Opening a hydrophobic gate: the nicotinic acetylcholine receptor as an example [PDF]
arXiv, 2009 To what extent must a hydrophobic gate expand for the channel to count as open? We address this question using the nicotinic acetylcholine receptor (nAChR) as the exemplar. The nAChR is an integral membrane protein which forms a cation selective channel gated by neurotransmitter binding to its extracellular domain.

Clinical Pharmacology in Drug Development, EarlyView.Abstract Dordaviprone (ONC201) is a novel, small molecule imipridone with antitumor effects in glioma patients. This study evaluated the pharmacokinetics and safety of dordaviprone following single escalating doses (Part A), as a capsule content mixed with applesauce or Gatorade (sports drink) [Part B1]), and with or without food [Part B2].

PROTEOMICS, Volume 22, Issue 23-24, December 2022., 2022 Abstract The X‐linked inherited neuromuscular disorder Duchenne muscular dystrophy is characterised by primary abnormalities in the membrane cytoskeletal component dystrophin. The almost complete absence of the Dp427‐M isoform of dystrophin in skeletal muscles renders contractile fibres more susceptible to progressive degeneration and a leaky ...

Rapid Analytical Method for Quantification of Gamma‐Hydroxybutyrate (GHB) in Hair by UPLC‐MS/MS
Drug Testing and Analysis, EarlyView.A rapid and simple UPLC‐MS/MS method for quantification of GHB in 10 mg of hair was developed. The method was satisfactorily validated, showing a linear range of 0.5–50 ng/mg, which allows us to quantify endogenous and exogenous GHB concentrations.

Boundary lipids of the nicotinic acetylcholine receptor: spontaneous partitioning via coarse-grained molecular dynamics simulation [PDF]
arXiv, 2018 Reconstituted nicotinic acetylcholine receptors (nAChRs) exhibit significant gain-of-function upon addition of cholesterol to reconstitution mixtures, and cholesterol affects organization of nAChRs within domain-forming membranes, but whether nAChR partitions to cholesterol-rich liquid-ordered ("raft" or $l_o$) domains or cholesterol-poor liquid ...

Drug Testing and Analysis, EarlyView.Waxy‐ or putty‐like materials has emerged as a novel drug preparation for synthetic cannabinoids and other drugs in UK prisons. An in vitro CB1 bioassay was used to evaluate the CB1 activating potential of MDMB‐INACA and extracts from eight seized samples. MDMB‐INACA had moderate efficacy but low potency at CB1.

Predicting Smoking Events with a Time-Varying Semi-Parametric Hawkes Process Model [PDF]
arXiv, 2018 Health risks from cigarette smoking -- the leading cause of preventable death in the United States -- can be substantially reduced by quitting. Although most smokers are motivated to quit, the majority of quit attempts fail. A number of studies have explored the role of self-reported symptoms, physiologic measurements, and environmental context on ...
