Dystrophin Threshold Level Necessary for Normalization of Neuronal Nitric Oxide Synthase, Inducible Nitric Oxide Synthase, and Ryanodine Receptor-Calcium Release Channel Type 1 Nitrosylation in Golden Retriever Muscular Dystrophy Dystrophinopathy.

At present, the clinically most advanced strategy to treat Duchenne muscular dystrophy (DMD) is the exon-skipping strategy. Whereas antisense oligonucleotide-based clinical trials are underway for DMD, it is essential to determine the dystrophin restoration threshold needed to ensure improvement of muscle physiology at the molecular level. A preclinical trial has been conducted in golden retriever muscular dystrophy (GRMD) dogs treated in a forelimb by locoregional delivery of rAAV8-U7snRNA to promote exon skipping on the canine dystrophin messenger.

Role of Wheat Based Diet on the Pathology of Necrotic Enteritis in Turkeys.

The study was conducted to investigate the effects of wheat based diet on the pathology of necrotic enteritis in turkeys. Turkeys were divided into four groups. Groups A and B were kept as noninoculated and fed normal commercial diet while groups C and D were challenged orally with C.

Prevalence of Coccidiosis in Free-Range Chicken in Sidi Thabet, Tunisia.

Background. Enteric diseases are an important concern to the poultry industry and coccidiosis is imposing a significant economic burden worldwide. Objectives.

Production and characterization of monoclonal antibodies specific for canine CD138 (syndecan-1) for nuclear medicine preclinical trials on spontaneous tumours.

We isolated 11 antibodies specific for canine CD138 (cCD138) to validate the interest of CD138 antigen targeting in dogs with spontaneous mammary carcinoma. The affinity of the monoclonal antibodies in the nanomolar range is suitable for immunohistochemistry and nuclear medicine applications. Four distinct epitopes were recognized on cCD138 by this panel of antibodies.

Digestive sensitivity varies according to size of dogs: a review.

Field observations on food tolerance have repeatedly shown that when fed an identical diet, large breed (>25 kg) dogs present softer and moister faeces than small breed ones (<15 kg). The purpose of this review is to highlight the findings of four PhD theses, carried out between 1998 and 2013, whose objectives were to investigate the anatomical and physiological peculiarities that would explain, at least in part, this observation, as well as their nutritional implication. This work showed that large breed dogs, in contrast with smaller breeds, present a highly developed caecum and colon, which could explain the relatively longer colonic transit time.

Integration of microbiology and infectious disease teaching courses in an interdisciplinary training programme (Master level) centred on the 'One world, one health' WHO concept.

This report describes the integration of the microbiology and infectious diseases teaching courses in an international Master's level interdisciplinary programme based on the 'One world, one health' WHO concept, and reports the students and teachers' evaluation related to their feelings of about this innovative programme. The integration was evaluated by recording the positioning of these two topics in the five teaching units constituting the programme, and by identifying their contribution in the interactions between the different teaching units. The satisfaction of students was assessed by a quantitative survey, whereas the feelings of students and teachers were assessed by interviews.

Comparison of gas chromatography-mass spectrometry and gas chromatography-combustion-isotope ratio mass spectrometry analysis for in vivo estimates of metabolic fluxes.

Gas chromatography-mass spectrometry (GC-MS) was compared with gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS) for measurements of cholesterol (13)C enrichment after infusion of labeled precursor ([(13)C1,2]acetate). Paired results were significantly correlated, although GC-MS was less accurate than GC-C-IRMS for higher enrichments. Nevertheless, only GC-MS was able to provide information on isotopologue distribution, bringing new insights to lipid metabolism.

Caprine arthritis encephalitis: an example of risk assessment for embryo trading.

