5 Brain metabolism and cerebral blood flow

Cerebral blood flow is influenced and regulated by a number of factors, including arterial blood pressure, intracranial pressure, venous outflow, blood viscosity, PaCO2 and PaO2, collateral flow, vasoreactivity and the status of cerebral autoregulation. The regulation of vascular resistance lies mainly in the arterioles and precapillary segments (Auer and Loew, 1983). It is important to note th...

The Causes of Resistance to Change and Solutions to Overcome It: A Review of Literature

Introduction: Technological advances as well as science and information explosion necessitate the change in students’ educational needs and in the education system. Researchers consider resistance to change as one of the major causes of the failure of changes. Therefore, the purpose of this review study was to identify the causes of resistance to change and provide solutions to overcome it. Met...

Abnormal cerebral blood flow in methamphetamine abusers assessed by brain perfusion single emission computed tomography

Introduction:Amphetamines are central nervous system (CNS) stimulant substances and amphetamine abuse is considered a growing problem in our country. Previous studies revealed destructive effects of amphetamines on metabolism, perfusion and structure of brain. The aim of current study was evaluating regional cerebral blood flow (rCBF) disturbances in methamphetamine (MA) abuser...

Cerebral blood flow in takotsubo syndrome: is it specific for the disease?

To The Editor: I read with great interest the contribution by Suzuki et al, published online on November 28, 2013 ahead of print in the Journal,1 about the assessment of cerebral blood flow (CBF) in 3 consecutive patients with Takotsubo syndrome (TTS) and at follow-up, when myocardial function had recovered. This is the first evidence that CBF, and indirectly brain activity, is enhanced in the ...
