The Czech Treasury Yield Curve from 1999 to the Present
No full textThe author estimates the Czech Treasury yield curve at a daily frequency from 1999 to the present. He uses the parsimonious yield curve model of Nelson and Siegel (1987), for which he suggests a parameter restriction that avoids abrupt changes in parameter estimates and thus allows for the economic interpretation of the model to hold. The estimation of the model parameters is based on market prices of Czech government bonds. The Nelson-Siegel model is shown to fit the Czech bond price data well without being over-parameterized. Thus, the model provides an accurate and consistent picture of the Czech Treasury yield curve evolution. The estimated parameters can be used to calculate spot rates and hence par rates, forward rates or the discount function for practically any maturity. To eh author´s knowledge, consistent time series of spot rates are not available for the Czech economy.yield curve, spot rates, treasury market, Nelson-Siegel
Day length affects immune cell numbers in deer mice: The influence of age, sex, and in utero photoperiodic history
No full textThe extent to which day length affects immune function was examined in the present study. Three goals were pursued: 1) to confirm and extend the observation that the immune systems of adult deer mice (Peromyscus maniculatus) are responsive to changes in photoperiod, 2) to examine the development of the photoperiod-associated changes in immune function, and 3) to discover whether photoperiodic information transmitted to the young during gestation influences immune function. In experiment 1, adult mice housed in short days had higher white blood cell and lymphocyte numbers than their long-day cohorts. Red blood cell and differential cell counts did not differ between long- and short-day animals. No sex differences were observed in the pattern of immune responses to photoperiod. The effect of photoperiod on immune cells in prepubertal animals was examined in experiment 2; a similar pattern of results was obtained as that for experiment 1, suggesting that the photoperiodic effect on the immune system is not mediated by sex steroid hormones. Prenatal and postnatal photoperiodic effects on immune cells were examined in experiment 3; pups gestated in one day length were cross-fostered to mothers in the same day length conditions or to mothers maintained in the alternative day length. The results of experiment 3 suggested that photoperiodic information transmitted from the mother to the young in utero subsequently affected immune systems of the pups. Animals gestated in short day lengths displayed higher immune status throughout life than mice gestated in long days. These results are discussed from an adaptive functional perspective

JM-20, a Benzodiazepine-Dihydropyridine Hybrid Molecule, Inhibits the Formation of Alpha-Synuclein-Aggregated Species
No full text\ua9 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.Studies showed that JM-20, a benzodiazepine-dihydropyridine hybrid molecule, protects against rotenone and 6-hydroxydopamine neurotoxicity. However, its protective effects against cytotoxicity induced by endogenous neurotoxins involved in Parkinson’s disease (PD) pathogenesis have never been investigated. In this study, we evaluated the ability of JM-20 to inhibit alpha-synuclein (aSyn) aggregation. We also evaluated the interactions of JM-20 with aSyn by molecular docking and molecular dynamics and assessed the protective effect of JM-20 against aminochrome cytotoxicity. We demonstrated that JM-20 induced the formation of heterogeneous amyloid fibrils, which were innocuous to primary cultures of mesencephalic cells. Moreover, JM-20 reduced the average size of aSyn positive inclusions in H4 cells transfected with SynT wild-type and synphilin-1-V5, but not in HEK cells transfected with synphilin-1-GFP. In silico studies showed the interaction between JM-20 and the aSyn-binding site. Additionally, we showed that JM-20 protects SH-SY5Y cells against aminochrome cytotoxicity. These results reinforce the potential of JM-20 as a neuroprotective compound for PD and suggest aSyn as a molecular target for JM-20

Abstract
Infertility due to the inability of the uterus to carry a pregnancy ranks among the most unresolved issues in reproductive medicine. It affects millions of women worldwide who have congenital or acquired uterine affections, often requiring hysterectomy, and potentially represents a considerable fraction of the general infertile population. Patients suffering from severe uterine infertility are currently compelled to go through gestational surrogacy or adoption; both approaches, unfortunately, deprive them of the maternal experience of pregnancy and birth. Uterine transplantation represents an outstanding, yet complex, perspective to alleviating definitive uterine infertility. In the past decades, a number of scientific experiments conducted both in animals and women, focusing on uterine transplantation, have led to promising results. Collectively, these findings undoubtedly constitute a sound basis to clinically apply uterine transplantation in the near future. This paper is, however, an overview not only of the extent and limitations of accumulated scientific knowledge on uterine transplantation, but also its ethical implications, in an effort to define the actual place of such an approach among the therapeutic arsenal for alleviating infertility.

Translation and interpretation: Translation redundancy reconsidered
No full textInterpretation is an integral part of the process of translating. This article raises the question of whether interpretation fo a literary work by a translator should be guided by extratextual factors or not. The discussion is illustrated with examples taken from David Hawkes' translation of a Chinese classic, A Dream of Red Mansions. As the work of a scholar-translator, Hawkes' version is richly supplemented with disclosures concerning the characters and explanations of the cultural environment embodied in the novel. In many cases, however, this translation procedure is redundant and explanatory, enlightening the readers but at the same time robbing them of the pleasure of literary interpretation and cultural exploration. By means of this illustration of translation redundancy, the author points out that there is difference between a scholar who helps the interpretation fo a work and a translator who presents a work close to its original version. It is particularly important to pay attention tot his difference in literary translations in a cross-cultural situation involving two enormously different cultures.Language & LinguisticsA&HCI0ARTICLE1,SI115-12

Photoperiodic effects on steroid negative feedback in female prairie voles (Microtus ochrogaster).
No full textBreeding in prairie voles is mainly restricted to the autumn and winter of most years. The organization of estrus in female prairie voles is unusual because behavioral estrus is induced by chemosensory stimuli from the urine of adult conspecific males. Isolated females exhibit undetectable levels of estradiol and never display estrous behavior, yet exposure to male urine causes a cascade of endocrine changes that evoke estrogen secretion from the ovaries and estrous behavior within 24 hr. In the prairie vole, the extreme dependence of estrus on chemosensory stimuli raises the possibility that their ovaries may be less prominent in the regulation of gonadotropin secretion than in species with more endogenously organized estrous cycles. The present study examined the contribution of the ovaries in luteinizing hormone (LH) regulation in prairie voles. Females were maintained for 9 weeks in either long (LD 16:8) or short (LD 8:16) photoperiodic conditions, a blood sample was obtained, and then animals were either ovariectomized or received a sham procedure. Another blood sample was obtained a week later and assayed for serum LH. Blood serum LH levels were significantly reduced in short-day voles, compared to long-day animals. After ovariectomy both long-day and short-day voles exhibited equivalent elevations in LH levels. This study provides evidence that photoperiod is measured in female voles and the ovaries appear to produce sufficient steroids to suppress LH release
