Neural Mechanisms of Spinal Cord Stimulation
2012Neuromodulation, specifically spinal cord stimulation (SCS), relieves pain and improves organ function. This chapter discusses the limited information presently available about the underlying mechanisms that explain the beneficial effects of treating patients with SCS.

Mechanism for cardiac stimulation during hypoxia
American Journal of Physiology-Legacy Content, 1965In isolated guinea pig atria, hypoxia was induced by bubbling nitrogen through Tyrode solution. A significant increase in both the amplitude and frequency of the contractions occurred, followed by a decrease. Average rate in 11 control atria was 138 ± 9.2 contractions/min and increased during hypoxia by an average value of 12.7 ± 2.3 contractions/min (

Mechanism of polycation stimulation of pinocytosis
Biochimica et Biophysica Acta (BBA) - General Subjects, 1979Synthetic polycations cause a stimulation in the rate of tissue accumulation of colloidal 198Au by the rat visceral yolk sac (at 17.5 days of gestation) and rat peritoneal macrophages cultured in vitro. The mechanism of stimulation has been elucidated in these two cell types by using a dual-substrate technique, and by examining the differential effects

Monoaminergic mechanisms of stimulation-produced analgesia
Pain, 1975The roles played by the cerebral monoamines (dopamine, noradrenaline and serotonin) in stimulation-produced analgesia (SPA) have been investigated in the rat employing the tail flick test. SPA was elicited through bipolar electrodes chronically implanted in the mesencephalic periaqeductal gray matter, an area previously shown to yield potent and ...

Therapeutic mechanisms of vagus nerve stimulation
Neurology, 2002Experiments in acute and chronic animal models of epilepsy provide mechanistic insight into the acute abortive, acute prophylactic, and chronic progressive prophylactic, anti-seizure effects of vagus nerve stimulation (VNS) observed in human epilepsies, and demonstrate antiepileptogenic effects of VNS in the kindling model. Anatomic-physiologic studies,

Arteriogenesis: basic mechanisms and therapeutic stimulation
European Journal of Clinical Investigation, 2007AbstractPharmacological attempts to stimulate the growth of collateral arteries (arteriogenesis) are evolving towards a new treatment option for patients with vascular occlusive diseases. This enlargement of small pre‐existing anastomoses towards large conductance arteries takes place independent of local oxygen tension and is driven by changes in ...

Mechanisms of Respiratory Stimulation During Hemorrhage
American Journal of Physiology-Legacy Content, 1957The immediate effects of severe hemorrhage on respiratory rate and amplitude were determined in dogs before and after bilateral vagotomy and isolation of the carotid sinuses. The animals were anesthetized with morphine (3 mg/kg) intramuscularly and sodium pentobarbital (15 mg/kg) intravenously.

Control Mechanisms and Stimulation
1980The introduction during recent years of radioimmunoassay methods has led to a considerable increase in our knowledge of the importance of thyroid and pituitary hormones in influencing the growth and function of thyroid tumours derived from the follicular cells.

Mechanism of Ethanol‐Induced Adrenal Stimulation
Alcoholism: Clinical and Experimental Research, 1982A historical review of studies addressing the adrenal cortical response to ethanol and the mechanisms thought to contribute to such responses is presented. Studies reviewed range from the earliest based upon crude bioassay techniques to more modern papers which have utilized highly specific radioimmunoassay techniques and isolated perfused rat adrenal ...

Game Theoretic Stimulation Mechanisms
2015Cognitive radio networks are vulnerable to a wide range of attacks such as jamming and selfish attacks. To achieve efficient and robust resource management and suppress behavior of selfish or malicious users, users’ behaviors and dynamics have to be taken seriously into consideration.
