collagenase promotes the cellular responses to injury and wound healing in vivo.this study focuses on the growth-promoting and migration-enhancing role that clostridial collagenase plays in vitro and in vivo.200516921413
increased sinusoidal flow is not the primary stimulus to liver regeneration.hemodynamic changes in the liver remnant following partial hepatectomy (phx) have been suggested to be a primary stimulus in triggering liver regeneration. we hypothesized that it is the increased sinusoidal flow per se and hence the shear-stress stimulus on the endothelial surface within the liver remnant which is the main stimulus to regeneration. in order to test this hypothesis we wanted to increase the sinusoidal flow without performing a concomitant liver resection. accordingly, we constru ...201020148099
physiologic compliance in engineered small-diameter arterial constructs based on an elastomeric substrate.compliance mismatch is a significant challenge to long-term patency in small-diameter bypass grafts because it causes intimal hyperplasia and ultimately graft occlusion. current engineered grafts are typically stiff with high burst pressure but low compliance and low elastin expression. we postulated that engineering small arteries on elastomeric scaffolds under dynamic mechanical stimulation would result in strong and compliant arterial constructs. this study compares properties of engineered a ...200919962188
the risk of extrapolation in neuroanatomy: the case of the mammalian vomeronasal system.the sense of smell plays a crucial role in mammalian social and sexual behaviour, identification of food, and detection of predators. nevertheless, mammals vary in their olfactory ability. one reason for this concerns the degree of development of their pars basalis rhinencephali, an anatomical feature that has been considered in classifying this group of animals as macrosmatic, microsmatic or anosmatic. in mammals, different structures are involved in detecting odours: the main olfactory system, ...200919949452
surgical porcine myocardial infarction model through permanent coronary occlusion.using domestic pigs as an animal model, we here validated a reproducible and standardized myocardial infarction (mi) surgical model, to achieve the largest possible infarct extent with the lowest morbidity and mortality. to this end, we included several anesthetic and perisurgical precautions to minimize surgical complications. mortality and morbidity rates were compared among groups of pigs that underwent permanent occlusion at different locations of either the left circumflex or left anterior ...022330353
characterization of porcine ventral mesencephalic precursor cells following long-term propagation in 3d culture.the potential use of predifferentiated neural precursor cells for treatment of a neurological disorder like parkinson's disease combines stem cell research with previous experimental and clinical transplantation of developing dopaminergic neurons. one current obstacle is, however, the lack of ability to generate dopaminergic neurons after long-term in vitro propagation of the cells. the domestic pig is considered a useful nonprimate large animal model in neuroscience, because of a better resembl ...201223258982
a gene expression atlas of the domestic pig.this work describes the first genome-wide analysis of the transcriptional landscape of the pig. a new porcine affymetrix expression array was designed in order to provide comprehensive coverage of the known pig transcriptome. the new array was used to generate a genome-wide expression atlas of pig tissues derived from 62 tissue/cell types. these data were subjected to network correlation analysis and clustering.201223153189
analyses of pig genomes provide insight into porcine demography and evolution.for 10,000 years pigs and humans have shared a close and complex relationship. from domestication to modern breeding practices, humans have shaped the genomes of domestic pigs. here we present the assembly and analysis of the genome sequence of a female domestic duroc pig (sus scrofa) and a comparison with the genomes of wild and domestic pigs from europe and asia. wild pigs emerged in south east asia and subsequently spread across eurasia. our results reveal a deep phylogenetic split between eu ...023151582
high-resolution autosomal radiation hybrid maps of the pig genome and their contribution to the genome sequence assembly.the release of the porcine genome sequence offers great perspectives for pig genetics and genomics, and more generally will contribute to the understanding of mammalian genome biology and evolution. the process of producing a complete genome sequence of high quality, while facilitated by high-throughput sequencing technologies, remains a difficult task. the porcine genome was sequenced using a combination of a hierarchical shotgun strategy and data generated with whole genome shotgun. in additio ...201223153393
strong signatures of selection in the domestic pig genome.domestication of wild boar (sus scrofa) and subsequent selection have resulted in dramatic phenotypic changes in domestic pigs for a number of traits, including behavior, body composition, reproduction, and coat color. here we have used whole-genome resequencing to reveal some of the loci that underlie phenotypic evolution in european domestic pigs. selective sweep analyses revealed strong signatures of selection at three loci harboring quantitative trait loci that explain a considerable part of ...201223151514
