Calcinosis Circumscripta with Iron Mineralization in an African Green Monkey (Chlorocebus aethiops sabaeus).

A 19-y-old, colony-born, female African green monkey (Chlorocebus sabaeus) presented for recurrent swelling measuring 11 × 5 × 4 cm on the right thigh, around the stifle, which started 5 y previous, resulting in lameness. The affected area had alopecia and crusting and felt lobulated on palpation. Radiographic evaluation revealed multiple foci of well-circumscribed, soft-tissue mineralization within the subcutis and underlying muscles.

Morphological, Histological and Morphometrical Aspects of Auditory Ossicles in Pig Fetuses ().

The detailed study of the morphology and morphometrics of the auditory ossicles in swine became a topic for investigation due to their resemblance to the human ear. The methods used in this study cover the typical macroscopical investigation of gross morphology: a detailed metrical and histological assessment through H&E standard protocol on auditory ossicles originating from eight pig fetuses originating from four distinctive sows. The ossicular assembly in the malleus, incus and stapes present in 66-day fetuses shows all the features generally described in swine.

Ketoconazole-Fumaric Acid Pharmaceutical Cocrystal: From Formulation Design for Bioavailability Improvement to Biocompatibility Testing and Antifungal Efficacy Evaluation.

Development of cocrystals through crystal engineering is a viable strategy to formulate poorly water-soluble active pharmaceutical ingredients as stable crystalline solid forms with enhanced bioavailability. This study presents a controlled cocrystallization process by cooling for the 1:1 cocrystal of Ketoconazole, an antifungal class II drug with the Fumaric acid coformer. This was successfully set up following the meta-stable zone width determination in acetone-water 4:6 (/) and pure ethanol.

Ocular and perineal squamous cell carcinomas in a Holstein Friesian cow.

Background: Squamous cell carcinoma (SCC) in domestic cattle is an economically significant malignant neoplasm and has been documented primarily in ocular and periocular tissues, vulva, and perineum. SCCs are often slow-growing and locally invasive, but metastasis is uncommon. Increased risk of developing SCC has been predominantly associated with high levels of sunlight exposure and hypopigmentation (skin and conjunctiva).

Chronic Copper Bilysinate Poisoning in Five Texel Sheep: A Case Report.

Copper is an essential trace element but becomes toxic in overexposed animals. Sheep are the domestic species most prone to chronic copper poisoning, as a slight increase in the dietary concentration can lead to liver accumulation and the development of clinical signs in this species. Common sources of copper in the diet are feed additives and mineral supplements, which are commonly used in pigs and poultry.
