Physiology of the European brown bear (Ursus arctos arctos)
Although the American black (Ursus americanus) and American brown (grizzly) (Ursus arctos horribilis) bears have been the subjects of intensive physiological research, very little so far, has been done to understand the physiology of the European brown bear (Ursus arctos arctos). In our laboratory the research on the physiology of European brown bears started 10 years ago. Between 1987 and 1997...
متن کاملPlatelet function in brown bear (Ursus arctos) compared to man
BACKGROUND Information on hemostasis and platelet function in brown bear (Ursus arctos) is of importance for understanding the physiological, protective changes during hibernation. OBJECTIVE The study objective was to document platelet activity values in brown bears shortly after leaving the den and compare them to platelet function in healthy humans. METHODS Blood was drawn from immobilize...
متن کاملFallot's tetralogy in a European brown bear (Ursus arctos).
A congenital heart malformation was diagnosed in a free-ranging adult female European brown bear (Ursus arctos) found dead due to intraspecific violence. At necropsy, the heart had all four features of Fallot's tetralogy. No further malformations were identified in the animal, which was of normal size and weight for its age, in normal body condition, and had probably borne young. The heart cond...
متن کاملHumeral chondrosarcoma in a Hokkaido brown bear (Ursus arctos yesoensis).
Humeral chondrosarcoma was found in an 18-year-old male Hokkaido brown bear (Ursus arctos yesoensis). Necropsy revealed a large firm mass under the left superficial pectoral muscle at the axillary region. The mass involved the left shoulder joint and peripheral muscles, and connected to the head of the humerus with osteolysis. Histopathologically, the mass was composed of irregularly shaped myx...
متن کاملAdipose-derived stem cells from the brown bear (Ursus arctos) spontaneously undergo chondrogenic and osteogenic differentiation in vitro.
In the den, hibernating brown bears do not develop tissue atrophy or organ damage, despite almost no physical activity. Mesenchymal stem cells could play an important role in tissue repair and regeneration in brown bears. Our objective was to determine if adipose tissue-derived stem cells (ASCs) can be recovered from wild Scandinavian brown bears and characterize their differentiation potential...
