adenosine triphosphate/headache

We encountered a 10-year-old girl with fluctuating sensorineural hearing loss, episodic headache, and white matter stroke. Strenuous exercise, febrile illness, and general anesthesia all temporarily worsened hearing. Audiologic findings were asymmetric: left-sided retrocochlear dysfunction

We used phosphorus magnetic resonance spectroscopy to assess in vivo the brain cytosolic free magnesium concentration and the free energy released by the reaction of adenosine triphosphate (ATP) hydrolysis (DeltaG(ATPhyd)), the latter being an index of the cell's bioenergetics condition. We studied

Introduction The trigeminal ganglion is unique among the somatosensory ganglia regarding its topography, structure, composition and possibly some functional properties of its cellular components. Being mainly responsible for the sensory innervation of the anterior regions of the head, it is a major

Classical migraine is associated with two distinct phases; an initial vasoconstriction followed by vasodilatation. The "purinergic" hypothesis for migraine was originally put forward in 1981 as a basis for the reactive hyperaemia and pain during the headache phase. It was suggested that adenosine

ATP-sensitive potassium (K_ATP ) channel opener levcromakalim induces migraine attacks in migraine patients. Underlying mechanisms responsible for headache and migraine induction after levcromakalim infusion are unknown.

To investigate the

OBJECTIVE To determine the degree of diagnostic and clinical similarity between chronic sympathetic nervous system disorders and migraine. BACKGROUND Migraine is an episodic syndrome consisting of a variety of clinical features that result from dysfunction of the sympathetic nervous system. During

Bedaquiline is a diarylquinoline antitubercular drug with a novel mechanism of action against Mycobacterium tuberculosis. Bedaquiline works by inhibiting bacterial adenosine triphosphate (ATP) synthase and represents the first novel class of antituberculosis agents in more than 40 years. Bedaquiline

BACKGROUND Nateglinide, N-(trans-4-isopropylcyclohexyl-carbonyl)-d-phenylalanine, is a potent insulin secretagogue designed to restore early-phase insulin secretion. It increases pancreatic insulin secretion by competitively binding to sulfonylurea receptors inhibiting adenosine

Openers of adenosine triphosphate (ATP)-sensitive potassium channels relax vascular smooth muscle and protect ischemic myocardium. Cromakalim and BMS-180448 are examples of this class of compounds. They are equipotent in their cardioprotective activity, but cromakalim and related compounds are

Levosimendan is one of the first agents of a new class of drugs known as calcium sensitizers. These drugs are believed to increase cardiac contractility by sensitizing cardiac myofibrils to calcium, and may therefore be of clinical benefit in the treatment of low-cardiac output states, particularly

Caffeine acts as a stimulant, in which approximately 90% of people in the United States consume daily. Besides its beneficial effects, many individuals have experienced unpleasant reactions following the consumption of caffeine: such as insomnia, an increase in heart rate, feelings of nervousness,

Electrolytes are essential for basic life functioning such as maintaining electrical neutrality in the cells, generation, and conduction of action potentials in the nerves and muscles. Sodium, potassium, and chloride are the significant electrolytes along with magnesium, calcium, phosphate, and

Garcinia cambogia contains hydroxycitric acid. Hydroxycitric acid is a potent competitive inhibitor of adenosine triphosphate citrate lyase which is a key enzyme in the synthesis of fatty acids. Hydroxycitric acid also regulates the level of serotonin. In these

Background: Adenosine triphosphate (ATP) and glutamate are associated with some headache conditions, and purinergic (P2X) and glutamatergic N-methyl-D-aspartate (NMDA) receptor-related processes in the medulla can modulate the effects of

UNASSIGNED Central nervous system-derived interleukin-1β plays a role in mood disorders. P2X7 receptor activation by adenosine-triphosphate leads to the release of interleukin-1β. UNASSIGNED This first-in-human study evaluated safety, tolerability, pharmacokinetics and pharmacodynamics of a novel
