    Not AvailableSeasonal outbreaks of swine erysipelas have been reported in back yard pig farms in the Phek district of Nagaland, India. The alpha haemolytic isolate of Erysipelothrix rhusiopathiae was recovered on blood agar from the clinical samples. The organisms were confirmed microscopically, biochemical analysis as well as by polymerase chain reaction (PCR) amplification of 16S rRNA gene and sequence analysis. These Nagaland isolates (KT160358, KT160359) were closely related to the type spp. E. rhusiopathiae in phylogenetic analysis and forms the same clad with Chineese isolates of swine and murine origin indicating an epidemiological link. The isolates were found to be most sensitive to oxytetracycline and responded to treatment. Swine erysipelas occurred in Phek district in a season due to sudden change of weather and temperature. Pigs exposed to such predisposing factors probably favoured to propagation of already persisted organisms in pigs. This is the first confirmed case of E. rhusiopathiae infection from the NE states of Nagaland, India.Not Availabl

    Antioxidative, Hemocompatible, Fluorescent Carbon Nanodots from an “End-of-Pipe” Agricultural Waste: Exploring Its New Horizon in the Food-Packaging Domain

    The attention of researchers is burgeoning toward oilseed press-cake valorization for its high protein content. Protein removal from oil-cakes generates large quantities of fibrous residue (oil-and-protein spent meal) as a byproduct, which currently has very limited practical utility. In the wake of increasing awareness in waste recycling, a simple environmentally benign hydrothermal carbonization process to convert this “end-of-pipe” waste (spent meal) into antioxidative, hemocompatible, fluorescent carbonaceous nanoparticles (FCDs) has been described. In the present investigation, an interesting application of FCDs in fabricating low-cost rapeseed protein-based fluorescent film, with improved antioxidant potential (17.5–19.3-fold) and thermal stability has been demonstrated. The nanocomposite film could also be used as forgery-proof packaging due to its photoluminescence property. For assessing the feasibility of antioxidative FCDs in real food systems, a comparative investigation was further undertaken to examine the effect of such nanocarbon-loaded composite film on the oxidative shelf life of rapeseed oil. Oil samples packed in nanocomposite film sachets showed significant delay in oxidative rancidity compared to those packed in pristine protein-film sachet (free fatty acids, peroxide value, and thiobarbituric acid-reactive substances reduced up to 1.4-, 2-, and 1.2-fold, respectively). The work presents a new concept of biobased fluorescent packaging and avenues for harnessing this potent waste

    International audienceWe present measurements of the branching fractions for the singly Cabibbo-suppressed decays D+K+Kπ+π0D^+\to K^{+}K^{-}\pi^{+}\pi^{0} and Ds+K+ππ+π0D_s^{+}\to K^{+}\pi^{-}\pi^{+}\pi^{0}, and the doubly Cabibbo-suppressed decay D+K+ππ+π0D^{+}\to K^{+}\pi^{-}\pi^{+}\pi^{0}, based on 980 fb1{\rm fb}^{-1} of data recorded by the Belle experiment at the KEKB e+ee^{+}e^{-} collider. We measure these modes relative to the Cabibbo-favored modes D+Kπ+π+π0D^{+}\to K^{-}\pi^{+}\pi^{+}\pi^{0} and Ds+K+Kπ+π0D_s^{+}\to K^{+}K^{-}\pi^{+}\pi^{0}. Our results for the ratios of branching fractions are B(D+K+Kπ+π0)/B(D+Kπ+π+π0)=(11.32±0.13±0.26)%B(D^{+}\to K^{+}K^{-}\pi^{+}\pi^{0})/B(D^{+}\to K^{-}\pi^{+}\pi^{+}\pi^{0}) = (11.32 \pm 0.13 \pm 0.26)\%, B(D+K+ππ+π0)/B(D+Kπ+π+π0)=(1.68±0.11±0.03)%B(D^{+}\to K^{+}\pi^{-}\pi^{+}\pi^{0})/B(D^{+}\to K^{-}\pi^{+}\pi^{+}\pi^{0}) = (1.68 \pm 0.11\pm 0.03)\%, and B(Ds+K+ππ+π0)/B(Ds+K+Kπ+π0)=(17.13±0.62±0.51)%B(D_s^{+}\to K^{+}\pi^{-}\pi^{+}\pi^{0})/B(D_s^{+}\to K^{+}K^{-}\pi^{+}\pi^{0}) = (17.13 \pm 0.62 \pm 0.51)\%, where the uncertainties are statistical and systematic, respectively. The second value corresponds to (5.83±0.42)×tan4θC(5.83\pm 0.42)\times\tan^4\theta_C, where θC\theta_C 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+Kπ+π+π0)B(D^{+}\to K^{-}\pi^{+}\pi^{+}\pi^{0}) and B(Ds+K+Kπ+π0)B(D_s^{+}\to K^{+}K^{-}\pi^{+}\pi^{0}) yields B(D+K+Kπ+π0)=(7.08±0.08±0.16±0.20)×103B(D^{+}\to K^{+}K^{-}\pi^{+}\pi^{0})= (7.08\pm 0.08\pm 0.16\pm 0.20)\times10^{-3}, B(D+K+ππ+π0)=(1.05±0.07±0.02±0.03)×103B(D^{+}\to K^{+}\pi^{-}\pi^{+}\pi^{0})= (1.05\pm 0.07\pm 0.02\pm 0.03)\times10^{-3}, and B(Ds+K+ππ+π0)=(9.44±0.34±0.28±0.32)×103B(D_s^{+}\to K^{+}\pi^{-}\pi^{+}\pi^{0}) = (9.44\pm 0.34\pm 0.28\pm 0.32)\times10^{-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

