Perceptions of Molecular HIV Surveillance Among Men Who Have Sex with Men in the United States.

Expanding HIV cluster detection using molecular HIV surveillance (MHS) raises ethical and social concerns, which may impede HIV outbreak detection and response as well as deter people living with HIV from seeking care. This underscores the need for effective communication strategies. We examined two methods for explaining MHS among men who have sex with men (MSM) living with HIV and at-risk without HIV in the United States.

Blurring Boundaries: A Proposed Research Agenda for Ethical, Legal, Social, and Historical Studies at the Intersection of Infectious and Genetic Disease.

Contemporary understanding of the mechanisms of disease increasingly points to examples of "genetic diseases" with an infectious component and of "infectious diseases" with a genetic component. Such blurred boundaries generate ethical, legal, and social issues and highlight historical contexts that must be examined when incorporating host genomic information into the prevention, outbreak control, and treatment of infectious diseases.

EMhub: a web platform for data management and on-the-fly processing in scientific facilities.

Most scientific facilities produce large amounts of heterogeneous data at a rapid pace. Managing users, instruments, reports and invoices presents additional challenges. To address these challenges, EMhub, a web platform designed to support the daily operations and record-keeping of a scientific facility, has been introduced.

Dynamic metal coordination controls chemoselectivity in radical halogenases.

The activation of inert C( )-H bonds by non-heme Fe enzymes plays a key role in metabolism, epigenetics, and signaling, while providing a powerful biocatalytic platform for the chemical synthesis of molecules with increased complexity. In this context, Fe /α-ketoglutarate-dependent radical halogenases represent a broadly interesting system, as they are uniquely capable of carrying out transfer of a diverse array of bound anions following C-H activation. Here, we provide the first experimental evidence that bifurcation of H-atom abstraction and radical rebound is driven both by the ability of a dynamic metal coordination sphere to reorganize as well as by a second-sphere hydrogen-bond network where only two residues (Asn224 and Ile151) are necessary and sufficient.
