Extraction of Available Information from SSH Protocol Headers
Ďurčanský, Norbert ; Bartoš, Václav (referee) ; Kořenek, Jan (advisor)
This paper analyzes issue regarding to extraction of available information from SSH protocol. To achieve this aim, knowledge about SSH protocol were used to implement plugin for FlowMon exporter. During the testing plugin was tested on real network and validated in terms of stability, efficiency and accuracy. The result plugin allows us to extract information from SSH protocol and futher analysis  without decryption of traffic.
The signs of odontogenesis externally to the prospective functional dentition in the experimental model
Fábik, Jaroslav ; Hovořáková, Mária (advisor) ; Buchtová, Marcela (referee)
6 Abstract The development of the mouse tooth primordium is an important model for studying odontogenesis, as well as general organogenesis. The development of the mouse lower incisor is of remarkable interest. The epithelial anlage of the mouse lower incisor is interconnected with the vestibular anlage via the epithelial bridges. According to some authors, the epithelial bridges represent an area, where the transient rudimentary incisor germ appears. From a morphological point of view, the first sign of ongoing epithelial-mesenchymal interactions during early odontogenesis is the thickening of oral epithelium. From a molecular point of view, it is the expression of the Shh, Eda, Edar, Pitx2, Bmp2, Bmp4 and Dlx2 genes. Except for the transcription domain, representing the proper signalling centre of a developing prospective incisor, a transient transcription domain, localized anteriorly and superficially, appears in the odontogenic zone of the epithelium during early development. The anterior transcription domain originates in the area of epithelial bridges, and according to some authors, from an evolutionary point of view, it corresponds with the signalling centre of the rudimentary incisor germ. The aim of this diploma thesis was to compare the temporospatial dynamics of SHH and EDA protein expression in...
Early tooth development of Tabby mice
Smrčková, Lucie ; Peterková, Renata (advisor) ; Černý, Robert (referee)
The developing mouse dentition is a very useful tool to study molecular regulation of odontogenesis and also organogenesis. The embryonic mouse dentition comprises developing functional tooth primordia as well as rudimentary tooth primordia. These rudiments arrest their growth during development and either degenerate or become a part of a functional tooth. Mice with gene defects also allow elucidation of a function of genes, their products and signalling pathways. The protein ectodysplasin is essential for development of ectodermal derivatives - skin, hair, glands and teeth. The Tabby mice have a mutation in the Eda gene, which encodes the protein ectodysplasin, and they display a number of dentition anomalies. Early development of the lower jaw dentition in Tabby embryos has been already morphologically described. As a prerequisite for understanding regulatory mechanisms of odontogenesis in Tabby mice, it is also necessary to map the spatiotemporal dynamics of signalling centres that express Shh in both the rudimentary and functional tooth primordia. The aim of this thesis was to compare the signalling centres based on the Shh expression and its spatiotemporal dynamics in the lower jaw of Tabby and WT mouse embryos. Then the Shh data were correlated with known morphological data to clarify the...
Shared mechanisms of development of vertebrate body appendages
Vintr, Jan ; Soukup, Vladimír (advisor) ; Krylov, Vladimír (referee)
Vertebrate body appendages include a number of structures such as limbs, paired and median fins, the tail bud, the cloacal region, barbels or pharyngeal arch derivatives. Despite differences in form and function, these appendages share a number of developmental genetic mechanisms. Development of these structures is chiefly regulated by Fgf, Shh, Wnt, Tgf-β and retinoic acid signalling pathways, activity of transcription factors such as Hox or Tbx along with cis-regulatory elements controlling the genes in which these factors are encoded. A recurring feature shared by some of the herein discussed anatomical structures is a transient epithelial ridge whose activity influences production and proliferation of the adjacent mesenchyme. Some are also instructed by a signalling centre, which confers asymmetry to the structure. In this text, the various appendages are compared on the basis of their development in relation to tetrapod limbs and theories evaluating the emergence of vertebrate paired appendages. The fin fold theory and archipterygial theory are discussed in the light of recent data provided by evolutionary developmental biology. All together, this thesis evaluates shared and derived characteristics of vertebrate body appendages with the aim to provide a basis for the upcoming work on the role...
