RapA opens the RNA polymerase clamp to disrupt post-termination complexes and prevent cytotoxic R-loop formation.

Following transcript release during intrinsic termination, Escherichia coli RNA polymerase (RNAP) often remains associated with DNA in a post-termination complex (PTC). RNAPs in PTCs are removed from the DNA by the SWI2/SNF2 adenosine triphosphatase (ATPase) RapA. Here we determined PTC structures on negatively supercoiled DNA and with RapA engaged to dislodge the PTC.

Feasibility and acceptability for LION, a fully remote, randomized clinical trial within the VA for light therapy to improve sleep in Veterans with and without TBI: An MTBI2 sponsored protocol.

Sleep-wake disturbances frequently present in Veterans with mild traumatic brain injury (mTBI). These TBI-related sleep impairments confer significant burden and commonly exacerbate other functional impairments. Therapies to improve sleep following mTBI are limited and studies in Veterans are even more scarce.

Diabetes Mellitus Is Not a Risk Factor for Difficult Intubation Among Critically Ill Adults: A Secondary Analysis of Multicenter Trials.

Objectives: Diabetes mellitus has been associated with greater difficulty of tracheal intubation in the operating room. This relationship has not been examined for tracheal intubation of critically ill adults. We examined whether diabetes mellitus was independently associated with the time from induction of anesthesia to intubation of the trachea among critically ill adults.

Clinical Presentation of Adults with Traumatic Orthopedic Injuries Enrolled in a Multisite Psychosocial Trial.

Objectives: Traumatic orthopedic injuries are a top cause of hospital visits in the U.S. The Toolkit for Optimal Recovery (TOR) is a brief mind-body intervention that targets catastrophic thinking and pain anxiety following orthopedic injury.

Dementia Care Specialists Perspectives of Diagnosis and Early Psychosocial Care: A Qualitative Analysis of Focus Groups in Two Large Academic Medical Centers.

Background And Objective: Alzheimer's disease and related dementias (ADRDs) are progressive conditions that substantially impact individuals and families. Timely diagnosis and early support are critical for long-term adjustment. However, current dementia care models do not meet needs of patients and families.