cathelicidins: family of antimicrobial peptides. a review.cathelicidins are small, cationic, antimicrobial peptides found in humans and other species, including farm animals (cattle, horses, pigs, sheep, goats, chickens, rabbits and in some species of fish). these proteolytically activated peptides are part of the innate immune system of many vertebrates. these peptides show a broad spectrum of antimicrobial activity against bacteria, enveloped viruses and fungi. apart from exerting direct antimicrobial effects, cathelicidins can also trigger specific ...201223065264

xenoantibody response to porcine islet cell transplantation using gtko, cd55, cd59, and fucosyltransferase multiple transgenic donors.promising developments in porcine islet xenotransplantation could resolve the donor pancreas shortage for patients with type 1 diabetes. using α1,3-galactosyltransferase gene knockout (gtko) donor pigs with multiple transgenes should extend xenoislet survival via reducing complement activation, thrombus formation, and the requirement for exogenous immune suppression. studying the xenoantibody response to gtko/hcd55/hcd59/hht islets in the pig-to-baboon model, and comparing it with previously ana ...201424645827
lapita diet in remote oceania: new stable isotope evidence from the 3000-year-old teouma site, efate island, vanuatu.remote oceania was colonized ca. 3000 bp by populations associated with the lapita cultural complex, marking a major event in the prehistoric settlement of the pacific islands. although over 250 lapita sites have been found throughout the western pacific, human remains associated with lapita period sites are rare. the site of teouma, on efate island, vanuatu has yielded the largest burial assemblage (n=68 inhumations) of lapita period humans ever discovered, providing a unique opportunity for as ...201424598939
assessment of regional ventilation distribution: comparison of vibration response imaging (vri) with electrical impedance tomography (eit).vibration response imaging (vri) is a bedside technology to monitor ventilation by detecting lung sound vibrations. it is currently unknown whether vri is able to accurately monitor the local distribution of ventilation within the lungs. we therefore compared vri to electrical impedance tomography (eit), an established technique used for the assessment of regional ventilation.201424475160
the role of viral and host micrornas in the aujeszky's disease virus during the infection process.porcine production is a primary market in the world economy. controlling swine diseases in the farm is essential in order to achieve the sector necessities. aujeszky's disease is a viral condition affecting pigs and is endemic in many countries of the world, causing important economic losses in the swine industry. micrornas (mirnas) are non-coding rnas which modulates gene expression in animals, plants and viruses. with the aim of understanding mirna roles during the aujeszky's disease virus [ad ...201424475202
domestication and the mitochondrial genome: comparing patterns and rates of molecular evolution in domesticated mammals and birds and their wild relatives.studies of domesticated animals have led to the suggestion that domestication could have significant effects on patterns of molecular evolution. in particular, analyses of mitochondrial genome sequences from domestic dogs and yaks have yielded higher ratios of non-synonymous to synonymous substitutions in the domesticated lineages than in their wild relatives. these results are important because they imply that changes to selection or population size operating over a short timescale can cause si ...024459286
substantial variation in the extent of mitochondrial genome fragmentation among blood-sucking lice of mammals.blood-sucking lice of humans have extensively fragmented mitochondrial (mt) genomes. human head louse and body louse have their 37 mt genes on 20 minichromosomes. in human pubic louse, the 34 mt genes known are on 14 minichromosomes. to understand the process of mt genome fragmentation in the blood-sucking lice of mammals, we sequenced the mt genomes of the domestic pig louse, haematopinus suis, and the wild pig louse, h. apri, which diverged from human lice approximately 65 ma. the 37 mt genes ...023781098
performance characteristics of qpcr assays targeting human- and ruminant-associated bacteroidetes for microbial source tracking across sixteen countries on six continents.numerous quantitative pcr assays for microbial fecal source tracking (mst) have been developed and evaluated in recent years. widespread application has been hindered by a lack of knowledge regarding the geographical stability and hence applicability of such methods beyond the regional level. this study assessed the performance of five previously reported quantitative pcr assays targeting human-, cattle-, or ruminant-associated bacteroidetes populations on 280 human and animal fecal samples from ...201323755882
insulin affects sperm capacity in pig through nitric oxide.insulin (ins) has recently been demonstrated to have the ability to induce the capacitation process in pig spermatozoa. in various mammalian species, capacitation has been linked to the nitric oxide (no) signalling; therefore, this study investigated no production in ins-treated pig spermatozoa by fluorescence-activated cell sorting. for the same samples, sperm capacitation was evaluated by chlortetracycline staining, protein tyrosine phosphorylation pattern and acrosomal status. a significant i ...201323728590
