Reproducibility and Feasibility of Classification and National Guidelines for Histological Diagnosis of Canine Mammary Gland Tumours: A Multi-Institutional Ring Study.

Histological diagnosis of Canine Mammary Tumours (CMTs) provides the basis for proper treatment and follow-up. Nowadays, its accuracy is poorly understood and variable interpretation of histological criteria leads to a lack of standardisation and impossibility to compare studies. This study aimed to quantify the reproducibility of histological diagnosis and grading in CMTs.

Canine and feline in situ mammary carcinoma: A comparative review.

Carcinoma in situ of the breast is a well-known entity in humans. In veterinary medicine, particularly in canine and feline mammary literature, there is no agreement whether the term in situ should be used to indicate a specific carcinoma histotype or the noninvasive status of a carcinoma of any histotype. Moreover, in the most recent histologic classification of mammary tumors published by the Davis-Thompson Foundation, it is suggested to abandon the term carcinoma in situ given the lack of standardized criteria defining this entity, replacing it with epitheliosis or ductal/lobular hyperplasia with severe atypia.

Vet-ICD-O-Canine-1, a System for Coding Canine Neoplasms Based on the Human ICD-O-3.2.

Cancer registries are fundamental tools for collecting epidemiological cancer data and developing cancer prevention and control strategies. While cancer registration is common in the human medical field, many attempts to develop animal cancer registries have been launched over time, but most have been discontinued. A pivotal aspect of cancer registration is the availability of cancer coding systems, as provided by the International Classification of Diseases for Oncology (ICD-O).

Implication of the NLRP3 Inflammasome in Bovine Age-Related Sarcopenia.

Sarcopenia is defined as the age-related loss of skeletal muscle mass, quality, and strength. The pathophysiological mechanisms underlying sarcopenia are still not completely understood. The aim of this work was to evaluate, for the first time, the expression of NLRP3 inflammasome in bovine skeletal muscle in order to investigate the hypothesis that inflammasome activation may trigger and sustain a pro-inflammatory environment leading to sarcopenia.

Infrarenal Abdominal Aortic Aneurysm Endovascular Treatment: Long-term Results From a Single-Center Experience in an Unselected Patient Population.

Background: The aim of the present study was to evaluate early-, mid-, and long-term outcomes in an unselected population of patients treated for abdominal aortic aneurysms (AAAs) by endovascular aneurysm repair (EVAR) with different commercially available off-the-shelf devices.

Materials And Methods: A retrospective study was conducted on a prospectively compiled computerized database on patients presenting an infrarenal AAA treated between January 2008 and December 2015 in a high-volume Italian tertiary referral Center. Demographic, clinical, and specific morphological features were considered as potentially influencing the outcomes and the type of the implanted device.

Endovascular Treatment of an Anterior Tibial Artery Pseudoaneurysm Secondary to Penetrating Trauma in a Young Patient: Case Report and Literature Review.

We report a case of an 18-year-old woman who developed a delayed pseudoaneurysm of the right anterior tibial artery (ATA), 14 days after a knife accidental trauma. The patient was admitted to our emergency department for acute onset of pain in the right limb after a domestic trauma. At a physical examination, the limb was tense and tender, with a pulsatile mass in the anterior compartment.

Unexpected Complication of a Nitinol-Constrained Balloon Angioplasty (Chocolate) in Rutherford Class 3 Patient Presenting Challenging Aorto-Iliac Anatomy.

We report an unusual complication of Chocolate nitinol-constraining structure after right superficial femoral artery (SFA) angioplasty. The procedure was performed by vascular surgeons in an operating theater equipped by a portable fluoroscopy unit. Under local anesthesia, by a contralateral approach, a 7F introducer sheath was advanced through the proximal portion of the right common iliac artery.

Anatomical variations of cervical vein drainage in candidates for neck surgery.

