Sexual dimorphism in relationships between of plasma urea and some psycho-neuro-endocrine parameters

Background. Earlier we found a strong urato-neural relationships in both men and women. Moreover, in women, the factor structure of the neural root is almost completely different from that in men. In addition, significant differences were found between the profiles of urato-neural correlations of women of reproductive age and postmenopausal women. The purpose of this study is to analyze the relationships between the plasma urea level and some psycho-neuro-endocrine parameters in the same cohort. Materials and Methods. The object of observation were almost healthy volunteers: 31 males (24÷69 y) and 30 females, from among them 18 postmenopausal (48÷76 y) and 12 of reproductive age (30÷45 y). In basal conditions we determined plasma levels of urea and adaptation hormones, estimated the severity of the trait and reactive anxiety, recorded the ongoing HRV and EEG. After 4 or 7 days, repeated testing was performed. Results. By building regression models with stepwise exclusion, it was found that in men plasma urea positively determines (R2=0,499) the level of circulating catecholamines and power spectrum density (PSD) of δ-, θ- and β-rhythms in different loci. In postmenopausal women, urea downregulates the amplitude and PSD of δ-rhythm in different loci, instead, it upregulates the PSD of α-rhythm in T5 locus, entropy of EEG in 2 loci and vagal tone. The degree of determination of neural parameters is 71,6%. In women of reproductive age the degree of determination of neural parameters is similar (69,9%), but the factor structure of the model is completely different. Urea upregulates the PSD of β-rhythm in F7 locus while downregulates the levels of reactive anxiety, vagal tone, entropy of EEG in 3 loci and P4-θ PSD as well as causes left lateralization of θ- and α-rhythms. Conclusion. Plasma urea has a modulating effect on EEG&HRV parameters, as well as reactive anxiety, but this effect is significantly different in men and women of different ages

Sexual dimorphism in relationships between of plasma creatinine and some neuro-endocrine parameters

Background. Earlier we found that plasma uric acid and urea causes modulating effects on neuro-endocrine parameters, as well as reactive anxiety, but these effects are significantly different in men and women of different ages. The purpose of this study is to analyze the relationships between the plasma creatinine level and some psycho-neuro-endocrine parameters in the same cohort. Materials and Methods. The object of observation were almost healthy volunteers: 31 males (24÷69 y) and 30 females, from among them 18 postmenopausal (48÷76 y) and 12 of reproductive age (30÷45 y). In basal conditions we determined plasma levels of creatinine and adaptation hormones, estimated the severity of the trait and reactive anxiety, recorded the ongoing HRV and EEG. After 4 or 7 days, repeated testing was performed. Results. By building regression models with stepwise exclusion, it was found that in men plasma creatinine downregulates the level of Cortisol (r=-0,41) while upregulates the levels of Testosterone (r=0,36) and Calcitonin (r=0,30). The degree of determination of endocrine parameters is 31,9%. In postmenopausal women, creatinine also upregulates Testosterone (r=0,43) while downregulates the amplitude and PSD of β-rhythm in different loci as well as causes right lateralization of β-rhythm. The degree of determination of neuro-endocrine parameters is 61,2%. In women of reproductive age creatinine upregulates the PSD of ULF band HRV and α-rhythm in 5 loci as well as the Entropy of EEG in F3 locus while downregulates the Entropy in T6 locus, F3-δ and T6-θ PSD as well as Cortisol level. The degree of determination of neuro-endocrine parameters is 94,0%. Conclusion. Plasma creatinine has a modulating effect on neuro-endocrine parameters, but this effect is significantly different in men and women of different ages

Sexual dimophism in plasma nitrogenous metabolites levels and some psycho-neuro-endocrine parameters

