Decades of research have defined the function of interferon regulatory factors (IRFs) in the antiviral immune response. Interferon regulatory factor-1 (IRF-1) is the founding member of the IRF family, with recognized antiviral effects across diverse virus infections. While most antiviral activities of IRF-1 were defined in vitro, fewer studies examined the role of IRF-1 during viral infection of an intact host.

Background: Acute psychosocial stress activates the hypothalamic-pituitary-adrenal (HPA) axis and triggers the release of cortisol, a commonly used biomarker of stress reactivity. Yet only 25 % of studies have reported a correlation between cortisol and affective responses to stress. This study aimed to examine whether cortisol reactivity following an acute psychosocial stressor in the laboratory correlated with concurrent positive and negative affect in adolescents, and whether early life adversity (ELA) moderated this relationship.

The ability to stop already-initiated actions is paramount to adaptive behavior. In psychology and neuroscience alike, action-stopping is a popular model behavior to probe inhibitory control - the underlying cognitive control process that is purportedly vital to regulating thoughts and actions. Starting with seminal work in the 1990s, the frontocentral stop-signal P3 - an event-related potential derived from scalp EEG - has been proposed as a neurophysiological index of inhibitory control during action-stopping.

The paired watershed monitoring approach is widely used to investigate hydrologic processes and water quality, providing streamflow and water quality records for long-term trend analysis, as well as data for developing and testing hydrologic models. In this study we use 20 years of streamflow and water quality data, along with a watershed model, to examine sources of stream nutrients and their changes over time in two small streams within the New York City water supply system. We compare sources and trends in stream nitrate and dissolved phosphorus in the urbanized Amawalk watershed with those of the predominantly forested Boyd Corners watershed in the Croton system of reservoirs.

Passive cardiac monitoring has become synonymous with wearable technologies, necessitating patients to incorporate new devices into their daily routines. While this requirement may not be a burden for many, it is a constraint for individuals with chronic diseases who already have their daily routine. In this study, we introduce an innovative technology that harnesses the front-facing camera of smartphones to capture pulsatile signals discreetly when users engage in other activities on their device.

There are well-documented associations between life course changes and migration; yet, the occurrence, order, and timing of reasons for migrating are growing increasingly diverse. Migration following adverse life events, such as a divorce or an involuntary job loss, may be qualitatively distinct from migration undertaken for other reasons. Moves, especially long-distance moves, following adverse life events, may be defined more by seeking family and familiar locations.

Background: Several chemical studies described the physiological efficacy of 1,4- dihydropyridines (DHPs). DHPs bind to specific sites on the α1 subunit of L-type calcium channels, where they demonstrate a more pronounced inhibition of Ca2+ influx in vascular smooth muscle compared to myocardial tissue. This selective inhibition is the basis for their preferential vasodilatory action on peripheral and coronary arteries, a characteristic that underlies their therapeutic utility in managing hypertension and angina.

The most severe form of α-thalassemia results from loss of all four copies of α-globin. Postnatally, patients face challenges similar to β-thalassemia, including severe anemia and erythrotoxicity due to the imbalance of β-globin and α-globin chains. Despite progress in genome editing treatments for β-thalassemia, there is no analogous curative option for α-thalassemia.

Virus neutralization profiles against primary infection sera and corresponding antigenic cartography are integral part of the COVID-19 and influenza vaccine strain selection processes. Human single variant exposure sera have previously defined the antigenic relationships among SARS-CoV-2 variants but are now largely unavailable due to widespread population immunity. Therefore, antigenic characterization of future SARS-CoV-2 variants will require an animal model, analogous to using ferrets for influenza virus.

Person-centered planning has been shown to benefit people with disabilities and their quality of life. However, we have little knowledge of how person-centered planning can benefit staff and administration within a group home organization, as well as the extent to which it results in changes to organizational practices and procedures, as well as perceptions of people with disabilities. In this qualitative study, we explored the perspectives of organizational employees, an affiliating behavioral consultant, and residents with intellectual and developmental disabilities, taking into consideration key insights from person-centered planning consultant-coaches, to understand the effects of a person-centered planning initiative on the group home organization.
