We use gauge theory/string theory correspondence to study the bulk viscosity of strongly coupled, mass deformed SU(Nc) N = 4 supersymmetric Yang-Mills plasma, also known as N = 2 gauge theory. For a wide range of masses we confirm the bulk viscosity bound proposed in [1]. For a certain choice of masses, the theory undergoes a phase transition with divergent specific heat cV ∼ |1 − Tc/T |−1/2. W...

BACKGROUND Diagnosis of giant cell arteritis (GCA) is based on criteria of the American College of Rheumatology. However, not all GCA patients meet these criteria and treatment may be delayed in individual patients, leading to an increased risk of complications. METHODS In an observational study, we investigated acute phase response markers in GCA and non-GCA patients matched for erythrocyte ...

Fluorescein transit tkne from pial arterioles to pial venules was measured in the mouse by analyzing motion pictures taken at 40 frames/sec. Increased blood pressure reduced the transit time. Increased blood viscosity lengthened the transit time. Viscosity was increased by rendering the animals polycythemic, or by infusions of high molecular weight dextran. Two different dexrrans were used. The...

Blood viscosity is a crucial hemodynamic biomarker because it determines the friction against blood vessels, the quantity of oxygen that is delivered to organs and tissues, and the degree of exertion by the heart. Many factors affect blood viscosity, either directly or inversely. e.g., fibrinogen and hematocrit. The effect of other factors (e.g., cholesterol) on blood viscosity is still under i...
