| characterization of the african swine fever virus decapping enzyme during infection. | african swine fever virus (asfv) infection is characterized by a progressive decrease in cellular protein synthesis with a concomitant increase in viral protein synthesis, though the mechanism by which the virus achieves this is still unknown. decrease of cellular mrna is observed during asfv infection, suggesting that inhibition of cellular proteins is due to an active mrna degradation process. asfv carries a gene (ba71v d250r/malawi g5r) that encodes a decapping protein (asfv-dp) that has a nu ... | 2017 | 29021398 |
| why is african swine fever still present in sardinia? | african swine fever (asf) is an infectious disease of swine that has been present in sardinia since 1978. soon after introduction of the disease, several control and eradication programmes were established with limited success. some researchers attributed the persistence of the disease in central and eastern areas to certain socio-economic factors, the existence of some local and traditional farming practices (i.e., unregistered free-ranging pigs known as brado animals) and the high density of w ... | 2017 | 29027378 |
| biocompatibility and osseointegration of titanium implants with a silver-doped polysiloxane coating: an in vivo pig model. | to test the antimicrobial properties, surface topography, reaction of surrounding tissue (biocompatibility), and osseointegration of ultrathin implant surfaces containing polysiloxane and nanoscaled silver particles. | 2017 | 29028852 |
| simultaneous profiles of sulfonated androgens, sulfonated estrogens and sulfonated progestogens in postpubertal boars (sus scrofa domestica) measured by lc-ms/ms. | sulfonated steroids (s-st) have been usually regarded as inactive metabolites but are progressively considered as precursors for the intra-tissue formation of bioactive steroids. moreover, independent effects without preceding removal of the sulfate group have been observed. we use the porcine testicular-epididymal compartment as a model to investigate the still largely unknown s-st physiology as the boar exhibits an intriguingly broad s-st spectrum predominantly originating from the testis. the ... | 2017 | 29030154 |
| population admixture in chinese and european sus scrofa. | relationships between different populations were investigated using porcine 60 k data from 1,135 domestic pigs and wild boars across europe and china. the results indicate that most european breeds have been introgressed with chinese ancestry, but the extent of introgression varies considerably among breeds. moreover, the main source of this introgression is pigs from south china, closely related to bamaxiang and dongshan pigs. contributions from east and central chinese pig breeds are also dete ... | 2017 | 29030577 |
| reliability of transcardiopulmonary thermodilution cardiac output measurement in experimental aortic valve insufficiency. | monitoring cardiac output (co) is important to optimize hemodynamic function in critically ill patients. the prevalence of aortic valve insufficiency (ai) is rising in the aging population. however, reliability of co monitoring techniques in ai is unknown. the aim of this study was to investigate the impact of ai on accuracy, precision, and trending ability of transcardiopulmonary thermodilution-derived cotcptd in comparison with pulmonary artery catheter thermodilution copac. | 2017 | 29049339 |
| production, performance, slaughter characteristics, and meat quality of ziwuling wild crossbred pigs. | wild boars, because of their large size and ability to survive adverse conditions, are usually used to cross with domestic breeds to improve the quality of domesticated pigs. this study aimed to investigate the growth performance, slaughter performance, and meat quality of ziwuling crossbred pigs. crossbred pigs in four groups (n = 8 per group, 4 boars and 4 sows, all aged 100 days), f1[wild × b (bamei)], f1 × b, f1 × y (yorkshire), and f1 × f1, were selected at a commercial pig farm. growth per ... | 2018 | 29064063 |
| genome-wide analysis of structural variants reveals genetic differences in chinese pigs. | pigs have experienced long-term selections, resulting in dramatic phenotypic changes. structural variants (svs) are reported to exert extensive impacts on phenotypic changes. we built a high resolution and informative sv map based on high-depth sequencing data from 66 chinese domestic and wild pigs. we inferred the sv formation mechanisms in the pig genome and used svs as materials to perform a population-level analysis. we detected the selection signals on chromosome x for northern chinese dome ... | 2017 | 29065176 |
| tracing the breeding farm of domesticated pig using feature selection (sus scrofa). | increasing food safety demands in the animal product market have created a need for a system to trace the food distribution process, from the manufacturer to the retailer, and genetic traceability is an effective method to trace the origin of animal products. in this study, we successfully achieved the farm tracing of 6,018 multi-breed pigs, using single nucleotide polymorphism (snp) markers strictly selected through least absolute shrinkage and selection operator (lasso) feature selection. | 2017 | 29073733 |
