    Opis:
    One of the variables oscillating seasonally in Helix pomatia L., described in our previous paper, was their rudimentary cryoprotection provided by modest increases in haemolymph glucose and glycerol concentrations in autumn and early spring, respectively. Because factors governing cryoprotective responses are unknown, we decided to investigate the effects of spring and autumn acclimation of H. pomatia to different thermal and photoperiod conditions on the changes in haemolymph concentrations of glucose and glycerol and on the glycogen level in selected organs. Neither acclimation to short-day photoperiod nor low ambient temperature evoked increase in glucose and glycerol concentration in spring and autumn. Both acclimation variants decreased hepatopancreatic glycogen level. The rudimentary freeze-tolerance in H. pomatia seems to be a combined effect of cold and short-day photoperiod and might also be affected by their nutritional and reproductive status. The effect of exposure to frost-bite is also likely to be involved.

    Opis:
    In the light of up-to-date epidemiological data concerning the prevalence of infertility, and also considering the scale of the problem of obesity and proven cause-effect relationship between abnormal body weight and infertility, it is justifiable to undertake the task of systematization of the state of knowledge concerning nutritional correlates of infertility, in order to create a scientific basis for the formulation of the assumptions of a fertility diet. The study is an attempt to systematize the current state of knowledge concerning the importance of energy and structural (qualitative) aspects of nutrition in the prevention and treatment of infertility.

    Opis:
    Introduction. Iodine deficiency is one of the most important public health problems in the world. It mostly affects pregnant women and children. The lack of iodine leads to an increase in the numbers of perinatal mortality and mental retardation. Materials and method. In 2012–2014, a survey was carried out of 2,342 women, of whom 2284 were analyzed for salt to measure the content of iodine, and 2,242 women of reproductive age had their urine samples analyzed by the ceriumarsenite method based on the Sandell-Kolthoff reaction. Determination of the medical and social effectiveness of biological monitoring of IDS was carried out in 3 stages. Results. The study revealed that in the eastern Kazakhstan region the relative risk (RR) of overall prevalence of iodine deficiency among women was 1.1 times higher (95% ID: 0.35–3.61; Z statistic = 0.192) among household respondents (≤15mkg/kg). In the Pavlodar region, the RR of the prevalence of total iodine deficiency is 0.5 times higher in households where the salt was not sufficiently iodized. In the Zhambyl region the RR of the iodine deficiency prevalence was about twice as high due to insufficient iodized salt. Conclusions. The introduction of biological monitoring of IDS among women, especially pregnant women, may positively affect the detection of the risk limits for the birth of infants with reduced mental abilities or other diseases during pregnancy, using timely targeted preventive measures to exclude factors that affect the spread of IDS.

    Opis:
    Introduction. The sharp decline in the total fertility rate in Poland coincided with broader socio-economic changes, which resulted in its reduction to the lowest level observed among the countries of Central and Eastern Europe. Objective. The aim of the study was to investigate and evaluate the changing patterns of reproductive behaviour in rural and urban areas, depending on the demographic and socio-economic features in Poland. Materials and method. Information about live births in Poland in the years 1995–2014 were obtained from the Central Statistical Office. Registered cases of live births in rural and urban areas were analyzed considering the maternal features (age, marital status, main source of income). To evaluate the changes in fertility and comparisons between rural and urban areas, Joinpoint Regresssion was used. Results. In 1995–2014, a shift in the age of highest fertility from 20–24 years to 25–29 years was observed. This occurred at the same time as a reduction in the fertility rate per 1,000 women aged 15–29 years, more pronounced in rural areas (95.8 to 60.0) than in urban areas (63.4 to 51.5), while in women aged 30–49 years, a faster increase in fertility was observed in urban areas (16.4 to 32.0) than in rural areas (27.5–29.2). Fertility trends between rural and urban areas differed significantly. A significant increase in live births for employed mothers was shown mainly in 2005–2009; later, the growth rate in rural areas was slower and in urban areas the growth trend stopped. Conclusion. The postponement of births and reduction of fertility in women aged 15–29 requires active measures aimed at creating favourable conditions for achieving economic independence for the younger generation, as well as combining work with raising children, especially in rural areas.

    Opis:
    Nieosiągalny wcześniej rozkwit badań genetycznych, zwłaszcza po finalizacji Projektu Sekwencjonowania Genomu Ludzkiego, stawia współczesną naukę, ale i społeczeństwo przed nowymi wyzwaniami. Jednym z istotnych jest określenie statusu uzyskiwanych w ramach tych badań informacji genetycznych. Niniejsze badania dotyczą formułowanego coraz częściej nakazu wymogu odpowiedzialności genetycznej w kontekście zadań rodzicielskich. Celem badań było wskazanie płaszczyzn takiej odpowiedzialności i konsekwencji wprowadzania jej w życie. W badaniach zastosowano metodę naukową desk research, a więc analizę danych zastanych, z uwzględnieniem dostępnych dokumentów, badań i publikacji, oraz ich konfrontację z normami bioetyki personalistycznej. Osiągnięte wyniki potwierdzają zarówno zmianę paradygmatu w podejściu do zdrowia, jak i poważne konsekwencje stosowania norm określanych jako odpowiedzialność genetyczna, jeśli zostaną one zaaplikowane do funkcjonowania rodziny w zakresie przekazywania życia, gospodarowania pozyskaną informacją genetyczną czy zarządzania ryzykiem genetycznym.
    The unavailable upsurge in gene research, especially after the completion of The Human Genome Project, presents new challenges for modern science and society. One of them is to determine the status of the genetic information obtained from these tests. The present research deals with the increasingly formulated demand for genetic responsibility in relation to parental tasks. The aim of these studies was to identify the areas of responsibility and the consequences of their implementation. The studies used the scientific desk research method, i.e. the analysis of the data found taking into account the available documents, studies and publications and their comparison with the norms of personalistic bioethics. The results confirm both a paradigm shift in health and the serious consequences of applying norms known as genetic responsibility when applied to the functioning of the family in terms of the transmission of life, the handling of genetic information or the management of genetic risks.

    Opis:
    This study investigated seasonal changes in the metabolic performance of spermatozoa and activity of the antioxidant enzymes in the seminal plasma of three wild boar/domestic pigs (aged 1.5 to 2.5 years) and the activity of the antioxidant enzymes in fluids of the cauda epididymidis and vesicular glands from 16 wild boar/domestic pig hybrids (aged 1 to 3 years). Parameters of the sperm metabolic activity, such as total motility, mitochondrial functions, and measurements of oxygen uptake, ATP content and L-lactate production, were analyzed during the spring-summer and autumn-winter periods. Besides these sperm metabolic parameters, the sperm membrane integrity was also assessed. Total protein content and activity of the antioxidant enzymes, such as superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx), were measured in the reproductive tract fluids. There were no marked significant differences (P > 0.05) between the seasonal periods in terms of sperm motility, mitochondrial function and oxygen uptake; however, spermatozoa collected during the autumn-winter period exhibited higher (P < 0.05) ATP content and L-lactate production than those harvested during the spring-summer period. It was found that the vesicular gland fluid exhibited a higher level of SOD activity during the spring-summer period compared with the autumn-winter period. Furthermore, CAT activity in the seminal plasma and vesicular gland fluid was greater during the autumn-winter. Total protein content was significantly higher in the vesicular gland fluid, whereas the cauda epididymidal fluid exhibited greater SOD and GPx activities, irrespective of the seasonal period. The findings of this study confirmed seasonal-related differences in the metabolic performance of spermatozoa and activity of antioxidant enzymes of the reproductive tract of the boar/domestic pig hybrids.
