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.

Long-wave infrared radiation reflected by compression stockings in the treatment of cellulite: a clinical double-blind, randomized and controlled study

SynopsisBackgroundCellulite refers to changes in skin relief on the thighs and buttocks of women, with a prevalence of 80-90%, causing dissatisfaction and search for treatment. Etiopathogenesis is multifactorial, as follows: herniation of the hypodermis towards the dermis, facilitated by perpendicular fibrous septa, changes in the dermal extracellular matrix, decreased adiponectin, genetic polymorphism, microcirculation alterations and inflammatory process. There are numerous therapeutic approaches, with little evidence of effectiveness. The long-wave infrared (LWIR) radiation interacts with water, improves microcirculation and stimulates metabolic processes. To date, the use of tissues with potential reflection of LWIR radiation has not been systematically investigated as adjuvant treatment for cellulite.ObjectiveTo investigate the efficacy and safety of the treatment of cellulite through the use of compression stockings made with thread reflecting LWIR radiation.Patients and methodsClinical study of therapeutic intervention, controlled and double-blind, including 30 women, aging from 25 to 40years, with cellulite of grades II and III on the thighs and buttocks who used compression stockings, pantyhose model, made with reflector thread of LWIR radiation, on only one randomized side. Women under other treatments for cellulite and with venous and/or blood insufficiencies were excluded. Evaluation of efficacy by clinical parameters, photographs, Dermatology Life Quality Index (DLQI), cutometry and high frequency ultrasonography and security by observation of adverse events and venous EcoDoppler recordings.ResultsDLQI scores showed significant reduction; the two-dimensional high-frequency ultrasonography showed an insignificant increase in dermal echogenicity as well as other efficacy parameters demonstrated no or slight improvement, with no differences between the sides exposed or not to LWIR; and there were no severe adverse events.ConclusionCompression stockings, with or without thread reflector of LWIR, showed slight effects in the appearance of cellulite, but the treatment determined a positive impact on women quality of life.

Notes on the feeding behaviour and swimming pattern of Manta alfredi (Chondrichthyes, Mobulidae) in the Red Sea

The feeding behaviour and the swimming pattern of the reef manta (Manta alfredi) are described based on video recordings conducted in Sudan, Red Sea, Indian Ocean, during June 2001. Three circular swimming patterns are described: horizontal circle pattern, inclined circle pattern and double circle pattern, related to feedings on zooplankton distributed in the water column. The observation of circle-like swimming patterns for reef manta rays in shallow waters expands our knowledge about M. alfredi and suggests that the distribution and abundance of zooplankton influence the occurrence and group size of this species in the studied area, as reported from other localities for Manta species.

Relação entre acurácia na repetição de palavras e conhecimento lexical em crianças

There is in the literature a divergent description between lexical knowledge and word production accuracy. The aims of this study were: (a) to investigate the influence (effect) of the word lexical knowledge over production accuracy; (b) in case there is, to characterize acoustically this interference. Eight children (5-6 years old) with typical development language participated of this study. The methodological procedure consisted of: (a) survey of the children lexical knowledge concerning to IAFAC’s words; (b) recordings of the IAFAC’s words; (c) identifi cation and characterization of the linguistic cues, by acoustic analysis, in the IAFAC’s word production in function of the different knowledge degrees. Our results suggest a negative correlation (r=-0,13, p=0,000) between lexical knowledge and presence of the linguistics cues in word’s production. However, the linguistics cues refer to hesitative cues instead of phonological errors. Implications of these results for clinical practicing are discussed.

Uso de sistemas de comunicação suplementar e alternativa na Educação Infantil: percepção do professor

Augmentative and Alternative Communication Resources have proven to be helpful in the insertion of students with disabilities and complex communication needs into a variety of pedagogical activities and expand the skills and competencies of the teacher in the teaching-learning. The objective of this research was to identify the perception of teachers regarding the use of augmentative and alternative communication during an intervention program in Preschool. Participants were a special class of Preschool students with disabilities and severe communication complexity, along with their teacher and the researcher. For the development of this research, a Alternative Communication Program was applied. The teacher was provided with systematic guidance concerning language and communication. In a collaborative process, three children’s songs were selected according to the teacher’s pedagogical planning and adapted resources through Augmentative and Alternative Communication Systems. During the intervention program, assisted evaluations also took place immediately after the activities with the music. The data were collected in audio recordings. For data analysis, content analysis was carried out resulting in the outlining of themes and subthemes. Results indicated that the teacher identified that Augmentative and Alternative Communication Systems can to facilitate expression abilities of students with disabilities; that Augmentative and Alternative Communication Systems can be used by children in Preschool; and that resources adapted through augmentative and alternative communication systems should be in accordance with the specificities of students.

