Body Mass Index and Indicators of Lipid Exchange in Liver Steatosis of Alcoholic and Nonalcoholic Genesis in Residents of Rural Area: Similarities and Differences

Non-alcoholic fatty liver disease (NAFLD) and alcoholic liver disease (ALD) are serious health problems. Features of liver steatosis (LS) due to NAFLD and ALD in rural areas, including lipid metabolism indicators, depending on body mass index (BMI), have not been thoroughly studied.Aim. To study the features of lipid metabolism in residents of rural area in LS due to NAFLD and ALD depending on the BMI.Materials and Methods: 1152 residents of a rural therapeutic site were surveyed. Lipidograms and BMI were analyzed in patients with LS at NAFLD and ALD.Results. There were no patients with a reduced BMI in the rural medical site. Persons with BMI ≥ 25 among patients with LS on the background of NAFLD (98.2 %) are significantly more frequent than on the background of ALD (55.1 %) (p < 0.001). Among subjects with normal BMI there were more patients with ALD (44.9 %) than with NAFLD (1.8 %) (p < 0.001). There were no significant differences in age in patients with in NAFLD depending on BMI (p > 0.05). Patients with LS of ALD with an increased BMI were older than those with a normal index (p < 0.05). Also, there were no differences in lipidograms with LS on the background of NAFLD and ALD depending on BMI (p > 0.05). Triglyceride levels (TG) and atherogenic coefficient (AC) were significantly higher (p < 0.05 in both cases) in LS with ALD than in patients with NAFLD. Findings. Disorders of lipid metabolism were found in patients with LS with both increased BMI and normal. At the rural therapeutic site, patients with LS due to ALD have more pronounced lipid metabolism disorders than those ones with NAFLD, regardless of BMI

INFLUENCE of inhalation coal and rock dust on morphological changes of heart muscle (experimental research)

Early stages of coal-dust exposure on laboratory animals do not cause morphological changes in heart muscle. Later periods (6—9 weeks of experiment) are accompanied on the one hand expressed compensatory-adaptive processes, on the other hand. - selective accumulation of lipofuscin in cardiomyocytes. Accumulation of lipofuscin is directly dependent on the duration of the adverse effects of the dust factor and. may be one of the main morphological markers of deep damage and cell death with prolonged exposure to coal and rock dust

Eating behavior features and preferred diets in underweight and obese young men

BACKGROUND: Actual nutrition and eating behavior features affect the formation of excess or underweight which in turn are risk factors for the development of chronic non-infectious diseases.AIM: To assess eating behavior features and consumption of basic nutrients in relation to metabolic disorders in underweight and obese young men of military age.MATERIALS AND METHODS: The study enrolled 86 young men aged 18 to 23 years that were referred by military enlistment office due to violations in body weight and examined in the hospital. Participants were divided into 2 groups depending on the value of the body mass index (BMI): group 1 (n=41) — underweight (Uw) young men; group 2 (n=45) — obese (Ob) young men. Anthropometric, hormonal and biochemical parameters of the body were measured; the type of eating disorder (ED) was evaluated using the Dutch DEBQ questionnaire, the presence and severity of anxiety and depressive disorders were assessed using the Hospital Anxiety and Depression Scale; assessment of the actual diet was performed using «Somatonic» computer soft.RESULTS: Absolute intake of all essential nutrients was higher in Ob young men; the relative consumption of protein and cholesterol was higher in Uw young men, whereas relative fats intake was higher in Ob group. EDs were statistically significantly more common in Ob young men. The values of all anthropometric indicators were higher in Ob group, while Uw young men predominantly demonstrated deficiency of the body fat component which did not affect key hormonal and metabolic indicators values. In Ob young men carbohydrate metabolism hormonal regulation disorders along with increased blood pressure were revealed.CONCLUSION: The ratio of proteins and fats intake should be taken into account in dietary regimens composition; Uw young men need to increase the proportion of fat and reduce protein intake, whereas Ob young men on the contrary need to reduce the proportion of fat and increase amount of proteins enhancing energy expenditure due to the specific dynamic food action

Effect of platinum nanoparticles on morphological parameters of spring wheat seedlings in a substrate-plant system

When wheat is cultivated in the media contaminated with platinum nanoparticles, the change in the morphological and physiological indexes of wheat seedlings depends on the physico-chemical parameters of the germination substrate. The changes become less pronounced with the decreasing bioaccessability of the nanomaterial in the following order: water suspension – luvisols – phaeozems. Contamination with nanoparticles affects the height parameters and activates the mechanisms protecting the plant from stress. When using wheat seedlings as test organisms for biotesting the environmental safety of NPs, it is advisable to use the following parameters: weight of roots, weight of aerial part, leaf area, and flavonoid content

Pyrrolylquinoxaline-2-one derivative as a potent therapeutic factor for brain trauma rehabilitation

