Theoretically Suggested Divergent Predictions for Pornography Use, Religiosity, and Permissive Sexual Attitudes.

Pornography and attitude change studies most often adopt a sexual scripting (SS) perspective. The moral incongruence (MI) perspective on pornography has gained prominence in recent years, however, and may lead to differential predictions from the SS approach. Specifically, a detailed reading of MI and SS papers reveals the potential for discrepant predictions about the effect of pornography on sexual permissiveness, one of the most studied outcomes in pornography research. From an SS perspective, pornography use increases sexual permissiveness, but the preexisting traditional sexual scripts of the religious lessen the magnitude of this effect. Alternatively, the MI perspective implies the possibility that religious persons become more opposed to permissive sexuality as a result of their pornography use, as a way to mitigate the cognitive dissonance they feel for engaging in a sexual behavior proscribed by their faith tradition. The present study explored these divergent possibilities using nationally representative U.S. data. Across four meta-samples and four indicators of sexual permissiveness, religious nonviewers of pornography were the least sexually permissive, followed by religious viewers, nonreligious nonviewers, and nonreligious viewers. These results were robust over time and maintained after adjusting for demographics. For theorizing about pornography, religiosity, and sexual permissiveness, these results suggest that an SS approach may be preferable to an MI approach. The importance of continued research using both the SS and MI perspectives is discussed, however, emphasizing that the present study extrapolated a potential prediction from MI rather than a formal postulate put forth by the model's creators.

Relationship between childhood sexual abuse and attitudes toward premarital sexual permissiveness among middle school students in Luzhou, China.

BACKGROUND: In recent years, the number of adolescents engaging in premarital sex has increased, and an increasing number of childhood sexual abuse (CSA) cases have been reported in China. Many studies have indicated that CSA has a well-established association with risky sexual activities. However, only a limited number of studies have explored possible reasons for this association among middle school students, a population that may engage in premarital sex, which is critical for the development of interventions to prevent risky sexual behavior. Based on random samples of middle school students from a Chinese city, this article investigated the relationship between CSA and students' premarital sexual permissiveness (PSP). METHODS: In a cross-sectional study conducted between 2016 and 2017 in Luzhou, China, 2292 middle school and high school students aged 12-18 years were recruited by multistage random sampling. All students were administered anonymous questionnaires. Multiple linear regression and binary logistic regression analyses were conducted to analyze the relationship between CSA and PSP. RESULTS: The prevalence of CSA was 15.4% (354/2292; 95% CI: 14-16.9%). A higher percentage of male respondents (18.2%) than female respondents (12.9%) had experienced CSA. A positive association between CSA and PSP was found among students. Respondents who had suffered CSA exhibited greater PSP, and this relationship was observed in the male sample, female sample and the total student sample in Luzhou (ß = - 3.76, P < 0.05; ß = - 2.79, P < 0.05; and ß = - 2.84, P < 0.05, respectively). Respondents who had suffered CSA were also more likely to express a double standard about premarital sex (odds ratio [OR] =1.41, P < 0.05), especially among male students (odds ratio [OR] =1.63, P < 0.05). CONCLUSIONS: Sex differences in CSA and the relationship between CSA and PSP were significant among this large sample of middle school students in Luzhou (China). The findings suggest that experiencing CSA may be closely related to youth attitudes toward premarital sex, especially among males. Therefore, it is important to emphasize the prevention of CSA and provide adolescent reproductive health programs to reduce the impact of CSA on sexual cognition and attitude, prevent premarital sex and promote positive attitudes toward sexual equality for middle school students.

Does parental permissiveness toward cigarette smoking and alcohol use influence illicit drug use among adolescents? A longitudinal study in seven European countries.