| utilization of mri for cerebral white matter injury in a hypobaric swine model-validation of technique. | repetitive hypobaric exposure in humans induces subcortical white matter change, observable on magnetic resonance imaging (mri) and associated with cognitive impairment. similar findings occur in traumatic brain injury (tbi). we are developing a swine mri-driven model to understand the pathophysiology and to develop treatment interventions. | 2017 | 29087921 |
| metabolic syndrome alters expression of insulin signaling-related genes in swine mesenchymal stem cells. | metabolic syndrome (mets) is associated with insulin resistance (ir) and impaired glucose metabolism in muscle, fat, and other cells, and may induce inflammation and vascular remodeling. endogenous reparative systems, including adipose tissue-derived mesenchymal stem/stromal cells (msc), are responsible for repair of damaged tissue. msc have also been proposed as an exogenous therapeutic intervention in patients with cardiovascular and chronic kidney disease (ckd). the feasibility of using autol ... | 2018 | 29101070 |
| preclinical animal models for temporomandibular joint tissue engineering. | there is a paucity of in vivo studies that investigate the safety and efficacy of temporomandibular joint (tmj) tissue regeneration approaches, in part due to the lack of established animal models. review of disease models for study of tmj is presented herein with an attempt to identify relevant preclinical animal models for tmj tissue engineering, with emphasis on the disc and condyle. although degenerative joint disease models have been mainly performed on mice, rats, and rabbits, preclinical ... | 2018 | 29121815 |

| outbreaks of neuroinvasive astrovirus associated with encephalomyelitis, weakness, and paralysis among weaned pigs, hungary. | a large, highly prolific swine farm in hungary had a 2-year history of neurologic disease among newly weaned (25- to 35-day-old) pigs, with clinical signs of posterior paraplegia and a high mortality rate. affected pigs that were necropsied had encephalomyelitis and neural necrosis. porcine astrovirus type 3 was identified by reverse transcription pcr and in situ hybridization in brain and spinal cord samples in 6 animals from this farm. among tissues tested by quantitative rt-pcr, the highest v ... | 2017 | 29148391 |
| characterization of domestic pig spermatogenesis using spermatogonial stem cell markers in the early months of life. | in pigs, spermatogonial stem cells (sscs), which include gonocytes and undifferentiated spermatogonia, are classically defined as being present till up to 2 months of life. however, knowledge about this transition from gonocytes to undifferentiated spermatogonia in pigs is limited. in this study, we characterized pig sscs in neonatal (n = 6), one-month-old (1-mo-old, n = 6), two-month-old (2-mo-old, n = 6), and adult testes (n = 6) anatomically, histologically, and immunohistologically. anatomic ... | 2018 | 29156418 |
| serological evidence of hepatitis e virus infection in zoo animals and identification of a rodent-borne strain in a syrian brown bear. | hepatitis e virus (hev) is the causative agent of hepatitis e, an emerging infectious disease of humans. hev infections have also been described in various animal species. whereas domestic pigs and wild boars are well-known animal reservoirs for hev, the knowledge on natural hev infection in zoo animals is scarce so far. here, we analysed 244 sera from 66 mammal species derived from three zoos in germany using a commercial double antigen sandwich elisa. hev-specific antibodies were detected in 1 ... | 2017 | 29173594 |
| behavioural lateralization in domestic pigs (sus scrofa)-variations between motor functions and individuals. | motor lateralization is hypothesized to depend on the complexity of the motor function, but it might at the same time reflect hemispheric dominance within an individual across motor functions. we investigated possible motor lateralization patterns in four motor functions of different complexity (snout use in a manipulative task, foot use in two-stepping tasks and tail curling) in the domestic pig, a tetrapod species relevant as farm animal but also as a model in human neuroscience. a significant ... | 2017 | 29191074 |
| compression sonography for non-invasive measurement of lower leg compartment pressure in an animal model. | compression ultrasound is a non-invasive technique allowing for qualitative visualization and quantitative measurements of mechanical tissue properties. in acute compartment syndrome (acs), cadaver studies have proven that the intra-compartmental pressure (icp) measured by compression sonography correlates with the icp measured invasively. this study aimed to evaluate compression sonography for compartment pressure measurements in an animal model. | 2017 | 29195681 |
