Abstract Human infants are born neurologically immature, but whether this originates from conflicting selection pressures between bipedal locomotion and encephalization as suggested by the obstetrical dilemma remains controversial. Australopithecines are ideal for investigating this trade-off as they have a bipedally adapted pelvis, yet relatively small brains. Our finite-element birth simulations based on different pelvic reconstructions and a range of fetal head sizes indicate that australopithecines already possessed a human-like rotational birth pattern. Since only newborn head sizes smaller than those predicted for non-human primates leave adequate space for soft tissue between the bony pelvis and fetal skull, our data imply that australopithecines had secondarily altricial newborns and likely evolved cooperative breeding to care for their helpless infants. These prerequisites for advanced cognitive development therefore seem to have been corollary to skeletal adaptations to bipedal locomotion that preceded the appearance of the genus Homo and the increase in encephalization.

The kidney plays a fundamental role in the regulation of arterial blood pressure and fluid/electrolyte homeostasis. As congenital anomalies of the kidney and urinary tract (CAKUT) constitute one of the most common human birth defects, improved understanding of the cellular and molecular mechanisms that lead to CAKUT is critical. Accumulating evidence indicates that aberrant signaling via receptor tyrosine kinases (RTKs) is causally linked to CAKUT. Upon activation by their ligands, RTKs dimerize, undergo autophosphorylation on specific tyrosine residues, and interact with adaptor proteins to activate intracellular signal transduction pathways that regulate diverse cell behaviours such as cell proliferation, survival, and movement. Here, we review the current understanding of role of RTKs and their downstream signaling pathways in the pathogenesis of CAKUT.

This paper presents an engineering analysis of shoulder dystocia (SD) in the human birth process which usually results in damaging the brachial plexus nerves and the humerus and/or clavicle bones of the baby. The goal is to study these injuries from the mechanical engineering point of view. Two separate finite element models of the neonatal neck and the clavicle bone have been simulated using eight-node three-dimensional elements and beam elements respectively. Simulated models have been analysed under suitable boundary conditions using the ‘SAP80’ finite element package. Finally, results obtained have been verified by comparing them with published clinical and experimental observations.

UNSTRUCTURED Childbirth is a physiologic process with significant medical risk, as neurological impairment due to the birthing process can occur at any time. Improvements in risk assessment and anticipatory interventions are constantly needed; however, the birthing process is difficult to assess using simple imaging technology since the maternal bony pelvis and fetal skeleton interfere with visualizing the soft tissues. Magnetic resonance imaging (MRI) is a non-invasive technique with no ionizing radiation that can monitor the biomechanics of the birthing process. Effective utilization of this modality, however, requires teamwork and implementation of the appropriate safeguards to achieve appropriate safety levels. This article describes a clinically effective and safe method to perform real-time MRI during the birthing process. We report the experience of our team as part of the IMAGINAITRE research protocol (France), which aimed better understand of the biomechanics of childbirth.

The socio-economic development of the country is the goal of every state. An important element in achieving this goal is the availability and application of a macroeconomic generalizing indicator that reveals the purpose of public policy. The main aim of the study is to identify the socio-economic characteristics of the organization of life in the countries of Scandinavia, using the macroeconomic generalizing indicator RAZ (the name of the indicator is based on the first part of the Russian word “razvitie” translated as “development”), proposed by the authors. The authors consider this indicator as suitable for cross-country comparisons of the quality of life and an objective estimation of development of the society from the point of view of focusing on the maximum disclosure of person's abilities and personal development. The research was based on the methods of analysis, synthesis, comparison, generalization and modeling, as well as on the case-study method. The use of these methods made it possible to identify the characteristics of the socio-economic organization of life and characteristics defining quality of life (human birth, education and medical care) in their composition, and also the indicators corresponding to them characterizing qualitative changes — levels of human birth rate, education and medical care. The generalized estimation of the specified characteristics defining quality of life, it is offered to make by means of a macroeconomic generalizing indicator. For its calculation a set of the quantity indicators defining quality of life (population in the country, number of the persons trained in an education system and number of healthy people) is generated. The authors make an assessment of the macroeconomic generalizing indicator and the set of the quantity indicators defining quality of life (the population in the country, the number of healthy people and the number of people studying in the education system).The study has developed an approach to calculating defining quality of life indicators using the System of National Accounts according to the data of the European Bureau of Statistical Research and the official websites of the national statistical services of the countries of Scandinavia and Switzerland as a country that has indicators close to the leading values of the countries of Scandinavia. These estimates can be used for comparative analysis purposes. The study compiled a rating of countries according to the macroeconomic generalizing indicator. According to calculations, Norway occupies a leading position. The lowest rank is observed in Sweden. There are changes in the quality of life in society, and this complex phenomenon requires an objective assessment. Generalizing indicator of the development provides such an assessment. The indicator allows us to evaluate the set of characteristics that determine the quality of life, which is not yet taken into account in cross-country comparisons, and to compare them. It has been established that the lack of development of the conceptual apparatus and the unavailability of important statistical information complicate the principle of compiling the indicator and lead to an inaccurate calculation of the macroeconomic generalizing indicator at this study stage. Nevertheless, it was found out that the calculation could be made in relation to the following levels: humanity (world), country, region or city. Further research is planned to study substantiation of the conceptual device of formation of RAZ as indicator for cross-country comparisons of quality of life and an objective estimation of development of the society, as well as for using it as a modelling element of social and economic systems. Besides, it is necessary to develop additional characteristics that take into account the influence of a person’s life expectancy on the quality of his life, as well as in clarifying the conceptual apparatus for forming a macroeconomic generalizing indicator RAZ for building a rational organization of people's place of residence. This approach creates new theoretical and methodological foundations for scientific knowledge of the socio-economic development of the countries and allows us to analyze the quality of life as a base which moves development of the countries in different historical periods and to see the development of the world in the future in a different way.
