A new class of neurotoxin from wasp venom slows inactivation of sodium current
(Blackwell Science, 2000-06-01)
The effects of alpha-pompilidotoxin (alpha-PMTX), a new neurotoxin isolated from the venom of a solitary wasp, were studied on the neuromuscular synapses in lobster walking leg and the rat trigeminal ganglion (TG) neurons. ...
Correlation between charge movement and ionic current during slow inactivation in Shaker K+ channels
(ROCKEFELLER UNIV PRESS, 1997-11)
Prolonged depolarization induces a slow inactivation process in some Ki channels. We have studied ionic and gating currents during long depolarizations in the mutant Shaker H4-Delta(6-46) K+ channel and in the nonconducting ...
The influence of diet on liver phosphorylase. III. Role of inactivation on the decrease of phosphorylase under certain dietary conditions
(1962)
The addition of epinephrine to the incubation medium did not modify significantly and regularly the phosphorylase activity of liver slices prepared from well-fed or fasted rats. Liver phosphorylase was rapidly inactivated ...

(Blackwell Science, 2000-06-01)
The effects of alpha-pompilidotoxin (alpha-PMTX), a new neurotoxin isolated from the venom of a solitary wasp, were studied on the neuromuscular synapses in lobster walking leg and the rat trigeminal ganglion (TG) neurons. ...
A conducting state with properties of a slow inactivated state in a Shaker K+ channel mutant
(ROCKEFELLER UNIV PRESS, 2001-02)
In Shaker K+ channel, the amino terminus deletion Delta6-46 removes fast inactivation (N-type) unmasking a slow inactivation process. In Shaker Delta6-46 (Sh-IR) background, two additional mutations (T449V-I470C) remove ...

Fast elimination of onychomycosis by hematoporphyrin derivative-photodynamic therapy
(Elsevier BVAmsterdam, 2013-09)
Onychomycosis is a fungal nail disease and is one of the major onychopathy worldwide. Topical or oral antifungal therapies are used to treat this disease, but often they are inefficient and oral medications can even cause ...
Efeito diferencial do veneno do escorpião Tityus bahiensis em correntes desódio sensíveis e resistentes a tetrodotoxina em neurônios dos Gânglios daRaiz Dorsal de Ratos.
(Universidade Federal de Minas GeraisUFMG, 2007-08-10)
In this study, we tested the effects of Tityus bahiensis scorpion venom on sodium currents recorded from the cell bodies of rat dorsal root ganglion neurons using the whole-cell patch clamp technique. In control conditions, ...
La anémona de mar Bunodosoma caissarum toxina BcIII modula la cinética actual de sodio de las neuronas de los ganglios de raíz dorsal de rata y es desplazada de forma voltaje dependiente.
(2010)
Toxinas de anémona de mar se unen para 3 de los canales de sodio, que está formado parcialmente por el vinculador extracelular conectando segmentos S3 y S4 del dominio IV, ralentizando el proceso de inactivación. En este ...
