Analytical and morphometric study of nutrient foramina of femur and its clinical implications

Background: The femur is supplied princially by the diaphyseal nutrient artery which enters the bone throught the nutrient foramen. This supply is essential during the growing period, the early phases of ossification, and in different surgical procedures. The aim of present study was to examine the morphology and topography of the femur nutrient foramen to provide detalied data on such features.Methods: This was a cross-sectional-descriptive study in which we observed 50 femurs. We analysed the number and location of nutrient foramina, the length of the bone, the position of the nutrient foramen regarding to values of FI, correlation between number of nutrient foramen and length of femur, correlation between position of nutrient foramen and side of extremity to which femur belongs.Results: The double foramina were common in right (57.1%) and left (42.1%) femur, mostly located in medial lip of aspera line in right (64.3%) and on the lateral lip in left femur (68.4%), with statistically significant correlation, χ = 4.85; p = 0.03, p 0.05). There is positive correlation between length of right and left femur and number of foramina.Conclusions: The study provides data of the nutrient foramina on femur, which is helpful for clinicians to help preserve bone vascularization during surgery

Poikilocytotic forms caused by hyperthermia and heat stroke- experimental study on Wistar rats

Background: The aim of the study was to find out what happens to erythrocytes and their forms during life and after death as a result of high water temperature.Methods: Heat stress was used on a rat model.to investigate the effects of different temperature intensities (37°C and 44°C) and exposure time (20 min and until the time of death) on erythrocyte morphology. Total of 23 Wistar rats were divided into two groups: 37°C as control group and 44°C as trial groups. The trial groups were classified into antemortem the exposure time of 20 min and postmortem groups exposure time until fatal outcome. The anaesthetised rats were exposed to preheated water using the water bath. May-Grünwald-Giemsa colouring technique was applied on blood samples taken from the abdominal aorta. Results: Exposure of Wistar rats to water temperature in groups KG37 and G44 led to a significant changes in core temperature. In the control group, the thermoregulatory mechanism established normothermia, and in G44 hyperthermia was detected during 20 minutes of exposure. The frequency of heat stroke in group G44 was 43.8%. Target cells and anulocytes were predominant in antemortem group at 44°C, while anulocytes and spherocytes in postmortem groups 44°C, respectively. Dacryocytes with spherocytes were significantly higher in postmortem group 44°C than in antemortem group 44°C (p=0.002, p=0.017, respectively).Conclusions: Poikilocytosis is associated with the exposure length and temperature intensity. Following a fatal outcome dacryocytes with spherocytes at 44°C were significantly more than in corresponding antemortem groups

<b>LONG BITTER ENEMIES NO MORE: IENGO CORPORATE PARTNERSHIPS AS A NEW PATHWAY TO INFLUENCE IN GLOBAL ENVIRONMENTAL GOVERNANCE</b>

This dissertation examines how partnerships between leading environmental non-governmental organizations (IENGOs) and corporations shape the agency of nonstate actors in global politics. It contributes to the growing scholarship on non-substantialist approaches to the concept of agency in International Relations (IR) by analyzing how interactions between nonstate actors can influence their ability to act and exert influence in global politics. The central concept of agency reconfiguration is introduced. This concept argues that IENGO-corporate partnerships can create opportunities for nonstate actors to gain new capacities and influence in global politics. However, it also acknowledges potential trade-offs associated with such partnerships. To explore this concept, the dissertation first maps the landscape of IENGO-corporate partnerships. This includes a comprehensive list of corporate partners for four leading IENGOs (Greenpeace, EDF, FoE, and WWF), how these partnerships have evolved over time, and a typology of partnership structures. Finally, a process tracing approach is used to examine a specific case: the partnership between Greenpeace and Foron, a former German appliance manufacturer. Within-case evidence is used to link the events from the formation of the partnership to Greenpeace's agency reconfiguration, which ultimately positioned Greenpeace as a central actor in ozone governance, particularly the implementation of the Montreal Protocol.</p
