Methamphetamine (METH) is a popular new-type psychostimulant drug with complicated neurotoxicity. In spite of mounting evidence on METH-induced damage of neural cell, the accurate mechanism of toxic effect of the drug on central nervous system (CNS) has not yet been completely deciphered. Besides, effective treatment strategies toward METH neurotoxicity remain scarce and more efficacious drugs are to be developed. In this review, we summarize cellular and molecular bases that might contribute to METH-elicited neurotoxicity, which mainly include oxidative stress, excitotoxicity, and neuroinflammation...

Methamphetamine (METH) abuse is one the most worldwide problems with wide-ranging effects on the central nervous system (CNS). Chronic METH abuse can associate with cognitive abnormalities and neurodegenerative changes in the brain. Agmatine, a cationic polyamine, has been proposed as a neuromodulator that modulates many effects of abused drugs. The aim of this study was to determine if agmatine can decrease the impairment effect of METH on memory and hippocampal CaMKII-α gene expression, a gene that plays a major role in memory...

Although the benzodiazepine class of drugs has proven useful in treating anxiety symptoms, recent studies yield no consistent empirical support for their use in treating psychiatric disorders. However, animal studies using a fear conditioning paradigm have suggested that benzodiazepines facilitate fear memory extinction, dependent on treatment timing and subject conditions. However, we have no data on the effect of subject conditions. The purpose of this study was to investigate whether the effect of benzodiazepines depends on hypersensitivity to fear-memory processing...

It is now well-established that Australia has a significant issue with methamphetamine. Recent dramatic changes in manufacturing have led to significant shifts in both the patterns of use and the relative purity of this illicit drug, with the crystalline form of methamphetamine commonly referred to as 'ice'. Excessive use not only impacts on those taking the drug, but also takes a heavy toll on their families. With few effective treatment options currently available, there is a strong focus on developing replacement pharmacotherapies and examining the efficacy of outpatient counselling and residential treatment options...

Drugs incorporated into hair are exposed to the environment, and cosmetic and chemical treatments, with possible decreases in their content. Knowledge concerning the effect of sunlight on drug content in hair can be helpful to forensic toxicologists, in particular, when investigating drug concentrations above or below pre-determined cut-offs. Twenty authentic positive hair samples were selected which had previously tested positive for amphetamines and/or ketamine. Washed hair were divided into two identical strands, with the former exposed at 765 W/m² (300⁻800 nm spectrum of irradiance) for 48 h in a solar simulator, and the latter kept in the dark...

Methamphetamine (METH) is a commonly abused psychostimulant that can induce severe neurotoxicity. Cardiovascular injury caused by METH has recently gained increasing attention; however, the underlying mechanisms remain unclear. As autophagy has been shown to be associated with cell injury, the association between autophagy and METH-mediated cell apoptosis was investigated in the present study. METH treatment significantly increased the expression of two key autophagy proteins, i.e., Beclin-1 and LC3-II, in the cardiomyocyte cell line H9C2...

Women have greater vulnerability to alcohol problems than men. They become intoxicated after drinking half as much as men, develop cirrhosis of the liver more rapidly, and have a greater risk of dying from alcohol-related accidents. Despite more serious consequences related to their drinking, treatment for women with alcohol use disorders has been understudied relative to treatment for men. Intensive motivational interviewing (IMI) is a recent psychotherapeutic intervention for substance abuse problems that draws on the principles of brief motivational interviewing (1-2 session)...

Adolescents and females experience worse outcomes of drug use compared to adults and males. This could result from age- and sex-specific consequences of drug exposure on brain function and cognitive behavior. In the current study, we examined whether a history of intravenous methamphetamine (METH) self-administration impacted cognitive flexibility and 5-HT2C R localization in the orbitofrontal cortex (OFC) in an age- and sex-dependent manner. Strategy shifting was assessed in male and female Sprague-Dawley rats that had self-administered METH (0...
