Vitamin D deficiency induces erectile dysfunction: Role of superoxide and Slpi
British Journal of Pharmacology, EarlyView.Background and Purpose Epidemiological studies suggest a relationship between vitamin D deficiency and erectile dysfunction (ED). We hypothesized that vitamin D deficiency or vitamin D receptor (VDR) knockout causes ED and analysed the underlying molecular mechanisms.

British Journal of Pharmacology, EarlyView.Abstract Background and Purpose Several G protein‐coupled receptors (GPCRs) are known to homodimerise. Dimeric GPCRs may have different properties from their monomers, but the molecular basis and functional significance of GPCR dimerisation remain largely unknown.

Systems level circuit model of C. elegans undulatory locomotion: mathematical modeling and molecular genetics [PDF]
Journal of Computational Neuroscience 24, 253-276 (2008), 2007 To establish the relationship between locomotory behavior and dynamics of neural circuits in the nematode C. elegans we combined molecular and theoretical approaches. In particular, we quantitatively analyzed the motion of C. elegans with defective synaptic GABA and acetylcholine transmission, defective muscle calcium signaling, and defective muscles ...

Acetylcholine release and inhibitory interneuron activity in hippocampal CA1
Frontiers in Synaptic Neuroscience, 2014 Acetylcholine release in the central nervous system (CNS) has an important role in attention, recall and memory formation. One region influenced by acetylcholine is the hippocampus, which receives inputs from the medial septum and diagonal band of Broca ...

The surface accessibility of α-bungarotoxin monitored by a novel paramagnetic probe [PDF]
arXiv, 2011 The surface accessibility of {\alpha}-bungarotoxin has been investigated by using Gd2L7, a newly designed paramagnetic NMR probe. Signal attenuations induced by Gd2L7 on {\alpha}-bungarotoxin C{\alpha}H peaks of 1H-13C HSQC spectra have been analyzed and compared with the ones previously obtained in the presence of GdDTPA-BMA. In spite of the different

Internal Medicine Journal, EarlyView.Abstract Hyperhidrosis is an under‐reported and under‐treated condition that causes significant patient morbidity. Secondary causes require consideration, but the vast majority of cases are idiopathic. The condition is encountered by a range of clinicians, including neurologists, dermatologists and endocrinologists, and it pays to be familiar with the ...

Toxins, 2011 Muscarinic toxin 7 (MT7) is a mamba venom peptide that binds selectively to the M1 muscarinic acetylcholine receptor. We have previously shown that the second (ECL2) and third (ECL3) extracellular loops of the M1 receptor are critically involved in ...

The human colon: Evidence for degenerative changes during aging and the physiological consequences
Neurogastroenterology &Motility, EarlyView.Reduced nociceptor innervation can explain diminished abdominal pain among the elderly. Degenerative changes occur within the colon wall, especially ascending colon. Mechanisms may include senescence‐like activity and inflammaging. Constipation is more likely to occur during age‐related challenges affecting functions of the bowel that now have reduced ...

Mechanisms of enteric neuropathy in diverse contexts of gastrointestinal dysfunction
Neurogastroenterology &Motility, EarlyView.Abstract The enteric nervous system (ENS) commands moment‐to‐moment gut functions through integrative neurocircuitry housed in the gut wall. The functional continuity of ENS networks is disrupted in enteric neuropathies and contributes to major disturbances in normal gut activities including abnormal gut motility, secretions, pain, immune dysregulation,

Monod-Wyman-Changeux Analysis of Ligand-Gated Ion Channel Mutants [PDF]
arXiv, 2017 We present a framework for computing the gating properties of ligand-gated ion channel mutants using the Monod-Wyman-Changeux (MWC) model of allostery. We derive simple analytic formulas for key functional properties such as the leakiness, dynamic range, half-maximal effective concentration, and effective Hill coefficient, and explore the full spectrum
