Produkce a zpracování drůbeže v české republice
SIAWELA, Saviour
2022 - English
Cílem bakalářské práce je porovnat a porozumět produkčním a zpracovatelským opatřením kombinace rodičů brojlerů a jejich potomků pro žádoucí typ chovu pro komerční chovatele brojlerových kuřat COBB 500 a ROSS 308. Údaje byly získány z Mezinárodního testování drůbeže, státního podniku v Ústrašicích. Testování rodičů hybridů COBB 500 a ROSS 308 se sestávalo z období odchovu rodičů do věku 154 dnů a snášky. Byly provedeny dva výkrmové testy ukončené ve 35 dnech, resp. ve 42 dnech. Výsledky testů naznačily, že kuřata ROSS 308 vykázala vyšší živou hmotnost ve srovnání s kuřaty COBB 500 v období odchovu v rodičovském testu. Nižší spotřeba krmné směsi byla realizována u hybridů COBB 500 v tomto období. Kromě toho byla pozorována nižší spotřeba krmné směsi na den u hybridů COBB 500 během období snášky. Vyšší počet vajec byl vykázán u slepic ROSS 308, ale počet vylíhlých kuřat na 1 nosnici byl vyšší u slepic COBB 500. Vyšší živá hmotnost a nižší spotřeba krmné směsi na 1 kg přírůstku hybridů byly dosaženy u ROSS 308 ve výkrmovém testu do období 35 dnů věku. Na druhou stranu kohoutci obou hybridních kombinací COBB 500 a ROSS 308 měli vyšší živou hmotnost a nižší spotřebu krmné směsi na kg 1 přírůstku. V každé hybridní kombinaci uhynulo během období výkrmu 2,3 % kuřat. U hybridů ROSS 308 byla zjištěna vyšší jatečná výtěžnost a vyšší hmotnost prsní a stehenní svaloviny. Bylo tomu tak proto, že hybridi ROSS 308 dosáhli vyšší živou hmotnost o 14 g během prodlouženého období testu výkrmnosti ve věku 42 dnů. U kohoutků však byla zjištěna vyšší živá hmotnost a nižší spotřeba krmné směsi ve srovnání se slepičkami obou genotypů. Během období výkrmového testu uhynulo 4,6 % kuřat COBB 500 a 5,4 % kuřat ROSS 308 v důsledku nesprávné ventilace, což je velmi důležitý faktor pro dobré životní podmínky zvířat obecně. Diference mezi hybridy COBB 500 a ROSS 308 byla 0,2 % v jatečně výtěžnosti, 7 g v hmotnosti prsní svaloviny a 9 g v hmotnosti stehenní svaloviny. The absolute and most fundamental aim of this bachelor's thesis is to compare and understand the production and processing measures of broiler parent combination and their offspring for the desirable breeding type for commercial breeders of broiler chickens COBB 500 and ROSS 308 in that order. The data was obtained from Mezinárodní testování drůbeže, státní podnik (International poultry testing, state enterprise) in Ústrašice. Parent testing of COBB 500 and ROSS 308 consisted of parent rearing periods of up to 154 days of age respectively. The fattening test was made in two sets of 35 days and 42 days in that order. Testing evidence results suggested that ROSS 308 chickens obtained a quite substantial live body mass/weight compared to COBB 500 on due ending course of the set rearing period in parent testing. However, lower feed consumption per head/day was realized in COBB 500 hybrids with reference to this period respectively. In addition to that, lower feed consumption was observed per day/head in COBB 500 hybrids during the laying period. Despite the deduced observations though, a higher egg number/hen housed was laid by ROSS 308 hens but the live hatched chickens per laying hen were higher in COBB 500 hens. Higher live body mass/weight and lower feed consumption per kg gain hybrids were realized in ROSS 308 at the fattening test period of 35 days of age. On the other hand, roosters of both hybrid combinations COBB 500 and ROSS 308 gained a higher live body mass/weight and lower feed consumption per kg gain. 2.3 % of chickens died during the fattening period in each hybrid combination. Higher carcass yield, breast, and thighs muscle mass were in this work determined in ROSS 308 hybrids. This is because ROSS 308 hybrids successfully attained a higher live body/weight of at least about 14 g during a prolonged fattening testing period of 42 days of age. Higher live body mass/weight however and lower feed consumption was determined in cocks obviously in comparison with hens in both genotypes. In that order,4.6 % of COBB 500 chickens and 5.4 % of ROSS 308 chickens died during the fattening period due to improper ventilation yet a very imperative factor to animal welfare at large. genotypic difference between COBB 500 and ROSS 308 was at 0.2 % in slaughter yield, 7 g in breast mass, and 9 g in thighs weight respectively.

