Systemic analysis: Individual typological characteristics of the human body

Statistical analysis of the distribution of the mean somatometric, functional, and psychophysiological parameters in the total sample of subjects with the use of the χ² and λ tests and low, medium, and high habitual physical activity (HPA) levels (LHPA, MHPA, and HHPA, respectively) at different ontogenetic stages (junior and senior school students and young adults of both sexes) showed wide quantitative and qualitative ranges of psychophysiological individuality in a healthy population and demonstrated that it is reasonable to distinguish three typological groups or functional constitutional types (FT-1 corresponding to LHPA; FT-2, to MHPA; and FT-3, to HHPA). Typical first- and second-order parameters, as well as the results of third-order tests characterizing the current state, were determined for each FT. In order to comprehensively assess the constitutional type (synthetic constitution) of the subjects with low, medium, and high HPAs, the integrated analysis of the set of their characteristics was performed using the principles of polythetic (multi-variate) classification. The results obtained using multivariate statistical methods confirmed the basic postulate of the concept of typological variability of physiological individuality that a healthy human population is qualitatively heterogeneous in morphological, functional, and psychophysiological traits. The integrated physiological and statistical analyses of the results provided a scientific basis for three functional constitutional types (FT-1, FT-2, and FT-3) corresponding to three synthetic constitutional types (C 0-1, C 00, and C 01). These data indicate that the systemic (constitutional) approach to the estimation of individual typological characteristics confirm a high informativeness of partial constitution (FT-1, FT-2, and FT-3) in the human biological organization, and the set of characters selected for analysis allows the synthetic constitutional types to be adequately differentiated on a formal basis.     

Functional reserves and adaptive capacity of subjects with different levels of habitual physical activity

The basic characteristics of the cardiovascular system, physical capacity, and the degree of tension of regulatory mechanisms in the state of rest and under functional loading were identified on the basis of longitudinal studies in children of senior preschool and junior school ages, including boys and girls with low, medium, and high habitual physical activity (LHPA, MHPA, and HHPA). Analysis of the statistical distribution of traits using the χ² and λ tests and the average statistical data on various functional indicators in the total sample identified a fairly wide area and qualitative differences in physiological individuality in a healthy population and the advisability of distinguishing three typological groups, i.e., functional types (FT-1, LHPA; FT-2, MHPA; FT-3, HHPA). The typological parameters of the first and second orders for each FT and performance test parameters of the third order describing the current functional state have been distinguished. Determination of the physiological features of FT-1, FT-2, and FT-3 with the establishment of their functional reserves and adaptive capacity permits the identification of different strategies of interaction between the body and the environment, estimation of their advantages and disadvantages, and a more reasonable approach to optimization of physical condition and premorbid diagnosis.     

Health state,emotional intelligence,and behavior strategy: I. The development of emotional intelligence and the variability of behavior strategies in older preschool children with different levels of habitual physical activity

On the basis of the concept of the typological variability of human physiological individuality, we have determined the systemic correlation between the indicators of cognitive activity and the parameters and development of emotional intelligence (EI) and the formation of typical behavior strategies in older preschool children of three functional types (FT-1, FT-2, and FT-3), including subjects with low (LHPA), medium (MHPA), and high (HHPA) levels of habitual physical activity. We revealed the EI features typical of each functional group of children and observed a strong negative correlation between the indicator of HPA and the total EI score. The typical manifestation of EI is closely related to other psychological parameters of cognitive and emotional–volitional activity (logical and imaginative thinking, state anxiety, and attention), which allowed us to establish the constitutional features of the behavior strategy on the basis of the integrated assessment of all the obtained data. In different conflict situations, children with HHPA (FT-3) made decisions more rapidly and by themselves; their decisions were active and aimed at achieving a specific goal on the basis of domination (individual problem solving). In contrast, children with LHPA (FT-1) solved the problems on the basis of the emotional state of other people and preferred to explain the situation to their parents or educators and ask for help (cooperative problem solving). Up to 10% of children with LHPA preferred not to solve the problem.     

