Feeding dynamics and performance of Beetal does in relation to body condition score at the time of mating

The body condition of does at the time of mating may affect feeding patterns and production performance during forthcoming lactation. For investigation, 40 Beetal does available for breeding were utilized, and their body condition score (BCS) was estimated using the visual-cum-palpation method with a 9-point scale (scale of 1=5 with increments of 0.5 point). The available goats...

Estradiol 17 beta-dehydrogenase 5 is involved in aflatoxin B1 transportation

Numerous studies have focused on the mechanism of aflatoxin B1 (AFB1) metabolism and its carcinogenic mechanism, but how AFB1 is transported into hepatocytes and how it is transferred inside hepatocytes remains unknown. In this study, the AFB1-interacting protein, estradiol 17 beta-dehydrogenase 5 (Akr1c6), was identified with an immobilized affinity chromatography technique and...

Aggressive osteoblastoma of the cervical vertebrae in a Turkish Angora cat

Aggressive osteoblastoma is a type of bone tumor rarely reported in veterinary literature. Osteoblastoma may be misdiagnosed as an osteosarcoma, which is a well-understood malignant bone tumor. Owing to poor prognosis, animals diagnosed with osteosarcoma are not always treated. In the present case, we diagnosed the tumor as aggressive osteoblastoma on the basis of macroscopic...
