advances in research in animal models of burn-related hypertrophic scarring.skin burn injuries affect approximately 500,000 people per year in france. after deep burns, functional sequelae associated with hypertrophic and retractile scars are an important public health problem. to understand the pathophysiology of sequelae and evaluate new therapeutic approaches, the use of animal models that should be standard tools is necessary. some pre-clinical models of hypertrophic scars after burns have been described, but the choice of the appropriate and relevant experimental m ...201525356852
immune modulation in xenotransplantation.the use of animals as donors of tissues and organs for xenotransplantations may help in meeting the increasing demand for organs for human transplantations. clinical studies indicate that the domestic pig best satisfies the criteria of organ suitability for xenotransplantation. however, the considerable phylogenetic distance between humans and the pig causes tremendous immunological problems after transplantation, thus genetic modifications need to be introduced to the porcine genome, with the a ...201425354539
anticipation and frequency of feeding affect heart reactions in domestic pigs.measuring heart reactions has become a widely used method for the assessment of emotions. heart rate and its variability, which can quite easily be noninvasively recorded, reflect the inputs of the sympathetic and parasympathetic branches of the autonomous nervous system. we tested the hypothesis that frequent anticipation of a positive event results in an increased state of welfare in pigs, expressed as positive arousal in anticipation of announced feeding as well as lowered heart rate and augm ...201425349338
pathogenic enterobacteria in lemurs associated with anthropogenic disturbance.as human population density continues to increase exponentially, speeding the reduction and fragmentation of primate habitat, greater human-primate contact is inevitable, making higher rates of pathogen transmission likely. anthropogenic effects are particularly evident in madagascar, where a diversity of endemic lemur species are threatened by rapid habitat loss. despite these risks, knowledge of how anthropogenic activities affect lemur exposure to pathogens is limited. to improve our understa ...201425328106
a genome-wide scan for selection signatures in yorkshire and landrace pigs based on sequencing data.pigs have experienced dramatic selection due to domestication, which has led to many different phenotypes when compared to their wild counterparts, especially in the last several decades. currently, genome-wide scans in both cattle and humans showing positive selection footprints have been investigated. however, few studies have focused on porcine selection footprints, particularly on a genome-wide scale. surveying for selection footprints across porcine genomes can be quite valuable for reveali ...201425327778
molecular epizootiology and diagnosis of porcine babesiosis in sardinia, italy.the recent characterization of the 18s ribosomal rna (rrna) of a pathogenic babesia species in a domestic sow paved the way for establishing diagnostic and epidemiological tools for porcine babesiosis. here, we developed the first specific babesia sp. suis pcr, and we applied this test to a panel of samples collected from animals living in a typical mediterranean environment (sardinia, italy), including domestic pigs, wild boars, and ticks. in domestic pigs, pcr coupled with sequencing revealed ...201425325315

immunohistochemical evidence of leptin and its receptor in the carpal glands of domestic pigs and wild boar.in recent years, the protein hormone leptin has been the subject of numerous studies designed to clarify and interpret its functional significance; it has been speculated that this goes well beyond the control of appetite and energy metabolism. in particular, the presence of leptin and its receptor has been observed in various glands anatomically and functionally related to the reproductive apparatus. this has led to the hypothesis that leptin may act directly in the functional control of these ...201525292333
phylogenetic analysis of hepatitis e virus in domestic swine and wild boar in germany.hepatitis e virus (hev) is an emerging non-enveloped positive strand rna virus with worldwide distribution that can cause acute liver disease in humans. the virus has also been detected in both domestic and wild animals. in this study we investigated the presence of hev in free-living wild boar as well as in domestic swine. a total of 105 domestic swine fecal samples and 124 wild boar sera were tested for the presence of hev rna by rt-pcr. a 241 nucleotide (nt) fragment from the capsid gene of h ...201425287630
expression of nk1 receptor at the protein and mrna level in the porcine female reproductive system.the presence and distribution of substance p (sp) receptor nk1 was studied in the ovary, the oviduct and the uterus (uterine horn and cervix) of the domestic pig using the methods of molecular biology (rt-pcr and immunoblot) and immunohistochemistry. the expression of nk1 receptor at mrna level was confirmed with rt-pcr in all the studied parts of the porcine female reproductive system by the presence of 525 bp pcr product and at the protein level by the detection of 46 kda protein band in immun ...201425286656