PROMBERGER, Markus
2022 - English
In this thesis a sequence to sequence autoencoder for amino acid sequences is constructed. The latent representation of the autoencoder is then used to classify the amino acid sequences according to their animal kingdom. The data consists of sequences from three different kingdoms, mammals, fish and birds. The thesis includes the preprocessing necessary for the data, the construction of the sequence to sequence autoencoder and the process of classification in the latent space.

Detection of Lyme disease spirochetes and Borrelia miyamotoi in samples of Czech patients
KAPURANI, Helena
2021 - English
Lyme borreliosis is a disease caused by infection of selected members of the Borrelia burgdorferi sensu lato complex, a genus that keeps growing. With time, more and more members of this complex were identified as pathogenic for humans. This work aims to detect the spectrum of Borrelia spirochetes present in samples of Czech patients diagnosed with Lyme disease. Analysis will be used to suggest a tendency between the presence of the spirochetes' DNA found and the diagnosis of the patients.

HEMR, Adam
2021 - English
Tato bakalářská práce se zabývá vztahy Velké Británie a Německa ve třicátých letech dvacátého století. Snaží se postihnout politický vývoj od konce První světové války až po vypuknutí Druhé světové války, přičemž věnuje hlavní pozornost politice appeasementu; důvodům jejího vzniku a jejímu hlavnímu představiteli Nevillu Chamberlainovi. Zároveň si klade za cíl osvětlit i důvody neúspěchu jak Nevilla Chamberlaina, tak jeho politiky. Ve svém závěru se práce pokouší o obhajobu appeasementu i jeho hlavního reprezentanta. The goal of this thesis is to analyze the relationship of Great Britain and Germany in the 1930s. It concerns itself with the political development in Britain between the world wars while focusing on the policy of appeasement, its roots, and its most famous exponent, Neville Chamberlain. The thesis also hopes to explain why both the Prime Minister and his policy failed. In its conclusion the thesis argues in defense of appeasement as well as in defense of Neville Chamberlain.

Mass spectrometry in structural proteomics: study of viral protein complexes
RAVI, Anirudhan
2021 - English
This thesis investigated the avian reovirus sigma NS protein and its interaction with RNA using mass spectrometric methods. The sigma NS structure is still not known; thus, hydrogen-deuterium exchange and cross-linking coupled to mass spectrometry were employed to understand protein conformation. This research provides insights into protein-RNA interactions and the obtained data will be used in future work to predict protein structure.

Extracelulární váčky během ontogeneze tasemnice \kur{Schistocephalus solidus.}
BUŠKOVÁ, Nikol
2021 - English
This bachelor thesis focuses on extracellular vesicles (EVs), which are small transport units derived from membranes and released by a variety of cells. Based on their biogenesis, two main classes were observed. First class, referred to as exosomes, are vesicles formed during an endosomal pathway and released by multivesicular bodies. The second class, microvesicles, are formed by a direct budding of the plasma membrane. We focused on EVs of different life stages of the tapeworm Schistocephalus solidus (Cestoda: Diphyllobothriidae), a parasite of fish-eating birds with a three-host life cycle. For our experiments, a full life cycle of S. solidus was established under laboratory conditions. EVs secretion was studied in procercoids fom copepods, plerocercoids from fish and adults from the cultivation medium. We have observed biogenesis of EVs on the surface of procercoid and plerocercoids of S. solidus using transmission electron microscopy and successfully purified EVs from the cultivation medium. Furthermore, we observed differences in secretory activity during the maturation of plerocercoids and a difference in releasing EVs from different parts of the the tapeworm surface.
