Aims-Although research shows that sexual minority women report high rates of lifetime sexual victimization and high rates of hazardous drinking, investigators have yet to explore the relationships between sexual victimization and hazardous drinking in this population. In addition, because rates of these problems may vary within the sexual minority population, we examined and compared relationships between sexual victimization and hazardous drinking in exclusively heterosexual and sexual minority (mostly heterosexual, bisexual, mostly lesbian and exclusively lesbian) women.Method-Data from 548 participants in the National Study of Health and Life Experiences of Women and 405 participants in the Chicago Health and Life Experiences of Women study were pooled to address these relationships. We compared hazardous drinking, childhood sexual abuse (CSA), adult sexual assault (ASA), and revictimization (both CSA and ASA) across the five sexual identity subgroups. We then fit a multilevel general linear model to examine group differences in the relationships between hazardous drinking and sexual victimization and to test for potential interactions between victimization and identity on hazardous drinking.Results-Sexual minority women reported higher levels of hazardous drinking and higher rates of CSA and sexual revictimization than did exclusively heterosexual women. Revictimization was NIH-PA Author ManuscriptNIH-PA Author Manuscript NIH-PA Author Manuscript the strongest predictor of hazardous drinking among women who identified as mostly heterosexual and mostly lesbian.Conclusions-This study extends previous research by examining associations between sexual victimization and hazardous drinking in heterosexual and sexual minority women and by exploring within-group variations in these associations among sexual minority women. Higher rates of lifetime sexual victimization and revictimization may help to explain sexual minority women's heightened risk for hazardous drinking. The findings highlight the need for additional research that examines the meanings of sexual identity labels to more fully understand differences in risk within groups of sexual minority women as well as how sexual identity may affect responses to and interpretations of sexual victimization.
Recently, graphene-based membranes have been extensively studied, represented by two distinct research directions: (i) creating pores in graphene basal plane and (ii) engineering nanochannels in graphene layers. Most simulation results predict that porous graphene membranes can be much more selective and permeable than current existing membranes, also evidenced by some experimental results for gas separation and desalination. In addition, graphene oxide has been widely investigated in layered membranes with two-dimensional nanochannels, showing very intriguing separation properties. This review will cover state-of-the-art of graphene-based membranes, and also provide a material guideline on future research directions suitable for practical membrane applications.
Respiratory diseases and lung injuries are one of the leading causes of death in the world. One critical component of these diseases is exaggerated inflammatory response. The recently discovered inflammasome is believed to play a key role in inflammation. The inflammasome is an oligomer of intracellular proteins that, once activated by an insult or damage signal, produces mature cytokines from the interleukin-1 family that mediate an inflammatory response. Previous research has provided evidence that suggests the role of the inflammasome in the pathogenesis of many chronic respiratory diseases and acute lung injuries, such as transfusion-related acute lung injury, ventilator-induced lung injury, asthma, chronic obstructive pulmonary disease and pulmonary fibrosis. This article summarizes recent research on the inflammasome and reviews proposed molecular models of the role of the inflammasome in several prominent lung diseases and injuries.
As water molecules permeate ultrafast through carbon nanotubes (CNTs), many studies have prepared CNTs-based membranes for water purification as well as desalination, particularly focusing on high flux membranes. Among them, vertically aligned CNTs membranes with ultrahigh water flux have been successfully demonstrated for fundamental studies, but they lack scalability for bulk production and sufficiently high salt rejection. CNTs embedded in polymeric desalination membranes, i.e., polyamide thin-film composite (TFC) membranes, can improve water flux without any loss of salt rejection. This improved flux is achieved by enhancing the dispersion properties of CNTs in diamine aqueous solution and also by using cap-opened CNTs. Hydrophilic CNTs were prepared by wrapping CNT walls via bio-inspired surface modification using dopamine solution. Cap-opening of pristine CNTs is performed by using a thermo-oxidative process. As a result, hydrophilic, cap-opened CNTs-embedded polyamide TFC membranes are successfully prepared, which show much higher water flux than pristine polyamide TFC membrane. On the other hand, less-disperse, less cap-opened CNTs-embedded TFC membranes do not show any flux improvement and rather lead to lower salt rejection properties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
