The process of generating the vast diversity of immunoglobulin receptors and secreted antibodies begins with the recombination of the joining (JH), diversity (DH) and variable (VH) genes in the immunoglobulin heavy chain locus. The ability to produce antibodies is restricted to the B cell lineage and is tightly regulated, starting with the temporal separation of the recombination process, in which DH-JH precedes VH-DHJH recombination. Successful recombination of both heavy and light chain loci results in the expression of an antigen receptor on the cell surface. Subsequent selection stages remove non‑functional and autoreactivity receptors from the final pool of antigen responding B cells that ultimately give rise to antibody secreting plasma cells. Understanding the complexity of the recombination processes and the diversity of the resulting antibody repertoire has been a major focus of academic and industrial research alike. Therapeutic monoclonal antibodies have seen many successful applications within the clinic and they constitute a billion-dollar industry. However, limitations therein have resulted in the emergence of antibody engineering approaches and the use of natural sources of alternative heavy chain only antibodies (HCAbs/nanobodies). The biotechnology company Crescendo Biologics has taken the highly desired characteristics of HCAbs a step further with the creation of a mouse platform capable of producing fully humanized HCAbs. The Crescendo platform presents a unique opportunity to expand our understanding of how mouse B cell development functions by exploiting the features of heavy chain only antibody production. Furthermore, the platform enables the expansion of our limited knowledge of the epigenetic mechanisms involved in the recombination of the human immunoglobulin heavy chain locus. Using flow cytometry, with dimensionality reduction analysis approaches, I investigated B cell development in the context of HCAbs. These studies revealed a previously uncharacterised developmentally intermediate B cell population. Due to ethical and availability limitations to studies of human bone marrow, the primary pre-selection human B cell repertoire has not been studied in detail. The isolation of several B cell developmental stages and the use of our novel DNA-based high-throughput unbiased repertoire quantification technique, VDJ-seq, allowed me to study recombination of the human IGH locus sequence and observe HCAb repertoire selection within the mouse environment. The adaptation of next generation sequencing techniques to antigen receptor repertoire quantification has provided an unprecedented insight into repertoire diversity and the alterations it undergoes during infection or ageing. Our VDJ-seq assay is unique in its ability to interrogate DNA recombinants. To expand its capabilities, I investigated several limitations of the technique, including mispriming and PCR/sequencing errors, and implemented experimental and bioinformatics solutions to overcome them, which included the creation of a comprehensive analysis workflow. Finally, I have developed and applied a novel network visualisation method for genome-wide promoter interaction data generated by promoter capture Hi-C. The availability of high quality human pluripotent stem cell datasets allowed me to utilise the new techniques to further our understanding of the dynamics of genome organisation during early human embryonic development. This visualisation approach will be directly applicable to understanding B cell development.

This thesis is focused on occurrence of viral hepatitises by clients in Psychiatric Hospital Červený Dvůr between 2000 and 2009. In my beachelor thesis was covered years from 2000 to 2004. Now I continue with this diploma thesis where I want the 10 year results join together to show how the situation is developing. The intravenous drug users are the aimed group. These drug users belong to a high-risk group in which hepatitises types A, B or C are spread the most thanks to their high-risk behaviour. These days researches and epidemiologic researches show that the intravenous drug users belong among the main high-risk groups endangered by infectious disease. Viral hepatitises represent a serious problem, mainly hepatitis type C, because there is no way of protection. This hepatitis is occuring without any symptoms of this disease by 50 ? 70 % people. By 70 ? 80 % it passes into a chronic stadium. It is possible to protect yourself by hepatitis type A vaccination. This hepatitis doesn´t change into a chronic stadium. It is easily spread by infected water or food. In our republic there occured several epidemics. Hepatitises started to spread among drug users and then they spread also among the rest of population. The last epidemic occured in 2008. Hepatitis type B represents high risks for the perceptive population. There is a vaccine and population have a chance to protect against it. In the Czech Republic there is vaccination carried out within special vaccination of people who have high-risk job, for example in health service. Children of HBsAg positive mothers are vaccinated after they are born. From 2001 hepatitis vaccination was put into regular vaccination of children aged under 1 year in our republic. Also 12 year old children are vaccinated from 2001. Hepatitis type B often becomes chronic and the mortality is 1 ? 2 %. Intravenous using of drug is important high-risk factor. It is one of the ways of transfering hepatitises type B and C. Next monitored indicators are the age of the clients, achieved level of education, basic drug, the age of the first usage of any drug, the age of intravenous application of drug and occurrence of hepatitises type A, B, C by clients. According to my research I used quantitative research which allows me to analyse problem of viral hepatitises by clients from Psychiatric Hospital in Červený Dvůr. The gained information was worked out by secondary analysis of medical data. The monitored group has 2499 clients in years 2000 ? 2009. The aim of this thesis is to get general knowledge about prevalence of viral hepatitises by clients of Psychiatric Hospital in Červený Dvůr from 2000 to 2009 and to consider their progress. The methodical procedure: there will be used a content analysis of medical data given by Psychiatric Hospital in Červený Dvůr. The result of this thesis is that it indicates and covered the develop of drug scene. Concerning the age the main group consists of 20 ? 24 year old men and women, next large group consists of clients aged 25 ? 29. The monitored group is also changing according to achieved level of education. In the first five years of research there dominated vocational school, but in the last five years there it changed into basic school. Among women there happened no change. There basic school still dominates. Concerning the drugs there also changed something. At the beginning there dominated clients using heroin, in the middle there meth dominated. Hepatitis type A in acute stadium was revealed by only two clients. Hepatitis type B noticed a slight increase. Hepatitis type C also noticed a sligh increase, but it is probably a sign of increase of clients with chronic form of this hepatitis.