Chronobiological assessment of habitual physical activity in humans in Western Siberia

The concept of typological variability of physiological individuality was a methodological basis for chrono-physiological assessment of habitual physical activity (HPA) and heart rate (HR) in individuals with different functional types of constitution (FTC) (low HPA (FTC-1), medium HPA (FTC-2), and high HPA (FTC-3)) living at different latitudes of West Siberia (Tyumen, 57°09’N; Khanty–Mansi Autonomous Okrug (KhMAO)–Yugra, 61°00’N; and Yamal–Nenets Autonomous Okrug (YaNAO), 63°12’N). The typical chronostructure of the circadian rhythm of HPA and HR was established for each FTC under the conditions of both mid-latitude (Tyumen) and northern regions. The regional differences were determined too. Compared to the mid-latitude parameters, the chrono-physiological assessment of typological variability of HPA and HR in FTC-1, FTC-2 and FTC-3 subjects living under the climatic and geographical conditions of KhMAO–Yugra and YaNAO in each respective group demonstrated a decrease in the midline-estimating statistic of rhythm (MESOR) and energy intensity of the circadian rhythm, an increase in the proportion of ultradian rhythms, differences in the time of HPA and HR acrophases, a decrease in synchronization and coherence indices, as well as a higher coefficient of the number of heart beats per locomotion and a lower circadian index. All of the above parameters of northerners with each FTC, with regard for the general principles of modern approaches, are not pathologies but rather regional characteristics that should be taken into consideration in the assessment of general state of health and prenosological diagnostics; they were the basis for using chronoprevention and time correction of reduced physical activity.     

The concept of typological variability of physiological individuality: II. Somatotype heterogeneity of population groups differing in habitual physical activity

Individual typological characteristics of habitual physical activity (HPA) in subjects of the preschool, primary school, and young adult ages were determined, and three functional types (FTs) comprising subjects with low, medium, and high HPAs (LHPA, MHPA, and HHPA, respectively) were distinguished (FT-1, FT-2, and FT-3, respectively). Subsequent comparison between the three groups of subjects showed that they differed in the ratio between the numbers of subjects with different morphological types (somatotypes). The results are at variance with the generally accepted notion on unidirectional changes in functional characteristics in the eurysomy-leptosomy series and permit a conceptual approach to the development of a partial (functional) scheme of constitution.     

Functional reserves and adaptive potential of various levels of habitual motor activity

On the basis of longitudinal studies in children of older preschool and early school-age boys and girls with low, medium and high habitual physical activity (NAPA, SPDA, VPDA) identified the basic characteristics of the cardiovascular system, physical capacity and the degree of tension of regulatory mechanisms at rest and during functional loading. Analysis of the statistical distribution of the trait given chi2 and lambda criteria and average data of various functional indicators in the total sample identified a fairly wide area and the divergent levels of physiological individuality in a healthy population and the desirability of allocating the three typological groups--functional types (FT-1 - NAPA, the FT-2 - SPDA, FT-3 - VPDA). Model parameters are allocated first and second order for each CFT, as well as performance tests of the third order, describing the current functional status. Determination of the physiological features of the FT-1 FT-2 FT-3 with the establishment of their functional reserves and adaptive capacity makes it possible to identify the different strategies of interaction with the environment, evaluate their advantages and disadvantages and a more grounded approach to the problem of optimization of physical condition and prenosological diagnosis.     

