Vývoj metodologické a technologické platformy pro neinvazivní odhad fenolických látek v listech a bobulích
ŠEBELA, David
Plant optical signals can serve as important source of information about biochemical and physiological processes in plants. These signals are influenced by compounds synthesized by plants during primary or secondary metabolism and thus, can also serve as their qualitative and quantitative indicators. Light reaching plant surface (leaf or fruit) can undergo three main pathways- it can be (i) reflected, (ii) absorbed or it can (iii) transmit through plant material. The probability of these three processes depends on particular wavelength of incident irradiation and on the morphological characteristics of plant tissues themselves. As such, plant contains various spectrum of photosynthetic pigments and fluorescent compounds which can either reflect, absorb or pass incident irradiation through at specific wavelengths. Biophysical techniques working with these optical properties of plant pigments and/or other compounds have become universal and common tool in basic and applied research. To quote some example, chlorophyll fluorescence imaging, UV induced fluorescence or spectroscopic techniques are on the top of interest thanks to its non-invasive nature, allowing maintain the integrity of measured cells or the whole plant constituents. The main aim of this thesis is to provide a comprehensive study on the possibility of non-invasive monitoring of phenolic compounds in the leaves and fruits.

History of critical and intensive care - past and present
HOVORKOVÁ, Nicole
The title of the bachelor thesis is "History of critical and intensive care - past and present". Its main aim is to describe its origins in order to explore the history of providing critical and intensive care, both in the Czech Republic and in a global context, and also in comparison to the current state of the medical field. This work is focused on the period of development of intensive care, from the 50s to the 80s. It is a theoretical work done by detailed research of secondary and primary sources. It is divided into two parts. The first is dedicated to intensive care and its global development and in the Czech Republic. The second part contains data about intensive care within the hospitals of South Bohemia, which I have gathered during the study of materials provided by the local archives. The first chapter and the second chapter is dedicated to the history of nursing, both worldwide and in the Czech Republic. It serves for better orientation in the next chapter. The third chapter deals with intensive care itself. It is described in many of its aspects and in its historical and global context. The fourth chapter brings us to the second part of the thesis, which is supplemented with information from archival materials found during the research in regional archives. The thesis includes some photos that were captured either during a visit to the Museum of the National Medical Library, or during visits to the archives.

A nursing issue: peripheral venous catheter
TOMÁNKOVÁ NOVÁKOVÁ, Monika
Peripheral venous catheter is used to access the venous system. It is one of the most commonly used invasive procedures in health care facilities. This procedure falls within the competence and daily tasks of nurses. Therefore this type of nursing care is susceptible to risk of proceeding routinely which might result in conscious or unconscious errors. Peripheral venous catheter needs to be introduced into the patient's vein in the following cases: planned parenteral nutrition, infusion or transfusion therapy, application of intravascular medication or contrast media, rehydration, blood sampling (which can be performed immediately after introducing the peripheral venous catheter and before administrating medication) and also during an emergency care for critically ill (such as cardiopulmonary resuscitation). Nurses should be as knowledgeable as possible about this issue so that the peripheral venous catheter can be introduced well and fulfil its purpose. It is important to ensure that nurses obtain all the necessary information about their patients before inserting the catheter and that they are able to properly inform the patients about the procedure and to communicate with them. Next, nurses should be familiar with the correct procedure for inserting catheters, they should be informed about possible contraindications and know how to choose the correct type of catheter as well as where to place it. Furthermore, nurses should care for this vascular access correctly and provide the patient with enough information about taking care of the catheter after the procedure. Finally, nurses should be aware of their own potential errors and also of possible complications. Therefore they should employ aseptic technique so that they can eliminate nosocomial infections. The thesis is divided into a theoretical and an empirical part. The theoretical part focuses on the history of peripheral venous catheters and their types, indications and contraindications, necessary equipment, nursing care, complications, etc. The empirical part consists of a research. The aim of the thesis was to map the use of peripheral venous catheters in hospitals as well as to identify factors that may lead to problems among the patients with peripheral venous catheters. Four research questions were assigned to these aims. 1. What is the procedure prior to inserting a peripheral venous catheter? 2. What are the standards of caring for patients with an inserted peripheral venous catheter? 3. In which steps of caring for peripheral venous catheters do the nurses lack knowledge? What equipment do the nurses prepare in order to insert a peripheral venous catheter? The Bachelor's thesis was conducted using a qualitative research survey. The methods of collecting data included semi-structured interviews and participant observations. The research was carried out only in one hospital ward and it was anonymous. First, the data were collected by means of a semi-structured interview. The nurses were asked 14 questions (see Appendix 8). During this interview, several more subquestions were added. The results of the interviews were then grouped into several categories for the sake of clarity. The second method of collecting data was participant observation. The observed facts were recorded into an observation sheet (see Appendix 9). The same nurses who were interviewed were also observed. This Bachelor's thesis has been written in order to provide a basic overview of the peripheral venous catheters. It could be used as an information source for more experienced as well as novice nurses. The practical output of this Bachelor's thesis is a nursing care standard concerning peripheral venous catheters. This standard was missing in the hospital ward and could help the nurses to take care of these vascular accesses, to proceed correctly and eliminate possible errors (see Appendix10).

