The article focuses on the study of changeability of morphological and physiological characteristics of 850 specimens of beluga ( Huso huso ) and sturgeon ( Acipenser gueldenstaedtii ) juveniles obtained at the Ikryaninskiy and Bertyulskiy sturgeon hatcheries in the Astrakhan region. There was determined weight of the body, heart, liver and spleen, as well as the relative mass of these organs - cardiosomatic, hepatosomatic indices and index of a spleen. Sturgeon juveniles were studied within 47-127 days, beluga juveniles within 40-116 days. Certain tendency was noted: cardiosomatic index decreased with aging in both sturgeon and beluga, i.e. the relative weight of the heart in ontogenesis changes inversely to the body weight, which corresponds to literature data. Comparison of the dynamics of the liver relative weight in sturgeon and beluga juveniles showed that it coincides at two segments: maximum raise to 50-60ths day from the birth and a gradual decrease in older juveniles. The value of spleen index in juveniles of both types rose with aging. It was found in the course of the study that the size of internal organs could change, getting smaller under unfavorable factors, in particular, when juveniles suffer from the lack of feeds. In such circumstances the dynamics of developing main internal organs drastically slows down, which reflects on physiological adequacy (quality) of juveniles. Thus, morphological and physiological indicators characterizing the degree of the vitals development can be used not only for characterizing species differences of the investigated group of fish at all stages of ontogenesis, but as important factor for assessing conditions of Russian sturgeons juvenile breeding and the degree of morphological and physiological maturity of the juveniles before releasing into the natural water body.

Clathrochelate Complexes

We studied the chronic toxicity of the compounds of Iron(iv). We monitored the dynamics of the body weight, relative weight coefficients of the internal organs, the content of the hemoglobin, the morphological parameters of blood, and biochemical parameters of serum of blood of quails after use of Iron(IV) clathrochelate complexes at the doses 1/10 and 1/5 DL50 them for 30 days. Daily drinking of quails of experimental groups of solution of Iron(IV) clathrochelate complexes3 at the doses 76.43 and 152.86 mg/kg of body weight caused the reduction of body weight by 3 and 5% respectively on the thirtieth day. A tendency to increase the relative weight of the kidneys and to decrease the relative weight of the liver, heart and spleen showed an excessive load of Iron(IV) clathrochelate complexes on the internal organs of quails. Hemoglobin in the blood of the quails of the experimental groups was less by 2-34% (P 0.05) than the control indicator but the indicator of the number of erythrocytes in the quails of the control and experimental groups for 30 days was within the physiological values. The use of Iron(IV) clathrochelate complexes caused the development of hypoproteinemia, hypoalbuminemia, and short-term hypoglycemia in the serum of the blood of the quails of the experimental groups. Changes in an activity of alanine aminotransferase and aspartate aminotransferase for 30 days were not expressed, but the activity of alkaline phosphatase was significantly higher compared to the control indicators during the experimental period. Drinking the solution of Iron(IV) clathrochelate complexes caused hypercreatinemia and hyperuricemia, which indicates a decrease in the filtration capacity of the kidney glomeruli. We have seen an increase in the levels total Calcium and inorganic Phosphorus.

Diagnosis Method

Three-cycle acupuncture is a new acupuncture practice. This application is an objective patient-oriented application instead of subjective methods used in diagnosing acupuncture. Thus, the diagnosis and treatment of acupuncture are enlightened and made easier. The proper flow and quality of Chi are fundamental to treatment and optimal health in Chinese medicine. In the body, the channels of energy known as meridians connect to the internal organs so that the qi of the organs flows to its associated body parts. In Chinese Traditional Medicine, energy flows through our 12 main meridians or energetic pathways, in two-hour blocks. Chi begins its daily flow in the Lungs and traverses to the Large Intestine before continuing to its next destination. It finally stops at the Liver, before it begins again. If the chi is blocked in a certain organ, it will not be able to completely activate that organ or continue its journey with enough intensity to fully benefit the next organ system. If we provide the flow of Chi in the pathological cycle, the cycle starts and the complaints disappear. With this acceptance, we introduced the concept of three-cycle acupuncture. Thus, we can only perform treatment without the need for another diagnosis method. We used the Yuan points of the organs belonging to the pathological cycle to remove the obstruction. The method was very effective and we got very good answers. We have been using the method in our polyclinics for five years.

Neoplastic Disorders

The skin may be adversely affected by any serious medical illness, often as a secondary process related to infection, trauma, nutritional deficiencies, and other factors. Disease-specific skin involvement occurs commonly in some conditions, and is best characterized in cancer. Skin of the patient with advanced cancer is unique compared to other organs of the body. While the sequela of metastatic spread to internal organs often is replacement of normal tissue and resultant organ failure, widespread replacement of skin with a neoplasm is uncommon. Yet, even a local disruption of skin integrity can cause deterioration in the quality of life, debilitation, and even mortality. Other aspects of neoplastic disorders affecting the skin discussed in this chapter include accumulation of abnormally produced metabolites, adverse effects to treatment, and paraneoplastic syndromes. It is important to give dermatological aspects of disease their appropriate attention, because these can be the ones that may be dealt with efficiently and improve the patient’s quality of life.

