Mobile Application for Overcoming Dopamine Addiction
Balušeskul, Adam ; Kapinus, Michal (referee) ; Chlubna, Tomáš (advisor)
The aim of this thesis is to create a mobile application that helps the user get rid of the constant intake of dopamine and addiction to it. This brings in most cases several positive changes, such as strengthening internal motivation, improving concentration and building discipline. The solution is designed using gamification to make completing tasks that help cultivate healthy habits fun and motivating, so that the user wants to continue. The application provides several functionalities. It gives the user the opportunity to learn about the brain and dopamine and measure detox time using a timer. The user’s rank is increased after achieving various goals in the application. For completing these goals, the user is also rewarded with achievements. Motivating users during detoxication was successfully achieved by implementing game elements into the application.

Placental transport of dopamine and norepinephrine
Turková, Helena ; Štaud, František (advisor) ; Jirkovský, Eduard (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology & Toxicology Student: Helena Turková Supervisor: prof. PharmDr. František Štaud, Ph.D. Title of diploma thesis: Placental transport of dopamine and norepinephrine During the whole course of pregnancy, it is important to maintain proper monoamine homeostasis, namely serotonin (5-HT), norepinephrine (NE), and dopamine (DA), which are crucial for proper placental function and fetal development. Monoamines are important neuromodulators, involved in cell proliferation, and differentiation. and neuronal migration. High fetal monoamine secretion during gestation demands a responsible clearance mechanism, as disruption of their balance may lead to long-lasting changes in brain structure and function, provoking a higher risk of attention deficit hyperactivity disorder (ADHD), autism or depression. However, uptake of NE a DA through the fetoplacental unit has not been fully and in detail described. Therefore, in this diploma thesis, we focus on the uptake of NE and DA through ex vivo isolated vesicles of microvillous (MVM) and basal (BM) membranes from healthy human term placentas. Our results show that NE and DA uptake is mediated via high-affinity and low-capacity serotonin (SERT) and norepinephrine (NET) transporters in...

Possible association of polymorphisms in COMT gene with mental diseases
TOMANOVÁ, Aneta
This thesis i focused on associacion of polymorphisms in COMT gene with mental diseases, primarily on polymorphism Val158Met. The theoretical part provides definitions of COMT gene and enzyme, catecholamines affected by COMT and definition of the polymorphism Val158Met. Next is listing of mental diseases, description and known connection with researched polymorphism. The practical part contains proceeding of PCR RFLP used to detect the genotype. The results were evaluated and connected to the theoretical part of the thesis.

The effect of a regular exercise on the health of patients with Parkinson´s disease
DUBNOVÁ, Veronika
The bachelor thesis deals with the influence of regular exercise on the health of patients suffering from Parkinson's disease. This disease still remains an incurable disease that affects the human central nervous system and leads to its irreversible damage. Until now, the treatment of the disease has only made it possible to alleviate individual symptoms in the long term and thus maintain the patient's quality of life. An important part from the early stages of the disease is not only a pharmacological treatment but also a rehabilitation. The theoretical part of this work deals with a summary of information about Parkinson's disease, its origin, clinical picture, diagnosis and treatment options. The practical part of the work was processed by the method of qualitative research, which was done on the basis of an input and output examination, medical history taking, an interview and an evaluation of patients' ability to walk. The obtained data were compiled in the form of case reports. The study group consisted of 3 patients with a diagnosis of Parkinson's disease, who regularly attended group exercises once a week. The first goal was to evaluate the patient's condition during regular group exercise and the condition after 8 weeks without a group exercise. The second goal was to create an exercise unit for patients suffering from Parkinson's disease. Due to the small number of probands studied, it is certainly not possible to state whether the regular exercise once a week was sufficient in the treatment of Parkinson's disease. However, it was obvious that the patients felt good during the exercise, it positively affected their psychosocial condition and also their condition. Although I did not come to clear conclusions, I presume that the chosen therapy was beneficial.

Molecular mechanisms engaged in the development of drug addiction
Pallag, Gergely ; Novotný, Jiří (advisor) ; Nerandžič, Vladimír (referee)
Drug use is part of the human life from the ancient times. Besides their recreational utilization, sustained misuse of these substances can lead to the development of drug addiction especially in susceptible individuals and thus cause serious health and social problems. The aim of this thesis is to briefly introduce brain structures which are affected by addictive substances, and describe some of the mechanisms and molecules that contribute to addiction. A crucial brain structure which plays a role in drug addiction is the reward system, with dopamine as the main neurotransmitter. After repeated use of drugs, in neurons of this system certain molecules and epigenetic changes are accumulating that promote chronic nature of addiction. Especially important is the highly stable transcription factor ΔFosB, which in cooperation with other molecules promotes relapse even after several months or years of the last drug use.

Molecular dynamics simulations of biomolecules
Naništa, Ján ; Barvík, Ivan (advisor) ; Bok, Jiří (referee)
This study deals with classical molecular dynamics simulations of time evolution of a biomolecular system. The simulated system consists of the D3 GPCR membrane receptor for dopamine surrounded by a cell membrane and covered with water molecules and ions. The aim was to analyze the ability of Eticlopride to bind into the active site of the GPCR receptor.

Effect of cholinesterase inhibitors on monoaminergic system and energic metabolism
Kalinová, Tereza ; Mladěnka, Přemysl (advisor) ; Štěpánková, Šárka (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology & Toxicology Student: Tereza Kalinová Supervisor: Assoc. Prof. Přemysl Mladěnka, Pharm.D., Ph.D. Mentor: Assoc. Prof. Jana Hroudová, Pharm.D., Ph.D. Title of diploma thesis: Effect of cholinesterase inhibitors on monoaminergic system and energy metabolism Cholinesterase (ChE) inhibitors play an essential role in the treatment of Alzheimer's disease (AD). They effect positively cognitive, functional and behavior symptoms of AD. Up to date, donepezil, rivastigmine and galantamine represent the only ChE inhibitors approved for AD treatment. The first ChE inhibitor was tacrine, which was withdrawn from market due to its toxicity and adverse effects. Recently, novel tacrine and 7-methoxytacrine (7-MEOTA) derivatives were synthetized and extensively investigated to find less toxic compounds affecting pathological mechanisms associated with development of AD. There is less known about effects of these drugs on mitochondrial functions and cellular energy metabolism. The aim of this project is to examine in vitro effects of ChE inhibitors on energy metabolism and cellular respiration, specifically on mitochondrial electron transport chain complexes and an enzyme of the citric acid cycle - citrate synthase. Inhibitory effects...