| effects of intramuscularly administered enrofloxacin on the susceptibility of commensal intestinal escherichia coli in pigs (sus scrofa domestica). | in the european union, various fluoroquinolones are authorised for the treatment of food producing animals. each administration poses an increased risk of development and spread of antimicrobial resistance. the aim of this study was to investigate the impact of parenteral administration of enrofloxacin on the prevalence of enrofloxacin and ciprofloxacin susceptibilities in the commensal intestinal e. coli population. | 2017 | 29202759 |
| hepatitis e seroprevalence and genotyping in a cohort of wild boars in southern germany and eastern alsace. | in the last few years it has been realized that the hepatitis e virus (hev) is endemic in most industrialized countries and that it is a zoonotic disease. potential reservoirs for hev have been identified to be wild boars and deers, but hev has also been found in domestic pigs and other animals. due to the probable spread of the virus via contaminated food or contact to infected animals, hev antibodies are present in more than 16% of the german adult population and rates are increasing with age. ... | 2017 | 29214558 |
| comparison of continuous compression with regular ventilations versus 30:2 compressions-ventilations strategy during mechanical cardiopulmonary resuscitation in a porcine model of cardiac arrest. | a compression-ventilation (c:v) ratio of 30:2 is recommended for adult cardiopulmonary resuscitation (cpr) by the current american heart association (aha) guidelines. however, continuous chest compression (ccc) is an alternative strategy for cpr that minimizes interruption especially when an advanced airway exists. in this study, we investigated the effects of 30:2 mechanical cpr when compared with ccc in combination with regular ventilation in a porcine model. | 2017 | 29221300 |
| toxoplasma gondii seroprevalence in breeding pigs in estonia. | toxoplasma gondii is a widespread occurring parasite infecting warm-blooded animals, including pigs and humans. the aims of this study were to estimate the prevalence of anti-t. gondii antibodies and to evaluate risk factors for t. gondii seropositivity in breeding pigs raised in estonia. sera from 382 pigs were tested with a commercial direct agglutination test, using a cut-off titer of 40 for seropositivity, for the presence of anti-t. gondii immunoglobulin g antibodies. | 2017 | 29228997 |
| a nationwide serosurvey of hepatitis e virus antibodies in the general population of portugal. | evidence has shown that hepatitis e virus (hev) genotype 3 is autochthonous in industrialized countries due to zoonotic transmission through direct contact or consumption of raw or undercooked meat from domestic swine or wild boar. as there is lack of data on seroprevalence of hev in the general portuguese population, a wide survey was conducted as part of the hepecontrol project (60dt2), under eea grants funding. | 2017 | 29237007 |
| prevalence and risk factors of japanese encephalitis virus (jev) in livestock and companion animal in high-risk areas in malaysia. | japanese encephalitis (je) is vector-borne zoonotic disease which causes encephalitis in humans and horses. clinical signs for japanese encephalitis virus (jev) infection are not clearly evident in the majority of affected animals. in malaysia, information on the prevalence of jev infection has not been established. thus, a cross-sectional study was conducted during two periods, december 2015 to january 2016 and march to august in 2016, to determine the prevalence and risk factors in jev infecti ... | 2017 | 29243139 |
| questionnaire-based assessment of wild boar/domestic pig interactions and implications for disease risk management in corsica. | wild boars and domestic pigs belong to the same species (sus scrofa). when sympatric populations of wild boars, feral pigs, and domestic pigs share the same environment, interactions between domestic and wild suids (idws) are suspected to facilitate the spread and maintenance of several pig pathogens which can impact on public health and pig production. however, information on the nature and factors facilitating those idws are rarely described in the literature. in order to understand the occurr ... | 2017 | 29250528 |
| evaluation of protection induced by immunisation of domestic pigs with deletion mutant african swine fever virus beninδmgf by different doses and routes. | a live attenuated african swine fever virus (asfv) vaccine candidate, produced by deletion of several genes belonging to multi-gene families mgf360 and 505 from virulent benin 97/1 strain (beninδmgf), induces protection in pigs against parental virulent strain. in order to better define the safety and efficacy of this attenuated vaccine candidate and to understand protective mechanisms, we extended previous studies by intramuscular immunisation of pigs with the deletion mutant beninδmfg at diffe ... | 2018 | 29254837 |
