A multistep two-component signaling system is established as a key element of cytokinin signaling in Arabidopsis. Here, we provide evidence for a function of the two-component signaling system in cold stress response in Arabidopsis. Cold significantly induced the expression of a subset of A-type ARR genes and of GUS in Pro(ARR7):GUS transgenic Arabidopsis.(More)
We investigated the effects of different concentrations of auxin and auxin/cytokinin combinations, inoculum sizes and Murashige and Skoog (MS) medium dilutions on biomass and accumulation of total phenols and flavonoids in adventitious roots of Hypericum perforatum. The optimized conditions for the shake flask culture growth and secondary metabolites(More)
Plant cell and organ cultures have emerged as potential sources of secondary metabolites, which are used as pharmaceuticals, agrochemicals, flavors, fragrances, coloring agents, biopesticides, and food additives. In recent years, various strategies have been developed to assess biomass accumulation and synthesis of secondary compounds in cultures. Biomass(More)
The overactivation of macrophages causes abnormal cell death and chronic inflammatory diseases. Therefore, the modulation of macrophage-mediated cytotoxicity is expected to become a new therapeutic strategy for various inflammatory diseases. In this study, three types of short chain fatty acids (sodium butyrate (NaB), sodium phenylbutyrate (NaPB), sodium(More)
The possible risk of colonic perforation during endoscopic submucosal dissection (ESD) for colorectal tumors is a barrier to wide application. This retrospective study was performed to evaluate the risk and the predictive factors for perforation during ESD procedure. Between October 2006 and November 2010, a total of 499 consecutive patients (mean age 60.0(More)
TWIK-related K(+) channel (TREK)-2 is thought to contribute to setting the resting membrane potential and to tuning action potential properties. In the present study, the effects of divalent metal ions (Ba(2+), Co(2+), Ni(2+), Pb(2+), and Zn(2+)) were examined on TREK-2 expressed in Xenopus oocytes using the two-electrode voltage clamping technique. Pb(2+)(More)
As there is growth in the need of applications such as video conferencing and interactive chatting, secure group communication is an important research area. Security in these applications is necessary to provide services like privacy, data-integrity, and non-repudiation to group members. A naive way to achieve security in such groups is to have a secret(More)
The mutation or overexpression of alpha-synuclein protein plays a pivotal role in the pathogenesis of Parkinson's disease. In our preliminary experiments, we found that alpha-synuclein induced the expression of matrix metalloproteinases (MMPs) (MMP-1, -3, -8, and -9) in rat primary cultured microglia. Thus, the current study was undertaken to determine the(More)
We evaluated the role of FDG-PET/CT in patients with metastatic gastric adenocarcinoma before palliative chemotherapy to predict prognosis and chemotherapeutic response. The study included 35 consecutive newly diagnosed patients with metastatic gastric adenocarcinoma who underwent FDG-PET/CT before palliative chemotherapy. Maximum standardized uptake value(More)
In an attempt to improve growth and secondary metabolite production, and to understand the possible mechanism involved in relation to the changes in physiology and activities of antioxidant enzymes, we cultured Morinda citrifolia adventitious roots in different strength (0.25, 0.50, 0.75, 1.0, 1.5 and 2.0) of Murashige and Skoog (MS) medium supplemented(More)
