Esophagotomy in a domestic fowl: a rare case report.

Background: Foreign body in esophagus in birds is rarely reported in literature. Most common site of foreign body in birds is proventriculus and ventriculus. The purpose of this study is to discuss the diagnosis of a large sharp foreign body in the distal third of the neck by plain radiography and its retrieval through esophagotomy and subsequent survival of the fowl.

Isolation, proliferation, characterization and in vivo osteogenic potential of bone-marrow derived mesenchymal stem cells (rBMSC) in rabbit model.

Information on isolation, characterization of rabbit MSC and its evaluation in critical bone defect (CSD) is scarcely available. Here, we attempted to isolate, proliferate, differentiate, characterize and evaluate the in vivo osteogenic potential of bone marrow derived mesenchymal stem cells (BMSCs) collected from New Zealand White rabbits. They were isolated and proliferated in antibiotic supplemented DMEM (Dulbecco’s Modified Eagle’s media).

Mesenchymal stem cells-seeded bio-ceramic construct for bone regeneration in large critical-size bone defect in rabbit.

Bone marrow derived mesenchymal stem cells (BMSC) represent an attractive cell population for tissue engineering purpose. The objective of this study was to determine whether the addition of recombinant human bone morphogenetic protein (rhBMP-2) and insulin-like growth factor (IGF-1) to a silica-coated calcium hydroxyapatite (HASi) - rabbit bone marrow derived mesenchymal stem cell (rBMSC) construct promoted bone healing in a large segmental bone defect beyond standard critical -size radial defects (15mm) in rabbits. An extensively large 30mm long radial ostectomy was performed unilaterally in thirty rabbits divided equally in five groups.

A Novel Method to Generate Amplitude-Frequency Modulated Vibrotactile Stimulation.

The natural interaction of humans with their environment involves the harmonious coordination of the body, for which multi-modal feedback including vision, proprioception, and tactile perception is essential. Most human-machine interfaces, however, rely on the visual feedback only, and this can lead to considerable cognitive burden. Additional haptic feedback can increase the intuitiveness of the man-machine interaction.

Building an internal model of a myoelectric prosthesis via closed-loop control for consistent and routine grasping.

Prosthesis users usually agree that myoelectric prostheses should be equipped with somatosensory feedback. However, the exact role of feedback and potential benefits are still elusive. The current study investigates the nature of human control processes within a specific context of routine grasping.
