Clinical and laboratory investigation of violations of lipid and carbohydrate metabolism in children consuming drinking water of non-normative quality on content of organochlorine compounds. Children with elevated blood concentrations of chloroform and carbon tetrachloride, endocrine pathology are diagnosed 2.1 times more likely, the relative risk of developing obesity (E66.0) and excess supply (E67.8) is by 2.7 times higher than in the comparison group. There was found a causal relationship between the development of overweight children with a high content of chloroform in blood. Negative effects of organochlorines (chloroform, carbon tetrachloride) manifested by dysfunction of the hypothalamic-adrenal and pituitary-thyroid system, the activation offree radical oxidation and the accumulation ofperoxidation products, overvoltage and resource depletion of antioxidant defense, and violation of neurotransmitter processes was found to be followed by dysregulation offat and carbohydrate exchange. There were identified markers of disorders of lipid and carbohydrate metabolism in the conditions of exposure to chloroform and carbon tetrachloride.

Introduction. The authors performed a hygienic and epidemiological study of the Perm Territory areas with unfavorable sanitary and hygienic indices. Material and methods. The study involved 7,775 children aged from 4 to 14 years (9.2 ± 3.7 years) living in territories using sodium hypochlorite or liquid chlorine (Perm, Krasnokamsky, Nytvensky districts). The comparison group consisted of 425 children (average age 9.3 ± 2.5 years) consuming drinking water that complies with hygienic standards (Sivinsky, Karagai districts). Results. Identified areas with low quality of drinking water supply due to the content of organochlorine compounds (OCS) appeared to have an increased prevalence of obesity, diabetes, ischemic, and hypertensive disease. The authors developed and tested the critical assessment of the risk of formation disorders of fat and carbohydrate metabolism in children consuming drinking water with a high content of organochlorine compounds. Under conditions of oral exposure to OCS (0.43-0.64 mg / l, more than 3 MPC), the index of the risk of impaired fat and carbohydrate metabolism in children (IPI 0.55) was 1.3 times higher than the corresponding levels in the territory of comparison (IPI 0,42). Conclusion. The main markers for the indices of the negative impact of HOS (primarily chloroform) include an increase in the blood level of triglycerides (PS 0.41), LDL (PS 0.25) and a decrease in HDL (PS 0.18), exceeding 1, 2-1.6 times the territory of comparison.

Universal Mechanism

The effect of increased UV-A radiation during the ontogeny of barley plants of the Vladimir variety in the vegetation experiment was studied. Changes in the content of malonic dialdehyde, flavonoids and grain yield were revealed. UV-A radiation as compared to UV-B radiation, has lower quantum energy and can have both positive and negative effects on plant regulatory and photosynthetic processes. One of the most damaging effects of increased levels of UV-A radiation is oxidative stress, which causes lipid peroxidation of biological membranes. The existence of a plant cell in such conditions is possible only thanks to a system of antioxidant defense mechanisms. The accumulation of phenolic compounds under the action of UV radiation is a universal mechanism of protection against photodamage, which was formed in the early stages of the evolution of photoautotrophic organisms. Flavonoids are localized in the epidermis of plant tissues and act as an internal filter. The content of flavonoids is determined by the genotype and due to ontogenetic patterns. Plants were grown in a greenhouse, in vessels containing 4.5 kg of air-dry soil. The repetition is threefold (3 vessels in each variant). Sowing density - 13 plants in each vessel. As a source of UV-A radiation used lamps Black Light BLUE company Philips. Plants were irradiated for 5 hours a day from 10 to 15 hours at 13, 25, 34, 43 and 52 stages of organogenesis. The magnitude of the daily biologically effective dose of UV-A radiation was 60.7 kJ / m2. The solar part of the UV spectrum in the vegetation experiment was absent in the greenhouse. The nature of changes in the content of flavonoids under the action of UV-A irradiation during the growing season of plants with the dynamics of the oxidative process has been established. The first maximum was observed during the vegetative growth period, the second - at the earing stage. The data obtained indicate that flavonoids have ontogenetic conditionality and perform photoprotective functions. The increase in their content under the action of UV-A radiation is accompanied by an increase in resistance to photodamage, which is confirmed by the formation of grain yield.

