were detectable in dander filtered from isolator exhaust air from day 7 and MDV2 from day 12 after infection and thereafter until the end of the experiment at 61 days of age of

HVT is very similar to MDV1 and MDV2 within the unique long (UL) and unique short (US) genomic regions, where homologous genes share a high degree of colinearity and their proteins share a high level of amino acid identity. Within the UL region, HVT contains 57 genes with homologues found in herpes simplex virus ty

Using machine learning algorithms, the presented research improves initial screening of Parkinson's disease on the examination of specific vocal characteristics. This ML technique applies by using a very large dataset from UC Irvine ML Repository with 197 distinct cases and 22 unique attributes. The accuracy of the KNN classifier turns out to be very accurate with an accuracy of 85%. Other than the KNN classifier, this study will l

Abstract:

In order to examine the differences in people suffering from depression (EG, N=18) compared to the healthy controls (CG1, N=24) and people with the diagnosed psychogenic voice disorder (CG2, N=9), nine acoustic features of voice were assessed among the total of 51 participants using the MDVP software programme ("Kay Elemetrics" Corp., model 4300). Nine acoustic parameters were analysed on the basis of the sustained phonation of the vowel /a/. The results revealed that the mean values of all acoustic parameters differed in the EG compared to both the CG1 and CG2 as follows: the parameters which

Objectives: The present study aims to compare acoustic voice parameters in patients with vocal cord nodules, polyps, and normal subjects. Methods: In this cross-sectional case-control study, the participants were selected by convenience sampling, including 30 patients with vocal polyps for the first group, 38 patients with vocal nodules for the second group, and 42 participants without voice pathologies as the control group. For each group, participants were examined by a speech and language pathologist (SLP) using an Endo-vision laryngoscope. Acoustic voice parameters were measured by MDVP so

Abstract:

Objectives: Speech-language pathologists (SLPs) are at high risk for voice disorders, and voice rest (VR) has commonly been used as a coping strategy. However, VR may lead to reduced income and service quality. Semi-occluded vocal tract exercises (SOVTEs), including voiced high-frequency oscillation (VHFO), provide immediate voice benefits without disrupting work routines. This study aimed to compare the efficacy of VHFO during rest periods between therapy sessions with VR in SLPs.Methods: Twenty-two 1st and 2nd grade SLPs without existing voice issues participated in a two-week crossover stud

Aim/Background: Individuals deprived of full hearing ability suffer from many problems in their social, professional, and personal lives. Prolonged hearing deprivation, particularly in children, results in many consequences including loss of control of one’s voice. Impaired hearing control of the voice leads to dysphonia of different degrees. The aim of this study was to analyse acoustic voice parameters in hearing-impaired, school-aged children (7–12 years) and the influence of treatment type on voice quality.

Abstract:

Vehicle scheduling problem consists in assigning vehicles to a set of time-tabled trips, wishing to minimize the objective cost function. Two aprroaches of the problem were studied: single-depot vehicle scheduling problem (SDVSP) and multiple-depot vehicle scheduling problem (MDVSP). There are known several methos of solving this problem based mainly on liniar programming, branch and bound, graph colouring thechniques. SDVSP is solvable in polynomial time, while MDSVP is NP hard. The main propose of this paper is to present a model based on Petri nets for the vehicle sceduling problem. We defi

WstępDysfonia spastyczna (inaczej: ogniskowa dystonia krtaniowa) to schorzenie neurologiczne wpływające na głos i mowę. Zaburzenie dotyczy aferentnej i eferentnej kontroli mięśni krtani podczas fonacji. Cechami charakterystycznymi są skrajnie parta i przerywana fonacja powstała na skutek skurczów mięśniowych w obrębie głośni. Wyróżnia się kilka postaci zaburzeń ze spektrum dysfonii spastycznej. Najczęściej patologia dotyczy przywodzicieli. Przegląd literatury wykazał, że dystonia krtaniowa jest niezwykle rzadko poruszanym tematem w polskojęzycznych publikacjach naukowych.
