The Japanese Psycho-Oncology Society and the Japanese Association of Supportive Care in Cancer developed evidence-based clinical practice guidelines for the care of psychologically distressed bereaved families who have lost members to physical illness including cancer. The guideline development group formulated two clinical questions. A systematic literature review was conducted. The level of evidence and the strength of the recommendations were graded and recommendation statements validated using the modified Delphi method. The recommendations were as follows: non-pharmacological interventions were indicated for serious psychological distress (depression and grief); antidepressants were indicated for depression; however, psychotropic medications including antidepressants were not recommended for ‘complicated’ grief. These guidelines will facilitate the provision of appropriate care to distressed bereaved family members and highlight areas where further research is needed.
Enterobacterial plasmid genes mucAB, which possess error-prone repair activity, were cloned and sequenced independently of a sequence previously determined (K.L. Perry, S.J. Elledge, B.B. Mitchell, L. Marsh, and G.C. Walker, Proc. Natl. Acad. Sci. USA 82:4331-4335, 1985). The survival- and mutation-enhancing activities of mucAB ligated to the MLSr promoter of a Bacillus subtilis plasmid in the shuttle vector pTE22R were expressed in B. subtilis as well as in Escherichia coli after mutagenic treatment. mucAB fragments with 5' deletions of various lengths up to the base sequence encoding Ala-26-Gly-27, the putative RecA-mediated cleavage site of the MucA protein, showed mutation-enhancing activity for noninducible lexA3 E. coli when ligated to the MLSr promoter in frame. This activity was lost by extending the deletion downstream. The formations of MucA and MucB proteins in B. subtilis and E. coli were demonstrated by Western blot (immunoblot) analysis. MucA cleavage in Rec+ B. subtilis was observed only after treatment with an alkylating agent and was not observed in RecA- and RecE- strains, whereas in E. coli cleavage was observed in Rec+ cells after treatment with either mitomycin C or an alkylating agent but was not detected in RecA- cells. Common activity of B. subtilis Rec and E. coli RecA in the induction of mutants is suggested.
Polarized Raman scattering measurements were made of a single crystal of a-pseudouridine by the use of a Raman microscope with 488. 0 nm exciting radiation from an argon ion laser. The crystal belongs to space group P2 1 (monoclinic), and Raman scattering intensities, corresponding to the aºaº, bb, cc, aºb and bc components of the crystalline Raman tensor, were determined for each prominent Raman band. Here the aº-axis was deÐned as an axis perpendicular to the c-axis in the ac plane. From the experimental results, the shapes and orientations of the Raman scattering tensors were derived for 12 base vibrations in pseudouridine. By comparing these tensors with those determined previously for uracil and thymine vibrations, the polarizability oscillations caused by normal vibrations localized in the pyrimidine base are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
