BACKGROUND AND OBJECTIVE: Previously it was demonstrated that digitalis-like cardiotonic steroid, marinobufagenin (MBG), is implicated in the development of ethanol addiction in rats. We hypothesized that (i) levels of sodium pump ligand, MBG, would be negatively correlated with amount of ethanol consumed by rats, and (ii) that spironolactone would oppose the MBG induced ethanol-seeking behavior and blood pressure in rats. METHODS: Voluntary consumption of 9% alcohol (vs...

BACKGROUND: The incidence of post-surgical chronic pain ranges between 20% and 40% in Europe. Osteoarthritis pain after prosthesis implantation is one of the most severe secondary syndromes, depending not only on surgery but also on organic changes before and after joints replacement. No data are available about risk factors. An excessive inflammatory response plays a central role but a best therapy is not defined yet. It is not clear whether opioid administration could influence post-surgical pain and lead to tolerance or addiction...

Gender differences in psychiatric disorders such as addiction may be modulated by the steroid hormone estrogen. For instance, 17β-estradiol (E2), the predominant form of circulating estrogen in pre-menopausal females, increases ethanol consumption, suggesting that E2 may affect the rewarding properties of ethanol and thus the development of alcohol use disorder in females. The ventral tegmental area (VTA) is critically involved in the rewarding and reinforcing effects of ethanol. In order to determine the role of E2 in VTA physiology, gonadally intact female mice were sacrificed during diestrus II (high E2) or estrus (low E2) for electrophysiology recordings...

Neuropathic pain is a complex and debilitating syndrome for which there are few effective pharmacological treatments. Opioid-based medications are initially effective for acute pain but tolerance to their analgesic effects quickly develops and long-term use often leads to physical dependence and addiction. Furthermore, neuropathic pain is generally resistant to non-steroidal anti-inflammatory drugs. Other classes of medications including antidepressants, antiepileptics, and voltage-gated calcium channel (VGCC) inhibitors are only partially effective in most patients, may be associated with significant side effects, and have few disease modifying effects on the underlying pathology...

Neonatal neuroactive steroids levels are crucial for brain development. Alterations of neonatal neuroactive steroids levels induce anxiolytic-like effects and improve exploration in novel environments in adulthood. These behavioural traits, i.e. sensation/novelty seeking, anxiety or impulsivity, are associated with vulnerability to drug use and abuse. Adolescence is also recognized as a particularly critical developmental phase to contribute to vulnerable phenotype. However, the influence of neuroactive steroids during development in the vulnerability to drug addiction has been poorly studied...

Benzydamine (BZY) is a non-steroidal anti-inflammatory drug used for the topical treatment of inflammations of the oral and vaginal mucosae. Virtually nothing is known about the central pharmacological actions of BZY. Yet there are reports of voluntary systemic overdosage of BZY in drug addicts, resulting in a euphoric, hallucinatory state. In the present study, we investigated the reinforcing properties of BZY in a rat self-administration paradigm. We found that BZY has a powerful reinforcing effect and that this effect is greatly facilitated in animals that already had substance experience, having previously self-administered heroin and cocaine, indicating cross sensitization between BZY and other common drugs of abuse...

Commonly used for analgesic and anti-inflammatory effects, non-steroidal anti-inflammatory drugs (NSAIDs) are among the most frequently used medications in the world. In spite of their prevalence, reports of NSAID misuse and NSAID use disorder are uncommon. This case report describes a research participant who met criteria for DSM-5 moderate substance use disorder based on her use of prescribed ibuprofen as assessed by the validated Mini International Neuropsychiatric Interview (MINI). This case demonstrates that the DSM-5 criteria within the MINI can be applied to diagnose an NSAID use disorder...

Food intake is reduced by estrogenic hormones, levels of which vary throughout life and fluctuate throughout the ovarian cycle in females. However, estrogens have also been shown to increase reward derived from drugs of abuse, where motivational properties of drugs and progression to addiction are potentiated by estrogens. Whether reward derived from food, and specifically motivational properties of food, are altered by estrogens remains unknown. Here we investigated the effect of the estrous cycle on food reward behavior and show estrous cycle dictated variability in food motivation, measured by progressive ratio operant conditioning, in female rats...

