objective: people are usually susceptible to carcinogenic aromatic amines, present in cigarrette smoke and polluted environment, which can cause dna damage. therefore, maintenance of genomic dna integrity is a direct result of proper function of dna repair enzymes. polymorphic diversity could affect the function of repair enzymes and thus augment the risk of different cancers. xeroderma pigment...

Introduction Asymmetry between odd and even echoes generates Nyquist ghost artifact in a single-shot EPI , and further enhances multiple ghost artifacts in a segmented EPI. These ghost artifacts not only severely degrade EPI image quality, but may lead to incorrect ADC values in EPI based diffusion measurements (1). Methods currently available for odd-even-echo asymmetry compensation include on...

Cellular networks are generally modeled as node-weighted graphs, where the nodes represent cells and the edges represent the possibility of radio interference. An algorithm for the channel assignment problem must assign as many channels as the weight indicates to every node, such that any two channels assigned to the same node satisfy the co-site constraint, and any two channels assigned to adj...

OBJECTIVES To explore the effect of vitamin D supplementation in prevention of respiratory tract infections on the basis of published clinical trials. MATERIALS AND METHODS Clinical trials were searched from various electronic databases. Five clinical trials were suitable for inclusion. Outcome was events of respiratory tract infections in vitamin D group and placebo group. Data was reported ...

Abstract An odd wheel graph is a formed by connecting new vertex to all vertices of an cycle. We answer question Rosenfeld and Le showing that wheels cannot be drawn in the plane so lengths edges are integers.

Lepton flavor violating processes μ → eγ and μ → 3e with polarized muons are studied in the supersymmetric grand unified theory (SUSY GUT). As a result of a detailed numerical calculation, it is shown that the Pand T-odd asymmetries defined with the help of the muon polarization and the ratio of two branching fractions make a good contrast between the SU(5) and SO(10) SUSY GUT. These observable...
