In this study, hydrogen was recovered and purified by using a membrane contactor unit from CO2-rich gas without the use of any basic chemicals such as amines. The operational parameters were adjusted to achieve high CO2 removal H2 recovery. effects flow rate, pressure, composition (CO2/H2 ratio), pressure difference between liquid gas, gas/liquid ratio on recovery investigated. Depending contac...

Capsaicin and other naturally occurring pungent molecules have long been used as topical analgesics to treat a variety of chronic pain conditions. The analgesic effects of these compounds involve long-term desensitization of nociceptors after strong stimulation. To elucidate the underlying mechanisms, we studied the recovery from desensitization of the vanilloid receptor TRPV1. We showed that p...

The human ether-a-go-go related gene (hERG) encodes the pore-forming subunit of the rapidly activating delayed rectifier potassium channel (IKr). A reduction in the hERG current causes long QT syndrome, predisposing affected individuals to a high risk of cardiac arrhythmias and sudden death. We previously reported that hERG channels in the plasma membrane undergo internalization under low K con...
