- Description:
- The subclass of triglyceride -rich lipoproteins - remnant -like particles (RLP) seems to be strong and independent risk factor for cardiovascular disease. We eva luated the role of RLP and other risk factors (RF) with sonographically measured intima - media thickness of carotid arteries (IMT CCA) in a cohort of Czech population including women defined according to the time after menopause. We investigated relation of IMT CCA to age, weight, central obesity, plasma lipids including remnant -like particles cholesterol (RLP -C) and triglycerides (RLP -TG) in 136 men and 160 women. Using multiple linear regression analysis, significant association between IMT CCA and RLP -C was found in women 1 -7 years after menopause. In the whole group of women, only age and fasting blood glucose were independently associated with IMT CCA. In men only age significantly correlated wit h IMT CCA. Significant decrease of all plasma lipids betwe en 1988 and 1996 in men was detected, while in women significant increase in triglycerides and no change in non -HDL cholesterol was observed. RLP -C was the strongest independent RF for atherosclerosis in postmenopausal women but its as sociation with IMT CC A was limited to several years after menopause. In conclusion, women changing reproductive status could be more sensitive to atherogenic impact of remnant lipoproteins., J. Piťha, J. Kovář, Z. Škodová, R. Cífková, P. Stávek, L. Červenka, T.

- Subject:
- fotosyntéza, photosynthesis, aridity, carotenoids, chlorophyll, fluorescence, photoinhibition, Pistacia lentiscus L., seasonality, sex, 2, and 581
- Language:

- Description:
- In this work, photosystem II (PSII) photochemistry, leaf water potential, and pigment contents of male and female Pistacia lentiscus L. were investigated during a seasonal cycle at three different, arid locations: superior semiarid, inferior semiarid, and arid. The results showed that the gender, season, and the site conditions interacted to influence the quantum yield and pigment contents in P. lentiscus. Predawn leaf water status was determined only by the site and season. The annual patterns of PSII maximum quantum efficiency (Fv/Fm) were characterized by a suboptimal activity during the winter, especially, populations with the more negative water potential exhibited a lower chlorophyll (Chl) a content and chronic photoinhibition irrespective of a gender. We also demonstrated that both photochemical or nonphotochemical mechanisms were involved to avoid the photoinhibition and both of them depended on the season. This plasticity of photosynthetic machinery was accompanied by changes in carotenoids and Chl balance. In the spring, the female Fv/Fm ratio was significantly higher than in male individuals, when the sexual dimorphism occurred during the fruiting stage, regardless of site conditions. P. lentiscus sex-ratio in Mediterranean areas, where precipitations exceeded 500 mm, was potentially female-biased. Among the fluorescence parameters investigated, nonphotochemical quenching coefficient appeared as the most useful one and a correlation was found between Chl a content and Fv/Fm. These results suggest that functional ecology studies would be possible on a large scale through light reflectance analysis. and S. Ait Said ... [et al.].

4. General anesthesia and electrocardiographic parameters in in vivo experiments involving rats
- Creator:

- Type:
- model:article and TEXT
- Subject:
- ECG parameters, general anesthesia, sex, chronobiology, and rat
- Language:
- English
- Description:
- In in vivo cardiovascular or toxicological studies involving rat models, changes in selected electrocardiographic (ECG) parameters are monitored after various interventions to assess the origin and development of heart rhythm disorders. Each ECG parameter has diagnostic significance; as such, commonly evaluated ECG parameters, including heart rate, PR interval, P wave duration, P wave amplitude, QRS complex, QT and QTc interval duration, R wave and T wave amplitude, of rats under various types of general anesthesia were the focus of this study. Studies that performed in vivo cardiovascular or toxicological experiments in rats were retrieved from a search of the Web of Science database for articles published mainly between 2000 and 2021. In total, the search retrieved 123 articles. ECG parameters that were reported as baseline or control values were summarized and averages with ranges were calculated. It is important to be cautious when interpreting results and, in discussions addressing the mechanisms underlying a given type of arrhythmia, acknowledge that initial ECG parameters may already be affected to some extent by the general anesthesia as well as by sex and the time of day the experiments were performed. and autoři: Pavol Svorc, Pavol Svorc Jr

