BACKGROUND Intravenous (i.v.) thrombolysis within 4.5 h of symptom onset has proven efficacy in acute ischemic stroke treatment, although half of all outcomes are unfavorable. The recently published DRAGON score aims to predict the 3-month outcome in stroke patients who have received i.v. alteplase. The purpose of this study was an external validation of the results of the DRAGON score in a Spa...

energy drink consumption by athletes has become increasingly popular. the aim of this study was to determine the effect of phantom and dragon energy drinks on female athlete students. for this purpose, twelve female athlete students of tehran university (age 22+0.63 years, height 162.1+5.8 cm, weight 56.91+6.79 kg) volunteered to participate in this study and performed three sessions of a bruce...

ab initio calculations at hf/6-31g* level of theory for geometry optimization and mp2/6-31g*//hf/6-31g*for total energy calculation are reported for z-cyclooctene (1). the most favorable conformation of 1 is theunsymmetric boat-chair (1-bc) geometry. potential energy profiles for two different boat-chair/boat-chairinterconversion processes were calculated. the process via a chair transition sta...

To verify the applicability of a new approach based on the strength curves (SCs) methodology in late arm impairment in breast cancer (BC) survivors and to evaluate the effects of dragon boat (DB) activity on the late regaining of the muscle strength, upper limb impairment, and quality of life in patients undergoing surgery for BC.Retrospective observational study on 64 subjects (54.5 ± 9.7 year...

The Twin Dragon and Rauzy fractals are intersected with the real axis. In the Twin Dragon case, unexpectedly from its fractal nature, the intersection is an interval characterized by a finite automaton. For the case of the Rauzy fractal, it is proved that the intersection has infinitely many components.

Grid-based path finding is required in many games to move agents. We present an algorithm called DBA* that uses a database of pre-computed paths to reduce the time to solve search problems. When evaluated using benchmark maps from Dragon Age, DBA* requires less time for search and produces less suboptimal paths than the PRA* implementation used in Dragon Age.

Objective: To provide external validation of the DRAGON Score for predicting outcome after intravenous thrombolysis Methods: A retrospective chart analysis was performed in stroke patients receiving IV-tPA within the 4.5 hour time window from January 2009 to September 2013. A total of 149 patients were included in the analysis. DRAGON scores were calculated for each patient and compared to modi...

The results of MNDO, AM1 and PM3 semi-empirical calculations and HF/6-31G*, MP/6-31G*, MP2/6-311+G**, and B3LYP/6-311G** and QCISD/6-31G* ab initio methods for angle strain and conjugation effects in twist-boat, boat, and half-chair geometries of (Z,Z,Z)-cycloocta-1,3,5-triene indicate that all methods, except PM3, predict wrong ordering of the conformations.

Background. Physical activity initiation and maintenance are particular challenges in the postmastectomy recovery and in particular Dragon Boat racing seems to be a useful sport activity. The aim of this study was to evaluate the role of focal muscle vibration as a proprioceptive input to improve upper limb functioning in a group of "paddlers" patients. Methods. A group of paddlers has been eva...
