Structural and biochemical characterization of the mitomycin C repair exonuclease MrfB.

Mitomycin C (MMC) repair factor A (mrfA) and factor B (mrfB), encode a conserved helicase and exonuclease that repair DNA damage in the soil-dwelling bacterium Bacillus subtilis. Here we have focused on the characterization of MrfB, a DEDDh exonuclease in the DnaQ superfamily. We solved the structure of the exonuclease core of MrfB to a resolution of 2.

The context and development of the early relational health screen.

Early relational experiences are key drivers for developing social emotional capacities, educational achievement, mental health, physical health, and overall wellbeing. The child health sectors are committed to promotion, prevention, and early intervention that optimize children's health and development, often employing evidence-based screening as foundational practices. Despite a variety of validated parent-infant observational assessment tools, few are practical within busy practice settings, acceptable with all racial and ethnic groups and ready for universal adoption.

Progress in High-Speed Spin Testing of Superconducting Wire and Tapes for High-Field NMR Magnet Qualification.

This paper summarizes the status of a 3-year, NIH-funded research project to study the strength of high temperature superconductors under high circumferential hoop stress, in order to qualify these materials for high-field (> 1 GHz-class NMR magnets. The unique approach presented here is to spin test coils at high rotational speeds, approaching 100,000 rpm, in order to induce the necessary hoop stress. Thermal strain compatibility between the Bi-2212 wire and Inconel wire has been qualified, including thermal cycling.

Retropharyngeal Calcific Tendonitis in a Patient Seeking Chiropractic Care for Neck Pain: A Case Report.

Objective: The purpose of this report is to describe the evaluation and treatment of a patient initially presenting for chiropractic care of neck pain (NP) who was subsequently diagnosed with retropharyngeal calcific tendonitis (RCT).

Clinical Features: A 53-year-old woman presented to a chiropractic office with severe idiopathic NP, loss of cervical mobility, and intermittent painful swallowing. She had a motor vehicle accident 6 months before with NP that resolved within a week without treatment.
