In this task, you are given a abstract of article and corresponding title of an article. Your task is to generate label "yes" if title is right for article, otherwise generate "no".

[Q]: Abstract: Limited neural input results in muscle weakness in neuromuscular disease because of a reduction in the density of muscle innervation, the rate of neuromuscular junction activation or the efficiency of synaptic transmission. We developed a small-molecule fast-skeletal-troponin activator, CK-2017357, as a means to increase muscle strength by amplifying the response of muscle when neural input is otherwise diminished secondary to neuromuscular disease. Binding selectively to the fast-skeletal-troponin complex, CK-2017357 slows the rate of calcium release from troponin C and sensitizes muscle to calcium. As a consequence, the force-calcium relationship of muscle fibers shifts leftwards, as does the force-frequency relationship of a nerve-muscle pair, so that CK-2017357 increases the production of muscle force in situ at sub-maximal nerve stimulation rates. Notably, we show that sensitization of the fast-skeletal-troponin complex to calcium improves muscle force and grip strength immediately after administration of single doses of CK-2017357 in a model of the neuromuscular disease myasthenia gravis. Troponin activation may provide a new therapeutic approach to improve physical activity in diseases where neuromuscular function is compromised..

[Q]: Abstract: Although essentially unknown as a therapeutic concept as recently as a decade ago, it is difficult now to open a cardiology journal, attend a cardiology meeting, or scan a newspaper without being caught up in the excitement generated by the thought that angiogenesis therapy may soon have a major impact on the treatment of patients with atherosclerotic lesions obstructing arteries that supply the myocardium or legs. Potent therapeutic interventions, however, are rarely free of at least the potential for causing harmful effects. Angiogenesis therapy is no exception. Despite this and despite the fact that the only reasonably powered, randomized, double-blind clinical studies to date have failed to demonstrate primary end-point efficacy,1 thoughtful consideration of the serious side effects that might accompany any therapeutic benefit has been largely missing from scientific communications. For the lay media, a switch from this unbounded enthusiasm to profound skepticism occurred recently after a report of the tragic death of a young man caused by injection of large amounts of an adenoviral vector into the hepatic artery (unrelated to angiogenesis therapy).2 For the scientific community, however, there has been a general lack of in-depth discussion of the potential dangers inherent in angiogenesis interventions. Such a discussion is appropriate not only because of the event cited above but also because considerable mechanistic data are available that actually permit us to identify specific side effects that we might anticipate as potential complications of angiogenesis therapy. The following therefore is a discussion of potential complications based predominantly on our knowledge of the underlying biological activities of 2 of the most potent angiogenic cytokines, vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF). Angiogenic agents are thought to have the potential to induce neovascularization in many different tissues. This becomes important in that under clinical circumstances it .

[Q]: Abstract: Oxysterols are oxygenated cholesterol derivates that are emerging as a physiologically important group of molecules. Although they regulate a range of cellular processes, only few oxysterol-binding effector proteins have been identified, and the knowledge of their binding mode is limited. Recently, the family of G protein-coupled seven transmembrane-spanning receptors (7TM receptors) was added to this group. Specifically, the Epstein-Barr virus-induced gene 2 (EBI2 or GPR183) was shown to be activated by several oxysterols, most potently by 7,25-dihydroxycholesterol (7,25-OHC). Nothing is known about the binding mode, however. Using mutational analysis, we identify here four key residues for 7,25-OHC binding: Arg-87 in TM-II (position II:20/2.60), Tyr-112 and Tyr-116 (positions III:09/3.33 and III:13/3.37) in TM-III, and Tyr-260 in TM-VI (position VI:16/6.51). Substituting these residues with Ala and/or Phe results in a severe decrease in agonist binding and receptor activation. Docking simulations suggest that Tyr-116 interacts with the 3-OH group in the agonist, Tyr-260 with the 7-OH group, and Arg-87, either directly or indirectly, with the 25-OH group, although nearby residues likely also contribute. In addition, Tyr-112 is involved in 7,25-OHC binding but via hydrophobic interactions. Finally, we show that II:20/2.60 constitutes an important residue for ligand binding in receptors carrying a positively charged residue at this position. This group is dominated by lipid- and nucleotide-activated receptors, here exemplified by the CysLTs, P2Y12, and P2Y14. In conclusion, we present the first molecular characterization of oxysterol binding to a 7TM receptor and identify position II:20/2.60 as a generally important residue for ligand binding in certain 7TM receptors..
