All four variants of immune responses are virtually unmistakably (with an accuracy of 97,7%) predicted by a set of 20 predictors including 12 immune blood parameters and one saliva parameter, 4 information parameters, 2 fecal microbiota parameters as well as erythrocyturia. In the next study discriminant analysis revealed that constellation 8 HRV and 5 Endocrine parameters as well as Gender of the patient predicts the nature of the immune response with an accuracy of 90,9%. The <strong>purpose</strong> of this study is to search for predictors of immune responses among the registered Metabolic parameters. <strong>Material and methods. </strong>The object of observation were 34 men and 10 women aged 24-70 years old, who came to the Truskavets’ spa for the treatment of chronic pyelonephritis combined with cholecystitis in remission. We determined them the Electrokinetic index, Lipoproteines spectrum, plasma and daily urine levels of Electrolytes and Nitrous metabolites as well as basal and postprandial volume of gall-bladder. <strong>Results.</strong> Discriminant analysis revealed 16 parameters as the predictors. Of these, 3 reflect the level of Plasma Electrolytes, 5 - the Urine Electrolytes, another 2 - the levels of plasma and urine Urea. Other predictors were: Very Low Density Lipoprotein Cholesterol plasma level, Body Mass index, fasting gallbladder volume and 30 minutes after cholekinetics, Electrokinetic index, and patient Age. These predictors, taken together, determine the nature of the immune response with an accuracy of 95,5%. <strong>Conclusion</strong>. The variety of immune responses to adaptogenic balneotherapy is quite strictly conditioned by the initial state of the neuroendocrine-immune complex, microbiota, cholekinetics and metabolism, as well as the age and sex of patients. <strong>Key</strong> <strong>words: Electrolytes</strong><strong>;</strong><strong> Nitrous and Lipoproteins parameters</strong><strong>;</strong><strong> Cholekinetics</strong><strong>;</strong><strong> Immunity.</strong>

Full textAbstract:
IntroductionThe potential involvement of the immune and inflammatory systems has been extensively studied in mood disorders (MDs). Despite these findings and despite the fact that the pathogenetic role of altered immunologic and metabolic profiles in MDs is being confirmed in many current studies, there is still a lack of consensus about it, due to controversial results.ObjectivesThe present study aimed to appraise peripheral metabolic parameters (blood glucose, lipoproteins, triglycerides, uric acid, blood urea nitroge [BUN], transaminases and others9 and plasma/serum levels of essential nutrients (vitamin D, B12, folate and homocysteine) in a group of inpatients affected by MDs, as compared with healthy controls.MethodsMethods. Ten ml of venous blood was drawn from fasting subjects. The metabolic parameters and vitamins were measured according to common clinical-chemistry methods.Comparisons for continuous variables were performed by the Student’s t-test for variables that follow a normal distribution, and by the Wilcoxon-Mann-Whitney test for variables not normally distributed. The correlations between biological markers were explored by calculating the Pearson’s correlation coefficient or Spearman rank correlation.Results Most patients showed loer circulating vitamin D levels, in respect to both control subjects (P< .0001) and the normative cut-off values. This finding was paralleled by increased serum homocysteine concentrations i (P<.0001), indicating an imbalance in their methionine metabolism. Homocysteine levels were negatively correlated with vitamin D, vitamin B12 and folate in control subjects, but not in patients. In addition, patients displayed higher blood glucose and lower BUN than controls, indicating an impaired protein-to-carbohydrate metabolism and/or altered nutritional/dietary status.ConclusionsWe provide herein further support to the notion that MD patients are a population where vitamin deficits, dysmetabolism and/or dietary defects are common feature, and, s such, they might be more vulnerable to a variety of somatic illnesses than the general population. This cross-sectional investigation, albeit preliminary, might contribute to improve the characterization and the monitoring of the clinical status of mood disorder patients, as well as to identify new molecular targets for more tailored treatments ad of more pointed health-care intervention,Disclosure of InterestNone Declared