Background. We previously showed that the factor structure of the relationships between the plasma levels of nitrogenous metabolites (uric acid, bilirubin, urea, and creatinine), on the one hand, and the parameters of anxiety and neuro-endocrine status, on the other hand, is significantly different in men and women of reproductive age and postmenopausal. The purpose of this study is to identify the metabolic and psycho-neuro-endocrine features of these three cohorts of people. Materials and methods. The object of observation were 31 males (24÷69 y) and 30 females, from among them 18 postmenopausal (45÷76 y) and 12 of reproductive age (30÷42 y), with dysfunction of neuro-endocrine-immune complex. In basal conditions we determined plasma levels of nitrogenous metabolites and adaptation hormones, estimated the severity of the trait and reactive anxiety, recorded the ongoing HRV and EEG. After 4 or 7 days, repeated testing was performed. Results. To achieve the goal, the registered parameters were subjected to discriminant analysis. Along with the quite expected nitrogenous metabolites, age, testosterone and calcitonin (both raw and sex- and age-standardized values), trait anxiety, Kerdö's Vegetative Index, one of the vagal markers (SDNN), as well as 10 EEG parameters emerged as characteristic features of the cohorts. In the information space of two discriminant roots, three cohorts are clearly demarcated. Conclusion. We interpret this as another proof of the existence of connections between nitrogenous metabolites and psycho-neuro-endocrine parameters in line with the concept of the functional-metabolic continuum

Phenomenology of health

Health, as a phenomenon of a planetary scale, reflects the life of mankind, the world of animals and plants. Human health issues from the mid-20th century began to come out of the exclusive medical control. The increase in the average life expectancy of the population of developed countries, the globalization of economic, political, cultural life, the emergence of pandemics of viral infections - all these factors have shown that in maintaining the health of the population, the actual medical contribution is no more than 10%. The rest of the influence is exerted by economic, environmental, social and hereditary factors. The burden of disease of the population causes significant damage to the economies of even the most developed countries. Human health is a comprehensive, integrative assessment of the quality of his being for each specific time and age period. Thus, we consider health as a derivative of the ontogenetic scale. A feature of this scale is the unification on the time axis (x) of both calendar and biological ages. The axis (y) reflects the magnitudes of the influence of known determinants of health that accompany a person at each stage of his ontogenetic movement. One of the most important conditions for the functioning of the human body and animals is the constancy of the internal environment, defined as homeostasis. It is thanks to homeostasis that every cell of the body is in a relatively constant environment, which is an extracellular fluid. Earlier we drew attention to the fact that all the parameters of extracellular fluid can be divided into indicators of water-salt homeostasis (osmolality, concentrations of ions Na, K, Ca, pH). The task of water-salt homeostasis is to ensure water balance, both intracellular water content and the total amount in the body. The second group of homeostasis indicators is represented by metabolites (glucose, lipids, amino acids, proteins, urea, creatinine, bilirubin, etc.). On the one hand, metabolic indicators are quite stable, which made it possible to attribute them to homeostasis, but on the other hand, their most important feature is that they are very closely related to the functional state of the body (organs, tissues, cells), since the main task of metabolism is to adequately provide the organs and tissues of functioning systems with the necessary amount of energy and plastic substrates. Accordingly, with changing functions, the levels of the main metabolites should also change. At the same time, the main criterion for the adequacy of the metabolic support of functioning systems is not their homeostating concentration, but compliance with the changing needs of organs and tissues. That is, in the body it is necessary to ensure a sufficiently strong relationship between function and metabolism. In the literature, the subjective assessment of whether social factors affecting health can be avoided through structural changes in policy and practice appears to be the dominant way to determine the social determinant of health. In addition, the term "social" remains ambiguous and difficult to define within the clear boundaries of health care. There are already concerns about the requirements and approaches to their screening, as well as their benefits and unintended harm. A long list of CLE can prevent doctors from prioritizing screening for social determinants and referring patients to support services. Politicians may also be less inclined to continue working with such a long and growing list. In most government agencies, there are inherent barriers to adopting a social determinant approach in policymaking. A long list can add additional restrictions on adoption. A clear understanding of the "social determinants of health" is critical for all key stakeholders, including the public

Relationships between geomagnetic Ар-indeх and EEG parameters in patients with dysfunction of the neuroendocrine-immune complex

