    We search for CPCP violation by measuring a TT-odd asymmetry in the Cabibbo-suppressed D+→K+KS0π+π−D^{+}\rightarrow K^{+}K^{0}_{S}\pi^{+}\pi^{-} decay, and in the Cabibbo-favored Ds+→K+KS0π+π−D^{+}_{s}\rightarrow K^{+}K^{0}_{S}\pi^{+}\pi^{-} and D+→K+K−KS0π+D^{+}\rightarrow K^{+}K^{-}K^{0}_{S}\pi^{+} decays. We use 980 fb−1{\rm fb}^{-1} of data collected by the Belle detector running at the KEKB asymmetric-energy e+e−e^{+}e^{-} collider. The C ⁣PC\!P-violating TT-odd parameter aCPT-odd{a}^{T\text{-}\rm{odd}}_{CP} is measured to be aCPT-odd(D+→K+KS0π+π−)=(0.34±0.87±0.32)%,{a}^{T\text{-}\rm{odd}}_{CP}(D^{+}\rightarrow K^{+}K^{0}_{S}\pi^{+}\pi^{-})=(0.34\pm0.87\pm0.32)\%, aCPT-odd(Ds+→K+KS0π+π−)=(−0.46±0.63±0.38)%,{a}^{T\text{-}\rm{odd}}_{CP}(D^{+}_{s}\rightarrow K^{+}K^{0}_{S}\pi^{+}\pi^{-})=(-0.46\pm0.63\pm0.38)\%, and aCPT-odd(D+→K+K−KS0π+)=(−3.34±2.66±0.35)%,{a}^{T\text{-}\rm{odd}}_{CP}(D^{+}\rightarrow K^{+}K^{-}K^{0}_{S}\pi^{+})=(-3.34\pm2.66\pm0.35)\%, where the first uncertainty is statistical and the second is systematic. We also report the first observation of the Cabibbo-suppressed decay Ds+→K+K−KS0π+D^{+}_{s}\rightarrow K^{+}K^{-}K^{0}_{S}\pi^{+}. The branching fraction is measured relative to that of the analogous Cabibbo-favored decay : B(Ds+→K+K−KS0π+)/B(Ds+→K+KS0π+π−)=(1.36±0.15±0.04)%B(D^{+}_{s}\rightarrow K^{+}K^{-}K^{0}_{S}\pi^{+}) / B(D^{+}_{s}\rightarrow K^{+}K^{0}_{S}\pi^{+}\pi^{-}) = (1.36\pm 0.15\pm 0.04)\%

    Abstract We perform the first search for CP violation in D s + → K S 0 K − π + π + D(s)+→KS0K−π+π+ {D}_{(s)}^{+}\to {K}_S^0{K}^{-}{\pi}^{+}{\pi}^{+} decays. We use a combined data set from the Belle and Belle II experiments, which study e + e − collisions at center-of-mass energies at or near the Υ(4S) resonance. We use 980 fb −1 of data from Belle and 428 fb −1 of data from Belle II. We measure six CP-violating asymmetries that are based on triple products and quadruple products of the momenta of final-state particles, and also the particles’ helicity angles. We obtain a precision at the level of 0.5% for D + → K S 0 K − π + π + D+→KS0K−π+π+ {D}^{+}\to {K}_S^0{K}^{-}{\pi}^{+}{\pi}^{+} decays, and better than 0.3% for D s + → K S 0 K − π + π + Ds+→KS0K−π+π+ {D}_s^{+}\to {K}_S^0{K}^{-}{\pi}^{+}{\pi}^{+} decays. No evidence of CP violation is found. Our results for the triple-product asymmetries are the most precise to date for singly-Cabibbo-suppressed D + decays. Our results for the other asymmetries are the first such measurements performed for charm decays

