Autores: Murata, Koichiro; Sugisaki, Norihide; Miyamoto, Naokazu; Wakahara, Taku; Kanehisa, Hiroaki; Kawakami, Yasuo; Fukunaga, Tetsuo; 村田, 浩一郎.
This study aimed to determine the elastic properties of human triceps brachii (TB) tendon. The elongation of the TB tendon was directly measured in 9 healthy males using ultrasonography during ramp isometric elbow-extension up to the maximal voluntary contraction (MVC). The slope of the regression line for the relationship between the estimated muscle force and the angular rotation-corrected tendon elongation above 50%MVC was defined as stiffness. The stiffness of the TB tendon, 83±22 N/mm, was comparable with that of the gastrocnemius tendon reported previously. The relationship between the stiffness and the tendon length (TL) showed a negatively significant correlation, suggesting that the stiffness of TB tendon is influenced by its dimensions.

The applications of timed artificial insemination and timed embryo transfer in reproductive management of dairy cattle
Provedor de dados: 96
Autores: Ambrose,Divakar Justus; Colazo,Marcos Germán; Kastelic,John Patrick.
Fertility of dairy cattle is generally decreasing. Overall estrus detection efficiency in lactating dairy cattle is low, as expression of estrus is often compromised. Consequently, undetected estrus, low AI-submission rates, and long inter-breeding intervals are the main contributors to poor reproductive efficiency. Although failure to become pregnant is the most common reason for culling dairy cattle, pregnancy rates could be improved by increasing the AI-submission rate through increased estrus detection efficiency, timed insemination (Timed-AI), or timed embryo transfer (Timed-ET). In these protocols, ovarian follicular development and luteolysis are controlled, culminating in synchronous ovulation in most cows. There are several modifications to...

Biometry and ultrasound evaluation of testicles and accessory glands in Santa Ines rams
Provedor de dados: 96
Autores: Ribeiro,Mariana da Silva; Quirino,Celia Raquel; Bartholazzi Junior,Aylton; Pacheco,Aline.
ABSTRACT This work aimed to investigate the relationship between echogenicity, testicular biometry, and accessory gland biometry and evaluate the echogenicity pattern of these structures in Santa Ines rams. Fifty-four healthy Santa Ines sheep were classified into three age groups: group 1 - 3 to 5 months (pre-pubertal); group 2 - 7 to 11 months (pubertal); and group 3 - 13 to 28 months (sexually mature). The averages of testicular biometry and bulbourethral gland biometry were different among age groups. The testicular parenchyma was homogeneous with low echogenicity (pre-pubertal group) and medium echogenicity (pubertal and sexually mature groups), suggesting that testicular echogenicity can be a helpful tool to identify the start of puberty. The...

Autores: Arashiro,Eduardo Kenji Nunes; Viana,João Henrique Moreira; Fonseca,Jeferson Ferreira da; Camargo,Luiz Sérgio de Almeida; Fernandes,Carlos Antônio de Carvalho; Brandão,Felipe Zandonadi.
The aim of this study was to establish the morphologic and endocrine characteristics of luteal dynamics in goats. It was used Toggenburg female goats that showed natural estrus in a 48-hour interval. After estrus, ultrasonographic evaluations of the ovaries were daily performed during 21 days using a portable device (5MHz probe). Blood sample was collected for plasma progresterone (P4) determination. Corpora lutea were detected for the first time on day 5 and progressively increased in size until D9 (1.26 ± 0.08 cm²), with no variation on subsequent days. In females with one ovulation, the first visualization of the corpora lutea was earlier than in those with multiple ovulation (4.54 ± 0.18 vs 5.74 ± 0.25 days). At the moment of the first visualization,...

Pelvic osteosarcoma ressection in a bitch: case report
Provedor de dados: 45
Autores: Rodrigues,B.A.; Faraco,C.; Oliveira,R.; Cheuiche,S.; Teixeira,F.S.; Kirst,C.; Faraon,A.; Sousa,E.M.
An osteosarcoma involving the pelvis was diagnosed in a 9-year-old neutered Labrador bitch. The clinical signs manifested by the patient before surgical removal of the tumor included urinary difficulty, dyschezia, and inconstant non-weight-bearing on the hindlimbs. These signs were linked to the localization of the tumor, which was identified as a firm and painful mass of the size of an orange in the caudal abdomen. The favorable short term clinical results after surgery and carboplatin chemotherapy showed that the association of these approaches can be employed to manage discomfort inflicted by tumor and, therefore improve the quality of life of patient of bone cancer.

Sonographic assessment of vessel invasion by cervical masses in dogs
Provedor de dados: 45
Autores: Carvalho,C.F.; Ruivo,C.N.; Simão,C.M.; Viani,F.C.
Tumor invasion of the vessels displays both therapeutic and prognostic implications and represents a challenge for head and neck surgeons. Although previous research has shown that ultrasound can detect such invasions, accurate sonographic parameters to do so have not yet been established. We sought to determine sonographic criteria which are able to characterize these invasions. A high-resolution transducer was used to perform ultrasound examinations of 15 patients selected from a group with inconclusive radiography and computed tomography diagnosis. We found that encasement of the vessel, tumor immobility or fixation in the vessel wall, and narrowing and/or deformity of the lumen were the best criteria. Indeed, when loss of hyperechoic interface of the...

