Monitoring the mycotoxins in food and their biomarkers in the Czech Republic

Testing of the presence of toxigenic microfungi and mycotoxins in foodstuffs in the food chain is an important part of the food safety strategy in The Czech Republic. At the national level, control of their presence in the entire food chain is assured by Public Health Protection Agencies, by the Veterinary Administration and by the Czech Agriculture and Food Inspection Authority. This article summarizes surveillance activities of Public Health Protection Agencies and mycotoxins findings in dietary raw materials and foodstuffs from the 1990s to 2004 in the Czech Republic. At present, the health risk from the mycotoxins exposure from foodstuffs is assessed to be relatively low in the Czech Republic, especially as far as the foodstuffs of the Czech origin are concerned. It may result in late toxic effects (e. g., carcinogenic risk) following a single or repeated ingestion of low mycotoxins doses from foodstuffs. Nevertheless, the overall situation may change due to the globalization of the food market. In order to minimize the risk associated with mycotoxins and eliminate their impact on Czech public health, continuous monitoring of the presence of toxigenic moulds, mycotoxins, and their biomarkers is necessary, in conjunction with strict respect to European Union legislation.

Gene and protein expression in the myometrium in pregnancy and labor

Microarray technologies widen our comprehension of the major structural and metabolic transformations which affect the myometrium from the very beginning of pregnancy until parturition. The results are coherent with the mass of information which was accumulated previously, primarily on the basis of studies of selected critical factors. They highlight the activation of precise signaling pathways, some of which may have been previously under evaluated. The remodelling and maturation processes that the myometrium undergoes in pregnancy appear clearly as phenomena which last during the full course of gestation. Comparatively, the onset of labor is perhaps the phenomenon which remains the least well described by these methods of analysis. Nevertheless, genomic studies constitute a necessary first step of orientation and help establishing new links between the generic signaling pathways that are activated during the normal or pathological gestation. These studies also represent an indicative step that will have to be paralleled, in the future, with the results of the systematic proteomic analysis of the myometrium.

Spatiality and the place of the material in schools

Drawing on a research study into the spatiality of teachers' workplaces, this article explores the 'concrete realities' of the artefact-filled world with which teachers, support staff and students interact, and considers the way in which networks of people and things order the spaces of the school. Spatiality is examined explicitly in terms of the relationship between different kinds of space and place, including the network space of relations and objects. In focusing on the relationship between the social and the material, and their implication in the construction of the everyday interactions that constitute the school, the article explores the utility of Actor Network Theories (ANT) as a means of reconciling the two without privileging one over the other or relegating objects to simple cultural or symbolic artefacts. A further challenge is to explore the spatialising force of objects as implicated in the active construction of social space, without resorting to simplistic behavioural determinism. The theoretical focus relates to the empirical concern: how particular spatial arrangements encourage or constrain ways of working together.

Dietary services in the homes for the aged in the Ukraine and the ways of their rationalization

On the basis of 7-day menu actual nutrition was studied in 39 old people's homes in the Ukrainian SSR in 1984-1985. The composition of the food rations was analyzed. It has been established that the nutrition in the old people's homes does not completely meet the requirements of the present-day science on nutrition for old age. High consumption of grain products, groats, maccaroni products and fats has been recorded along with insufficient consumption of vegetables, fruit, meat, fish and lactic acid products. The total amount of fat in the ration exceeds the values recommended more than by 60%; the level of simple carbohydrates is rather high, while that of animal protein is low. The authors have recommended a new balanced composition of products, meeting the current requirements of gerodietetics, enriched with food substances possessing geroprotective properties, that will promote normalization of metabolism in old subjects and prevention of age-dependent diseases.     

冬夏季基酒产量、质量动态分析

通过连续3年(2011~2013年)对酿酒车间12个试验生产班组冬夏季原酒产量、质量、原辅料消耗与出、入窖糟醅理化数据的整理分析,冬季按12个班组每年1月、2月、3月、12月4个月统计出所有以上生产数据的冬季平均值,夏季按每年6月、7月、8月、9月4个月统计出所有生产数据的夏季平均值,结果显示,严格按照传统固态酿酒生产工艺控制好关键要素,使12个试验班组的白酒产、质量稳步提高,消耗呈下降趋势。特别是对冬季酿酒生产效果明显,2012年和2013年冬季产量分别同比2011年冬季增长3.32%和5.73%;同时夏季生产波动减小,产质量稳定不掉排,特别是夏季产量波动同比均小于0.5%。使酿酒生产达到"冬不歇九,夏不歇伏",安全度过冬夏季的极端气候。     

Immunology and fertility in the bovine

Antibodies are powerful tools for unlocking normal physiological problems of both qualitative and quantitative nature that affect fertility. In addition, when antibodies are generated due to abnormal situations, fertility is depressed or completely inhibited for varying periods of time. Antibodies to sperm have demonstrated sperm membrane transformations that occur during spermatogenesis and spermiogenesis, the role of the blood-testis barrier, and the role of secretion and absorption in acquisition of sperm fertilizability. Antibodies to ovary have demonstrated factors controlling oocyte maturation, folliculogenesis, and the transudation of macromolecules into the follicle, Fallopian tubes, and uterus that affect capacitation, the acrosome reaction, sperm-oocyte interaction, fertilization, and implantation. Most hormone assays today are immune assays. Antibodies also can purposely suppress fertility (immunocontraception). Fertility problems can result from inappropriate antibody formation to sperm, oocytes, pregnancy products, or hormones. Fertility problems include auto-immune aspermatogenic orchitis, auto agglutination of sperm, autoimmune oophoritis, allergy to semen or egg yolk semen extenders, isoimmunization of female to sperm, fertilization failure, and embryo mortality due to maternal-fetal incompatibility.

Thallium in foods and the diet

Sources of thallium in food and normal levels of thallium in food are discussed. Information on dietary intakes of thallium in the UK is presented, current intakes are estimated to be about 0.005 mg/day. The dietary intake and published data on urinary excretion are consistent. It is considered that brassicae are likely to be the main source of dietary exposure to thallium in food produced on contaminated land.
