Effectiveness of Field Simulation Approach for Problem-Based Learning That Incorporates the One Health Concept.

One Health problem-based learning (PBL) is known as an effective method in teaching zoonotic diseases. However, the classic classroom setting limits real-life exposure for students. Simulation-based learning may improve the learning experience without exposing the students to unnecessary risks.

Synovial fluid proteome profile of surgical versus chemical induced osteoarthritis in rabbits.

Background: Animal models are significant for understanding human osteoarthritis (OA). This study compared the synovial fluid proteomics changes in surgical and chemical induced OA models.

Methods: Thirty rabbits either had anterior cruciate ligament transection (ACLT) procedure or injected intra-articularly with monosodium iodoacetate (MIA, 8 mg) into the right knee.

In vitro evidence consistent with an interaction between wild-type and mutant SOD1 protein associated with canine degenerative myelopathy.

Canine degenerative myelopathy (DM) is a progressive neurological disorder that may be considered to be a large animal model for specific forms of the fatal human disease, familial amyotrophic lateral sclerosis (fALS). DM is associated with a c118G>A mutation of the superoxide dismutase 1 (Sod1) gene, and a significant proportion of cases are inherited in an autosomal recessive manner in contrast to the largely, but not exclusively, dominant mode of inheritance in fALS. The consensus view is that these Sod1/SOD1 mutations result in a toxic gain of function but the mechanisms remain unclear.

The chaperone protein clusterin may serve as a cerebrospinal fluid biomarker for chronic spinal cord disorders in the dog.

Chronic spinal cord dysfunction occurs in dogs as a consequence of diverse aetiologies, including long-standing spinal cord compression and insidious neurodegenerative conditions. One such neurodegenerative condition is canine degenerative myelopathy (DM), which clinically is a challenge to differentiate from other chronic spinal cord conditions. Although the clinical diagnosis of DM can be strengthened by the identification of the Sod1 mutations that are observed in affected dogs, genetic analysis alone is insufficient to provide a definitive diagnosis.

A protocol for the management of canine cerebrospinal fluid for the proteomic assessment of putative biomarkers.

Cerebrospinal fluid (CSF) is a potential source for disease-specific biomarkers that may assist in the staging and determining the prognosis of neurodegenerative conditions in animals. However, the validity of such putative biomarkers may be influenced by pre-analytical variables, including the procedures adopted to collect and store the CSF. This study assessed the effect of three handling practices on the stability of a panel of CSF proteins: clusterin (also known as apolipoprotein J), haptoglobin, cystatin C, and transthyretin (TTR).
