an acute animal model of aortic stenosis: initial attempts at leaflet modification.percutaneous valve insertion is an emerging treatment for aortic stenosis (as). to date, no large animal model exists that replicates human calcific as; moreover, the absence of any valve pathology in currently available animal models prevents their use in any realistic assessment of percutaneous aortic valve therapy. hence, the aim of the present study was to create an acute large animal model in which human calcific as could be simulated.201222645851
cadmium-induced changes in genomic dna-methylation status increase aneuploidy events in a pig robertsonian translocation model.although cadmium is a well-established human carcinogen, the mechanisms by which it induces cancer are poorly understood. it is suggested that cadmium-mediated carcinogenesis may include the modulation of gene expression and signal-transduction pathways, interference with antioxidant enzymes, inhibition of dna repair and dna methylation, and induction of apoptosis. nevertheless, no predominant mechanism playing a role in metal-induced carcinogenesis has been reported. in the present study, we us ...201222640880
novel approach to therapeutic ercp after long-limb roux-en-y gastric bypass surgery using transgastric self-expandable metal stents: experimental outcomes and first human case study (with videos).ercp in roux-en-y gastric bypass (rygb) patients is challenging. balloon-assisted enteroscopy (bae) allows access to the excluded stomach with creation of a percutaneous endoscopic gastrostomy (peg). transgastric self-expandable metal stent (sems) placement may allow antegrade ercp in 1 session.201222624815
early superoxide scavenging accelerates renal microvascular rarefaction and damage in the stenotic kidney.renal artery stenosis (ras), the main cause of chronic renovascular disease (rvd), is associated with significant oxidative stress. chronic rvd induces renal injury partly by promoting renal microvascular (mv) damage and blunting mv repair in the stenotic kidney. we tested the hypothesis that superoxide anion plays a pivotal role in mv dysfunction, reduction of mv density, and progression of renal injury in the stenotic kidney. ras was induced in 14 domestic pigs and observed for 6 wk. seven ras ...201222622460
do pharmacokinetics explain persistent restenosis inhibition by a single dose of paclitaxel?the purpose of this study was to investigate the elimination of paclitaxel from the arterial wall after a single short administration with a coated balloon.201222619258
reduced aluminum contamination decreases parenteral nutrition associated liver injury.parenteral nutrition-associated cholestasis remains a significant problem, especially for the surgical neonates. aluminum is a toxic element known to contaminate parenteral nutrition. we hypothesize that parenterally administered aluminum causes liver injury similar to that seen in parenteral nutrition-associated cholestasis.201222595567
on-farm measurement of electrical conductivity for the estimation of ammonium nitrogen concentration in pig slurry.pig (sus scrofa domesticus) slurry (ps) is commonly applied as fertilizer to agricultural fields. knowledge of ps nitrogen content is essential for good management, but ps nitrogen content is highly variable, not only between farms but also within a farm. laboratory analysis of animal slurries is often expensive and impractical for routine farmer use. therefore, when slurry is spread on land, its fertilizer value is generally unknown, resulting in the risk of pollution. in this work, two rapid a ...201322565270
the choice of the intravenous fluid influences the tolerance of acute normovolemic anemia in anesthetized domestic pigs.the correction of hypovolemia with acellular fluids results in acute normovolemic anemia. whether the choice of the infusion fluid has an impact on the maintenance of oxygen (o₂) supply during acute normovolemic anemia has not been investigated so far.201222546374
efficiency of spatio-temporal vaccination regimes in wildlife populations under different viral constraints.classical swine fever (csf) is considered an endemic disease in european wild boar populations. in view of the high economic impact of the introduction of the virus into domestic pig units, huge efforts are invested in the preventive control of csf in wild boar populations. recent european community guidelines favour oral mass vaccination against csf in wild boar populations. the guidelines are explicit on the temporal structure of the vaccination protocol, but little is known about the efficacy ...201222530786
