Abstract We found differences in administrative-territorial distributions of dermatoglyphics with regard to somatic healthy men of I adulthood with low and moderate levels intensity of caries. However, separate dermatoglyphics complexes of men with low levels intensity of caries, typical for any region of Ukraine, were not found. The data obtained from the western and southern regions of the country is particularly interesting. This, we believe, is a manifestation of population-regional particularities of the gene pool of Ukrainian men that corresponds to markers of greater physical health than to markers of the progression of the course of caries that is of low intensity. The greatest number of differences by indicator dermatoglyphics is evidenced in men with a medium level intensity of caries. This is concentrated in territorial segments: west↔center↔south and north↔center↔south. Moreover, a great amount of differences are seen in territorial segments: center west↔center↔north and south↔center↔east, while the least difference, albeit still numerous, is noticeable in territorial segments: north↔center↔east. The obtained data are interpreted by us as a manifestation of predisposition to the course of caries of a medium level of affection which is based on differences in the structure of the gene pool of the Ukrainian male population.

We examine how information asymmetry affects a firm's incentive to hedge versus speculate by using foreign currency derivatives. We find a quadratic relation between asymmetric information and a firm's risk management activities. In particular, we find that the firms facing medium level of information asymmetry are more likely to hedge, while firms with very high and low levels of asymmetric information tend to speculate. Moreover, we find that our results hold primary for firms operating in highly competitive industries.

ABSTRACT PfEMP1 is an antigenically variable molecule which mediates the adhesion of parasitized erythrocytes to a variety of cell types and which is believed to constitute an important target for naturally acquired protective immune responses in malaria. For 9 years we have monitored individuals living in an area of low-intensity, seasonal, and unstable malaria transmission in eastern Sudan, and we have used this database to study the acquisition, specificity, and duration of the antibody response to variant parasitized erythrocyte surface antigens. Both the levels and the spectrum of reactivity of these antibodies varied considerably among individuals, ranging from low levels of antibodies recognizing only few parasitized erythrocyte surface antigens to high levels of broad-specificity antibodies. In general, episodes of clinical malaria were associated with increases in the levels of parasitized erythrocyte surface-specific antibodies that subsided within months of the attack. This response was often, but not always, specific for the antigenic variants expressed by the parasite isolate causing disease. Our study provides evidence thatPalciparum falciparum malaria is associated with a short-lived, variant-specific antibody response to PfEMP1-like antigens exposed on the surface of parasitized erythrocytes. Furthermore, our data suggest that the antigenic repertoires of variant antigens expressed by different parasite isolates show considerable overlapping, at least under Sahelian conditions of low-intensity, seasonal, and unstable malaria transmission. Finally, we demonstrate the existence of persistent differences among individuals in the capacity to mount antibody responses to variant surface antigens.

Damaging Effects

Ultraviolet-B (UV-B: 280 to 320 nm) radiations have appeared to be detrimental to plants, due to their damaging effects on proteins, lipids, membranes and DNA. UV-B radiations are a significant regulator of plants’ secondary metabolites. High intensity of ultraviolet radiations may interfere with growth and productivity of crops. But low levels of UV-B radiations give rise to changes in the plants’ secondary metabolites such as phenolic compounds, carotenoids and glucoseinolates. Therefore, low intensity of UV-B radiations may be used to generate plants, enriched with secondary metabolites, having improved reproductive ability, early ripening and tolerance against fungi, bacteria and herbivores.