PURPOSE: Adolescents' perceptions of parental norms may influence their substance use. The relationship between parental norms toward cigarette and alcohol use, and the use of illicit substances among their adolescent children is not sufficiently investigated. The purpose of this study was to analyze this relationship, including gender differences, using longitudinal data from a large population-based study. METHODS: The present study analyzed longitudinal data from 3171 12- to 14-year-old students in 7 European countries allocated to the control arm of the European Drug Addiction Prevention trial. The impact of parental permissiveness toward cigarettes and alcohol use reported by the students at baseline on illicit drug use at 6-month follow-up was analyzed through multilevel logistic regression models, stratified by gender. Whether adolescents' own use of cigarette and alcohol mediated the association between parental norms and illicit drug use was tested through mediation models. RESULTS: Parental permissive norms toward cigarette smoking and alcohol use at baseline predicted adolescents' illicit drug use at follow-up. The association was stronger among boys than among girls and was mediated by adolescents' own cigarette and alcohol use. CONCLUSION: Perceived parental permissiveness toward the use of legal drugs predicted adolescents' use of illicit drugs, especially among boys. Parents should be made aware of the importance of norm setting, and supported in conveying clear messages of disapproval of all substances.

The Prospective Effects of Parents' and Friends' Approval of Drinking on Simultaneous Alcohol and Marijuana Use during College.

Background: Recent reports indicate that simultaneous alcohol and marijuana (SAM) use is a growing health concern among college students. As SAM use consists of both alcohol and marijuana, risk factors associated with either can serve as plausible targets by prevention efforts to reduce SAM use. Objectives: To explore this, the current study investigated the direct and indirect effects of two established risk factors for drinking on SAM use: perceived parental permissiveness toward drinking and friends' approval toward drinking (injunctive norms). Method: Incoming first-year students (N = 470) reported parental permissiveness, injunctive norms, alcohol use, and SAM use at baseline (T1) and 5 months later (T2). SAM use was assessed again 15 months post-baseline (T3). Path analysis was conducted to examine whether T2 variables mediated relationships between T1 variables and T3 SAM use. Results: Results revealed that T2 student alcohol use mediated the effects of T1 parental permissiveness, injunctive norms, and alcohol use on T3 SAM use. Conclusions/Importance: Findings from this study extend research on SAM use by identifying perceived parental permissiveness and injunctive drinking norms as risk factors for SAM use through their effects on alcohol use. Based on these findings, it is plausible that parent-based interventions and interventions targeting peer injunctive norms during the first year of college could be used to effectively prevent or reduce SAM use.

Type I Interferon Receptor Signaling Drives Selective Permissiveness of Astrocytes and Microglia to Measles Virus during Brain Infection.

Fatal neurological syndromes can occur after measles virus (MeV) infection of the brain. The mechanisms controlling MeV spread within the central nervous system (CNS) remain poorly understood. We analyzed the role of type I interferon (IFN-I) receptor (IFNAR) signaling in the control of MeV infection in a murine model of brain infection. Using organotypic brain cultures (OBC) from wild-type and IFNAR-knockout (IFNARKO) transgenic mice ubiquitously expressing the human SLAM (CD150) receptor, the heterogeneity of the permissiveness of different CNS cell types to MeV infection was characterized. In the absence of IFNAR signaling, MeV propagated significantly better in explant slices. In OBC from IFNAR-competent mice, while astrocytes and microglia were infected on the day of explant preparation, they became refractory to infection with time, in contrast to neurons and oligodendrocytes, which remained permissive to infection. This selective loss of permissiveness to MeV infection was not observed in IFNARKO mouse OBC. Accordingly, the development of astrogliosis related to the OBC procedure was exacerbated in the presence of IFNAR signaling. In the hippocampus, this astrogliosis was characterized by a change in the astrocyte phenotype and by an increase of IFN-I transcripts. A proteome analysis showed the upregulation of 84 out of 111 secreted proteins. In the absence of IFNAR, only 27 secreted proteins were upregulated, and none of these were associated with antiviral activities. Our results highlight the essential role of the IFN-I response in astrogliosis and in the permissiveness of astrocytes and microglia that could control MeV propagation throughout the CNS.IMPORTANCE Measles virus (MeV) can infect the central nervous system (CNS), with dramatic consequences. The mechanisms controlling MeV invasion of the CNS remain ill-defined since most previous data were obtained from postmortem analysis. Here, we highlight for the first time the crucial role of the type I interferon (IFN-I) response not only in the control of CNS invasion but also in the early permissiveness of glial cells to measles virus infection.

