Intrinsic p53 activation restricts gammaherpesvirus driven germinal center B cell expansion during latency establishment.

Gammaherpesviruses are DNA tumor viruses that establish lifelong latent infections in lymphocytes. For viruses such as Epstein-Barr virus and murine gammaherpesvirus 68, this is accomplished through a viral gene-expression program that promotes cellular proliferation and differentiation, especially of germinal center B cells. Intrinsic host mechanisms that control virus-driven cellular expansion are incompletely defined.

Vaccination with a Replication-Dead Murine Gammaherpesvirus Lacking Viral Pathogenesis Genes Inhibits WT Virus Infection.

Gammaherpesviruses are oncogenic pathogens that establish lifelong infections. There are no FDA-approved vaccines against Epstein-Barr virus or Kaposi sarcoma herpesvirus. Murine gammaherpesvirus-68 (MHV68) infection of mice provides a system for investigating of gammaherpesvirus pathogenesis and testing vaccine strategies.

Land Use Change Consistently Reduces α- But Not β- and γ-Diversity of Bees.

Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α-diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e.

Working Conditions for Burns Resident Doctors-Better Now than Ever?

Background: The work and life of a resident (or "junior") doctor has changed dramatically over the past 50 years. Descriptions of historic working conditions are usually anecdotal and tinted with nostalgia, but do today's burns and plastic surgery doctors feel working conditions have improved or declined over the last 50 years, and does this have an impact on recruitment and retention?

Methods: An interview was conducted with a retired surgeon who, in 1970, worked as a house surgeon (Year 2 doctor equivalent) in a burns unit for the pioneering burn surgeon Mr. Douglas MacGregor Jackson.
