Purpose Waterpipe tobacco smoking (WTS) is currently a serious and growing public health threat in the world, especially in adolescents and young women. The aim of the study was to explore sociocultural factors contributing to WTS among adolescents and young adult women in Iran. Methods This qualitative study was conducted from August 2017 to January 2019 in Isfahan and Hamadan cities, Iran; it included 13-30-year-old females with experience of WTS. For data collection, in-depth semi-structured personal interviews were conducted at participants' preferred time and place. Concurrent with data collection, data were analysed through conventional content analysis. Results The study participants described the various sociocultural factors contributing to WTS. These factors were categorized into four following main categories waterpipe glamorization by its producers and sellers, media advertisement or silence, common sociocultural traditions, and governmental policies and regulations. Conclusion A wide range of sociocultural factors affects WTS among Iranian adolescents and young adult women. Therefore, interdisciplinary multidimensional strategies are needed for WTS management and prevention among these at-risk groups. Public education, strict supervision of tobacco import, export, and selling, ample employment opportunities for young people and effective leisure time management are essential to reduce WTS.Abbreviation WTS Waterpipe Tobacco Smoking; MPOWER Monitor tobacco use and prevention policies, Protect people from tobacco smoke, Offer help to quit tobacco use, Warn about the dangers of tobacco, Enforce bans on tobacco advertising, promotion and sponsorship, Raise taxes on tobacco.Research indicates that youths are particularly susceptible to peer influence and that identifying with substance using peer groups predicts substance use. Today, youth spend more time interacting with distal peer groups via the Internet and have increased access to online drug cultures. Theoretically, this should have important implications for substance use. This study employs a nationally representative sample of U.S. youth (n = 1212), ages 15-25 years old, to examine whether online peer group identification and social media homophily predict substance use. Colcemid Results indicate that online belonging and social media homophily are associated with some forms of substance use. While these factors were not significantly associated with regular marijuana or alcohol use among those who had initiated use, they predicted regular stimulant and opioid use among substance users. This suggests that online peer groups may promote progression into more problematic forms of substance use. Additional analyses of adolescent and young adult subgroups revealed important similarities and differences among the groups. The findings imply several directions for future research, and suggest that prevention policies and programs should continue to consider the role of online peers, and the Internet generally, in substance use initiation, escalation, and prevention. The importance of actively involving patient and public members throughout the different stages of palliative care and health research projects is widely acknowledged, however patient and public involvement work rarely considers insight from children and young people. Although this is becoming increasingly recognised in other areas of research, there is currently no structured guidance on how to best involve children and young people in palliative care research. To plan and deliver a Young People's Advisory Group in palliative care and health research at a secondary school. Attending an after-school 'Health and Social Research Methods Club' for 11 weeks benefitted children and researchers. Children were taught about data collection methods, data analysis and ethics in health research and used these skills to provide valuable feedback which has been implemented in current palliative care research projects. Children took part in considered discussions around palliative care topics and enjoyed attending the group. This project has equipped researchers with skills and provided a structured template for future Young People's Advisory Groups, ensuring the unique voices of children and young people are considered and valued in future palliative care research.This project has equipped researchers with skills and provided a structured template for future Young People's Advisory Groups, ensuring the unique voices of children and young people are considered and valued in future palliative care research.Laccases have enormous potential as promising 'green' biocatalysts in environmental applications including wastewater treatment and polluted soil bioremediation. The catalytic oxidation reaction they perform uses only molecular oxygen without other cofactors, and the only product after the reaction is water. The immobilization of laccase offers several improvements such as protected activity and enhanced stability over free laccase. In addition, the reusability of immobilized laccase is adistinct advantage for future applications. This review covers the sources of and progress in laccase research, and discusses the different methodologies of laccase immobilization that have emerged in the recent 5-10 years, as well as its applications to environmental fields, and evaluates these emerging technologies.

Study participants were 165 primary school children, aged 6-9 years, divided into three groups based on their visual acuity with the Snellen chart (a) non-amblyopia, (b) corrected amblyopia, and (c) non-corrected amblyopia. We assessed the children's motor competence with the Motor Competence Assessment battery (MCA) and their physical activity with the Physical Activity Questionnaire for Older Children (PAQ-C). The non-amblyopia group presented significantly better motor competence on the MCA than either the corrected amblyopia group or the non-corrected amblyopia group; there were no statistically significant motor differences between the two amblyopia subgroups. Amblyopia versus non-amblyopia differences on the MCA were mainly in stability and locomotor components, involving dynamic balance and the change of spatial position and direction of movement, but not in the manipulative component (ball throwing velocity and ball kicking velocity).
