TL;DR: Analysis of data from a prospective epidemiological study in which a large number of men and women were traced for six years after they answered a detailed questionnaire found death rates from coronary heart disease, hypertensiveHeart disease, and stroke were found to be considerably higher among subjects with short-lived parents.
Abstract: This paper is based upon an analysis of data from a prospective epidemiological study in which a large number of men and women were traced for six years after they answered a detailed questionnaire. The subjects were divided into seven groups according to the longevity of their parents and grandparents. Death rates from coronary heart disease, hypertensive heart disease, and stroke were found to be considerably higher among subjects with short-lived parents than among subjects with long-lived parents. This was found to be the case for coronary heart disease among men without a history of high blood pressure or diabetes, who were not seriously overweight, who took some exersise, and who never smoked cigarettes regularly.

TL;DR: There have been many changes in col lecting and reporting nationwide can cer statistics in the United States dur ing the past 70 years and the problems they create for the statistician are discussed.
Abstract: Statistics provide some of our most reliable evidence in the study of cancer. Cancer statistics are, however, as liable to misinterpretation as any other data and using them effectively requires a thorough understanding of the limita tions of the available information. There have been many changes in col lecting and reporting nationwide can cer statistics in the United States dur ing the past 70 years. The following is a discussion of some of these changes and the problems they create for the statistician.

TL;DR: In men, the thickness of arteriole walls was greater in smokers than nonsmokers and increased with age, and the thickness was less, on the average, among cigar and pipe smokers than cigarette smokers.
Abstract: Three studies were made of the thickness of myocardium arteriole walls in relation to smoking and age. One was done on men at autopsy. Two were done on beagle dogs. In men, the thickness of arteriole walls was greater, on the average, in smokers than nonsmokers and increased with age. Thickness of arteriole walls increased with number of cigarettes smoked per day. The thickness was less, on the average, among cigar and pipe smokers than cigarette smokers. In two experiments beagle dogs daily inhaled cigarette smoke through tracheostomae; others were not exposed. The arteriole walls became thicker in smoking dogs than in nonsmoking dogs; thicker in dogs smoking many cigarettes than in dogs smoking fewer cigarettes; thicker in dogs smoking nonfilter cigarettes than in dogs smoking filter-tip cigarettes. The thickness of arteriole walls increased with duration of smoking.

TL;DR: An analysis of age-adjusted mortality by sex for the various sites of cancer for country-of-birth groups of the 25–64-year-old non-Puerto Rican white population of New York City, 1949–1951, classified jointly by religious group and socioeconomic class finds a rather consistent upward progression of rates with decreasing socioeconomic class.

TL;DR: In these studies, the DF32P leukokinetic technique has been modified so that neutrophil kinetics may be studied in the nonsteady state, allowing measurement of cell flow rate in and out of the circulating granulocyte pool.

TL;DR: It was shown that mannose and galactose could also depress the rate of growth of these tumor cells in culture and showed the same histological appearance as the tumor from which the cell line was derived.
Abstract: Different concentrations of L-fucose uniformly produced a suppression in the growth rate and a change in the morphology of cells grown in tissue culture. The inhibition of growth of these malignant cells was found to he concentration dependent with 100% inhibition of growth at a concentration of 50 mg fucose per milliliter of medium and 60% inhibition at a concentration of 12.5 mg fucose per milliliter medium. Using other sugars that are components of the glycoproteins, it was shown that mannose and galactose could also depress the rate of growth of these tumor cells in culture. When 0.05 ml of packed tumor cells used in these experiments was resuspended in 1 ml of medium and injected into a rat, a tumor grew at the site of injection. This new tumor exhibited similar growth characteristics and showed the same histological appearance as the tumor from which the cell line was derived.

TL;DR: The American Cancer Society attempts to communicate information about cancer control and to develop an understanding of the cancer problem to assist physicians in acquiring skills needed for early detection and prompt management of cancer.
Abstract: The American Cancer Society attempts 1) to communicate information about cancer control and the American Cancer Society 2) to develop an understanding of the cancer problem 3) to assist physicians in acquiring skills needed for early detection and prompt management of cancer and 4) to cultivate an interest in the cancer problem An important part of the Professional Education program is the organization of medical and scientific conferences The landmark meeting was in 1924 when a symposium was held where perspectives in cancer research were outlined In 1969 the 1st National Conference on Cancer of the Breast was held; another was held in 1971 These conferences and symposiums have been invaluable to the American Cancer Society
