Bisphenol A inhibits voltage-activated Ca(2+) channels in vitro: mechanisms and structural requirements.

André Deutschmann et al.

Molecular pharmacology, 83(2), 501-511 (2012-12-01)

Bisphenol A (BPA), a high volume production chemical compound attracts growing attention as a health-relevant xenobiotic in humans. It can directly bind to hormone receptors, enzymes, and ion channels to become biologically active. In this study we show that BPA

Expression and function of a T-type Ca2+ conductance in interstitial cells of Cajal of the murine small intestine.

Haifeng Zheng et al.

American journal of physiology. Cell physiology, 306(7), C705-C713 (2014-01-31)

Interstitial cells of Cajal (ICC) generate slow waves in gastrointestinal (GI) muscles. Previous studies have suggested that slow wave generation and propagation depends on a voltage-dependent Ca(2+) entry mechanism with the signature of a T-type Ca(2+) conductance. We studied voltage-dependent

Barium distributions in teeth reveal early-life dietary transitions in primates.

Christine Austin et al.

Nature, 498(7453), 216-219 (2013-05-24)

Early-life dietary transitions reflect fundamental aspects of primate evolution and are important determinants of health in contemporary human populations. Weaning is critical to developmental and reproductive rates; early weaning can have detrimental health effects but enables shorter inter-birth intervals, which

Glial role in oxaliplatin-induced neuropathic pain.

Lorenzo Di Cesare Mannelli et al.

Experimental neurology, 261, 22-33 (2014-06-27)

Oxaliplatin, a platinum-based chemotherapeutic agent, has become a standard treatment for advanced colorectal cancer. The dose-limiting toxicity of this compound is the development of peripheral neuropathy. A tangled panel of symptoms, sensory loss, paresthesia, dysesthesia and pain, may be disabling

Basolateral K channels in an insect epithelium. Channel density, conductance, and block by barium.

J W Hanrahan et al.

The Journal of general physiology, 87(3), 443-466 (1986-03-01)

K channels in the basolateral membrane of insect hindgut were studied using current fluctuation analysis and microelectrodes. Locust recta were mounted in Ussing-type chambers containing Cl-free saline and cyclic AMP (cAMP). A transepithelial K current was induced by raising serosal
