THE PHYSIOLOGY OF BONE BLOOD FLOW

The Journal of Bone and Joint Surgery-American Volume, 2006
Bone circulation plays an important role in bone physiology, but has been relatively poorly studied, because most techniques of circulatory research are difficult to apply to bone. This article summarizes briefly some of the important aspects of the physiology of bone blood flow most relevant to orthopaedics.The gold standard for experimental ...

Flow Structures in Physiological Conduits

2011
The study of topological structures in the case of a peripheral planar bypass graft and a cerebral aneurysm are presented. The Taylor series expansion of the velocity field to first order terms leads to a system of ODEs, the solution to which locally describes the motion of the flow.

The Physiologic Importance of Pulsatile Blood Flow

New England Journal of Medicine, 1962
NOT since the time of Hippocrates has the diagnostic value of the arterial pulse been disputed. Yet its role in physiology is considered of little, if any, consequence. Typical of this attitude was Wesolowski's1 statement that "the presence of the pulse may represent nothing more in physiological terms than an expression of the limitations of the ...

Physiology of Coronary Blood Flow

2015
Coronary blood flow is responsible for providing nutrients and oxygen to the heart thus enabling it to pump blood to itself and the rest of the circulatory system. Given this important task, oxygen supply must be matched very closely to the demands of the myocardium.

Transmural Flow During Physiological Vasodilation

1984
It is well established that coronary blood flow is influenced by 1) metabolic activity of the myocardium and 2) by mechanical forces generated by contracting cardiac muscle. Of course, these factors are interrelated. Usually they are positively correlated with increases in cardiac function associated with increases in myocardial metabolism and with ...

Flow Cytometric Measurement of Different Physiological Parameters

2018
A variety of physiological parameters involved in signal transduction pathways, enzymatic activities, ATP production, and many other physiological processes can be analyzed by flow cytometry. Parameters as intracellular pH, membrane potential, calcium concentration, reactive oxygen species (ROS) generation, or glutathione content can be estimated ...

An Electromechanical Flow Transducer for Physiological Fluids

Physics in Medicine & Biology, 1966
A simple method, based on conductivity measurement, has been developed to obtain an electrical output from a rotameter flowmeter. The ancillary equipment required is relatively simple and inexpensive. The reproducibility of readings throughout the day is generally better than ±2% and never worse than ±5%.

Physiology of Cerebral Blood Flow

Abstract Cerebral blood flow (CBF) is tightly regulated regionally via multiple processes including the neurovascular unit which consists of perivascular nerves, endothelium, and astrocytes working together to regulate CBF, autoregulation which allows the brain to maintain a constant CBF despite changes in blood pressure, flow metabolism

Cerebral Blood Flow Physiology and Monitoring

2004
For optimal therapy of patients with brain injury, a thorough knowledge of the underlying cerebral blood flow (CBF) physiology is essential. This chapter reviews the relationship between CBF and brain metabolism and summarizes the therapeutic implications of this interaction in patients with brain injury.
