Reports that people who are predominantly left-handed apparently are able to withstand moderate brain damage with relatively few of the motor problems observed in right-handed victims of brain damage. Other brain-related differences between left- and right-handed individuals are also noted. (JN)

Presents seven dietary guidelines on ways to reduce the risk of contracting cancer, discussing scientific evidence supporting the guidelines. Includes a list of foods indicating possible role in cancer, sources, recommendations related to amount/frequency of intake, and hazards of megadoses. Foods cited include fats, vitamins, alcohol, caffeine,…

Part 1 of this evaluation of dietary supplements and health aids (SE 533 788) focused on various therapeutic claims made for vitamins and minerals. This part examines health-promoting claims made for selected macronutrients and fiber. Macronutrients examined include selected proteins, amino acids, enzymes, carbohydrates, and lipids. (JN)

Scientists doing research on primates are increasingly being subjected to threats and acts of violence from animal rights groups. The intimidation has resulted in many laboratories taking extensive security measures. Some scientists claim, however, that there is no surrogate for animal research in understanding human diseases. There are fears that…

Traces the history of the antivivisection movement, examining issues related to the use of animals in studying the cause of rabies. Also discusses issues related to the current controversy over animal experimentation. (JN)

The regulations prescribed by the Department of Health, Education, and Welfare regarding human subjects research are examined including their effects on research procedures. (MM)

Clinical investigations have established that an aggressive approach to lowering cholesterol levels in coronary heart disease patients is warranted. This article describes optimal goals and discusses the role of diet, exercise, and medication in plasma lipids management. (IAH)

This report summarizes advances in the understanding of Alzheimer's disease, the major cause of mental disability among older Americans. The demography of the disease is discussed, noting that approximately 2.5 million American adults are afflicted with the disease and that the large increase in the number of Alzheimer's disease patients is due to…

The use of microelectronics and computers in medicine is reviewed, focusing on medical research; medical data collection, storage, retrieval, and manipulation; medical decision making; computed tomography; ultrasonic imaging; role in clinical laboratories; and use as adjuncts for diagnostic tests, monitors of critically-ill patients, and with the…

Explains why the research requirement of the resident curriculum should be developed around the scientific method. The method can be stated in the form of: (1) make an observation; (2) make a hypothesis; (3) test the hypothesis; and (4) reach a conclusion. When research topics are broken down under these main steps, residents can see a more…

Discusses possible reasons why the death rate from heart disease is falling. Three phenomena that are considered partly responsible are: (1) early diagnostic technology; (2) the existence of new tools for treating the disease; and (3) public awareness of risk factors. A prescription for a healthy heart is provided. (BC)
