A variety of practices have recently emerged which relate to both video games and gambling. These range from opening loot boxes, to esports betting, real-money video gaming, token wagering, and social casino spending. It is unknown either how harmful or how widespread many of these activities are. A sample of 1,081 adults from the UK aged 18+ was therefore recruited. This sample was purposively recruited via quota sampling to represent the UK population in terms of sex, age, and ethnicity. Engagement in all forms of gaming-related practices were significantly associated with both problem gambling and disordered gaming. A total of 18.5% of the sample had engaged in these activities at least once in the new year. These results suggest a convergent ecosystem of practices that relate to both video games and gambling. Engagement in each of these activities is linked to problem gambling. However, it remains unclear whether engagement in these activities causes problem gambling.

Substitution can be defined as the consciously motivated choice to use one drug, either licit or illicit, instead of another, due to perceptions of cost, availability, safety, legality, substance characteristics, and substance attributions. Substitution represents a potential risk to drug users, mainly when substitutes are of higher potency and toxicity. selleck chemicals This study offers a basic conceptualization of illicit substitution behavior and describes substitution patterns among users of two highly prevalent drugs of abuse-heroin and cannabis.

Here, 592 high-risk drug users undergoing pharmacological and psycho-social treatment were interviewed. Patients were asked questions about current drug use, lifetime substitution, and substitution patterns. Descriptive statistics, chi-square tests of independence, and multinomial logistic regressions were used to identify and test correlates of substitution patterns for heroin and cannabis.

Of the 592 drug users interviewed, 448 subjects (75.7%) reported having substitutethadone provides evidence for the ongoing diversion of this substance from Opioid Maintenance Treatment Centers, while the prominence of substitution of synthetic cannabinoids among dual-diagnosis patients should be regarded as an ongoing risk to patients that needs to be addressed by clinicians. Analysis of additional substitution patterns should provide further valuable insights into the behavior of drugusers.

This systematic review aimed to investigate the psychometric properties of the school health's assessment tools in primary schools through COSMIN Risk of Bias checklist. We examined the studies that have addressed the measurement properties of school-health instruments to give a clear overview of the quality of all available tools measuring school health in primary schools. This systematic review was registered in PROPERO with the Registration ID CRD42020158158.

Databases of EBSCOhost, PubMed, ProQuest, Wily, PROSPERO, and OpenGrey were systematically searched without any time limitation to find all full-text English journal articles studied at least one of the COSMIN checklist measurement properties of a school-health assessment tool in primary schools. The instruments should be constructed based on a school health model. The eligible studies were assessed by COSMIN Risk of Bias checklist to report their quality of methodology for each measurement property and for the whole study by rating high, moderateeloping school health assessment tools.The antioxidant system (AOS) maintains the optimal concentration of reactive oxygen species (ROS) in a cell and protects it against oxidative stress. In plants, the AOS consists of seven main classes of antioxidant enzymes, low-molecular antioxidants (e.g., ascorbate, glutathione, and their oxidized forms) and thioredoxin/glutaredoxin systems which can serve as reducing agents for antioxidant enzymes. The number of genes encoding AOS enzymes varies between classes, and same class enzymes encoded by different gene copies may have different subcellular localizations, functional loads and modes of evolution. These facts hereafter reinforce the complex nature of AOS regulation and functioning. Further studies can describe new trends in the behavior and functioning of systems components, and provide new fundamental knowledge about systems regulation. The system is revealed to have a lot of interactions and interplay pathways between its components at the subcellular level (antioxidants, enzymes, ROS level, and hormonal and transcriptional regulation). These facts should be taken into account in further studies during the AOS modeling by describing the main pathways of generating and utilizing ROS, as well as the associated signaling processes and regulation of the system on cellular and organelle levels, which is a complicated and ambitious task. Another objective for studying the phenomenon of the AOS is related to the influence of cell dynamics and circadian rhythms on it. Therefore, the AOS requires an integrated and multi-level approach to study. We focused this review on the existing scientific background and experimental data used for the systems biology research of the plant AOS.Potato (Solanum tuberosum L.) is the third most economically important crop in the world and has a high nutritional value. In this study, the in vitro culture response of four widely grown in Kazakhstan potato cultivars, Astanalyk, Monument Kunaev, Tokhtar, and Aksor, was investigated using stem and leaf explants. Published protocols were evaluated and optimized to develop a more efficient protocol for the regeneration of plants from local potato cultivars in tissue culture, which is a prerequisite to facilitate potato genome modification. The explants were cultured on solid Murashige and Skoog medium supplemented with different concentrations and combinations of zeatin, 6-benzylaminopurine (BAP), gibberellic acid (GA3), 1-naphthaleneacetic acid (NAA) and indole-3-acetic acid (IAA). The maximum regeneration was induced from the stem internodal explants. A significant effect of the explant source on direct regeneration was confirmed with statistical analysis. The number of shoots obtained from the internode was 10.
