Loss of AMPKalpha1 Triggers Centrosome Amplification via PLK4 Upregulation in Mouse Embryonic Fibroblasts.

Recent evidence indicates that activation of adenosine monophosphate-activated protein kinase (AMPK), a highly conserved sensor and modulator of cellular energy and redox, regulates cell mitosis. However, the underlying molecular mechanisms for AMPKα subunit regulation of chromosome segregation remain poorly understood. This study aimed to ascertain if AMPKα1 deletion contributes to chromosome missegregation by elevating Polo-like kinase 4 (PLK4) expression.

Agriculture emergencies: a primer for first responders.

Over the past several years, the primary focus of emergency preparedness has been on terrorism, and how a CBRNE event would directly affect human health. Limited emphasis has been placed on the direct (eg, zoonotic infections) and indirect (eg, mental health, financial loss) effects that an agricultural emergency event can have on human health outcomes, and how they relate to emergency preparedness. We critically reviewed the resources and information readily accessible to our target audience, emergency responders; the resources included military and civilian books, personal communications, internet sites, GAO reports, and peer-reviewed journals.

Spousal caregiving when the adult day services center is closed.

Of those spousal caregivers who identified a time when they most needed assistance, morning or afternoon time periods appeared to be most problematic. Spousal caregivers who reported receiving respite time on the weekends identified adult children as the informal support person most often available. However, more than half of the caregivers reported having no respite time during the weekend.

Chronic subclinical hypothermia: home care alert.

Chronic subclinical hypothermia poses a serious challenge to home health nurses because the condition may negatively impact the plan of care for very old and frail clients. This article provides a review of age-associated changes in thermoregulation, discusses the ways in which these changes may affect an elderly client's response to care, and offers home care interventions for individuals with chronic subclinical hypothermia.