Low Intensity Exercise

Whole body lipid kinetics were evaluated during basal resting conditions, 4 h of treadmill exercise eliciting an oxygen uptake of 20 ml.kg-1.min-1, and 1 h of recovery in five untrained and five endurance-trained men. Glycerol and free fatty acid (FFA) rate of appearance (Ra) values in plasma were determined by infusing [2H5]glycerol and [1-13C]palmitate, respectively, and lipid oxidation was determined by indirect calorimetry. The lipolytic response to 4 h of exercise, expressed as the average glycerol and FFA Ra values, was similar in both trained (9.85 +/- 1.02 and 24.64 +/- 3.76 mumol.kg-1.min-1, respectively) and untrained subjects (11.29 +/- 0.99 and 24.13 +/- 0.39 mumol.kg-1.min-1, respectively). However, mean triglyceride oxidation was greater during exercise in the trained than in the untrained group (7.51 +/- 0.26 and 5.67 +/- 0.51 mumol.kg-1.min-1, respectively; P < 0.001). During recovery, glycerol and FFA Ra values decreased more rapidly in trained than in untrained subjects. We conclude that highly trained male endurance runners use more fat as a fuel during low-intensity exercise than do untrained healthy men despite similar rates of lipolysis and FFA uptake from plasma. Therefore, the increase in fat oxidation must be related to an increased percentage of FFA uptake oxidized, a greater contribution from intramuscular triglyceride stores, or both. Additionally, lipid kinetics return to baseline more rapidly in trained than in untrained subjects after completing an exercise bout of the same absolute intensity.

The fetal environment has been increasingly implicated in later psychological health, but the role of lipids is unknown. Drawing on the ethnically diverse Born in Bradford (BiB) birth cohort, the current study related levels of high-density lipoprotein (HDL), very-low-density lipoprotein (VLDL), and triglycerides in umbilical cord blood to 1,369 children’s teacher-rated psychosocial competence approximately 5 years later. Results of ordinal logistic regressions indicated that low levels of HDL, high levels of VLDL, and high levels of triglycerides predicted greater likelihood of being rated as less competent in domains of emotion regulation, self-awareness, and interpersonal functioning. Furthermore, these results generalized across ethnic background and children’s sex and were not accounted for by variables reflecting mothers’ psychological or physical health, children’s physical health, or children’s special education status. Together, these results identify fetal exposure to anomalous lipid levels as a possible contributor to subsequent psychological health and social functioning.

Increased concentrations of circulating insulin-like growth factor-I (IGF-I) or IGF-I relative to IGF-binding proteins (IGFBPs) are associated with increased risk of developing several forms of cancer. Conversely, exercise is linked with reduced risk. This study aims to investigate the effect of a low-intensity exercise program on circulating levels of IGF-I, IGFBP-1, and IGFBP-3, in previously sedentary males. Fourteen healthy men participated in cycle ergometer training at lactate threshold intensity for 60 min/day, 5 days/week for 6 weeks. After aerobic training, insulin sensitivity improved by 20%, while fasting insulin levels decreased by 13%. Simultaneously, low-intensity aerobic training decreased the circulating levels of IGF-I by 9%, while IGFBP-1 levels increased by 16%. An interesting finding was that higher pretraining level of IGF-I was associated with greater decline in IGF-I with training. Insulin-sensitizing low-intensity aerobic exercise is thus considered to be an effective method for downregulating IGF-I and upregulating IGFBP-1 levels.

A large-scale Medieval harbor site has been recently discovered at Nakazu-Higashihara in Masuda City, Chugoku region, Japan. The Medieval harbor site is divided into north and south areas. The concentration of 22 elements in soil samples from the north of the harbor site was determined in order to identify the geochemical signatures of the Medieval harbor site. The evidence described in the north area is an example of identification of both natural and anthropogenic processes that lead to geochemical variations within the archaeological soils. The north area of the site contains silt and sandy soils characterized by highest concentration of Zr and relatively low levels of most other elements (except for Sr and TS). Negative or weak positive correlations between TiO2 and MnO, and CaO and P2O5 in the north area indicate that this association of elements represents an ancient anthropogenic signature, especially related to residential sites in all soil types. Correlation between TiO2 and Ni, Y, Nb, Zr, Th, and Fe2O3 did not reflect the anthropogenic history. However, these elements and their ratios can be used to identify sources, as well as to establish baseline concentration of other elements which are influenced by anthropogenic and detrital inputs.

