Models of Innate Neural Attractors and Their Applications for Neural Information Processing.

In this work we reveal and explore a new class of attractor neural networks, based on inborn connections provided by model molecular markers, the molecular marker based attractor neural networks (MMBANN). Each set of markers has a metric, which is used to make connections between neurons containing the markers. We have explored conditions for the existence of attractor states, critical relations between their parameters and the spectrum of single neuron models, which can implement the MMBANN. Besides, we describe functional models (perceptron and SOM), which obtain significant advantages over the traditional implementation of these models, while using MMBANN. In particular, a perceptron, based on MMBANN, gets specificity gain in orders of error probabilities values, MMBANN SOM obtains real neurophysiological meaning, the number of possible grandma cells increases 1000-fold with MMBANN. MMBANN have sets of attractor states, which can serve as finite grids for representation of variables in computations. These grids may show dimensions of d = 0, 1, 2,…. We work with static and dynamic attractor neural networks of the dimensions d = 0 and 1. We also argue that the number of dimensions which can be represented by attractors of activities of neural networks with the number of elements N = 10(4) does not exceed 8.

[Therapeutic approach in locally advanced cervical cancer].

Patients with locally advanced cervical cancer (LACC) consist over 60% of diagnosed cases. They are therapeutic problem, because the more the stage increases,the more survival decreases,the incidence of lymph node metastases and the resistance to the treatment raises. Therapeutic approaches to each one of the stages,consisting the category LACC are presented in this study. Authors reported on the response rate to the applied therapy, operability urvival rate, sites of recurrences and distant metastases and the histopathological the postoperative specimen.

[Content of free and bound water fractions and adhesion properties of sputum in patients with acute focal pneumonia]. / Soderzhanie svobodnoi i sviazannoi fraktsii vody i adgesionnye svoistva mokroty u bol'nykh ostrymi ochagovymi pnevmoniiami.

Dilatometry was used to measure the sputum content of free and bound water in 28 patients with acute focal pneumonias during the acute period of the disease and in the phase of remission. The adhesion properties of the sputum were studied in parallel. The status of the mucociliary defense system was assessed in terms of the time of excretion with the sputum of inhaled own hemoglobin. During the acute disease period, changes in tracheobronchial secretion were identified. They were manifested by high adhesion of the sputum, an increase in it of bound and a reduction of free water fractions. The rate of mucociliary transport was appreciably lowered. During remission, water fractions were found to be redistributed at the expense of the rise of free and decrease of bound ones. That was associated with a decrease of the adhesion properties of the sputum and normalization of mucociliary transport. Therefore, the measurement of water fractions in the sputum is an important diagnostic criterion for evaluation of the status of the mucociliary defense system.