Unlabelled: The knowledge of both normal and abnormal anatomy of the veins of the neck may be important for surgeons performing neck surgery, to avoid inadvertent injury to vascular structures. In a 75-year-old man candidated to carotid endarterectomy preoperative CT-scan showed a rare anomaly of the venous drainage in the area of the anterior jugular vein (AJV), that usually begins in the suprahyoid region via the confluence of several superficial veins, to open into the ipsilateral external jugular vein. A large left sided venous trunk, originating from an anomalous proximal confluence with the internal jugular vein, descended in the AJV anatomical position, to cross over the sternum draining into the right subclavian vein.

Wounding tomato fruit elicits ripening-stage specific changes in gene expression and production of volatile compounds.

Fleshy fruits develop from an unripe organ that needs to be protected from damage to a ripe organ that attracts frugivores for seed dispersal through production of volatile organic compounds (VOCs). Thus, different responses to wounding damage are predicted. The aim of this study was to discover whether wound-induced changes in the transcriptome and VOC production alter as tomato transitions from unripe to ripe.

Coxiella burnetii lipopolysaccharide blocks p38α-MAPK activation through the disruption of TLR-2 and TLR-4 association.

To survive in macrophages, Coxiella burnetii hijacks the activation pathway of macrophages. Recently, we have demonstrated that C. burnetii, via its lipopolysaccharide (LPS), avoids the activation of p38α-MAPK through an antagonistic engagement of Toll-like receptor (TLR)-4.

Spirocerca lupi infection in a dog from southern Italy: an "old fashioned" disease?

Canine spirocercosis caused by Spirocerca lupi is a life-threatening helminthic disease featured by severe clinical signs and potential development of oesophageal neoplasia. This infection is considered fairly frequent in Europe but almost unknown in Italy, from where only few reports have been published in local journals at the beginning of the XXI century. In the present study, an autochthonous case of canine spirocercosis in a 2-year-old dog from southern Italy is described.

Haplotype characterization and markers at the barley Mlo powdery mildew resistance locus as tools for marker-assisted selection.

Recessive mlo alleles of the barley Mlo gene confer resistance to almost all known isolates of the powdery mildew fungal pathogen targeting barley (Hordeum vulgare). To characterize haplotypes present in the Mlo chromosomal region of cultivated Mlo and mlo barley genotypes, we conducted a polymorphism search in 3 predicted low-copy sequence regions adjacent to the Mlo gene by examining a sample of 4 Mlo and 3 mlo cultivars. Eight single-nucleotide polymorphisms (SNPs) and 1 insertion-deletion (indel) were detected, and easy to use PCR-based markers were developed for typing the SNPs.

Reconstruction of parodontal tissue with chitosan.

Chitosan ascorbate, obtained by mixing chitosan with ascorbic acid and sodium ascorbate, was produced in a gel form suitable for the treatment of periodontitis according to current dental surgery. While chitosan ascorbate underwent degradation in vitro, especially in the presence of atmospheric oxygen and at pH 6.0, the protection from oxygen offered by the surgical cements and the physiological pH value permitted chitosan ascorbate to play an important biological role in vivo, where it kept a honeycomb structure, as indicated by SEM on biopsies taken on 10 patients.

[Bleaching of a vital upper central incisor].

One trauma can elicit tooth vitality loss, even partial. The pulpal tissue necrosis, that is produced, causes darkening of the tooth. We can return this teeth to its original color using the bleaching technique.

Biological activity of chitosan: ultrastructural study.

Reparative processes are reconstructive phenomena in which cellular elements and extracellular matrix glycoproteins interact to build the injured tissue. Biomaterials can be used to improve or stimulate reconstruction. In the present experimental investigation, tissue repair induced by chitosan, an 86.

Changes in bilirubin transport across the liver by the flavonoids (+)-cyanidanol-3 and palmitoyl-catechin.

The apparent maximal transport capacity (Tm) of the liver for bilirubin was studied in rats after oral treatment for two weeks with the two flavonoids (+)-cyanidanol-3 and palmitoyl-catechin in order to investigate a possible mechanism of action on jaundice described in humans. (+)-Cyanidanol-3 produces no changes in bilirubin-Tm, and the analysis of bilirubin and its conjugates in the different compartments reveals a decreased amount of the whole bilirubin taken up by the liver. Palmitoyl-catechin, a more lipophilic derivative of catechin, produces a slight increase in bilirubin-Tm.
