The thesis deals with a design of a comparing interferometer. It concerns a setup of two interferometers, one of them is a Michelson and another a Fabry-Pérot type. This set-up is made to compare results of length measurements simultaneously performed by each of them. In the Theory, basic principles of Michelson and Fabry-Pérot interferometers are described. A special attention is paid to an innovative method of length measurement with tunable lasers and optical frequency comb. In the Practical Part, so-called Pilot Experimental Setup is described. It is a prototype that has been used to perform basic experiments on comparing of the two above mentioned methods. Based on experimental results and practical experience with the Pilot Experimental Setup, a Final Setup is designed. It comes in a form of a stand-alone instrument.

In comparison to men, the number of X-linked genes is doubled in women as they have two chromosomes X while men are hemizygotes for X-linked genes. This imbalance is compensated by X inactivation (XCI) process, also known as primary X-inactivation, occurring in the early stage of embryogenesis. X inactivation is a random process and females are mosaics of two cell populations. The ratio of expressed alleles in women can be random (50:50) or skewed (≥80:20). The skewed X inactivation may occur due to selection when one of the alleles is preferentially inactivated (secondary X inactivation). In this study XCI status in heterozygous females with various severity of phenotypic symptoms and traits in selected X linked inherited metabolic diseases is analysed, with the focus being Fabry disease - the deficiency of the enzyme alpha-galactosidase A encoded by GLA gene. Moreover, XCI in one family with X linked agammaglobulinemia is examined. Mutant alleles and XCI status based on various loci, different methodical approaches and different tissues is subjected to examination. For the first time, the direct analysis of GLA gene transcript to detect the allele ratio was used alongside with the single-nucleotide polymorphisms in the IDS and LAMP genes for allele-specific expression (ASE) and the AR, RP2 and...

Human autopsy or biopsy tissue samples, mouse models and cell cultures of various types represent the most common materials in the investigation of cell pathogenesis of inherited diseases. This dissertation is devoted to all these approaches in the study of two X-linked lysosomal storage diseases, Fabry disease (FD,α-galactosidase A (AGAL) deficiency) and mucopolysaccharidosis type II (MPSII, idunorate-2- sulfatase (IDS) deficiency). The primary goal of the work was analysis of lipid blood group B antigens with terminal α-galactose (B-GSL) in the pancreas of FD patients with blood group B (FD-B).,In addition to the main glycosphingolipid (GSL) substrate, globotriaosylceramide (Gb3Cer), B-GSLs represent another minor substrate of AGAL. The deposition of undegraded B-GSL has been demonstrated in FD-B pancreas where it was significantly higher than in other organs such as the kidneys and lungs which accumulate mainly Gb3Cer. High concentration of lipid and non-lipid B-antigens was primarily confirmed in exocrine acinar epithelial cells of FD-B, accompanied by massive accumulation of ceroid (secondary sign of lysosomal storage). Unlike acini, the endocrine portion of the pancreas remained unaffected by accumulation of AGAL substrates. This interesting phenomenon of cell biology shows how a specific...
