This in vitro study evaluated (1) the dissolution of bovine pulp tissue in solutions consisting of varying NaOCl concentrations and combined with EDTA; and (2) the pH of these solutions before and after the experiment. The independent variables were the concentration and the volume of the solution. Thirty bovine pulps were divided in equal fragments, resulting in 90 fragments of pulp tissue. Ea...

background: to identify and analyze factors that influence the grading and zoning management model of emergency triage as a first step in the improvement of the system. methods: questionnaires were used to extract data from clinical histories of 286 patients who attended the emergency department of binzhou central hospital (binzhou city, shandong province, china) from september to november of 2...

Background: Brachytherapy is the most commonly used conservative treatment for the uveal melanoma. The aim of this study was to evaluate therapeutic results of Ruthenium-106 plaque brachytherapy in the management of localized uveal melanoma cases. Methods: We reviewed retrospectively the clinical records of all patients treated in our department for an uveal melanoma, undergoing Ruthenium-106 p...

We tested the efficacy of preischemic and postischemic systemic treatment with 30,000 units polyethylene glycol-conjugated superoxide dismutase in a reperfusion model of focal cerebral ischemia. Forty-one anesthetized cats underwent 2 hours' occlusion of the left middle cerebral artery and both common carotid arteries followed by 4 hours of reperfusion. Cats were blindly assigned to one of thre...

Safe and appropriate health care, especially in urgent or emergency situations, is the expectation of the public throughout the developed world. Achieving this goal requires appropriate levels of medical and other staff, appropriate training, and sensible working hours. Too often the brunt of such care, especially in out-of-hours situations, is borne by medical residents, who--to make matters w...

We investigated the extent to which the safety performance (i.e., self-reported safety compliance and safety participation) of employees with 2 jobs was predicted by their respective supervisors' transformational leadership behaviors. We compared 2 within-person models: a context-specific model (i.e., transformational leadership experienced by employees in 1 context related to those same employ...

Recent decennial censuses and the American Community Survey (ACS) collect data that permit construction of average hourly wage rates. However, reports concerning usual hours worked during the past year contain errors that create incredible implied wages for part-time workers.

Abstract The purpose of this research was to optimize the drying process and maltodextrin concentration black garlic ( Allium sativum L.) aqueous extract powder using response surface methodology. conditions were based on Box-Behnken design, with 17 kinds variations in temperature (50-70 °C), time (18-30 hours), (5-15 %). moisture content, total flavonoid content antioxidant activity (DPPH, ABT...