ischemic postconditioning at the initiation of cardiopulmonary resuscitation facilitates functional cardiac and cerebral recovery after prolonged untreated ventricular fibrillation.ischemic postconditioning (pc) with "stuttering" reintroduction of blood flow after prolonged ischemia has been shown to offer protection from ischemia reperfusion injury to the myocardium and brain. we hypothesized that four 20-s pauses during the first 3 min of standard cpr would improve post resuscitation cardiac and neurological function, in a porcine model of prolonged untreated cardiac arrest.201222521449
cloning and expression of porcine dicer and the impact of developmental stage and culture conditions on microrna expression in porcine embryos.microrna (mirna) is a class of small, single-stranded ribonucleic acids that regulate gene expression post-transcriptionally and are involved in somatic cell, germ cell, and embryonic development. as the enzyme responsible for producing mature mirna, dicer is crucial to mirna production. characterization of dicer and its expression at the nucleotide level, as well as the identification of mirna expression in reproductive tissues, have yet to be reported for the domestic pig (sus scrofa), a speci ...201222498362

the importance of craniofacial sutures in biomechanical finite element models of the domestic pig.craniofacial sutures are a ubiquitous feature of the vertebrate skull. previous experimental work has shown that bone strain magnitudes and orientations often vary when moving from one bone to another, across a craniofacial suture. this has led to the hypothesis that craniofacial sutures act to modify the strain environment of the skull, possibly as a mode of dissipating high stresses generated during feeding or impact. this study tests the hypothesis that the introduction of craniofacial suture ...201222363727
mri of auto-transplantation of bone marrow-derived stem-progenitor cells for potential repair of injured arteries.this study was to validate the feasibility of using clinical 3.0t mri to monitor the migration of autotransplanted bone marrow (bm)-derived stem-progenitor cells (spc) to the injured arteries of near-human sized swine for potential cell-based arterial repair.201222363566
disease severity declines over time after a wild boar population has been affected by classical swine fever--legend or actual epidemiological process?classical swine fever (csf) is a severe multi-systemic disease that can affect both domestic pigs and wild boar. past outbreaks in european wild boar involved high-virulent csf virus (csfv) strains and were mostly self-limiting. in these cases, morbidity and mortality rates were high in the affected regions. in contrast, endemic infections have been observed in several european wild boar populations in recent decades. morbidity and mortality rates were much lower despite the fact that outbreaks ...201222361000
methylation characteristics and developmental potential of guangxi bama minipig (sus scrofa domestica) cloned embryos from donor cells treated with trichostatin a and 5-aza-2'-deoxycytidine.summary reprogramming of dna methylation in somatic cell nuclear transfer (scnt) embryos is incomplete, and aberrant dna methylation patterns are related to the inefficiency of scnt. to facilitate nuclear reprogramming, this study investigated the effect of treating guangxi bama minipig donor cells with trichostatin a (tsa), 5-aza-2'-deoxycytine (5-aza-dc), or combination of tsa and 5-aza-dc prior to nuclear transfer. analyses showed that there were no major changes in cell-cycle status among al ...201322355002
linkage haplotype for allotypic variants of porcine iga and igg subclass genes.six putative subclasses of expressed porcine igg have been described from gene sequences and allotypic variants for five of these have been proposed. we tested this hypothesis by studying the transcription of these 11 variants in outbred hemizygous farm pigs. since cγ subclass genes are closely linked, they are most likely inherited as a haplotype. since hemizygous pigs can only express genes encoded on one chromosome, identifying the expressed genes can indicate which allelic variants are linke ...201222350166
non-cholinergic intervention of sarin nerve agent poisoning.the protective effects of selected anesthetic regimens on sarin (gb) were investigated in domestic swine. at 30% oxygen, the toxicity of this agent in isoflurane anesthetized animals (ld(50)=10.1μg/kg) was similar to literature sited values in awake swine (ld(50)=11.8μg/kg) and slightly higher than that of both ketamine (ld(50)=15.6μg/kg) and propofol (ld(50)=15.3μg/kg) anesthetized swine. use of 100% oxygen in ketamine anesthetized animals resulted in three-fold protective effects compared to 3 ...201222343375

performance of a novel dual-electrode bipolar radiofrequency ablation device: a chronic porcine study.: over recent years, a variety of energy sources, including bipolar radiofrequency, have been used to replace the traditional incisions of the cox-maze procedure for the surgical treatment of atrial fibrillation (af). the purpose of this study was to evaluate the safety and efficacy of a novel dual-electrode bipolar radiofrequency ablation device synergy (atricure, inc., cincinnati, oh usa) for af in a chronic porcine model.201122437797
