Metabolic syndrome and steroid spectrum
Pospíšilová, Hana ; Stárka, Luboslav (advisor) ; Hána, Václav (referee) ; Fingerová, Helena (referee)
Sex steroids influence the storing of fat, and differences in the distribution of fat are a typical secondary sexual characteristic. Androgens act on fatty tissues in males either directly through stimulation of the androgen receptor or indirectly through aromatization of the estrogen receptor. Androgens can be classified as aromatizable or non-aromatizable. Testosterone (T) is the main aromatizable androgen, while its metabolite dihydrotestosterone (DHT) is a non-aromatizable androgen that acts only through the androgen receptor. It is precisely this difference in having activity only through the androgen receptor that has given rise to the hypothesis concerning the differing effects of DHT and T on body composition, with DHT possibly being responsible for male-type fat distribution. As part of my post-graduate studies we analyzed the dependence serum levels of T and DHT on age, as well as changes in their ratio with age. Further, we sought relationships between aromatizable and non-aromatizable androgens and metabolic and anthropometric parameters. We also focused on following any changes in steroidogenesis in obese males. We showed that before puberty the dominant androgen is rather DHT than T, that the fDHT/fT ratio during the life of adult males is constant, and that there is no evidence of a reversal...

Structured abstract Study objectives: Ovarian carcinoma 1/ comparison of sensitivities among monitored markers CA 125, HE4, CA 19-9, CEA, TK, TPS, MonoTotal 2/ comparison of false positivity of markers CA 125 and HE4 3/ use of CA 125, HE4 and ROMA index in the diagnostics of ovarian carcinoma 4/ use of CA 125 and HE4 in the follow-up of ovarian cancer Endometrial carcinoma 1/ feasibility of use of biomarkers CA125 and HE4 in patients with endometrial cancer in pre- operative management Study design: Retrospective data analysis Settings: Department of Obstetrics and Gynecology, Medical Faculty and Teaching Hospital in Pilsen Patients and Methods: Ovarian cancer 1/ Sensitivity of markers CA 125, HE4, CA 19-9, CEA, TK, TPS, and MonoTotal was assessed in 266 patients - 19 with ovarian cancer and 247 with benign disorders. 2/ False positivity of markers CA125 and HE4 was evaluated in a total of 390 patients with benign diagnoses - 60 women with endometriosis, 70 pregnant patients, 67 patients with ascites, 60 with pleural effusion, 25 with cardiac failure , 80 with renal insufficiency and 28 with hepatic failure. 3/ As a part of this objective we evaluated 552 patients with abnormal pelvic abnormality - 30 women had a histologically confirmed malignant ovarian tumor. Other 522 women had a benign condition. The...
Observation of human sperm cell immunogenic properties
Cibulka, Jan ; Ulčová-Gallová, Zdeňka (advisor) ; Fingerová, Helena (referee) ; Madar, Jindřich (referee) ; Šíma, Petr (referee)
The issue of human infertility is becoming increasingly pressing, especially in so- called industrially developed countries. Formally, we can share the infertility attributes between the male and the female partner (as a male and female infertility factor), but the problem finally affects the whole parental couple. Perhaps, due to the complexity of the female reproductive tract, it is estimated that over 40% of the reproductive failure is hidden in one or more of its parts. The "strong point" of the male factor is derived from the pathological sperm count. For the remaining 15 to 20% of causes, whether morphological or functional, cannot be to find either clearly or not at all. We talk about the otherwise unexplained infertility, that can be caused in up to 30% immunologically. Due to broad concept of immunology of reproduction, we have chosen literally as a probe into this issue in all respects unique spermatic cell that represents not only a carrier of genetic information, but also a set of antigenic structures. This cell seems to be perfect for this task, because of its availability to most basic laboratory techniques. We will try to familiarize ourselves with some of the obstacles that may prematurely end its mission, especially with the antibodies against its antigenic structures (ASA -...