The objective of this study was to determine the prevalence and intensity of gastrointestinal nematodes in winter-slaughtered reindeer during 2002-2004, from northern reindeer herding cooperatives in Finland. Ostertagia gruehneri of the abomasum was prevalent with low levels of infections in 100% of calves, (n = 53; mean ≈ 1300 worms per animal) and in 98% of adults, (n = 41; mean ≈ 3900 worms per animal). There was no difference in the number of O. gruehneri between male and female calves. The proportion of O. gruehneri inhibited larvae was significantly higher in calves (81%) than in adult reindeer (39%) (P = 0.005). The intestinal nematodes, Nematodirus tarandi and Nematodirella longispiculata, were detected only in reindeer calves. The numbers of these worms did not differ between male and female calves, but there was a difference in abundance between sites. High prevalence and low intensity of gastrointestinal nematodes characterized the patterns of infection of the reindeer examined in this study. It is assumed that these infections are sub-clinical and would not contribute to productivity losses.Abstract in Finnish / Lyhennelmä:Ruuansulatuskanavan sukkulamatojen esiintyminen talvella teurastetuissa pohjoissuomalaisissa poroissa Tämän työn tavoitteena oli määrittää ruuansulatuskanavan sukkulamatojen prevalenssi ja tartunnan aste talvella teurastetuissa Suomen pohjoisten paliskuntien poroissa vuosina 2002-2004. Juoksutusmahan Ostertagia gruehneri –loisella oli korkea prevalenssi, mutta infektion aste (matojen lukumäärä) oli melko matala; 100% vasoista oli infektoituneita (n = 53; keskimäärin 1300 matoa mahassa) ja 98% aikuisista (n = 41, keskimäärin 3900 matoa). Juoksutusmahamatojen määrissä ei ollut eroja naaras- ja urosvasojen välillä. Kehityksessään estyneiden (pysähtyneiden) O. gruehneri –matojen osuus oli tilastollisesti merkitsevästi korkeampi vasoilla (81%) kuin aikuisilla poroilla (39%) (P = 0.005). Suolistosukkulamatoja Nematodirus tarandi ja Nematodirella longispiculata tavattiin ainoastaan vasoilla. Näiden matojen määrä ei eronnut naaras- ja urosvasojen välillä, mutta maantieteellisiä eroja yleisyydessä havaittiin. Tutkimuksen poroille leimallinen loisten korkea prevalenssi ja matala infektioaste viittaa oireettomuuteen ja siihen, että ne ehkä eivät aiheuta tuotantotappioita. Abstract in Norwegian / Sammendrag: Prosentvis forekomst (prevalens) av rundmark (nematoder) i mage-tarm fra vinterslakta rein i nordlige Finland Studien ble gjennomført på rein (Rangifer tarandus tarandus) fra nordlige reindistrikter i Finland i perioden 2002 til 2004. Rundmarken Ostertagia gruehneri fra løpemagen var vanlig og fantes i lavt infeksjonsnivå (dvs. i relativt lite antall) i alle undersøkte kalver (100% forekomst i 53 dyr med et gjennomsnittlig antall marker per kalv på ca 1300) og i 98% av de 41 undersøkte voksne dyrene der gjennomsnittet per voksent dyr var ca 3900 marker. Andelen med hvilende (inhiberte) larver var statistisk sannsynlig høyere i kalver (81%) enn i voksen rein (39%) (P = 0.05). Tarmnematodene Nematodirus tarandi og Nematodirella longispiculata fantes bare i kalver. Her varierte prosentvis infeksjon fra 25% til 100% i flokkene. Det var ingen forskjell i intensitet (antall mark) mellom han- og hunkalver. Høy prevalens og lav intensitet var det karakteristiske infeksjonsmønsteret i denne studien. Vi antar derfor at infeksjonene er ubetydelige (er subkliniske) og at de ikke vil bidra til produksjonstap.
