Physiologic basis of potentials recorded in electromyography

Muscle & Nerve, 2000
The extracellularly recorded configuration of a single muscle fiber discharge is generally appreciated to be triphasic with an initially positive deflection. However, careful attention to waveform appearance during the electrodiagnostic medicine examination reveals that both innervated and denervated muscle waveforms may display a pantheon of ...

Melanopsin: photoreceptors, physiology and potential

Current Opinion in Physiology, 2018
The discovery of melanopsin-expressing photosensitive retinal ganglion cells (pRGCs) has led to a fundamental change in our understanding of retinal light detection. pRGCs perform a broad range of non-visual functions — most notably mediating circadian entrainment to the environmental light/dark cycle.

The potential relevance of cytokines to ovarian physiology

The Journal of Steroid Biochemistry and Molecular Biology, 1992
Elucidating the secrets of intraovarian intercellular communication constitutes a central area of investigation. While most attention has been directed thus far at the somatic cellular components of the ovary, the potential role(s) and relative importance of the resident ovarian white blood cell have received relatively limited attention.

Preoxygenation: Physiologic Basis, Benefits, and Potential Risks

Anesthesia & Analgesia, 2017
Preoxygenation before anesthetic induction and tracheal intubation is a widely accepted maneuver, designed to increase the body oxygen stores and thereby delay the onset of arterial hemoglobin desaturation during apnea. Because difficulties with ventilation and intubation are unpredictable, the need for preoxygenation is desirable in all patients ...

Physiological mechanisms underlying long-term potentiation

Trends in Neurosciences, 1988
Abstract In 1949, D. O. Hebb suggested a synaptic modification for learning and memory that occurs as a consequence of coincidence between pre- and post-synaptic activity 1 . This concept has gained wide acceptance and is often used, in its original or modified form, in neuronal net models dealing with learning and memory 2 .

PHYSIOLOGY AND THERAPEUTIC POTENTIAL OF INHIBIN

2020
Post-menopausal women experience adverse changes to the musculoskeletal, metabolic and reproductive systems, resulting from the loss of ovarian hormones (inhibin and oestrogen). Whilst the consequence of oestrogen loss is well-defined, the exact consequence of inhibin loss is unknown. This thesis developed a mouse model of inhibin deficiency, and found

Finding physiological responses in vestibular evoked potentials

2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011
Vestibular prostheses are regarded as a promising tool to restore lost sensation in patients with vestibular disorders. These prostheses often electrically stimulate the vestibular nerve and stimulation efficacy is evaluated by measuring the vestibulo-ocular reflex (VOR).

The Correlation of Human Gastric Potentials with Gastric Physiology

Gastroenterology, 1955
The electrogastrogram (EGG) has been studied by others (1-3) to diagnose gastric disease, but the physiologic significance of gastric potentials so measured is not established. Investigations restricted to experimental animals (4-7) have suggested that these potentials are produced by 1) the degree of acidity of gastric juice, and 2) the electric ...

Copper–homocysteine complexes and potential physiological actions

Journal of Inorganic Biochemistry, 2003
During the last 2 decades it was proposed that atherogenesis was closely related to the homeostasis of homocysteine (hCys) and/or copper. We hypothesized that the physiological action of hCys may be connected with its ability to form complexes with Cu. Our results showed the presence of two different Cu-hCys complexes.

Physiological, pathological and potential therapeutic roles of adipokines

Drug Discovery Today, 2012
Formerly regarded purely as passive energy storage, adipose tissue is now recognized as a vital endocrine organ. Adipocytes secrete diverse peptide hormones named adipokines, which act in a autocrine, paracrine or endocrine way to influence several biological functions.
