Our findings support that IPV is prevalent across genders and sexual orientations. Clinical guidelines for IPV screening should be expanded to include TGNC individuals and not just cisgender women. Future research could explore the complex patterns by which individuals of different genders are at increased risk for different types of IPV, and investigate the best ways to screen TGNC patients and support TGNC survivors.
Facile dip-coating method to fabricate robust polypyrrole thin film coating on thermal insulation polypropylene membrane with solar vapor generation efficiency of 72%.
When a swollen, thermoresponsive polymer gel is heated in a solvent bath, it expels solvent and deswells. When this heating is slow, deswelling proceeds homogeneously, as observed in a toroid-shaped gel that changes volume while maintaining its toroidal shape. By contrast, if the gel is heated quickly, an impermeable layer of collapsed polymer forms and traps solvent within the gel, arresting the volume change. The ensuing evolution of the gel then happens at fixed volume, leading to phase separation and the development of inhomogeneous stress that deforms the toroidal shape. We observe that this stress can cause the torus to buckle out of the plane, via a mechanism analogous to the bending of bimetallic strips upon heating. Our results demonstrate that thermodynamic instabilities, i.e., phase transitions, can be used to actuate mechanical deformation in an extreme thermodynamics of materials.
This paper reports the use of microfluidic approaches for the fabrication of yeastosomes (yeast-celloidosomes) based on self-assembly of yeast cells onto liquid-solid or liquid-gas interfaces. Precise control over fluidic flows in droplet- and bubble-forming microfluidic devices allows production of monodispersed, size-selected templates. The general strategy to organize and assemble living cells is to tune electrostatic attractions between the template (gel or gas core) and the cells via surface charging. Layer-by-Layer (LbL) polyelectrolyte deposition was employed to invert or enhance charges of solid surfaces. We demonstrated the ability to produce high-quality, monolayer-shelled yeastosome structures under proper conditions when sufficient electrostatic driving forces are present. The combination of microfluidic fabrication with cell self-assembly enables a versatile platform for designing synthetic hierarchy bio-structures.
Sexual orientation related health disparities are well documented. Sexual minority men appear to be at risk for mental health problems due to the stress they experience in establishing and maintaining a minority sexual identity. These mental health issues may combine synergistically and lead to higher medical costs to society. We examine whether sexual minority specific syndemic indicators were associated with higher health care costs, health care utilization, or the risk of being HIV-infected. Health care consumers at a community health center (N = 1211) completed a brief screening questionnaire collected over 12 months. Self-reported data were linked with participants’ clinical billing records. Adjusted logistic regression models identified that four syndemic indicators (suicidality, substance use, childhood sexual abuse, and intimate partner violence) were each significantly related to each other. Multiple syndemics significantly predicted higher medical care utilization and cost, and were associated with 2.5 times the risk of being HIV-infected (OR 2.49, 95% CI 1.45–4.25). Syndemic indicators did not significantly predict the number of mental health visits or costs per patient. These results confirm and extend earlier findings by relating syndemics to health services use and costs for sexual minority men.
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.
