Fractal Rigidity in Migraine
We study the middle cerebral artery blood flow velocity (MCAfv) in humans using transcranial Doppler ultrasonography (TCD). Scaling properties of time series of the axial flow velocity averaged over a cardiac beat interval may be characterized by two exponents. The short time scaling exponent (STSE) determines the statistical properties of fluctuations of blood flow velocities in short-time int...
متن کاملMigraine versus probable migraine.
CLINICAL HISTORY A 77-year-old man has a history of similar recurring headaches since he was a teenager. For years, the headaches would occur about one time per month, but for the last 5 years, they occur about once per week. He reports a left frontal-retro-orbital aching non-throbbing pain without associated aura, nausea, vomiting, and light or noise sensitivity. Untreated headaches can last 1...
متن کاملStudies in Ocular Rigidity.
RECENT developments in tonography and applanation tonometry have caused greater attention to be focused on the relation of the elastic properties of the coats of the eye and of ocular rigidity to the intra-ocular pressure. It is now fairly well established that the coefficient of ocular rigidity, K, is not a constant, as Friedenwald (1937) had suggested, but that it varies with the intra-ocular...
متن کاملRigidity in Solids
We address the question of whether solids may be distinguished from fluids by their response to shear stress.
متن کاملHelicobacter pylori and Migraine: Is Eradication of Helicobacter pylori Effective in Relief of Migraine Headache?