serological and virological survey of hepatitis e virus in wild boar populations in northwestern italy: detection of hev subtypes 3e and 3f.although rare in developed countries, most acquired human cases of hepatitis e virus (hev) infection are associated with travel to developing countries where hev is endemic. increasingly, however, sporadic, non-travel-related hev cases have been reported in developed countries. in italy, only two studies to date have investigated the presence of hev in wild boars. here, we report a serological and virological survey of hev in wild boar populations in northwestern italy. during the hunting season ...201525283611
in vivo tracking and immunological properties of pulsed porcine monocyte-derived dendritic cells.cellular therapies using immune cells and in particular dendritic cells (dcs) are being increasingly applied in clinical trials and vaccines. their success partially depends on accurate delivery of cells to target organs or migration to lymph nodes. delivery and subsequent migration of cells to regional lymph nodes is essential for effective stimulation of the immune system. thus, the design of an optimal dc therapy would be improved by optimizing technologies for monitoring dc trafficking. magn ...201525282042
anthelmintic efficacy of ivermectin and abamectin, administered orally for seven consecutive days (100 µg/kg/day), against nematodes in naturally infected pigs.the present study aimed to evaluate ivermectin and abamectin, both administered orally in naturally infected domestic swine, as well as analysing if the epg (eggs per gram of faeces) values were equivalent with the ivermectin and abamectin efficacy obtained by parasitological necropsies. the animals were randomly selected based on the average of three consecutive epg counts of strongylida, ascaris suum and trichuris for experiment i, and of strongylida and trichuris for experiment ii. after the ...201425278142
generation of crispr/cas9-mediated gene-targeted pigs via somatic cell nuclear transfer.the domestic pig has been widely used as an important large animal model. precise and efficient genetic modification in pig provides a great promise in biomedical research. recently, clustered regularly interspaced short palindromic repeat (crispr)/crispr-associated (cas) system has been successfully used to produce many gene-targeted animals. however, these animals have been generated by co-injection of cas9 mrna and single-guide rna (sgrna) into one-cell stage embryos, which mostly resulted in ...201525274063
influenza surveillance in animals: what is our capacity to detect emerging influenza viruses with zoonotic potential?a survey of national animal influenza surveillance programmes was conducted to assess the current capacity to detect influenza viruses with zoonotic potential in animals (i.e. those influenza viruses that can be naturally transmitted between animals and humans) at regional and global levels. information on 587 animal influenza surveillance system components was collected for 99 countries from chief veterinary officers (cvos) (n = 94) and published literature. less than 1% (n = 4) of these compon ...201525268692
effect of cyclic tension on the biomechanical properties of flexor tendon grafts. results of an ex-vivo porcine study.autologous flexor tendons are widely used for anterior cruciate ligament (acl) reconstruction. pretension of the graft before fixation has been described as part of the surgical technique, nevertheless there is no consensus on the type and amount to tension needed to increase the stiffness without affecting its biomechanical properties.our hypothesis is cyclic tension increases flexor tendon stiffness without affecting its ultimate failure at maximum loads (ufml).201425266942
catheter-based induction of renal ischemia/reperfusion in swine: description of an experimental model.several techniques to induce renal ischemia have been proposed: clamp, pva particles, and catheter-balloon. we report the development of a controlled, single-insult model of unilateral renal ischemia/reperfusion (i/r) without contralateral nephrectomy, using a suitable model, the pig. this is a balloon-catheter-based model using a percutaneous, interventional radiology procedure. one angioplasty balloon-catheter was placed into the right renal artery and inflated for 120 min and reperfusion over ...201425263203
dynamics of african swine fever virus shedding and excretion in domestic pigs infected by intramuscular inoculation and contact transmission.african swine fever virus (asfv) is a highly virulent swine pathogen that has spread across eastern europe since 2007 and for which there is no effective vaccine or treatment available. the dynamics of shedding and excretion is not well known for this currently circulating asfv strain. therefore, susceptible pigs were exposed to pigs intramuscularly infected with the georgia 2007/1 asfv strain to measure those dynamics through within- and between-pen transmission scenarios. blood, oral, nasal an ...201425256695
a comparative anatomic and physiologic overview of the porcine heart.despite advances during the last 2 decades in every aspect of cardiovascular research (interventional cardiology, cardiopulmonary resuscitation, and so forth), western societies still are plagued by the consequences of cardiovascular disease. consequently the discovery of new regimens and therapeutic interventions is of utmost importance. research using human subjects is associated with substantial methodologic and ethical considerations, and the quest for an appropriate animal model for the hum ...025255064
