The diagnosis of malignant hyperthermia is currently performed with the in-vitro contracture test (IVCT) with halothane and caffeine. This test has a sensitivity of 99.0 % but only a specificity of 93.6 %. A cumulative IVCT with 4-chloro-3-ethyl-phenole (CEP) has
The ultrafast extraocular muscles necessitate tight regulation of free cytosolic Ca2+ concentration ([Ca2+]i). Mitochondrial Ca2+ influx may be fast enough for this role. In the present study, three hypotheses were tested: (1) Mitochondrial Ca2+ uptake regulates [Ca2+]i and production of

Depletion of the Ca(2+) store by ryanodine receptor (RyR) agonists induces store-operated Ca(2+) entry (SOCE). 4-Chloro-3-ethylphenol (4-CEP) and 4-chloro-m-cresol (4-CmC) are RyR agonists commonly used as research tools and diagnostic reagents for malignant hyperthermia. Here, we investigated the effects of

The in vitro contracture test with halothane and caffeine is the current gold standard for diagnosis of malignant hyperthermia. This test has a sensitivity of 99.0% but a specificity of only 93.6%. Therefore, an alternative drug is desirable which distinguishes

1. Recently, 4-chloro-3-ethyl phenol (CEP) has been shown to cause the release of internally stored Ca2+ apparently through ryanodine-sensitive Ca2+ channels, in fractionated skeletal muscle terminal cisternae and in a variety of non-excitable cell types. Its action on smooth muscle
