A Russian national computing and communication system designed to assist non-specialized physicians in the diagnosis and treatment of craniocerebral injury is described

ВОЛНОВАЯ СТРУКТУРА РИТМА СЕРДЦА У БОЛЬНЫХ ОСТРЫМ ИНФАРКТОМ МИОКАРДА С ПОДЪЕМОМ СЕГМЕНТА ST В ЗАВИСИМОСТИ ОТ СПОСОБА РЕВАСКУЛЯРИЗАЦИИ

The authors studied the wave nature of the heart rate in the patients with acute myocardial infarction with ST segment elevation depending on the method of revascularization. Ninety-four male patients (mean age - 54.41±0.86 ys) without myocardial infarction in their past medical hystories participated in the study.Изучены волновая структура ритма сердца у больных острым инфарктом миокарда с подъемом сегмента ST в зависимости от способа реваскуляризации миокарда. С этой целью обследованы 94 мужчины (средний возраст - 54,41±0,86 года), не имеющих в анамнезе данных о перенесенном ранее инфаркте миокарда

Ontogenetic variability in external morphology of round goby Neogobius melanostomus from Middle Danube, Slovakia

In the previous decade, four species of non-native goby have invaded the middle section of the River Danube. To understand the problems associated with these invasions better, we examined the external morphology of 184 round goby Neogobius melanostomus specimens using both triple regression (distance-based measurements) and geometrical (coordinates-based measurements) analysis within an ontogenetical and epigenetical aspect. Using geometrical analysis of distance-based characters, we found that the external body shape in four size groups of round goby remained essentially unchanged. Such direct development represents a strongly precocial (i.e. specialized) life-history, whereas earlier maturation in this non-native population suggests a shift back towards more altricial (i.e. less specialized, more generalized) life history. This combination of altricial–precocial trajectories seems to be typical for invasive round gobies and may be one of key factors for their successful colonization of new environments

Current strategies for the assessment and evaluation of genetic diversity in chicken resources

Chicken genetic resources comprise a wide range of breeds and populations including red jungle fowl (the assumed progenitor of all domestic breeds), native and fancy breeds, middle level food producers, industrial stocks and specialised lines. Based on the suggestion that the more distant a breed or population is the more likely it is to carry unique genetic features, the assessment of genetic distances by means of molecular marker information may provide useful information for initial evaluation of chicken genetic resources. During the last two decades several molecular marker classes have become available. Variable numbers of tandem repeat loci, in particular microsatellites, have been successfully used in chicken diversity studies. Genetic diversity measures using the highly polymorphic variable number of tandem repeat lociyield reliable and accurate information for the study of genetic relationships between chicken populations. First results of the European project on chicken biodiversity (AVIANDIV) obtained from microsatellite typing in DNA pools of 51 diverse chicken breeds showed that jungle fowl populations, traditional unselected breeds and broiler lines appear to be widely heterogeneous populations that may include a large portion of the genetic diversity of the tested breeds. In contrast, highly selected strains (layers and experimental lines) are characterised by a lower polymorphism. They behave as outliers from the set of breeds sampled. Single nucleotide polymorphism is a new and very promising molecular marker system which offers opportunities to assess the genetic diversity in farm animal species differently by investigating the mode and extent of changes in certain positions in the genome