| modulation of the main porcine enteric neuropeptides by a single low-dose of lipopolysaccharide (lps) salmonella enteritidis. | the present research was conducted to investigate the influence of a low, single dose of lps, which does not result in any clinical symptoms of intoxication on the expression of selected neuropeptides within the intestines of the domestic pig. | 2017 | 29255488 |
| inferring the evolution of the major histocompatibility complex of wild pigs and peccaries using hybridisation dna capture-based sequencing. | the major histocompatibility complex (mhc) is a key genomic model region for understanding the evolution of gene families and the co-evolution between host and pathogen. to date, mhc studies have mostly focused on species from major vertebrate lineages. the evolution of mhc classical (ia) and non-classical (ib) genes in pigs has attracted interest because of their antigen presentation roles as part of the adaptive immune system. the pig family suidae comprises over 18 extant species (mostly wild ... | 2017 | 29256177 |
| the silent spread of porcine bocavirus in croatian pigs: should we be concerned? | a survey was conducted to evaluate the presence and prevalence of porcine bocavirus (pbov) in croatian domestic pigs by means of pcr targeting the ns1 gene fragment of pbov. this study included testing of faecal samples collected from 10 small commercial farms and 11 small backyard holdings in croatia. the presence of pbov was confirmed by pcr in 24 out of 57 composite faecal samples from small commercial farms and in 12 out of 43 composite faecal samples from small backyard holdings. the pcr pr ... | 2017 | 29256289 |
| spontaneously arrested transmission of cysticercosis in a highly endemic village with a very low migration rate. | taenia soliumcysticercosis is difficult to eliminate without interventions or societal development. atahualpa is a rural ecuadorian village with documented low migration rate, where domestic pig raising is common and human cysticercosis is endemic. to assess neurocysticercosis (ncc) prevalence, 1,273 villagers aged ≥ 20 years underwent neuroimaging studies, which showed calcified lesions in 121 (9.5%) individuals, but no active disease. likewise, positive reactions, apparently nonspecific, were ... | 2017 | 29260655 |
| effects of autologous fat and ascs on swine hypertrophic burn scars: a multimodal quantitative analysis. | hypertrophic scar formation is unpredictable and poorly understood, afflicting both the pediatric and adult populations. treatment methods with conservative and invasive approaches have low rates of compliance and high rates of morbidity. the purpose of this study was to test a reproducible scar model and investigate a new technique of scar modification through the use of adipose- derived progenitor stromal cells (ascs). | 2017 | 29263956 |
| mitochondrial targeted peptides preserve mitochondrial organization and decrease reversible myocardial changes in early swine metabolic syndrome. | the mechanisms responsible for cardiac damage in the early stages of metabolic syndrome (mets) remain unknown. mitochondria are intimately associated with cellular myofibrils, with the cytoskeleton functioning as a linkage coordinator, and closely associated to the calcium release sites of the sarcoplasmic reticulum (sr). objective: we hypothesized that early mets is characterized by mitochondria-related myocardial damage, associated with altered cytoskeletal-mitochondria-sr interaction. methods ... | 2017 | 29267873 |

| intrarenal fat deposition does not interfere with the measurement of single-kidney perfusion in obese swine using multi-detector computed tomography. | altered vascular structure or function in several diseases may impair renal perfusion. multi-detector computed tomography (mdct) is a non-invasive tool to assess single-kidney perfusion and function based on dynamic changes in tissue attenuation during contrast media transit. however, changes in basal tissue attenuation might hamper these assessments, despite background subtraction. evaluation of iodine concentration using the dual-energy (dect) mdct mode allows excluding effects of basal values ... | 2018 | 29339048 |
| gastrointestinal protists and helminths of habituated agile mangabeys (cercocebus agilis) at bai hokou, central african republic. | infectious diseases including those caused by parasites can be a major threat to the conservation of endangered species. there is thus a great need for studies describing parasite infections of these species in the wild. here we present data on parasite diversity in an agile mangabey (cercocebus agilis) group in bai hokou, dzanga-sangha protected areas (dspa), central african republic. we coproscopically analyzed 140 mangabey fecal samples by concentration techniques (flotation and sedimentation ... | 2018 | 29350404 |
