Tumour-to-Tumour Metastasis Phenomenon: Metastatic Prostatic Adenocarcinoma within an Anaplastic Oligodendroglioma in the Brain of a Dog.

A 10-year-old entire male French bulldog was presented following clusters of generalized tonic-clonic epileptic seizures. Neurolocalization was consistent with a lesion in the left forebrain. Magnetic resonance imaging of the brain revealed a large, ill-defined, intra-axial, space-occupying lesion at the level of the left temporal and parietal lobes, causing marked compression of the adjacent parenchyma.

Serum Symmetric Dimethylarginine as an Early Marker of Excretory Dysfunction in Canine Leishmaniosis Induced Nephropathy.

The aims of the study were to determine whether symmetric dimethylarginine (SDMA) was increased in dogs with leishmaniosis and to assess its relationship with creatinine concentration and urinary protein : creatinine ratio (UPC) to determine its utility as a marker of early excretory dysfunction. Fifty-three dogs with leishmaniosis classified according to the LeishVet clinical staging (stage I, = 5, stage II, = 30; stage III, = 12; stage IV, = 6) were selected and compared with 41 clinically healthy dogs. Thirty-nine dogs with leishmaniosis were also followed up for six months.

Cyclooxygenase-2 immunoexpression in intestinal epithelium and lamina propria of cats with inflammatory bowel disease and low grade alimentary lymphoma.

Background: Cyclooxygenase 2 (COX-2) is an inducible isoform by cellular activation, proinflammatory cytokines and growth factors. The aims of the current study were to evaluate COX-2 immunoexpression in epithelial and lamina propria (LP) of cats with inflammatory bowel disease (IBD) and low grade alimentary lymphoma (LGAL), as well as to correlate them with clinical signs and histopathological scoring. Cats diagnosed with IBD and LGAL (2007-2013) were included in the current study.

Clinicopathological findings in sick dogs naturally infected with Leishmania infantum: Comparison of five different clinical classification systems.

A wide spectrum of clinical and clinicopathological findings in dogs with canine leishmaniosis (CanL) due to Leishmania infantum exists. However, the majority of clinical descriptions have been published a long time ago and recent studies in Europe are almost lacking. In addition, clinical classification of sick dogs is not well-standardized, with different classification systems used by clinical and epidemiological studies, making comparison of studies a difficult task.

Extreme Tetralogy of Fallot With Polycythemia in a Ferret (Mustela putorius furo).

A 5-month-old, intact male ferret (Mustela putorius furo) was presented with apathy, tachypnea and exercise intolerance. On initial physical examination, tachypnea and cyanosis were the two primary clinical signs detected. The complete blood count also revealed a severe polycythemia, with lymphopenia, neutrophilia and eosinophilia.

Pine processionary caterpillar, Thaumetopoea pityocampa Denis and Schiffermüller, 1775 contact as a health risk for dogs.

Pine processionary, Thaumetopoea pityocampa Denis and Schiffermüller, 1775 is a moth that belongs to the order of insects Lepidoptera, and family Notodontidae. The larvae of pine processionary moth are the main pest of pines all over the world, but mainly in Mediterranean region. The contact with pine processionary caterpillar (lepidopterism) can produce a strong inflammatory reaction on skin and mucous membranes.

Canine leishmaniosis - an emerging disease.

Canine leishmaniosis (CanL) is an invasive disease of dogs, caused by Leishmania spp. parasites transmitted by the bite of an infected phlebotomine sand fly. CanL is declared an important disease by World Organisation for Animal Health (OIE).

Phenobarbital-responsive sialadenosis in dogs: case series.

Phenobarbital-responsive sialadenosis (PRS) is a rare idiopathic disease in dogs. Vomiting, retching, and gulping with bilateral enlargement of the submandibular salivary glands are the more frequent clinical signs. A thorough diagnostic examination must be performed to rule out the most important systemic etiologies involved with chronic vomiting, as there is no specific test to diagnose PRS.

Evaluation of the Relationship between Selected Reticulocyte Parameters and Inflammation determined by Plasma C-reactive Protein in Dogs.