In modern society the work and athletic performance of horses has led to a very important animal production sector in which Brazil possesses the third largest horse stock. Among all equine lesions described, metacarpophalangeal (fetlock) joint lesions are considered one of the main causes of lameness. Consequently, there is a need to improve the understanding and diagnosis of these injuries. The most efficient imaging diagnostic methods for the fetlock region are computed tomography, radiography and ultrasound. Imaging studies of the anatomical structures involving this joint are extremely important to obtain a more precise diagnose. The present study was performed in order to evaluate the capacity of different imaging diagnostic modalities to detect a...

OBJECTIVES: Progression of hepatic fibrosis is accelerated in patients co-infected with human immunodeficiency virus and hepatitis C virus compared to hepatitis C virus mono-infected patients. This study aimed to compare ultrasound features and selected clinical and biochemical variables between patients with human immunodeficiency virus/hepatitis C virus co-infection (n = 16) versus hepatitis C virus mono-infection (n = 16). METHODS: Each patient underwent abdominal ultrasound, and a specific evaluation was performed in order to detect findings consistent with chronic liver disease. Characterization of spleen size, liver structural pattern, diameter of the portal, spleen, and mesenteric veins was based on classical ultrasound parameters. Propensity score...

Provedor de dados: 56
Autores: Souza,E.V.; Torloni,M.R.; Atallah,A.N.; dos Santos,G.M.S.; Kulay Jr,L.; Sass,N.
Preeclampsia is an important cause of maternal and perinatal morbidity and mortality. Previous studies have tested calcium supplementation and aspirin separately to reduce the incidence of preeclampsia but not the effects of combined supplementation. The objective of this study was to investigate the effectiveness of aspirin combined with calcium supplementation to prevent preeclampsia in women with chronic hypertension. A double-blind, placebo-controlled randomized clinical trial was carried out at the antenatal clinic of a large university hospital in São Paulo, SP, Brazil. A total of 49 women with chronic hypertension and abnormal uterine artery Doppler at 20-27 weeks gestation were randomly assigned to receive placebo (N = 26) or 100 mg aspirin plus 2...

Ultrasonographic determination of goiter prevalence in southern Brazilian schoolchildren
Provedor de dados: 56
Autores: Lisbôa,H.R.K.; Gross,J.L.
The aim of the present study was to estimate the prevalence of goiter in schoolchildren in a formerly iodine-deficient region in southern Brazil by assessing the relationship between body surface area (m²) and thyroid volume (ml) measured by ultrasonography. A population-based sample of 1,094 randomly selected schoolchildren (6 to 14 years; 556 boys and 538 girls) underwent clinical evaluation. A total of 119 (10.9%) children were diagnosed with goiter upon clinical examination according to WHO criteria (grade Ia: 65, grade Ib: 24, grade II: 29, grade III: 1). Of these, 85 underwent ultrasonography. In order to ascertain the absence of goiter in the 975 schoolchildren with a negative result upon clinical examination, one of ten children was randomly...

Autores: Amaral,Andréia Vitor Couto do; Silva,Germana Alegro da; Costa,Ana Paula Araújo; Coelho,Cássia Maria Molinaro; Renzo,Roberta; Laus,José Luiz.
The effects of sildenafil on retrobulbar and retinal circulation were studied in 18 adult male, albino, homozygous rabbits, of the New Zealand White breed, randomly divided into 3 groups of 6 animals, for drug treatment at a dose of 3.5mg kg-1 every 24 hours, for 7, 15 and 30 days. Nine animals used for control were treated with saline solution at 0.9%. It was evaluated intraocular pressure (IOP), mean arterial pressure (MAP), ocular perfusion pressure (PPO), B-mode ultrasonography and fluorescein angiography before and at the end of treatments. A slight decrease in results of IOP, MAP and PPO after treatment with sildenafil was evident, however, there was no statistical significance. It was observed significant increased diameter of the ophthalmic artery...

ABSTRACT: The carpus is a complex articulation, which is often involved in injuries in equine athletes. The objective of this study was to suggest a didactic approach for ultrasonography training for the examination of the carpal joint in horses. Ultrasonograhy examination was performed in a healthy 14-year-old horse. The images were compared with those of a dissected anatomic specimen of the carpal region of a senior horse and with those reported in the literature. Identifiable structures were as follows: (dorsal) tendon of the muscle extensor carpi radialis, tendon of the muscle extensor carpi obliquus, tendon of the muscle commom digital extensor, dorsal synovial outpouchings, joint capsule and fat cushion, (lateral) tendon of the muscle lateral digital...

Dopplervelocimetric evaluation of portal vein as a diagnostic tool for portosystemic shunt diagnosis in dogs
Provedor de dados: 65
Autores: Carvalho,Cibele Figueira; Cerri,Giovanni Guido; Chammas,Maria Cristina.
The objective of this research was to verify if the study of portal hemodynamic parameters through duplex Doppler ultrasonography (DUS) is able to help to detect portosystemic shunt (PSS) and the shunted vessel origin. It was detected PSS in 20 dogs by abdominal DUS and confirmed at surgery or necropsy from March of 2004 until March 2007. Main ultrasonographic findings were: identification of a tortuous vessel shunting portal flow being: portocaval shunt (16/20 or 80%), esplenocaval shunt (2/20 or 10%), gastrocaval shunt (1/20 or 5%), portoazigo shunt (1/20 or 5%); 2) elevated portal flow velocity before shunt (17/20 or 81%), 3) lower portal flow velocity after shunt (17/20 or 81%), 4) turbulence in the caudal vena cava (10/20 or 47,5%) and 5) reduced...
