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.

Synthesis and structural characterization of Zn-containing DAF-1 [PDF]

open access: yes, 2016
A study exploring the use of ionic liquid reactions based on imidazolium halides in molecular sieve synthesis has produced a novel zincoaluminophosphate material with an open DFO-type framework structure.

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 (

Histochemical demonstration of three types of muscle fibers of the intercostal muscles. A study on oxidative enzymes [PDF]

open access: yes, 1963
Since the classic work of Ranvier, it is well known that the mammalian striated muscle is composed of two types of muscle fibers, i. e., the red and white muscle fibers.

Histochemical studies on the red, white and intermediate muscle fibers of some skeletal muscles. Ⅲ. Histochemical demonstration of oxidative enzymes, phosphorylase and glycogen in respiratory muscle fibers [PDF]

open access: yes, 1966
1) Three different types of muscle fibers were clearly distinguished in the intercostal muscles and the diaphragm of human, cat and rat by histochemical demonstration of oxidative enzymes, phosphorylase and glycogen.

原著 [PDF]

open access: yes, 2016
摘出ラット上頸交感神経節を用いて,刺激頻度と薬物作用との関係を検討し,次の結果を得た。1.Hexamethonium,d-Tubocurarine,PhysostigmineおよびParaoxon作用下では,神経節伝達抑制作用が低頻度刺激よりも高頻度刺激により増強された。このような薬物効果をType Aとした。2.Adrenaline(Adr.),Nor-Adrenaline(Nor-Adr),MgCl_2,MnCl_2ならびにCa^-deficit Ringer(0.1〜0.4mM CaCl_2)では,

Tonic and bursting activity in the cuneate nucleus of the chloralose-anesthetized cat [PDF]

open access: yes, 1998
[Abstract] Whole-cell recordings were obtained from cuneate neurons in anesthetized, paralysed cats. Stimulation of the contralateral medial lemniscus permitted us to separate projection cells from presumed interneurons.

Dual Binding Site and Selective Acetylcholinesterase Inhibitors Derived from Integrated Pharmacophore Models and Sequential Virtual Screening

open access: yesBioMed Research International, Volume 2014, Issue 1, 2014., 2014
In this study, we have employed in silico methodology combining double pharmacophore based screening, molecular docking, and ADME/T filtering to identify dual binding site acetylcholinesterase inhibitors that can preferentially inhibit acetylcholinesterase and simultaneously inhibit the butyrylcholinesterase also but in the lesser extent than ...

Multinuclear Solid-State Magnetic Resonance as a Sensitive Probe of Structural Changes upon the Occurrence of Halogen Bonding in Co-crystals [PDF]

open access: yes, 2013
Although the understanding of intermolecular interactions, such as hydrogen bonding, is relatively well-developed, many additional weak interactions work both in tandem and competitively to stabilize a given crystal structure.
