THE WORKS OF SPIRIDON MIKHAILOV (YANDUSH) IN THE ASPECT OF SOME HISTORICAL ETHNOLOGY PROBLEMS

S.M. Mikhailov (Yandush) distinguished two ethnographic groups and two dialects of the Chuvash ethnos. The scientist attributed the population of Kozmodemyansky and the northern part of Yadrinsky uyezds to the upper (Virjal) Chuvash, and that of Tsivisky and Cheboksary uyezds of Kazan province – to the lower (Anatri) ones. Starting with the works of G.I. Komissarov, a third (middle-level) group began to be allocated from the lower group. According to the scientist, the Chuvash, being a separate community of Turkic-speaking peoples, used to live in Zakamye, where they had migrated from Siberia. He developed the Turkic-Bulgarian theory of the Chuvash language origin and the main ethnographic groups (middle lower and lower) of the Chuvash ethnos. He considered the upper dialect to be a mixed group, in whose culture, in addition to Turkic-Bulgar elements he found many elements of the Finno-Ugrians (the mountain Mari and the Mordvins-Erzya), and partly Kazan Tatars. Prior to annexation of the Chuvash Region to the Moscow state, two ethnographic groups of the mountain Chuvash functioned on the right bank of the Volga – the upper and the middle lower. After settling the southern steppe regions, in the process of cultural dialogue with the Mishar Tatars, a third ethnographic group was formed, known to the middle lower Chuvash as the khirti “steppe”. In Modern times, the geographical location of the ethnographic groups of the Chuvash ethnos contributed to penetration of the ideas of the European-Russian Enlightenment in the Chuvash Region (from the western territories to the eastern and southern ones). In the 1950s of the XX century the ideas of the Chuvash enlightenment were first formulated by S.M. Mikhailov, and later they began to spread in the academic circles of the entire Volga region. His works remain a valuable source for identifying the adaptive scheme of the ethnos, which the Chuvash built by localizing the “evil” principle outside of themselves, their society, ethnos.

Lower Masticatory Performance Is a Risk for the Development of the Metabolic Syndrome: The Suita Study

Objectives: Declined masticatory function has recently been receiving attention as a risk factor for poor general health. The present longitudinal analysis was conducted to clarify the relationship between decreased masticatory performance and the development of the metabolic syndrome (MetS) in a general urban cohort in Japan.Methods: We surveyed 599 participants (254 men, 345 women; mean age at baseline, 65.8 ± 7.8 years) who underwent physical health checkups in the Suita study. We evaluated masticatory performance at baseline using test gummy jelly and divided participants into two groups: a “Lower group,” comprising participants in the lower 25% of the masticatory performance at baseline; and a “Normal group,” comprising all others. We estimated hazard ratios (HRs) for the Lower group by using Cox proportional hazard regression analysis to develop the MetS and the components of the MetS at follow-up, adjusting for age, smoking status, and periodontal status.Results: On Cox proportional hazard regression analysis, the multivariable adjusted hazard ratio for the development of the MetS in the Lower group was 2.24 (95% confidence interval, 1.12–4.50) in men. The multivariable adjusted hazard ratio for the development of high blood pressure was 3.12 (1.42–6.87), for high triglycerides was 2.82 (1.18–6.76), and for high fasting plasma glucose was 2.65 (1.00–7.00) in men.Conclusions: Lower masticatory performance suggested to be a risk factor for the development of the MetS as well as MetS components such as high blood pressure, high triglycerides, and high fasting plasma glucose in Japanese men.

Analysis of Environmental Management Characteristics Using Network Analysis of CEO Communication in the Automotive Industry

CEO messages in CEO communication are becoming increasingly important. From a sustainable management perspective, it is imperative to study environmental, social, and governance messages. Previous studies on CEO messages have focused on financial analyses. In contrast, this study (1) extracted environment-related words in the CEO messages of automotive companies, (2) selected high- and low-performing automotive manufacturers based on car sales data, (3) compared environment-related keywords used by high-performing (upper group) and low-performing (lower group) companies, and (4) performed a structural interpretation of the keywords to analyze the characteristics of environmental management. A comparison between the upper and lower groups revealed that six keywords—society, electric, technology, standards, contribute, and global—were exclusive to the upper group. The six keywords exclusive to the lower group were sales, target, promote, energy, efforts, and system. Environmental keywords and eco-innovation factors were subjected to keyword–factor mapping and network analysis. Normative pressures, technology, and environmental managerial concerns were the key factors with the highest centrality. Accordingly, the environmental management characteristics of the upper-group corporations can be used as benchmarks by lower groups.

Encapsulation of bacteriophage cocktail into chitosan for the treatment of bacterial diarrhea

The therapeutic effectiveness of a chitosan encapsulated bacteriophage cocktail as a smart biocontrol agent was evaluated in this study to be used as a preventative and treatment option for gastrointestinal infections. To evaluate the effect of the bacteriophage formulation on the treatment of gastrointestinal infection, rats were infected with Salmonella enterica, Shigella flexneri, and Escherichia coli. The rats were weighed and their stools cultured. The results showed that the group which had the chitosan encapsulated bacteriophage cocktail did not lose weight after 3 days and had significantly lower group weight changes. Weight loss was significant in the rats that had cefixime administered instead. Positive cultured stools were reduced after 4 days compared to 2 days in the treated group with the chitosan encapsulated bacteriophage cocktail. The chitosan encapsulated bacteriophage cocktail can therefore be effective in the treatment of gastrointestinal infections.

