Transport systems used in cosmetics
Škopová, Jitka ; Kramářová,, Daniela (referee) ; Zemanová, Jana (advisor)
Between transport systems in cosmetics belong liposomes, liquid crystals and also chosen substances, which speed under given conditions a transport of active compounds, so-called accelerators of trans-dermal penetration. Liposomes are used topically (i.e. directly onto the place of their action in surface structures of organism) in dermatological and cosmetic preparations, they facilitate the penetration of active substances into the deeper layers of the skin and make possible their more expressive treatment. Some properties of liquid crystals are similar to the properties of live organisms. Analogous to the vital cells are they sensitive to light, sound, warm, mechanical straining and chemical changes. And by contraries, some scientists mark vital cells as liquid crystals. Thanks to this similarity are liquid crystals characterized by their excellent ability to penetrate by the skin, which is probably comparable only with liposomes. Accelerators of trans-dermal penetration otherwise accelerators of penetration by the skin are substances, which change structure of the skin or derma to be more permeable for other compounds. The trans-dermal penetration of active substances is an important part of medical researches. Those results are however applied also in other branches as for example is cosmetic industry. From the point of view of the chemical texture of these materials form they a very heterogeneous group and an elucidating of mechanisms of their incidence is so far rather in beginnings.

Kidney Transplantation in Theological-Ethical Reflexion
Zárubová, Jaroslava ; Milfait, René (advisor) ; Vlková, Eva (referee)
In my diploma work i tried to valued transplant in a christiant (religious) point of view. My essay (diploma work) is consisit of (devided to) two parts - medical part, in which I have written about individual steps made before the exact transplant and I also explained what are the benefits and negatives of transplant. In the first part I also included law issues of transplant in Czech legislation, about the difficulty to donate the organ, perhaps the risk of the individual donors. I described the criteria of death from medical and ethical point of view. In a second part(teological) I have written about the value of the transplant from the ethical point of view, the religious side (reflexion) it means till when the human being is still considered as a person whose dignity has to be (needs to be) respected and whether the human autonomia is the ethical password. From the religious point of view (side) does not exist objection against volunteery transplant donors. Donor transplant is morally accepted with agreement of the donors themself and without excessive (enourmous) risks included. The purpose of th death of the individual is diagnosed (found out) first before the transplant can be donated. The possibility of the donation (transplant) abuse is the organs selling market. In the christian way the life is...

HPLC separation of p-aminophenol, paracetamol, caffeine and propyphenazone on polar stacionary phase.
Maroušková, Alena ; Sklenářová, Hana (referee) ; Šatínský, Dalibor (advisor)
This thesis deals with finding optimal chromatographic conditions for a separation of p- aminophenol, paracetamol, caffeine and propyphenazon by HPLC. These analytes have different polarity and acidobazic properties. The application of traditional octadecylsilane stationary phases for their simultaneous determination is problematical. The PEG column have proved to be suitable for an efficient separation of the analytes with different polarities, i.e. with different chromatographic behavior. The resulting method brings shortening of analysis time, which is important for analysis of big series . Within the optimization of chromatographic conditions: a wide range of mobile phases has been tested (various organic solvents, various ratio of organic components to water phase components) a various level of acidity of the mobile phase has been tested ranging from 4 to 7 pH units various buffers have been tested behavior of the analytes has been tested under an enhanced temperature two PEG columns with different lengths have been tested Optimal chromatographic conditions for a separation of the analytes mentioned above, as well as the fulfillment of requirements for simplicity, analysis time and high degree of reliability have been found. The final chromatographic conditions: Stationary phase:...