Parents Allowing Drinking Is Associated With Adolescents' Heavy Alcohol Use.

BACKGROUND: Using intergenerational prospective data from the Millennium Cohort Study (MCS), we examine whether parents allowing 14-year-olds to drink alcohol is associated with greater likelihood of early adolescents' heavy episodic drinking (i.e., lifetime, rapid escalation from first drink, and frequent past year), beyond shared risk factors for parental alcohol permissiveness and adolescent alcohol use. METHODS: The MCS is a unique, contemporary, nationally representative study with mother, father, and child data from infancy through age 14 years (n = 11,485 children and their parents). In a series of multivariate logistic regressions, we estimated whether teenagers whose parents allowed them to drink alcohol (16% of parents said "yes") faced an elevated likelihood of heavy alcohol use at age 14, controlling for a large host of likely child and parent confounders measured when children were age 11. To further assess plausible intergenerational associations of parental alcohol permissiveness and offspring heavy alcohol use, coarsened exact matching (CEM) was used to match 14-year-olds whose parents allowed them to drink alcohol with teens whose parents did not allow them to drink on these childhood antecedent variables. RESULTS: Adolescents whose parents allowed them to drink had higher odds of heavy drinking (odds ratio [OR] = 2.40; 95% confidence interval [CI] = 1.96 to 2.94), rapidly escalating from initiation to heavy drinking (OR = 1.94; CI = 1.52 to 2.49), and frequent heavy drinking (OR = 2.32; 1.73 to 3.09), beyond child and parent confounders and using CEM methods. CONCLUSIONS: Adolescents who were allowed to drink were more likely to have transitioned quickly from their first drink to consuming 5 or more drinks at 1 time and to drinking heavily 3 or more times in the past year. Given well-documented harms of adolescent heavy drinking, these results do not support the idea that parents allowing children to drink alcohol inoculates them against alcohol misuse.

SARS-CoV-2 and the safety margins of cell-based biological medicinal products.

With the pandemic emergence of SARS-CoV-2, the exposure of cell substrates used for manufacturing of medicines has become a possibility. Cell lines used in biomanufacturing were thus evaluated for their SARS-CoV-2 susceptibility, and the detection of SARS-CoV-2 in culture supernatants by routine adventitious virus testing of fermenter harvest tested.

The interaction between parental behavior and motivations to drink alcohol in high school students.

BACKGROUND: Alcohol use during adolescence has been predicted by motives to drink or abstain, as well as parental attitudes to youth drinking. As peers can provide access and opportunities to drink, permissiveness of peers' parents toward alcohol is also of importance. OBJECTIVES: We examined whether adolescent alcohol use is predicted by motives to drink or abstain, strictness of one's own parents, alcohol permissiveness by peers' parents, and an interaction between these factors. METHOD: A sample of high school students from the Pacific Northwest (N = 1056; 49% girls; mage = 15.6) completed alcohol use and parenting measures, the Drinking Motives Questionnaire-Revised, and the Motives for Abstaining from Alcohol Questionnaire. A zero-inflated negative binomial regression model examined the combined influence of motives, parent's strictness, and peer's parents' permissiveness on past month use. RESULTS: Parental permissiveness was associated with higher rates of drinking among students with low (but not high) conformity motives and motives to abstain. Higher parental permissiveness was associated with higher rates of drinking among students with low (but not high) coping motives. CONCLUSIONS: Our results demonstrate that parental strictness regarding teen alcohol use extends beyond the family unit to influence adolescent drinking in the broader social network. Parents may have a limited capacity to deter drinking through setting rules and expectations for adolescents who are motived to drink to conform but such limit setting maybe particularly helpful for youth with fewer motives to abstain.

