Av flera viktiga skäl borde Margot Wallström ha avstått från mötet med Irans utrikesminister Mohammad Javad Zarif. Islamiska regimen har redan tillräckligt många forum för att driva sin politiska agenda. När mötet ändå äger rum måste Wallström lyfta fram viktig kritik, skriver Arvin Khoshnood och Ardavan Khoshnood.

Toothed whales (Odontocetes) use echolocation to navigate and find food in dark or murky waters. A wide range of innovative studies has since the 1960:s been used to characterize their echolocation beam and map out their echolocation skills. In order to render high quality recordings of the sounds emitted by these animals, advanced measurement systems are required. There are still interesting env

BACKGROUND: Exposure to airborne particles in occupational environments can lead to both acute and long-term health effects in humans. To date, particle exposure limits in the air are typically given in terms of mass concentrations. But by only using mass concentration to characterize particles means there is a risk that other relevant characteristics, such as particle size and composition are con

This thesis focuses on the healing and remodeling of the morselized and impacted bone allograft, commonly used in revision of loosened hip prostheses with osteolysis. The influence on remodeling by the impaction procedure per se was analyzed, as well as the effects of endogenous bone graft proteins, and an exogenously applied growth factor (OP-1). A bone chamber model in rats was used, with the in

The ability of many pathogenic microorganisms to cause infection is dependent on their ability to evade attack by the complement system of the host. One mechanism by which microorganisms may avoid complement attack is to bind complement inhibitory molecules present in the host. This thesis describes studies of the complement inhibitor C4BP and of inter-actions between C4BP and the human pathogen

Seasonal Affective Disorder with depressive episodes during the autumn/winter seasons (winter depression) is common. Outpatients with winter depression were studied regarding temperament, psychopathology, social characteristics, psychosocial functioning and the neuropeptides corticotropin - releasing hormone (CRH) and neuropeptide Y (NPY), which are known to be involved in stress-regulation. The t

The method of microdialysis has been adapted for ocular use. It is a technique for monitoring concentrations of different molecules in a tissue in vivo. It is based on the principle of diffusion through a semipermeable membrane. The membrane is mounted on a soft plastic shaft, connected to an inlet and an outlet tube. The whole device, called microdialysis probe, was implanted into the vitreous bo

Biotechnological processes offer environmentally friendly and sometimes cost-effective alternatives to traditional chemical and mechanical methods. It is important to take advantages of the opportunities these processes provide to fulfil the demands and expectations of a future environmentally sustainable society. This work exploits the possibilities of applying biotechnological methods to allow r

Hepatitis B virus is a non-cytopathic virus with a small, circular, partially double-stranded DNA of 3.2 kb. It causes acute and chronic inflammatory liver disease and hepatocellular carcinoma (HCC). Retesting of stored sera from an outbreak of acute hepatitis in 1969-72 allowed identification of 126 cases of acute hepatitis B. No chronic carriers expressing hepatitis B surface antigen (HBsAg) cou

Bread products are one of the most common and important foods in our daily diet, and have been since ancient times. Although it has a long history and comes in many variations, the staling phenomenon of bread is still not fully known. Staling is a complex phenomenon that includes all the physical and sensorial changes occurring in bread during storage. To gain a better understanding of staling, di
