Butyrylcholinesterase genetic variants: association with cocaine dependence and related phenotypes.

open access: yesPLoS ONE, 2013
ObjectiveThe search for genetic vulnerability factors in cocaine dependence has focused on the role that neuroplasticity plays in addiction. However, like many other drugs, the ability of an individual to metabolize cocaine can also influence ...

Hypocretin / Orexin Receptor 1 Knockdown in GABA or Dopamine Neurons in the Ventral Tegmental Area Differentially Impact Mesolimbic Dopamine and Motivation for Cocaine

open access: yesAddiction Neuroscience, 2023
The hypocretins/orexins (HCRT) have been demonstrated to influence motivation for cocaine through actions on dopamine (DA) transmission. Pharmacological or genetic disruption of the hypocretin receptor 1 (Hcrtr1) reduces cocaine self-administration ...

Repeated \u3cem\u3eN\u3c/em\u3e-Acetylcysteine Administration Alters Plasticity-Dependent Effects of Cocaine [PDF]

open access: yes, 2007
Cocaine produces a persistent reduction in cystine–glutamate exchange via system xc− in the nucleus accumbens that may contribute to pathological glutamate signaling linked to addiction.

Dried blood spot analysis in antidoping: Technical challenges, analytical advances, and future perspectives

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Dried blood spot (DBS) analysis enables minimally invasive blood collection with strong analyte stability and simplified logistics, supporting anti‐doping applications beyond traditional matrices. Recent advances address hematocrit, volume variability, and matrix effects while expanding coverage to steroid esters, World Anti‐Doping Agency‐listed ...

A mechanism for the inhibition of neural progenitor cell proliferation by cocaine.

open access: yesPLoS Medicine, 2008
BackgroundPrenatal exposure of the developing brain to cocaine causes morphological and behavioral abnormalities. Recent studies indicate that cocaine-induced proliferation inhibition and/or apoptosis in neural progenitor cells may play a pivotal role in

Combined cocaine hydrolase gene transfer and anti-cocaine vaccine synergistically block cocaine-induced locomotion. [PDF]

open access: yesPLoS ONE, 2012
Mice and rats were tested for reduced sensitivity to cocaine-induced hyper-locomotion after pretreatment with anti-cocaine antibody or cocaine hydrolase (CocH) derived from human butyrylcholinesterase (BChE). In Balb/c mice, direct i.p. injection of CocH

Methylphenidate treatment beyond adolescence maintains increased cocaine self-administration in the spontaneously hypertensive rat model of attention deficit/hyperactivity disorder [PDF]

open access: yes, 2015
Past research with the spontaneously hypertensive rat (SHR) model of attention deficit/hyperactivity disorder showed that adolescent methylphenidate treatment enhanced cocaine abuse risk in SHR during adulthood.

Pathologic manifestations of levamisole-adulterated cocaine exposure. [PDF]

open access: yes, 2015
UnlabelledRheumatic manifestations of cocaine have been well described, but more recently, a dramatic increase in the levamisole-adulterated cocaine supply in the United States has disclosed unique pathologic consequences that are distinct from pure ...

Chemical Straightening as a Source of Analytical Variability in Hair Testing: A Dual‐Analyte Case Report

open access: yesDrug Testing and Analysis, EarlyView.
ABSTRACT Hair analysis is increasingly used in forensic toxicology; however, result interpretation may be influenced by cosmetic hair treatments. Although the effects of bleaching, dyeing, and thermal straightening have already been evaluated, data on permanent chemical hair straightening are scarce, particularly under in vivo conditions.