Currently, regardless of the age and social affiliation of the population, periodontal disease is the most common. Despite the modern technologies used in dentistry, the issues of prevention and treatment in dentistry remain unresolved. Dentists are interested in the fact that periodontal diseases are inextricably linked with systemic disorders in the body, which are responsible for its physiological functions. And the effectiveness of treatment for periodontal diseases is affected by all the factors that lead to the pathological process, i.e. diseases of internal organs and periodontal diseases are inextricably linked. In this regard, the metabolism in the body of certain vitamins, in particular vitamin D, forces dentists to re-examine the effect of these vitamins on pathological factors that lead to pathologies of the oral cavity.Diseases that affect the duration and quality of life of the patient have the ability to spread widely, for example, cardiovascular diseases, tuberculosis, HIV infection, etc., and oral diseases, in particular, caries and pathologies, can be attributed to this category. periodontium.

The Impact

The article focuses on the intensive anthropogenic impact on the aquatic ecosystems, which makes it necessary to monitor the populations of different fish species. The method of mor-phophysiological indicators was used to study the kidneys of silver bream in different water bodies of the Volga Delta. The morphometric characteristics of the kidneys of silver bream are presented. It is shown that the reactions of organs and body systems are caused by the environmental impact on the living organisms, which results, in particular, in the pathological changes in the fish body. Reactions in the body of fish are the result of a combined effect of environmental factors and natural physiological processes related to feeding, migrations, generative cycles, etc. The detected changes in the organ structure make it possible to assess the impact of the environment on fish. The seasonal and sexual variability of the indices of the mesonephros of silver bream from the Volga Delta is shown. Analysis of the kidneys of fish from two water bodies showed the variability of kidney mass due to the anthropogenic load on the water body, in particular, an increase in the kidney index in silver bream Blicca bjoerkna was registered in the ecosystem with an increased toxic load. It has been stated that the increase in the relative mass of mesonephros was caused by the changes in the organ. Changes were detected both in the intratubular tissue, and in the convoluted tubules and renal capsules. The study helped to find the differences in the relative weight and structure of the kidneys of silver bream, which lives in the water bodies with different anthropogenic load. A real increase of the kidney index was found in fish from the water body with a higher level of anthropogenic impact.

The Impact

Goods of plastic, due to their durability, universality and economical properties are broadly used in all spheres of life. On the whole, polymers are inert and nontoxic, but in the process of their production, various additives are used, which on contact or introduction into an organism has a negative effect on it. In our study, we determined the impact of some types of plastic (polyvinyl chloride, polysterene and polyethylene) on the organism of laboratory animals according to changes in their body weight, indices of mass of the internal organs, and blood parameters. For the experiment, we formed four groups of white male mice at the age of 3 weeks and average body weight of 50 g. For each group, we used different litter. For group I, the litter was sawdust; and for the other groups we added plastic products in different volumes to the sawdust; for group II finely cut polyvinyl chloride, for group III cut polyethylene, and for group IV granules of polystyrene. Every 3 days, we determined the body weight of the animals, and 32 days later we determined mass of the organs, clinical and biochemical parameters of the blood. Addition of polyvinyl chloride, polyethylene, and polystyrene into the substrate for mice did not have a significant effect on tempi of growth of body weight, and also relative mass of heart and lungs. Polyvinyl chloride and polystyrene have an immune-suppressive effect, and polyvinyl chloride affects both central and peripheral organs, and polystyrene mostly harms the peripheral organs. All used types of plastic cause leukocytopenia, following which neutrophilia of band neutrophils and monocytosis takes place as a result of damage to the biological barriers. We determined the systemic toxic effect of the studied types of plastic on the internal organs, which manifested in increase in their mass (liver, kidneys), steep increase in the activity of liver enzymes (AST, ALT), simultaneous decrease in activity of alkaline phosphatase and content of cholysterol and glucose in the blood serum of the mice. Also polyvinyl chlorine, polyethylene and polystyrene cause degeneration of the epithelium of the uriniferous tubule, which is manifested in reduction of globulins and creatinine in the blood of animals from the experimental groups following increase in relative mass of the kidneys. The results of our research allow us to state that different types of plastic can cause toxic effect on animals, as well as people who are in frequent contact with them.

