Evaluation of Business Performance Through Financial Analysis Tools
Mrhačová, Lenka ; Teplá, Olga (referee) ; Hornungová, Jana (advisor)
This bachelor thesis deals with the evaluation of the performance of the company UNIS COMPUTERS, a. s. using methods of financial and strategic analysis for the years 2017 to 2021. The theoretical part will describe individual methods of financial analysis as well as indicators that will subsequently be applied in the work. In the practical part, selected indicators are applied to a selected company. The last part deals with suggestions for improving the current situation of the company.

Ethical issues of assisted reproduction with emphasis cryopreservation methods
Zajíčková, Markéta ; Haškovcová, Helena (advisor) ; Křepelka, Petr (referee) ; Teplá, Olga (referee)
Human infertility is not a new phenomenon, but it is as old as humanity itself. Currently in most developed countries, the number of couples who have a problem with childbearing is growing. This is due, among other things, to the lifestyle associated with career development and postponement of parenthood. While in the past infertile couples usually had only two options to deal with their sterility - childlessness and a substitute life program, or adopting a child. Today, infertile couples have a third option and this is the treatment of infertility using assisted reproduction methods. This year, exactly forty years have elapsed since the birth of the first child by means of extracorporeal fertilization. Already then the assisted reproduction was considered a method that is ethically problematic. Numerous specialists, such as physicians, biologists, lawyers, philosophers, theologians, and others, have been involved in the quest for ethical issues. Not only there has been no solution to some problems during the whole lifetime of assisted reproduction on which most experts and the general public would agree, but with the gradual development of this treatment method new problems have arisen. Today's stage of development of artificial insemination techniques and procedures together with modern...

Fluorescent analysis of the differential protein expression in normozoospermic and asthenozoospermic sperm samples

Asthenozoospermia is one of the main seminal pathologies underlying male infertility. Previous proteomic studies have demonstrated the significant differences in the protein profiles between normozoospermic and asthenozoospermic sperm samples. Since these studies were primarily focused on the identification of differentially expressed proteins by mass spectrometry, we aimed to evaluate the ability of our diagnostic antibodies to detect the differential expression of selected protein markers by fluorescent microscopy and flow cytometry techniques. Therefore, we analyzed sperm samples from 30 men with normal and 30 men with astheno spermiograms, average by the panel of our diagnostic anti-human sperm (Hs) antibodies. Fluorescent microscopy and flow cytometry analysis revealed quantitative differences in the protein abundances between normo and astheno sperm samples, namely, in GAPDHs, evaluated with Hs-8 MoAb, VCP, evaluated with Hs-14 MoAb, and ATP synthase, evaluated with MoAb Hs-36. From the methodological point of view, we observed very high correlation between the data obtained by fluorescent microscopy and flow cytometry techniques and therefore both methods are useful for evaluation of protein differences associated with asthenozoospermia. From the clinical point of view, we observed the strong association of the low sperm motility in the sample with the expression of proteins, playing an important role in sperm energy metabolism (expected), but also with the expression of all tested intra-acrosomal proteins. These findings further demonstrate asthenozoospermia as a complex semen disorder frequently associated with other semen pathologies, which are not diagnosed by basic semen analysis, and the possibility to use monoclonal antibodies as a tool for diagnosis of protein associated sperm pathologies in the semen with the low sperm motility.

Flow cytometry (FCM) sperm assessment In normozoospermic and asthenozoospermic men using monoclonal antibodies against sperm proteins
Čapková, Jana ; Kubátová, Alena ; Děd, Lukáš ; Teplá, O. ; Pěknicová, Jana
Recent studies have shown that infertility affects an estimated 15% of all couples. Male infertility is the primary or contributing cause in 60% of these cases. Consequently, application of methods of assisted reproduction is increasing. These methods would benefit from extended evaluation of the sperm quality. For this purpose, we analyzed sperm proteins in men with normal spermiograms and with asthenozoospermia. Ejaculates of both groups were tested with a set of well-characterized monoclonal antibodies (MoAbs) to human sperm. No statistically significant differences were found between normospermics and asthenospermics in the expression of sperm surface proteins clusterin, evaluated by Hs-3 MoAb, and semenogelin, evaluated by Hs-9 MoAb. On the other hand, flow cytometry revealed quantitative differences between normozoospermic and asthenozoospermic men in GAPDHS (glyceraldehyde phosphate dehydrogenase human sperm-specific glycolytic enzyme), evaluated by Hs-8 MoAb, VCP (valosin-containing protein), detected with Hs-14 MoAb, and PRKAR2A (cAMP-dependent protein kinase type II – alpha regulatory subunit) detected by MoAb Hs-36. Asthenozoospermic men displayed significantly reduced expression of intra-acrosomal proteins with a likely decrease in sperm quality, and thus a negative impact on successful reproduction.

Iscare IVF a.s. had a long record of successful azoospermic treatment since 1997, when the first pregnancies by MESA a TESE were published in the Czech republic. A series of diferent implanted laboratory techniques supported good results from last year. The medical problem is solved during the other field of application-histlogical findings and immunofluorescent methods.
