To investigate effect 6 months safe weight loss program on anthropometric measurements and biological and metabolic profiles in obese patients. 35 obese patients were enrolled in the present study： 20 female, 15 male. Participants underwent a comprehensive series of biochemical, anthropometrical, physical, and nutritional prior to treatment- at baseline and after the six-month of the obesity treatment program. 6 months weight loss program. Diet plan intervention in small groups. In-person training and individual diet plan intervention. There is significant reduction in weight and high improvement in laboratory parameters.

It demonstrates that such interactions with the rest of the world are trying to establish some semiotic functions, in an effort behaviorally to overcome the children＇s disability. The author＇s aim is to analyze such a paradoxical way of communicational interaction of such a subject vs. a given objectively perceivable reality, thus attempting to reveal paradoxical social contexts. The focus is on interpersonal communication abilities and/or disabilities, thus allowing semiotically distinguishable units as an object of analysis. The problem of mental disorders, such as ASD, requires a multi-dimensional approach--e.g., biological, medical, and other related fields. In conclusion, by applying a semiotic analysis, it becomes necessary to communicate with such children in a whole new way which, by processes of transformation, can bring about a state of awareness of a paradoxical and/or abnormal phenomenon.展开更多

Hereby for such equations, via the Hirota method and syrnbolic computation, analytic soliton solutions in the bright-dark and dark-dark forms are obtained. Based on the choice of photorefrac- rive polymer parameter and incident-optical-beam parameter, the bright-dark and dark-dark solitons as well as their interaction can occur in the polymer when the total intensity is much lower than the background illumination, and our analysis indicates that the incident light with different polarization directions influence little on the soliton propagation. ~, representing the soliton intensity far away from the soliton center, determines the appearance of bright or dark soliton under the background illumination. Through the graphic and asymptotic analysis on the two-soliton solutions along with the different ~, we find that there exist the elastic and inelastic interactions between the bright-dark solitons, while the interactions between the dark-dark solitons are always elastic.展开更多
