Abstract
This study aims to establish whether the use of biomaterials, particularly polydimethylsiloxane (PDMS), for surgical reconstruction of the esophagus with templates, Montgomery salivary tube, after radical oncology surgery for malignant neoplasia is an optimal choice for patients' safety and for optimal function preservation and organ rehabilitation. Structural analysis by Raman spectrometry and biomechanical properties with dynamic mechanical analysis are performed for fatigue strength and toughness, essential factors in durability of a prosthesis in the reconstruction practice of the esophagus. Nanocomposites with silicone elastomers and nanoparticles used in implantable devices and in reconstruction surgery present risks of infection and fatigue strength when required to perform a mechanical effort for long periods of time. This report takes into account the effect of silver (Ag) nanoparticles on the fatigue strength using polydimethylsiloxane (PDMS) matrix, representative for silicon elastomers used in implantable devices. PDMS with 5% (wt) Ag nanoparticles of 100-150 nm during mechanical fatigue testing at shear strength loses elasticity properties after 400 loading-unloading cycles and up to 15% shear strain. The fatigue strength, toughness, maximum shear strength, as well as clinical properties are key issues in designing Montgomery salivary tube and derivates with appropriate biomechanical behavior for each patient. Prosthesis design needs to indulge both clinical outcomes as well as design methods and research in the field of biomaterials.

Abstract
Swine pasivirus 1 (SPaV-1) was first detected in the feces of healthy pigs in France as a new species in family Picornaviridae. We investigated the presence, distribution, and genetic variability of this virus in 7 geographic areas with intensive pig breeding farms in eastern Romania. A total of 564 porcine specimens, including 82 fecal specimens and 482 pools of organs, were collected from healthy pigs in different stages of production from pathogen-free swine farming units. The virus was found in 6 of 7 areas investigated. Of the 564 samples analyzed, 218 were positive for SPaV-1, with the highest prevalence of the virus in organ homogenates (39% positive) followed by feces (37% positive). The highest susceptibility to infection was found in nurseries (50% positive in both the first and second months of feeding). Sequencing analysis of VP0 revealed 3 different Romanian sequences. The phylogenetic investigations suggest that the Romanian sequences cluster with other Pasivirus strains selected from the GenBank database, forming a separate clade from other Picornaviridae genera and defining the described Pasivirus.