Pausas na interpretação teatral: delimitação de constituintes prosódicos

We intend to observe the function of a linguistic resource – the pause – in theatrical interpretation. Connected to the field of speech therapy, we search for theoretical support in the Linguistics field, mainly in prosodic phonology – specifically, we highlight intonational phrase and phonological utterance, prosodic constituents –, proposing a dialogue between these fields, regarding the work with actors. In speech therapy literature, the work with actors focuses, centrally, in organic issues involved in the vocal process, such as “misuse” or “voice abuse”. To a smaller extent, we find, in this literature, researches that emphasize issues regarding interpretation and expressive resources, besides a few emphasizing the importance of linguistic resources in interpretation. Differently, in linguistics literature, the pause is approached, to a larger extent, from the phonetic perspective, related to several language levels. In this research, we analyzed audio recordings of four actors from a same theatrical group, acting the theatrical text Brutas flores, focused on these aims: (1) detect the place where pauses happen in the interpretation of a single text by four actors; (2) survey physical characteristics of length of these pauses; (3) check to what extent the length of a pause is related to the place where it happens, regarding the prosodic limits of intonational phrases (I) and phonological utterance (U). We could observe that, although the interpretation is characterized by the subjectivity of the actor, the interpretation is constructed based in the possibilities offered by the prosodic organization of the text itself, being more or less flexible.We were also able to confirm, by considering the length of VVs units containing pauses, the prosodic hierarchy proposed by Nespor & Vogel, once the length of these units in U's limits was significantly higher than the length in I's limits. Thus, our results reinforce the premise that a linguistic structure overlaps the subjectivity of the actor, i. e., the premise that the strength of linguistic structure organization acts on the possible individual operation/style.

Comparação entre medidas acústicas de vogais em provas de repetição e conversa espontânea

The aim of this study is to compare acoustic measures (frequency, duration and intensity) of the vowels /i, a, u/ in repetition and spontaneous tasks. Recordings of words produced by ten children with typical language development in both controlled and spontaneous tasks were selected from a database. The vowels were selected and edited into individual files in the software PRAAT. Acoustic measures related to formant frequency (F1 and F2), intensity and duration of vowels in both contexts were extracted. The values obtained were compared by means of T Tests. In general, the acoustic analysis showed no differences between the two contexts of speech production. The few differences found can be explained by the presence of focus and/or hesitation phenomena during the speech productions. It is possible to use data from spontaneous context to analyze the vowels acoustically, provided that both the phonetic context of the vowel occurrence and the syllable stress of the vocalic segment are considered.

Jogo de papéis e linguagem: diálogos possíveis entre Vigotski e Bakhtin

In this paper we present ongoing research in which we approach the regulatory role of language in role play in children aged six and seven. In research, we seek an understanding of the relationship between language, ownership and complexity of the children's game. The hypothesis guiding the research is that the dialogical relations between children and adults and among children, while playing, contribute to children's learning game. Procedures are being used interpretive ethnographic research that focuses on the human meaning of social relations, waged by the subjects in a particular historical context and its elucidation and exposition by one researcher. This approach allows closer studies of Vygotsky and Bakhtin scholars of language that emphasize the regulatory role of language in human relationships and value the dialogic exchange between researcher and researched; active subjects of the research process. The data were produced by means of observation and interview, in a field diary records, photographs and audio recordings. They are being screened in thematic groups and analyzed using interpretative narration. The participants were two teachers and two classes of the first year of an Elementary school (EMEF) School of Municipal Elementary School Crane, State of Sao Paulo, totaling 45 subjects. Bearing in mind the above assumptions, are presented and analyzed data that allow to anticipate some results.
