Aims. The existence of dark matter can be proved in an astrophysical context by the discovery of a system in which the observed baryons and the inferred dark matter are spatially segregated, such as the bullet cluster (1E0657-558). The full descriptions of the dark matter halo and X-ray gas substructure motions are necessary to forecast the location of the dark halo from X-ray maps, which can b...
BACKGROUND Prehospital spinal immobilization criteria are useful in identifying those at risk for spinal fractures, while reducing the number of patients unnecessarily immobilized. The use of immobilization criteria, without regard to mechanism of injury, has been shown to accomplish this task. AIMS The study's purpose is to examine efficacy of a prehospital spinal clearance guideline and tri...
A method for the determination of total reducing capacity (TRC) based on the reduction of Cu(II) to Cu(I) by antioxidants in a buffered solution (pH 7.0) containing 4,4'-dicarboxy-2,2'-biquinoline acid (BCA) was developed. Absorbance values at 558 nm characteristic of the Cu(I)/BCA complexes formed were used to determine the TRC of aqueous extracts of twelve Brazilian plants. The TRC values obt...
MYCN is a major driver of neuroblastoma tumorigenesis and MYCN amplification is the worst prognostic indicator of aggressive NB. To identify potentially therapeutic tumor suppressor microRNAs for aggressive NB, we utilized a conditional MYCN system to simulate MYCN-amplified and nonamplified tumor types and performed a genome-wide search for MYCN target microRNA promoters differentially repress...

Objective: This study aims to explore the incidence and risk factors of nosocomial infections (NIs) in the intensive care unit (ICU) in China. Methods: Between January 2011 and December 2013, a total of 1718 patients with a mean age of 59.02 ± 20.71 years in ICU were included. Clinical data of these patients, including gender, age, length of stay, the overall rate of patients with NIs, the dist...
