- Approaches exploiting trait distribution extremes may be used to identify loci associated with common traits, but it is unknown whether these loci are generalizable to the broader population. In a genome-wide search for loci associated with the upper versus the lower 5th percentiles of body mass index, height and waist-to-hip ratio, as well as clinical classes of obesity, including up to 263,407 individuals of European ancestry, we identified 4 new loci (IGFBP4, H6PD, RSRC1 and PPP2R2A) influencing height detected in the distribution tails and 7 new loci (HNF4G, RPTOR, GNAT2, MRPS33P4, ADCY9, HS6ST3 and ZZZ3) for clinical classes of obesity. Further, we find a large overlap in genetic structure and the distribution of variants between traits based on extremes and the general population and little etiological heterogeneity between obesity subgroups.

- This article aims to highlight how literary value is constructed today: how it is created and negotiated. It seeks to develop a perspective that considers the manifold and complex value-negotiation process. In accordance with Barbara Herrnstein Smith, the article argues that literary value is generated by a constant and continuous series of negotiations between production and sale: the institutions, groups of readers, and individuals who are part of the value-making process. A number of different values circulate among different stakeholders – trade, educational, aesthetic, personal, and so on – and the negotiations take place in accordance with the dictates of the respective needs, interests, and resources of these stakeholders. While Barbara Herrnstein Smith’s theories on literary value remain influential, they have rarely been tested empirically. The basic premise of the article is that the process of value creation has to be discussed from new perspectives based on empirical research. The article presents a case study of the Swedish author Sami Said’s literary debut – the critically acclaimed Väldigt sällan fin – and the negotiation process before and after its publication. The fact that Said was unknown at the time of his debut most likely foregrounded the visible negotiation of literary value in his case, but we believe that the process can be seen as an example of a continual and on-going practise in the literary sphere as a whole. The analysis shows that different agents claimed values and positions both in relation to the book and to each other. For example, marketing and publishing paratexts emphasised values of knowledge, institutionalised literary criticism valued the aesthetic qualities of the novel, while readers writing on the Internet took a more emotional and subjective position. The valuation also went back-and-forth between reading the novel as expressing a particular, non-Swedish experience with biographical overtones, and understanding it as manifesting universal existential values.

- While the risk for arterial vascular disease has been shown to be influenced by socioeconomic status (SES), there is limited information whether SES also influences the risk for venous thromboembolism (VTE). To evaluate whether there is an association between SES and VTE incidence. In 1990, all 730,050 inhabitants (379,465 women and 350,585 men) above 25 years of age in the County of Skåne in Sweden were evaluated with regard to age, household income, marital status, country of birth, number of years of residence in Sweden, educational level, and concomitant diseases. The cohort was hereafter prospectively investigated regarding diagnosis of, or death from VTE (deep venous thrombosis or pulmonary embolism ), during 1991-2003. The association between socioeconomic data and concomitant diseases at the baseline investigation 1990 and incidence of VTE during follow-up was examined by Cox proportional hazard models. During the 13 years prospective follow-up, 10,212 women and 7,922 men were diagnosed with VTE. In both genders, age above 40 years at baseline, low income, single status, and a lower level of education were associated with an increased risk of VTE. However, both men and women born outside of Sweden have a lower risk for VTE during follow-up, however. Age above 40 years, low income, single marital status, and lower level of education were independently related to an increased risk of VTE diagnosis during 13 years of prospective follow-up.

- BACKGROUND: Increasing evidence suggests that oral microbiota play a pivotal role in chronic diseases, in addition to the well-established role in periodontal disease. Moreover, recent studies suggest that oral bacteria may also be involved in carcinogenesis; periodontal disease has been linked to several cancers. In this study, we examined whether lifestyle factors have an impact on antibody levels to oral bacteria.METHODS: Data on demographic characteristics, lifestyle factors, and medical conditions were obtained at the time of blood sample collection. For the current analysis, we measured antibody levels to 25 oral bacteria in 395 cancer-free individuals using an immunoblot array. Combined total immunoglobin G (IgG) levels were obtained by summing concentrations for all oral bacteria measured.RESULTS: IgG antibody levels were substantially lower among current and former smokers (1,697 and 1,677 ng/mL, respectively) than never smokers (1,960 ng/mL; p trend = 0.01), but did not vary by other factors, including body mass index, diabetes, physical activity, or by dietary factors, after adjusting for age, sex, education, country, and smoking status. The highest levels of total IgG were found among individuals with low education (2,419 ng/mL).CONCLUSIONS: Our findings on smoking are consistent with previous studies and support the notion that smokers have a compromised humoral immune response. Moreover, other major factors known to be associated with inflammatory markers, including obesity, were not associated with antibody levels to a large number of oral bacteria.

UV-B Exposure of Indoor-Grown Picea abies Seedlings Causes an Epigenetic Effect and Selective Emission of Terpenes

- Terpenoids are involved in various defensive functions in plants, especially conifers. Epigenetic mechanisms, for example DNA methylation, can influence plant defence systems. The purpose of the present study was to investigate the influence of UV-B exposure on the release of terpenoids from spruce seedlings and on needle DNA methylation. Ten-week-old seedlings grown indoors were exposed to UV-B radiation during 4 h, and the volatile compounds emitted from the seedlings were analysed. Analysis of the volatiles 1, 3, and 22 d after this UV-B exposure showed that bornyl acetate, borneol, myrcene, and limonene contents increased during the first 3 days, while at day 22 the level of emission had returned to the control level. UV-B exposure decreased the level of DNA methylation in needles of young seedlings, reflected in methylation changes in CCGG sequences. Exposure of young seedlings to UV-B radiation might be a way to potentiate the general defensive capacity, improving their ability to survive in outdoor conditions. UV-B-induced defence is discussed in the light of epigenetic mechanisms.
