Unlike nuclear (n)DNA, of which there is one paired copy per cell, there are many copies of mitochondrial (mt)DNA per cell, making PCR amplification of mtDNA easier in samples of limited cellularity. The aims of this study were to (i) determine the mutation patterns of breast cancers through a comprehensive screen of mtDNA mutations, and (ii) assess if mutations in the cancers are also detectab...

Using the method of Chetyrkin, Misiak, and Münz we calculate analytically a class of three-loop vacuum diagrams with two different mass values, one of which is one-third as large as the other. In particular, this specific mass ratio is of great interest in relation to the three-loop effective potential of the O(N) φ4 theory. All pole terms in ǫ = 4−D (D being the space-time dimensions in a dime...

Background: Recently, the surgical methods are used in patients with anterior cruciate ligament rupture and have been associated with successful results. There are different results in the term of using of the surgical methods for anterior cruciate ligament that often is associated with some complications such as infection, static laxity, remaining the pain, need to recurrence surgery, and limi...

RecQ DNA helicases are critical for preserving genome integrity. Of the five RecQ family members identified in humans, only the Werner syndrome protein (WRN) possesses exonuclease activity. Loss of WRN causes the progeroid disorder Werner syndrome which is marked by cancer predisposition. Cellular evidence indicates that WRN disrupts potentially deleterious intermediates in homologous recombina...

Exact numerical minimization of interface energies is used to test the functional renormalization group analysis for interfaces pinned by quenched disorder. The fixed-point function R(u) (the correlator of the coarse-grained disorder) is computed. In dimensions D=d+1, a linear cusp in R''(u) is confirmed for random bond (d=1, 2, 3), random field (d=0, 2, 3), and periodic (d=2, 3) disorders. The...

The hybrid formalism for the superstring is used to compute one-loop amplitudes with an arbitrary number of external d=4 supergravity states. These one-loop N-point amplitudes are expressed as Koba-Nielsen-like formulas with manifest d=4 supersymmetry.

It is showed that the very recently introduced Lagrangian loop formulation of the lattice Maxwell theory is equivalent to the Villain form in 2+1 dimensions. A transparent description of the classical loop action is given in pure geometrical terms for the 2 + 1 and 3 + 1 dimensional cases. The loop formalism was introduced some time ago as a general analytical Hamiltonian approach based on the ...

The pair (GH , ·) is called a special loop if (G, ·) is a loop with an arbitrary subloop (H, ·) called its special subloop. A special loop (GH , ·) is called a second Smarandache Bol loop (S2ndBL) if and only if it obeys the second Smarandache Bol identity (xs · z)s = x(sz · s) for all x, z in G and s in H. The popularly known and well studied class of loops called Bol loops fall into this clas...
