Morphometric Effect of Erythropoietin Used as Doping and Swimming Exercise in Female Rats in Puberty on Humerus and Femur Bones

In this study, the effect of human erythropoietin (rhEPO) with aerobic exercise on the femur and humerus bone of female rats in the pubertal period was investigated by morphometric method. The study was performed on 40 female rats of the Spraque – Dawley genus. The rats were divided into four groups as erythropoietin, swimming exercise with erythropoietin, swimming and sedentary. For 4 weeks, every other day all rats were injected with rhEPO (100 IU / kg, IP) 4 days a week. After the injection, the swimming group with rhEPO and the solo swimming group were swam for 30 minutes. At the end of 4 weeks, the rats were euthanized, and corpus, height and cortex and cavum medulla measurements of humerus and femur bones were done. Statistical evaluation also indicated that there were no differences (p>0.05) between rhEPO group, swimming group and rhEPO + swimming group femur length and femur cavum medulla da sedentary group. Sedentary group was found to be thicker (p<0.05) in femoral Corpus than swimming and rhEPO group, while there was no statistical difference in femoral cortex but a numerical difference was found. While Humerus bone length and Corpus were not significant in our study (p>0.05), although the numerical values of rhEPO + swimming group in Cortex and Cavum medullada were different compared to other groups, no statistical difference was found (p > 0.05). As a result, it is thought that long-term use of erythropoietin may cause bone development disorders.

Growing up in Hospitaller Malta (1530-1798) : sources and methodologies for the history of childhood and adoloscence

The study of young people in the past is fraught with methodological problems and unearthing source material on children and adolescents can be problematic. It requires the adoption of a different set of lenses through which textual primary material can be viewed. This entails striving to recognise and release previously unheard voices. Furthermore, the textual material can be complemented by an array of visual and material objects that have preserved a certain image of children and adolescents in the past. This chapter commences with a brief outline of the methodological developments that have taken place in this field since Philippe Ariès’s seminal book appeared in 1960, and traces the resulting changes and innovations that concern sources. In particular, it will underline the importance to historians of taking into account recent developments in the field of childhood archaeology. Furthermore, the fundamental role of religion in people’s lives in early modern times necessarily influenced their upbringing. In turn, most of the sources that are available from this era – court records, statutes, paintings – were either produced by religious institutions, or were heavily influenced by religious beliefs. Thus, this chapter will strive to demonstrate how approaches used in one place can be adapted and used in different historiographical contexts, and how vital it is to adopt an interdisciplinary approach.peer-reviewe