biological significance of urolithins, the gut microbial ellagic acid-derived metabolites: the evidence so far.the health benefits attributed to pomegranate have been associated with its high content in polyphenols, particularly ellagitannins. this is also the case for other ellagitannin-containing fruits and nuts including strawberry, raspberry, blackberry, walnuts, and muscadine grapes. the bioavailability of ellagitannins and ellagic acid is however very low. these molecules suffer extensive metabolism by the gut microbiota to produce urolithins that are much better absorbed. urolithins circulate in p ...201323781257
molecular investigation of torque teno sus virus in geographically distinct porcine breeding herds of sichuan, china.torque teno sus virus (ttsuv), infecting domestic swine and wild boar, is a non-enveloped virus with a circular, single-stranded dna genome. which has been classified into the genera iotatorquevirus (ttsuv1) and kappatorquevirus (ttsuv2) of the family anelloviridae. a molecular study was conducted to detect evidence of a phylogenic relationship between these two porcine ttsuv genogroups from the sera of 244 infected pigs located in 21 subordinate prefectures and/or cities of sichuan.201323705989
mild therapeutic hypothermia is superior to controlled normothermia for the maintenance of blood pressure and cerebral oxygenation, prevention of organ damage and suppression of oxidative stress after cardiac arrest in a porcine model.mild therapeutic hypothermia (ht) has been implemented in the management of post cardiac arrest (ca) syndrome after the publication of clinical trials comparing ht with common practice (ie, usually hyperthermia). current evidence on the comparison between therapeutic ht and controlled normothermia (nt) in ca survivors, however, remains insufficient.201323688243
reintroductions and genetic introgression from domestic pigs have shaped the genetic population structure of northwest european wild boar.population genetic studies focus on natural dispersal and isolation by landscape barriers as the main drivers of genetic population structure. however, anthropogenic factors such as reintroductions, translocations and wild x domestic hybridization may also have strong effects on genetic population structure. in this study we genotyped 351 single nucleotide polymorphism markers evenly spread across the genome in 645 wild boar (sus scrofa) from northwest europe to evaluate determinants of genetic ...201323688182
structural and functional annotation of the porcine immunome.the domestic pig is known as an excellent model for human immunology and the two species share many pathogens. susceptibility to infectious disease is one of the major constraints on swine performance, yet the structure and function of genes comprising the pig immunome are not well-characterized. the completion of the pig genome provides the opportunity to annotate the pig immunome, and compare and contrast pig and human immune systems.201323676093

wild boar: an increasing concern for aujeszky's disease control in pigs?the goal of this study was describing the temporal evolution of aujeszky's disease virus (adv) contact prevalence among eurasian wild boar (sus scrofa) populations under different management regimes and contact likelihoods with domestic pigs. given the recent increase in wild boar abundance throughout europe, we hypothesized that wild boar contact with adv would remain stable in time even after significant reduction of adv prevalence in domestic pigs.201222251441
the genome sizes of megabats (chiroptera: pteropodidae) are remarkably constrained.it has long been recognized that bats and birds contain less dna in their genomes than their non-flying relatives. it has been suggested that this relates to the high metabolic demands of powered flight, a notion that is supported by the fact that pterosaurs also appear to have exhibited small genomes. given the long-standing interest in this question, it is surprising that almost no data have been presented regarding genome size diversity among megabats (family pteropodidae). the present study ...200919324635
effect of betaine supplementation on power performance and fatigue.the purpose of this study was to examine the efficacy of 15 days of betaine supplementation on muscle endurance, power performance and rate of fatigue in active college-aged men.200919250531
lateral geniculate body evoked potentials elicited by visual and electrical stimulation.blind individuals who have photoreceptor loss are known to perceive phosphenes with electrical stimulation of their remaining retinal ganglion cells. we proposed that implantable lateral geniculate body (lgb) stimulus electrode arrays could be used to generate phosphene vision. we attempted to refine the basic reference of the electrical evoked potentials (eeps) elicited by microelectrical stimulations of the optic nerve, optic tract and lgb of a domestic pig, and then compared it to visual evok ...201425120343
genetic structure of wild boar (sus scrofa) populations from east asia based on microsatellite loci analyses.wild boar, sus scrofa, is an extant wild ancestor of the domestic pig as an agro-economically important mammal. wild boar has a worldwide distribution with its geographic origin in southeast asia, but genetic diversity and genetic structure of wild boar in east asia are poorly understood. to characterize the pattern and amount of genetic variation and population structure of wild boar in east asia, we genotyped and analyzed microsatellite loci for a total of 238 wild boar specimens from ten loca ...201425034725