The concept of typological variability of physiological individuality: III. Psychophysiological characteristics of functional types differing in habitual physical activity

Results of longitudinal studies were used to estimate the psychophysiological characteristics of preschool and young school children and young adults of both sexes belonging to functional types (FTs) with low, medium, and high habitual physical activity (HPA) levels (FT-1, LHPA; FT-2, MHPA, and FT-3, HHPA, respectively). Statistical analysis of the distributions of averaged psychophysiological parameters in the total sample with the use of the χ² and λ tests showed wide quantitative and qualitative ranges of psychophysiological individuality in a healthy population and demonstrated that it is reasonable to distinguish three typological groups (FT-1, FT-2, and FT-3). Typical first- and second-order parameters, as well as the results of third-order tests characterizing the current state, were determined for each FT. Determination of the psychophysiological characteristics of FT-1, FT-2, and FT-3 and their prevailing behavioral tendencies makes it possible to differentiate between strategies of organism-environment interaction and estimate their advantages and disadvantages.     

The concept of typological variability of physiological individuality: I. Intrapopulation diversity of human habitual physical activity and its typological estimation

A concept of typological variability of physiological individuality is suggested. In order to substantiate it, typological characteristics of individual variation in habitual physical activity (HPA) have been analyzed, at the first stage of the research, in subjects of both sexes at different ontogenetic stages (the preschool, primary school, adolescent, adult, and elderly ages). With the results of longitudinal studies taken into consideration, it has been demonstrated that HPA is a stable individual character in each age group and, in general, remains so in the course of ontogeny, as a subject changes age groups. This has made it possible to distinguish three functional types (FTs): subjects with low, medium, and high HPAs (FT-1, FT-2, and FT-3). An integrated approach to HPA assessment (pedometer measurements, daily electrocardiographic monitoring, a physical activity diary, and calculation of the circadian index) has allowed standards of daily physical activity and some functional characteristics of the cardiovascular system to be established in subjects of different FTs and prospects for further research in the assessment of individual health and the physiologically normal state to be determined on the basis of the new concept.     

Evidence for a hyporesponsive limbic-hypothalamic-pituitary-adrenal axis following early-life repetitive hypoglycemia in adult male rats

The developing limbic-hypothalamic-pituitary-adrenal (LHPA) axis is highly vulnerable to programming by early-life environmental factors, including exposure to synthetic glucocorticoids and nutrient deficiencies. Early-life repetitive hypoglycemia (RHG) is a common complication of insulin therapy for type-1 diabetes that may have long-term consequences in adulthood. Recent observations in a rat model of early RHG suggest persistent changes in LHPA axis function, including changes in relevant hormones and affective behaviors, which support a hyperresponsive LHPA axis. Thus, we hypothesized that early RHG would alter the expression of key genes regulating LHPA axis function in adulthood. The present study employed a rat model of insulin-induced RHG spanning postnatal days (P)24-28, a neurodevelopmental equivalent of early childhood in humans, to assess the long-term effects on mRNA levels for proteins relevant to the LHPA function and the corticosterone responses to ACTH stimulation of dispersed adrenocortical cells in vitro and restraint stress in vivo at adulthood. This early RHG model resulted in a hyporesponsive LHPA axis characterized by impaired corticosterone response, increased hippocampal glucocorticoid and mineralocorticoid receptor (GR and MR), decreased hypothalamic corticotropin-releasing hormone, increased adrenal steroidogenic-acute-regulatory protein and GR, and decreased adrenal MR, melanocortin-type-2 receptor and low-density lipoprotein receptor expression. Our findings highlight a complex environmental-gene interaction between RHG and LHPA axis during development that influences regulation of this axis in adulthood. The findings are consistent with the developmental origins of disease and underscore the influences of early-life events on the programming of a major regulatory system.

EEG and success in learning the job of autotransport driver in persons with different typologic characteristics of the nervous system

The properties of nervous processes: mobility and strength (capacity for work), were determined by the Khilchenko method in healthy subjects learning the trade of an automobile driver. People with different individual typological characteristics of higher nervous activity displayed significant differences in EEG energo-frequency parameters of different brain areas. It has been shown that EEG of practically healthy people at rest, in conjunction with other informative psycho-physiological data, offers promise for appraising the individual typological characteristics of a person in predicting the professional suitability for driving automobiles.     

Therapeutic indications for delayed puberty and hypogonadism in adolescent boys.