Abstract Older adults consistently report young subjective age and provide high ratings of their subjective health. The current research examined which social comparisons older adults make when they assess their subjective age and health, as well as the effects of experimentally manipulated social comparisons on these assessments. In Study 1, 146 participants (aged 60 and over) reported to whom they compared themselves when assessing their subjective age or health. In Study 2, 100 participants (aged 60 and over) reported their subjective age and health after receiving feedback that compared them to younger adults or to their peers. Study 1 shows that participants compared themselves primarily to their peer group. Yet, individuals who selected a younger comparison group when assessing subjective age reported a younger subjective age, better self-rated health and more positive expectations regarding ageing relative to those who selected their peers as a comparison group. No equivalent differences emerged in any of the measures when participants were divided by their selection of comparison group after providing their self-rated health ratings. In Study 2, feedback that emphasised the performance of younger people led to reports of younger subjective age relative to feedback that emphasised peer performance, with no equivalent difference for self-rated health. These findings help explain why older adults feel younger and healthier than they actually are. We suggest that older adults use social comparisons as a strategy that protects them from the negative effects of ageing on self-perception.

To increase the embryonic and postembryonic viability of poultry, along with selection work, optimization of the microclimate parameters of poultry houses and rations, it is also advisable to develop resource-saving and environmentally friendly methods of using biologically active substances. It was shown that the treatment of eggs with a composition of solutions of natural metabolites (colamine, succinic acid and Ribav) in optimal concentrations stopped and prevented the negative effects of stress. Positive biochemical and morphological changes were observed in the development of chick embryos. An increase in chick withdrawal, a decrease in all incubation waste, an increase in the activity of antioxidant defense enzymes, and a decrease in the content of malondialdehyde in the blood serum of chickens were found.

Evaluation of the immune system parameters can be used in order to assess capacity to adapt under conditions of increased external chemical load, including exposure to metals, which can exert either activating and inhibitory effects upon immune regulation parameters. The aim of this work was the analysis of immunoregulatory markers in a children’s population who consumed water with high strontium content (a sample from the Perm region). We carried out immunological evaluation of the children aged 7 to 12 years, living at a territory with a high strontium content in the drinking water. The comparison group included children from the conventionally clean region. We studied differential changes in cellular immunity (phagocytosis rates), humoral factors of immune defense (serum immunoglobulins), development of specific sensitization for strontium, as well as the processes of apoptosis triggering and regulation. A 3.68-fold increase in strontium levels was shown in fresh water within observation area, and the average  blood strontium content in the children of appropriate observation group was 1.55-fold higher than in children of the comparison group. At the same time, 1.2-fold increase in phagocytic activity determined as phagocytic number and phagocytic index was found, as compared to the control group. In 80% of the subjects, a reduction in serum IgG level was observed when compared to physiological norm, as well as a significant decrease in IgG and enhance in IgM production against the levels found in the comparison group. Wehave also shown an enhanced total sensitization in 55.0% of the observation group as shown by the total IgE test compared with normal age ranges, as well as excessive specific sensitization to strontium by 2.49 times, according to the IgG criterion. Disturbance in apoptosis triggering was associated with decreased number of CD95+ lymphocytes and TNFR1+ cells (2.8-fold compared to reference values), shifted balance in apoptogenic proteins, an average of 2.6-fold decrease in Bcl-2 expression, a 2.8-fold reduction of the p53 transcription factor expression relative to the reference interval. Thus, we have shown an ability of strontium excess in drinking water to influence the most important indices of immune regulation in pediatric population. These changes may serve as indices of populational health status under of external strontium exposure.

Microcystins (MCs) are cyanotoxins produced mainly by freshwater cyanobacteria, which constitute a threat to public health due to their negative effects on humans, such as gastroenteritis and related diseases, including death. In Mozambique, where only 50% of the people have access to safe drinking water, this hepatotoxin is not monitored, and consequently, the population may be exposed to MCs. The few studies done in Maputo and Gaza provinces indicated the occurrence of MC-LR, -YR, and -RR at a concentration ranging from 6.83 to 7.78 µg·L−1, which are very high, around 7 times above than the maximum limit (1 µg·L−1) recommended by WHO. The potential MCs-producing in the studied sites are mainly Microcystis species. These data from Mozambique and from surrounding countries (South Africa, Lesotho, Botswana, Malawi, Zambia, and Tanzania) evidence the need to implement an operational monitoring program of MCs in order to reduce or avoid the possible cases of intoxications since the drinking water quality control tests recommended by the Ministry of Health do not include an MC test. To date, no data of water poisoning episodes recorded were associated with MCs presence in the water. However, this might be underestimated due to a lack of monitoring facilities and/or a lack of public health staff trained for recognizing symptoms of MCs intoxication since the presence of high MCs concentration was reported in Maputo and Gaza provinces.