Environmental carcinogens or exogenous carcinogens includes chemical, biological, and physical agents that have the potential to increase cancer risk because of prolonged high prevalence of exposure. Exposure can be through the respiratory, digestive, cutaneous or other possible contamination routes. N-Nitroso-N-ethyl urea (NEU), an ethylating agent has been described as a very potent transplacental teratogen and carcinogen in rodents. Plants have been investigated to protect against the effect of environmental carcinogens due to their arrays of phytochemicals. 35Female albino rats of average ages 10weeks were rats exposed to freshly prepared 3 fractionated doses of 50 mg/kg N-Nitroso-N-ethyl urea dissolved in 1/15 M phosphate buffer, given intraperitoneally and treated with varying concentrations of Vernonia amygdalina leaf aqueous extracts. At the end of the test period, hematological and biochemical parameters were determined in blood samples. Compared to the control group, the NEU exposed rats treated group showed significances in several hematological parameters, including decreases in white blood cell (WBC), red blood cell (RBC), and platelet (PLT) counts. Furthermore, in comparison to the control group, the NEU exposed rats showed significantly (p<0.05) increased blood glucose, serum total cholesterol, low density lipoprotein (LDL-cholesterol), triacylglycerols levels and igh density lipoprotein (HDL-cholesterol) level. The hematological and biochemical parameters in the NEU exposed rats treated group were similar to control group. V. amygdalina extract significantly (P<0.05) restored the hematological and biochemical parameters in N-Nitroso-N-ethyl urea exposed rats

Full textAbstract:
Current feed formulations within the aquaculture industry have tended to rely on high dietary lipid thus offsetting relatively expensive protein as a source of energy. In this way, protein can be ‘spared’ for synthesis of new tissue and the high lipid content can also fulfil both fish and consumer essential fatty acid (EFA) requirements. However, the main disadvantage of feeding high lipid levels to farmed fish is a surplus of fat deposition in the flesh and other important tissues, which can detrimentally impact on quality characteristics central to the human consumer. However, based on previous work in other animal models, it is entirely feasible that supplementation of the diet with bioactive fatty acids such as conjugated linoleic acid (CLA) and tetradecylthioacetic acid (TTA) may mitigate the deleterious effects of feeding farmed fish high fat diets by reducing fat deposition in particular. The general objective of this research work was to test the hypothesis that CLA and/or TTA could augment growth, reduce fat deposition and enhance fatty acid composition via incorporation of these bioactive fatty acids, and increase n-3 highly unsaturated fatty acid (HUFA) levels in the flesh of commercially important fish species such as Atlantic salmon (Salmo salar), Atlantic cod (Gadus morhua L.) and rainbow trout (Oncorhynchus mykiss). This project also considered the influence of CLA and TTA on enzymes and transcription factors thought to be pivotal in lipid metabolism and fatty acid oxidation in particular. A subsidiary aim of this research work was to investigate the immunological impact of dietary CLA and TTA administration in these fish. The results of this project have revealed that the hypothesis was only partly proved. There was no effect in growth or biometry after either CLA or TTA supplementation in any of the fish species investigated. Additionally, there were few physiologically significant effects on fat levels on fish as a result of TTA or CLA administration. However, there were a number of effects on fatty acid metabolism including inhibition of steroyl coenzyme desaturase (SCD) in cod and trout in particular and also enhancement of hepatic n-3 HUFA levels in trout. Importantly, it was determined that both TTA and CLA could be incorporated into the flesh thus providing a vehicle through which these bioactive fatty acids can be delivered to the consumer. There were also a number of beneficial effects on activity and gene expression of a number of enzymes and transcription factors thought to be fundamental to the modulation of fatty acid oxidation in particular. However, the effects on gene transcription and biochemistry had little impact at the whole body level. This research work also showed that there were no detrimental effects on immune status after supplementation with dietary CLA or TTA. Conclusively, this thesis has contributed to the overall understanding of the influence of dietary CLA and TTA in farmed fish.

The article is a presentation of the results of studies and calculations of climate parameters associated with anthropogenic thermal pollution of the environment. They indicate that the increase of atmospheric concentrations of carbon dioxide, methane, and nitrous oxide cannot be a cause of climate warming. The article provides information about the working principle of the natural mechanism of automatic maintenance of temperature climate parameters. The authors show that all of the gases molar mass of differs from the molar mass of nitrogen are the working bodies of the procedures for moving heat from the stratosphere to space. Water vapor is the only greenhouse gas, and to deal effectively with water vapor in the atmosphere is impossible. However, the work contains an assessment of the feasibility of some ways to assist the natural mechanism of removing heat to space. Some methods and tools of world energy development are suggested in the article. These methods could lead to a substantial reduction of anthropogenic thermal pollution of the planet.