Quantitative Proteomic Analysis of Simian Primary Hepatocytes Reveals Candidate Molecular Markers for Permissiveness to Relapsing Malaria Plasmodium cynomolgi.

A major obstacle impeding malaria research is the lack of an in vitro system capable of supporting infection through the entire liver stage cycle of the parasite, including that of the dormant forms known as hypnozoites. Primary hepatocytes lose their liver specific functions in long-term in vitro culture. The malaria parasite Plasmodium initiates infection in hepatocyte. This corresponds to the first step of clinically silent infection and development of malaria parasite Plasmodium in the liver. Thus, the liver stage is an ideal target for development of novel antimalarial interventions and vaccines. However, drug discovery against Plasmodium liver stage is severely hampered by the poor understanding of host-parasite interactions during the liver stage infection and development. In this study, tandem mass tag labeling based quantitative proteomic analysis is performed in simian primary hepatocytes cultured in three different systems of susceptibility to Plasmodium infection. The results display potential candidate molecular markers, including asialoglycoprotein receptor, apolipoproteins, squalene synthase, and scavenger receptor B1 (SR-BI) that facilitate productive infection and full development in relapsing Plasmodium species. The identification of these candidate proteins required for constructive infection and development of hepatic malaria liver stages paves the way to explore them as therapeutic targets.

A longitudinal exploration of the relationship between pornography use and sexual permissiveness in female and male adolescents.

INTRODUCTION: There are concerns that pornography use increases adolescents' sexual permissiveness, leading to sexual risk-taking. In contrast to most longitudinal explorations of the relationship between adolescent pornography use and sexual permissiveness, which were carried out in highly liberal and permissive societies, we aimed to re-assess the target relationship in a more traditional, highly religious society. METHODS: Informed by the social learning and selective exposure theoretical underpinnings, we used two independent panels of Croatian female and male adolescents (on average 16 years old) to assess the association over 18 and 24 months. Online surveying was used in the Zagreb (n = 372) and classroom-based surveying in the Rijeka panels (n = 753). RESULTS: Participants reported relatively low levels of permissiveness, but substantial pornography use-particularly adolescent men. Contrary to earlier studies, we observed no significant paths leading from pornography use to sexual permissiveness. The paths leading from sexual permissiveness to pornography use were significant only among female participants in the Zagreb sample and male participants in the Rijeka sample. However, significant and positive covariances between the two constructs suggested the role of unobserved variables. CONCLUSIONS: In line with the selective exposure hypothesis and the integrative models, this study's findings challenge the notion that pornography use increases sexual permissiveness among adolescents. Although this is reassuring, comprehensive sexuality education and media literacy programs remain important tasks for educational policy in the Information age.

Molecular epidemiology of Avian Rotaviruses Group A and D shed by different bird species in Nigeria.

BACKGROUND: Avian rotaviruses (RVs) cause gastrointestinal diseases of birds worldwide. However, prevalence, diversity, epidemiology and phylogeny of RVs remain largely under-investigated in Africa. METHODS: Fecal samples from 349 birds (158 symptomatic, 107 asymptomatic and 84 birds without recorded health status) were screened by reverse transcription PCR to detect RV groups A and D (RVA and RVD). Partial gene sequences of VP4, VP6, VP7 and NSP4 for RVA, and of VP6 and VP7 for RVD were obtained and analyzed to infer phylogenetic relationship. Fisher's exact test and logistic regression were applied to identify factors potentially influencing virus shedding in chickens. RESULTS: A high prevalence of RVA (36.1%; 126/349) and RVD (31.8%; 111/349) shedding was revealed in birds. In chickens, RV shedding was age-dependent and highest RVD shedding rates were found in commercial farms. No negative health effect could be shown, and RVA and RVD shedding was significantly more likely in asymptomatic chickens: RVA/RVD were detected in 51.9/48.1% of the asymptomatic chickens, compared to 18.9/29.7% of the symptomatic chickens (p < 0.001/p = 0.01). First RVA sequences were obtained from mallard ducks (Anas platyrhynchos) and guinea fowls (Numida meleagris). Phylogenetic analyses illustrated the high genetic diversity of RVA and RVD in Nigerian birds and suggested cross-species transmission of RVA, especially at live bird markets. Indeed, RVA strains highly similar to a recently published fox rotavirus (RVA/Fox-tc/ITA/288356/2011/G18P[17]) and distantly related to other avian RVs were detected in different bird species, including pigeons, ducks, guinea fowls, quails and chickens. CONCLUSION: This study provides new insights into epidemiology, diversity and classification of avian RVA and RVD in Nigeria. We show that cross-species transmission of host permissive RV strains occurs when different bird species are mixed.

