| genetic typing of recent classical swine fever virus isolates from croatia. | during a period of 5 years (1997-2001) several outbreaks of classical swine fever (csf) were recorded in croatia. for genetic typing, fragments of 150 nucleotides within the 5'-non-translated region (5'-ntr) and 190 nucleotides within the e2 glycoprotein coding gene of nine field isolates that were derived from domestic pigs and wild boars were used. for better epizootiological understanding, isolates from other european countries were included in the study. the results show that the isolates be ... | 2003 | 14516705 |
| increasing esophageal length: a comparison of laparoscopic versus transthoracic esophageal mobilization with and without vagal trunk division in pigs. | new laparoscopic techniques allow both mediastinal mobilization and performance of a collis gastroplasty when necessary, and the utility of a transthoracic approach is questioned. the aim of this study was to compare the increase in esophageal length achievable with laparoscopic and transthoracic esophageal mobilization in pigs, and to assess the impact of vagal trunk division on esophageal length. | 2003 | 14522324 |
| role of birds in transmission of classical swine fever virus. | active transmission of classical swine fever virus (csfv) was studied in six birds (five ravens, one hooded crow) and two laying hens. cloacal swabs, blood and organs of birds and hens as well as blood and organ samples of pigs which had been fed with faeces derived from csfv infected birds or which had come in contact with faeces of infected hens were negative for csfv. none of the animals seroconverted during the study. this result demonstrates that active virus transmission by these animals i ... | 2003 | 14535936 |
| genotyping of clostridium perfringens isolated from domestic and exotic ruminants and swine. | clostridium perfringens types a, b, c, d and e are known to cause severe enteritis/enterotoxaemia and diseases (especially caused by type a) belonging to the gas oedema complex in many species. samples from the small intestine as well as faeces of domestic and exotic animals suffering from enterotoxaemic signs or having died within days after first occurance of toxaemia were submitted for typing c. perfringens toxovars by multiplex pcr. the following species have been investigated: domestic shee ... | 2003 | 14535937 |
| influence of radiographic contrast media on myocardial tissue oxygen tension: nacl-controlled, randomised, comparative study of iohexol versus iopromide in an animal model. | it was tested whether a bolus injection of 10 ml radiographic contrast medium (iopromide vs. iohexol), compared to a 10 ml nacl bolus and administered into the left anterior descending artery (lad) of farm pigs, influenced the tissue po2 in the territory of this artery. the radiographic contrast media and the nacl bolus were given in randomised order. the mean po2 lad fell from initially 40.3+/-10.9 mmhg to a minimal value of 22.5+/-8.9 mmhg 241+/-44 sec after injecting the iopromide bolus, with ... | 2003 | 14561904 |
| spinal blood flow in 24-hour megadose glucocorticoid treatment in awake pigs. | because of the controversy regarding the benefits of 24-hour administration of methylprednisolone in patients with spinal cord injury (sci), it is important to investigate its mechanism of action and side effects. this study was conducted to determine if high-dose methylprednisolone modulates neural and vertebral blood flow in an awake large-sized animal model without sci. | 2003 | 14563146 |
| potential sites of virus latency associated with indigenous pseudorabies viruses in feral swine. | free-ranging feral swine (sus scrofa) are known to be present in at least 32 states of the usa and are continuously expanding their range. infection with pseudorabies virus (prv) occurs in feral swine and the primary route of transmission in free-living conditions seems to be venereal. between 1995 and 1999, naturally infected feral swine and experimentally infected hybrid progeny of feral and domestic swine, were kept in isolation and evaluated for occurrence of latent prv indigenous to feral s ... | 2003 | 14567217 |

| assessment of subacute inflammatory and proliferative response to coronary stenting in a porcine model by local gene expression studies and histomorphometry. | the aim of the study was to analyse inflammatory and proliferative response early after coronary stenting by angiography, histomorphometry and local gene expression analysis using quantitative rt-pcr. therefore, eight german domestic pigs underwent stenting of the left coronary artery. selective coronary angiography was performed after 14 days. explanted coronary arteries were examined histomorphometrically after methacrylate-embedding. snap-frozen samples were examined for local gene expression ... | 2004 | 14615159 |
| experimental infection of pregnant gilts with swine hepatitis e virus. | to determine the effect of swine hepatitis e virus (hev) infection on pregnant gilts, their fetuses, and offspring, 12 gilts were intravenously inoculated with swine hev. six gilts, who were not inoculated, served as controls. all inoculated gilts became actively infected and shed hev in feces, but vertical transmission was not detected in the fetuses. there was no evidence of clinical disease in the gilts or their offspring. mild multifocal lymphohistiocytic hepatitis was observed in 4 of 12 in ... | 2003 | 14620868 |