Full textAbstract:
Climate change and agriculture have a dual mode of relationship. Agriculture is an important sector of the country’s economy and it significantly contributes to climate change by releasing greenhouse gases (GHGs) to the atmosphere. On the other hand, climate change is a global threat to food security and it can affect agriculture through variation of weather parameters. Reducing GHGs emission mainly methane (CH4) and nitrous oxide (N2O) from the agriculture could play a significant role in climate change mitigation. N2O is a potent greenhouse gas mainly emitted from rice-wheat cropping system. Agricultural lands are considered as one of the important anthropogenic sources of N2O emissions and it account almost 69% of the annual atmospheric N2O emission and application of commercial fertilizers is considered as a major contributor to the N2O emission. This book chapter focuses on the feasible soil and crop management practices to reduce the N2O emission from agriculture without compromising the productivity. Different environmental factors that have a major impact on N2O production are also discussed in this chapter. On urgent basis, the world needs to reduce the anthropogenic N2O emissions from agriculture and adapt its sustainable cropping system and food-production system to survive with climate change.

Full textAbstract:
Amphiphiles form a large group of supramolecular structures can aggregate and be adsorbed spontaneously at the interface. Amphiphilicity is a feature of polar contrast between the groups that make up a molecule and their spatial separation. The most important classes of amphiphiles are surfactants, lipoproteins, and polymers that have hydrophilic and hydrophobic chemical moieties covalently bonded and spatially separated. Since surfactants are widely used in various industrial fields, we decide to focus on surfactants in addition to a brief review of the other amphiphiles. Surfactants are used in industrial applications and consumer products, from medical to cosmetics and food industry. Various industries require new surfactants from sustainable and renewable raw materials with improved performance, biocompatibility and minimal environmental impact. For example, liquid phase exfoliation and dispersion methods using surfactants in the solvent media have recently gained lots of attention because of their great potential for large-scale production. Notably, an ideal exfoliation for reaching desired graphene and CNTs may be achievable by molecular engineering of surfactants to improve the quality of molecular interactions. This chapter experimentally and theoretically highlighted physico-chemical characteristic parameters, and interactions of the components, which are essential to design and discover efficient exfoliation and dispersion systems.

Full textAbstract:
Metabolic syndrome (MS) is a diverse condition linked to an elevated risk of cardiovascular issues. Emerging evidence from various types of research, including experimental, translational, and clinical studies, has indicated that obstructive sleep apnoea (OSA) is connected to both existing and newly developing aspects of MS. The plausible biological explanation centers primarily around one of OSA's main features, intermittent hypoxia. This leads to heightened sympathetic activity with cardiovascular consequences, increased liver glucose production, insulin resistance due to inflammation in adipose tissue, dysfunction in pancreatic β-cells, elevated lipid levels through deteriorating fasting lipid profiles, and decreased removal of triglyceride-rich lipoproteins. While several interconnected pathways exist, the clinical evidence primarily relies on observational data, making it difficult to establish causality. The co-occurrence of visceral obesity and potential confounding factors like medications complicates the assessment of OSA's independent impact on MS. In this chapter, we re-evaluate the evidence regarding how OSA and intermittent hypoxia may contribute to adverse effects on MS parameters independently of body fat. We place particular emphasis on recent findings from intervention studies. This chapter outlines the research gaps, the challenges faced in the field, potential directions for future exploration, and the necessity for more high-quality data from intervention studies that address the influence of both established and promising therapies for OSA and obesity.

Introduction: The impact of harmful occupational factors has adverse effect to human body functional state due to regulatory mechanisms tension, which contributes to occupational diseases and premature aging development. The goal of the work: dust professions workers comparative assessment of cardiovascular risk indicators and elastic properties of vascular wall. Methods: First group included workers exposed to industrial aerosols during work (17 people), second group included workers working out of contact with industrial aerosol (15 people). The groups were comparable by age (53.0±1.43 and 54.7±2.41 years, respectively (p > 0.05). Vascular wall arterial stiffness were assessed by volumetric sphygmography, electrical impedance parameters, indicators of carbohydrate, lipid and nitrogen metabolism, cardiovascular risk assessment carried out by SCORE scale. Results: Working with dust factor, under lower levels of body mass index and lipid spectrum indices, higher indicators of vascular wall stiffness and pulse wave propagation velocity were noted compared to workers without contact with industrial aerosols. Stiffness indicators showed positive relationship with age, urea levels, high-density lipoproteins. Indicators of lipid metabolism (total cholesterol, triglycerides and low-density lipoproteins) showed positive relationship with fat mass level and negative relationship with musculoskeletal mass proportion and specific basal metabolism. Conclusions: There is reason to assume that dust load is probably significant cardiovascular risk factor and may be comparable in importance to traditional risk factors.

