Objective: We studied patterns in health care access between Latino and non-Latino White adults according to citizenship status before and after the American Rescue Plan Act (ARPA) of 2021 was enacted to determine whether inequities changed.
Methods: This study used 2019-2022 National Health Survey Interview data. Differences in predicted probabilities from logistic regression models were used to estimate changes in health care access outcomes (any insurance coverage, private insurance coverage, delaying care due to cost, and having a usual source of care) among Latino citizens, Latino noncitizens, and non-Latino White citizens in periods before and after ARPA's enactment (2019-2020 vs 2021-2022).
Article Synopsis
- Presence-absence surveys are often used to track rare species, but their effectiveness for confirming breeding activity needs validation.
- The study focused on the Marbled Murrelet, a threatened seabird in the Pacific, assessing whether these surveys could successfully identify active nesting sites amid difficult conditions.
- Results indicated that while presence-absence surveys may help suggest potential nesting habitats, they are not reliable for pinpointing actual nesting sites, requiring many repeated surveys to accurately assess breeding activity.
Molecular mechanisms underlying qualitative resistance have been intensively studied. In contrast, although quantitative disease resistance (QDR) is a common, durable, and broad-spectrum form of immune responses in plants, only a few related functional analyses have been reported. The atypical kinase Resistance related kinase 1 (RKS1) is a major regulator of QDR to the bacterial pathogen Xanthomonas campestris (Xcc) and is positioned in a robust protein-protein decentralized network in Arabidopsis (Arabidopsis thaliana).

Microvascular insulin delivery to myocytes is rate limiting for the onset of insulin-stimulated muscle glucose uptake. The structural integrity of capillaries of the microvasculature is regulated, in part, by a family of transmembrane adhesion receptors known as integrins, which are composed of an α and a β subunit. The integrin β1 (itgβ1) subunit is highly expressed in endothelial cells (ECs).

- * The study focused on the integrin β1 subunit in endothelial cells, revealing that its absence led to impaired microvascular function and glucose uptake in response to insulin.
- * Findings showed that mice lacking endothelial integrin β1 had decreased capillary flow and density, resulting in compromised insulin-mediated glucose delivery, highlighting its importance for proper muscle function.
