Background: HIV/AIDS has existed officially for more than 35 years and is now seen as a global Epidemic. The disease has claimed many victims and there is no indication showing decrease of the mortality rate. The disease is currently incurable, but antiretroviral drugs have good effect at slowing down the process. The persons who live with the disease are exposed to stigma and, sometimes, negative attitudes. The negative attitudes could affect the person?s willingness carry through the test.

This essay will examine the historical picture of the island Rapa Nui as it is portrayed in popular science and in ecohistorical literature of the university of Gothenburg. This historical picture states that the inhabitants of the island cut down a lot of trees in the process of transporting the big and heavy statues, moai, from the quarry to the platforms along the coastline of the island. During this process all trees disappeared and resulted in soil erosion. The cultivation was destroyed and brought hunger to Rapa Nui. The following rivalry for food led to a situation of war followed by a cultural collapse.

Background: The HIV-pandemic is a global concern. Everyday about 6000 adolescents become infected with HIV. The HIV-prevalence in Zambia among adolescents, between 15-24 years, were 3,8% for men and 12,7% for women in year 2005. Aim: The aim of this study was to explore adolescents` knowledge, attitudes and beliefs about HIV/AIDS in Livingstone in Zambia. Method: The sample consisted of 67 adolescents, 33 males and 34 females in age 15-24 years.

The aim of this study was to investigate whether a dietary change, physical activity or a combination of both gave the best result when treating obesity, concerning weight loss and BMI. Excessive weight and obesity are today a big health-issue and it is estimated that 10 % of the men and 12 % of the women in Sweden have a BMI over 30, i.e. are suffering from obesity. The corresponding number for children is 3 %. No one can say for sure what causes obesity but there are many theories.

The study's starting point is the cultural, economic, social and health which is relevant when different levels of society affirms. The aim has been the basis of the representation levels of society discern what is valued and given priority as well as the measures and the strategies used in implementation. The empirical data underlying the study is qualitative studies with respondents from a university, a hospital, a school, the Swedish Embassy and an organization in order to create an image of different levels in society means to implement preventive measures on HIV and AIDS to their citizens. The result demonstrates that there are clear shortcomings in its implementation guidance on prevention measures for HIV and AIDS as lack of resources is based.

Since the end of the eighteenth century forest damage caused by the pathogen Gremmeniella abietina has been observed and documented. During the latest Epidemic in Sweden more than 480 000 hectares forest land have been injured and this has lead to considerable economic losses. For the pathogen to succeed with infection, spore dispersal and colonization the right environmental conditions is required. The aim of this paper is to describe the diseased stands using site and stand characteristics and to evaluate the effect of these variables on the disease incidence. Further, the thinning performed during the time for spore dispersal and its relationship to injured stands is examined.

Salmonella in cats has been documented for many years. Infection with S. Typhimurium,which is often referred to as Songbird fever, is believed to be caused by birds whoinadvertently infect cats. The disease is often seen during the springtime when songbirdsreturn from their winter habitats, while other birds who have stayed during the winter are intheir weakest condition of health. In the spring of 1999 an Epidemic of S.

The virus-mediated disease Rift Valley fever (RVF) was discovered during an outbreak in Kenya in the 1930s. Since then it has spread to most parts of Sub-Saharan Africa, and in the last decades several outbreaks have caused economic and health issues in Africa, Yemen and Saudi-Arabia. The disease mainly affects domestic livestock, causing abortions, but is also a zoonosis. To be able to control the spread of the disease it is important with surveillance for better knowledge about the distribution and virus circulation even in inter-Epidemic/epizootic periods. The human population is growing, and people and their livestock constantly move closer to areas with wild animals which act as reservoirs for different viruses. Also, humans and their animals often get within reach for arthropod vectors, hosting or carrying viruses.

Diabetes mellitus is a rising Epidemic throughout the world and there is currently great interest in quantifying the beta-cell mass (BCM) in vivo non-invasively. In the present experiment, the feasibility of in vivo imaging of the glucagon-like peptide-1 receptor (GLP-1R) in beta-cells was examined, using the positron emission tomography (PET) tracer [68Ga]Ga-DO3A-VS-Cys40-exendin-4 as a marker, in native pancreatic beta-cells of a porcine diabetic animal model and healthy controls. Eight Swedish high-health domestic pigs were randomly assigned to be either controls or made diabetic using streptozotocin (STZ). The experiment proceeded during eight weeks, starting with an acclimatisation period. Once the pigs had been socialised they underwent surgery for the insertion of a jugular vein catheter, allowing induction of diabetes with STZ, intravenous (i.v.) injections and stress-free blood sampling. Development of diabetes was confirmed by clinical examinations, blood glucose values and insulin-staining of pancreatic sections post mortem. The diabetic pigs were insulin treated and responded well.
