MicroRNA Regulation of nAChR Expression and Nicotine-Dependent Behavior in C. elegans

Cell Reports, 2017
Summary: Chronic exposure to nicotine upregulates nicotinic acetylcholine receptors (nAChRs), and such upregulation is critical for the development of nicotine dependence in humans and animal models.

Chronic Nicotine Selectively Enhances α4β2* Nicotinic Acetylcholine Receptors in the Nigrostriatal Dopamine Pathway [PDF]

, 2009
These electrophysiological experiments, in slices and intact animals, study the effects of in vivo chronic exposure to nicotine on functional α4β2* nAChRs in the nigrostriatal dopaminergic (DA) pathway.

Overview of Encapsulated Lysine and Methionine and Their Impacts on Transition Cow Performance and Health

Animal Research and One Health, EarlyView.
The transition period in dairy cows, spanning 3 weeks before and after calving, is a critical phase characterized by increased nutrient demands, reduced dry matter intake (DMI), and elevated risk of metabolic disorders such as negative nutrient balance (NNB), lipolysis, proteolysis, and oxidative stress.

Comprehensive Characterization of Acer truncatum Leaf Extract: Identification of Systemic Metabolites and Effects on Performance, Antioxidant Status, and Intestinal Microbiota in Laying Hens

Animal Research and One Health, EarlyView.
Dietary A. truncatum leaf extract is absorbed and improves laying performance in aged hens by enhancing systemic antioxidant capacity and modulating the gut microbiota. ABSTRACT The demand for natural feed additives is considerably increasing in the antibiotic‐free feed era.

Visual Hypersensitivity as a Transdiagnostic Marker of Surgical Pain Response in Arthritis and Chronic Pain Syndromes

Arthritis &Rheumatology, EarlyView.
Objective Nociplastic pain is pain primarily driven by the central nervous system and, unlike nociceptive pain conditions, is thought to be refractory to peripherally directed therapies. Nociplastic pain is also associated with hypersensitivity to painful and other sensory stimuli (such as visual stimuli). Nonpainful sensory measures have not been well

Low‐dose cannabidiol increases plasma concentrations of amitriptyline: A clinical drug–drug interaction study

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aims Cannabidiol (CBD), the main non‐intoxicating compound from the cannabis plant, is regularly used by patients with chronic pain who also take analgesics. CBD has previously been shown to inhibit CYP‐mediated drug metabolism. This study aimed to characterize the potential pharmacokinetic interaction of CBD with amitriptyline and tramadol ...

Nicotine flux and pharmacokinetics-based considerations for early assessment of nicotine delivery systems

Drug and Alcohol Dependence Reports
In the past few years, technological advancements enabled the development of novel electronic nicotine delivery systems (ENDS). Several empirical measures such as “nicotine flux” are being proposed to evaluate the abuse liability potential of these ...

An update on nicotine replacement therapy

Journal of Oral Research and Review, 2019
Tobacco use is the single greatest preventable cause of death in the world. Most tobacco users want to quit but find it difficult to stop due to the addictiveness of nicotine. Interventions for tobacco cessation are important in enabling tobacco users to

Pharmacokinetics and pharmacodynamics of intravenous and oral (S)‐ketamine: Investigating metabolite contribution to subjective effects

British Journal of Clinical Pharmacology, EarlyView.
Aims Oral administration of (S)‐ketamine for treatment‐resistant depression (TRD), as alternative to the registered intranasal or off‐label intravenous administrations, has high potential. However, it is characterized by an extensive first‐pass metabolism, resulting in low (S)‐ketamine exposure and high levels of active metabolites, including (S ...
