Shared Metabolic–Proteinopathy Axis in Alzheimer's Disease and Parkinson's Disease: Evidence for a Convergent but Not Identical Disease Spectrum

open access: yesAGING MEDICINE, EarlyView.
This review explores the common pathological mechanisms underlying Alzheimer's disease (AD) and Parkinson's disease (PD), with an emphasis on glucose metabolism and insulin resistance. We examine how disruptions in glucose metabolism and insulin resistance influence the onset and advancement of both Alzheimer's disease (AD) and Parkinson's disease (PD).

Nicotinic Receptor Activity Alters Synaptic Plasticity

open access: yesThe Scientific World Journal, 2001
Studies using specific agonists, antagonists, and lesions have shown that nicotinic cholinergic systems participate in attention, learning, and memory[1,2].

One‐Year Healthcare Utilization and Costs After Emergency Department Encounters for Uncomplicated Appendicitis: A Statewide Observational Study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Objective Non‐operative management with antibiotics has emerged as an alternative to appendectomy for uncomplicated appendicitis. This study compared one‐year healthcare costs and utilization outcomes after operative versus non‐operative management of uncomplicated appendicitis using statewide administrative data.

Molecular characterisation of insect nicotinic acetylcholine receptors [PDF]

open access: yes, 2003
Nicotinic acetylcholine receptors (nAChRs) are pentameric multi-subunit proteins that form ligand-gated ion channels in the central nervous systems of vertebrates and invertebrates and at the neuromuscular junction of vertebrate species. In insects, they

Striatal dopamine transmission is subtly modified in human A53Tα-synuclein overexpressing mice [PDF]

open access: yes, 2012
Mutations in, or elevated dosage of, SNCA, the gene for α-synuclein (α-syn), cause familial Parkinson's disease (PD). Mouse lines overexpressing the mutant human A53Tα-syn may represent a model of early PD.

Place‐based risk: Examining relationships between adolescent perceptions of community risk factors and adolescent substance use across geographic contexts

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Mixed evidence for the influence of structural and social factors on adolescent substance use behaviors exists across the rural–urban continuum. Therefore, this study explores how adolescent perceptions of structural and social community risk factors are associated with lifetime and past 30‐day use of alcohol, marijuana, cigarettes, and ...

CHRNA5 links chandelier cells to severity of amyloid pathology in aging and Alzheimer’s disease

open access: yesTranslational Psychiatry
Changes in high-affinity nicotinic acetylcholine receptors are intricately connected to neuropathology in Alzheimer’s Disease (AD). Protective and cognitive-enhancing roles for the nicotinic α5 subunit have been identified, but this gene has not been ...

Characterization of nAChRs in Nematostella vectensis supports neuronal and non-neuronal roles in the cnidarian–bilaterian common ancestor

open access: yesEvoDevo, 2019
Background Nicotinic and muscarinic acetylcholine receptors likely evolved in the cnidarian–bilaterian common ancestor. Both receptor families are best known for their role at chemical synapses in bilaterian animals, but they also have described roles as

Adipose‐derived mesenchymal stem cell injection into the KI10 acupoint mitigates cartilage damage in KOA rats through PGE2‐mediated α7nAChR/NF‐κB pathway

open access: yesAnimal Models and Experimental Medicine, EarlyView.
In our research, KOA rat models were established and treated with ADSC injection into the KI10 acupoint. Pain relief, behavioral function, and joint structural improvements were systematically assessed using ethological tests, imaging, histopathological staining, transmission electron microscopy, and molecular analyses.

Inhibition of nicotinic acetylcholine receptors, a novel facet in the pleiotropic activities of snake venom phospholipases A2.

open access: yesPLoS ONE, 2014
Phospholipases A2 represent the most abundant family of snake venom proteins. They manifest an array of biological activities, which is constantly expanding. We have recently shown that a protein bitanarin, isolated from the venom of the puff adder Bitis