| genetic diversity, breed composition and admixture of kenyan domestic pigs. | the genetic diversity of african pigs, whether domestic or wild has not been widely studied and there is very limited published information available. available data suggests that african domestic pigs originate from different domestication centers as opposed to international commercial breeds. we evaluated two domestic pig populations in western kenya, in order to characterize the genetic diversity, breed composition and admixture of the pigs in an area known to be endemic for african swine fev ... | 2018 | 29357367 |
| viability and biocompatibility of an adhesive system for intrarenal embedding and endoscopic removal of small residual fragments in minimally-invasive stone treatment in an in vivo pig model. | to evaluate the viability and biocompatibility of a novel, patented bioadhesive system for intrarenal embedding and retrieval of residual fragments after endoscopic lithotripsy. complete stone clearance via active removal of residual fragments (rf) after intracorporeal laser lithotripsy may be time-consuming and fail in many cases. therefore, the novel adhesive has been developed and evaluated for the first time in an in vivo pig model in the present work. | 2018 | 29368229 |
| a serologic survey of pathogens in wild boar ( sus scrofa) in sweden. | the wild boar ( sus scrofa) population has increased markedly during the last three decades in sweden and in other parts of europe. this population growth may lead to increased contact between the wild boar and the domestic pig ( sus scrofa scrofa), increasing the risk of transmission of pathogens. the objective of our study was to estimate the seroprevalence of selective pathogens, known to be shared between wild boars and domestic pigs in europe, in three wild boar populations in sweden. in to ... | 2018 | 29377751 |
| immunisation of pigs by dna prime and recombinant vaccinia virus boost to identify and rank african swine fever virus immunogenic and protective proteins. | african swine fever virus (asfv) causes an acute haemorrhagic fever in domestic pigs with high socio-economic impact. no vaccine is available limiting options for control. although live attenuated asfv can induce up to one hundred percent protection against lethal challenge, little is known of the antigens which induce this protective response. to identify additional asfv immunogenic and potentially protective antigens we cloned 47 viral genes in individual plasmids for gene vaccination and in r ... | 2018 | 29386289 |
| efficacy and safety of sic-8000 (eleview®) for submucosal injection for endoscopic mucosal resection and endoscopic submucosal dissection in an in vivo porcine model. | submucosal injection is generally required for both endoscopic-mucosal resection (emr) and submucosal dissection (esd). sic-8000 (eleview™) is a new fda 510(k) cleared and ce marked liquid composition for submucosal injection, containing a biocompatible polymer as a cushioning agent. | 2017 | 29396133 |
| the development of an interactive computer-based training program for timely and humane on-farm pig euthanasia. | with extensive knowledge and training in the prevention, management, and treatment of disease conditions in animals, veterinarians play a critical role in ensuring good welfare on swine farms by training caretakers on the importance of timely euthanasia. to assist veterinarians and other industry professionals in training new and seasoned caretakers, an interactive computer-based training program was created. it consists of three modules, each containing five case studies, which cover three dist ... | 2018 | 29400634 |
| observational analysis on inflammatory reaction to talc pleurodesis: small and large animal model series review. | talc pleurodesis has been associated with pleuropulmonary damage, particularly long-term damage due to its inert nature. the present model series review aimed to assess the safety of this procedure by examining inflammatory stimulus, biocompatibility and tissue reaction following talc pleurodesis. talc slurry was performed in rabbits: 200 mg/kg checked at postoperative day 14 (five models), 200 mg/kg checked at postoperative day 28 (five models), 40 mg/kg, checked at postoperative day 14 (five m ... | 2018 | 29403549 |
| suitability of the porcine aortic model for transcatheter aortic root repair. | to treat aortic valve disease and concomitant root disease with transcatheter techniques, 'composite graft' implants are required. our goal was to assess the suitability of the porcine aortic root for transcatheter root repair tests. | 2018 | 29415164 |
| genetic variation analysis of pcv1 strains isolated from guangxi province of china in 2015. | porcine circovirus type 1 (pcv1) was discovered in 1974 as a contaminant of a porcine kidney (pk-15) cell line and was generally accepted to be nonpathogenic. but recently it was shown to cause lesions in experimentally infected pig fetuses. serological evidence and genetic studies suggested that pcv1 was widespread in domestic pigs. thus, the molecular epidemiology and genetic variation of pcv1 are still necessary to understand. | 2018 | 29415728 |
