Early detection of obstructive sleep apnea in patients with atrial fibrillation.

Background: Obstructive sleep apnea (OSA) is an independent and modifiable risk factor for atrial fibrillation (AF) and correlates with a three-fold higher risk of incident AF. Although OSA is prevalent in patients with AF, it remains underdiagnosed. Guidelines for OSA screening are ambiguous.

Leadership Immersion and Aspiring Leader Programs Designed to Improve Nurses' Well-Being and Competence: Integral Features During the COVID-19 Pandemic.

Nurse leaders play integral roles in the health care system as they focus on patient quality of care and safety at a high level and lead teams of frontline staff. Nurse leadership turnover during COVID-19 poses challenges not only for continuity of patient care but also for organizations that may fail to meet their specific goals. When a nurse leader role is not filled, gaps in care delivery occur.

Utility of the Amborella trichopoda expansin superfamily in elucidating the history of angiosperm expansins.

Expansins form a superfamily of plant proteins that assist in cell wall loosening during growth and development. The superfamily is divided into four families: EXPA, EXPB, EXLA, and EXLB (Sampedro and Cosgrove in Genome Biol 6:242, 2005. doi: 10.

Genetic properties of the maize nested association mapping population.

Maize genetic diversity has been used to understand the molecular basis of phenotypic variation and to improve agricultural efficiency and sustainability. We crossed 25 diverse inbred maize lines to the B73 reference line, capturing a total of 136,000 recombination events. Variation for recombination frequencies was observed among families, influenced by local (cis) genetic variation.

Biochemical and molecular characterization of photosystem I deficiency in the NCS6 mitochondrial mutant of maize.

Interorganellar signaling interactions are poorly understood. The maize non-chromosomal stripe (NCS) mutants provide models to study the requirement of mitochondrial function for chloroplast biogenesis and photosynthesis. Previous work suggested that the NCS6 mitochondrial mutation, a cytochrome oxidase subunit 2 (cox2) deletion, is associated with a malfunction of Photosystem I (PSI) in defective chloroplasts of mutant leaf sectors (Gu et al.
