Hereditary pyrimidine 5'-nucleotidase type-1 (P5’N-1) deficiency is the most frequent disorder of nucleotide metabolism causing hereditary non-spherocytic hemolytic anemia. It is an autosomal recessive disease and is characterized by mild-to moderate hemolytic anemia, reticulocytosis and hyperbilirubinemia. The hallmark of this red cell enzyme disorder is the presence of pronounced basophilic s...

Hovey introduced A-cordial labelings in [4] as a simultaneous generalization of cordial and harmonious labelings. If A is an abelian group, then a labeling f : V (G) → A of the vertices of some graph G induces an edgelabeling on G; the edge uv receives the label f(u) + f(v). A graph G is A-cordial if there is a vertex-labeling such that (1) the vertex label classes differ in size by at most one...

A {P2, P5}-factor of a graph is a spanning subgraph of the graph each of whose components is isomorphic to either P2 or P5, where Pn denote the path of order n. In this paper, we show that if a graph G satisfies c1(G−X)+ 2 3c3(G−X) 6 4 3 |X|+ 1 3 for all X ⊆ V (G), then G has a {P2, P5}-factor, where ci(G − X) is the number of components C of G − X with |V (C)| = i. Moreover, it is shown that a...

We report on an effective cluster expansion of CuBr-linked aggregates by the increase of the steric bulk of the Cp(R) ligand in the pentatopic molecules [Cp(R)Fe(η(5)-P5)]. Using [Cp(BIG)Fe(η(5)-P5)] (Cp(BIG)=C5(4-nBuC6H4)5), the novel multishell aggregate [{Cp(BIG)Fe(η(5:2:1:1:1:1:1)-P5)}12(CuBr)92] is obtained. It shows topological analogy to the theoretically predicted I-C140 fullerene molec...

Let G be a graph. We say that is perfectly divisible if for each induced subgraph H of G, V(H) can partitioned into A and B such H[A] perfect ω(H[B])<ω(H). use Pt Ct to denote path cycle on t vertices, respectively. For two disjoint graphs F1 F2, we F1∪F2 the graph with vertex set V(F1)∪V(F2) edge E(F1)∪E(F2), F1+F2 E(F1)∪E(F2)∪{xy|x∈V(F1) y∈V(F2)}. In this paper, prove (i) (P5,C5,K2,3)-free ar...

An example is presented of a cubic Bézier curve that is the unknot (a knot with no crossings), but whose control polygon is knotted. It is also shown that there is no upper bound on the number of crossings in the control polygon for an unknotted Bézier curve. These examples complement known upper bounds on the number of subdivisions sufficient for a control polygon to be ambient isotopic to its...

Poleroviruses are restricted to vascular phloem tissues from which they are transmitted by their aphid vectors and are not transmissible mechanically. Phloem limitation has been attributed to the absence of virus proteins either facilitating movement or counteracting plant defense. The polerovirus capsid is composed of two forms of coat protein, the major P3 protein and the minor P3/P5 protein,...

Three iridoids (lamalbid (I1), sesamoside (I2) and shanzhiside methyl ester (I3)) and seven polyphenols (cistanoside F (P1), chlorogenic acid (P2), pedalitin-6-O-laminaribioside (P3), pedaliin (P4), isoacteoside (P6), pedalitin (P7) and martynoside (P8)) were identified in young sesame leaves (Sesamum indicum L.) other than the acteoside (P5) reported previously. P3 was a new compound, and I1, ...

Lead is a highly toxic metal and a very strong poison. Lead poisoning usually occurs over a period of months or years. The poisoning can cause severe mental and physical impairment. Young children are most vulnerable to lead poisoning [1-2]. Lead poisoning is accompanied by an acquired deficiency of erythrocyte pyrimidine 5'nucleotidase (P5’N). Genetically determined deficiency of P5’N enzyme w...
