Gore proposes genetic engineering commission

Briefly noted is Rep. Albert Gore's introduction of legislation to create a commission to review developments in genetic engineering with potential human application. The proposed commission would consider medical, legal, ethical, and social implications of this research. It would be a purely advisory commission composed of six scientists; six experts in law, theology, ethics, or the social sciences; and three laymen.     

The Management of Prostaglandin-controlled Breeding Programs in Beef Cattle - A Five Year Study

A herd of 180 beef cows was synchronized with prostaglandin and bred by artifical insemination for five successive years. Factors influencing the success or failure of estrus synchronizing programs were identified, including the management of nutrition, postpartum interval, cow age and artificial insemination technology. Specific recommendations on the management of prostaglandin-controlled breeding programs resulted in improving the pregnancy rates from 33% in year 1 to 67% in year 5. Improved management and close veterinary supervision were shown to improve the success of an estrus synchronization program.     

Membrana nictitans gland cyst in a dog

A cyst involving the gland of the 3rd eyelid was removed from an 8-year-old dog. Clinically the circumscribed mass resembled a pigmented neoplasm. Histologically the cyst was multiloculated, with homogeneous eosinophilic periodic acid-Schiff-positive content. Melanin pigment was present in epithelial cells and cystic lumens. Protective functions of the 3rd eyelid were retained following excisional biopsy.     

U.s. Transit subsidy policy: in need of reform

Public transit in the United States has depended increasingly on public subsidies since the inception ofthe federal mass transit assistance program in the early 1960s. The subsidies are associated with declining efficiency and labor productivity, as urban transit systems have overcapitalized, simplified fare structures, and extended service into sparse suburban markets. Despite these subsidies, transit has not proved successful in countering the effects on its market of increased automobile ownership and use and of decentralizaton of residences and places of employment.