The use of (nano)oxides for metal and metalloid stabilization in contaminated soils
Michálková, Zuzana ; Komárek, Michael (advisor) ; Luke, Luke (referee)
The main objective of the thesis was to evaluate the potential of selected Mn and Fe (nano)oxides for the stabilization of metals and metalloids in contaminated soils. The research was focused basically on three materials - commercial nanomaghemite (Fe III), nanomagnetite (Fe II,III) and a synthetic amorphous Mn oxide (AMO). The main aim of the work was to provide a complex view on the chosen stabilizing amendments regarding not just their direct influence on contaminants mobility and stabilization mechanisms, but also their stability and alterations in soil conditions together with influence on soil microorganisms and higher plants. Firstly, adsorption properties of the tested materials towards Cd, Cu, Pb and As were investigated. In this context, the most effective material showed to be the AMO reaching one to two orders of magnitude higher adsorption capacities than Fe III and Fe II,III under given experimental conditions. Interestingly, the rate of As(V) adsorption onto AMO was increasing with increasing pH as a result of high pHzpc of the AMO (8.1) and significant dissolution of this phase at lower pH values. As a next step, the influence of (nano)oxides on metal(loid)s mobility and other physico-chemical soil characteristics after application to contaminated soil was examined. Again, the AMO proved to be the most efficient in reducing mobile pools of Cd, Cu, Pb, Zn and As. On the other hand, Fe III and Fe II,III addition had generally less significant effects on contaminants mobility. AMO application further resulted in an increase of soil pH connected with AMO dissolution and unwanted decomposition of soil organic matter. When (nano)oxides alterations in soil conditions were observed, MnCO3 coatings were identified on AMO surface while no significant changes were recorded for Fe III and Fe II,III. As the MnCO3 formation was connected with increased AMO stability, AMO particles synthetically covered with MnCO3 coating (denoted as SM AMO) were prepared. Although the SM-AMO had a lower mass loss in soil than pure AMO, the stabilizing efficiency was almost the same for both materials. The differences in surface composition of both materials were decreasing with time as MnCO3 naturally precipitated on the AMO surface in soils while the SM AMO coating was gradually dissolving. When investigating the effect on soil microbiota, AMO efficiently promoted soil microbial activity while no significant changes were observed in the case of Fe III and Fe II,III. The AMO was also able to reduce the uptake of Cd, Pb and Zn by sunflower (Helianthus annuus L.), eliminate Zn phytotoxicity symptoms and increase biomass yield. On the other hand, toxic levels of Mn released from the AMO in an acidic soil were found in sunflower tissues. AMO application is thus recommended for contaminated neutral or slightly alkaline pH with a higher cation exchange capacity in order to avoid unwanted release of Mn. Finally, various types of AMO-biochar composite sorbents were recently prepared and field experiment focused on stabilization of Cd, Pb, Zn and As using studied materials is currently under preparation. The combined results from the thesis highlight the importance of a complex experimental approach dealing with all parts of the contaminated soil environment in order to obtain complete information about the efficiency and usefulness of any newly developed stabilizing amendment.

