OBJECTIVE Single nucleotide polymorphisms (SNPs) accumulated frequently in the mitochondrial displacement loop (D-loop) in many cancers. We had identified cancer risk-associated SNPs in the D-loop of non-Hodgkin lymphoma (NHL) patients previously, in this study, we investigated the association of age at onset and D-loop SNPs in NHL patients. MATERIALS AND METHODS The D-loop region of mtDNA wa...

We show that the one- and two-loop $\beta$-functions of closed, bosonic string can be written in a manifestly O($D$,$D$)-covariant form. Based on this result, we prove 1) Poisson-Lie symmetric $\sigma$-models are renormalisable 2) their invariant under T-duality. Moreover, identify distinguished scheme which symmetry is manifest. It simplifies calculation significantly thereby provides powerful...

Genetic diversity as an important marker of the ecological status of aquatic ecosystems is considered a unique and powerful tool to evaluate biological communities. In order to evaluate the genetic diversity among golden mullet species (Liza aurata) in the southeast and southwest coasts of the Caspian Sea by D-Loop gene sequencing, a total of 23 fin specimens of golden mullet were collected fro...

The displacement loop (D loop) is a DNA strand invasion product formed during homologous recombination. Disruption of nascent D loops prevents recombination, and during synthesis-dependent strand annealing (SDSA), disruption of D loops extended by DNA polymerase ensures a non-crossover outcome. The proteins implicated in D loop disruption are DNA motor proteins/helicases that act by moving DNA ...

We investigate the ${B}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{K}^{+}X(3872)$ decay via ${D}_{s1}(2536)\overline{D}{D}^{*}$ rescattering diagram. The line shape of ${K}^{+}X(3872)$ distribution curve around ${D}_{s1}(2536)\overline{D}$ threshold is very sensitive to $X(3872)$ mass because triangle singularity (TS) can be generated from loop. By means this characteristic,...

Protein-tyrosine phosphatases (PTPs) and protein-tyrosine kinases co-regulate cellular processes. In pathogenic bacteria, they are frequently exploited to act as key virulence factors for human diseases. Mycobacterium tuberculosis, the causative organism of tuberculosis, secretes a low molecular weight PTP (LMW-PTP), MptpA, which is required for its survival upon infection of host macrophages. ...

In type-II string theory compactifications on Calabi-Yau manifolds, topological string theory partition functions give a class of exact F-terms in the four dimensional effective action. We point out that in the background of constant self-dual field strength, these terms deform the central charges for D-branes wrapping Calabi-Yau manifold to include string loop corrections. We study the corresp...

The Caspian Sea and its basin (e.g. Anzali wetland) is one of the natural habitats of wild common carp Cyprinus carpio. In this study the genetic structure of this species. In the south-west of Caspian Sea (the Anzali wetland) was investigated using PCR-RFLP analysis of D-loop region. Two hundred of mature fish were collected from 5 stations (40 individuals from each station) including Siahkesh...

M that maintain fidelity and repair mistakes are ubiquitous throughout the protein biosynthesis pathway (1). The aminoacyl tRNAs serve as critical turning points in translation, because they link the nucleic acid genetic code with the amino acid building blocks of proteins. Misacylation of tRNAs can have devastating results, affecting the very survivability of an organism. Accuracy in tRNA amin...