Diabetes mellitus is considered as one of world's most common metabolic diseases. Complicated treatment and increasing number of newly diagnosed patients, suffering from diabetes every year, shows the importance and necessity of research in this area. Some of the major aims of this research are the development of new therapeutically utilized drugs and defining the problems of insulin acting in human body. Insulin is a peptide hormone whose main physiological function is to regulate blood glucose level in organism connected with large impact on whole metabolism. Insulin acts through binding of its monomeric form to the insulin receptor. Upon binding to the receptor molecule of insulin undergoes specific structural changes, which put the hormone into an active state. As of now, the structure of the insulin's active monomeric form is still unknown. By testing binding affinities of many modified insulin analogues there was discovered strong evidence between structural conformation of the C-terminus of the B-chain and binding affinity to the receptor. The most crucial data, necessary for this work, were observed from the structure of highly active insulin analogues that possessed unique B26 turn, recently prepared and described by team of Dr. J. Jiráček, IOCB AS CR. The aim of this work was synthesis of...

In un mondo in cui la preoccupazione per l’equilibrio ambientale è sempre più pressante, la rifessione sul rapporto tra spazio urbano e spazio agricolo – e, in particolare, sulle modalità di approvvigionamento delle città e, più specifcamente, sul il commercio alimentare – diventa evidente. L’analisi dello stretto rapporto tra commercio e trasformazione urbana nella città di Lisbona, così come, in particolare, Marvila – un quartiere appartenente alla parte orientale di Lisbona dove, fno a tempi recenti, proliferavano fattorie e orti – ci serve come pretesto per ripensare al ruolo della produzione agricola e del commercio all’interno della struttura cittadina. Attraverso un’analisi dello stretto rapporto tra commercio e trasformazione urbana, si cerca di prevedere come un commercio basato su fliera corta possa trasformare profondamente il modo di vivere dei suoi abitanti. Il carattere frammentato e disperso del territorio di Marvila ci aiuta a immaginare la città alla luce delle infrastrutture che potrebbero trasformare Lisbona in un sistema.

Before 1891, it was commonly accepted that the most important source for the rule of the Four Hundred in Athens in 411 BCE was Thucydides' description. The situation changed thanks to the publication of the Aristotelian treatise On the Athenian Constitution, whose version of events differed markedly from Thucydides' one. There followed many attempts at determining which of the two versions was most reliable, or at combining the two versions. These controversies are the focal point of this thesis, but its ambitions are not limited to them: its ambition is also to reconstruct the chronology of the rule of the Four Hundred as precisely as is possible in context of the Peloponnesian war; and to formulate the limitations that are imposed on us by the character of sources at our disposal. Continuity of the coup with earlier developments and its impact on subsequent events are dealt with more briefly.

This study proposes a measurement and assessment model for the construction productivity of freeway reconstruction project, according to on the previous studies of Thomas and the characteristics of the freeway reconstruction project. The model is used on the cases of the freeway No. 1 reconstruction projects and No. 2 new construction project in Taiwan to realize and compare their respective influence factors of the construction productivity. When the model evaluates the threshold construction productivity of the embankment in the cases, the estimate values for the reconstruction projects and the new construction project are 0.048~0.052 MH/ M 3 and 0.025 MH/ M 3 , respectively. In addition, the influence factors in the reconstruction projects and between the reconstruction projects and the new construction project are introduced, leading to the arrangement of improvement methods. The results based on this study can support the use of the model to various constructions to completely establish the threshold construction productivity in construction engineering for the further use of the cost analysis and construction management. The working content factor in the model, however, should be further studied in a future to obtain a better result.

