Numerous studies have shown that consumption of soybean products decrease the risk of cancers in humans. Experiments at the molecular level have demonstrated that in most cases proteins and peptides are responsible for the anticancer properties of soybeen. Special attention should be paid to lunasin - a peptide described for the first time 16 years ago. Due to its structure it causes i.a., inhi...
We investigate the relationship between the eigenvalues of a graph G and fractional spanning tree packing and coverings of G. Let ω(G) denote the number of components of a graph G. The strength η(G) and the fractional arboricity γ (G) are defined by η(G) = min |X | ω(G − X) − ω(G) , and γ (G) = max |E(H)| |V (H)| − 1 , where the optima are taken over all edge subsets X whenever the denominator ...
The decays B + → J/ ψ3π + 2π − and B + → ψ (2S)π + π + π − are observed for the first time using a data sample corresponding to an integrated luminosity of 3.0 fb −1 , collected by the LHCb experiment in proton–proton collisions at the centre-of-mass energies of 7 and 8 TeV. The branching fractions relative to that of B + → ψ (2S)K + are measured to be B(B + → J/ ψ3π + 2π −) B(B + → ψ (2S)K +) ...
Using 14 million ψ(2S) events collected with the BESII detector, branching fractions of ψ(2S) → K(892)K+c.c. and K(892)K 0 + c.c. are determined to be: B(ψ(2S) → K(892)K + c.c.) = (2.9 −1.7 ± 0.4) × 10 −5 and B(ψ(2S) → K(892)K 0 + c.c.) = (13.3 −2.7 ± 1.7)× 10 . The results confirm the violation of the “12% rule” for these two decay channels. A large isospin violation between the charged and ne...
Three new (2-4) and one known (1) sphingolipid were identified in the MeOH extract of Bombycis Corpus 101A. Their structures were elucidated as (4E,2S,3R)-2-N-octadecanoyl-4-tetradecasphingenine (1), (4E,6E,2S,3R)-2-N-eicosanoyl-4,6-tetradecasphingadienine (2), (4E,2S,3R)-2-N-eicosanoyl-4-tetradecasphingenine (3), and (4E,6E,2S,3R)-2-N-docosanoyl-4,6-tetradecasphingadienine (4) on the basis of ...
(2S,3S)-2,3-Butanediol ((2S,3S)-2,3-BD) is a potentially valuable liquid fuel and an excellent building block in asymmetric synthesis. In this study, cofactor engineering was applied to improve the efficiency of (2S,3S)-2,3-BD production and simplify the product purification. Two NADH regeneration enzymes, glucose dehydrogenase and formate dehydrogenase (FDH), were introduced into Escherichia c...
We prove the existence of a positive SOLA (Solutions Obtained as Limits Approximations) to following PDE involving fractional power Laplacian ( ? ? ) s u = 1 ? + ? 2 ? ? in ? , > 0 ? N ? .

Chickpea is a key crop in sustainable cropping systems and for its nutritional value. Studies on agronomic genetic influences chickpea protein composition are missing. In order to obtain deep insight into the response of chickpeas management relation quality traits, two-year field trial was carried out with eight genotypes under an organic conventional system. Protein assessed by SDS-PAGE main ...
An orientation of a graph G is a mod(2s + 1)-orientation if under this orientation, the net out-degree at every vertex is congruent to zero mod(2s + 1). If for any function b : V (G) → Z2s+1 satisfying v∈V (G) b(v) ≡ 0 (mod 2s + 1), G always has an orientation D such that the net out-degree at every vertex v is congruent to b(v) mod (2s + 1), then G is strongly Z2s+1-connected. In this paper,...