Anaemia secondary to inflammatory disease is one of the main causes of anaemia in veterinary and human medicine and impairment of iron homeostasis due to the release of pro-inflammatory cytokines is one of the aetiological mechanisms involved. Because reticulocytes are recently produced cells, reticulocyte indices are early indicators of iron deficiency anaemia in man and dogs and reticulocyte indices may be affected during the course of inflammatory processes earlier than indices related to mature red blood cells. The aim of this study was to evaluate the possible influence of inflammation on reticulocyte parameters including concentration, mean reticulocyte volume, volume distribution width, percentage of microcytic reticulocytes, percentage of macrocytic reticulocytes, mean reticulocyte haemoglobin content (CHr), haemoglobin distribution width, cell haemoglobin concentration, mean percentage of hypochromic reticulocytes, percentage of reticulocytes with low CHr and immature reticulocyte factor medium and high, and on white blood cell concentration by using C-reactive protein (CRP) as an inflammatory biomarker.

Clinical assessment and C-reactive protein (CRP), haptoglobin (Hp), and cardiac troponin I (cTnI) values of brachycephalic dogs with upper airway obstruction before and after surgery.

Brachycephalic dogs have unique upper respiratory anatomy with abnormal breathing patterns that are similar to those in humans with obstructive sleep apnea syndrome (OSAS). The objectives of this multicenter prospective study were to assess the effects of surgical correction on clinical signs in dogs with brachycephalic airway obstructive syndrome (BAOS) and to evaluate the levels of several biomarkers [C-reactive protein (CRP); haptoglobin (Hp), and cardiac troponin I (cTnI)] used to determine systemic inflammation and myocardial damage. This study was conducted on 33 dogs with BAOS that were evaluated before and 1 to 2 mo after surgical correction.

Synthesis and properties of poly(L-lactide)-b-poly (L-phenylalanine) hybrid copolymers.

Hybrid materials constituted by peptides and synthetic polymers have nowadays a great interest since they can combine the properties and functions of each constitutive block, being also possible to modify the final characteristics by using different topologies. Poly(l-lactide-b-l-phenylalanine) copolymers with various block lengths were synthesized by sequential ring-opening polymerization of l-lactide and the N-carboxyanhydride of l-phenylalanine. The resulting block copolymers were characterized by NMR spectrometry, IR spectroscopy, gel permeation chromatography, MALDI-TOF and UV-vis, revealing the successful incorporation of the polyphenylalanine (PPhe) peptide into the previously formed poly(l-lactide) (PLLA) polymer chain.

Micro-molding with ultrasonic vibration energy: new method to disperse nanoclays in polymer matrices.

Ultrasound technology was proved as an efficient processing technique to obtain micro-molded specimens of polylactide (PLA) and polybutylene succinate (PBS), which were selected as examples of biodegradable polyesters widely employed in commodity and specialty applications. Operational parameters such as amplitude, molding force and processing time were successfully optimized to prepare samples with a decrease in the number average molecular weight lower than 6%. Ultrasonic waves also seemed an ideal energy source to provide effective disaggregation of clay silicate layers, and therefore exfoliated nanocomposites.

Methods: In this retrospective study, serum cTnI concentration was measured in dogs with leishmaniasis and in age-matched healthy dogs.

Mummified fetus in the thoracic cavity of a domestic short-haired cat.

This short communication describes the diagnosis, treatment, and clinical course of a domestic short-haired cat with diaphragmatic hernia in which the herniated structure in the thoracic cavity contained a mummified fetus. The cat was pregnant when rescued from the street and, days later, gave birth without abnormalities. Some months later, during an ovariohysterectomy, an abnormal localization of the uterus was observed, and at that time the case was referred to our center.

Evaluation of C-reactive protein, haptoglobin and cardiac troponin 1 levels in brachycephalic dogs with upper airway obstructive syndrome.

Background: Brachycephalic dogs have unique upper respiratory anatomy with abnormal breathing patterns similar to those in humans with obstructive sleep apnea syndrome (OSAS). The objective of this study was to evaluate the correlation between anatomical components, clinical signs and several biomarkers, used to determine systemic inflammation and myocardial damage (C-reactive protein, CRP; Haptoglobin, Hp; cardiac troponin I, cTnI), in dogs with brachycephalic upper airway obstructive syndrome (BAOS).

Results: Fifty brachycephalic dogs were included in the study and the following information was studied: signalment, clinical signs, thoracic radiographs, blood work, ECG, components of BAOS, and CRP, Hp and cTnI levels.

The order Bacillales hosts functional homologs of the worrisome cfr antibiotic resistance gene.

The cfr gene encodes the Cfr methyltransferase that methylates a single adenine in the peptidyl transferase region of bacterial ribosomes. The methylation provides resistance to several classes of antibiotics that include drugs of clinical and veterinary importance. This paper describes a first step toward elucidating natural residences of the worrisome cfr gene and functionally similar genes.