Cymbopogon citratus (DC). Stapf (Poaceae), commonly known as lemongrass, is a tropical perennial shrub originated from the Southeast Asia. This plant is reported to possess antifungal, insecticidal, anti-diabetic, anti-septic, anti-mutagenic, anti-carcinogenic activities as well as anti-inflammatory. In fact, aqueous extracts of dried leaves are used all over the year in folk medicine for the treatment of peptic ulcers and inflammatory conditions. Recently, some phenolic compounds, such as luteolin and apigenin glycosides and condensed tannins, were identified and related to both antioxidant and anti-inflammatory properties. The purposes of this work were to i) validate an analytical method for quantification of phenolic compounds of C. citratus; ii) study the influence of harvest time and plant quality on the phenolic composition and antioxidant activity; iii) characterize the tannins; iv) validate the traditional uses of lemongrass infusion as anti-inflammatory in vivo; v) obtain a topical formulation to evaluate the phenolic compounds permeation and their anti-inflammatory activity; vi) trace the pharmacokinetic profile of the main phenolic compounds in rats. Three different extracts: infusion (CcI), 50% aqueous ethanol (CcM50%) and ethanol (CcM100%) extracts were prepared and a simple and efficient RP-HPLC-PDA method was successfully validated for simultaneous identification and quantification of phenolic acids and flavonoids. Infusions were also obtained from different harvest dates (April, June, July, August and September) and quality grades (High, Medium and Low). It was verified that the content on polyphenols and the antioxidant capacity of CcI is strongly related with the quality of the plant. The total phenols assay showed a substantial loss from August to September. It was possible to find out the best month to harvest the plant to get the most of each phenolic group: April and June for hydroxycinnamic acids; June and September for flavonoids; June, July and August for tannins. Regardless the group of phenolic compound addressed, its content was always inversely proportional to the degree of leaves ageing. For all tested oxidant species, the high-quality samples exhibited the best antioxidant results. CcI was fractionated by column chromatography and polyphenol-rich fractions, namely phenolic acids (CcPA), flavonoids (CcF) and tannins (CcT) were obtained. CcT was characterized by HPLC-PDA-ESI/MSn, revealing the presence of proanthocyanidin hetero-dimers, along with some common procyanidin dimers. These hetero-dimeric flavan structures have been described for the first time in lemongrass and consist of apigeniflavan or luteoliflavan units linked to a flavanone, either naringenin or eriodictyol, and may occur as aglycone or glycosylated forms. For the in vivo assays, CcI, CcF and CcT were tested. CcI administered before and after ethanol stimulus, significantly reduced the incidence and severity of gastric lesions and, consequently, the ulcer index, corroborating the traditional medicinal use of this plant to ameliorate gastritis and/or peptic ulcers symptoms. On the other hand, CcI, CcF and CcT were orally administered to rats, in order to evaluate the anti-inflammatory effect at the carrageenan-induced paw edema assay. The observed effect by CcI (68.24 mg/kg), 82.30% of edema inhibition, was very similar to that obtained by the reference NSAID used (diclofenac, 10 mg/kg), 84.00%. On the other hand, flavonoid (7.42 mg/kg) and the tannin-rich (5.96 mg/kg) fractions significantly contributed for the anti-inflammatory activity on the edema volume (59 and 61%, respectively). The topical anti-inflammatory activity of CcI was also addressed. The results suggest that flavonoids, mainly, luteolin 7-O-neohesperidoside, cassiaoccidentalin B, carlinoside and cynaroside, may contribute to the topical anti-inflammatory effect. CcF (0.6%), CcT (0.3%) and CcF+CcT (0.66%+0.34%) topical formulations were also tested, and the results obtained suggest that tannins and flavonoids also possess a significant activity and that a synergistic mechanism of action may occur. In fact, edema inhibitions of 43%, 47% and 59% were respectively verified, being CcF+CcT effect very close to that of 1% diclofenac (65.9%). Pharmacokinetic analysis was performed in plasma, liver and kidney and showed that the compounds present in CcI are not detected in vivo after a single-dose oral administration. In contrary, the metabolites, luteolin 7-O-glucuronide and luteolin 3’-O-sulfate, present at the highest bioavailability, are probably the main responsible for the anti-inflammatory activity previously reported. In conclusion, this work has developed a method to quantify the phenolic compounds contained in C. citratus; pointed the importance of harvesting and storing the plant material, in order to take the maximum advantages from the phenolic compounds use; and demonstrated, in safe doses, its anti-inflammatory activity, using an in vivo approach, which supports the traditional use of lemongrass infusion. Furthermore, C. citratus leaves flavonoids and tannins were highlighted as bioactive compounds, encouraging the development of new anti-inflammatory drugs or nutraceuticals.