Traumatic brain injury (TBI) often causes massive brain cell death accompanied by the accumulation of toxic factors in interstitial and cerebrospinal fluids. The persistence of the damaged brain area is not transient and may occur within days and weeks. Chaperone Hsp70 is known for its cytoprotective and antiapoptotic activity, and thus, a therapeutic approach based on chemically induced Hsp70 expression may become a promising approach to lower post-traumatic complications. To simulate the processes of secondary damage, we used an animal model of TBI and a cell model based on the cultivation of target cells in the presence of cerebrospinal fluid (CSF) from injured rats. Here we present a novel low molecular weight substance, PQ-29, which induces the synthesis of Hsp70 and empowers the resistance of rat C6 glioma cells to the cytotoxic effect of rat cerebrospinal fluid taken from rats subjected to TBI. In an animal model of TBI, PQ-29 elevated the Hsp70 level in brain cells and significantly slowed the process of the apoptosis in acceptor cells in response to cerebrospinal fluid action. The compound was also shown to rescue the motor function of traumatized rats, thus proving its potential application in rehabilitation therapy after TBI. © 2020 by the authors.

Cytokinesproduction by blood immune cells in patients of different age groups with invasive ductal carcinoma of no special type and lymphatic metastases

The aim of this study was to evaluate production of cytokines by the blood immune cells in patients of different age groups with invasive non-specified type mammary ductal carcinoma, with or without metastases. Production of cytokines by periphery blood immunocompetent cells, either spontaneous and stimulated with polyclonal activators, was assessed in 82 patients with invasive mammary ductal carcinoma. The concentrations of IL-6, IL-8, IL-10, IL-17, IL-18, IL-1p, IL-1ra, TNFa, IFNy, G-CSF, GM-CSF, VEGF и MCP-1 were determined by solid-phase enzyme-linked immunosorbent assay. The patients were divided into 2 age groups: the first group consisted of 48 patients from 45 to 60 years old; the second group consisted of 34 older patients (61 to 75 years old). Metastases in local lymph nodes were documented in twenty patients from the first group and nine patients from the second group. The younger patients (45-60 years old) with metastases in local lymph nodes showed higher polyclonal activation index of IL-4 and IL-1ra production, when compared to the patients without lymphatic metastases. As for the older patients (61 to 75 years old), their polyclonal activation index of IL-6, IL-8, IL-1ra, G-CFS, GM-CSF production was significantly lower in cases of local lymph nodes metastases. The latter was due to higher level of spontaneous production, which suppressed the influence of polyclonal activators. The index of polyclonal activation upon production of cytokines in patients with lymphatic metastases was shown to be significantly higher for the age group of 45 to 60 years than in the age group of 61 to 75 years old. This fact suggested a highly stimulating effect of polyclonal activators in patients younger than 60 years. It was found that correlation between the index of polyclonal activation of cytokine production, and the indexes of ER, PR, HER2/NEU and Ki-67 receptor expression, which are used for the determination of molecular genetic subtype of the tumor, differ significantly for the distinct age groups

Blood biomarkers and Ki-67 proliferation marker in breast cancer

Metastasis is the leading cause of death in patients with breast cancer (BC). It is known that the lesion of regional lymph nodes by tumor cells is more common in tumors with higher proliferative activity. Moreover, there is literature evidence on effects of cytokines and proteins upon the migration potential of the tumor. The aim of our work was to study the correlation between the concentrations of cytokines, proteins, and expression of Ki-67 proliferation marker in breast cancer with histology of non-specific invasive carcinoma.On the basis of pathological findings, 16 patients had metastases in regional lymph nodes (group I), and 18 patients had no detectable metastases (group II). Solid-phase enzyme immunoassay was used to determine concentrations of 14 cytokines in the supernatants of immunocompetent blood cells, i.e., IL-2, IL-6, IL-8, IL-10, IL-17, IL-18, IL-1β, IL-1ra, TNFα, IFNγ, G-CSF, GM-CSF, VEGF and MCP-1, and concentrations of 6 proteins were determined in blood serum: estrogen and progesterone receptors, cadherin-E (CDH1), plasminogen activator type 1 (PAI-1), mucin 1 (MUC1), heat shock protein 90αA1 (HSP90αA1). Immunohistochemical study of Ki-67 expression was performed in paraffin sections of tumors using monoclonal antibodies.The study showed that Ki-67 expression in tumor tissues and blood concentrations of IL-6, IL-8, IL-1β and TNFα were higher in group I patients. On the contrary, blood concentrations of CDH1 and PAI-1 were higher in group II patients. It was found that Ki-67 showed both inverse correlations with CDH1 and PAI1, and direct correlations with IL-8 and TNFα. CDH1 had a direct correlation with PAI1, and inverse correlations with IL-6, IL-1β and TNFα. The studied cytokines showed direct correlations with each other. The analysis of ROC curves showed good quality and optimal values of the cut-off points for Ki-67 expression, cytokine and protein concentrations, thus allowing best prediction for detectable lymphatic metastasis.On the basis of these results, a quotient was proposed, which represents a ratio of CDH1 contents to the sum of IL-1β and TNFα concentrations in blood samples, which can help identification of the patients with breast cancer at risk for lymphatic metastasis
