Natural disasters and the rise of zoonotic diseases: A case of post-earthquake disseminated cryptococcosis in a dog.

Cryptococcosis is a systemic zoonotic disease that is challenging to diagnose based on clinical findings in cats and dogs due to the nonspecific nature of its clinical presentation. This case report aims to document the first confirmed case of disseminated cryptococcosis caused by Cryptococcus neoformans in a dog in Turkey and to highlight the potential link between natural disasters such as earthquakes and the emergence of zoonotic diseases in domestic animals. A two-and-a-half-year-old spayed female Cocker Spaniel presented with increased respiratory sounds, skin lesions, facial swelling and enlarged lymph nodes.

Unlocking immunotherapy targets: programmed death 1 and its ligand and their correlation with tumour grade in feline injection site sarcoma.

In this study, the immunohistochemical expression of programmed cell death 1 (PD-1) and programmed cell death ligand 1 (PD-L1), which could facilitate a novel approach to immunotherapy for feline injection site sarcomas (FISSs), was investigated. Treatment strategies based on the suppression of this pathway are possible for tumours expressing PD-1/PD-L1. In this context, FISSs were histologically classified, the grade of sarcoma and the intensity of lymphocyte infiltration determined and PD-1 and PD-L1 expression evaluated in tumours of different grade.

Malignant peripheral nerve sheath tumour of the cerebellopontine angle in a cat.

Malignant peripheral nerve sheath tumour is an uncommon tumour in cats. The current case report aims to present the diagnosis, treatment and histopathology of a malignant peripheral nerve sheath tumour that developed in the cerebellopontine angle region of a cat. A 4-year-old 4.

Comparative evaluation of platelet-rich plasma, autologous blood serum, and umbilical cord serum for corneal healing after penetrating keratoplasty in New Zealand rabbits.

This study aimed to evaluate the effects of platelet-rich plasma (PRP), autologous blood serum (ABS), and umbilical cord serum (UCS) on corneal healing following penetrating keratoplasty (PK). A total of 120 New Zealand white rabbits, forty were designated as donors, while the remaining eighty rabbits were randomly divided into four groups after undergoing PRP Group (n = 20), ABS Group (n = 20), UCS Group (n = 20) and Control Group (n = 20). Corneal opacity score, corneal vascularization, corneal staining, histopathological analysis, and immunohistochemical analysis (including CD4, CD8, and major histocompatibility complex [MHC] II) were assessed at postoperative 1, 2, 3, and 12 weeks.

Effects of fish oil on methotrexate-induced reproductive damage in rats.

Methotrexate (MTX) is a folic acid antagonist that is commonly used in paediatric and adult oncology to treat a variety of malignancies. Internal organs, including the testis, are severely cytotoxic and genotoxic to MTX. Omega-3, as an antioxidant, has been shown to protect rat testis tissue from injury.
