Testicular weight is a valuable measure of gonadal development in laboratory mice, but is usually only obtainable postmortem. The objective was to assess the utility of antemortem, noninvasive methods of predicting testicular weight and volume in peripubertal mice. Body weight, scrotal width, and ul...

BACKGROUND Myocardial fibrosis is a hallmark of hypertrophic cardiomyopathy (HCM). Human patients with HCM have high serum concentrations of biomarkers of collagen synthesis, indicating a profibrotic state. This abnormality exists in sarcomere mutation carriers both with and without overt left ventr...

A free-ranging adult female red-tailed hawk died suddenly after 3 weeks in rehabilitation for a radial fracture. Cause of death was septic thrombosis from a chronic bacterial valvular endocarditis, probably associationed with injury at the fracture site. The challenge of clinical diagnosis of sepsis...

The effects of 2 different 8-hour continuous rate infusions (CRIs) of medetomidine on epinephrine, norepinephrine, cortisol, glucose, and insulin levels were investigated in 6 healthy dogs. Each dog received both treatments and a control as follows: MED1 = 2 μg/kg bodyweight (BW) loading dose follo...
