Updates to HIV transmission rate estimates along the HIV care continuum in the United States, 2019.
J Acquir Immune Defic Syndr
January 2025
Division of HIV Prevention, Centers for Disease Control and Prevention, Atlanta, GA, US at the time this research was undertaken. Current affiliation: Manhattan Associates, Atlanta GA.
Background: In 2019, there were an estimated 1.2 million persons with HIV (PWH) and 35,100 new infections in the United States. The HIV care continuum has a large influence on transmission dynamics.

JAMA Netw Open
January 2025
Division of Endocrinology, Diabetes and Metabolism, Mayo Clinic, Rochester, Minnesota.
Importance: Understanding the interplay between diabetes risk factors and diabetes development is important to develop individual, practice, and population-level prevention strategies.
Objective: To evaluate the progression from normal and impaired fasting glucose levels to diabetes among adults.
Design, Setting, And Participants: This retrospective community-based cohort study used data from the Rochester Epidemiology Project, in Olmsted County, Minnesota, on 44 992 individuals with at least 2 fasting plasma glucose (FPG) measurements from January 1, 2005, to December 31, 2017.
Iron limitation triggers roseoceramide biosynthesis and membrane remodeling in marine roseobacter.

Chemical communication between marine bacteria and their algal hosts drives population dynamics and ultimately determines the fate of major biogeochemical cycles in the ocean. To gain deeper insights into this small molecule exchange, we screened niche-specific metabolites as potential modulators of the secondary metabolome of the roseobacter, . Metabolomic analysis led to the identification of a group of cryptic lipids that we have termed roseoceramides.

The glucose-6-phosphatase (G6Pase) is an integral membrane protein that catalyzes the hydrolysis of glucose-6-phosphate (G6P) in the endoplasmic reticulum lumen and plays a vital role in glucose homeostasis. Dysregulation or genetic mutations of G6Pase are associated with diabetes and glycogen storage disease 1a (GSD-1a). Studies have characterized the biophysical and biochemical properties of G6Pase; however, the structure and substrate recognition mechanism of G6Pase remain unclear.

Phycobilisomes (PBS) are the major photosynthetic light-harvesting complexes in cyanobacteria and red algae. While the structures of PBS have been determined in atomic resolutions, how PBS are attached to the reaction centers of photosystems remains less clear. Here, we report that a linker protein (LcpA) is required for the attachment of PBS to photosystem II (PSII) in the cyanobacterium sp.