The risk of transmission of caprine arthritis encephalitis virus (CAEV) during embryo transfer has been demonstrated in vivo through the detection of CAEV proviral DNA in: (1) flushing media for embryo collection; (2) cells of the cumulus oophorus surrounding the oocytes, ovarian follicle, oviduct and uterine tissues; and (3) testis, epididymis, vas deferens and vesicular glands. Experimentally infected embryos without a zona pellucida (ZP), washed 10 times with Minimum Essential Media (MEM) and 5% Fetal Calf Serum (FCS) solution, were capable of transmitting CAEV. In vitro we demonstrated that granulosa, oviductal, epididymal and embryo cells are fully susceptible to CAEV infection and allow active replication.

Description of Campylobacter jejuni Bf, an atypical aero-tolerant strain.

Background: Campylobacter jejuni is a leading cause of bacterial enteritis worldwide. This microaerophilic bacterium can survive in aerobic environments, suggesting it has protective mechanisms against oxidative stress. The clinical C.

Aglepristone: A review on its clinical use in animals.

Aglepristone (RU 46534) is a competitive progesterone antagonist that is indicated for the treatment of various progesterone-dependent physiological or pathologic conditions. Aglepristone has proven to be an effective means of terminating pregnancy in most species. When used to induce parturition, aglepristone was effective in all cases in the bitch, cow, and goat, with no apparent adverse effects on neonatal health or milk production.

Nicotinic Acid Accelerates HDL Cholesteryl Ester Turnover in Obese Insulin-Resistant Dogs.

Aim: Nicotinic acid (NA) treatment decreases plasma triglycerides and increases HDL cholesterol, but the mechanisms involved in these change are not fully understood. A reduction in cholesteryl ester transfer protein (CETP) activity has been advanced to explain most lipid-modulating effects of NA. However, due to the central role of CETP in reverse cholesterol transport in humans, other effects of NA may have been hidden.

In vitro bovine embryo production in a synthetic medium: embryo development, cryosurvival, and establishment of pregnancy.

The aim of this study was to develop an in vitro embryo culture medium without either fetal calf serum or BSA, using various growth factors and cytokines (GFs-CYKs; IGF-I, IGF-II, bFGF, LIF, GM-CSF, TGF-β1, and PDGF-BB), and other molecules with surfactant and embryotrophic properties, such as recombinant albumin (RA) and hyaluronan (HA). The first part of the study was dedicated to define the best combination of GFs-CYKs + RA + HA for optimal embryonic development. Next, we compared development rates and embryo quality (inner cell mass [ICM]-to-total cell number [TCN] ratio), and postthaw survival and hatching rates using this synthetic medium (T1) and a control medium: synthetic oviduct fluid + BSA + ITS (insulin, transferrin, and selenium).

Fiber Composition of the Grasscutter (, Temminck 1827) Thigh Muscle: An Enzyme-histochemical Study.

The aim of this study was to describe de fiber composition in the thigh muscles of grass cutter (, Temminck 1827). Ten 4 to 6-month-old (3 to 4 kg) male grasscutter were used in this study. Eleven skeletal muscles of the thigh [M.

Large animal models for vaccine development and testing.

The development of human vaccines continues to rely on the use of animals for research. Regulatory authorities require novel vaccine candidates to undergo preclinical assessment in animal models before being permitted to enter the clinical phase in human subjects. Substantial progress has been made in recent years in reducing and replacing the number of animals used for preclinical vaccine research through the use of bioinformatics and computational biology to design new vaccine candidates.

Monitoring the Foetal Phase of Gestation in the Queen With a 12.5-MHz Ultrasound Probe and Prediction of the Parturition by Combining the Measurements of Head and Abdominal Diameters.

Ten gestations in six domestic shorthair cats (Europeans) were monitored daily during the foetal phase of gestation, from the 28th day after the first mating until parturition, using ultrasound with a 12.5-MHz probe. The development of the various organs over this period was recorded.

Efficient central nervous system AAVrh10-mediated intrathecal gene transfer in adult and neonate rats.

