    Sammanfattning : Cobalamin (vitamin B12) is one of several essential micronutrients needed by the human organism. Other important micronutritients, which interplay with vitamin B12, are folate and iron.

    Sammanfattning : The evolution of the human deficiency virus (HIV) field is unparalleled in the history of infectious diseases. From the first cases in the beginning of the 1980s, when an HIV diagnosis was a death sentence, through the discovery of the first effective medicines, up till today when people living with HIV (PLHIV) with access to antiretroviral therapy (ART) can lead a near normal life.

    Sammanfattning : An elevated plasma level of homocysteine has been suggested as a risk factor for cardiovascular disease. The objectives of this thesis were to study the influence of renal function on homocysteine levels in patients with coronary artery disease and to explore the association of elevated plasma levels of homocysteine to oxidative stress, inflammation, and endothelial dysfunction.