    We measure the ratio of branching fractions for the Υ(4S)\Upsilon (4S) decays to B+BB^+B^- and B0Bˉ0B^0\bar{B}{}^0 using B+J/ψ()K+B^+ \rightarrow J/\psi(\ell\ell) K^+ and B0J/ψ()K0B^0 \rightarrow J/\psi(\ell\ell) K^0 samples, where J/ψ()J/\psi(\ell\ell) stands for J/ψ+J/\psi \to \ell^+\ell^- (=e\ell = e or μ\mu), with 711711 fb1^{-1} of data collected at the Υ(4S)\Upsilon(4S) resonance with the Belle detector. We find the decay rate ratio of Υ(4S)B+B\Upsilon(4S) \rightarrow B^+B^- over Υ(4S)B0Bˉ0\Upsilon(4S) \rightarrow B^0\bar{B}{}^0 to be 1.065±0.012±0.019±0.0471.065\pm0.012\pm 0.019 \pm 0.047, which is the most precise measurement to date. The first and second uncertainties are statistical and systematic, respectively, and the third uncertainty is systematic due to the assumption of isospin symmetry in BJ/ψ()KB \to J/\psi(\ell\ell) K

    We present a study of a singly Cabibbo-suppressed decay Λc+pKS0KS0\Lambda_c^+\to{}pK_S^0K_S^0 and a Cabibbo-favored decay Λc+pKS0η\Lambda_c^+\to{}pK_S^0\eta based on 980 fb1\rm fb^{-1} of data collected by the Belle detector, operating at the KEKB energy-asymmetric e+ee^+e^- collider. We measure their branching fractions relative to Λc+pKS0\Lambda_c^+\to{}pK_S^0: B(Λc+pKS0KS0)/B(Λc+pKS0)=(1.48±0.08±0.04)×102\mathcal{B}(\Lambda_c^+\to{}pK_S^0K_S^0)/\mathcal{B}(\Lambda_c^+\to{}pK_S^0)={(1.48 \pm 0.08 \pm 0.04)\times 10^{-2}} and B(Λc+pKS0η)/B(Λc+pKS0)=(2.73±0.06±0.13)×101\mathcal{B}(\Lambda_c^+\to{}pK_S^0\eta)/\mathcal{B}(\Lambda_c^+\to{}pK_S^0)={(2.73\pm 0.06\pm 0.13)\times 10^{-1}}. Combining with the world average B(Λc+pKS0)\mathcal{B}(\Lambda_c^+\to{}pK_S^0), we have the absolute branching fractions: B(Λc+pKS0KS0)=(2.35±0.12±0.07±0.12)×104\mathcal{B}(\Lambda_c^+\to{}pK_S^0K_S^0) = {(2.35\pm 0.12\pm 0.07 \pm 0.12 )\times 10^{-4}} and B(Λc+pKS0η)=(4.35±0.10±0.20±0.22)×103\mathcal{B}(\Lambda_c^+\to{}pK_S^0\eta) = {(4.35\pm 0.10\pm 0.20 \pm 0.22 )\times 10^{-3}}. The first and second uncertainties are statistical and systematic, respectively, while the third ones arise from the uncertainty on B(Λc+pKS0)\mathcal{B}(\Lambda_c^+\to{}pK_S^0). The mode Λc+pKS0KS0\Lambda_c^+\to{}pK_S^0K_S^0 is observed for the first time and has a statistical significance of > ⁣10σ>\!10\sigma. The branching fraction of Λc+pKS0η\Lambda_c^+\to{}pK_S^0\eta has been measured with a threefold improvement in precision over previous results and is found to be consistent with the world average
