| ABSTRACT To describe the ARFI elastography in the evaluation of the adrenal glands in adult dogs, to evaluate the stiffness of adrenal parenchyma and to determine the qualitative and quantitative standards of the ARFI technique, which have not yet been described in veterinary medicine. Sixty adrenal glands from thirty healthy adult dogs were evaluated by B-mode and qualitative and quantitative ARFI elastography to assess the stiffness of healthy parenchyma and to determine the quality and quantity (shear velocity) standards of ARFI technique in body, cranial and caudal adrenal poles. Findings of ultrasonography evaluations were normal. Qualitative elastography showed that adrenal glands were not deformable and presented homogeneous middle-gray areas. The... |

| ABSTRACT Eyes from brachycephalic dogs were studied by acoustic radiation force impulse (ARFI) elastography to establish quantitative and qualitative reference values related to the shape and rigidity of some ocular structures. Eighty-four eyes from 42 adult brachycephalic dogs were included in this study. Animals were subjected to physical, laboratory, and ophthalmic examinations. Following confirmation of good health, the dogs were subjected to ultrasonography and ARFI elastography, emphasizing the optic nerve, ciliary body, and lens. On qualitative elastography, homogeneous characteristics were observed on the ciliary body and optic nerve. Aqueous and vitreous humors were visualized as mosaic-like images. Quantitative elastography showed the mean optic... |

| We investigated whether liver injury by dual exposure to ethanol and carbon tetrachloride (EtOH + CCl4) for 15 weeks would persist after hepatotoxic agents were removed (EtOH + CCl4/8wR). After 15 weeks of hepatic injury with ethanol (5.5%, m/v) and carbon tetrachloride (0.05, mL/kg, ip), 5 of 11 female Wistar rats were sacrificed. The other 6 rats were maintained for an additional 8 weeks without hepatotoxic agents. Ultrasonography showed increased liver echogenicity and dilation of portal vein caliber in both groups (EtOH + CCl4: 0.22 ± 0.01 cm, P < 0.001; EtOH + CCl4/8wR: 0.21 ± 0.02 cm, P < 0.01) vs control (0.16 ± 0.02 cm). Histopathology showed regenerative nodules in both experimental groups. Histomorphometry revealed increased fibrosis... |

| ABSTRACT The study has been conducted over a period of 4 years, on a total number of 133 dogs, all of those expressing gastrointestinal disorders. Ultrasound and endoscopic examinations were performed in all dogs in order to assess any significant correlations between ultrasonographic and endoscopic findings. The results confirm a significant correlation between the presence of diarrhoea and increased thickness of the large bowel wall, with P<0.5. Another extremely significant correlation we observed is the one between increased thickness of large bowel wall and loss of layering at this level, with P<0.5. Upper GI endoscopy revealed that dilated lacteals in the duodenum are significantly associated with the presence of diarrhoea, P<0.5 and, more... |

| Anatomical variations of the sternocleidomastoid muscle are rare and concern its origin, insertion, and the number of heads. We report on a rare bilateral variant of the sternocleidomastoid muscle with aberrant and supernumerary muscular heads, observed in a cadaveric subject. On the right side of the neck, a typical sternomastoid head of the sternocleidomastoid muscle, and three aberrant clavicular heads of variable thickness, origin, and termination were noticed. On the left side, two sternomastoid heads were present; the medial one was of typical pattern, while the lateral was supernumerary. The cleidomastoid portion of the left sternocleidomastoid muscle was fused with the double sternomastoid segment. A strap-like muscle originating from the middle... |

| Myocardial contrast echocardiography has been used for assessing myocardial perfusion. Some concerns regarding its safety still remain, mainly regarding the induction of microvascular alterations. We sought to determine the bioeffects of microbubbles and real-time myocardial contrast echocardiography (RTMCE) in a closed-chest canine model. Eighteen mongrel dogs were randomly assigned to two groups. Nine were submitted to continuous intravenous infusion of perfluorocarbon-exposed sonicated dextrose albumin (PESDA) plus continuous imaging using power pulse inversion RTMCE for 180 min, associated with manually deflagrated high-mechanical index impulses. The control group consisted of 3 dogs submitted to continuous imaging using RTMCE without PESDA, 3 dogs... |

