objective we have previously shown that rose bengal (rb) alone, not as a photosensitiser, could induce apoptotic- and non-apoptotic cell death in different melanoma cell lines. to clarify rb-induced toxicity mechanisms, role of caspases and reactive oxygen specious (ros) were studied in melanoma cells. material and methods human melanoma cell lines, me 4405 and sk-mel-28 were cultured in dmem m...

conclusions according to the present study, rose water noticeably reduces the anxiety of hemodialysis patients. therefore, inhalation of rose water can improve the patient’s emotional and spiritual condition during hemodialysis treatment. results mean scores of state and trait anxiety in the experimental group before intervention were 47/47 ± 7/6 and 49/56 ± 13/8, respectively; those after week...

The National Forest City (NFC) project is an important measure to promote the urban environment in China, but its environmental performances have not been fully evaluated yet. This paper uses difference-in-differences (DID) evaluate smog pollution controlling effects and mechanisms of NFC based on panel data 283 cities China from 2000 2018. study found following: (1) significantly reduced by 3....

the effects of sodium chloride (nacl) salinity (control; canal water with 0.4 ds m-1), 2.5 dsm-1, 5.0 ds m-1, 7.5 ds m-1 and 10.0 ds m-1, respectively) developed after 6 weeks of pruning (beginning of study) on plant growth, flowering and quality of three cut rose (rosa hybrida l.) cultivars viz. ‘kardinal’, ‘angelique’ and ‘gold medal’ were studied to achieve better management, quality product...

nanosilver of nanometer-sized silver (ag+) particles (2-5 nm diam) are used in various applications as an anti-microbial. boric acid (h3bo3) is water soluble (ph=7). boric acid is ethylene synthese inhibitor and reduce ethylene production through reducing the acc synthase and acc oxidase delays senescence of flower. in this study of different concentrations of boric acid and nano-silver was eva...

We report the results of a study on students’ interest in physics at the end of their compulsory schooling in Israel carried out in the framework of the ROSE Project. Factors studied were their opinions about science classes, their out-of-school experiences in physics, and their attitudes toward science and technology. Students’ overall interest in physics was “neutral” (neither positive nor ne...

In this paper, we report the first observation of metal-enhanced fluorescence emission of fluorophores from paper substrates. The fluorescence intensity is z5and z9-fold brighter from Rose Bengal (RB) and Pt(II) octaethylporphine (PtOEP), respectively, on silver colloid-deposited paper as compared to uncoated paper. In addition, a reduced lifetime of RB near to silver particles (0.77 ns) was ob...

The eigenvalues of the potentials V1(r) = A1 r + A2 r2 + A3 r3 + A4 r4 and V2(r) = B1r + B2 r2 + B3 r4 + B4 r6 and of the special cases of these potentials such as Kratzer and Goldman– Krivchenkov potentials, are obtained in N -dimensional space. The explicit dependence of these potentials in higher-dimensional space is discussed, which has not been previously covered. PACS numbers: 03.65.Fd, 0...