Background. Recently, on the example of two cohort of patients, we found that disturbances of the geomagnetic field cause a significant immediate modulating effect on the level of immune parameters in the blood. The data available in the literature give grounds for assumptions about the direct effect of disturbances of the geomagnetic field on immunocytes, and indirectly, through immunotropic neurotransmitters and hormones. Our hypothesis is as follows. Disturbances of the geomagnetic field are perceived by acupuncture points (APs). The information obtained is transmitted to neurons and endocrinocytes, the mediators of which, in turn, affect immunocytes. The purpose of this study is to test this hypothesis. Methods. The object of observation were 21 men (24-63 y) and 20 women (30-72 y) with neuroendocrine-immune complex dysfunction. Each patient was tested twice with an interval of 4 days. We recorded the ongoing electroencephalogram (EEG). Retrospectively we recorded the geomagnetic Ap-Index on the day of testing and during the previous 7 days, using resource https://www.spaceweatherlive.com/. Results. The canonical correlation between Ap-indices for 7 days before and on the day of testing, and EEG parameters is 0,886; immunity parameters is 0,921. In turn, the immune parameters are closely related to the EEG parameters (R=0,944). Conclusion. Disturbances of the geomagnetic field (Ap-index) causes a significant immediate modulating effect on the parameters of immunity as well as EEG, apparently through acupuncture points as polymodal receptors of the ecoceptive sensitivity system

Sexual dimorphism in relationships between of plasma bilirubin and some neuro-endocrine parameters

Background. Earlier we found that plasma uric acid, urea and creatinine causes modulating effects on neuro-endocrine parameters, as well as anxiety, but these effects are significantly different in men and women of different ages. The purpose of this study is to analyze the relationships between the plasma bilirubin level and some psycho-neuro-endocrine parameters in the same cohort. Materials and Methods. The object of observation were almost healthy volunteers: 31 males (24÷69 y) and 30 females, from among them 18 postmenopausal (48÷76 y) and 12 of reproductive age (30÷45 y). In basal conditions we determined plasma levels of bilirubin and adaptation hormones, estimated the severity of the trait and reactive anxiety, recorded the ongoing HRV and EEG. After 4 or 7 days, repeated testing was performed. Results. By building regression models with stepwise exclusion, it was found that in men plasma bilirubin upregulates the variability of β- and α-rhythms as well as PSD of β-rhythm in T4 and Fp2 loci, but downregulates the variability of θ-rhythm, PSD of β-rhythm in P4 and δ-rhythm in T6 loci as well as the trait anxiety. The measure of determination is 42,6% In postmenopausal women, bilirubin downregulates the PSD of β-rhythm in T6 locus, but upregulates the Testosterone plasma level, vagal tone as well as PSD of ULF and VLF bands HRV. The degree of determination of neuro-endocrine parameters is 59,2%. In women of reproductive age bilirubin upregulates the PSD of β-rhythm in T4 locus while downregulates the amplitude of θ- and β-rhythms, PSD of β-rhythm in 5 loci, of α-rhythm in 5 other loci as well as the Entropy of EEG in T5, P4 and C4 loci. The degree of determination of EEGs parameters is 97,8%. Conclusion. Plasma bilirubin has a modulating effect on psycho-neuro-endocrine parameters, but this effect is significantly different in men and women of different ages, which is due, apparently, to the influence of sex hormones on the expression of Ah receptors in neurons

Relationships between geomagnetic Ар-indeх and HRV and endocrine parameters in patients with dysfunction of the neuroendocrine-immune complex

Background. Recently, on the example of two cohort of patients, we found that disturbances of the geomagnetic field cause a significant immediate modulating effect on the level of immune parameters in the blood. The data available in the literature give grounds for assumptions about the direct effect of disturbances of the geomagnetic field on immunocytes, and indirectly, through immunotropic neurotransmitters and hormones. Our hypothesis is as follows. Disturbances of the geomagnetic field are perceived by acupuncture points. The information obtained is transmitted to neurons and endocrinocytes, the mediators of which, in turn, affect immunocytes. The purpose of this study is to test this hypothesis. Material and methods. The object of observation were 21 men (24-63 y) and 20 women (30-72 y) with neuroendocrine-immune complex dysfunction. Each patient was tested twice with an interval of 4 days. Retrospectively we recorded the geomagnetic Ap-Index on the day of testing and during the previous 7 days, using resource https://www.spaceweatherlive.com/. Recorded the heart rate variability (HRV) parameters, determined the plasma level of cortisol, triiodothyronine and testosterone. Results. During the week, the average level of Ap-index ranged from 7 to 13 nT. Maximum coefficients of multiple correlation with HRV&Hormonal parameters were detected for Ap-index on 2 (R=0,506) and 7 (R=0,403) days before testing. The canonical correlation between Ap-indices for 7 days before and on the day of testing, and the HRV&Hormonal parameters is 0,766. In turn, the immune parameters are closely related to the HRV&Hormonal parameters (R=0,714). Conclusion. Disturbances of the geomagnetic field (Ap-index) causes a significant immediate modulating effect on the immune, HRV and endocrine parameters, apparently through acupuncture points as polymodal receptors of the ecoceptive sensitivity system