INTRODUCTION    Graves ophthalmopathy (GO) is an autoimmune disease associated with Graves disease. Its treatment is largely dependent on the severity and activity of ocular lesions. Particular attention should be given to radioiodine (RAI) therapy. Although its use is a valuable therapeutic option for hyperthyroidism, it may be followed by worsening of GO.  OBJECTIVES    The aim of the present study was to analyze how the severity of nicotine addiction affects the response to RAI treatment in patients with GO...

Rare metabolic diseases may sometimes arise acutely and endanger human life if not immediately recognized and treated. Marchiafava Bignami disease is an uncommon neurologic disorder described in alcohol abusers and characterized by an acute severe damage of brain white matter. Even more rarely, it has been reported in non-alcohol addicted patients, but never in vegetarian people. This is a case report of a young vegetarian woman, accustomed to drink high amounts of tea, who, three weeks after her first natural childbirth, developed serious motor and cognitive disturbances...

A series of steroids present in the brain have been named "neurosteroids" following the possibility of their role in the central nervous system impairments such as anxiety disorders, depression, premenstrual dysphoric disorder (PMDD), addiction, or even neurodegenerative disorders such as Alzheimer's and Parkinson's diseases. Study of their potential role requires a sensitive and accurate assay of their concentration in the monkey brain, the closest model to the human. We have thus developed a robust, precise and accurate liquid chromatography-tandem mass spectrometry method for the assay of pregnenolone, pregnanolone, epipregnanolone, allopregnanolone, epiallopregnanolone, and androsterone in the cynomolgus monkey brain...

Anabolic androgenic steroids (AAS) are substances that mimic the hormone testosterone, and primarily act via the androgen receptor. In addition to their physiological effect on muscle tissue and growth, research from the last decade has shown that AAS have a pronounced impact on the central nervous system. A large number of studies have demonstrated that AAS affect the mesolimbic reward system in the brain. However, whether the direct effects of AAS on endorphins, dopamine, serotonin and GABA etc. and on the corresponding and related systems lead to dependence needs to be further elucidated...

Dear Editor, Ultraviolet (UV) radiation is a well-known physical hazard responsible for photoaging, photoallergic, and phototoxic reactions as well as carcinogenesis, including life-threatening melanomas (1,2). Overexposure to both natural and artificial UV radiation is a public health concern. 30% of cancers diagnosed worldwide are skin cancers. Approximately three million non-melanoma skin cancers and 132 000 new cases of melanomas are diagnosed globally each year (3). Sunburns, especially in childhood, are a very important risk factor for melanomas...

BACKGROUND: Analgesics are the drugs which bring insensibility to pain without loosing consciousness. Treatment strategy is generally based on the type of pain. Most of the analgesics are associated with serious side effects, such as NSAIDS can cause severe GI disturbance and opioids can cause addiction. There are various ways to reduce their side effects The analgesic prodrug approach is one of the several strategies used to attain the required pharmacological response with a considerable decrease in side effects...

Sigma1 receptors (σ1Rs) are expressed widely; they bind diverse ligands, including psychotropic drugs and steroids, regulate many ion channels, and are implicated in cancer and addiction. It is not known how σ1Rs exert such varied effects. We demonstrate that σ1Rs inhibit store-operated Ca(2+)entry (SOCE), a major Ca(2+)influx pathway, and reduce the Ca(2+)content of the intracellular stores. SOCE was inhibited by expression of σ1R or an agonist of σ1R and enhanced by loss of σ1R or an antagonist. Within the endoplasmic reticulum (ER), σ1R associated with STIM1, the ER Ca(2+)sensor that regulates SOCE...

Among mammals, every cell has a biological sex, and the sex of an individual pervades its body and brain. In this review, we describe the processes through which mammals become phenotypically male or female by organizational and activational influences of genes and hormones throughout development. We emphasized that the molecular and cellular changes triggered by sex chromosomes and steroid hormones may generate sex differences in overt physiological functions and behavior, but they may alternatively promote end-point convergences between males and females...
