teratomas are rare germline tumors that originate from one or more embryonic germ cell layers. teratoma of the kidney is extremely rare, and less than 30 cases of primary intrarenal teratomas have been published to date. we report the main radiologic features of an unusual case of mature cystic teratoma arising from the left kidney in a two-year-old boy. a left-sided abdominal mass was detected...

Mammalian microtubule-associated protein 2 (MAP2) exists in high-molecular-weight (Mr approximately 280,000) and low-molecular-weight (Mr approximately 70,000) forms, with the latter protein being more abundant in embryonic brain homogenates than in preparations from mature brain (Riederer and Matus, 1985). In the current study, we have shown that avian MAP2 also exists as both high- (Mr approx...

Isolated-housing conditions (a single mouse in cage) have been reported to induce various changes in physiological and behavioral characters of mice comparing with collective-housing conditions. However, the effect of age and sex has not been studied in detail. In this report, the young (8 or 11 weeks old) and the mature (29 weeks old for male and 32 weeks for female) of both sexes were compara...

A new model was developed to provide Australian pig breeders with an ability to estimate economic values and economic weights of key traits in a way that was more flexible and relevant to pig producers. Economic weights were converted using a genetic standard deviation scalar so that the relative contributions of each trait to the overall maternal breeding objective could be made. Number of pig...
