Multiple Thresholds in a Model System of Noisy Ion Channels [PDF]
, 2006 Voltage-activated ion channels vary randomly between open and closed states, influenced by the membrane potential and other factors. Signal transduction is enhanced by noise in a simple ion channel model.

Effect of channel block on the spiking activity of excitable membranes in a stochastic Hodgkin-Huxley model [PDF]
, 2004 The influence of intrinsic channel noise on the spontaneous spiking activity of poisoned excitable membrane patches is studied by use of a stochastic generalization of the Hodgkin-Huxley model.

Calcium-permeable ion channels in control of autophagy and cancer
Frontiers in Physiology, 2013 Autophagy, or cellular self-eating, is a tightly regulated cellular pathway the main purpose of which is lysosomal degradation and subsequent recycling of cytoplasmic material to maintain normal cellular homeostasis.

Structure and permeability of ion-channels by integrated AFM and waveguide TIRF microscopy. [PDF]
, 2014 Membrane ion channels regulate key cellular functions and their activity is dependent on their 3D structure. Atomic force microscopy (AFM) images 3D structure of membrane channels placed on a solid substrate.

Annual Review of Biophysics, 2023 Mitochondria are involved in multiple cellular tasks, such as ATP synthesis, metabolism, metabolite and ion transport, regulation of apoptosis, inflammation, signaling, and inheritance of mitochondrial DNA. The majority of the correct functioning of mitochondria is based on the large electrochemical proton gradient, whose component, the inner ...

P2X receptors: epithelial ion channels and regulators of salt and water transport. [PDF]
, 2008 When the results from electrophysiological studies of renal epithelial cells are combined with data from in vivo tubule microperfusion experiments and immunohistochemical surveys of the nephron, the accumulated evidence suggests that ATP-gated ion ...

Ion channel activity drives ion channel expression [PDF]
The Journal of Physiology, 1998 During embryonic development, excitable cells acquire a repertoire of ion channels that finely tune their electrical properties. Although the mechanisms by which an excitable cell selects its complement of ion channels are poorly defined, cell-autonomous as well as non-autonomous programmes of differentiation have been implicated.

Evolving theoretical descriptions of heavy-ion fusion :from phenomenological to microscopic approaches [PDF]
, 2017 We overview the current status of theoretical approaches for heavy-ion fusion reactions at subbarrier energies. We particularly discuss theoretical challenges in the coupled-channels approach, that include i) a description of deep subbarrier hindrance of

Circulation: Arrhythmia and Electrophysiology, 2009 The analysis of the molecular basis of the inherited cardiac arrhythmias has been the driving force behind the identification of the ion channels that generate the action potential. The genes encoding all the major ion channels have cloned and sequenced. The studies have revealed greater complexity than heretofore imagined.
