This essay examines that decision and places it in historical context based on the author’s expertise gained through years of working within NARA at the Franklin D. Roosevelt Presidential Library and Museum and writing about the early history of NARA and the presidential library system. The essay explores the many ways in which the failure to build an Obama Library adversely impacts researcher access to important historical information, damages the quality of museum exhibits at a privately run Obama museum, threatens the presidential library system as we know it, and ultimately impairs our democracy.

North American prairie pothole wetlands are known to be important carbon stores. As a result there is interest in using wetland restoration and conservation programs to mitigate the effects of ...increasing greenhouse gas concentration in the atmosphere. However, the same conditions which cause these systems to accumulate organic carbon also produce the conditions under which methanogenesis can occur. As a result prairie pothole wetlands are potential hotspots for methane emissions. We examined change in soil organic carbon density as well as emissions of methane and nitrous oxide in newly restored, long-term restored, and reference wetlands across the Canadian prairies to determine the net GHG mitigation potential associated with wetland restoration. Our results indicate that methane emissions from seasonal, semi-permanent, and permanent prairie pothole wetlands are quite high while nitrous oxide emissions from these sites are fairly low. Increases in soil organic carbon between newly restored and long-term restored wetlands supports the conclusion that restored wetlands sequester organic carbon. Assuming a sequestration duration of 33 years and a return to historical SOC densities we estimate a mean annual sequestration rate for restored wetlands of 2.7 Mg C ha

Human mutations in Nkx2-5 lead to progressive cardiomyopathy and conduction defects via unknown mechanisms. To define these pathways, we generated mice with a ventricular-restricted knockout of ...Nkx2-5, which display no structural defects but have progressive complete heart block, and massive trabecular muscle overgrowth found in some patients with Nkx2-5 mutations. At birth, mutant mice display a hypoplastic atrioventricular (AV) node and then develop selective dropout of these conduction cells. Transcriptional profiling uncovered the aberrant expression of a unique panel of atrial and conduction system-restricted target genes, as well as the ectopic, high level BMP-10 expression in the adult ventricular myocardium. Further, BMP-10 is shown to be necessary and sufficient for a major component of the ventricular muscle defects. Accordingly, loss of ventricular muscle cell lineage specification into trabecular and conduction system myocytes is a new mechanistic pathway for progressive cardiomyopathy and conduction defects in congenital heart disease.
A unique how-to guide on surgical management of strabismus from top experts in the field! Strabismus correction is the third most common ophthalmic surgery in the US, with 1.2 million procedures ...performed each year. Strabismus Surgery by renowned pediatric ophthalmologist Irene Ludwig provides comprehensive coverage of strabismus treatment - featuring state-of-the-art techniques based on recent anatomical research and discoveries. Throughout the text and accompanying videos, an impressive group of contributors share clinical pearls and firsthand knowledge. Recent research shows that strabismus has a mechanical etiology more frequently than previously thought, and that by directly correcting the mechanical defects, more targeted correction is possible than with traditional approaches. Accordingly, the book is organized by mechanism rather than strabismic deviations and patterns. Presented in four parts, each of which is further delineated by sections, this unique textbook includes 36 chapters starting with the fascinating history of strabismus surgery and concluding with future possible treatments. Key Highlights * New surgical techniques designed to correct muscle displacements and muscle defects related to abnormalities of the extraocular muscle pulleys and intermuscular bands * Recognition and repair of stretched scar and flap tear * A section dedicated to CNS-related causes of strabismus discusses state-of-the-art surgical approaches for conditions including nystagmus and cranial nerve palsies * A comprehensive summary of injection techniques using botulinum toxin and bupivacaine to correct strabismus, particularly in otherwise inoperable conditions * Ninety strabismus surgery videos demonstrate a full spectrum of basic to advanced techniques * Remarkable illustrations beautifully capture the complex anatomy of the eye muscles and pulleys The mechanistic approaches described in this outstanding resource will help trainees and seasoned ophthalmologists achieve more precise and lasting results.

According to the Harvard Business Review, much information sharing happens through short, informal discussions during the workday-and that's what I've seen. In Microsoft's 2022 New Future of Work ...Report, researchers found that while remote work may improve job satisfaction, it can also lead to employees feeling socially isolated, guilty and trying to overcompensate. Moving from traditional places of employment to home offices decreases productivity and further isolates individuals who are already struggling-whether that is mentally, physically or for those who have difficulty achieving equitable representation.