Testosterone and synthetic androgens have formerly been used indiscriminately, but are now applied more selectively. They are the only treatment of primary hypogonadism, but are also useful in gonadotropin deficiency and constitutional delay. 17-Alkylated androgens are no longer used. Oral testosterone undecanoate is not suitable for adolescents because of unreliable absorption. The prototype disorder where replacement is necessary is congenital anorchia. As a physiological replacement, an initial dose of 35 mg/m2 per month for 6 months, followed by 70 mg/m2 for 1 year, and 150 mg/m2 thereafter, is recommended. No general rules can be given for other types of primary hypogonadism. In testicular atrophy after cryptorchidism, defects of testosterone biosynthesis, galactosemia or other causes, it is advisable to carry out periodic testosterone determinations and to wait until the levels drop below normal. Progress has been made in the treatment of gonadotropin deficiency, and pulsatile gonadotropin-releasing hormone (GnRH) has been shown to be effective in the hypothalamic type. Nevertheless, androgens still have a temporary place in this condition. In constitutional delay of growth and adolescence, treatment is not necessary somatically, but there are often psychosocial reasons. Gonadotropins, GnRH or growth hormone (GH)-releasing hormone have been used. Also treatment with human GH is successful in accelerating height velocity. The most simple and economic treatment is still testosterone in a physiological dose for 3-6 months. Oxandrolone or other synthetic androgens have no advantages.     

A proteomic approach to analysing spheroid formation of two human thyroid cell lines cultured on a random positioning machine

The human cell lines FTC-133 and CGTH W-1, both derived from patients with thyroid cancer, assemble to form different types of spheroids when cultured on a random positioning machine. In order to obtain a possible explanation for their distinguishable aggregation behaviour under equal culturing conditions, we evaluated a proteomic analysis emphasising cytoskeletal and membrane-associated proteins. For this analysis, we treated the cells by ultrasound, which freed up some of the proteins into the supernatant but left some attached to the cell fragments. Both types of proteins were further separated by free-flow IEF and SDS gel electrophoresis until their identity was determined by MS. The MS data revealed differences between the two cell lines with regard to various structural proteins such as vimentin, tubulins and actin. Interestingly, integrin α-5 chains, myosin-10 and filamin B were only found in FTC-133 cells, while collagen was only detected in CGTH W-1 cells. These analyses suggest that FTC-133 cells express surface proteins that bind fibronectin, strengthening the three-dimensional cell cohesion.     

The tumor suppressor PTEN inhibits EGF-induced TSP-1 and TIMP-1 expression in FTC-133 thyroid carcinoma cells

Thrombospondin-1 (TSP-1) is a multidomain extracellular macromolecule that was first identified as natural modulator of angiogenesis and tumor growth. In the present study, we found that epidermal growth factor (EGF) up-regulated TSP-1 expression in FTC-133 (primary tumor) but not in FTC-238 (lung metastasis) thyroid cancer cells. Both EGF and TSP-1 induced expression of tissue inhibitor of metalloproteinase-1 (TIMP-1) in a mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) and phosphatidylinositol 3-kinase (PI3-kinase)-dependent manner. In FTC-133 cells, EGF induced proliferation in a TSP-1- and TIMP-1-dependent manner. In addition, we determined that re-expression of the tumor suppressor protein PTEN induced cell death, an effect that correlated with a block of Akt kinase phosphorylation. EGF-induced TSP-1 and TIMP-1 promoter activity and protein expression were inhibited in FTC-133 cells stably expressing wtPTEN but not in cells expressing mutant PTEN. Furthermore, we found that wtPTEN inhibited EGF--but not TSP-1--stimulated FTC-133 cell migration and also inhibited invasion induced by EGF and by TSP-1. Finally, an antibody against TSP-1 reversed EGF-stimulated FTC-133 cell invasion as well as the constitutive invasive potential of FTC-238 cells. Overall, our results suggest that PTEN can function as an important modulator of extracellular matrix proteins in thyroid cancer. Therefore, analyzing differential regulation of TSP-1 by growth factors such as EGF can be helpful in understanding thyroid cancer development.     

