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.

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
Measurement of the branching fractions for Cabibbo-suppressed decays and at Belle
International audienceWe present measurements of the branching fractions for the singly Cabibbo-suppressed decays and , and the doubly Cabibbo-suppressed decay , based on 980 of data recorded by the Belle experiment at the KEKB collider. We measure these modes relative to the Cabibbo-favored modes and . Our results for the ratios of branching fractions are , , and , where the uncertainties are statistical and systematic, respectively. The second value corresponds to , where 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 and yields , , and , 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
Measurement of the production ratio in collisions at the resonance using decays at Belle
We measure the ratio of branching fractions for the decays to and using and samples, where stands for ( or ), with fb of data collected at the resonance with the Belle detector. We find the decay rate ratio of over to be , 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
Measurement of branching fractions of and at Belle
We present a study of a singly Cabibbo-suppressed decay and a Cabibbo-favored decay based on 980 of data collected by the Belle detector, operating at the KEKB energy-asymmetric collider. We measure their branching fractions relative to : and . Combining with the world average , we have the absolute branching fractions: and . The first and second uncertainties are statistical and systematic, respectively, while the third ones arise from the uncertainty on . The mode is observed for the first time and has a statistical significance of . The branching fraction of has been measured with a threefold improvement in precision over previous results and is found to be consistent with the world average
