Introduction: Observational studies have found that higher iron levels are associated with an increased risk of diabetes mellitus. Given the limitations of causal inferences from observational studies and the expensive and time-consuming nature of randomized controlled trials, Mendelian randomization analysis presents a reasonable alternative to study causal relationships. Previous MR analyses studying iron levels and diabetes have used indirect markers of iron levels, such as serum ferritin, and found conflicting results.

Nonalcoholic fatty liver disease (NAFLD) is one of the main causes of chronic liver disorders following liver transplantation. The prorenin receptor (PRR) plays a role in glucose and lipid metabolism, and the hepatic dysregulation of PRR is associated with the upregulation of several molecular pathways, such as the mammalian target of rapamycin (mTOR) and Peroxisome proliferator-activated receptor (PPAR) that promotes hepatic lipogenesis and leads to lipid accumulation in hepatocytes by upregulation of lipogenic genes. PRR inhibition leads to a reduction in the hepatic expression of sortilin-1 and low-density lipoprotein receptor (LDLR) levels and down-regulation of pyruvate dehydrogenase (PDH) and acetyl-CoA carboxylase (ACC) and reduces fatty acids synthesis in hepatocytes.

Nonhuman primate antigenic cartography of SARS-CoV-2.

Cell Rep

January 2025

Center for Virology and Vaccine Research, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA 02215, USA. Electronic address:

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.