6. Perverzní sex a normální gender: normalizační sexuologie promlouvá o sexu a genderu
- Creator:

- Subject:
- sexuologie, normalizace (1969-1989 : Československo), sex, gender, sexology, "normalization", Czechoslovakia, 1969-1989, deviance, sex customs, 18, and 316
- Language:
- Czech
- Description:
- The period of Normalization in Czechoslovakia is often perceived as a grey „Eastern iceberg“ where life stood still and uniformity governed. My analysis of sexological discourse, particularly of texts focused on perversity, juxtaposes the normalized ethos of the period with deviant sexual subjectivities. I analyze papers and debates presented at annual sexological conferences in the 1970s and 1980s. Sexuality, especially in its non -normal/deviant forms, was revealed as unstable, a quality sought to be „rectified“ through gender which was perceived as binary. The family was interrogated as a source of deviance and also as a place of redress. While sexological writings in general tend to biologize sexuality, my analysis shows that sexologists attributed social genealogy to deviance, a finding that attests to rigid social conditions during Normalization., Kateřina Lišková., and Obsahuje bibliografii

- Language:

- Description:
- The Morris water maze (MWM) is one of the most common tasks used to assess spatial learning and memory ability in rodents. Genetic strain and gender are two prominent variants that influence spatial performance. Although it was reported that ICR (Institute of Cancer Research) mice exhibited an unchanged baseline performance in the training phase of the MWM task, this outbred strain has been widely used in learning and memory studies, and little is known regarding the effects of sex on behavioral performance. In this study, we demonstrated that both male and female ICR mice could complete the MWM task. Furthermore, a significant sex difference was observed, with females having shorter escape latencies and longer durations in the target quadrant in both the acquisition and test phases. Our findings emphasize the necessity of careful examination of not only the strain effect on behavioral performance but also the sex effect., J.-F. Ge, ... [et al.]., and Obsahuje seznam literatury

- Subject:
- sex, spontaneously hypertensive rat, smooth muscle cells, cell proliferation, and thymidine incorporation
- Language:
- English
- Description:
- The growth capacity of cultured vascular smooth muscle cells (VSMC) obtained from the thoracic aorta of 8-week-old male and female spontaneously hypertensive rats (SHR) was compared. Explants from the intima- media complex were cultured in Dulbecco minimum essential medium supplemented with fetal calf serum (10 %). The migration of VSMC out of the explants started on day 2 in both sexes but on day 18 the number of explants with VSMC migration was 100 ±32 explants/flask in male VSMC and only 24 ±5 explants/flask in female ones. The doubling time at the early exponential phase of growth was shorter (13.5 ±0.5 h) and the p H]-thymidine Labelling Index was higher (34.0±2.3 %) in male VSMC than in those from females (19.9±0.6 h and 23.9±1.9 %, p<0.01, respectively). The difference in the doubling time became even more apparent in the late exponential phase of growth (male VSMC: 51.8±2.0 h, female VSMC: 91.5±5.8 h, p<0.001). Moreover, at the end of the exponential growth phase, the male VSMC reached significantly higher (pcO.OOl) maximum population density than VSMC from females. Our data provide evidence of different growth characteristics of cultured VSMC isolated from male and female SHR aortas.

- Description:
- Progesterone, estrogens, androgens and glucocorticoids all play important roles during pregnancy, from implantation to delivery. Focusing on selected steroid hormones in the peripartum period, we defined reference ranges measured using LS-MS/MS, and assessed relationships with maternal age, pregnancy weight gain, delivery type, and fetal sex. Samples were taken from 142 healthy women with physiological gravidity at the 37th week, during the first period of labor, and from newborn mixed cord blood. We found higher cortisol and 17-OH-pregnenolone plasma levels in mothers at the 37th week that carried male fetuses (p=0.03), but no significant differences in any studied hormones in newborns of different sex. Neither maternal age nor weight gain nor newborn birth weight had any relationships to any of the studied hormones. However, there were differences depending on vaginal versus planned cesarean section deliveries. In women carrying a male fetus we found significantly higher levels of 17-OH-pregnenolone, progesterone, cortisol, corticosterone and significantly lower levels of estradiol in those undergoing spontaneous vaginal delivery. However, we found no significant differences in the cord blood of newborn males from either delivery type. We established reference ranges for our analysis methods, which should be useful for further studies as well as in standard clinical practice., K. Adamcová, L. Kolátorová, T. Škodová, M. Šimková, A.
