Strigiformes are an order of raptorial birds consisting exclusively of owls: the Tytonidae (barn owls) and the Strigidae (true owls), united by a suite of adaptations aiding a keen predatory lifestyle, including robust hind limb elements modified for grip strength. To assess variation in hind limb morphology, we analysed how the dimensions of the major hind limb elements in subfossil and modern...

OBJECTIVE To determine the effect of weight reduction on clinical signs of lameness among overweight dogs with clinical and radiographic signs of hip osteoarthritis. DESIGN Nonblinded prospective clinical trial. ANIMALS 9 client-owned dogs with radiographic signs of hip osteoarthritis that weighed 11 to 12% greater than their ideal body weight and were examined because of hind limb lameness...

In vivo animal model systems, and in particular mouse models, have evolved into powerful and versatile scientific tools indispensable to basic and translational research in the field of transplantation medicine. A vast array of reagents is available exclusively in this setting, including mono- and polyclonal antibodies for both diagnostic and interventional applications. In addition, a vast num...

OBJECTIVE Adaptation to ischemia by brief episodes of ischemia and reperfusion (preconditioning) of the heart protects the heart against sustained ischemia, where the transcription factor nuclear factor kappa-B (NFkappaB) appears crucial for the protection. Preconditioning of the heart may even be evoked by brief episodes of ischemia and reperfusion in other organs. The present study investigat...

OBJECTIVE To establish a protocol to collect temporal-spatial gait analysis variables by use of a portable walkway system in Labrador Retrievers at a walk and to determine reference values. ANIMALS 56 healthy Labrador Retrievers. PROCEDURES 6 passes across the walkway (3 passes in each direction) were recorded. Inclusion criteria for a pass were that the dog was at a walk (velocity, 60.0 to...

we investigated sexual size dimorphism in the tree frog, hyla savignyi using 33 males and 22 females from the western and northwestern regions of kermanshah province, western iran. out of sixteen measured morphometric characters, four were significantly larger in females than in males. these characters were nostrileye length, brachium length, elbowlongest finger length and hind limb length.
