The aim of this paper is to present the current state of knowledge about microRNAs in alcohol use disorder (AUD). Particular emphasis was placed on estimating the possibility of using microRNA molecules as biomarkers of diagnostic, prognostic and predictive significance as well as potential therapeutic targets in alcohol-related disorders. For this purpose the PubMed, Science Direct and Wiley Online Library medical databases were reviewed using the following phrases: “ncRNA”, “microRNA”, “circulating microRNA”, “miRNA”, “alcohol use disorder”, “alcohol addiction”, “alcohol abuse”, “alcoholism”, “bioStreszczenie

The consumption of ethanol disturbs oxida-tive-reductive balance in the liver leading to oxidative stress, which plays an glutathione, as well as increased activity of glutathione reductase, while in the case of catalase and glutathione peroxidise, depending on the study, there is either an increase or decrease of these enzymes activity in the liver. This may be due to the age and gender of animals, different experimental conditions, exposure time, ethanol solution dosage and concentration as well as the methods of administration of the ethanol solution. It should be noted that the experiments were conducted mainly on male rats or mice, which, compared to females, are less susceptible to alcohol-induced damage, and more to oxidative stress, which may have also affected the observed results.

Introduction: The paper describes the process of developing a tool to measure social networking site addiction among adolescents, that is the Scale of Excessive Use of Social Networking Sites (SEUS). Material and methods: Three studies (Study 1, N = Study 2, N = 351; Study 3, N = 1054) were performed to establish psychometric properties, construct and criterion validity of SEUS Słowa among Polish high school students. Two different versions of SEUS were developed (48- and 30-item). Their results were correlated with the Bergen Facebook Addiction Scale (BFAS) and standardised questionnaires for measuring psychological variables. Results: SEUS construct validity was checked with Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) procedures. The long 48-item version was reduced to 14 items on which SEUS-14 is based. The final one-factor solution explained 57.7% of variance. The reliability measured with Cronbach’s α is very good. SEUS-14 correlates with BFAS and psychological measures of personality traits, narcissism, self-esteem and Behavioural Activation System, which confirms the scale criterion validity. Discussion: The presented study findings are consistent with the results of other research on Facebook or internet addiction. Regarding the construct validity, one-factor solution turned out to be the best while correlation analysis confirmed SEUS criterion validity. Conclusions: SEUS-14 has demonstrated good psychometric properties in a national sample of Polish adolescents. The measure, treated as a screening tool, can be used for scientific purpose though further studies on the broader use of the scale are necessary.
