Nicotinic acetylcholine receptors containing the α7-like subunit mediate contractions of muscles responsible for space positioning of the snail, Helix pomatia L. tentacle. [PDF]

open access: yesPLoS ONE, 2014
Three recently discovered tentacle muscles are crucial to perform patterned movements of upper tentacles of the terrestrial snail, Helix pomatia. The muscles receive central and peripheral excitatory cholinergic innervation lacking inhibitory innervation.

Mechanical influences on morphogenesis of the knee joint revealed through morphological, molecular and computational analysis of immobilised embryos. [PDF]

open access: yesPLoS ONE, 2011
Very little is known about the regulation of morphogenesis in synovial joints. Mechanical forces generated from muscle contractions are required for normal development of several aspects of normal skeletogenesis.

Conductance increases produced by bath application of cholinergic agonists to Electrophorus electroplaques [PDF]

open access: yes, 1975
When solutions containing agonists are applied to the innervated face of an Electrophorus electroplaque, the membrane's conductance increases. The agonist-induced conductance is increased at more negative membrane potentials.

The role of embryo movement in the development of the furcula [PDF]

open access: yes, 2017
The pectoral girdle is a complex structure which varies in its morphology between species. A major component in birds is the furcula, which can be considered equivalent to a fusion of the paired clavicles found in many mammals, and the single ...

A covalently bound photoisomerizable agonist. Comparison with reversibly bound agonists at electrophorus electroplaques [PDF]

open access: yes, 1980
After disulphide bonds are reduced with dithiothreitol, trans-3-(alpha-bromomethyl)-3’-[alpha-(trimethylammonium)methyl]azobenzene (trans-QBr) alkylates a sulfhydryl group on receptors.

GABA\u3csub\u3eA\u3c/sub\u3e and excitatory amino acid receptors in dorsomedial hypothalamus and heart rate in rats [PDF]

open access: yes, 1991
We have previously shown that microinjection of drugs that interfere with the function of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) into the hypothalamus produces cardiorespiratory and behavioral changes resembling those seen in ...

Sarcoplasmic Reticulum K+ (TRIC) Channel Does Not Carry Essential Countercurrent during Ca2+ Release [PDF]

open access: yes, 2013
The charge translocation associated with sarcoplasmic reticulum (SR) Ca2+ efflux is compensated for by a simultaneous SR K+ influx. This influx is essential because, with no countercurrent, the SR membrane potential (Vm) would quickly (