Comparison of coordination and condition abilities of young karate youth and the other school youth
Kesner, Petr ; Venzara, Jan (advisor) ; Chytráčková, Jitka (referee)
Title: Comparison of coordination and condition abilities of young karate youth and the other school youth. Goals: To compare level of coordination and condition abilities by three groups of probands from the same place of a small town, where the first group regularly attends Kyokushinkai trainings, the second group regularly sports and the third group does not any sport in any sport club. Methods: The whole group was divided into 3 subgroups: sportsmen, who have trained fullcontact karate - school of Kyoukushinkai, sportsmen, who do actively any sport (football, floorball, table tennis, et.) and youth, who do not any organized sport activity. I measure the motory efficiency by the UNIFITTTEST (6-60) and level of coordination abilities by project of Kohoutek et. (2005). Results: It was proved that regular sport activity has a positive influence to a condition and coordination ability. Also it was proved that youth practicing regular trainings of martial arts of Kyokushinkai karate have higher level of tested motory abilities than their school mates who practice other organized sport. It is obvious that karate training and other sport activities have a positive influence to a motory ability level. I consider karate training to be a sport which develops complexly coordition and condition...

Mediální prezentace veřejné zeleně v Českých Budějovicích (obsahová analýza jihočeského regionálního tisku)
Kušová, Drahomíra ; Těšitel, Jan ; Bartoš, Michael
Press is a part of mass communication providing the public with information and symbolic contents. It always reflects the supposed interest of the public in concrete problems and it mediates social control of the institutions which are responsible for the particular spheres. On the basis of the content analysis of the regional press in South Bohemia we can state that citizens do not perceive the problem of public greenery as urgent and thus this topic is not very frequent in the media. People mainly observe if public greenery is in good shape. The number of organisms to be encountered in urban environment by greenery users is not large according to the press.

Diving diseases
Rejdovjan, Simon ; Hrnčíř, Evžen (advisor)
This thesis mentions the basic physiological and physical principles of diving, it deals with diseases and injuries that occur in the connection with diving. The diseases are divided according to the phase of the diving as follows: The diseases originating from the change of surrounding pressure, diseases connected with staying in the depth and diseases stemmed after emersing above the surface of the water. Deeply elaborated chapter about Decompression disease includes a scale of predispositioning factors to this disablement. Next it mentions diseases that are not connected with the change of surrounding pressure. This part of my thesis describes the different forms of poisoning by enhaled gases, infectious diseases, drowning, hypothermia, hypoxia and it also includes an extended chapter that deals with sea animals and their potentional danger for human organism. The work also references to some preventive processes which can minimalize the risks of occurence of these diseases and injuries.

Prevention of Cervical Cancer
Kafková, Simona ; Šafář, Petr (advisor)
Cervical cancer is a disease characterized by an abnormal growth of cells in the uterine cervix. It is caused by an infection with a range of high risk oncogenic human papillomavirus (HPV) and it is now accepted that more that 99 % of the cervical cancer is initiated by the HPV infection. HPV is the most common sexually transmitted viral disease. Most of the HPV infections are only temporary and human organism can destroy the infection with its own immune response. A persistent infection can lead to the malign transformation and an uncontrolled cell proliferation. There are more than 10 years between an epithelial infection and cervical cancer. Prevention of cervical cancer includes an HPV protection, an early diagnosis and a treatment. In spite of the fact that there has been enormous progress in the area of the cervical cancer prevention when vaccination against the most common HPV types was discovered, an early precancerous diagnosis through the use of the full-area screening still remains an essential precaution. The screening still needs to be provided not only to unvaccinated women but also to the immunized ones because current vaccines protect only against 80% of the oncogenic HPV types. Because of the prolonged absence of clinical symptoms in precancerous stages, the cytodiagnosis is the only method...

Influence of storage conditions on content of biologically active substances in apple fruits.
Ferdová, Jitka ; Čarnecká, Martina (referee) ; Márová, Ivana (advisor)
This study deals with antioxidants in diet and their effects on human organism. Further, it summarizes the agents affect the quality of apples in the course of long-term storage and it outlines the possibility of defence against them. In the experimental part methods of determination of antioxidant enzymes superoxid dismutase (SOD), catalase and polyphenol oxidace (PPO) in apples were introduced. The enzymes were measured in apples tissues in liquid nitrogen after 158 days in normal or modified atmosphere. In Apple the quantitative and qualitative analysis of proteins was realized. Further, some low molecular antioxidants (total phenolics, total flavonoids and vitamin C) as well as total antioxidant status were measured in frozen raw juice. This values were compared with values from apples analyzed immediately after the harvesting. Artificial inoculation with fungi was made in the last part and the fruitfulness was observed.
