Nicotine Inhibits Clostridium difficile Toxin A-Induced Colitis but Not Ileitis in Rats
International Journal of Inflammation, 2016 Nicotine is protective in ulcerative colitis but not Crohn’s disease of the small intestine, but little is known about the effects of nicotine on Clostridium difficile toxin A-induced enteritis.

BMC Neuroscience, 2018 Background The treatment of Parkinson’s disease is often complicated by levodopa-induced dyskinesia (LID). Nicotinic acetylcholine receptor agonists can alleviate LID in animal models but may be less effective in conditions of severe dopaminergic ...

Influence of nicotine and alcohol on sleep latency: the reward-attention circuit model [PDF]
arXiv, 2019 We previously developed a neurocomputational model called the reward-attention circuit, which has been used to investigate the separate effects of nicotine and alcohol on attention focus. The model is based on known circuits linking midbrain dopaminergic neurons to the thalamocortical loop and is sufficiently versatile to capture diverse phenomena.

Design Paradigms Based on Spring Agonists for Underactuated Robot Hands: Concepts and Application [PDF]
arXiv, 2020 In this paper, we focus on a rarely used paradigm in the design of underactuated robot hands: the use of springs as agonists and tendons as antagonists. We formalize this approach in a design matrix also considering its interplay with the underactuation method used (one tendon for multiple joints vs. multiple tendons on one motor shaft).

Molecular dynamics simulations reveal the role of ceramicine B as novel PPARγ partial agonist against type 2 diabetes [PDF]
arXiv, 2018 Peroxisome proliferator-activated receptors gamma (PPAR{\gamma}) are ligand-activated controllers of various metabolic actions and insulin sensitivity. PPAR{\gamma} is thus considered as an important target to treat type 2 diabetes. Available PPAR{\gamma} drugs (full agonists) have robust insulin-sensitizing properties but are accompanied by severe ...

A weighted U statistic for association analysis considering genetic heterogeneity [PDF]
, 2015 Converging evidence suggests that common complex diseases with the same or similar clinical manifestations could have different underlying genetic etiologies. While current research interests have shifted toward uncovering rare variants and structural variations predisposing to human diseases, the impact of heterogeneity in genetic studies of complex ...

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.

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.

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