| evidence favoring the use of an alpha2-selective vasopressor agent for cardiopulmonary resuscitation. | both alpha1- and beta-adrenergic agonists increase the severity of global myocardial ischemic injury. we hypothesized that combined beta- and alpha1-adrenergic blockade would improve initial resuscitation and postresuscitation myocardial and neurological functions. we further hypothesized that the resulting alpha2-actions of relatively brief duration would favor improved functions compared with the more prolonged effect of nonadrenergic vasopressin. | 2003 | 14623815 |
| brain metabolism during cardiopulmonary resuscitation assessed with microdialysis. | microdialysis is an established tool to analyse tissue biochemistry, but the value of this technique to monitor cardiopulmonary resuscitation (cpr) effects on cerebral metabolism is unknown. the purpose of this study was to assess the effects of active-compression-decompression (acd) cpr in combination with an inspiratory threshold valve (itv) (=experimental cpr) vs. standard cpr on cerebral metabolism measured with microdialysis. | 2003 | 14625117 |
| immediate defibrillation versus interventions first in a swine model of prolonged ventricular fibrillation. | we compared time-dependent rescue shock success when delivered immediately, to defibrillation preceded by 3 min of cpr, with and without high dose epinephrine (hde) in a swine model of prolonged ventricular fibrillation (vf). our hypotheses were that pretreatment with cpr and hde would produce higher rates of successful first-shock defibrillation and would prevent decay of the vf waveform, as measured by the scaling exponent (sce), when compared to immediate defibrillation. we also sought to det ... | 2003 | 14625118 |
| epidemiology of mycobacterium bovis infections of pigs and wild boars using a molecular approach. | a molecular epidemiological approach was applied to establishing a possible role for the wild boar as a natural reservoir of mycobacterium bovis in sierra de villuercas, western spain; an area free of farmed cattle and wild deer populations. spoligo and vntr typing were used over a three year period to study the epidemiological relationship between the occurrence of bovine tuberculosis (tb) in extensively bred iberian pigs and indigenous wild boar. the 37 sampled wild boar showed different degre ... | 2003 | 14637044 |
| gene structure of pig sterol 12alpha-hydroxylase (cyp8b1) and expression in fetal liver: comparison with expression of taurochenodeoxycholic acid 6alpha-hydroxylase (cyp4a21). | cholic acid is the major trihydroxy bile acid formed in most mammals. the domestic pig (sus scrofa) is an exception. the bile of adult pig is devoid of cholic acid whereas hyocholic acid is found in amounts equal to that of cholic acid in humans. the pathway leading to formation of hyocholic acid is believed to be species-specific and to have evolved in the pig to compensate for a nonexistent or deficient cholic acid biosynthesis. however, a high level of cholic acid has recently been found in t ... | 2003 | 14643796 |
| [case report: porcine circovirus type 2 infection in an european wild boar (sus scrofa) in the state of brandenburg, germany]. | this case represents the first case of porcine circovirus type 2 (pcv-2)--infection in a free living european wild boar associated with morphological lesions, which are regarded as characteristic for postweaning multisystemic wasting syndrome (pmws) in domestic pigs. the animal, an approximately 10 month old male, was found dead in a rural area within the state of brandenburg, germany. the closest commercial pig farm is located in 3 km distance from the spot where the carcass was found. at necro ... | 2003 | 14650740 |

| efficacy of ultrasonic tissue dissector and tissue glue for laparoscopic partial nephrectomy in a porcine model. | the purpose of this study was to evaluate the efficacy and long-term tissue effects of ultrasonic dissector and cyanoacrylate glue during laparoscopic partial nephrectomy in a porcine model. nine domestic pigs underwent laparoscopic left lower pole partial nephrectomy without vascular control. an ultrasonic tissue dissector was used to assist in the parenchymal incision, and the raw surfaces of the kidneys, including the exposed urinary system, were sealed with cyanoacrylate glue. no internal st ... | 2003 | 14717525 |
| effects of statins on myocardial and coronary artery response to ischemia-reperfusion. | this study tested the hypotheses that (i) lipophilic statins (atorvastatin and simvastatin) impair ventricular recovery from myocardial ischemia-reperfusion, owing to their greater myocyte permeability, compared with a hydrophilic statin (pravastatin), and (ii) statins enhance endothelium-dependent vasodilation of isolated coronary arteries from the ischemic region. farm pigs consumed chow supplemented with atorvastatin (2.5 mg.kg(-1).d(-1); n=6), pravastatin (10 (n=3) or 20 (n=2) mg.kg(-1).d(-1 ... | 2003 | 14719042 |
| betaine improves growth, but does not induce whole body or hepatic palmitate oxidation in swine (sus scrofa domestica). | dietary betaine may reduce carcass fat in growing pigs. we explored the effects of betaine on short-term growth and in vivo and in vitro fatty acid oxidation. pigs were housed in metabolism crates and fed diets containing either 0% (control), 0.125% or 0.5% betaine at 80% of ad libitum energy intake. fatty acid oxidation was measured during intravenous infusions of 1-(13)c-palmitate and in hepatocytes incubated in the presence or absence of betaine and carnitine. co2 and palmitate isotopic enric ... | 2004 | 14720598 |
