The mechanisms involved in the emergence of virulent mammalian viruses were investigated in the adult immunodeficient SCID mouse infected by the attenuated prototype strain of the parvovirus Minute Virus of Mice (MVMp). Cloned MVMp intravenously inoculated in mice consistently evolved during weeks of subclinical infection to variants showing altered plaque phenotypes. All the isolated large-pla...

a palatal defect may result from surgical resection, and its consequences could include difficulty in speech and nasal regurgitation of food and liquids. an obturator combined to speech aid prosthesis can improve nasal emission during speech,  and  assist  in  preventing  nasal  regurgitation  of  food.  this  article presents a clinical report of the reconstruction of palatopharyngeal function...

Introduction: Speech intelligibility, the ability to be understood verbally by listeners, is the gold standard for assessing the effectiveness of cochlear implantation. Thus, the goal of this study was to compare the speech intelligibility between normal-hearing and cochlear-implanted children using the Persian intelligibility test.   Materials and Methods: Twenty-six cochlear-implanted childre...

A leucemia felina (FeLV) é causada por um vírus da família Retroviridae do gênero Gammaretrovírus, podendo acometer ocasionalmente os felinos selvagens e também domésticos. Possui quatro subgrupos: FeLV-A, B, C T. Sua patogenia complexa depende de diversos fatores, mas o principal sistema imune animal. Por ser uma doença imunossupressora, felino fica susceptível a inúmeras doenças e, isso, sint...

The speech enhancement techniques are often employed to improve the quality and intelligibility of the noisy speech signals. This paper discusses a novel technique for speech enhancement which is based on Singular Value Decomposition. This implementation utilizes a Genetic Algorithm based optimization method for reducing the effects of environmental noises from the singular vectors as well as t...

BACKGROUND Noninvasive ventilation (NIV) has been recognized as an effective strategy in preventing endotracheal intubation in subjects with acute respiratory failure (ARF). Some interface-related complications have also been recognized, such as skin breakdown (SB). The aim of this study was to determine the frequency of SB and identify potential treatment-related risk factors for its developme...

The aim of this study was to evaluate the effects of repeated oronasal administration of lipopolysaccharide (LPS) on milk composition and the overall productive performance of dairy cows. One hundred pregnant Holstein dairy cows were randomly assigned to two treatment groups (n = 50). 30 cows out of 100 were selected for intensive sampling (n = 15) starting at 28 d before parturition. Cows were...