identification of mitochondrial markers for genetic traceability of european wild boars and iberian and duroc pigs.iberian pigs and wild boars are the source of highly priced meat and dry-cured products. iberian maternal origin is mandatory for labeled iberian products, making necessary the authentication of their maternal breed origin. discrimination between wild and domestic pig maternal origin may be useful to distinguish labeled wild boar meat obtained from hunting or farming. in order to detect useful polymorphisms to trace iberian, duroc and wild boar maternal lineages, we herein investigated the compl ...200922444897
epicardial ablation on the beating heart: limited efficacy of a novel, cooled radiofrequency ablation device.objective: to perform a minimally invasive procedure for atrial fibrillation without cardiopulmonary bypass, it is necessary to create transmural lesions on the beating heart. although bipolar radiofrequency clamps can isolate the pulmonary veins, they have difficulty in performing any other left atrial lesions, particularly those of the traditional cox-maze procedure. this study examined the performance of an internally cooled, bipolar radiofrequency device designed for such an application. met ...200922323899
beating heart aortic valve replacement using real-time mri guidance.: the principal limitations of percutaneous techniques to replace the aortic valve are detailed visualization and durable prostheses. we report the feasibility of using real-time magnetic resonance imaging (mri) to provide precise anatomic detail and visual feedback to implant a proven bioprosthesis.200722436922
rational intraabdominal pressure monitoring: how to do it?intraabdominal hypertension (iah) is increasingly appreciated by intensivists as an important cause of organ dysfunction, even at pressure levels which were previously thought to be harmless. therefore, the goal of this review is to describe the different methods commonly used in clinical practice for intraabdominal pressure (iap) measurement, the advised methodology for each measurement method, and finally to give a rational approach for iap monitoring in daily clinical practice.200724881697
pheromonal transmission of an aversive experience in domestic pig.the process of spontaneous learning in an automatic food dispenser by a group of domestic female pigs was studied when one of the animals of the group had an aversive experience. restraining a gilt in the dispenser without access to food resulted in later avoidance of the system by other gilts, especially when the reactions of the restrained animal had been especially violent and associated with urination. the hypothesis of a delayed transmission of an unpleasant experience was tested. the food ...199224254286
social dominance relationships and spacing behavior of swine.dominance ranks were determined within each of eight pens of domestic swine, susscrofa. data on spacing and orientation of subjects were obtained from 16 mm time-lapse films and 35 mm overhead photographs with the aid of a digitizer assisted fortran program, disangl 2. dominance orders among subjects were relatively linear and stable. no pattern in pen location preferences (fixed space) was found but there were relationships between dominance rank and portable spacing patterns of the subjects. d ...198224895965
introduction of two chromosomal translocations of sus scrofa nigripes and sus scrofa scrofa into the genome of sus scrofa domestica.hybrids between wild and domestic pigs with two types of translocations in the karyotype were studied. the translocations of type i were first detected in a population of the middle asian wild boars. type ii was identified in a populations of the central european subspecies. a large number of middle asian and central european hybrids and their f1-f3 hybrids from crosses with domestic pigs were viable. by means of differential chromosome staining, the mechanism of the formation of 'synthetic' kar ...197824309902
chromosome translocations in the karyotypes of wild boars sus scrofa l. of the european and the asian areas of ussr.the karyotypes of the 80 wild boars of the four subspecies, sus scrofa ussuricus heude from the far east of ussr, s. s. nigripes blanf. from kirghizia (the middle asia), s. s. attila thos. from azerbaijan, s. s. ferus from lithuania, byelorussia and central russia, and the 44 domestic pigs of the five different breeds (vietnamese black, siberian omskaja gray, kakhethian-aborigen georgian, mangalica hungarian, landrace swedish), were studied by the giemsa banding method. differential staining by ...197524419506