Determination of the Cell Permissiveness Spectrum, Mode of RNA Replication, and RNA-Protein Interaction of Zika Virus.

BACKGROUND: Two lineages of Zika virus (ZIKV) have been classified according to the phylogenetic analysis: African and Asian lineages. It is unclear whether differences exist between the two strains in host cell permissiveness, this information is important for understanding viral pathogenesis and designing anti-viral strategies. METHODS: In the present study, we comparatively studied the permissive spectrum of human cells for both the African (MR766) and Asian strains (PRVABC59) using an RNA in situ hybridization (RISH) to visualize RNA replication, an immunofluorescence technology, and a western blot assay to determine viral protein production, and a real-time RT-PCR to examine viral RNA multiplication level. The experiments were undertaken in the condition of cell culture. RESULTS: We identified several human cell lines, including fibroblast, epithelial cells, brain cells, stem cells, and blood cells that are susceptible for the infection of both Asian and African strains. We did not find any differences between the MR766 and the PRVABC59 in the permissiveness, infection rate, and replication modes. Inconsistent to a previous report (Hamel et al. JVI 89:8880-8896, 2015), using RISH or real-time RT-PCR, we found that human foreskin fibroblast cells were not permissive for ZIKV infection. Instead, human lung fibroblast cells (MRC-5) were fully permissive for ZIKV infection. Surprisingly, a direct interaction of ZIKV RNA with envelop (E) protein (a structure protein) was demonstrated by an RNA chromatin immunoprecipitation (ChIP) assay. Three binding sites were identified in the ZIKV RNA genome for the interaction with the E protein. CONCLUSION: Our results imply that the E protein may be important for viral RNA replication, and provide not only the information of ZIKV permissiveness that guides the usage of human cells for the ZIKV studies, but also the insight into the viral RNA-E protein interaction that may be targeted for intervention by designing small molecule drugs.

Bidirectional Relationships Between Parenting Processes and Deviance in a Sample of Inner-City African American Youth.

The current study assessed for bidirectional relationships among supportive parenting (knowledge), negative parenting (permissiveness), and deviance in a sample (N = 5,325) of poor, inner-city African American youth from the Mobile Youth Survey (MYS) over 4 years. Cross-lagged path analysis provided evidence of significant bidirectional paths among parenting processes (knowledge and permissiveness) and deviance over time. Follow-up multigroup tests provided only modest evidence of dissimilar relationships by sex and by developmental periods. The findings improve our understanding of developmental changes between parenting behaviors and deviance during adolescence and extended current research of the bidirectionality of parent and child relationships among inner-city African American youth.

Dressing an existential wound (DEW) - a new model for long-term care following disasters.

