BACKGROUND Several meta-analyses of randomized clinical trials have been performed to analyze whether double-row (DR) rotator cuff repair (RCR) provides superior clinical outcomes and structural healing compared to single-row (SR) repair. The purpose of this study was to sum up the results of meta-analysis comparing SR and DR repair with respect on clinical outcomes and re-tear rates. METHODS...

The purpose of this study was to assess mitochondrial function and glutathione (a mitochondrial antioxidant) in response to oxidative stress in mitochondria in vitro obtained from broilers with and without pulmonary hypertension syndrome (PHS). Liver mitochondria from Control and PHS broilers were incubated with 0, 1, and 5-mM tertiary-butyl hydroperoxide (tBH). Indices of mitochondrial functio...

The National Institutes of Health (NIH) require instruction in the responsible conduct of research (RCR) as a component of any Clinical and Translational Science Award (CTSA). The Educational Materials Group of the NIH CTSA Consortium's Clinical Research Ethics Key Function Committee (CRE-KFC) conducted a survey of the 38 institutions that held CTSA funding as of January 2009 to determine how t...

BACKGROUND Although recent evidence suggests that any prior shoulder surgery may cause inferior shoulder arthroplasty outcomes, there is no consensus on whether previous rotator cuff repair (RCR) is associated with inferior outcomes after reverse total shoulder arthroplasty (RTSA). PURPOSE To retrospectively compare outcomes in patients who underwent RTSA with and without previous RCR. STUD...

PURPOSE To explore the extent to which U.S. research institutions are meeting or exceeding National Institutes of Health and National Science Foundation mandates to provide instruction in responsible conduct of research (RCR). METHOD In summer 2011, the authors sent an e-mail survey to officials responsible for overseeing RCR instructional programs at the 200 top-funded research institutions ...

PURPOSE To examine the effects that existing courses on the responsible conduct of research (RCR) have on ethical decision making by assessing the ethicality of decisions made in response to ethical problems and the underlying processes involved in ethical decision making. These processes included how an individual thinks through ethical problems (i.e., meta-cognitive reasoning strategies) and ...

Porcine circovirus (PCV) has been assumed to replicate its genome via the rolling-circle replication (RCR) mechanism because it encodes a Rep protein that contains several amino acid motifs commonly found in other RCR biological systems. Two proteins, Rep and Rep', are essential for PCV DNA replication in mammalian cells. In this work, replicative intermediates of PCV-infected porcine kidney (P...

Exertional heat stroke (EHS) results in a constellation of systemic inflammatory responses resulting in multiorgan failure and an extremely high mortality. The present study was designed to evaluate the protective effects of salidroside on EHS by improving mitochondrial functions in the rat model. Liver and heart mitochondria were observed by transmission electron microscopy and mitochondrial m...

ÐIn this paper, we introduce a family of scalable interconnection network topologies, named Recursive Cube of Rings (RCR), which are recursively constructed by adding ring edges to a cube. RCRs possess many desirable topological properties in building scalable parallel machines, such as fixed degree, small diameter, wide bisection width, symmetry, fault tolerance, etc. We first examine the topo...

Efforts to advance research integrity in light of concerns about misbehavior in research rely heavily on education in the responsible conduct of research (RCR). However, there is limited evidence for the effectiveness of RCR instruction as a remedy. Assessment is essential in RCR education if the research community wishes to expend the effort of instructors, students, and trainees wisely. This ...
