In this Brief Report, we consider parametrically driven bright solitons in the vicinity of the anticontinuum limit. We illustrate the mechanism through which these solitons become unstable due to the collision of the phase mode with the continuous spectrum, or eigenvalues bifurcating thereof. We show how this mechanism typically leads to complete destruction of the bright solitary wave.
Efficacy and mechanism of action of turmeric supplements in the treatment of experimental arthritis.
OBJECTIVE Scientific evidence is lacking for the antiarthritic efficacy of turmeric dietary supplements that are being promoted for arthritis treatment. Therefore, we undertook studies to determine the antiarthritic efficacy and mechanism of action of a well-characterized turmeric extract using an animal model of rheumatoid arthritis (RA). METHODS The composition of commercial turmeric dietar...
Ume6p represses early meiotic gene transcription in Saccharomyces cerevisiae by recruiting the Rpd3p histone deacetylase and chromatin-remodeling proteins. Ume6p repression is relieved in a two-step destruction process mediated by the anaphase-promoting complex/cyclosome (APC/C) ubiquitin ligase. The first step induces partial Ume6p degradation when vegetative cells shift from glucose- to aceta...
Murine ovarian tumors produced by polycyclic aromatic hydrocarbons like benzo(a)pyrene (BP) require small oocyte destruction. Small oocyte destruction was evaluated in C57BL/6N (B6), DBA/2N (D2), and C57BL/6J X DBA/ 2JF1 (B6D2F1) mice following intraovarian injection with BP, (+)-( 7R ,8S)-oxide, (-)-( 7R , 8R )-dihydrodiol [(-)-DHD], or (+)-( 7R ,8S)-diol-(9S, 10R )-epoxide-2 [(+)- DE2 ] at do...
We study the process of destruction synchronous oscillations in a model two interacting microbubble contrast agents exposed to an external ultrasound field. Completely this are possible case identical bubbles, when governing system equations possess symmetry leading existence synchronization manifold. Such can be destructed without breaking corresponding dynamical system. Here we describe pheno...
Periodontitis is an inflammatory mechanism causing step by destruction of the periodontal tissues and alveolar bone. Periodontal treatment intended to restore damaged disease. Various procedures have been introduced lower destruction; statins are being one among them. They cholesterol-reducing drugs which shown promote bone formation proven be effective in therapy. However, numerous actions, wi...
