Designing a norepinephrine optical tracer for imaging individual noradrenergic synapses and their activity in vivo

Nature Communications, 2018
Norepinephrine is a monoamine neurotransmitter with a wide repertoire of physiological roles in the peripheral and central nervous systems. There are, however, no experimental means to study functional properties of individual noradrenergic synapses in ...

Elevated Norepinephrine may be a Unifying Etiological Factor in the Abuse of a Broad Range of Substances: Alcohol, Nicotine, Marijuana, Heroin, Cocaine, and Caffeine

Substance Abuse: Research and Treatment, 2013
A wide range of commonly abused drugs have effects on the noradrenergic neurotransmitter system, including alterations during acute intoxication and chronic use of these drugs.

Antidepressant Misuse in Esports: A Review of Pharmacology, Adverse Effects, Pharmacokinetics and Biomatrix‐Based Detection for Anti‐Doping Applications

Drug Testing and Analysis, EarlyView.
This review highlights the misuse of antidepressants as potential cognitive‐enhancing agents in Esports. Despite pharmacological effects that overlap with those of psychostimulants, antidepressants remain an under‐recognised source of doping in Esports.

Ketogenic diet for infantile epileptic spasms

Epilepsia Open, EarlyView.
Abstract Approximately half of all cases of Infantile Epileptic Spasms Syndrome (IESS) do not respond to vigabatrin and hormonal therapies. There is no clear consensus as to the second‐line therapy for IESS. Ketogenic diet (KD) has emerged as an effective treatment for certain drug‐resistant epilepsies and in many cases of IESS.

Acute Modafinil Exposure Induces Neurobehavioral Alterations in Zebrafish: Implications for Off‐Label Cognitive Enhancement

Journal of Applied Toxicology, EarlyView.
ABSTRACT Modafinil (2‐(benzhydrylsulfinyl)acetamide) is a psychostimulant commonly prescribed for sleep disorders such as narcolepsy, excessive daytime sleepiness, and obstructive sleep apnea. Recently, its use has extended beyond clinical indications, with neurotypical individuals adopting it as a smart drug to enhance alertness and cognitive ...

Cardiac MIBG Scintigraphy in Neurodegenerative Parkinsonism: Limitations in Clinical Practice

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Reduced cardiac uptake on 123Iodine‐metaiodobenzylguanidine (MIBG) scintigraphy is a valuable tool for differentiating neurodegenerative parkinsonism but interpretation can be difficult due to comorbidities and drug‐tracer interactions.

Tracking Genetic Parkinson's Disease with Molecular Imaging: A Systematic Review

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Parkinson's disease (PD) is a worldwide, complex neurodegenerative disorder influenced by both genetic and environmental factors. Around 15–20% of PD cases are linked to genetic mutations, providing insights into the disease's pathogenesis.

The Noradrenergic Locus Coeruleus as a Chronic Pain Generator

Journal of Neuroscience Research, 2016
Central noradrenergic centers such as the locus coeruleus (LC) are traditionally viewed as pain inhibitory; however, complex interactions among brainstem pathways and their receptors modulate both inhibition and facilitation of pain.

Antidepressant-like Effects of Garcinia nigrolineata Resin Extract in a Chronic Mild Stress Mouse Model: Modulation of Monoaminergic and HPA-Axis Pathways

Plants
The resin extract of Garcinia nigrolineata (GNR-E), a tropical plant used in Southeast Asian traditional medicine, was evaluated for its antidepressant-like effects in a chronic mild stress (CMS) mouse model, with imipramine as a reference drug.

The central noradrenergic system: an overview

African Journal of Psychiatry, 2007
The central noradrenergic system belongs to a group of brainstem neuromodulatory systems previously referred to as the ascending reticular activating system. In this article a heuristic model is presented of the central noradrenergic system depicting the major projections to other cerebral areas, its interactions with other neuromodulatory systems ...
