Toxic compounds in a diet as a factor of chronic diseases
Logerová, Hana ; Dlouhý, Pavel (advisor) ; Černá, Milena (referee) ; Kouřimská, Lenka (referee)
Flame retardants have been used in the Czech Republic since the 1980s and 1990s as a part of the polymer matrix of plastic materials to decrease their combustibility and thus the risk of fire. Brominated flame retardants (BFR) are commonly used, polybrominated diphenyl ethers (PBDEs) are the most abundant flame retardants in plastic materials. The human population is exposed to these compounds particularly via diet containing fatty fish, meat and dairy products and via inhalation of dust particles. Another aspect is the duration of the exposure: it is known that human beings can be exposed to BFRs from infancy through prolonged breast feeding because breast milk can be contaminated by these compounds. This study was performed to investigate the concentrations of the main representatives of BFRs occurring in human adipose tissue and to compare these values with the concentration of chlorinated contaminants (PCBs, DDTs). The pollutants levels were newly measured in solid adipose tissue removed during surgery. A total of 107 samples of fat were taken from 19 - 76 year-old volunteers mostly obese women. A total of 16 PBDEs congeners were determined, of which only six occur in more than 38 % of fat tissue samples. The total PBDEs level attained an average value of 3.31 ng/g, which is 25 % less than was...
Microbiome of the human body and most commonly used probiotics by patients from pharmaceutical practice
Plíšková, Zuzana ; Rambousková, Jolana (advisor) ; Dlouhý, Pavel (referee)
This work is divided into theoretical and practical. Theoretical part discusses human microbiome, probiotics, prebiotics and synbiotics. Beginning work describes the human microbiome, as a living ecosystem consisting of several hundred species of microorganisms, its development from birth to adulthood, for proper functioning of all organ systems including the skin. Normal microbial flora prevents the body against infection, re-creates health and serve as an example to prevent traveler's diarrhea. In cases which cause reduction in the number of microorganisms (constipation, diarrhea, antibiotic therapy, and others), the body needs help using probiotic products, usually in the form of capsules, for the faster restoration of the normal microbial flora. It is important to choose a formulation which is suitable for the chosen target - that is, select whether purely probiotic or prebiotic agent combined with differently therefore termed synbiotic. Practical part deals with statistical data processing of the sales of probiotic products for a period of one year and determines the trend of sales. The results show seasonal marketability, probiotics, when it occurs more in the summer months. To demonstrate higher sales of probiotic products was used to compare data from 2012 and 2017 from a pharmacy Mlada...
Content of mono and disaccharides in soft drinks and their health impact.
Haurová, Anna ; Hrnčířová, Dana (advisor) ; Dlouhý, Pavel (referee)
Carbohydrates are an integral part of human diet. We distinguish them according to their length, usability, glycemic respond and taste. Sugars are mainly found in sweetened beverages and processed food. Consuming empty calories in the form of sugar sweetened drinks leads to the recommended daily allowance of sugars and total energy intake is being exceeded. It has negative impact on risk of civilization diseases like obesity, type 2 diabetes mellitus, dental carries and depression. Limiting the intake of sweetened beverages and industrial processed foods, principles of healthy diet and enough of exercise helps to prevent these diseases.
Problems of supplementary food sales in schools and school facilities
Šašková, Klára ; Dlouhý, Pavel (advisor) ; Rambousková, Jolana (referee)
This bachelor's thesis deals with the issue of the complementary sale of food products in schools and school facilities, which is, at the moment, regulated by the appropriate statute (the Decree No. 282/2016 Coll., on requirements on food products for which an advertisement is allowed and which can be offered for sale and be sold in schools and school facilities). In the theoretical part of this thesis, the contemporary legislation on the subject-matter is described first. A brief chapter is dedicated to school meals. Subsequent chapters are devoted to requirements set for child food and the question of technological opportunities for food modification. The underlying goal of the theoretical part was to raise awareness of the contemporary alarming state with a growing trend of the obesity occurrence and to provide the reasoning why an emphasis on a proper food, especially during childhood, is so essential and, consequently, why a certain level of legal regulation in this field is desired. In the practical part of this thesis, food products, which satisfy the requirements set forth by the Decree No. 282/2016 Coll., were searched for. The results were projected into tables and they were verbally evaluated in the form of a discussion and they were compared with the requirements, which are now set forth...
Prevention of postural defects in the population
Langmajerová, Jana ; Müllerová, Dana (advisor) ; Novák, Jaroslav (referee) ; Dlouhý, Pavel (referee)
This dissertation aims at verifying methodology used for somatographic evaluation of the shape and statics of the spine. The potential of the methodology verified lies in increased objectivity of upright body posture evaluation and thereby contributes to the specification of preventative measures for postural defects, and their consequences. Under a cross-sectional pilot study, a non-invasive somatographic method-a diagnostic DPT-3 system designated for spine shape diagnostics-was used to examine selected biomechanical parameters (spinal curves and statics in the sagittal plane in the upright position) in a total of 508 probands. Of this, 326 were school-age children and 182 adults. Among the key parameters monitored were: Cl (depth of cervical lordosis); LI (depth of lumbar lordosis); the sagittal balance of Cl/Ll, and VThk (distance of the peak of the thoracic kyphosis from the ideal verticals-IV). A questionnaire was used to evaluate the level of movement activity in probands and the relation between the occurrence of painful back and headaches and the measurement of biomechanical parameters and movement activity. A total of 81.3 % of children and 94.5 % of adults were found to have deviations from the biomechanically ideal posture model, which signals a postural defect. The values of the Cl (p...
