Metodos de Processamento de Imagens para Determinação de Dano em DNA

Patente de invenção de métodos para processamento de imagens obtidas a partir de amostras preparadas 'cbnforme protocolo para reajízação de teste do cometa, particularmente corado pela prata. Este teste é amplamente utilizado para avaliação de genotoxicidade de substâncias. Há sistemas automatizados que analisam cometas corados por substâncias fluorescentes. A coloração de prata é uma técnica pouco difundida pela falta de tecnologia de análise digital automatizada e tem desempenho semelhante às técnicas com fluorescência, porém, é de baixo custo, rápida execução, não depende de microscópios de fluorescéncia e não utiliza produtos mutagênicos em seu protocolo.

A sedação sobre os potenciais evocados auditivos em cães

Brainstem auditory evoked potential (BAEP) reflects the electrical activity along the auditory pathway, from the cochlea to the brainstem, and contributes for the diagnosis of deafness in dogs. BAEP recording may require chemical restraint in some cases, so this study was designed to analyze the impact of sedation with morphine and acepromazine on the BAEP recordings of 16 dogs with normal hearing. BAEPs were recorded before and during sedation with a combination of morphine (0.5mgkg(-1)) and acepromazine (0.05mgkg(-1)) given intramuscularly. The protocol employed allowed safe and effective animal restraint. Sedation increased the latency of waves II and III and intervals I-III and I-V but did not interfere with wave identification. and showed to be safe in the dogs tested. Based on the current literature this is the first study which assessed the impact of sedation on BAEPs in dogs in Brazil.

Relação entre potenciais evocados auditivos de média latência e distúrbio de processamento auditivo: estudo de casos

The Auditory Evoked Middle Latency Response is one of the most promising objective tests in audiology and in revealing brain dysfunction and neuro-audiologic findings. The main advantages of its clinical use are precision and objectivity in evaluating children. This study aimed to analyze the auditory evoked middle latency response in two patients with auditory processing disorder and relate objective and behavioral measures. This case study was conducted in 2 patients (P1 = 12 years, female, P2 = 17 years old, male), both with the absence of sensory abnormalities, neurological and neuropsychiatric disorders. Both were submitted to anamnesis, inspection of the external ear canal, hearing test and evaluation of Auditory Evoked Middle latency Response. There was a significant association between behavioral test and objectives results. In the interview, there were complaints about the difficulty in listening in a noisy environment, sound localization, inattention, and phonological changes in writing and speaking, as confirmed by evaluation of auditory processing and Auditory Evoked Middle Latency Response. Changes were observed in the right decoding process hearing in both cases on the behavioral assessment of auditory processing; auditory evoked potential test middle latency shows that the right contralateral via response was deficient, confirming the difficulties of the patients in the assignment of meaning in acoustic information in a competitive sound condition at right, in both cases. In these cases it was shown the association between the results, but there is a need for further studies with larger sample population to confirm the data.

Potenciais evocados auditivos de longa latência em escolares com transtornos específicos de aprendizagem

Purpose: To study the components of long latency auditory evoked potentials and to compare data from these measures in students with and without learning disabilities. Method: Thirty students, 15 with learning disorder (study group) and 15 typical without learning problems (control group), of both genders, aged 7-14 years, mean age 10 years. They underwent clinical assessment in a clinic belonging to a public university in the state of São Paulo. Following, audiological assessment was performed to determine normal peripheral auditory system and electrophysiological assessment by examining the long latency auditory evoked response. Result: The results showed that there are functional differences between the groups. Increased latency components of long latency auditory evoked potential was observed in the study group compared to the control group. Longer latency values of these components were observed in the left ear when stimulated in the study group. Conclusion: This study contributed to better understanding of the auditory pathway functioning in children with learning disorders and can be a reference for other clinical and experimental studies and thus improve the definition of diagnostic criteria in this population.

O ensino da matemática aos deficientes auditivos

The theme of this research is mathematics education for the deaf. It is hoped that this work will enable more thorough understanding of the subject matter, since, to be inclusion of people with hearing disabilities in society is necessary to establish measures ranging acceptance and family participation to break prejudices and demystification related learning ability of these individuals. This research also aims to provide grants for teaching mathematics to deaf , so that the teacher can build a current pedagogical practice that will not only meet their expectations as a teacher , but above that encourages the development of skills essential to the competence of the student with special educational needs . An educational practice based in the communication and interaction between teacher and students, with the intention of providing an effective meaning of mathematical knowledge, you can add new possibilities in an educational context marked by scarcity of communicative opportunities

Sintomas auditivos e desordens temporomandibulares

Introduction: A variety of hypotheses have been proposed to explain the association between temporomandibular disorders and hearing symptoms, including the many anatomical and/or neurological ways, as of a muscle or joint dysfunction, can cause such symptoms. Objective: The purpose of this study is to discuss, through a systematic review of literature, the interrelation between hearing symptoms and temporomandibular disorders. Material and Methods: We consulted the Medline/PubMed, ISI and Scielo in the period 1918 to 2008. The terms related to the research were: “temporomandibular disorders”, “signs and symptoms of temporomandibular disorders”, “otologic symptoms” and “aural symptoms”, where 19 papers were included using the pre-selected criteria for the manufacture of a meta-analysis. Results: According to the findings, the hearing symptoms most often associated with temporomandibular disorders were otalgia and tinnitus, followed by vertigo and hearing loss, respectively. Conclusions: It’s clear the correlation between hearing symptoms and temporomandibular disorders, however there is a need clinical and scientific research more complex to prove the specific cause-effect relationships between them.

Fenômenos alucinatórios auditivos em pacientes com zumbido: relações afetivas e aspectos depressivos

INTRODUÇÃO: Nos últimos anos, identificamos um número crescente de pacientes com zumbido que também referiam percepções repetidas de sons complexos, como músicas e vozes. Tais fenômenos alucinatórios nos instigaram a estudar suas possíveis relações com o psiquismo destes pacientes. OBJETIVOS: avaliar se os fenômenos alucinatórios dos pacientes com zumbido têm relação com psicose e/ou depressão, além de esclarecer seu conteúdo e função no psiquismo. MÉTODO: Dez sujeitos (8 mulheres, idade média de 65,7 anos), selecionados por otorrinolaringologistas, foram avaliados pela mesma psicóloga por meio de entrevista semi-dirigida, Escala para Depressão de Hamilton e entrevistas psicanalíticas. RESULTADOS: Nenhum dos pacientes apresentou relação dos fenômenos auditivos com psicose, mas sim com aspectos depressivos. O discurso dos pacientes evidenciou que os fenômenos apresentam funções inconscientes na vida afetiva de cada um. A forte tendência à rememoração/repetição de fatos/situações desagradáveis foi marcante em todos os casos, tendendo a exacerbar o incômodo com o zumbido, com os fenômenos alucinatórios e a piorar aspectos depressivos. CONCLUSÕES: Há uma importante relação entre zumbido, fenômenos alucinatórios e depressão, sustentada na rememoração persistente de fatos/situações que causam sofrimentos psíquicos. O conhecimento destes achados representa mais um passo em direção à necessidade de particularizar o tratamento deste subgrupo de pacientes com zumbido, envolvendo equipe multidisciplinar. Prospectivo.
