BACKGROUND We aimed to describe the recent clinical characteristics of Takayasu arteritis (TA). METHODS AND RESULTS We enrolled 106 consecutive TA patients and compared the clinical characteristics of patients with TA onset before 1999 and after 2000, patients with onset at age less than 39 years and more than 40 years, patients with monophasic and relapsing-remitting clinical course, and pat...

Individual RNA aptamers are often used to modulate the function of their target proteins, and multi-valent aptamers have been constructed to enhance their activity. To expand the utility of aptamers in manipulating and controlling biological processes, here we advance a general method for the design and construction of composite aptamers. The resulting molecular constructs resemble proteins in ...

Gas turbine design, development, monitoring and maintenance are widely based on numerical simulations of the steady and transient engine performance. Most of the equations that are solved in the simulation programs involve the thermodynamic properties of the fluid flowing through the engine. These properties depend on temperature, pressure, humidity and fuel dosage. As the solution of chemical ...

OBJECTIVES To investigate the incidence and clinical features of recurrent aphthous stomatitis (RAS) among Israeli Arab adolescents and to determine the HLA typing profile in affected subjects. STUDY DESIGN Cross-sectional study. SETTING Junior high school in the largest Arab town in Israel. PARTICIPANTS Four hundred seventy-seven Israeli Arab junior high school students filled out a ques...

We study the evolution of comparative advantage in a model with two countries and`≥ 2 goods. We show that the stochastically stable set consists of the pattern of production that follows the chain of comparative advantage in a sufficiently large world economy. Also, the chain of comparative advantage has an elegant structure that allows for step-by-step evolution. So convergence towards the equ...

Economic theory has evolved without paying proper attention to behavioral approaches, especially to social, economic, and cognitive psychology. This has recently changed by including behavioral economics courses in many doctoral study programs. Although this new development is most welcome, the typical topics of the behavioral economics courses are not truly behavioral. More specifically, we qu...
