11. Nuclear magnetic resonance and microcirculation: The influence of pulsatile brain-tissue motion on measurements of intravoxel incoherent motion and assessment of haemodynamics using exo- and endogenous tracers
Abstract : In this project, the potential of magnetic resonance (MR) imaging and spectroscopy in studies of microcirculation and haemodynamics was evaluated. The spatial and temporal characteristics of human pulsatile brain-tissue movements in healthy individuals, relevant for the understanding of the cerebrospinal-fluid (CSF) circulation and the pathogenesis of hydrocephalus, were thoroughly investigated.

12. Metabolic effects of interleukin-6
Abstract : The levels of the cytokine interleukin-6 (IL-6) in the circulation are positively correlated with indices of obesity and metabolic disturbances. Paradoxically, plasma IL-6 levels increase markedly during prolonged and strenuous exercise, mainly due to increased production and release from working skeletal muscle. READ MORE

13. Flux of cholesterol, oxysterols and plant sterols across the blood-brain barrier and metabolic consequences
Abstract : Brain is the cholesterol-richest organ and contains one fourth of the total body cholesterol. The majority of brain cholesterol is present in myelin that forms myelin sheathes around neuronal axons. This large pool of cholesterol present in brain is separated from body cholesterol by the blood brain barrier (BBB). READ MORE

14. Studies on oxysterols : origins, properties and roles
Abstract : Oxysterols are derivatives of cholesterol present at low concentrations in a variety of physiological compartments. The major oxysterols in human circulation are formed from pools of cholesterol that may be distinguished by their miscibility with plasma cholesterol. READ MORE

15. Chemotactic factors in the human follicle at ovulation
Abstract : Ovulation is initiated by the midcycle gonadotropin surge, which leads to a controlled degradation of the follicle wall ending in follicular rupture and oocyte extrusion. The gonadotropins triggers several biochemical and biophysical changes such as vascular alterations, increased proteolytic enzyme activity and leukocyte extravasation, within the preovulatory follicle.
