To examine the Acquired Preparedness Model using a behavioral impulsivity facet and positive marijuana expectancies to examine direct and indirect effects on marijuana use and related problems.
250 college students (61.7% female, 54% white) recruited from a southeastern university.
Participants completed an online survey of delay reward discounting, marijuana expectancies, consideration of future consequences, and marijuana-related outcomes.
Delay reward discounting and consideration of future consequences related to marijuana-related problems, but not marijuana use. However, positive marijuana expectancies did not mediate the relation between impulsivity and marijuana outcomes. ABT-199 inhibitor
These results emphasize delay reward discounting and consideration of future consequences as important factors associated with marijuana-related problems. Interventions aimed at decreasing delay reward discounting and augmenting future orientation may be effective in college students who report light to moderate marijuanntions aimed at decreasing delay reward discounting and augmenting future orientation may be effective in college students who report light to moderate marijuana use. Future studies would benefit from longitudinal study designs using multiple impulsivity measures among light and heavy users.Elder abuse is a preventable problem. Presently, little is known about this phenomenon in Middle Eastern settings. The purpose of this study was to explore elder abuse in Beirut, Lebanon from different stakeholders' points of view with a focus on identifying behaviors that are considered to be abusive to older adults and predisposing factors. Focus group discussions were carried out with 88 home- and institution-based older adults, their family members and caregivers, and with 49 stakeholders (medical professionals, institution directors, government officials). Results showed that behaviors considered abusive among Lebanese participants were comparable to reports from international studies. The most commonly mentioned risk factors were history of abuse in a seemingly dysfunctional family followed by caregivers' lack of acceptance of the physical changes that accompany aging. The response to elder abuse requires a multidimensional approach that spans protective policies to increase care providers' awareness about the physiologic changes of aging as well as concerted efforts to correct misinformation about the hidden problem of elder abuse.AbstractAquatic hypoxic events are increasing in frequency and intensity as concentrations of nutrients, such as nitrate, continue to rise from human activities. Many fish species can alter their behavior and physiology to cope with drops in oxygen, but these compensatory strategies may be compromised under high levels of nitrate pollution. Hence, we investigated whether exposure to elevated nitrate concentrations affects key behavioral (avoidance and aquatic surface respiration [ASR]) and physiological (hemoglobin and hematocrit levels, ventilation frequency, and burst and prolonged swimming performance) responses of fish to mitigate the impacts of acute hypoxia. Juvenile silver perch (Bidyanus bidyanus) were exposed to one of three nitrate concentrations (0, 50, or 100 mg NO3- L-1) for 3 wk, after which behavioral and physiological responses of fish to progressive hypoxia were assessed. Fish exposed to nitrate utilized ASR at a higher threshold of partial pressure of oxygen during progressive hypoxia compared with control animals but did not alter behavioral avoidance of low oxygen levels. In these nitrate-exposed fish, the early onset of ASR behaviors is likely a behavioral, compensatory strategy to cope with nitrate-induced physiological disruptions, namely, increases in ventilation frequency and lower levels of hemoglobin and hematocrit. The physiological constraints placed by nitrate and acute hypoxia exposures manifested to lower the swimming performance of silver perch. Collectively, these data suggest that exposure to elevated nitrate is likely to disrupt key behavioral and physiological strategies used by fish to cope with short-term hypoxia.Zona-free somatic cell transfer (SCT) and embryo aggregation increase throughput and efficiency of cloned embryo and offspring production, respectively, but both approaches have not been widely adopted. Cloning efficiency is further improved by cell cycle coordination between the interphase donor cell and metaphase-arrested recipient cytoplast. This commonly involves inclusion of caffeine and omission of calcium to maintain high mitotic cyclin-dependent kinase activity and low calcium levels, respectively, in the nonactivated cytoplast. The aim of our study was to integrate these various methodological improvements into a single work stream that increases sheep cloning success. We show that omitting calcium during zona-free SCT improved blastocyst development from 6% to 13%, while caffeine treatment reduced spontaneous oocyte activation from 17% to 8%. In a retrospective analysis, morula aggregation produced high morphological quality blastocysts with better in vivo survival to term than nonaggregated controls (15% vs. 9%), particularly after vitrification (14% vs. 0%). By combining cytoplast cell cycle control with zona-free embryo reconstruction and aggregation, this novel SCT protocol maximizes the benefits of vitrification by producing more cryoresilient blastocysts. The presented cloning methodology is relatively easy to operate and further increases throughput and efficiency of cloned embryo and offspring production. Integration of additional reprogramming steps or alternate donor cells is straightforward, providing a flexible workflow that can be adapted to changing experimental requirements.
To describe rates and identify factors associated with human papillomavirus (HPV) vaccination among young adult males in college/university settings.

Study was reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Five electronic databases were searched for empirical studies published between 2009 and 2019 and focused on predictors for HPV vaccine uptake. Studies' methodological quality scores ranged between 12 and 23 points.

Five hundred and ninety eight titles/abstracts and 154 full-text articles were screened. Eighteen studies were included for final analysis. Results depicted participants' attitude, perceived susceptibility, severity, benefits, and barriers in receiving HPV vaccine. Many participants did not perceive themselves to be susceptible to HPV infection, and barriers to receiving HPV vaccine outweighed benefits. HPV knowledge and vaccination rates were relatively low among respondents.

Prevention campaigns that increase knowledge, promote positive attitudes, change perception of susceptibility, and address barriers may result in higher HPV vaccination rates among males in college/university settings.