Effect of Dopamine, a Human Love Factor, on the Physio-Chemical Properties of Filamentous Green Alga: Spirogyra

Dopamine is a hormone & neurotransmitter, occurring in wide verities of animals, including both vertebrates and invertebrates. In chemical structure, it is a phenylethylamine. Dopamine is commonly associated with the pleasure system of the brain, providing the feelings of enjoyment and reinforcement to motivate a process to perform certain activities. It is released (particularly in area such as nucleus accbens and ventral tegmental area) by naturally rewarding experiences such as food sex etc. Since conjugating is such type of activity i.e. it is also manifested in lower group of filamentous algae, it was thought that how these groups of algae respond to dopamine. The effect of dopamine was studied on the physico-chemical properties of Spirogyra and it was observed that the changing the colour to yellow is accomplished by the formation of new compounds (??) needs further investigation.

Association between healthy lifestyle practices and life purpose among a highly health-literate cohort: a cross-sectional study

Background The national health promotion program in 21st century in Japan (HJ21) correlates life purpose with disease prevention; facilitating the adoption of healthy lifestyles. However, the influence of clustered healthy lifestyle practices on life purpose, in the context of a national health campaign, remains uninvestigated. Hence, this study assessed the association between such practices and life purpose in line with the HJ21. Methods A nationwide cross-sectional survey was given to certified specialists in health management. Participants’ demographic information, lifestyle, and purpose in life using a validated tool were measured. The cohort was median-split into two groups based on their clustered health-related lifestyle score. Health-related lifestyle and purpose were compared between the two groups, and the correlation between health-related lifestyles and purpose in life was measured. Results Data from 4,820 participants were analyzed. The higher scoring health-related lifestyle group showed a significantly higher life purpose than the lower group (35.3 vs 31.4; t = 23.6, p < 0.001). The association between the scores of clustered healthy lifestyle practices and life purpose was significant (r = 0.401, p < 0.001). The better health-related lifestyle group achieved a higher life purpose than the lower group. This association between healthy lifestyle practices and life purpose denotes a positive and linear relationship. Conclusions The present study suggest that individuals who have a better health-related lifestyle gain a higher sense of life purpose. Healthy lifestyle predicted purpose in life. Examining causal relation between healthy lifestyle and purpose in life may provide more efficient approach for health promotion.

Elevated Serum Chloride Level Contributes to the Poor Prognosis of IgA Nephropathy

IntroductionFinding reliable prognostic factors is crucial for IgA nephropathy (IgAN). Here, we determined the relationship between prognosis of IgAN with serum chloride.MethodsPrimary IgAN diagnosed by renal biopsy from January 1, 2015 to April 1, 2019 were recruited. Patients were divided into lower group and higher group based on the best cut-off value of survival receiver operating characteristics (ROC) curves. The baseline clinicopathological characteristics were retrospectively compared. Cox proportional hazard models were used to demonstrate the prognostic value of serum chloride in IgAN. Prognosis prediction model was built by multivariate Cox regression. ResultsCompared to higher group , age、24-hour urinary protein and serum creatinine(Cr) in the lower group were significantly lower, hemoglobin(Hb)、albumin were significantly higher(all P<0.05),the degree of endothelial cell proliferation (E) and renal tubule atrophy or renal interstitial fibrosis (T) were significantly lighter (all P<0.05). Univariate and multivariate Cox analysis revealed that serum chloride ≥105.4 mmol/l was an independent risk factor for the prognosis of IgAN(P<0.05). Serum chloride, Cr, T, hypertension, and Hb were screened out as features in predictive prognosis model. The c-index of the model was 0.85、0.82 and 0.77 for 1、2 and 3 years respectively, and brier scores were 0.06 、0.09 and 0.16 respectively. ConclusionsSerum chloride ≥105.4 mmol/l was an independent risk factor for the prognosis of IgAN. A predictive prognosis model including serum chloride, Cr, T, hypertension and Hb exhibited a relatively good prediction effect.

Bioavailability and toxicity variation of benzo[a]pyrene in three soil-wheat systems: Indicators of soil quality

Benzo[a]pyrene (B[a]P) as a representative polycyclic aromatic hydrocarbons is concerned by global scientists in various fields, but its biological and biochemical actions in soil-wheat systems are still rarely reported. The B[a]P as a ubiquitous soil pollutant possesses varied contents in real environment, and herein was studied in systems of soil and wheat to obtain relative results to reveal their variations in different systems. Its bioavailability (extractability and bioaccumulation) and basic biological toxicity were tested based on three typical soil types (red, black, and brown) in China and spiked amounts (0.1, 1, and 10 mg/kg) with several orders of magnitude. Results showed that B[a]P concentrations in soil-wheat systems extracted by HPCD were insignificantly (p > 0.05) higher than Tenax-TA, and varied with soil types and spiked concentrations. Besides, the root and shoot length were mostly inhibited, in a range of -21.85%-26.35% and -0.48%-54.85%, respectively, by B[a]P in different soil types and increased with its increasing concentration. Comparatively, higher bioconcentration factor and translocation factor values were observed under lower group in red soil-wheat systems, and higher spiked groups in black and brown soil-wheat systems. Moreover, inhibitive effects posed by B[a]P were mainly targeted at wheat shoots in these soils. The simultaneous studies provided a comparable knowledge of B[a]P in ecosystems of different soil types combined with different plant species due to lots of variations, further to serve for contaminated soil remediation and sustainable agricultural management.
