External Mechanical Cardiac Stimulation

New England Journal of Medicine, 1976
TEMPORARY cardiac stimulation in the emergency resuscitation from cardiac arrest and in other less urgent conditions is generally applied by way of a pervenous endocardial electrode and an external...

Stimulation Mechanism and Application

2021
Before a CBM well is put into production, fracturing is often required to induce fractures of a certain height and width in order to improve productivity. In the design of fracture height and width, it is necessary to have an accurate understanding of in-situ stress and coal rock mechanics.

Mechanical stimulation of primary cilia

Frontiers in Bioscience, 2008
The ciliary/flagellar system is perhaps unique in biology in that not only are biochemical manipulations used to elucidate the function, but physical manipulations as well. Thus, there is a considerable need to have an integrated physical-biochemical model of a cilium and its function.

Electro-mechanical cochlear stimulation

Proceedings of the First Regional Conference, IEEE Engineering in Medicine and Biology Society and 14th Conference of the Biomedical Engineering Society of India. An International Meet, 2002
The dynamic range available for the electrical stimulation of the cochlear-impaired ear is very narrow compared to that of acoustic stimulation of the normal ear. The normal frequency resolving mechanism is very much restricted for functional electrical cochlear stimulation.

Mechanisms of thrombin‐stimulated cell division

Journal of Supramolecular Structure, 1979
AbstractAddition of highly purified thrombin t o cultures of several kinds of nondividing fibroblasts brings about cell division. This stimulation occurs in serum‐free medium, permitting studies on its mechanism under chemically defined conditions. Previous studies have shown that action of thrombin a t the cell surface is sufficient to cause cell ...

Mechanical Stimulation of Coughing

AJN, American Journal of Nursing, 1971
The suction created by the machine not only sucks out secretions but it also aspirates oxygen. The use of a catheter that is too large or suction that is too high and the failure to allow the patient time to ventilate between suction attempts also lead to hypoxia. But, there are alternatives to suctioning.

An Acupuncture-like Quantitative Mechanical Stimulator

2005 IEEE Engineering in Medicine and Biology 27th Annual Conference, 2005
A stimulator that analogs the needle puncture has been designed to deliver quantitative mechanical stimulus to a small area of muscle. A friction coupler is designed to transmit the driving force from motor to a needle which is used to deliver stimulus. Rotation of the needle may be stopped but the friction will be maintained between the needle and the

Monoaminergic mechanisms in aversive brain stimulation

Physiology & Behavior, 1975
In these experiments we have examined the role of brain monoamines in the fearlike aversive responses produced by the electrical stimulation of the dorsal midbrain tegmentum (DMT). Chronic bipolar stimulating electrodes were bilaterally implanted into the DMT of 77 rats.

Mechanical Stimulation of Starfish Sperm Flagella

Journal of Experimental Biology, 1976
ABSTRACT The responses of starfish sperm flagella to mechanical stimulation with a microneedle were analysed. Flagellar movement was recorded by high-speed microcinematography and by stroboscopic observation. The amplitude of the bending wave of a flagellum was restricted over its entire length when the microneedle was brought near to ...