| functional and phylogenetic analyses of a melanocortin-4 receptor mutation in domestic pigs. | the melanocortin-4 receptor (mc4r), a g protein-coupled seven-transmembrane receptor, which is expressed in the brain, plays an important role in the control of mammalian energy homeostasis. a missense mutation (asp298asn) was identified in the porcine mc4r gene, which is associated with growth and food intake traits. the asn298 mutation occurs within a highly conserved motif, npliy, of all members of g protein-coupled receptors; whereas, asp298 is conserved in all five melanocortin receptor sub ... | 2004 | 14732454 |
| pressure-related hemodynamic effects of co2 pneumoperitoneum in a model of acute cardiac failure. | the adverse effects related to co2 pneumoperitoneum (pp) have been well documented. although these effects in the state of cardiac failure have not been investigated, it appears to be common current clinical practice to use low-pressure pp in this clinical setting, assuming it to be safer. | 2003 | 14733695 |
| a comparison of laparoscopic bipolar vessel sealing devices in the hemostasis of small-, medium-, and large-sized arteries. | the development of new energy sources for hemostasis has facilitated advanced laparoscopic procedures. few studies, however, have documented the strength of the vessels sealed or the extent of surrounding lateral thermal injury, two important factors in maintaining hemostasis while preventing injury to surrounding structures. this study compared the burst pressure and extent of thermal injury of vessels sealed with the 5-mm laparoscopic plasmakinetics trade mark sealer (pk) (gyrus medical, maple ... | 2003 | 14733701 |
| experimental disc degeneration due to endplate injury. | the aim of this study was to create an experimental model of disc degeneration that closely mimicked human disc degeneration. in six domestic pigs, an l4 cranial endplate perforation into the nucleus pulposus was made. three months postoperatively, compressive testing was performed on the l2-l4 motion segments, and intradiscal pressure was measured in the intervening discs. histochemical and morphologic examinations were made on the excised degenerated and adjacent discs. a significant reduction ... | 2004 | 14734978 |
| bipolar radiofrequency ablation of the kidney: comparison with monopolar radiofrequency ablation. | we report initial ex vivo and in vivo studies using bipolar radiofrequency (rf) ablation of porcine kidneys. an internal ground electrode is positioned in the kidney opposite the rf electrode, resulting in ablation of all the intervening renal tissue. | 2003 | 14744366 |
| long-term retention of endoscopically placed hydrogel prostheses at the lower esophageal sphincter in pigs. | using flexible endoscopic methods, hydrogel prostheses can be safely placed, retained for long periods of time, and removed from the esophageal submucosa of pigs. this new technique may have future applications in the treatment of gastroesophageal reflux disease in selected situations. | 2004 | 14752644 |
| [trichinellosis outbreaks in spain (1990-2001)]. | trichinellosis is a helminth infection having a wide geographical distribution. it is acquired by ingestion of raw or undercooked meat infected with trichinella spp. the present work reviews the human trichinellosis outbreaks recorded in spain during 1990-2001, taking into account both the geographical distribution and source of the infection. | 2004 | 14756987 |
| how long can we preserve the pulmonary graft inside the nonheart-beating donor? | the use of lungs from nonheart-beating donors (nhbd) might significantly alleviate the organ shortage. extending the preharvest interval in nhbd would facilitate distant organ retrieval. we hypothesized that prolonged topical cooling inside nhbd after 60 minutes of initial warm ischemia would not affect the pulmonary graft. | 2004 | 14759412 |
| uptake of 111in-z2d3 on spect imaging in a swine model of coronary stent restenosis correlated with cell proliferation. | small targets such as cell proliferation in the coronary arteries may potentially be detected with single-photon imaging using high-radiotracer-specific activity. we hypothesized that an antibody linked to polymers to increase specific radioactivity can be visualized on spect images and that counts in the target will correlate with the strength of the biologic signal. | 2004 | 14960651 |
| do domestic pigs in controlled environments contrafreeload? | many experiments report that animals will work (lever press) for food in the presence of freely available identical food. this phenomenon has attracted the attention of applied ethologists because it seems to prove that animals have a need to express appetitive behavior. if this is the case, then it has implications for the provision of environmental enrichment for animals in captivity. in this experiment, we maintained 6 pigs in closed economy environments for three 120-hr choice periods in whi ... | 2003 | 14965785 |
| adenoviral catheter-mediated intramyocardial gene transfer using the mature form of vascular endothelial growth factor-d induces transmural angiogenesis in porcine heart. | it is unclear what is the most efficient vector and growth factor for induction of therapeutic vascular growth in the heart. furthermore, the histological nature of angiogenesis and potential side effects caused by different vascular endothelial growth factors (vegfs) in myocardium have not been documented. | 2004 | 14967735 |
