A comprehensive bank of flipped classrooms was developed to help students prepare for animal handling and clinical skills practical classes. Flipped classroom is a type of blended learning. In the context of clinical skills, it is designed to provide students with online learning resources prior to attendance at practical classes.

In rodents, immune responses to minor histocompatibility antigens are the most important drivers of corneal graft rejection. However, this has not been confirmed in humans or in a large animal model and the genetic loci are poorly characterised, even in mice. The gene sequence data now available for a range of relevant species permits the use of genome-wide association (GWA) techniques to identify minor antigens associated with transplant rejection.

Purpose: The purpose of our study is to develop a pre-clinical model of corneal graft rejection in the semi-inbred NIH minipig as a model of human rejection.

Methods: NIH minipigs received corneal allografts with MHC and minor mismatches, or minor mismatches alone. Clinical rejection was monitored, and major subsets of leukocytes and ingress of vessels were quantified post-mortem by automated digital methods.

Article Synopsis
  • Early-life colonization by intestinal microbiota shapes the developing immune system, influencing future immune responses.
  • Research using neonatal animals, particularly inbred piglets, helps uncover how microbiota affects immune development and informs potential therapies.
  • The study finds that colonization with specific microbiota leads to the growth of certain immune cells, particularly SIRPα(+) antigen-presenting cells, which play a key role in early mucosal immunity without affecting other immune cell types.

Current techniques for reinnervation of the larynx following recurrent laryngeal nerve (RLN) injury are limited by synkinesis, which prevents functional recovery. Treatment with neurotrophins (NT) may enhance nerve regeneration and encourage more accurate reinnervation. This study presents the results of using the phrenic nerve transfer method, combined with NT-3 treatment, to selectively reinnervate the posterior cricoarytenoid (PCA) abductor muscle in a pig nerve injury model.