Intracerebral administration of recombinant adeno-associated vector (AAV) has been performed in several clinical trials. However, delivery into the brain requires multiple injections and is not efficient to target the spinal cord, thus limiting its applications. To assess widespread and less invasive strategies, we tested intravenous (IV) or intrathecal (that is, in the cerebrospinal fluid (CSF)) delivery of a rAAVrh10-egfp vector in adult and neonate rats and studied the effect of the age at injection on neurotropism.

Increased numbers of peripheral blood CD34+ cells in dogs with canine atopic dermatitis.

Background: The bone marrow may be involved in human atopic diseases, as shown by the release of CD34+ cells into the peripheral blood.

Hypothesis/objectives: The aim was to determine the numbers of CD34+ cells in atopic dogs.

Animals: The following three groups of dogs were studied: 27 dogs with nonfood-induced atopic dermatitis (NFICAD); 16 dogs with nonallergic inflammatory diseases; and 13 healthy control dogs.

Medical treatment for pyometra in dogs.

Pyometra is a reproductive disorder very common in bitches over 8 years of age in which physiological effects of progesterone on the uterus play a major role. The traditional therapy for pyometra is ovariohysterectomy. The main advantage of ovariohysterectomy over medical management is that it is both curative and preventive for recurrence of pyometra.

Cardiovascular effects of dietary salt intake in aged healthy cats: a 2-year prospective randomized, blinded, and controlled study.

High salt dry expanded diets are commercially available for cats to increase water intake and urine volume, as part of the prevention or treatment of naturally occurring urinary stone formation (calcium oxalates and struvites). However, chronic high salt intake may have potential cardiovascular adverse effects in both humans, especially in aging individuals, and several animal models. The objective of this prospective, randomized, blinded, and controlled study was to assess the long-term cardiovascular effects of high salt intake in healthy aged cats.

Early pregnancy diagnosis and monitoring in the queen using ultrasonography with a 12.5 MHz probe.

Eleven pregnancies in six queens were monitored daily from day 7 to day 28, corresponding to the end of the embryonic period, using ultrasonography with a 12.5 MHz probe. The first mating was considered as the presumed start of gestation, as has been described to be the case in 92.

Maternal supplementation with n-3 long chain polyunsaturated fatty acids during perinatal period alleviates the metabolic syndrome disturbances in adult hamster pups fed a high-fat diet after weaning.

Perinatal nutrition is thought to affect the long-term risk of the adult to develop metabolic syndrome. We hypothesized that maternal supplementation with eicosapentaenoic acid and docosahexaenoic acid during pregnancy and lactation would protect offspring fed a high-fat diet from developing metabolic disturbances. Thus, two groups of female hamsters were fed a low-fat control diet, either alone (LC) or enriched with n-3 long chain polyunsaturated fatty acids (LC-PUFA) (LO), through the gestational and lactation periods.

Temporal evolution of hepatic anatomy during gestation and growth in the sheep.

In mammals, the liver undergoes a series of spectacular anatomical changes during development, particularly in domestic ruminants. In all domestic mammals, the liver retracts cranially until it reaches its definitive diaphragmatic position; however, in the sheep, it also withdraws from the entire left side of the diaphragm and seems to rotate through 180°. An anatomical study reveals that the hepatic conformation evolves very little during this topographical change.

Risk of Coxiella burnetii transmission via embryo transfer using in vitro early bovine embryos.

Coxiella burnetii, an obligate intracellular bacterium of worldwide distribution, is responsible for Q fever. Domestic ruminants are the main source of infection for humans. The objectives of this study were to determine (1) whether C.

Evaluation of eight commercial dog diets.

Estimation of the quality of commercial diets is a topic of interest for the majority of dog owners. Recently, in a French consumer association magazine, an evaluation of eight dog commercial dry diets (from super-premium, basic-nutrition, private-label and economy brands) according to several nutritional criteria was published. The aims of the study were: (1) to evaluate the apparent digestibility of these diets; (2) to score these diets according to digestibility results; and (3) to compare these data with the scoring of the magazine.
