Not enough: Medicaid expansion, medical debt, and cost avoidance in rural American Indian and Alaska Native households.

Purpose: Despite expanding health insurance coverage under the Patient Protection and Affordable Care Act (ACA), many Americans struggle with financial barriers to health care. Medicaid expansion was meant to help alleviate these barriers, particularly for rural communities, but has shown mixed results. The American Indian and Alaska Native (AI/AN) community, which faces both racial and geographic disparities, is a group that should benefit from Medicaid expansion.

adapted to steppe-desert climate extremes one million years ago.

Questions about when early members of the genus adapted to extreme environments like deserts and rainforests have traditionally focused on . Here, we present multidisciplinary evidence from Engaji Nanyori in Tanzania's Oldupai Gorge, revealing that thrived in hyperarid landscapes one million years ago. Using biogeochemical analyses, precise chronometric dating, palaeoclimate simulations, biome modeling, fire history reconstructions, palaeobotanical studies, faunal assemblages, and archeological evidence, we reconstruct an environment dominated by semidesert shrubland.

Outdoor mesoscale fabricated ecosystems: Rationale, design, and application to evapotranspiration.

The disparity in scale, complexity, and control level between laboratory experiments and field observational studies has shaped both the methodologies employed and the nature of the research questions pursued in ecology and hydrology. While lysimeters and fabricated ecosystems suitably fit in this gap, their use as mesoscale experimental facilities has not been fully explored because of the limited manipulating capabilities and integration with imaging and monitoring methods, particularly for soil functioning. The proposed fabricated ecosystem (4.

Changes in Dental Care Use Following Marital Status Change in the Health and Retirement Study.

Background And Objectives: Previous studies have indicated that married people are generally healthier than unmarried people, with lower mortality rates. Most work in this area has employed cross-sectional data, and few studies have examined change in marital status from married to unmarried as a potential social ecological determinant of dental health behavior. Here, we used longitudinal data to examine change in dental behavior over time following marital status change, and to explore whether self-reported gender may play a modifying role in any behavioral change.

Catalytic activities of wild-type C. elegans DAF-2 kinase and dauer-associated mutants.

DAF-2, the Caenorhabditis elegans insulin-like receptor homolog, regulates larval development, metabolism, stress response, and lifespan. The availability of numerous daf-2 mutant alleles has made it possible to elucidate the genetic mechanisms underlying these physiological processes. The DAF-2 pathway is significantly conserved with the human insulin/IGF-1 signaling pathway; it includes proteins homologous to human IRS, GRB-2, and PI3K, making it an important model to investigate human pathological conditions.
