    • Psychological dysfunctions in lead-exposed workers: Relation to biological parameters of exposure. 

      Grandjean, Philippe; Arnvig, E; Beckmann, J (Nordic Association of Occupational Safety and Health, 1978)
      Insidious neurotoxic effects of lead have been studied in a population of 42 lead-exposed workers and a reference group of 22 comparable workers with no lead exposure. The age of the individuals ranged from 18 to 50 years. ...

      Frisch, Rose Epstein; Wyshak, Grace; Vincent, Larry (New England Journal of Medicine (NEJM/MMS), 1980)
      YOUNG female ballet dancers attending professional schools or dancing in companies in which thinness is much admired restrict their food intake and are highly active. The unusual eating habits and levels of activity of ...
    • A Profile of the Health-Promoting Behaviors of Physicians and Lawyers 

      Wyshak, Grace; Lamb, George A.; Lawrence, Robert Z.; Curran, William John (New England Journal of Medicine (NEJM/MMS), 1980)
      The federal government has increased its activities directed toward health promotion and disease prevention. We carried out a pilot survey of a random sample of Massachusetts physicians and lawyers to obtain a profile of ...
    • Evidence for a Secular Trend in Age of Menarche 

      Wyshak, Grace; Frisch, Rose Epstein (New England Journal of Medicine (NEJM/MMS), 1982)

    • Cross-reactivity to human T-lymphotropic virus type III/lymphadenopathy-associated virus and molecular cloning of simian T-cell lymphotropic virus type III from African green monkeys. 

      Hirsch, V.; Riedel, N.; Kornfeld, H.; Kanki, Phyllis Jean; Essex, Myron Elmer; Mullins, J. I. (Proceedings of the National Academy of Sciences, 1986)
      Simian T-lymphotropic retroviruses with structural, antigenic, and cytopathic features similar to the etiologic agent of human acquired immunodeficiency syndrome, human T-lymphotropic virus type III/lymphadenopathy-associated ...
    • Pregnancy during Residency 

      Sayres, Maureen; Wyshak, Grace; Denterlein, Geraldine; Apfel, Roberta Joyce; Shore, Eleanor Gossard; Federman, Daniel David (New England Journal of Medicine (NEJM/MMS), 1986)
      To identify possible barriers to women physicians who wish to combine parenting with medical careers, we studied 56 of 64 pregnancies from the past 10 years in 63 of 66 Harvard-affiliated residency programs. Pregnancies ...
    • Epidemiologic Studies Assessing the Role of the Epstein-Barr Virus in Hodgkin's Disease 

      Mueller, Nancy Elsa (Yale Journal of Biology and Medicine, 1987)
      The hypothesis that an infection plays a role in the etiology of Hodgkin's disease (HD) is suggested by both its clinical and histologic features. Its bimodal age-incidence pattern also suggests an infectious process among ...
    • Studies of acid aerosols in six cities and in a new multi-city investigation: design issues. 

      Speizer, Frank Erwin (1989)
      Techniques for measuring acid aerosols in the ambient environment have been developed only recently. As part of the on-going Harvard Study on the Health Effects of Sulfur Dioxide and Respirable Particulates, we have developed ...
    • In Vitro Models of Carcinogenesis: Expression of Recessive Genes by Chromosomal Mutations 

      Little, John Bertram (National Institute of Environmental Health Sciences, 1989)
      There has been considerable recent interest in the mechanisms by which recessive mutations involving cancer genes may be expressed. We have developed an in vitro model to study this phenomenon in an endogenous autosomal ...
    • Alcohol use and abuse in random samples of physicians and medical students 

      McAuliffe, William Edward; Rohman, Mary; Breer, Paul; Wyshak, Grace; Santangelo, Susan L.; Magnuson, Elizabeth (American Public Health Association, 1991)
      BACKGROUND: This study sought to resolve conflicting views about whether physicians are especially prone to alcohol abuse. METHODS: Using an anonymous, mailed questionnaire on substance use, we surveyed 500 physicians, ...
    • Mechanisms, Measurement, and Significance of Lung Macrophage Function. 

      Brain, Joseph David (The National Institute of Environmental Health Sciences (NIEHS), 1992)
      Macrophages exist throughout the body. They have critical roles in the peritoneal cavity, bone marrow, skin, spleen, liver, and elsewhere. Their migratory patterns, phagocytic behavior, immunologic roles, and secretory ...
    • Epidemiologic study design for investigating respiratory health effects of complex air pollution mixtures. 

      Dockery, Douglas W. (1993)
      Epidemiologic studies of the respiratory health effects of air pollution are intrinsically difficult because exposure is common, expected effects at concentrations found in developed countries are weak, random misclassification ...
    • Computer Model Challenges Breast Cancer Treatment Strategy 

      Retsky, Michael W.; Swartzendruber, Douglas E.; Bame, Paul D.; Wardwell, Robert H. (Informa UK Limited, 1994)
      The breast cancer treatment failure rate remains unacceptably high. The current breast cancer treatment paradigm, based primarily on Gompertzian kinetics and animal models, advocates short-course, intensive chemotherapy ...
    • Biomarkers of chemical exposure: state of the art. 

      Grandjean, Philippe; Brown, SS; Reavey, P; Young, DS (American Association for Clinical Chemistry, 1994)
      Establishing associations between environmental agents and disease presents challenges to both epidemiologists and toxicologists, particularly in cases of complex gene-environment interactions and when there is a long ...
    • In vivo evaluation of chemical biopersistence of nonfibrous inorganic particles. 

      Brain, Joseph David; Godleski, John Joseph; Kreyling, W (1994)
      The lung's response to deposited particles may depend upon the physical-chemical properties of the particles, the amount initially deposited, and the persistence of the particles. Clearance involves mucociliary transport ...
    • Diet, nutrition, and avoidable cancer
