Latino health and well-being are crucial to the growth and vibrancy of rural areas across the United States, particularly at a time when the demographics of many rural communities are transitioning from minority Latino to majority Latino populations. This manuscript details the findings of a study that explored the health and healthcare benefit status of 524 Latino households in rural Indiana during the COVID-19 pandemic. Via 20-minute, door-to-door interviews conducted by bilingual researchers, survey participants answered questions about access to healthcare services and benefits, dietary and safety habits, medical issues, and vaccination status.

Article Synopsis
  • Early social isolation in rats influences dopamine signaling and reward behaviors, with distinct changes in different brain regions (mPFC and NAc) depending on housing conditions.* -
  • Group-housed rats showed increased dopamine in the mPFC during feeding, while isolated rats had elevated levels in the NAc, indicating long-lasting effects of social conditions on dopamine dynamics.* -
  • Microinjections of dopamine or cocaine into the mPFC could reverse deficits in reward behavior in isolated rats, highlighting the critical role of social interactions in shaping reward-related neural responses.*

General control nonderepressible 2 (GCN2) protein kinase is a cellular stress sensor within the tumor microenvironment (TME), whose signaling cascade has been proposed to contribute to immune escape in tumors. Herein, we report the discovery of cell-potent GCN2 inhibitors with excellent selectivity against its closely related Integrated Stress Response (ISR) family members heme-regulated inhibitor kinase (HRI), protein kinase R (PKR), and (PKR)-like endoplasmic reticulum kinase (PERK), as well as good kinome-wide selectivity and favorable PK. In mice, compound engages GCN2 at levels ≥80% with an oral dose of 15 mg/kg BID.
