Alpha-lipoic Acid: Effects on the Beat-to-Beat Vectorcardiographic Parameters in Type 2 Diabetes Mellitus Patients with Cardiac Autonomic Neuropathy

Objective: Relevance of cardiac autonomic neuropathy has not been fully recognized and there is no standardized treatment protocol.Aim: To evaluate the effects of alpha-lipoic acid on the beat-to-beat vectorcardiographic parameters, namely spatial QRS-T angle, QT dispersion (QTd) and corrected QT interval (QTc) in type 2 diabetes mellitus persons with cardiac autonomic neuropathy. Research designs and methods: Our study involved 33 persons with definite stage of cardiac autonomic neuropathy and diabetes mellitus type 2, which were assigned to each of two groups: one took standard antihyperglycaemic treatmen (n=15, control group) and the other (n=18) in addition to standard therapy - 600 mg of alpha-lipoic acid daily for three months. The analysis of vectorcardiographic parameters was performed. Results: It was found out that alpha-lipoic acid contributed to decrease of the vectorcardiographic parameters, namely QRS-T angle, QTd and QTc. Conclusions: The positive influences of alpha-lipoic acid suggest the usefulness of its prescription to type 2 diabetes mellitus persons with definite stage of cardiac autonomic neuropathy. The efficacy of alpha-lipoic acid is the result of its direct effect on the parameters of vectorcardiography

Minimal Length Maximal Green Sequences and Triangulations of Polygons

We use combinatorics of quivers and the corresponding surfaces to study maximal green sequences of minimal length for quivers of type $\mathbb{A}$. We prove that such sequences have length $n+t$, where $n$ is the number of vertices and $t$ is the number of 3-cycles in the quiver. Moreover, we develop a procedure that yields these minimal length maximal green sequences.Comment: 22 pages, 1 figur

A dermatoglyphics of foot in the prognosis of sporting gift: differential distinctions of dermatoglyphics of foot for sportsmen and people which do not go in for sports

The features of forming of dermatoglyphics of feet are compared for sportsmen and people, which do not go in for sports. In researches took part 209 men and 198 women in age 17-19 years, which did not go in for systematic sports. The quantitative and high-quality indexes of dermatoglyphics of fingers and soles of foot were determined on a method T.D. Gladkova. It is certain that as genetic markers of propensity to the sporting gift there can be more difficult dermatoglyphics patterns (W) on the first finger and soles of feet and more considerable indexes of comb-shaped count on the first tiptoes. A dermatoglyphics of fingers and hands of hands is more informing in a prognosis high motive gift, than dermatoglyphics of feet. It can be predefined that is analysed greater amount of indexes of dermatoglyphics of hands as compared to feet. Probability of genetic prognosis is more high for girls, what for boys
