TL;DR: Using a sample of financial restatements prompted by accounting irregularities and identified by the U.S. Government Accountability Office, empirical support is found for both incentive and relative performance influences on financial statement misrepresentation.
Abstract: Despite the many undesirable outcomes of corporate misconduct, scholars have an inadequate understanding of corporate misconduct's causes and mechanisms. We extend the behavioral theory of the firm, which traditionally assumes away the possibility of firm impropriety, to develop hypotheses predicting that top management incentive compensation and poor organizational performance relative to aspirations increase the likelihood of financial misrepresentation. Using a sample of financial restatements prompted by accounting irregularities and identified by the U.S. Government Accountability Office, we find empirical support for both incentive and relative performance influences on financial statement misrepresentation.

TL;DR: If systematic and thorough presection sampling of the mediastsinal and hilar lymph nodes is negative, mediastinal lymph node dissection does not improve survival in patients with early stage non-small cell lung cancer, but these results are not generalizable to patients staged radiographically or those with higher stage tumors.

TL;DR: The data show that histone tail acetylation is required directly for DNA repair and suggest that a related human HAT complex may function similarly.
Abstract: Although the acetylation of histones has a well-documented regulatory role in transcription, its role in other chromosomal functions remains largely unexplored. Here we show that distinct patterns of histone H4 acetylation are essential in two separate pathways of double-strand break repair. A budding yeast strain with mutations in wild-type H4 acetylation sites shows defects in nonhomologous end joining repair and in a newly described pathway of replication-coupled repair. Both pathways require the ESA1 histone acetyl transferase (HAT), which is responsible for acetylating all H4 tail lysines, including ectopic lysines that restore repair capacity to a mutant H4 tail. Arp4, a protein that binds histone H4 tails and is part of the Esa1-containing NuA4 HAT complex, is recruited specifically to DNA double-strand breaks that are generated in vivo. The purified Esa1-Arp4 HAT complex acetylates linear nucleosomal arrays with far greater efficiency than circular arrays in vitro, indicating that it preferentially acetylates nucleosomes near a break site. Together, our data show that histone tail acetylation is required directly for DNA repair and suggest that a related human HAT complex may function similarly.

TL;DR: Observations suggest that transcriptional regulation occurs by multiple mechanistically linked covalent modifications of histones, including serine 10 to alanine in the histone H3 tail.

TL;DR: The myocardium remains viable for a prolonged period in many patients with acute infarction and an occluded infarct-related artery and Viability appears to be associated with the presence of collateral blood flow within the infarCT bed.
Abstract: Background. We hypothesized that successful reperfusion of an occluded infarct-related coronary artery even late after acute myocardial infarction would result in improved regional wall motion and that such improvement might be related to the presence of collateral blood flow within the infarct bed. Methods. We assessed regional wall motion by two-dimensional echocardiography at base line and one month after angioplasty was attempted in the occluded infarct-related artery in 43 patients who had had a myocardial infarction two days to five weeks earlier. A wall-motion score was assigned to each patient on a five-point scale (from 1 [normal function] to 5 [dyskinesia]). The percentage of the infarct bed perfused by collateral flow was assessed with myocardial contrast echocardiography. Results. In the 41 patients who had abnormal wall motion at base line, improvement in function was noted in 25 (78 percent) of the 32 in whom angioplasty was successful, as compared with only 1 (11 percent) of the 9 ...
