Background Ketamine is an antagonist receptor of N-methyl-D-aspartate (NMDA), and phencyclidine derivate sedative agent. Thus the aim of this study was to evaluate the effect of intravenous (IV) and intramuscular (IM) injection of Ketamine for sedation procedure of children. Materials and Methods In this randomized clinical trial the patients, 1-6 year-old children referred to Emergency Departm...

A significant amount of contribution to pragmatics research comes from cross-cultural and developmental pragmatic studies with L2 learners in focus; however, despite broad interest in such analyses, the role of lecturers has been relatively ignored. As the lectures’ perceptions/opinions of L2 learners’ e-mail requests are important, L2 learners must become familiar with their lecturers’...

  Abstract   Background: The tibial diaphyseal fractures are the most common type of long   bone fractures encountered by most orthopedic surgeons. In accordance with descriptive indices of tibia fractures on the basis of their location in the bone, distal tibia   fractures have the second incidence of all tibia fractures after the middle tibia fractures.   The purpose of the study was to asses...

background and aims. maintenance of interdental soft tissue and the need for aesthetics are increasingly recognized as important criteria for implant success. the aim of this prospective clinical study was to compare the peri-implant and prosthetic conditions for single-tooth implants, placed according to the immediate (im) and the delayed (de) placement protocols at 18-month follow-up examinat...

background: chronic fatigue syndrome (cfs) is a complex condition involving severe fatigue and disabling musculoskeletal and cognitive symptoms. we reported that 6, 12 and 24 months following infectious mononucleosis (im), 13%, 7% and 4% of adolescents, respectively, met criteria for cfs. whether endocrinologic or immunologic dysfunction accompanies cfs is unclear. objectives: to determine if s...

CONTEXT Shortfalls in the US physician workforce are anticipated as the population ages and medical students' interest in careers in internal medicine (IM) has declined (particularly general IM, the primary specialty serving older adults). The factors influencing current students' career choices regarding IM are unclear. OBJECTIVES To describe medical students' career decision making regardin...

In this paper, we apply the FM methodology to the cross-section of Romanian-listed common stocks and investigate the explanatory power of market beta on the cross-section of commons stock returns from Bucharest Stock Exchange. Various assumptions are empirically tested, such us linearity, market efficiency, the “no systematic effect of non-beta risk” hypothesis or the positive expected risk-ret...

This paper evaluates the specification errors of several empirical asset pricing models that have been developed as potential improvements on the CAPM. We use the methodology of Hansen and Jagannathan (J. Finance 51 (1997) 3), and the test assets are the 25 Fama-French (J. Financial Econom. 52 (1997) 557) equity portfolios sorted on size and book-to-market ratio, and the Treasury bill. We allow...

The T:G mismatched base pair is associated with many genetic mutations. Understanding its biological consequences may be aided by studying the structural perturbation of DNA caused by a T:G base pair and by specific probing of the mismatch using small molecular ligands. We have shown previously that AR-1-144, a tri-imidazole (Im-Im-Im) minor groove binder, recognizes the sequence CCGG. NMR stru...
