The relationship between PcR-restriction fragment length polymorphism in RNASE1 (296 A/G), ANG (149 G/T) and RNASE6 (389 C/T) genes and the values of haematological and biochemical blood indices was analysed in crossbred suckling piglets (n = 473), aged 21 ± 3 days (younger, n = 274) and 35 ± 3 days (older, n = 199), descending from Polish Large White × Polish Landrace sows and Duroc × Pietrain boars. The observed distribution of all genotypes was consistent with the Hardy-Weinberg equilibrium. Anaemia was more common in younger piglets with RNASE1 GA genotype but in the blood of older GA piglets a higher count and percentage of granulocytes were noted. This could be related to the destruction of erythrocytes in younger piglets and enhanced host defence in older ones. ANG gene polymorphism was associated with the severity of iron deficiency in younger piglets. This is supposed to be linked with the different ability to protect immune cells against suppression and degradation during iron deficiency. in older piglets, this mutation differentiated the reactivity of the immune system. Varying levels of iron status and red blood cell indices in RNASE6 genotypes presumably resulted from the coupling of genes involved in iron metabolism and expressed in an age-dependent manner.

Abstract

Purpose

An isolated perfused pig heart model has recently been proposed for the development of novel methods in standard clinical magnetic resonance (MR) scanners. The original set-up required the electrical system to be within the safe part of the MR-room, which introduced significant background noise. The purpose of the current work was to refine the system to overcome this limitation so that all electrical parts are completely outside the scanner room.

Methods

Four pig hearts were explanted under terminal anaesthesia from large white cross landrace pigs. All hearts underwent cardiovascular magnetic resonance (CMR) scanning in the MR part of a novel combined 3T MR and x-ray fluoroscopy (XMR) suite. CMR scanning included real-time k-t SENSE functional imaging, k-t SENSE accelerated perfusion imaging and late gadolinium enhancement imaging. Interference with image quality was assessed by spurious echo imaging and compared to noise levels acquired while operating the electrical parts within the scanner room.

Results

Imaging was performed successfully in all hearts. The system proved suitable for isolated heart perfusion in a novel 3T XMR suite. No significant additional noise was introduced into the scanner room by our set-up.

Conclusions

We have substantially improved a previous version of an isolated perfused pig heart model and made it applicable for MR imaging in a state of the art clinical 3T XMR imaging suite. The use of this system should aid novel CMR sequence development and translation into clinical practice.

A two-way selection procedure was performed on a Landrace pig line. First the cardiac output (CO) values (6.89 ± 1.27 L/min) were estimated by ECG-gated magnetic resonance imaging (MRI) to quantify the heart performance of the boars (n = 30), then total body skeletal muscle volume (MVTB; 48.7 ± 5.17 dm 3 ) was determined applying spiral computerised tomography (CT). The relative cardiac output value (RCO) was developed, expressing the relationship between CO and MVTB. Four superior [RCO value below 6.7 dm 3 / (L * min −1 )] and one minus variant [(8.97 dm 3 / (L * min −1 )] boars were taken into breeding. The best fifteen percentage of the first generation males (n = 30) was characterised according to their RCO values. Significant difference was found between the developed performance measure of the progenies of minus and plus variant boars [8.2 ± 0.65 and 5.63 ± 0.70 dm 3 / (L * min −1 ), n = 7 and 23], respectively. Comparing the existing five progeny groups, all of the ‘HP+’ groups differed significantly from the ‘HP-’ one, where the largest heart performance contrast found was 3.2 dm 3 / (L * min −1 ). Based upon the results, the selection is being continued on a larger population.
