Multiple sclerosis (MS) is one of the most common neurological diseases. This neurodegenerative autoimmune disease manifests as inflammatory and demyelinating impairment of the central nervous system (CNS). Although some studies demonstrated associations between altered steroidogenesis and pathophysiology of MS as well as the importance of steroids in the pathophysiology of MS, the knowledge concerning the steroid metabolome in female patients is limited. Hence, 51 steroids and steroid polar conjugates were measured in the serum of 12 women with MS, untreated with steroids and 6 agecorresponding female controls with the use of gas chromatography - mass spectrometry (GC-MS). The data were processed using age adjusted ANCOVA, receiver operating characteristics (ROC) analysis and orthogonal projections to latent structures (OPLS). Our data show higher levels of circulating C21 steroids including steroid modulators of ionotropic type A γ-aminobutyric acid (GABA A) receptors and glutamate receptors. Furthermore, the levels of GABAergic androsterone and 5-androsten-3β,7α,17β-triol were also higher in the female MS patients. In conclusion, the data demonstrate higher levels of circulating C21 steroids and their polar conjugates and some bioactive C19 steroids in women with MS, which may influence neuronal activity and affect the balance between neuroprotection and excitotoxicity., R.

Předmětem studie je teoretická analýza feministické antropologie jako relativně autonomního výzkumného směru a svébytné antropologické disciplíny. Zvláštní pozornost bude věnována vývojovým proměnám feministické antropologie. Cílem studie je přispět k ap- likaci genderového přístupu na výzkum sociokulturních jevů. Proto je feministická antropologie analyzovaná jako přístup, který v opozici k tradičnímu androcentrickému studiu člověka vnáší do vědy o kultuře „ženský hlas“ a genderovou perspektivu., The subject of this study is a theoretic analysis of feministic anthropology as a relatively autonomous research approach and an independent anthropological discipline. Special attention will be paid to evolutionary changes of feministic anthropology. The study aims at enhancing the use of gender approach when researching socio-cultural phenomena. That is why feministic anthropology is analysed as an approach which – as opposed to the traditional androcentric study of man – brings into cultural science a “woman’s voice” and gender point of view., Václav Soukup, and Literatura
Sofia Kovalevskaya was not only a great Russian mathematician, but also a writer and advocate of women's rights in the 19th century. After concluding her sexondary schooling, Sofia was determined to continue her education at the university level. She travelled to Heidelberg to study mathematics, but discovered there that as a woman she could not graduate. In 1870 she moved to Berlin to study with Karl Meierstrass, in 1874 she was granted a Ph.D. from the Göttingen University. In 1883 she received an invitation from Gösta Mittag-Leffler to lecture at the University of Stockholm. Sophia's most famous work is on the theory of partial differential equations, and on the rotation of a solid body about a fixed point. Sophia died very young, at the age of 41, from pneumonia., Ivo Kraus., and Obsahuje bibliografii
