Formation of palmitic acid/Ca(2+) (PA/Ca(2+)) complexes was suggested to play a key role in the non-classical permeability transition in mitochondria (NCPT), which seems to be involved in the PA-induced apoptosis of cardiomyocytes. Our previous studies of complexation of free fatty acids (FFA) with Ca(2+) showed that long-chain (C:16-C:22) saturated FFA had(More)
We suggest several techniques to improve the toric codes and the finite-rate generalized toric codes (quantum hypergraph-product codes) recently introduced by Tillich and Zémor. For the usual toric codes, we introduce the rotated lattices specified by two integer-valued periodicity vectors. These codes include the checkerboard codes, and the family(More)
We study the Simplified Partial Digest Problem (SPDP), which is a mathematical model for a new simplified partial digest method of genome mapping. This method is easy for laboratory implementation and robust with respect to the experimental errors. SPDP is NP-hard in the strong sense. We present an $O(n2^n)$ time enumerative algorithm and an $O(n^{2q})$(More)
The goal of the Simplified Partial Digest Problem (SPDP) is motivated by the reconstruction of the linear structure of a DNA chain with respect to a given nucleotide pattern, based on the multiset of distances between the adjacent patterns (interpoint distances) and the multiset of distances between each pattern and the two unlabeled endpoints of the DNA(More)
Animals can move in not only elegant but also energy efficient ways. Their skin is one of the key components for this achievement. It provides a proper friction for forward motion and can protect them from slipping on a surface during locomotion. Inspired by this, we applied real shark skin to the foot soles of our hexapod robot AMOS. The material is formed(More)
The authors discuss the role of diagnostic biochemical and immunological approaches to evaluation of the curative efficacy of physical training, in particular, its anti-atherosclerotic effects. On the example of the etiopathogenesis of atherosclerosis an analysis is presented of the diagnostic and prognostic value of several tests characterizing the state(More)
