Macrophages are innate immune cells that are known for their extreme plasticity, enabling diverse phenotypes that lie on a continuum. In a simplified model, they switch between pro-inflammatory (M1) and anti-inflammatory (M2) phenotypes depending on surrounding microenvironmental cues, which have been implicated in disease outcomes. Although considerable research has been focused on macrophage response to biochemical cues and mechanical signals, there is a scarcity of knowledge surrounding their behavior in response to shear stress.

Article Synopsis
  • - The MCM motor, initially inactive as a double hexamer, is crucial for DNA replication and becomes activated through the recruitment of proteins GINS and Cdc45 during the S-phase of the cell cycle.
  • - Research reveals that the metazoan protein Downstream neighbor of Son (DONSON) plays a key role in the assembly of active CMG helicases by delivering GINS to MCM, though the specific effects on the MCM structure were unclear prior to this study.
  • - Using cryoelectron microscopy on Xenopus egg extracts, the study identifies a double CMG complex connected by a DONSON dimer, showing that this tethering is vital for DNA replication, with mutations in DONSON linked to issues in human

Faithful cell division is the basis for the propagation of life and DNA replication must be precisely regulated. DNA replication stress is a prominent endogenous source of genome instability that not only leads to ageing, but also neuropathology and cancer development in humans. Specifically, the issues of how vertebrate cells select and activate origins of replication are of importance as, for example, insufficient origin firing leads to genomic instability and mutations in replication initiation factors lead to the rare human disease Meier-Gorlin syndrome.

Employing a case of a state transportation agency, we examine how complex institutions which integrate outsourcing within a bureaucratic process adapt to environmental regulatory changes. In 2012, two endangered species of bats were located outside of their established ranges in northern Georgia. These discoveries required the Georgia Department of Transportation (GDOT) to comply with a new set of federal regulations relating to those species when developing its projects.

Objectives: Targeting remission in rheumatoid arthritis (RA) improves health-related quality of life (HRQoL) and disability. However, the impacts of different remission criteria and durations and their frequencies are uncertain. Our observational study assessed these factors.
