Transitioning to nonpunitive school policies for addressing student substance use: Qualitative interviews with key school administrators

American Journal of Community Psychology, EarlyView.
Abstract Recent policy change in Massachusetts encourages schools to limit their use of exclusionary discipline to “extraordinary circumstances,” but little work has explored the opportunities and challenges of transitioning to nonpunitive practices after student substance use infractions in schools.

Nicotinic Receptor Activity Alters Synaptic Plasticity

The 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].

Lynx1 Modulation of Nicotinic Acetylcholine Receptors [PDF]

, 2015
Nicotinic receptors are the target of nicotine in the brain. They are pentameric ion channels. The pentamer structure allows many combinations of receptors to be formed.

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

Animal 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.

Molecular and Physicochemical Aspects of Local Anesthetics Acting on Nicotinic Acetylcholine Receptor-containing Membranes [PDF]

, 2002
Local anesthetics inhibit the ion channel activity of nicotinic acetylcholine receptors in a noncompetitive fashion. This inhibitory action is ascribed to two possible inhibitory mechanisms: an open-channel-blocking mechanism and/or an allosteric process

Neurotransmitter‐Defined Degeneration Patterns in Sporadic and C9orf72‐Associated Amyotrophic Lateral Sclerosis: Predilection to GABAergic, Serotonergic, Opioid, Glutamatergic, Endocannabinoid, and Microglial Systems—Implications for Therapy Development

Annals of Neurology, EarlyView.
Objective Amyotrophic lateral sclerosis (ALS) has a markedly distinctive clinical and neuroradiological signature, with the preferential involvement of specific brain networks and the apparent sparing of others. The molecular underpinnings of the strikingly selective anatomical vulnerability have not been fully elucidated to date despite the potential ...

Molecular characterisation of insect nicotinic acetylcholine receptors [PDF]

, 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

Loop B is a major structural component of the 5-HT3 receptor [PDF]

, 2008
The 5-HT3 receptor belongs to a family of therapeutically important neurotransmitter-gated receptors whose ligand binding sites are formed by the convergence of six peptide loops (A-F).

Reframing the Gut–Brain Axis: The Gut Wall as a Neural Immune Interface in Multiple Sclerosis and Autoimmune Neurological Diseases

Annals of Neurology, EarlyView.
Gut wall physiology in multiple sclerosis (MS) and autoimmune neurologic diseases remains underexplored but may span gut barrier dysfunction, enteric glial targeting, mucosal immune dysregulation, and autoimmune targets within the enteric nervous system (ENS).