BACKGROUND: Presence, concern, compassion and universal or ontological unity between human beings have emerged as crucial to the healthy development of people who have experienced disasters. AIM AND OBJECTIVES: The aim of this article was to present a new model for long-term care following disasters. The objective of the model was to contribute to the readiness for long-term care following disasters in professionals and nonprofessionals as a result of their understanding of the model. DESIGN: A longitudinal qualitative study of Swedish tourists affected by the South East Asian tsunami in 2004 is the empirical base for this clinical model, which was developed within the framework of caring science. METHODS: A hermeneutic method was used. RESULTS: The model is based on the assumption that life issues are an important aspect of long-term follow-up after a disaster. The term 'life issues' refers to the following: existential questioning of life's content, values and priorities; people's relationships with each other; and the importance of health, suffering, love and death. Life issues also refer to the way in which survivors form a new understanding of life after a disaster experience. Existential care is based on a charitable attitude of compassion and mercy towards one's fellows, be they professionals, families or wider society. By presenting eight theses, the model provides an approach based on compassion that works as an existential dressing for survivors of disaster. CONCLUSIONS: The model gives a knowledge base and approach for the long-term care of survivors, including practical advice.

The structure of the amygdala associates with human sexual permissiveness: evidence from voxel-based morphometry.

Sexual behavior is a critical function of human procreation. Despite previous studies that investigated the neural mechanisms of basic human physiological sexual functions, the neural mechanisms that underlie individual differences in human sexual permissiveness remain unknown. We used voxel-based morphometry and a questionnaire (scale for sexual attitudes) to measure sexual permissiveness to investigate the gray matter and white matter structural correlates of sexual permissiveness. Sexual permissiveness was negatively correlated with regional gray matter density of the structures involving the right amygdala and surrounding areas, and positively correlated with regional white matter density of the white matter area that spread around the left amygdala to the hypothalamus area. There were no gender-specific relationships in the neural correlates of our findings. These findings suggest that structural variations in regions that play key roles in the basic physiological aspects of human sexuality underlie individual complex sexual attitudes in social life.

Impact of aeration rate on the transfer range of antibiotic-resistant plasmids during manure composting.

Conjugative plasmids are important vectors of mobile antibiotic resvistance genes (ARGs), facilitating their horizontal transfer within the environment. While composting is recognized as an effective method to reduce antibiotics and ARGs in animal manure, its impact on the bacterial host communities containing antibiotic-resistant plasmids remains unclear. In this study, we investigated the permissiveness of bacterial community during composting when challenged with multidrug-resistant conjugative RP4 plasmids, employing Pseudomonas putida as the donor strain. Ultimately, this represents the first exploration of the effects of aeration rates on the range of RP4 plasmid transfer hosts. Transconjugants were analyzed through fluorescent reporter gene-based fluorescence-activated cell sorting and Illumina sequencing. Overall, aeration rates were found to influence various physicochemical parameters of compost, including temperature, pH, total organic matter, total nitrogen, and potassium. Regarding RP4 plasmid host bacteria, the dominant phylum was determined to shift from Bacteroidetes in the raw material to Proteobacteria in the compost. Notably, a moderate-intensity aeration rate (0.05 L/min/L) was found to be more effective in reducing the diversity and richness of the RP4 plasmid host bacterial community. Following composting, the total percentage of dominant transconjugant-related genera decreased by 66.15-76.62%. Ultimately, this study determined that the aeration rate negatively impacts RP4 plasmid host abundance primarily through alterations to the environmental factors during composting. In summary, these findings enhance our understanding of plasmid host bacterial communities under varying composting aeration rates and offer novel insights into preventing the dissemination of ARGs from animal manure to farmland.

SARS-CoV-2 Establishes a Productive Infection in Hepatoma and Glioblastoma Multiforme Cell Lines.

