Mutualistic symbioses between scleractinian corals and endosymbiotic dinoflagellates (Symbiodinium spp.) are the foundation of coral reef ecosystems. For many coral-algal symbioses, prolonged episodes of thermal stress damage the symbiont's photosynthetic capability, resulting in its expulsion from the host. Despite the link between photosynthetic competency and symbiont expulsion, little is kn...
The quadruplex structures of the human telomere sequences AG3(T2AG3)3 I and (T2AG3)4 II were investigated in the presence of Na+ and K+ ions, through the cross-linking of adenines and guanines by the cis- and trans-[Pt(NH3)2(H2O)2](NO3)2 complexes 1 and 2. The bases involved in chelation of the cis- and trans-Pt(NH3)2 moieties were identified by chemical and 3'-exonuclease digestions of the pro...
Tec kinase, a prototypical member of the Tec tyrosine kinases family, was shown to mainly govern lymphocyte proliferation. In the present study, we investigated the role of Tec kinase in acute inflammatory response in lipopolysaccharide (LPS) challenge. First, we demonstrate that Tec kinase activity was observed in RAW264.7 macrophages exposed to LPS. Tec and phosphorylated Tec expression were ...
PURPOSE Aberrantly upregulated expression of selected members of annexin, a group of calcium- and membrane-binding proteins, have been found to be associated with metastasis, poor prognosis, and other clinical characteristics in colorectal cancer (CRC), the third most diagnosed cancer. However, ANXA13 (encoding protein annexin A13), the original founder gene of the annexin A family, has not bee...
Polymyositis mediated by gamma/delta T cells is a unique disease in which autoaggressive T lymphocytes surround, invade, and destroy muscle fibers. Histochemically, the vast majority of muscle-infiltrating T cells in a patient with polymyositis were reactive with a pan-gamma/delta T cell receptor (TCR)-specific monoclonal antibody (TCR-delta 1+), but unlike > 90% of peripheral blood gamma/delta...
Peut-on reconstruire sans la trahir pensée économique de Marx à partir théorie néoclassique ? C’est question laquelle a tenté répondre John Roemer. Il fut l’un des principaux contributeurs du marxisme analytique – plus précisément choix rationnel –, principalement au cours années 1980. L’objectif fondateur ce courant été parvenir conclusions proches celles en utilisant outils méthodologiques di...
It is an increased interest in the therapeutic potential of Cannabis sativa L. (marijuana) for treatment of multiple sclerosis and HIV neuropathy. Because of limitation in cultivation of this plant, an efficient hairy root induction system for Cannabis sativa L. was developed in the present study. Agrobacterium rhizogenes mediated transformation performed by two different co-cultivation mediums...
سابقه و هدف: امروزه استفاده از رنگدانههای آلی تولید شده توسط میکروارگانیسمها با توجه به ماهیت و ایمنی آنها در حال افزایش است. این رنگدانهها در طبیعت و خواص خود متفاوت هستند. هدف از مطالعه حاضر، استخراج رنگدانههای تولید شده در سرما توسط باکتریهای سرمادوست است. روش بررسی: 10 نمونه خاک از مناطق مختلف شهر طرقبه جمعآوری و کشت داده شدند. 10 روز بعد، تعداد 14 کلنی باکتریایی که مولد رنگدانه بودند...