The human health has many important aspects and the cholesterol regulation is one of them. The low-density lipoproteins cholesterol (LDL-C) transports plasma cholesterol (about 60%) and it is responsible by its depositing on arteries for atherosclerotic process, increasing the probability of cardiovascular events. High-density lipoproteins (HDL) can reduce this process by transport about 30% of plasma cholesterol. The balance is modified in the process of aging and depend also of other factors as diet, and physical exercises. An educational tool is proposing that use basically two mathematical models: (1) a simple one by two compartment model proposed by Wona & Hrydziuszko that include an dietary term, and (2) a more complex one that include the mechanism of simulation of aging proposed by Mc Auley. The values of parameters for both models are taken from literature and the user can modify them in order to test and simulated the models. The diet is modeled in the first model as an additive variable, and other variable are deduced from stability analysis and are assumed based on heuristic trials. In the second model, the mechanism of aging is simulated empirically (because the complete mechanism is not known yet) by increasing the LDL-C values and decreasing the number of hepatic LDL receptors (HLDLR) by decreasing the parameter that represents rate of synthesis. The tool has a library with selected curves for (HDL-C) and (LDL-C) from different countries of the world by age and sex extracted from literature. In the future development, this information will be used to model and analytic additive function for (LDL-C) curve by fitting of parameters with experimental one in system of differential equations that models the cholesterol homeostasis.

Full textAbstract:
This paper presents a quasi-stationary one-dimensional mathematical model of the combustion chamber of a hybrid rocket engine. The model is based on stationary balance equations, considering time-varying input parameters. It makes it possible to quickly estimate the variability of parameters such as pressure, velocity, or temperature of gases inside the combustion chamber during engine operation. In addition, the assumption of a global paraffin oxidation reaction in nitrous oxide allows the determination of the composition of the exhaust gases. The results are consistent with numerical data from other researchers available in the literature.

Full textAbstract:
Nitrous oxide (N2O) is considered a potent and very harmful greenhouse gas (GHG), and wastewater treatment plants (WWTPs) are considered a potent source of it. Predicting N2O emissions is a first step in reducing these. One way of doing this is by using a process-based biokinetic model, based on Activated Sludge Models (ASMs) that have been extended to include the N2O production pathways. Alternatively, data-driven Artificial Intelligence (AI) models can be used to predict N2O emissions. In this paper, a biokinetic model has been built and calibrated for the Amsterdam West WWTP (1.1 Million PE; 168 MLD), using the EnviroSim software, BioWin®. A comprehensive monitoring campaign was conducted to characterise the common quality parameters (COD, TKN, TP, TSS, etc.) into their fractions, which were then used as BioWin model inputs. The calibration was conducted in two stages to predict effluent quality followed by model calibration to predict N2O emissions. Additionally, an Artificial Neural Network (ANN) based model was developed using pertinent process parameters, such as the influent flowrate, and NH4 in the aerobic tank as inputs to predict the N2O concentration in the gas phase. Preliminary results demonstrate that the ANN model outperforms the BioWin model in terms of prediction accuracy. Still further work is required to better understand the pros and cons of the two modelling approaches.

Full textAbstract:
Taking into account the importance of animal health and the quality of the products obtained from it, in recent years the emphasis has been placed on growth stimulants of natural origin. In the research, we aimed to carry out a study highlighting the action of the ZooBioR product from Spirulina platensis on health, and the marker parameters of lipid metabolism in laying quails. The research was carried out on 4 batches of birds (50 quails/batch). In three batches the feed was supplemented with ZooBioR in doses of 10.0; 15.0; 20.0 mg active substance/kg feed. Research has shown that the tested product is well tolerated by quails. The tested product improves the metabolic processes in the bird's body, especially the lipid metabolism: it definetely decreases the amount of cholesterol and triglycerides in blood, at the first stage of research, and the total lipids and β-lipoproteins values. In addition, at the end of the study, the β-lipoprotein values, in the blood of the birds treated with ZooBioR, increased by 2.5-52.1% compared to the control, a positive effect of the tested remedy on the metabolic health of the birds in general, and especially on the lipid metabolism.

