Immunophenotyping of progenitor cells from articular cartilage of New Zealand Rabbits (Oryctolagus cuniculus).

Mesenchymal stem cell (MSC) have immunomodulatory and anti-inflammatory effects, allowing its application in the therapy of different diseases, including articular cartilage injuries, which induce the establishment of a pro-regenerative microenvironment in the injured tissue. Therefore, our objective was to isolate, characterize and differentiate cartilage cells from different joints of New Zealand rabbit (Oryctolagus cuniculus), in order to verify their potential as MSC for future clinical use. For this, cartilage fragments were isolated from the humerus-radio-ulnar joints, humeral scapula, femoro-tibio-patellar, and lame femoris from rabbits.

Evaluation of immunohistopathological profile of tubular and solid canine mammary carcinomas.

Breast cancer is the most common cancer in women, but the incidence of mammary carcinoma in female dogs is even higher than in humans. These two tumors have similarities that can be seen by its biological behavior, molecular genetic alterations, and histology. This suggest that female dogs can be an excellent model for preclinical oncological studies.

Streptococcal acute pharyngitis.

Acute pharyngitis/tonsillitis, which is characterized by inflammation of the posterior pharynx and tonsils, is a common disease. Several viruses and bacteria can cause acute pharyngitis; however, Streptococcus pyogenes (also known as Lancefield group A β-hemolytic streptococci) is the only agent that requires an etiologic diagnosis and specific treatment.