Abstract Human adaptation and surface sensations to environmental and climate change during outdoor exercise are often not fully consistent with the true responses of body organs. Body surface sensations may be adaptive and insensitive due to prolonged outdoor activity. This causes the body surface to be insensitive or under-responsive to rapid changes in the external environment, when the internal organs of the body are sometimes working at abnormal indications, and if this unhealthy condition continues for a long time and progresses to a dangerous condition, the danger is approaching and the body may enter a state of paralysis at this time without knowing it. This is where a wearable system that monitors environmental and physiological indicators in real time and analyzes the measured data to broadcast early warnings is needed. This system adds a certain degree of safety to outdoor sports, and the data can be used as a reference for the scientific validity of the exercise.

Improving dynamic performance is a priority when designing new rolling stock. The frequency of natural bending vibrations of the body is one of the most important standardised indicators, a preliminary assessment of which allows obtaining optimal body designs.The objective of the work is to assess the prospects for the use of elastic fastenings of equipment to increase the natural vibration frequency of wagon bodies of suburban electric trains. Calculations were based on the finite element method and block Lanczos method. It is shown that it is advisable to use the rigid area tool and linearly elastic finite elements to calculate the frequencies in the simulation. The main ranges of fastening stiffness are highlighted, where the effect of using elastic supports is different. It is proposed to determine the stiffness of fastenings according to a given vibration frequency of the equipment. When the equipment is rigidly attached, the relative mass of the equipment does not affect the body bending vibration frequency. With elastic fastening, a greater effect can be achieved with a larger relative weight of the equipment. The effect of using resilient mounts increases with heavier equipment located closer to the centre of the body.It is shown that the effect of shear admittance of fastenings on the body vibration frequency is within 1 % and may not be considered in the simulation. In the considered example of a wagon body of a suburban electric train, the use of elastic supports allows an increase in the frequency of oscillations of the body by 3–10 %.

Врановые птицы являются наиболее многочисленными в орнитофауне городов Ивановской области. В связи с этим возрос интерес к изучению эколого-физиологических особенностей врановых птиц. Данная работа просвещена изучению относительной массы внутренних органов и заболеваний у врановых. Анализ данных показал, что наибольшая относительная масса сердца была у ворона; печени - у сойки и галки; желудка - у сойки и серой вороны; кишечника - у серой вороны и сороки; легких - у ворона; почек - у галки и серой вороны; селезенки - у серой вороны; поджелудочной железы - у ворона. Наиболее часто встречаются травмы: ампутация фаланг пальцев, колотые и рваные раны, переломы трубчатых костей ног и крыльев, гемартрозы, трещины грудной кости. Вороны часто страдают пододерматитом и панкреатитом, серые вороны - спленитом, сороки и галки - ожирением, галки и сойки - гепатозом, серые вороны - гистомонозом печени. Corvids are the most numerous birds in the avifauna of the cities of the Ivanovo Region. In this regard, interest in the study of the ecological and physiological characteristics of corvids has increased. This work is enlightened by the study of the relative mass of internal organs and diseases in corvids. Analysis of the data showed that the raven had the highest relative heart mass; jays and jackdaws have the highest relative liver mass; while the highest relative mass of stomach is recorded in jays and hooded crows. The highest relative mass of the intestines is shown in hooded crows and magpies; heaviest lungs are reported for ravens. Kidneys are heaviest at jackdaws and hooded crows; spleen has the highest relative mass in hooded crows; pancreas is heaviest in crows. The most common injuries are loss of the phalanges of toes, stab and laceration wounds, and fractures of the tubular bones of the legs and wings, hemarthrosis, cracks in the chest bone. Ravens often suffer from pododermatitis and pancreatitis, hooded crows suffer from splenitis, magpies and jackdaws shows signs of obesity, jackdaws, and jays often demonstrate hepatosis, while hooded crows are susceptible to liver histomonosis.

Context: Biomimetics is a novel field of science that takes inspiration from nature and biological organisms to create and design forms. This knowledge can help improve the conditions of a building form. The form is the manifestation of architecture, and the initial insight into a form is figured out by observing its external shell. Therefore, the composition and the type of interactions of a shell with its surrounding forces determine the quality of this important element in construction. Evidence Acquisition: One of the most obvious patterns that have similar features with the outer shell of the building is the human skin, so the structural features of the skin can be used as a source of inspiration in production or improvement of the form’s outer shell. The skin is a vital and the widest living organ of the body. It is one of the most complex and active organs with such capabilities in transforming the human body as an efficient microclimate that can favor the situation of its internal organs and plays an important role in self-repair, energy absorption, and thermal insulation. Conclusions: In this study, we tried to use the structural features of the skin to provide suitable ideas for improving and upgrading the outer shell of the building form. Applying these capabilities in the structure of a building form would lead to the creation of a smart, usable, and expandable architecture with a favorable geometrical performance that will adapt to the surrounding environmental conditions, including climate, pressure, etc.