Relationships between geomagnetic Ар-indeх and parameters of the acupuncture points as well as neuroendocrine-immune complex in patients with its dysfunction

Background. Back in 1990, YuP Limansky hypothesized acupuncture points (AP) as polymodal receptors of the ecoceptive sensitivity system. In the process of hypothesis development in 2003 an existence of separate functional system of regulation of electromagnetic balance of organism has been substantiated and a working conception of light therapy has been formulated. In line with this hypothesis, we set out to analyze the relationships between the disturbances of the geomagnetic field (Ap-index) and the electrical conductivity of a number of AP, on the one hand, and the parameters of the neuroendocrine-immune complex in patients with its dysfunction, on the other. Material and methods. The object of observation were 21 men (24-63 y) and 20 women (30-72 y) with neuroendocrine-immune complex dysfunction. Each patient was tested twice with an interval of 4 days. Retrospectively we recorded the geomagnetic Ap-Index on the day of testing and during the previous 7 days, using resource https://www.spaceweatherlive.com/. Recorded the electrical conductivity of 9 pairs of AP, electroencephalogram (EEG) and heart rate variability (HRV) parameters, determined the plasma level of cortisol, triiodothyronine and testosterone, the content of lymphocytes expressing CD3, CD4, CD25, CD8, CD22 and CD56 receptors, the serum level of circulating immune complexes, immunoglobulins classes M, G, A as well as C-reactive protein, IL-1β and IL-6. The state of phagocytic function of neutrophils estimated by microbial count and phagocytic and killing indices against Staphylococcus aureus and Escherichia coli. Results. During the week, the average level of Ap-index ranged from 7 to 13 nT. Maximum coefficients of multiple correlation with APs parameters were detected for Ap-index on 6 day before (R=0,552) and on the day of testing (R=0,470), with EEG parameters on the eve of registration (R=0,708) and on 6 day before its (R=0,685), with immunity parameters on the eve of blood sampling (R=0,768) and on 5 day before its (R=0,758), with HRV&Hormonal parameters on 2 (R=0,506) and 7 (R=0,403) days before testing. The canonical correlation between Ap-indices for 7 days before and on the day of testing, and the parameters APs is 0,661; EEG parameters is 0,886; HRV&Hormonal parameters is 0,766 and immunity parameters is 0,921. APs parameter are closely related to the EEG (R=0,997) and HRV&Hormonal parameters (R=0,740). In turn, the immune parameters are closely related to the EEG (R=0,944) and HRV&Hormonal parameters (R=0,714). Conclusion. Disturbances of the geomagnetic field (Ap-index) causes a significant immediate modulating effect on the parameters of neuroendocrine-immune complex, apparently through acupuncture points as polymodal receptors of the ecoceptive sensitivity system

Resistance of some rice varieties to species hydrellia griseola fall.(Diptera, Ephydridae)

At three regions in Macedonia(Kocani, Shtip and Vinica-Blatec), during 1998 and 1999 the resistance of eight rice varieties (Monticelli, Biser-2, San Andrea, Argo, Loto, Drago, Koral and Cripto) to species Hydrellia griseola Fall, was investigated. The bigest damage to investigated varieties at investigated locality in the Shtip region and during 1998 was concluded. Varieties Koral and Biser-2 are classified as the resistant ones and the most sensitive varieties were Cripto and Loto during the investigated period