| voluntary locomotor activity promotes myogenic growth potential in domestic pigs. | self-determined physical activity is an essential behavioural need and can vary considerably between individuals of a given species. although locomotion is suggested as a prerequisite for adequate function of skeletal muscle, domestic pigs are usually reared under limited space allowance. the aim of our study was to investigate if a different voluntary locomotor activity leads to altered properties in the muscle structure, biochemistry and mrna expression of selected genes involved in myogenesis ... | 2018 | 29416067 |
| aujeszky's disease and hepatitis e viruses transmission between domestic pigs and wild boars in corsica: evaluating the importance of wild/domestic interactions and the efficacy of management measures. | wildlife species as reservoirs of infectious pathogens represent a serious constraint in the implementation of disease management strategies. in the mediterranean island of corsica, the dynamics of hepatitis e virus (hev) and aujeszky's disease virus (adv) are suspected to be influenced by interactions between wild and domestic pigs. to improve our understanding of these influences, we first compared the seroprevalences of both viruses in domestic pig populations from different locations with co ... | 2018 | 29417054 |
| identification of two novel foot-and-mouth disease virus cytotoxic t lymphocyte epitopes that can bind six sla-i proteins. | currently available vaccines from inactivated foot-and-mouth disease virus (fmdv) only protect animals by inducing neutralizing antibodies. a vaccine that contains cytotoxic t lymphocytes (ctl) epitopes to induce strong ctl responses might protect animals more effectively. herein, we used swine leukocyte antigen class i (slai) proteins derived from six different strains of domestic pigs to screen and identify shared fmdv ctl epitopes. four potential fmdv ctl epitopes (q01, q02, as3, and qa4) wer ... | 2018 | 29432828 |
| genomic sequence of a swine pasivirus type 1 strain identified in u.s. swine. | we report for the first time in the united states the identification of a swine pasivirus (spav) strain with a genomic sequence identity of less than 80% to other spavs reported in europe and china, using a next-generation sequencing (ngs) technique in sow tissues collected from an animal study conducted in 2001, suggesting virus circulation in domestic swine. | 2018 | 29439048 |
| the effect of three different surgical techniques for colon anastomosis on regional postoperative microperfusion: laser doppler flowmetry study in pigs. | the optimal surgical approach to reconnecting bowel ends safely after resection is of great importance. | 2018 | 29439318 |
| accurate depth of radiofrequency-induced lesions in renal sympathetic denervation based on a fine histological sectioning approach in a porcine model. | ablation lesion depth caused by radiofrequency-based renal denervation (rdn) was limited to <4 mm in previous animal studies, suggesting that radiofrequency-rdn cannot ablate a substantial percentage of renal sympathetic nerves. we aimed to define the true lesion depth achieved with radiofrequency-rdn using a fine sectioning method and to investigate biophysical parameters that could predict lesion depth. | 2018 | 29440276 |
| the zbed6-igf2 axis has a major effect on growth of skeletal muscle and internal organs in placental mammals. | a single nucleotide substitution in the third intron of insulin-like growth factor 2 (igf2) is associated with increased muscle mass and reduced subcutaneous fat in domestic pigs. this mutation disrupts the binding of the zbed6 transcription factor and leads to a threefold up-regulation ofigf2expression in pig skeletal muscle. here, we investigated the biological significance of zbed6-igf2interaction in the growth of placental mammals using two mouse models, zbed6 knock-out (zbed6-/-) andigf2kno ... | 2018 | 29440408 |
| hepatitis e virus infection of slaughtered healthy pigs in brazil. | hepatitis e virus (hev) is an emerging pathogen that can be transmitted through contaminated raw or undercooked meat derived from domestic pigs. hev infections have been documented among pig herds, pig products and environmental samples raising concern about the spread of the virus. hev genotypes 3 and 4 are considered zoonotic and have been linked to human cases. hev was detected in 51 of 335 bile samples (15.2%) from healthy pigs in minas gerais, brazil. phylogenetic analysis of partial sequen ... | 2018 | 29441690 |
| developmental regulation of the intestinal fgf19 system in domestic pigs. | fibroblast growth factor-19 (fgf19) is an emerging endocrine factor involved in the regulation of bile acid homeostasis and energy metabolism in rodents and humans. in pigs, however, the fgf19 system remains largely unexplored. this study was designed to investigate the developmental regulation of the fgf19 system in domestic pigs. samples of intestinal sections, liver, and plasma were collected from 24 pigs (n = 6) at four developmental stages (birth, pre-weaning, post-weaning, and adulthood). ... | 2018 | 29446652 |