| ABSTRACT The aim of this study was to determine the vascular indices of adrenal blood flow in healthy dogs (systolic velocity - SV; diastolic velocity - DV; resistance index - RI). Eighteen dogs (thirty six adrenal) were studied. Physical examination, biochemical profile and dexamethasone suppression test were performed to determine general health status. Echotexture, size, contours and margins, and overall shape of the adrenal gland (right and left) were assessed via ultrasound. By spectral Doppler of the phrenic-abdominal artery, the SV, DV, and RI were acquired. Animals did not show alterations in clinical and laboratory examination and suppression of cortisol. Normal homogeneous and echotexture, regular contours and margins and normal shape and size... |

| This paper aims to compare the therapeutic effect of the laser As-Ga of 904nm and pulsed Ultrasound of 1 MHz applied in striated skeletal muscle of inflamed rats. The animals received an intramuscular injection of bupivacaine hydrochloride in tibialis muscle in order to induce the inflammatory process, and after 24 hours, the time was considered 0 for the initiation of therapy, using a laser and ultrasound. Samples collected the muscles of the animals were stained with Hematoxylin-Eosin and histological sections of the groups used for the analysis of the muscle tissue in relation to reducing the inflammatory process, comparing the results of the two therapies used. In this study it is suggested that both treatment with laser as with ultrasound can act as... |

| Abstract The aim of this study was to investigate the effectiveness of ultrasound as a conservation method for the inactivation of Escherichia coli inoculated into cactus pear juices (green and purple). Total soluble solids, pH, titratable acidity, and the kinetics of E. coli in cactus pear juices treated by ultrasound (60%, 70%, 80% and 90% amplitude levels for 1, 3 and 5 min) were evaluated over 5 days. Total inactivation was observed in both fruit juices after 5 min of ultrasound treatment at most amplitude levels (with the exception of 60% and 80%). After one and two days of storage, the recovery of bacteria counts was observed in all cactus pear juices. Ultrasound treatment at 90% amplitude for 5 min resulted in non-detectable levels of E. coli in... |

| The urinary bladder infection, having glucose-fermentingmicroorganisms such as pathogens is the disease called asemphysematous cystitis. These microorganism are ableto produce balls of gas in the bladder lumen. The mostfrequent bacteria associated with this pathology are: Proteussp, Aerobacteraerogenous, Escherichia coli and Clostridiumspp. The causes are nonspecific and are usually secondary toseveral conditions as diabetes mellitus, hyperadrenocorticism,anatomical defects, urolithiasis, tumours, prolongedcorticosteroid therapy, bladder wall thickening caused by chronicinflammation, and not ruling out the possibility of reportsin dogs not diabetic. The clinical sings are also nonspecific:dysuria, hematuria, urinary frequency, abdominal pain,apathy.... |

| ABSTRACT: Enzymatic hydrolysis (pepsin) assisted with or without ultrasound in the functional properties of hydrolyzates from different collagens were analyzed. Degree of hydrolysis, antioxidant activity (DPPH) and antimicrobial activity (MIC) were assessed. The treatment that resulted in greater antioxidant activity for the fiber sample was with the use of 4% of enzyme and concomitant ultrasound (40.7%), leading to a degree of hydrolysis of 21.7%. For the powdered fiber sample the hydrolysis treatment with use of 4% of enzyme resulted in lower protein content (6.97mg/mL), higher degree of hydrolysis (19.9%) and greater antioxidant activity (38.6%). The hydrolyzates showed inhibitory capacity against gram-negative bacteria Salmonella choleraesuis and... |
