The AIDS and Cancer Specimen Resource (ACSR) is a network of four regional biospecimen repositories and a technical core in the United States and South Africa. Its mission is to acquire, store, and distribute HIV-associated malignancy specimens and related clinical data to support translational research. At the outset of the COVID-19 pandemic, it became apparent that existing ACSR Standard Operating Procedures (SOPs) were not sufficient to ensure long-term maintenance and integrity of inventories during periods of extended shutdown. The ACSR needed an administrative SOP for situations pertaining to epidemics/pandemics. The ACSR Quality Working Group (QWG), comprised of representatives from each of the five ACSR sites and an external member who directs a large university medical center biorepository, addressed the issue. To understand the individual problems the sites faced, questions were developed to query each of the six QWG sites' contingency plans to cover this type of emergency, the amount of work allowed onsite and by whom, the challenges sites experienced, and the lessons learned to assist with future similar situations, while remaining consistent with the existing IRB protocols. Reported challenges spanned all activities of classical biobanks and differed within the geographical locations of the sites and the local COVID-19 infection rate. Review of the responses to the questions revealed that the general shutdown of society external to the biorepositories presented them with a homogeneous collection of problems, limitations, and needs. This led to creating an SOP that addresses planning for pandemic emergencies, scaling down of activities, shutting down, and reopening plans. The ACSR QWG sites now have a structured response SOP for their sites, including guidance on how to develop and implement an emergency shutdown and reopening plan. The complete SOP is publicly available on the ACSR website.

Spreading depolarization (SD) temporarily shuts down neural processing in mammals and insects. Age is a critical factor for predicting the consequences of SD in humans. We investigated the effect of aging in an insect model of SD and explored the contribution of oxidative stress.

Plants use seasonal cold to time the transition to reproductive development. Short- and long-term cold exposure is registered via parallel transcriptional shutdown and Polycomb-dependent epigenetic silencing of the major flowering repressor locus (). The cold-induced antisense transcripts () determine the dynamics of transcriptional shutdown, but the thermosensory mechanisms are still unresolved.

In response to the SARS-CoV-2 pandemic, the United States declared a state of emergency and implemented large-scale shutdowns and public health initiatives to prevent overwhelming public resources. The success of these prevention methods remains unresolved as restrictions and implementation varied from national, state, and local levels. Despite national and local regulations, individual adherence to preventative guidelines presented an additional layer of variability.
