Summary: The aim of this study is to examine the methodological orientations in game addiction studies in Turkey between 2019 and 2022 in a holistic way and to present suggestions for new literature studies. The study found that out of 257 studies, 69 complied with the predetermined criteria. These studies explored the relationship between academic achievement, familial and social relationship problems, gaming behavior and game addiction in children and adolescents. It was discovered that gaming addiction was higher in male students, especially between the ages of 14-15. The findings suggest that further empirical studies should be conducted to address game addiction with different approaches using new literature.

Summary: Long-term exposure to morphine induces structural and synaptic plasticity in reward-related regions of the brain, playing a critical role in addiction. However, the morphine-induced neuroadaptations in the dorsal striatum, which is crucial for drug-related habit learning, have not been well studied. This study finds that prolonged treatment with morphine leads to retraction of dendritic arbor and loss of dendritic spines in the dorsal striatal projection neurons. Additionally, the dopamine D-4 receptor (D4R) is found to modulate striatal morphine-induced plasticity, as the combined treatment of morphine with a D4R agonist restores dendritic arbor and spine density while altering the electrical properties of the neurons.

Summary: The study suggests that the mesolimbic D4 receptor does not play a crucial role in regulating behavioral sensitization induced by hyperdopaminergia, extending to the therapeutic effects of clozapine. Alternative molecular targets should be prioritized for future therapeutics targeting hyperdopaminergia-dependent neuropsychiatric disorders.

Summary: The study aimed to develop potent and selective alpha 6-containing nAChR antagonists to explore modulation of dopamine release and regulation of motor function. CVN417, a novel compound, was identified as an antagonist of alpha 6-containing nAChR and was found to reduce firing frequency of noradrenergic neurons. CVN417 modulated phasic dopaminergic neurotransmission in an impulse-dependent manner and attenuated the resting tremor phenotype in a rodent model. These results suggest that selective antagonism of alpha 6-containing nAChR could be a therapeutic approach for movement dysfunctions such as Parkinson's disease.

Summary: The study demonstrated that methamphetamine (MA) increases c-Fos expression and synaptic plasticity in the orbitofrontal cortex (OFC) and dorsal striatum (DS). MA activates projection neurons from the OFC to the DS and affects conditioned place preference (CPP) scores. The study also showed that DA release in the OFC is increased in the MA group, and D1R neurons in the OFC-DS pathway play a role in MA addiction.

Summary: The decreased expression of a novel microRNA, novel-m009C, is found to be implicated in the hyperlocomotion induced by METH. The study identifies dopamine receptors D1 and D2 as regulators of novel-m009C expression in the nucleus accumbens, and increasing the levels of novel-m009C attenuates the rewarding effects of METH. These findings provide insights into the molecular mechanism underlying METH addiction and suggest a potential treatment strategy targeting small non-coding RNAs.

Summary: This article reviews the evidence for sex differences in vulnerability to addiction, focusing on the neural mechanisms underlying these differences. The interactions between estradiol and the dopamine system in the brain result in differences in motivated behaviors and drug-seeking between males and females. Estradiol increases females' motivation for psychostimulants and enhances the value of drug-related cues, ultimately increasing their susceptibility to relapse.

Summary: Drug addiction is a chronic relapsing disorder that poses a global problem, influenced by genetics and environmental factors. Recent research has emphasized the role of epigenetics in the intergenerational and transgenerational inheritance of drug addiction. Studies have shown that parental exposure to drugs of abuse (opioids, cocaine, nicotine, alcohol, and cannabis) before conception alters offspring phenotype and impacts neurochemical and neurostructural changes in the brain. This paper reviews the effects of parental drug exposure before gestation in animal models.

Summary: St. John's wort is a herbaceous plant with therapeutic effects on psychiatric and mood disorders. Its active components, hyperforin and hypericin, play a major role in these effects. Changes in neurotransmitter levels in depression are complex and St. John's wort has inconsistent effects on neurotransmitter levels. Glutamate and acetylcholine may be important neurotransmitters to study in future works, and the dualistic modulation on cholinergic signaling induced by St. John's wort is an interesting topic for future studies.

Summary: The involvement of the opioidergic system in the anxiolytic and antinociceptive responses induced by cholestasis was investigated. The results suggest that cholestasis and addiction can impact anxiety and pain behaviors, with mu-opioid receptors playing a key role in the anxiolytic and analgesic effects induced by cholestasis. Additionally, coadministration of morphine and tramadol can enhance these effects in both cholestatic and addicted mice.

Summary: This study evaluated the effects of co-treatment of orexin agents and citalopram on depression-like behavior and BDNF expression in the prefrontal cortex (PFC) of sleep-deprived male mice. It was found that sleep deprivation increased depression-like behavior while decreasing BDNF expression. Citalopram showed an antidepressant effect, which was potentiated by an orexin antagonist and reversed by orexin-1. The study suggests that the orexin system interacts with citalopram to modulate depression-like behavior in sleep-deprived mice.

Summary: This review article discusses the intricate roles of sleep deprivation (SD) in modulating depression. The inconsistent effects of SD on depression have been studied for decades, with a focus on SD duration. However, the inconsistent role of SD seems to be more complicated, and other factors such as brain-derived neurotrophic factor (BDNF), vascular endothelial growth factor (VEGF), serotonin, cortisol, and tumor necrosis factor-alpha (TNF-alpha) are involved. It was concluded that SD has inconsistent effects on BDNF, VEGF, serotonin, and cortisol levels. The diurnal rhythm of BDNF is significant in the modulatory role of SD in depression. VEGF is important in blood-brain barrier permeability which affects depression. Furthermore, there is a negative correlation between cortisol and BDNF, modulating depression. TNF-alpha regulates sleep/wake cycle and increases blood-brain barrier permeability, resulting in depressive behavior. Future studies should focus on these mechanisms/factors to better understand the complex roles of SD in modulating depression.

Summary: Sleep deprivation has negative effects on cognitive functions, but some studies suggest it may improve cognitive functions. This study investigated the effects of 4-hour and 24-hour sleep deprivation, as well as mild short-term and moderate long-term treadmill exercise, on spatial memory performance and oxidative and antioxidant markers in rats. The results showed that 24-hour sleep deprivation and long-term moderate treadmill exercise had negative effects on memory and oxidative status. However, both treadmill exercise protocols reversed the negative effects of sleep deprivation on memory and oxidative stress.
