Primary Urinary Bladder Tumors in Three Guinea Pigs (Cavia Porcellus).

Urinary bladder tumors are not common in guinea pigs, but case numbers being diagnosed have increased in the past years. The authors present 3 referred cases of primary urinary bladder tumors in pet guinea pigs diagnosed using diagnostic imaging (CT, radiography, and ultrasonography) and exploratory laparotomy. Excision was not possible in the first case as the tumor was located at the neck of the urinary bladder and the owner opted for intraoperative euthanasia.

Albuminuria and proteinuria in dogs infected with Dirofilaria repens: A cross-sectional study.

Background: It is unknown whether Dirofilaria repens is capable of causing similar glomerular lesions, as does Dirofilaria immitis.

Objective: To determine whether D. repens infection could cause albuminuria or proteinuria.

Establishment of a reference interval for urinary albumin-to-creatinine ratio in dogs.

Background: Albuminuria is an important marker of renal damage and can precede proteinuria; thus, it can be a useful analyte in the early diagnosis of kidney diseases. Albuminuria has also been found in dogs with hypertension, inflammatory, infectious, and neoplastic diseases.

Objectives: The aim of this study was to establish a reference interval (RI) for albuminuria in dogs.

Occurrence of mitral valve insufficiency in clinically healthy Beagle dogs.

Chronic degenerative valve disease (CDVD) is the most common cardiac disease in dogs, usually resulting in mitral valve insufficiency (MVI). The goal of this study was to investigate the occurrence of MVI in clinically healthy Beagle populations. A total of 79 adult healthy Beagles (41 females and 38 males; age: 5.

Angiostrongylosis-related restrictive pneumopathy assessed by arterial blood gas analysis in a dog.

Pulmonary angiostrongylosis was diagnosed by the Baermann method and larval identification from faecal and bronchoalveolar lavage samples in a five-month- old male mongrel dog with dyspnoea and cough. Arterial blood gas analysis indicated arterial hypoxaemia and restrictive pneumopathy. In addition to the palliative treatment, fenbendazole was administered (50 mg/kg/24 h per os) for 14 days.

Comparison of traditional and sensor-based electronic stethoscopes in beagle dogs.

The objective of this study was to compare the auscultatory findings using traditional and electronic sensor-based stethoscopes. Thirty-three adult healthy Beagles (20 females, 13 males, mean age: 4.8 years, range 1.

Experimental results of using autologous rectus fascia sheath for venous patch grafts in dogs.

Autologous vascular patch grafts developed from the internal rectus sheath were implanted onto the bilateral common iliac vein and jugular vein of 4 experimental beagle dogs. During the development and implanting of the grafts no technical difficulties or perioperative complications were encountered. The follow-up lasted 6 months and 3 months in the case of the common iliac vein grafts and the jugular grafts, respectively.

Differential effect of ischaemic preconditioning on mobilisation and recruitment of haematopoietic and mesenchymal stem cells in porcine myocardial ischaemia-reperfusion.

Effects of ischaemic preconditioning (IP) on the mobilisation and recruitment of haematopoietic (HSCs) and mesenchymal stem (MSC) cells were determined in porcine coronary occlusion/reperfusion. Thirty-three pigs underwent percutaneous occlusion of the left anterior descending coronary artery (LAD) for 90 minutes (min), followed by 120 min reperfusion. IP was performed in 16 of the 33 pigs by two cycles of 5 min balloon occlusion/reperfusion prior to the 90 min occlusion (group IP vs.

Intracoronary injection of in situ forming alginate hydrogel reverses left ventricular remodeling after myocardial infarction in Swine.

Objectives: This study sought to determine whether alginate biomaterial can be delivered effectively into the infarcted myocardium by intracoronary injection to prevent left ventricular (LV) remodeling early after myocardial infarction (MI).

Background: Although injectable biomaterials can improve infarct healing and repair, the feasibility and effectiveness of intracoronary injection have not been studied.

Methods: We prepared a calcium cross-linked alginate solution that undergoes liquid to gel phase transition after deposition in infarcted myocardium.

Two-dimensional echocardiographic measurements of the left atrium in dogs with cardiac disease.

The aim of the present study was to verify the validity of two-dimensional echocardiographic (2DE) measurement technique in dogs with left atrial enlargement. Thirty-one dogs with clinically and echocardiographically proven cardiac diseases were randomly selected. The left atrial right-to-left diameter (La(r-l)) and the diameter of the left atrium just above the mitral annulus (La(ama)) as well as the ratio of left atrial to aortic diameter ( La/Ao ) were measured by 2DE.
