You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
In this task, you are given an abstract of article. Your task is to generate label "True" if abstract is structured, otherwise generate "False". A structured abstract is composed of a topic sentence (or key sentence), relevant supporting sentences, and a closing (or transition) sentence. This structure is key to keeping your abstract focused on the main idea and creating a clear and concise image.

RanBP type proteins have been reported to increase the catalytic efficiency of the RanGAP-mediated GTPase reaction on Ran. Since the structure of the Ran-RanBP1-RanGAP complex showed RanBP1 to be located away from the active site, we reinvestigated the reaction using fluorescence spectroscopy under pre-steady-state conditions. We can show that RanBP1 indeed does not influence the rate-limiting step of the reaction, which is the cleavage of GTP and/or the release of product P(i). It does, however, influence the dynamics of the Ran-RanGAP interaction, its most dramatic effect being the 20-fold stimulation of the already very fast association reaction such that it is under diffusion control (4.5 x 10(8) M(-1) s(-1)). Having established a valuable kinetic system for the interaction analysis, we also found, in contrast to previous findings, that the highly conserved acidic C-terminal end of RanGAP is not required for the switch-off reaction. Rather, genetic experiments in Saccharomyces cerevisiae demonstrate a profound effect of the acidic tail on microtubule organization during mitosis. We propose that the acidic tail of RanGAP is required for a process during mitosis.
Solution: False
Why? Output is appropriate for the given abstract because it is not structured.

New input: Two hundred patients who were taking daily symptomatic or immediate relief medications, often in excessive quantities, yet suffering from daily or near daily severe headaches were studied. One hundred and sixteen (58%) of them were also taking concomitant prophylactic medications and they were ineffective. Low tyramine, low caffeine dietary instructions and biofeedback training were given to all patients. The effect of continuing symptomatic medications, discontinuing symptomatic medications, and adding or changing prophylactic medications were studied in the various treatment groups. It is concluded that; 1.) Daily use of symptomatic or immediate relief medications result in chronic daily headache. 2.) Discontinuing daily symptomatic medications itself result in improvement of headache. 3.) Concomitant use of symptomatic medications nullifies the effect of prophylactic medications. 4.) Discontinuing daily symptomatic medications enhances the beneficial effect of prophylactic medications.
Solution:
False
