The APS Journal Legacy Content is the corpus of 100 years of historical scientific research from the American Physiological Society research journals. This package goes back to the first issue of each of the APS journals including the American Journal of Physiology, first published in 1898. The full text scanned images of the printed pages are easily searchable. Downloads quickly in PDF format.
Between 1965 and 1983, a total of 138 patients with endocrine hypertension were treated at the Münster Surgical Clinic. 71 catecholamine-producing tumors were removed in 56 patients, 60 patients had primary aldosteronism; 32 patients with Cushing’s syndrome reveived uni- or bilateral adrenalectomy. The operative access to the adrenals was by anterior abdominal incision which we consider superior to lateral or transthoracic approaches. 35 complications occurred. The operative management of these forms of secondary hypertension, with its low overall rate of complications, is currently seen as the most successful therapeutic approach.
separate mixtures of inorganic, ester, and nucleotide phosphates and to recover each of these in substance. The application of this information will, of necessity, be an individual one, and it seems not worth while to recommend a specific procedure of limited application. It must be kept in mind that differences in the degree of adsorption and desorption of esters and nucleotides as observed here will be encountered, and control experiments will be required (7).The growth of artificial insemination of cattle during the past 10 years has emphasized the need for adequate methods of predicting the fertility of semen samples before they are used. Laboratory studies and field operations have relied heavily on visual estimates of sperm numbers and sperm motility. These estimates have been continuously subject to the unavoidable human errors and biases encountered in collecting quantitative data with the microscope. A number of objective methods have been proposed for evaluating sperm motility (1-3). These methods have made use of the relationships among sperm numbers, area observed, distances traveled, and the time intervals between or during the observations. The objections to these methods have included such items as the need for standardization of the sperm numbers, the laborious and time-consuming techniques and calculations, the human bias, and the repeated high costs of the determinations.The ideal method of evaluating sperm separate mixtures of inorganic, ester, and nucleotide phosphates and to recover each of these in substance.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
