Effect of Nature-Themed Recharge Room on Healthcare Workers' Level of Stress and Anxiety.

Objective: To determine if there is a difference in stress and anxiety before and after the use of the nature-themed recharge room.

Background: Psychological support measures have been noted to be relevant to nurses; however, the effect of the pandemic on the healthcare workers' emotional and psychological well-being led to urgent calls to implement psychological support measures more widely.

Methods: The study utilized a 1-group pretest and posttest design.

Cell differentiation modifies the p53 transcriptional program through a combination of gene silencing and constitutive transactivation.

The p53 transcription factor is a master regulator of cellular responses to stress that is commonly inactivated in diverse cancer types. Despite decades of research, the mechanisms by which p53 impedes tumorigenesis across vastly different cellular contexts requires further investigation. The bulk of research has been completed using in vitro studies of cancer cell lines or in vivo studies in mouse models, but much less is known about p53 action in diverse non-transformed human tissues.

Reactivation of Simian Varicella Virus in Rhesus Macaques after CD4 T Cell Depletion.

Rhesus macaques intrabronchially inoculated with simian varicella virus (SVV), the counterpart of human varicella-zoster virus (VZV), developed primary infection with viremia and rash, which resolved upon clearance of viremia, followed by the establishment of latency. To assess the role of CD4 T cell immunity in reactivation, monkeys were treated with a single 50-mg/kg dose of a humanized monoclonal anti-CD4 antibody; within 1 week, circulating CD4 T cells were reduced from 40 to 60% to 5 to 30% of the total T cell population and remained low for 2 months. Very low viremia was seen only in some of the treated monkeys.
