Mammary tumors are the third most common tumor in cats after cutaneous neoplasia and lymphosarcoma. More than 80% of feline mammary tumors are adenocarcinomas, which are similar to human mammary adenocarcinomas in their biologic behavior and histologic characteristics. Despite treatment with radical mastectomy, feline mammary adenocarcinoma is associated with a...
Research has shown that more efforts are needed to increase high school completion and postsecondary enrollment among Latino youths. However, little is known regarding efforts that engage both Latino youths and their parents. To address this gap, we surveyed Juntos Oregon participants to examine the school and community context Latino...
This study reports the design, construction, and evaluation of an automatic cardiac massage device and support system. The design incorporates the principle of a cardioplethysmograph operated in reverse, such that pneumatic power fed to the prosthesis will mechanically impart a massaging action to the heart. Basically, the prosthesis is a...
In 1959 the British Ornithological journal, The Ibis, published a centenary commemorative volume on the history of ornithology in Britain. Over the previous few decades, the contributors to this volume had helped focus the attention of ornithologists on the methods, priorities, and problems of modem biology, specifically the theory ofevolution...
