Variabilita molekulární diversity a proteinové struktury Toll-like receptorů v populacích galapážských drozdců

Fragmentation of populations and habitat loss is a hallmark of ongoing 6th mass extinction, and in terms of conservation genetics, it is necessary to understand the changes that it entails. It is essential to understand the impact of population size on the variability of the immune genes for the future in conservation genetics. In order to better understand genetic variability, it is not enough to analyze DNA sequences only, but focus on functional protein variability. This paper examines the physiochemical properties and structures of the individual haplotypes of Toll-like receptors in allopatric populations of Galapagos mockingbirds (Mimus sp.). Toll-like receptors play a key role in the immune system, where they form the link between innate and adaptive immune responses, by the detection of pathogens. The data in this work reveal the variability of their diversity across the small Galapagos populations and the large continental populations of the northern mockingbird (M. polyglottos). Comparison of heterozygosity of populations revealed that the proportion of heterozygotes is smaller in galapagos populations than in the continental population. This suggests a greater impact of diversifying selection in the continental population, or a reduction in genetic variability in Galapagos populations due to founder effect and smaller population size. In addition to the description of genetic diversity, the physiochemical properties of the discovered haplotypes were described, the structures of all TLR1B, TLR4 and TLR15 haplotypes were modeled and compared

Comparison of Global Fintech Companies and Banks

Bakalářská práce zkoumá aktuální vzestup finančních technologií a patřičné společnosti analyzuje a porovnává s bankovními institucemi. Stěžejní část a přínos práce je zhodnocení růstového potenciálu finančních technologií a nastínění možného vývoje finančního trhu v budoucích letech. První část práce definuje termín „Fintech“ a následně staví teoretické základy pro analýzu společností. Analýza je tvořena několika částmi, jejichž struktura je koncipována tak, aby bylo možné provést srovnání institucí na první pohled velmi vzdálených. Finální část této práce, komparace Fintech společností a bank, odhaluje slabiny bankovního sektoru a naproti tomu obrovskou převahu finančních technologií v určitých relevantních aspektech. Vzniká hrozba pro bankovní systém v jeho klasickém pojetí, přičemž budoucnost nabízí dva scénáře. Jednotlivé bankovní domy se buď adaptují na nové podmínky na trhu nebo v krajním případě hrozí jejich zánik.This bachelor thesis discusses the current trend of thriving Fintech companies and analyses the respective institutions. The purpose of the thesis and the outcome would be to valorise the growth potential of Fintech and to outline the possible evolution of financial markets over the next years. The first part defines the term “Fintech” and furthermore lays out a theoretical background indispensable for the analysis of the companies. The analysis comprises of several parts which are compiled to allow further comparison of, at first glance, entirely different institutions. The final part of the thesis, the comparison of Fintech companies and Banks, reveals weaknesses of the banking industry and a vast superiority of Fintech companies over banks in particular relevant aspects. A considerable threat to the banking system emerges on the market, which leaves us with two scenarios. Banks either have to adapt to the newly set market conditions or at worst banks could even disappear from the financial market

Novel Agonists of the Juvenile Hormone Signaling

Juvenile hormone (JH) plays a key role in insect development. In larval stage, JH prevents the insect to metamorphose. While JH is unique to arthropods and absent from vertebrates, it represents potential tool for insect control. Combination of cell-based assay and high-throughput screening enabled to find candidate JH agonists (JHags) that activate JH signaling via juvenile hormone receptor (JHR). This thesis aims to elucidate the effect of these JHags on three evolutionary distinct insect species in vivo and possible selectivity of the JHags for individual insect species in vitro. In addition, we provide evidence that JHR from hemimetabolous species Blattella germanica and Prorhinotermes simplex binds JH in vitro. This thesis provides useful findings and tools for development of new JHags that could be selective for particular insect taxa