Full textAbstract:
This paper presents an alternative method for the hermeticity assessment of MEMS micro-packages, and the first experiments performed using this technique. The method consists in monitoring the internal gas pressure of the cavity by Fourier Transform Infra Red (FTIR) spectroscopy. The package’s hermeticity is then deduced from the pressure variations. In order to carry out the IR transmission measurements, nitrous oxide was chosen as bombing gas due to its excellent absorption properties for mid-IR radiations. The method was applied to BCB-sealed silicon micro-packages and allowed to study the influence of different parameters like the sealing ring dimensions or the internal volume on their hermeticity. Additional measurements were carried out on hermetic packages, with an additional organic coating. These experiments validated the method for micro-packages with a volume of 5 mm3 or more.

Full textAbstract:
An experimental study on nitrous oxide (N2O) reduction with circulating ashes of circulating fluidized bed (CFB) boilers was conducted for the development of an effective and economical technology to reduce the N2O emission from CFB boilers. The experiments were conducted with three kinds of circulating ashes, by using a fixed bed reactor with a diameter of 25mm, under various conditions of different operational temperatures, initial N2O concentrations, NH3 additions and O2 concentrations. The effects on N2O reduction were compared that with quartz sand. The experimental results showed that circulating ashes may possess remarkable catalytic effect on N2O reduction and the intensity of the catalytic effect strongly depends on operational parameters such as reaction temperature and O2 concentration. It was also found nitric oxide (NO) was produced during the process of N2O reduction and its concentration also strongly affected by reaction temperature and O2 concentration. The mechanisms of N2O reduction were discussed. The study confirmed the feasibility of injecting NH3 at the cyclone entrance of CFB boiler to form a selective catalytic reduction (SCR) process for N2O emission without using extra catalyst and provided some guidance to choose the operational parameters for N2O reduction with circulating ashes.

Full textAbstract:
NOx exhaust emissions for gas turbine engines with lean-premixed combustors are examined as a function of combustor pressure (P), mean residence time (τ), fuel-air equivalence ratio (φ), and inlet mixture temperature (Ti). The fuel is methane. The study is accomplished through chemical reactor modeling of the combustor, using CH4 oxidation and NOx kinetic mechanisms currently available. The NOx is formed by the Zeldovich, prompt, and nitrous oxide mechanisms. The combustor is assumed to have a uniform φ, and is modeled using two reactors in series. The first reactor is a well-stirred reactor (WSR) operating at incipient extinction. This simulates the initiation and stabilization of the combustion process. The second reactor is a plug-flow reactor (PFR), which simulates the continuation of the combustion process, and permits it to approach completion. For comparison, two variations of this baseline model are also considered. In the first variation, the combustor is modeled by extending the WSR until it fills the whole combustor, thereby eliminating the PFR. In the second variation, the WSR is eliminated, and the combustor is treated as a PFR with recycle. These two variations do not change the NOx values significantly from the results obtained using the baseline model. The pressure sensitivity of the NOx is examined. This is found to be minimum, and essentially nil, when the conditions are P = 1 to 10atm, Ti = 600K, and φ = 0.6. However, when one or more of these parameters increases above the values listed, the NOx dependence on the pressure approaches P raised to a power of 0.4-to-0.6. The source of the NOx is also examined. For the WSR operating at incipient extinction, the NOx is contributed mainly by the prompt and nitrous oxide mechanisms, with the prompt contribution increasing as φ increases. However, for the combustor as a whole, the nitrous oxide mechanism predominates over the prompt mechanism, and for φ of 0.5-to-0.6, competes strongly with the Zeldovich mechanism. For φ greater than 0.6-to-0.7, the Zeldovich mechanism is the predominant source of the NOx for the combustor as a whole. Verification of the model is based on the comparison of its output to results published recently for a methane-fired, porous-plate burner operated with variable P, φ, and Ti. The model shows agreement to these laboratory results within a factor two, with almost exact agreement occurring for the leanest and coolest cases considered. Additionally, comparison of the model to jet-stirred reactor NOx data is shown. Good agreement between the model results and the data is obtained for most of the jet-stirred reactor operating range. However, the NOx predicted by the model exhibits a stronger sensitivity on the combustion temperature than indicated by the jet-stirred reactor data. Although the emphasis of the paper is on lean-premixed combustors, NOx modeling for conventional diffusion-flame combustors is presented in order to provide a complete discussion of NOx for gas turbine engines.