On theoretical principles of constitution typology

Constitution typology is thought of as a classification that is based on a few fundamental properties of the organism. These properties steadily distinguish individuals and permit the prediction of manifold secondary (external) features of types. At the transition from one constitutional type to another, concordant changes of trait values are determined by the respective changes of general causal factors. Theoretically, external constitution typology should be constructed on the basis of trait concordant "dynamics" under the change of fundamental factors at the individual level. Therefore, it does not depend on statistical relations characterizing population level. Causal factors and their influences on traits are impossible to be correctly and uniquely determined on the basis of population statistics relations. Causal factors do not coincide with the statistical ones of multivariate biometric analysis; equally, trait regression dependencies on statistical factors do not coincide with the causal influences.     

The Multifactor Study of Certain Individual Typological Features of Man and Their Relation to Differences in Nervous-System Strength

Contemporary psychological and physiological studies on the typological features of behavior are more and more often concerned with problems whose resolution requires a synthetic approach to the way in which the problem is posed and to methods for studying it.     

Functional properties of the apical Na+-K+-2Cl- cotransporter isoforms.

The bumetanide-sensitive Na(+):K(+):2Cl(-) cotransporter (BSC1) is the major pathway for salt reabsorption in the apical membrane of the mammalian thick ascending limb of Henle. Three isoforms of the cotransporter, known as A, B, and F, exhibit axial expression along the thick ascending limb. We report here a functional comparison of the three isoforms from mouse kidney. When expressed in Xenopus oocytes the mBSC1-A isoform showed higher capacity of transport, with no difference in the amount of surface expression. Kinetic characterization revealed divergent affinities for the three cotransported ions. The observed EC(50) values for Na(+), K(+), and Cl(-) were 5.0 +/- 3.9, 0.96 +/- 0.16, and 22.2 +/- 4.8 mm for mBSC1-A; 3.0 +/- 0.6, 0.76 +/- 0.07, and 11.6 +/- 0.7 mm for mBSC1-B; and 20.6 +/- 7.2, 1.54 +/- 0.16, and 29.2 +/- 2.1 mm for mBSC1-F, respectively. Bumetanide sensitivity was higher in mBSC1-B compared with the mBSC1-A and mBSC1-F isoforms. All three transporters were partially inhibited by hypotonicity but to different extents. The cell swelling-induced inhibition profile was mBSC1-F > mBSC1-B > mBSC1-A. The function of the Na(+):K(+):2Cl(-) cotransporter was not affected by extracellular pH or by the addition of metolazone, 4,4'-diisothiocyanatostilbene-2,2'-disulfonic acid (DIDS), or R(+)-[(2-n-butyl-6,7-dichloro-2-cyclopentyl-2,3-dihydro-1-oxo-1-H-indenyl-5-yl)-oxy]acetic acid (DIOA) to the extracellular medium. In contrast, exposure of oocytes to HgCl(2) before the uptake period reduced the activity of the cotransporter. The effect of HgCl(2) was dose-dependent, and mBSC1-A and mBSC1-B exhibited higher affinity than mBSC1-F. Overall, the functional comparison of the murine apical renal-specific Na(+):K(+):2Cl(-) cotransporter isoforms A, B, and F reveals important functional, pharmacological, and kinetic differences, with both physiological and structural implications.     

Typology of the nervous system and personality

The paper deals with structural organization of psycho-physiological and psychological characteristics of personality. The following characteristics were estimated: psychomotor, intellectual, creative abilities, features of imagination as well as basic properties of personality: extraversion--introversion, and neuroticism. Using the Q-technique of factor analysis of the 1-st, 2-nd and 3rd orders, the authors singled out three types of psychophysiological and psychological human organization. Each type was given a generalized interpretation. Conclusion is made that these types reflect more generalized processes than factors derived with R-technique of factor analysis.
