Understanding Mass Panic and Other Collective Responses to Threat and Disaster.

While mass panic (and/or violence) and self-preservation are often assumed to be the natural response to physical danger and perceived entrapment, the literature indicates that expressions of mutual aid are common and often predominate, and collective flight may be so delayed that survival is threatened. In fact, the typical response to a variety of threats and disasters is not to flee but to seek the proximity of familiar persons and places; moreover, separation from attachment figures is a greater stressor than physical danger. Such observations can be explained by an alternative "social attachment" model that recognizes the fundamentally gregarious nature of human beings and the primacy of attachments.

Understanding health disparities affecting people of West Central African descent in the United States: An evolutionary perspective.

Human populations adapting to diverse aspects of their environment such as climate and pathogens leave signatures of genetic variation. This principle may apply to people of West Central African descent in the United States, who are at increased risk of certain chronic conditions and diseases compared to their European counterparts. Less well known is that they are also at reduced risk of other diseases.

Patient survey examining the experience of care of a hospital-based opt-out tobacco dependency treatment service (the CURE Project).

Introduction: Treating tobacco dependency in patients admitted to hospital is a key priority in the National Health Service long-term plan. This service evaluation assessed the perception, needs and experience of care within an opt-out hospital-based tobacco dependency treatment service (the Conversation, Understand, Replace, Experts and Evidence Base (CURE) team) in North-West England.

Methods: A survey was offered to all eligible patients between 1 July 2020 and 30 September 2020.

Activation of the viral sensor oligoadenylate synthetase 2 (Oas2) prevents pregnancy-driven mammary cancer metastases.

Background: The interferon response can influence the primary and metastatic activity of breast cancers and can interact with checkpoint immunotherapy to modulate its effects. Using N-ethyl-N-nitrosourea mutagenesis, we found a mouse with an activating mutation in oligoadenylate synthetase 2 (Oas2), a sensor of viral double stranded RNA, that resulted in an interferon response and prevented lactation in otherwise healthy mice.

Methods: To determine if sole activation of Oas2 could alter the course of mammary cancer, we combined the Oas2 mutation with the MMTV-PyMT oncogene model of breast cancer and examined disease progression and the effects of checkpoint immunotherapy using Kaplan-Meier survival analysis with immunohistochemistry and flow cytometry.