    We present measurements of the branching fractions for the singly Cabibbo-suppressed decays D+→K+K−π+π0 and D+s→K+π−π+π0, and the doubly Cabibbo-suppressed decay D+→K+π−π+π0, based on 980 fb−1 of data recorded by the Belle experiment at the KEKB e+e− collider. We measure these modes relative to the Cabibbo-favored modes D+→K−π+π+π0 and D+s→K+K−π+π0. Our results for the ratios of branching fractions are B(D+→K+K−π+π0)/B(D+→K−π+π+π0)=(11.32±0.13±0.26)%, B(D+→K+π−π+π0)/B(D+→K−π+π+π0)=(1.68±0.11±0.03)%, and B(D+s→K+π−π+π0)/B(D+s→K+K−π+π0)=(17.13±0.62±0.51)%, where the uncertainties are statistical and systematic, respectively. The second value corresponds to (5.83±0.42)×tan4θC, where θC is the Cabibbo angle; this value is larger than other measured ratios of branching fractions for a doubly Cabibbo-suppressed charm decay to a Cabibbo-favored decay. Multiplying these results by world average values for B(D+→K−π+π+π0) and B(D+s→K+K−π+π0) yields B(D+→K+K−π+π0)=(7.08±0.08±0.16±0.20)×10^−3, B(D+→K+π−π+π0)=(1.05±0.07±0.02±0.03)×10^−3, and B(D+s→K+π−π+π0)=(9.44±0.34±0.28±0.32)×10^−3, where the third uncertainty is due to the branching fraction of the normalization mode. The first two results are consistent with, but more precise than, the current world averages. The last result is the first measurement of this branching fraction

    The oncolytic adenovirus (Ad) is currently being advanced as a promising antitumor remedy as it selectively replicates in tumor cells and can transfer and amplify therapeutic genes. Interleukin (IL)-12 induces a potent antitumor effect by promoting natural killer (NK) cell and cytotoxic T cell activities. IL-18 also augments cytotoxicity of NK cells and proliferation of T cells. This effect further enhances the function of IL-12 in a synergistic manner. Therefore, we investigated for the first time an effective cancer immunogene therapy of syngeneic tumors via intratumoral administration of oncolytic Ad co-expressing IL-12 and IL-18, RdB/IL-12/IL-18. Intratumoral administration of RdB/IL-12/IL-18 improved antitumor effects, as well as increased survival, in B16-F10 murine melanoma model. The ratio of T-helper type 1/2 cytokine as well as the levels of IL-12, IL-18, interferon-gamma and granulocyte-macrophage colony-stimulating factor was markedly elevated in RdB/IL-12/IL-18-treated tumors. Mice injected with RdB/IL-12/IL-18 also showed enhanced cytotoxicity of tumor-specific immune cells. Consistent with these results, immense necrosis and infiltration of NK cells, as well as CD4(+) and CD8(+) T cells, were observed in RdB/IL-12/IL-18-treated tumor tissues. Importantly, tumors treated with RdB/IL-12/IL-18 showed an elevated number of T cells expressing IL-12R beta 2 or IL-18R alpha. These results provide a new insight into therapeutic mechanisms of IL-12 plus IL-18 and provide a potential clinical cancer immunotherapeutic agent for improved antitumor immunity.This work was supported by grants from the Ministry of Knowledge Economy (10030051, Dr C-O Yun), the Korea Science and Engineering Foundation (R15-2004-024-02001-0, 2009K001644, 2010-0029220, Dr C-O Yun), the Korea Food and Drug Administration (KFDA-10172-332 to Dr C-O Yun), and Yonsei University College of Medicine faculty research grant (6-2010-0052, Dr C-O Yun).

    This study was conducted to investigate the seasonal occurrence of aphids and to evaluate efficacy of Carbofuran, Disulfoton and Ortran applied infurrow at the planting time in the field for the control of some aphids on soybean in 1976. Foxglove aphids (Aulacorthum solani) and soybean aphids (Aphis glycines) were dominant species in the soybean field and there were two peaks in the year. The occurrence patterns of aphids were different between visual counting on leaves and in yellow-pans. Carbofuran and Disulfoton showed a good effect for the control of aphids but Ortran was less effectiveOriginating text in Korean.Citation: Hwang, C. Y., Uhm, K. B., Choi, K. M. (1981).
