Using molecular dynamics (MD) simulation methods, we attempted to explain the experimental results on ligand specificity of glucose/galactose-binding protein (GGBP) to β-D-glucose and β-D-galactose. For the simulation, a three-dimensional structure of GGBP was prepared, and homology modeling was performed to generate variant structures of GGBP with mutations at Asp14. Then, docking was carried ...
In this paper we study the controllability of the following controlled Ornstein–Uhlenbeck equation z t = 1 2 z − −x, ∇z + ∞ n=1 |β|=n u β (t)b, h β γ d h β , t > 0, x ∈ R d , where h β is the normalized Hermite polynomial, b ∈ L 2 (γ d), γ d (x) = e −|x| 2 π d/2 is the Gaussian measure in R d and the control u ∈ L 2 (0, t 1 ; l 2 (γ d)), with l 2 (γ d) the Hilbert space of Fourier–Hermite coeff...
We consider a G-function F(z)=∑k=0∞Akzk∈K〚z〛, where K is number field, of radius convergence R and annihilated by the G-operator L∈K(z)[d/dz], parameter β∈Q∖Z⩽0. define family G-functions Fβ,n[s](z)=∑k=0∞Ak(k+β+n)szk+n indexed integers s n. Fix α∈K⁎∩D(0,R). Let Φα,β,S be K-vector space generated values Fβ,n[s](α), n∈N, 0⩽s⩽S. show that there exist some positive constants uK,F,β vF,β such uK,F,β...
Evidence indicates low 25-hydroxyvitamin D [(25(OH)D] concentrations in European adolescents. Identification of potential determinants is therefore essential to guide public health initiatives aiming at optimizing vitamin D status across Europe. The aim of the study was to identify potential influencing factors of 25(OH)D concentrations in European adolescents aged 12.5 to 17.5 y, participating...
Solanum melongena is a member of genus that widely cultivated as fruit vegetable in Vietnam. According to Vietnamese traditional medicine, the fruits and whole plants are used treat toothache, turgescence, pruritus, haemorrhoids. As part our project study chemical composition bioactivity Vietnam, five flavonoid glycosides including kaempferol-3-O-β-D-glucopyranoside (1), isovitexin (2), kaempfe...
The study of rhomboid-shaped fully packed loop configurations (RFPLs) is inspired by the work of Fischer and Nadeau on triangular fully packed loop configurations (TFPLs). By using the same techniques as they did some nice combinatorics for RFPLs arise. To each RFPL and to each oriented RFPL a quadruple of binary words (α, β; γ, δ) – its so-called boundary – is assigned. There are necessary con...
New derivatives of d-xylose with aglycons of the most efficient glucose derived inhibitors of glycogen phosphorylase were synthesized to explore the specificity of the enzyme towards the structure of the sugar part of the molecules. Thus, 2-(β-d-xylopyranosyl)benzimidazole and 3-substituted-5-(β-d-xylopyranosyl)-1,2,4-triazoles were obtained in multistep procedures from O-perbenzoylated β-d-xyl...
A set of vertices S resolves a connected graph G if every vertex is uniquely determined by its vector of distances to the vertices in S. The metric dimension of G is the minimum cardinality of a resolving set of G. Let Gβ,D be the set of graphs with metric dimension β and diameter D. It is well-known that the minimum order of a graph in Gβ,D is exactly β + D. The first contribution of this pape...
