Studies reveal that surface waters worldwide are contaminated with hormonally active agents, many released from sewage treatment plants. Another potential source of aquatic hormonal contamination is livestock feedlot effluent. In this study, we assessed whether feedlot effluent contaminates watercourses by measuring a) total androgenic [methyltrienolone(More)
In cultured nerve cord explants from the crayfish (Procambarus clarkii), the normal impulse activity levels of growing motor axons determine their response to Ca2+ influx. During depolarization or Ca2+ ionophore application, normally active tonic motor axons continue to grow, whereas inactive phasic motor axons retract and often degenerate. To determine the(More)
A complex network of interactions between the stroma, the extracellular matrix and the epithelium drives mammary gland development and function. Two main assumptions in chemical carcinogenesis of the mammary gland have been that carcinogens induce neoplasia by causing mutations in the DNA of the epithelial cells and that the alterations of tissue(More)
There is mounting evidence that the stroma plays a crucial role in mammary gland carcinogenesis. Here, we report that mammary gland stroma from mature and multiparous rats prevents neoplastic development and encourages normal ductal growth of grafted epithelial cancer cells. Fifty thousand epithelial cancer cells were injected into the cleared fat pads of(More)
OBJECTIVE To determine whether the ratio of pulse oximetry saturation/fraction of inspired oxygen (SpO2 /FiO2 , [SF]) correlates with the ratio of partial pressure of oxygen in arterial blood/FiO2 (PaO2 /FiO2 , [PF]) in dogs. DESIGN Prospective, observational pilot study. SETTING Urban tertiary veterinary referral center. ANIMALS Thirty-eight(More)
OBJECTIVES To review the physiology of micturition, the pathophysiology of micturition disorders, and current pharmacological agents used to treat these disorders. To discuss different urinary catheterization techniques, along with the risks of catheter-associated urinary tract infections attributed with these techniques. ETIOLOGY Many critically ill(More)
