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.

The Role of Governmental Credit in Hemispheric Trade [PDF]

, 1941
Ion channels in the plasma membrane are important for the apoptotic process. Different types of voltage-gated ion channels are up-regulated early in the apoptotic process and block of these channels prevents or delays apoptosis.

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.

Synthetic Ion Channels

Langmuir, 2013
The objective of this historical review is to recall the development of the field of synthetic ion channels over the past three decades. The most inspiring and influential breakthroughs with regard to structure and function are brought together to give the general reader an easily accessible understanding of the field.

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 Channels and Migraine [PDF]

Headache: The Journal of Head and Face Pain, 2014
Migraine is one of the most common neurological disorders. Despite its prevalence, the basic physiology of the molecules and mechanisms that contribute to migraine headache is still poorly understood, making the discovery of more effective treatments extremely difficult.

Ion channels and ion selectivity [PDF]

Essays in Biochemistry, 2017
Specific macromolecular transport systems, ion channels and pumps, provide the pathways to facilitate and control the passage of ions across the lipid membrane. Ion channels provide energetically favourable passage for ions to diffuse rapidly and passively according to their electrochemical potential.