Severe acute respiratory syndrome associated coronavirus 2 (SARS-CoV-2) emerged at the end of 2019 and rapidly caused a pandemic that led to the death of >6 million people due to hypercoagulation and cytokine storm. In addition, SARS-CoV-2 triggers a wide array of pathologies, including liver dysfunction and neurological disorders. It remains unclear if these events are due to direct infection of the respective tissues or result from systemic inflammation. Here, we explored the possible infection of hepatic and CNS cell lines by SARS-CoV-2. We show that even moderate expression levels of the angiotensin-converting enzyme 2 (ACE2) are sufficient for productive infection. SARS-CoV-2 infects hepatoma Huh7.5 and HepG2 cells but not non-transformed liver progenitor or hepatocyte/cholangiocyte-like HepaRG cells. However, exposure to the virus causes partial dedifferentiation of HepaRG cells. SARS-CoV-2 can also establish efficient replication in some low-passage, high-grade glioblastoma cell lines. In contrast, embryonal primary astrocytes or neuroblastoma cells did not support replication of the virus. Glioblastoma cell permissiveness is associated with defects in interferon production. Overall, these results suggest that liver dysfunction during COVID-19 is not due to infection of these tissues by SARS-CoV-2. Furthermore, tumors may potentially serve as reservoirs for the virus during infection.

A Systematic Review of the Association between Parenting Styles and Narcissism in Young Adults: From Baumrind's Perspective.

The concept 'parenting styles' has been widely examined to understand the etiology of narcissism for decades. This study aimed to systematically review the empirical research literature regarding the association between perceived parenting styles and narcissism. In this study, Ebscohost, Wiley Online Library, Taylor&Francis, Springer Link, PubMed, PsycNet, ScienceDirect, and Google Scholar databases were searched using identified keywords. An extensive database search resulted in 75 identified publications. Of these, 60 were scrutinized, and in the end, ten studies were included in the review for data synthesis. To reach a common conceptualization on the parenting styles, the results were evaluated based on Baumrind's typology. As a result of this systematic review, we can conclude that there is a relationship between narcissism and parenting styles. In particular, perceived permissive parenting was positively correlated with narcissism. However, the relationship between narcissism and other parenting styles is more complex. Therefore, more high-quality empirical studies are needed to investigate the relationship between parenting and narcissism.

Taking alcohol from one's parents' home without permission as a risk factor for greater alcohol and marijuana use during the transition into college.

While adolescents and underage emerging adults typically obtain alcohol from social sources (e.g., parents, friends, parties), taking alcohol from the home without permission is not well understood. The current study investigated plausible individual characteristics associated with taking alcohol from one's parents' home without permission and associations between taking alcohol and drinking, alcohol consequences, and marijuana use. Two cohorts of alcohol-experienced underage emerging adults (N = 562) completed a web-based survey pre-college matriculation. Participants reported sources of alcohol (friend, mother, father, party, took it from home); drinking; consequences; marijuana use (ever and past 30 days); age of alcohol initiation; symptoms of depression, anxiety, and stress; parental modeling of drinking; and demographic information. Results revealed that taking alcohol was significantly associated with several of the measures examined here (e.g., having obtained alcohol from friends, parents, and parties; earlier age of alcohol initiation; parental modeling of alcohol). Having taken alcohol from the home without permission and obtained it from friends were uniquely associated with increased odds of typical weekly drinking, consequences, and marijuana use in the past 30 days when controlling for all other variables assessed in this study (including drinking, in the consequences and marijuana models). Parent-based interventions targeting adolescents and emerging adults should inform parents of the risks associated with taking alcohol from the home and obtaining it from friends. Further, parents should also be informed that supplying their adolescent with alcohol or modeling drinking may increase the likelihood that they take alcohol from their home.

SARS-CoV-2 strain wars continues: Chemical and thermodynamic characterization of live matter and biosynthesis of Omicron BN.1, CH.1.1 and XBC variants.

SARS-CoV-2 has during the last 3 years mutated several dozen times. Most mutations in the newly formed variants have been chemically and thermodynamically characterized. New variants have been declared as variants under monitoring. The European Centre for Disease Prevention and Control has suggested the hypothesis that the new BN.1, CH.1.1 and XBC variants could have properties similar to those of VOC. Thermodynamic properties of new variants have been reported in this manuscript for the first time. Gibbs energy of biosynthesis, as the driving force for viral multiplication, is less negative for the new variants than for the earlier variants. This indicates that the virus has evolved towards decrease in pathogenicity, which leads to less severe forms of COVID-19.
