Abstract:
Let G be a simple graph and let G- denote its complement. We say that G is integral if its spectrum consists of integral values. Let Kxa, yb = Ka,a,...,a,b,b...,b be the complete m-partite graph with xa + yb vertices where x and y are positive integers and m = x + y. In this work we consider integral graphs which belong to the class ?Kxa,yb for any ? > 1 and a > b where mG denotes the m-fold union of the graph G.

Abstract Abstract 1468 Background: Increased YB-1 expression correlates with poor prognosis, drug resistance and metastasis in several different cancers including B cell lymphoma. Phosphorylation and nuclear localization of YB-1 in response to growth factors leads to increased survival through expression of proteins such as survivin and multidrug resistance protein 1. Until now, its role in leukemia has not been investigated. We hypothesized that YB-1 expression is aberrantly regulated in pediatric pre-B acute lymphoblastic leukemia (pre-B ALL), and that YB-1 may be activated downstream of IL-

Abstract:
AbstractMelanoma is the most lethal dermal tumor, and a high recurrence rate and skin defects are two main serious problems. An antimelanoma material,which effectively inhibits tumor recurrence and possesses excellent biocompatibility, is urgently needed to treat melanoma. In this study, we developed a novel antitumor Yb3+ [Yb(NO3)3]containing chitosan hydrogel (Yb-CS hydrogel) by dissolving Yb(NO3)3 and chitosan in acetic acid solution and forming composite hydrogels by a freeze-drying process after adding NaOH to the mixed solution. In vitro studies demonstrated that the Yb3+ produces effect

Abstract:
Bulky monomeric lanthanoid(III) aryl oxides Ln(Odpp)3(Odpp = 2,6- diphenylphenoxide; Ln = Nd, Sm, Er, Yb or Lu) have been prepared by reaction between the lanthanoid metal, Hg(C6F5)2, and HOdpp in tetrahydrofuran (thf), and Yb(Odpp)3 has also been obtained from an analogous reaction of (PhCC)2Hg. Cleavage of Ln(η5-C5H5)3 (Ln = Nd or Yb) with HOdpp also yields Ln(Opdd)3. The aryl oxides have been isolated as [Ln(Odpp)3(thf)2] (Ln = Nd, Sm or Yb) or as the homoleptic complexes Ln(Odpp)3 (Ln = Nd, Er, Yb or Lu).

Abstract:
Fusarium crown rot caused by Fusarium pseudograminearum is one of the most devastating diseases of wheat worldwide causing major yield and economic losses. In this study, strain YB-15 was isolated from soil of wheat rhizosphere and classified as Bacillus subtilis by average nucleotide identity analysis. It significantly reduced Fusarium crown rot with a control efficacy of 81.50% and significantly improved the growth of wheat seedlings by increasing root and shoot fresh weight by 11.4% and 4.2%, respectively. Reduced Fusarium crown rot may have been due to direct antagonism by the production o

Abstract:
The Y box is a conserved sequence in the promoter of major histocompatibility complex (MHC) class II genes, which contains a CCAAT sequence (CCAAT box). Previously, we partially purified the DNA-binding protein that recognizes the Y box of the I-Aβ gene and showed that it consisted of two components (factors A and B) both of which were necessary for optimal DNA binding. The genes for the heteromeric protein NF-Y (NF-YA and NF-YB), which binds to the I-Eα Y box have been cloned. We subsequently isolated the genes for NF-YA and NF-YB using oligonucleotides designed from the published sequences.
