  • Phytochromes are red and far-red light absorbing photoreceptors for photomorphogenesis in plants. The red/far wavelength reversible biliproteins are made up of two structural domains. The light-perceiving function of the photoreceptor resides in the N-terminal domain, whereas the signal transducing regulatory function is located within the C-terminal domain. The characteristic role of the phytochromes as phtosensory molecular switches is derived from the phototransformation between two distinct spectral forms, the red light absorbing Pr and the far-red light absorbing Pfr forms. The photoinduced Pr Pfr phototransformation accompanies subtle conformational changes throughout the phytochrome molecule. The conformational signals are subsequently transmitted to the C-terminal domain through various inter-domain crosstalks and induce the interaction of the activated C-terminal domain with phytochrome interacting factors. Thus the inter-domain crosstalks play critical roles in the photoactivation of the phytochromes. Posttranslational modifications, such as the phosphorylation of Ser-598, are also involved in this process through conformational changes and by modulating inter-domain signaling.

  • Phenanthrene-induced changes in blood organic components. transaminase and ALP activities of Paralichthys oIivaceus were investigaled. The aim of this study was to obtain a holistic view of the toxic responses, and compensations of fish exposed to waterborne phenanthrene. Fish were exposed to 0, 0.5, 1, 2$\mu$M of phenanthrene for 4 weeks. The most noticeable changes were concentration-dependent increase in levels of blood GOT and GPT activities. At concentrations 1.0 and 2.0 $\mu$M of phenanthrene GOT, GPT and ALP enzyme activities in plasma were increased. Plasma albumin concentration was stable in phenanthrene-exposed fish, however, plasma total protein level was reduced significantly at the 4-week sampling points (2.0$\mu$M). Plasma glucose levels were found to be increased significantly over the cootrol throughout duration of the experiment with phenanthrene. Overall the results suggest that phenanthrene has the potential to alter some physiological functions in olive flounder.

  • Purpose: This study is a qualitative research to identify new nurses' adaptation experience to sleep changes. Method: Grounded theory methodology was utilized. Participants were 10 new nurses from one university hospital. The information was collected and analyzed using the grounded theory of Corbin and Strauss'(2008). Results: Through constant comparative analysis, central phenomenon was identified as 'Shaky daily life due to the sleep change'. A core category emerged as 'In the shaky daily life, go grab my position', Causal conditions were 'Heaviness in shift work', 'Not released after getting off work', and 'Body and mind are exhausted'. Context were 'An environment that does not tolerate mistakes' and 'Clogged breathing due to worries'. Intervening factors were 'Support of colleagues', 'Recovery volition in restoration of altered relationships due to sleep'. Action/Interaction Strategies were 'To strive for a good sleep', 'Require a reasonable duty schedule' and 'Find a breakthrough'. Consequences were 'Become the master of shaky daily life' and 'Accepting the life of a nurse'. Conclusion: New nurses experience sleep patterns changes from the hospital shift system. but throughout the process of adaptation, came to accept sleep disorder as part of the life of a nurse.
