Genomic characterization of the Braque Français type Pyrénées dog and relationship with other breeds

2018

The evaluation of genetic variability is a useful research tool for the correct management of selection and conservation strategies in dog breeds. In addition to pedigree genealogies, genomic data allow a deeper knowledge of the variability and genetic structure of populations. To date, many dog breeds, such as small regional breeds, still remain uncharacterized. Braque Français type Pyrénées (BRA) is a dog breed originating from a very old type of gun-dog used for pointing the location of game birds to hunters. Despite the ancient background, the knowledge about levels of genetic diversity, degree of inbreeding and population structure is scarce. This may raise concerns on the possibility …

Histological and morphometric study of the components of the sinus and atrioventricular nodes in horses and dogs

2019

Abstract The cardiac nodes are the source of the electrical impulse that is transmitted to the heart, the aim of this work is study the histological and morphometric characteristics of the different components of the sinus and atrioventricular nodes in horses and dogs that help to know the physiopathology of these nodes. A group of ten horse hearts and five dog hearts were used. The region of the sinus and atrioventricular nodes was sectioned serially, and the block of tissue removed for study. The samples were assessed using a morphometric analysis with the Image-Pro Plus 7.1 software and the acquisition of the images using a Leica DMD108 optic microscope. The shape of the horse's sinus no…

CNGB3 mutations account for 50% of all cases with autosomal recessive achromatopsia

2005

Contains fulltext : 47591.pdf (Publisher’s version ) (Closed access) Achromatopsia is a congenital, autosomal recessively inherited disorder characterized by a lack of color discrimination, low visual acuity (<0.2), photophobia, and nystagmus. Mutations in the genes for CNGA3, CNGB3, and GNAT2 have been associated with this disorder. Here, we analyzed the spectrum and prevalence of CNGB3 gene mutations in a cohort of 341 independent patients with achromatopsia. In 163 patients, CNGB3 mutations could be identified. A total of 105 achromats carried apparent homozygous mutations, 44 were compound (double) heterozygotes, and 14 patients had only a single mutant allele. The derived CNGB3 mutatio…

The taboo against group contact: Hypothesis of Gypsy ontologization

2007

The concept of this article is that the symbolic relationships between human beings and animals serve as a model for the relationships between the majority and the ethnic minority. We postulate that there are two representations that serve to organize these relationships between human beings and animals: a domestic and a wild one. If the domestic animal is an index of human culture, the wild animal is an index of nature which man considers himself to share with the animal. With the wild representation, contact with the animal will be taboo, as it constitutes a threat to the anthropological difference. We offer the hypothesis that ontologization of the minority, that is, the substitution of …

[Mediterranean spotted fever in paediatric and adult patients: two clinical aspects of the same disease].

2012

Mediterranean Spotted Fever is an acute febrile disease caused by Rickettsia conorii and transmitted to humans by the brown dog tick Rhipicephalus sanguineus. Nearly 400 cases are reported every year in Sicily, mainly from June to September. The aim of this study is to compare the clinical and laboratory features of two different groups of patients , one of adults and one of children. The analysis included all adult patients with MSF diagnosed at the Institute of Infectious Diseases, Paolo Giaccone University Polyclinic in Palermo, during the period January 2007- August 2010 and all the children diagnosed with MSF at the G. Di Cristina Children Hospital in Palermo during the period January …

What motivates arrangements of dog visits in nursing homes? Experiences by dog handlers and nurses

2017

Abstract Introduction Dog visits to nursing homes are used as a structured approach for enhancing residents' well-being. Few studies have emphasized the perspectives of the organizers. The purpose of the present study was to gain insight into the experiences of volunteer dog handlers and nurses involved in dog visits to nursing homes, focusing on what motivated them to contribute and identifying possible factors to successful dog visits. Methods Individual, in-depth interviews with eight dog handlers and group interviews with 10 nurses from four nursing homes. Results Feelings of meaningfulness and joy motivated both the dog handlers and nurses to arrange dog visits to nursing homes. Succes…

Regional distribution of opioidergic nerves in human and canine prostates

1989

The regional distribution of opioidergic nerves in the juvenile and adult human prostate and in the adult canine prostate has been studied immunohistochemically using well-characterized polyclonal antisera against multiple opioid peptides. Nerves displaying immunoreactivity (ir) for the proenkephalin (PRO-ENK) derivatives met-enkephalin (ME), leuenkephalin (LE), octapeptide, and heptapeptide (ordered in decreasing frequency) were present in the dorsolateral stroma of human prostate. In canine prostate, the situation was similar, but the number of opioid-ir nerve fibers was lower than in human prostate. In both species, staining for the prodynorphin (PRO-DYN) derivatives dynorphin A and alph…

Ileocecal valve reconstruction during continent urinary diversion.

1994

During construction of an ileocecal reservoir, such as the Mainz or Indiana pouch, the ileocecal valve is lost. Subsequently, the intestinal transit time is shortened and malabsorption as well as diarrhea may result. Patients having undergone previous bowel resection as well as children with myelomeningocele who often already have frequent defecations will be heavily affected by the loss of the ileocecal valve. We have functionally reconstructed the ileocecal valve by embedding ileum into the ascending colon via a submucosal tunnel in analogy to the technique used when creating the continence mechanism during the Mainz pouch procedure using the appendix. Experimental results in 15 dogs demo…

The Buccal Mucosal Graft For Urethral Reconstruction: A Preliminary Report

1992

Autologous buccal mucosa as a substitute for urethral epithelium was studied in 2 dogs and used in 6 patients with difficult urethral reconstruction problems. The indications for an operation in these patients were failed hypospadias repairs with limited skin in 3, severe structure disease after hypospadias repair in 1, a short urethra in 1 and epispadias in 1. Three urethral fistulas and 1 meatal stenosis occurred in 3 patients. No urethral stricture or diverticulum was noted, and the final outcome was good functionally and cosmetically in all patients. This technique is useful for urethral reconstruction when local skin is not available.
