| 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. |

| 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... |

| 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,... |

| ABSTRACT This study was intended to evaluate body size structure and growth parameters of crossbred heifers fed at four nutritional levels to achieve puberty earlier. Animals were classified depending on their level of crossing between Nelore and Hereford and subjected to four nutritional levels (kg day−1) as follows: 0.5 (light; n = 32), 0.75 (medium; n = 32), 1.00 (high; n = 29), and 1.25 (very high; n = 27). Heifers at puberty and at weaning were individually classified for growth parameters. The fat thickness and longissimus muscle area throughout the experimental period were determined by ultrasonography. The height, heart girth, frame, and weight:height ratio were variables used to evaluate body traits. Univariate analysis of variance using the GLIM... |

| ABSTRACT The objective of this study was to evaluate the production performance and carcass traits of feedlot steers fed a high-energy diet supplemented with doses of an enzyme complex (0, 2.5, 5.0, and, 7.5 g animal−1 day−1). Thirty-two ½ Angus ½ Nellore crossbred steers at an average age of 12 months and an average initial weight of 422 kg, were kept in a feedlot for 77 days. The roughage-free diet was composed of a mixture of whole corn grain and a protein-mineral-vitamin mix at a constant ratio of 85:15, on a dry matter basis. A completely randomized block design was adopted, consisting of four treatments and four replicates, in which each replicate was represented by a stall with two animals. Each gram of product added to the diet led to a decrease of... |

| Cerebrovascular accidents (CVA) are important causes of neurological clinical signs in dogs. The objective of this work was to describe concurrent diseases and ultrasonographic features in dogs with CVA confirmed through postmortem evaluation. All medical records of transcranial Doppler ultrasonography (TCDUS) examinations performed in 512 dogs between 2007 and 2009 were reviewed, searching for history and clinical diagnosis, as well as sonographic and histological results. Forty-two dogs were selected, showing acute onset of clinical signs with no progressive focal cerebral dysfunction and diagnosis of cerebrovascular disease confirmed at necropsy. Concurrent diseases and conditions were: cerebral amyloid microangiopathy (33%), endocrinopathies (31%),... |

| The left displacement of the large colon, a condition that commonly occurs in horses, has two clinical manifestations. Different treatments including medical treatment, rolling the horse under general anesthesia or surgical correction have been recommended. The diagnosis can often be made by rectal examination and confirmed by percutaneous ultrasonography. During the period between 2004 and 2009, 11 horses were treated for left displacement of the large colon by rolling the horses under general anesthesia, using a slightly different technique than the ones previously described. The clinical case selection was based on rectal palpation confirmed with ultrasonogram. Nine animals were successfully treated and two had to be submitted to surgery after three... |

| 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. |

| The effect of substitution of equine chorionic gonadotropin (eCG) by follicle stimulating hormone (FSH) in synchronization protocols of ovulation in dairy goats was evaluated. Twelve goats received intravaginal sponges impregnated with 60mg of medroxyprogesterone acetate (MAP) for 10 days. The sponges were removed and the animals were distributed into two groups (G): G1 (n=6) treated with 0.5mL of a synthetic analogue of PGF2 α and 100 IU of eCG for each 10kg weight, intramuscular injection (IM); and G2 (n=6) treated with 0.5mL of a synthetic analogue of PGF2α and 20mg of FSH (IM). All animals were monitored for estrus detection with aid of a ruffian after sponge removal. The ovarian dynamics were analyzed by ultrasound, since six hours after sponge... |

| Objetivou-se descrever os achados clínicos e ultrassonográficos de uma cabra leiteira apresentando mastite gangrenosa. Com a ultrassonografia convencional, observaram-se alterações consistentes com o avanço do quadro clínico, como alterações na ecogenicidade do leite e parênquima mamário. A ultrassonografia Doppler revelou aumento da velocidade de pico sistólico nos três momentos estudados, passando de 15 para 17 e 29cm/s. Houve redução, também, dos valores do índice de resistência, de 0,71 para 0,61 e 0,43. O índice de pulsatividade sofreu redução entre o segundo e o terceiro dia de observação, passando de 0,98 para 0,71. Foi possível estabelecer relação direta entre os achados ultrassonográficos e a gravidade da doença. A ultrassonografia convencional e... |

| A- and B-modes ultrasonographic changes in the thickness of various structures of the eyeball in male and female English Cocker Spaniel dogs with and without nondiabetic cataracts were evaluated. Sixteen dogs with cataracts (32 eyes) and seven normal dogs (14 eyes) older than eight years were selected. A- and B-modes ultrasonography was performed with a 10MHz transducer. Data was statistically evaluated by one way ANOVA. Mean and standard deviations of various ocular structures for dogs with and without cataracts were, respectively, anterior chamber: 3.041±0.828mm, 3.373±1.040mm; lens: 6.817±1.117mm, 7.062±0.477mm; vitreous: 10.056±0.754mm, 9.523±0.705mm; and axial length: 19.909±1.103mm, 19.958±1.050mm. Ocular measurements between right and left eyes,... |