an in vivo three-dimensional magnetic resonance imaging-based averaged brain collection of the neonatal piglet (sus scrofa).due to the fact that morphology and perinatal growth of the piglet brain is similar to humans, use of the piglet as a translational animal model for neurodevelopmental studies is increasing. magnetic resonance imaging (mri) can be a powerful tool to study neurodevelopment in piglets, but many of the mri resources have been produced for adult humans. here, we present an average in vivo mri-based atlas specific for the 4-week-old piglet. in addition, we have developed probabilistic tissue classifi ...201425254955
development of a fatal noncompressible truncal hemorrhage model with combined hepatic and portal venous injury in normothermic normovolemic swine.noncompressible truncal hemorrhage and brain injury currently account for most early mortality of warfighters on the battlefield. there is no effective treatment for noncompressible truncal hemorrhage, other than rapid evacuation to a surgical facility. the availability of an effective field treatment for noncompressible truncal hemorrhage could increase the number of warfighters salvaged from this frequently-lethal scenario. our intent was to develop a porcine model of noncompressible truncal h ...201425251401
first report of corynebacterium pseudotuberculosis from caseous lymphadenitis lesions in black alentejano pig (sus scrofa domesticus).corynebacterium pseudotuberculosis is the etiologic agent of caseous lymphadenitis, a common disease in small ruminant populations throughout the world and responsible for a significant economic impact for producers.201425240511
multi-element analysis using inductively coupled plasma mass spectrometry and inductively coupled plasma atomic emission spectroscopy for provenancing of animals at the continental scale.chemical signatures within the environment vary between regions as a result of climatological, geochemical and anthropogenic influences. these variations are incorporated into the region's geology, soils, water and vegetation; ultimately making their way through the food chain to higher level organisms. because the variation in chemical signatures between areas is significant, a specific knowledge of differences in elemental distribution patterns between, and within populations, could prove bene ...201425240220
molecular epidemiology of mycoplasma hyopneumoniae from outbreaks of enzootic pneumonia in domestic pig and the role of wild boar.mycoplasma hyopneumoniae is the major cause of enzootic pneumonia (ep) in domestic pigs, a disease with low mortality but high morbidity, having a great economic impact for producers. in switzerland ep has been successfully eradicated, however, sporadic outbreaks are observed with no obvious source. besides the possibility of recurrent outbreaks due to persisting m. hyopneumoniae strains within the pig population, there is suspicion that wild boars might introduce m. hyopneumoniae into swine her ...201425236987
indirect genetic effects for growth rate in domestic pigs alter aggressive and manipulative biting behaviour.indirect genetic effects (iges) are heritable effects of an individual on phenotypic values of others, and may result from social interactions. we determined the behavioural consequences of selection for iges for growth (igeg) in pigs in a g × e treatment design. pigs (n = 480) were selected for high versus low igeg with a contrast of 14 g average daily gain and were housed in either barren or straw-enriched pens (n = 80). high igeg pigs showed from 8 to 23 weeks age 40% less aggressive biting ( ...201425227986
chest compressions do not disrupt the seal created by the laryngeal mask airway during positive pressure ventilation: a preliminary porcine study.pulmonary aspiration of gastric contents occurs 20 to 30% of the time during cardiopulmonary resuscitation (cpr) of cardiac arrest due to loss of protective airway reflexes, pressure changes generated during cpr, and positive pressure ventilation (ppv). although the american heart association has recommended the laryngeal mask airway (lma) as an acceptable alternative airway for use by emergency medical service personnel, concerns over the capacity of the device to protect from pulmonary aspirat ...201425227646
crossover of the hypothalamic pituitary-adrenal/interrenal, -thyroid, and -gonadal axes in testicular development.besides the well-known function of thyroid hormones (ths) for regulating metabolism, it has recently been discovered that ths are also involved in testicular development in mammalian and non-mammalian species. ths, in combination with follicle stimulating hormone, lead to androgen synthesis in danio rerio, which results in the onset of spermatogenesis in the testis, potentially relating the hypothalamic-pituitary-thyroid (hpt) gland to the hypothalamic-pituitary-gonadal (hpg) axes. furthermore, ...201425221542
effect of hypertransfusion on the gastrointestinal tract after cardiac arrest in a porcine model.this study aimed to determine the potential protective effect of inducing hypertransfusion to the gastrointestinal tract following a porcine model of cardiac arrest and cardiopulmonary resuscitation (cpr) by evaluating the influence of gastrointestinal ultrastructure, atpase and serum diamine oxidase.201225215039
outbreak of trichinella spiralis infections associated with a wild boar hunted at a game farm in iowa.rates of trichinellosis have declined significantly in the united states due to improved pork production practices and public awareness of the danger of eating raw or undercooked pork. in april 2011, the minnesota department of health received a report of presumptive trichinellosis in a 50-year-old man with a history of wild boar consumption. a public health investigation was initiated.201425214511
