Heat and mass transfer in the process of electrofractionation of secondary milk products

Paper presented at the 6th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 30 June - 2 July, 2008.Complete and wasteless processing of milk envisages a complex utilization and recovery of raw products, including secondary resources, taking into account ecological factors due to high indices of biological and chemical oxygen demand of whey. Electrical activation of whey is one of the promising methods of processing of secondary milk raw products that we have studied and used for recovery of protein-mineral concentrate, inversion of lactose into lactulose and their subsequent application. The working regimes of heat and mass transfer, characteristics of the obtained products and advantages of electrophysical treatment are described.vk201

The role of magnesium deficiency in the formation of functional constipation in children and adolescents

Pediatricians face a problem of functional constipation in children and adolescents in one-third of cases of observation. Functional disorders of the gastrointestinal tract are based on disregulatory processes of the cortical-vegetative-endocrine complex. Magnesium deficiency is one of the factors influencing the formation of functional constipation in children, and an important link in the pathogenesis of the disease. Correction of magnesium level by means of magnesium-containing mineral water is one of the safe, effective and complex factors influencing a number of pathogenetic mechanisms of formation of functional constipation in children and teenagers

Stress and stress-induced disorders in children

Stress is one of the main reasons for the exponential growth of most chronic non-infectious diseases. The stress response is a genetically determined nonspecific adaptive mechanism. However, if it is an overly intense and prolonged, it becomes a risk factor for the pathogenesis of cardiovascular and oncological diseases, immunodeficiencies, digestive tract diseases and other pathological conditions. Studies have shown that magnesium deficiency, which develops against the background of stress, repeatedly intensifies its negative manifestations. Magnesium preparations make up the basis of therapeutic and rehabilitation activities in children experiencing stress. Timely correction of magnesium deficiency can increase the resistance against the action of stressors, neutralize or mitigate their damaging effect, and also prevent the development of stress-induced pathology

Connective tissue dysplasia: a risk factor for osteopenia in children and adolescents

Introduction:  in addition  to genetic  predisposition,  a significant  exogenous  factor in the  formation  of Undifferentiated connective tissue dysplasia (UDCTD) is the deficiency of osteotropic micronutrients such as vitamins (D, A, C, E, K); macroelements (calcium, phosphorus, magnesium), trace elements (copper, manganese, zinc, boron, selenium, silicon), so essential for the connective tissue matrix and, above all, for bone tissue. A small number of studies of osteotropic micronutrients and the state  of bone tissue in adolescents with UDCTD served as the basis for this comprehensive study.Materials: a randomized  study of 130 adolescents aged 10–16  years in the 1–2  health  groups. The first group (primary) was 90 subjects with detected UDCTD. The second group (comparative) was 40 people  with no signs of dysplasia. Methods: included the definition of: vitamin D – 25(ON)D: trace elements; calcium ductation: spinal column densitometry at LII–LIV level; physical development and psycho-emotional stress levels.Availability disorders of 25(OH)D, low calcium consumption, magnesium  deficiency, and shifts in micronutrient content  correlated with densitometric data showing a 75% decrease  BMD in Group 1 adolescents, while in Group 2 only 27.5%.The results  of a comprehensive study showed  that  osteotropic micronutrient deficiency is a serious  exogenous  trigger  for the development and progression  of UDCTD with osteopenia/osteoporosis formation. Osteopenia/osteoporosis, low physical development, disorders in the psycho-emotional sphere  indicate the seriousness of the prognosis of UDCTD in adolescents

Vegetative dystonia in pediatric practice

The problem of vegetative dystonia in children and adolescents is relevant in view of the high incidence and risk of transformation into an organic pathology. According to most researchers, many serious chronic diseases have their roots in childhood and adolescence. This applies primarily to diseases of the cardiovascular system, such as hypertension or coronary heart disease in adults

Therapeutic mineral water: from past to future

The article presents historical materials formation and development of the source of mineral water Donat Mg (Slovenia), its unique properties, the study of which is not indifferent to several generations of scientists. Donat Mg is a mineral water, which has become a "bridge" linking researchers of the past and future generations, and leading to new findings
