Duchenne muscular dystrophy (DMD) is a genetic disorder linked to chromosome Xp21, due to absence of dystrophin production. It is clinically characterized by progressive muscle weakness, fatigue, and development of joint contractures that compromise general motor functionality, mainly the gait. Objective: To characterize the motor function and decrease gait in children with DMD using the Portuguese version of the Motor Function Measure scale (MFM-P). Methods: A review of medical records including chronological age and scores from MFM-P of children with a DMD who attended at the Neuromuscular Diseases Clinic at Campinas State University (UNICAMP), Brazil was performed in this study. A total of 36 medical records of male patients with confirmed clinical diagnosis of DMD, ambulatory or not, regardless of age; excluding those with other associated diseases or other types of muscular dystrophies were selected. Data were analyzed using Kolmogorov-Smirnov and Spearman correlation statistical tests. Results: Analysis of all data collected showed that 75% of our sample had D1 scores lower than 41.02%. There was a linear relationship between the scores of D2 and D3, but no association between D2 and D1 scores was noted. D1 score was between 40% and 80% in those patients presenting D2 scores between 80% and 100%. In all cases patients with low total score presented a greater risk for loss of gait and their functionality. Conclusion: The standing posture and the postural transfers were the worst activities observed in children with DMD, with positive correlation between proximal and distal motor function. Even with high scores according MFM-P in proximal function, the children showed strong predictors for loss of gait.

Does Immigration Promote the Investment of the Monopolistic Firm?

In the present paper, we examine the effect of increasing uncertainty of immigrants’ growth on the optimal timing of investment of a firm that has a monopolistic power over the labor market. It is revealed that when the uncertainty of immigrants’ growth is more than a threshold level, increasing uncertainty of immigrants’ growth accelerates the optimal timing of firms’ investment and enhances the economic growth, even if the uncertainty of immigrants’ growth is formulated by the geometric Brownian motion, which is in sharp contrast to the standard result that an increase in the uncertainty postpones the optimal timing. With an increase in the immigrants over the past ten years, workforces in the host countries have been growing significantly to the extent that the immigrants represent 70% of the increase in the workforce in Europe, and 47% in the United States as OECD indicates. In the present paper, we attempted to investigate the effect of increased uncertainty caused by the growi...

Education Policy Implementation: A Mechanism for Enhancing Primary Education Development in Zanzibar

Education is one of the fundamental rights of individuals; therefore, the government of a country needs to develop and strengthen educational policy and quality as well as to ensure that everyone has equal access to basic education. The improvement of access and quality of education in the world is becoming as an essential factor in development, whereas the basic education (primary school), is acknowledged as a foundation of the higher educational development for every country. To fulfill this goal, governments introduce several policies and procedures; however, it requires some reforms and participation from the politician, policymakers, and other stakeholders to re-examine educational policy so that it can lead to multiplication and betterment of the reforms. Educational reforms actually focus on accountability. A positive educational development and reform is very challenging and needs more effort and strategy on how to use and utilize the resources effectively as such it can achie...

Electron Spin and Proton Spin in the Hydrogen and Hydrogen-Like Atomic Systems

Read full paper at: http://www.scirp.org/journal/PaperInformation.aspx?PaperID=52202#.VIj7tMnQrzE Author(s) Stanisław Olszewski * Affiliation(s) Institute of Physical Chemistry, Polish Academy of Sciences, Warsaw, Poland . ABSTRACT The mechanical angular momentum and magnetic moment of the electron and proton spin have been calculated semiclassically with the aid of the uncertainty principle for energy and time. The spin effects of both kinds of the elementary particles can be expressed in terms of similar formulae. The quantization of the spin motion has been done on the basis of the old quantum theory. It gives a quantum number n = 1/2 as the index of the spin state acceptable for both the electron and proton ...
