Determination of volatile isoprenoids as water stress markers of spruce resistance against bark beetle
Slušná, Michaela ; Kalinová, Blanka (advisor) ; Hoškovec, Michal (referee)
Isoprenoids are important components of conifer resin and represent an important part of constituted defence system against herbivores and pathogens. Drought is one of the most important factors that influences the tree physiology and resitance. Due to decreased turgor of resin canal cells, the water insufficiency affects the pressure of the resin and thereby the ability of trees to physically prevent pathogen or herbivore invasion by effective outpouring of the resin. In addition, drought can also change the resin composition and thus can influence the quality of volatiles emitted by the tree. The Norway spruce, Picea abies, is the predominant species of production forests in moderate climate zone. Bark beetles, Ips typographus, represent the most important pest species of spruce. In general, pioneer bark beetles use host volatiles to orient themselves toward the tree suitable for colonization and in many species host volatiles synergize bark beetle aggregation pheromones. Thus the host volatile composition could affect significantly host colonization. This diploma thesis studied the influence of drought on the production and composition of isoprenoid volatile organic compounds in 80 - 100 years old spruce trees. Using I. typographus antennae as biological detectors, we also studied which resin...

Clinical importance and mechanisms of action of morphine and methadone
Slušná, Michaela ; Novotný, Jiří (advisor) ; Hejnová, Lucie (referee)
This bachelor thesis deals with gathering the information regarding the clinical importance of opioid drugs, particularly morphine and methadone, and their mechanism of action. Awareness of health professionals and the general public on opioid is inadequate. This evokes unnecessary anxiety of uninformed patients by the treatment of this kind of drugs. This thesis contains information that should know each worker in the health sector. It deals with pharmacodynamics, which is important for understanding the effects of drugs, both biochemical and physiological as well as pharmacokinetics, which describes how the body compensates for the delivered drug. Usage of morphine and methadone is currently irreplaceable. Morphine is a strong analgesic effective control of pain of different origin. Methadone is used for the substitutive treatment of people addicted to opioids. The side effects occurring during the treatment with opioids are acceptable with regard to severe pain, which is attenuated by opioids.
