ANALYZING ULTRASONOGRAPHY AS A NON-INVASIVE TECHNIQUE FOR ESTIMATING BODY CONDITION IN GREEN (CHELONIA MYDAS) AND LOGGERHEAD (CARETTA CARETTA) SEA TURTLES

Unknown Date (has links)
In sea turtles, body condition can be evaluated through subjective body condition scoring (BCS), calculating body condition index (BCI), and clinical blood parameters. The goal of this study was to analyze ultrasonography of subcutaneous fat depth as a method to estimate body condition in 10 green and 8 loggerhead sea turtle carcasses using two types of portable ultrasound technologies, the Ibex Evo® and the Renco Lean-Meater®. Despite the general lack of significant correlations between ultrasound-assisted, gross, and histological measurements, the dorsal shoulder and lateral neck were determined to provide the most consistent images of subcutaneous fat. Florida live-captured green turtles were sampled and ultrasound-assisted fat depth measurements were taken at the dorsal shoulder region; however, there were no significant correlations found between fat depth and BCI or blood analytes (PCV, total protein). BCI reference quartiles were created using associations between BCI and BCS to help provide biological context to BCI data and allow for rapid categorization of sea turtle body condition. / Includes bibliography. / Thesis (MS)--Florida Atlantic University, 2021. / FAU Electronic Theses and Dissertations Collection

Estudo comparativo entre clínica, eletroneurografia e ultrassonografia do nervo ulnar e pacientes com hanseníase multibacilar /

Grassi, Graziela Ferrarezi da Silva. January 2015 (has links)
Orientador: Joel Carlos Lastória / Banca: José Antonio Garbino / Banca: Jorge de Almeida / Resumo: Foi realizado estudo transversal, descritivo e observacional de 38 nervos ulnares de pacientes com hanseníase multibacilar, com idades entre 20 e 59 anos, com diagnóstico realizado na disciplina de dermatologia da Faculdade de Medicina de Botucatu (FMB-UNESP). Estes pacientes foram submetidos à palpação, exames de eletroneurografia e ultrassonografia dos nervos ulnares direito e esquerdo com o objetivo de estudar o comprometimento do nervo pela doença e comparar os resultados dos exames. Dos nervos estudados, nove (23,68%) não apresentaram nenhuma alteração nos resultados dos exames. Os que apresentaram alteração em um ou mais dos exames realizados, somaram 29 (76,32%). Os resultados foram comparados, e os que apresentaram alterações de normalidade em dois ou mais, foram denominados compatíveis. Houve compatibilidade de 20,68% entre clínica, eletroneurografia e ultrassonografia. Observou-se que esse fato ocorreu quando o exame ultrassonográfico mostrou valores próximos do dobro da normalidade. Não houve significância estatística entre os resultados apresentados; no entanto, deve-se considerar a correspondência entre os exames clínico, eletroneurográficos e ultrassonográficos / Abstract: A cross-sectional, descriptive, observational study of 38 ulnar nerves of multibacillary patients, aged 20 to 59 years, with diagnosis made in Dermatology course of the Faculty of Medicine of Botucatu (FMB-UNESP). These patients underwent palpation, ultrasound exams and electroneurography ulnar nerve left and right in order to study the nerve disease involvement and compare the test results. The nerves studied, nine (23.68%) showed no change in the results of the examinations. Those who had alterations in one or more of the tests performed, totaled 29 (76.32%). The results were compared, and those with normal changes in two or more, were called compatible. There was 20.68% compatibility between clinical, electroneurography and ultrasound. It was observed that this actually occurred when the ultrasound examination showed values close to double the normal. There was no statistical significance between the results presented; however, one must consider the correlation between the clinical, electroneurographic and ultrasonography / Mestre
