Inhibition of post-synaptic Kv7/KCNQ/M channels facilitates long-term potentiation in the hippocampus. [PDF]

PLoS ONE, 2012
Activation of muscarinic acetylcholine receptors (mAChR) facilitates the induction of synaptic plasticity and enhances cognitive function. In the hippocampus, M(1) mAChR on CA1 pyramidal cells inhibit both small conductance Ca(2+)-activated KCa2 ...

Soft Mechanical‐Electrical Logic Using Liquid Metal‐Filled 3D‐Printed Architectures

Advanced Engineering Materials, EarlyView.
We present 3D‐printed soft mechanical–electrical logic elements that use liquid metal–filled silicone tubes actuated by thermoplastic polyurethane/polylactic acid (TPU/PLA) architectures to produce Boolean operations. Complementary normally open and normally closed unit cells perform repeatable binary transitions and can be combined into more complex ...

Excitability of jcBNST neurons is reduced in alcohol-dependent animals during protracted alcohol withdrawal. [PDF]

PLoS ONE, 2012
Alcohol dependence and withdrawal has been shown to cause neuroadaptive changes at multiple levels of the nervous system. At the neuron level, adaptations of synaptic connections have been extensively studied in a number of brain areas and accumulating ...

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

‘Dynamic clamp’ in cardiac electrophysiology

The Journal of Physiology, 2005
In the recent study ‘Role of the transient outward current (Ito) in shaping canine ventricular action potential – a dynamic clamp study’ by Sun & Wang (2005), the authors used the ‘dynamic clamp’ technique to inject a computer-calculated current into an isolated ventricular myocyte under current-clamp conditions, thus simulating an ion channel ...

Dynamical flexibility of damped vibratory clamped‐clamped beam in transportation [PDF]

PAMM, 2010
AbstractThis work concerns the issue of damped vibratory beam in transportation. Support conditions were defined for clamped‐clamped beamlike systems. Structural loads were defined as with unitary amplitude ones up to the used dynamical flexibility definition.

Antilipolytic Insulin Sensitivity Indices Measured during an Oral Glucose Challenge: Associations with Insulin-Glucose Clamp and Central Adiposity in Women without Diabetes [PDF]

Endocrinology and Metabolism
Background Tissue overexposure to non-esterified fatty acids (NEFA) contributes to the development of metabolic conditions, with insulin-mediated suppression of lipolysis being an important mechanism in limiting this overexposure.

Texoskeletons: Developing the Fundamental Technologies for Creating Intelligent Soft Robotic Clothing With Integrated 1D Sensors and Actuators

Advanced Functional Materials, EarlyView.
ABSTRACT Traditional wearable exoskeletons rely on rigid structures, which limit comfort, flexibility, and everyday usability. This work introduces the fundamental technologies to create the first soft, lightweight, intelligent textile‐based exoskeletons (Texoskeletons) built using 1D sensors and actuators.

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

Advanced Functional Materials, EarlyView.
The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

Glissile Interphase Boundaries Enable Collective Phase Switching in Epitaxial Polar Oxides

Advanced Functional Materials, EarlyView.
A triple point is identified in the phase diagram of low‐symmetry epitaxial BiFeO3 thin film along with an extended regime of phase competition associated with a flattened energy landscape. The electromechanical response is shown to be governed by correlated interphase‐boundary motion, including scale‐free avalanche dynamics characteristic of systems ...