Clinical biochemical indicators used in diagnostics of equine diseases
Puldová, Doubravka ; Ptáčková, Zuzana (advisor) ; Krejčířová, Romana (referee)
The thesis aims to compile overview of main biochemical indicators that are important in for diagnostics of equine diseases.
Clinical biochemistry is a medical discipline that uses biochemistry and pathobiochemistry for the determination of diagnosis based on activity changes of analytes observed. Laboratory evaluation of analytes has three phases: pre-analytical (preparation of patient to sampling, sampling and sample storage and transport), analytic (analysis) and post-analytical (evaluation of results, veterinarian also contributes in this part). Pre-analytial phase is the most time consuming and also the most error prone. The errors mostly occur during preparation of the patient, during sampling or sample transportation. The most analyzed materials for biochemical analysis are blood, urine and liquor.
Biochemical indicators are compound that are often influenced by the disease, therefore it is possible to use them for the diagnosis. Nitrogen metabolism indicators include proteins, urea, creatinine and ammonia. Enzymes (aminotransferase, gama-glutamyltransferase, glutamatedehydrogenase, lactatedehydrogenase, alkaline phosphatase, creatinkinase and sorbitoldehydrogenase are the main indicators of liver function (they contribute on the metabolism of another compounds) or of the fitness of horse. Glucose and lactate values indicate energetic metabolism, cholesterol and triglycerides indicate lipid metabolism. Water and electrolyte metabolism indicators are sodium, potassium and chlorides. The mineral profile is shown by calcium, magnesium and phosphorus.
The result of determination of analytes is compared with reference values that are not only species-specific but can be also influenced by age or sex. These values represent the range of the compound concentration in body fluid under physiological conditions. It is important to take the clinical symptoms into the account. Not all indicators that are usually indicated in human medicine or different animals are suitable for diagnosis of equine diseases. Majority of indicators diagnose equine-rare diseases (i.e. diabetes mellitus or hepatitis). Determinations of muscle enzymes and lactate are important for the fitness analysis.

Feeding dogs the natural way
Beranová, Daniela ; Rozinek, Jiří (advisor) ; Libuše, Libuše (referee)
The bachelor thesis has the character of literary research. Focusing on feeding dogs the natural way. It is divided into several chapters.
The first chapter describes the digestive tract of the dog, its parts and operations which it provides. First described digestive system overall, and its importance for the body of the dog. The first part of the digestive system is the head portion, which include the mouth, including teeth, and pharynx. In the pharynx the digestive crosses paths with breathing. Epiglottis separates the head portion from the front intestine, which starts and continues through the esophagus into the stomach. It is connected to the small intestine, which parts are duodenum, jejunum and ileum. Small intestine enters the large intestine. It has three distinct parts: cecum, colon and rectum. Rectum narrows the anal canal, which ends anus. Further additives are described intestine organs and their functions. They are the liver and pancreas.
The second chapter focuses on the fact that the dog is a carnivore. Briefly summarized the emergence of dog domestication of the wolf and his digestive system, since it is still very similar. Changing digestion is a process that requires several hundred years. This section also describes what nutrients are important in the food contained a brief description. Another important part of the food is fresh water.
The third chapter is a division of commercially produced feed. They are divided according to water content and the method of preservation, according to the quality of raw materials and by ages, sizes and breeds workload. The next section summarizes the book by Dr. Hans-Ulrich Grimm. He is a journalist and author of several books that reveal the truth about industrial foods and certain brands in the industry.
The main part deals with the natural food for the dog. Is it a combination of meat, vegetables, fruits and sometimes other supplements, such as dairy products, cereals, herbs and much more. This chapter summarizes the advantages and disadvantages of feeding a natural food.
Finally, the work distinguishes the difference benefit the dog fed first industrially produced feed, then the natural food.
