Race as Witchcraft. An Argument against Indiscriminate Eliminativism about Race
No full textIn this chapter we address the problem of whether we should adhere to indiscriminate radical eliminativism about race and erase any reference to human race from scientific and medical discourse. Our answer is that total and indiscriminate eliminativism would be a mistake. Our position, however, is not based on the thesis that there are such things as human races. Quite the contrary, we show that the response coming from the sole field of study entitled to determine the ontological status of human races, i.e. population genetics, is that, loosely speaking, there are not such things as races. Still this conclusion should not put an end to the story. Also if race is on a par with witchcraft, we show not only that there are some phenomena that we cannot adequately explain without resorting to a non-referring concept, but also that some of these phenomena are biological phenomena. In particular, race is a biologically significant and ineliminable variable from social epidemiology; the mere fact that races “do not exist” is simply not relevant enough to decree that the concept of race should be eliminated from epidemiology in the face of its epistemological indispensability as a variable tracking the effects of all of the causal pathways going from racism to disease
Left ventricular venting for extracorporeal life support in pheochromocytoma: Letter to the Editor – response
No full textDevelopments in surgical techniques for coronary revascularization
No full textThe wider application of arterial conduits represents a current trend in myocardial revascularization. More complex and demanding surgical techniques are being developed as alternatives to traditional grafting procedures, in order to permit total arterial revascularization in patients with diffuse coronary artery disease. The rationale behind this strategy is the expected higher long-term patency rate of arterial conduits as compared with vein grafts. Avoidance of proximal anastomoses is another argument in favor of coronary revascularization with arterial grafts, particularly in patients with atherosclerotic changes in the ascending aorta. Although the reported operative results are good, total arterial revascularization in multivessel disease is a complex procedure, and serious perioperative complications are possible. In planning the revascularization strategy, therefore, the surgeon should take into account age, clinical condition, coexisting medical problems, coronary anatomy, and left ventricular function. The method of myocardial revascularization is an important aspect of the surgical procedure and plays a major role in the outcome of the operation in the presence of severe left ventricular dysfunction or when the operation requires prolonged ischemic times. To avoid the inevitable damaging effects of cardiopulmonary bypass and aortic cross-clamping, myocardial revascularization is carried out without extracorporeal circulation. This technique should be part of the armamentarium of the cardiac surgeon and should occasionally be considered in patients who have serious coexisting medical problems or severe left ventricular dysfunction

Abstract
Cardiac Troponin I (cTnI) is a polypeptide involved in myocardial contraction and has been shown to be a highly sensitive biomarker of myocardial injury in humans. Chronic myocardial ischemia was induced in eight adult sheep by anterior coronary artery legation. Forty-five days after coronary artery legation, sheep underwent autologous myoblasts implantation to the infarct area to improve local tissue regeneration. Blood samples were taken at regular intervals before and after the induced coronary ischemia and myoblast implantation and serum levels of cTnI were assessed with chemiluminescent immunodosage using a commercially available anti-human cTnI monoclonal antibody. cTnI levels began to increase the day after coronary legation and after myoblast implantation and gradually recovered to physiological levels in the next 14 days. Furthermore, the commercial anti-human antibody was shown to completely cross react with the ovine polypeptide as well as with canine, swine and equine sera

No full textAppropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
