Abstract (sommario):
The fitness costs and benefits of conforming to ones ingroup vary depending upon the dangers inherent in the immediate environment. In threatening environments, conformity is likely to be more beneficial than it is in less threatening environments. One specific threat that has had a profound selective influence on humans is infectious disease. Therefore, it was predicted that cultures inhabiting regions where risk of disease transmission is high would have more conformist orientations. Across four divergent measures of conformity, this was shown to be the case. Laboratory manipulations of dise

Aspirin is the most commonly used antiplatelet drug in the secondary prevention of cardiovascular events. Many patients experience thromboembolic events despite daily aspirin therapy.

The present work focuses on the unresolved issues of the epidemiology and treatment of BV in order to provide valid methods for treatment studies of this condition and to describe the prevalence of BV in defined populations.

Geostatistical methods are increasingly used in low-resource settings where disease registries are either non-existent or geographically incomplete. In this thesis, which is comprised of four papers, we address some of the common issues that arise from analysing disease prevalence data. In the first paper we consider the problem of combining data from multiple spatially referenced surveys so as to account for two main sources of variation: temporal variation, when surveys are repeated over time; data-quality variation, e.g. between randomised and non-randomised surveys.

Abstract (sommario):
Nigeria has the second highest number of people living with HIV in the world. Since 1986 when the first case of the Acquired Immune Deficiency Syndrome (AIDS) was reported in Nigeria, the disease has grown to epidemic proportions with the prevalence of its causative agent - the Human Immunodeficiency Virus (HIV) being observed to be steadily rising since the early days of the epidemic. Therefore it is important to talk about the prevalence of HIV infection in Nigeria. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/32301

Evaluation of factors associated with HPV infection based on complete anogenital sampling and with HPV-16 antibody detection may lead to a better understanding of HPV transmission and prevention.Methods: A total of 493 asymptomatic men ages 18 to 40
