Ion permeation in normal and batrachotoxin-modified Na+ channels in the squid giant axon
(1991)
Na+ permeation through normal and batrachotoxin (BTX)-modified squid axon Na+ channels was characterized. Unmodified and toxin-modified Na+ channels were studied simultaneously in outside-out membrane patches using the ...
Cilium-attached and excised patch-clamp recordings of odourant-activated Ca-dependent K channels from chemosensory cilia of olfactory receptor neurons
(2004)
It has previously been proposed that a Ca2+-dependent K + conductance is implicated in the inhibitory odourant response in rat and toad olfactory receptor neurons. Previous whole-cell and single-channel measurements on ...
Dissemination, sharing and appropriation of information on YouTube: an analysis of the LGBTQ channel Ptie na Roda
(Univ Federal Santa Catarina, 2020-01-01)
Objective: When working with the social and historic context of Lesbian, Gay, Bisexual, Transgender and Queer (LGBTQ) people, it is possible to see the existence of several dimensions of visibility in physical and virtual ...
Mouse sperm patch-clamp recordings reveal single Cl- channels sensitive to niflumic acid, a blocker of the sperm acrosome reaction
(1998)
Ion channels lie at the heart of gamete signaling. Understanding their regulation will improve our knowledge of sperm physiology, and may lead to novel contraceptive strategies. Sperm are tiny (~ 3 μm diameter) and, until ...
Repressor element-1 silencing transcription/neuron-restrictive silencer factor is required for neural sodium channel expression during development of Xenopus
(2002)
The ability of neurons to fire rapid action potential relies on the expression of voltage-gated sodium channels; the onset of the transcription of genes that encode these channels occurs during early neuronal development. ...
Non-selective cation channels and oxidative stress-induced cell swelling
(Society of Biology of Chile, 2002)
Necrosis is considered as a non-specific form of cell death that induces tissue inflammation and is preceded by cell swelling. This increase in cell volume has been ascribed mainly to defective outward pumping of Na+ caused ...
Sodium pathway markers in normal and kindled frog brains
(Elsevier, 1986)
The present report evaluates Na,K-ATPase activity as well as Na channel levels in the frog telencepha-
Ion after kindling, i.e. the acquisition of an epileptic focus through localized low-voltage electrical stimulation
of ...
Novel wasp toxin discriminates between neuronal and cardiac sodium channels
(Amer Soc Pharmacology Experimental Therapeutics, 2001-06-01)
Pompilidotoxins (PMTXs), derived from the venom of solitary wasp has been known to facilitate synaptic transmission in the lobster neuromuscular junction, and a recent further study from rat trigeminal neurons revealed ...