genomic analysis reveals selection for asian genes in european pigs following human-mediated introgression.the independent domestication of local wild boar populations in asia and europe about 10,000 years ago led to distinct european and asian pig breeds, each with very different phenotypic characteristics. during the industrial revolution, chinese breeds were imported to europe to improve commercial traits in european breeds. here we demonstrate the presence of introgressed asian haplotypes in european domestic pigs and selection signatures on some loci in these regions, using whole genome sequence ...201425025832
stereological estimation of total cell numbers in the human cerebral and cerebellar cortex.our knowledge of the relationship between brain structure and cognitive function is still limited. human brains and individual cortical areas vary considerably in size and shape. studies of brain cell numbers have historically been based on biased methods, which did not always result in correct estimates and were often very time-consuming. within the last 20-30 years, it has become possible to rely on more advanced and unbiased methods. these methods have provided us with information about fetal ...201425076882

a novel strain of porcine adenovirus detected in urinary bladder urothelial cell culture.contamination of cell cultures is the most common problem encountered in cell culture laboratories. besides the secondary cell contaminations often occurring in the cell laboratories, the contaminations originating from donor animal or human tissue are equally as common, but usually harder to recognize and as such require special attention. the present study describes the detection of porcine adenovirus (padv), strain padv-svn1 in cultures of normal porcine urothelial (npu) cells isolated from u ...201424960273
targeting the ion channel kv1.3 with scorpion venom peptides engineered for potency, selectivity, and half-life.ion channels are an attractive class of drug targets, but progress in developing inhibitors for therapeutic use has been limited largely due to challenges in identifying subtype selective small molecules. animal venoms provide an alternative source of ion channel modulators, and the venoms of several species, such as scorpions, spiders and snails, are known to be rich sources of ion channel modulating peptides. importantly, these peptides often bind to hyper-variable extracellular loops, creatin ...201424939846
untangling the hybrid nature of modern pig genomes: a mosaic derived from biogeographically distinct and highly divergent sus scrofa populations.the merging of populations after an extended period of isolation and divergence is a common phenomenon, in natural settings as well as due to human interference. individuals with such hybrid origins contain genomes that essentially form a mosaic of different histories and demographies. pigs are an excellent model species to study hybridization because european and asian wild boars diverged ~1.2 mya, and pigs were domesticated independently in europe and asia. during the industrial revolution in ...201424863459
meiotic recombination analyses of individual chromosomes in male domestic pigs (sus scrofa domestica).for the first time in the domestic pig, meiotic recombination along the 18 porcine autosomes was directly studied by immunolocalization of mlh1 protein. in total, 7,848 synaptonemal complexes from 436 spermatocytes were analyzed, and 13,969 recombination sites were mapped. individual chromosomes for 113 of the 436 cells (representing 2,034 synaptonemal complexes) were identified by immunostaining and fluorescence in situ hybridization (fish). the average total length of autosomal synaptonemal co ...201424919066
genome-wide identification of long intergenic noncoding rna genes and their potential association with domestication in pigs.thousands of long intergenic noncoding rnas (lincrnas) have been identified in the human and mouse genomes, some of which play important roles in fundamental biological processes. the pig is an important domesticated animal, however, pig lincrnas remain poorly characterized and it is unknown if they were involved in the domestication of the pig. here, we used available rna-seq resources derived from 93 samples and expressed sequence tag data sets, and identified 6,621 lincrna transcripts from 4, ...201424891613
using biplanar fluoroscopy to guide radiopaque vascular injections: a new method for vascular imaging.studying vascular anatomy, especially in the context of relationships with hard tissues, is of great interest to biologists. vascular studies have provided significant insight into physiology, function, phylogenetic relationships, and evolutionary patterns. injection of resin or latex into the vascular system has been a standard technique for decades. there has been a recent surge in popularity of more modern methods, especially radiopaque latex vascular injection followed by ct scanning and dig ...201424835249
repeated evolution of chimeric fusion genes in the β-globin gene family of laurasiatherian mammals.the evolutionary fate of chimeric fusion genes may be strongly influenced by their recombinational mode of origin and the nature of functional divergence between the parental genes. in the β-globin gene family of placental mammals, the two postnatally expressed δ- and β-globin genes (hbd and hbb, respectively) have a propensity for recombinational exchange via gene conversion and unequal crossing-over. in the latter case, there are good reasons to expect differences in retention rates for the re ...201424814285
