Proteolytic stabilization of a spider venom peptide results in an orally active bioinsecticide

Pest Management Science, EarlyView.
Selective editing out of an insect gut protease cleavage site renders a spider‐derived insecticidal peptide active by ingestion by insect pests. Abstract BACKGROUND The toxin peptide U1‐AGTX‐Ta1b from the Hobo spider, Eratigena agrestis (Walckenaer, 1802), was studied to determine its potential to serve as a bioinsecticide.

Investigation of the Possible Pharmacologically Active Forms of the Nicotinic Acetylcholine Receptor Agonist Anabaseine

Marine Drugs, 2019
Three major forms of the nicotinic agonist toxin anabaseine (cyclic iminium, cyclic imine and the monocationic open-chain ammonium-ketone) co-exist in almost equal concentrations at physiological pH.

Effects of novel muscarinic M3 receptor ligand C1213 in pulmonary arterial hypertension models. [PDF]

, 2016
Pulmonary hypertension (PH) is a complex disease comprising a pathologic remodeling and thickening of the pulmonary vessels causing an after load on the right heart ventricle that can result in ventricular failure. Triggered by oxidative stress, episodes

Malignancies and immunoglobulin G4‐related disease

Rheumatology &Autoimmunity, EarlyView.
Immunoglobulin G4‐related disease (IgG4‐RD) is associated with increased cancer risk. Malignancies affect both IgG4‐RD involved organs, such as the lung, pancreas, bile duct, and prostate, and noninvolved organs, such as the gastrointestinal duct. B‐cell neoplasms constitute a proportion of the malignancies linked to this disease.

Beta amyloid differently modulate nicotinic and muscarinic receptor subtypes which regulate in vitro and in vivo the release of glycine in the rat hippocampus

Frontiers in Pharmacology, 2012
Using both in vitro (hippocampal synaptosomes in superfusion) and in vivo (microdialysis) approaches we investigated whether and to what extent β amyloid peptide 1-40 (Aβ 1-40) interferes with the cholinergic modulation of the release of glycine (GLY) in

Psychedelic‐assisted treatment for substance use disorder: A narrative systematic review

Addiction, EarlyView.
Abstract Background and aims This is the first systematic review of the extant literature on all major psychedelic‐assisted treatment for alcohol use disorder (AUD), tobacco use disorder (TUD) and other substance use disorders (SUD). We aimed to summarise the evidence for efficacy of psychedelic‐assisted treatment for AUD, TUD, and SUD; to evaluate its

Synthetic cannabinoids in e‐cigarettes seized from English schools

Addiction, EarlyView.
Abstract Background and aims People who use synthetic cannabinoids (SCs) report debilitating side effects and withdrawal symptoms, coupled with dependence. In the UK, SC use was believed to be largely restricted to prison, where they are the most common drug and associated with nearly half of non‐natural deaths, or poly‐drug users in the community who ...

A tight coupling between β\u3csub\u3e2\u3c/sub\u3eY97 and β\u3csub\u3e2\u3c/sub\u3eF200 of the GABA\u3csub\u3eA\u3c/sub\u3e receptor mediates GABA binding [PDF]

, 2011
The GABAA receptor is an oligopentameric chloride channel that is activated via conformation changes induced upon the binding of the endogenous ligand, GABA, to the extracellular inter-subunit interfaces. Although dozens of amino acid residues at the α/β

Elevated Hippocampal Cholinergic Neurostimulating Peptide precursor protein (HCNP-pp) mRNA in the amygdala in major depression [PDF]

, 2015
The amygdala is innervated by the cholinergic system and is involved in major depressive disorder (MDD). Evidence suggests a hyper-activate cholinergic system in MDD.

Among people who use heroin, tobacco smoking and illegal drugs cause a similar number of premature deaths

Addiction, EarlyView.
Abstract Background and aims Most people who use heroin also smoke tobacco, but there is limited investment to reduce the prevalence of smoking in this group. This may be due to a perception that tobacco is less harmful than other substances and is a lower priority problem. Among people who use heroin in England, we aimed to compare tobacco smoking and
