Temperature-dependent formation and photorepair of DNA damage induced by UV-B radiation in suspension-cultured tobacco cells

Two photoproducts of DNA damage, i.e. cyclobutane pyrimidine dimers (CPDs) and 6-4 photoproducts (6-4PPs), induced by UV-B radiation in suspension-cultured tobacco cells were quantified by enzyme-linked immunosorbent assay (ELISA) with monoclonal antibodies. CPDs and 6-4PPs were induced in tobacco cells by UV-B radiation. Photorepair of CPDs was faster than that of 6-4PPs. UV-B radiation induces f

Failure to detect mismatches between intention and outcome in a simple decision task

A fundamental assumption of theories of decision-making is that we detect mismatches between intention and outcome, adjust our behavior in the face of error, and adapt to changing circumstances. Is this always the case? We investigated the relation between intention, choice, and introspection. Participants made choices between presented face pairs on the basis of attractiveness, while we covertly

CEDAR

The CEDAR collaboration is developing a set of tools for tuning and validating theoretical models by comparing the predictions of event generators with data from particle physics experiments. CEDAR is also constructing resources to provide access to well defined versions of high-energy physics software and support for software developers. Here we give an overview of the CEDAR project and its statu

3,4-Dideoxyglucosone-3-ene (3,4-DGE): A cytotoxic glucose degradation product in fluids for peritoneal dialysis

Background. Bioincompatible glucose degradation products (GDPs) in fluids for peritoneal dialysis (PD) develop during sterilization and storage. Their biological activity has successfully been monitored through the use of various in vitro methods but their molecular and chemical nature is less well understood. Many GDPs are highly reactive carbonyl compounds. Although some of the identified GDPs a

The Rest on the Flight into Egypt: A motif in Scandanavian folk art

Although there is no biblical account of the 'Rest on the Flight into Egypt', the story is well known in the Christian world. In pseudo-Matthew the story has developed into legend form. He tells about the Christ-Child commanding the date palm Mary is resting beneath to bend down so that she can eat the fruit. It is found in literary sources from the twelfth century onwards. 'The Rest on the Flight

Surface chemistry of TiCl4 on clean and hydrogen modified W(110): identification of surface intermediates

The adsorption and decomposition of titanium tetrachloride (TiCl4) on W(110) were studied with high-resolution core level photoelectron spectroscopy. At least two stable intermediates are formed along the pathway to TiCl4 decomposition: TiCl4(a), which is stable up to 300 K, and TiCl3(a), which is stable up to 500 K. Successive adsorption at 80 K shows that the TiCl4() species forms in the presenc

Gråtens världar. Perspektiv på mäns tårar.

This study, based on interviews with army officers, focuses on crying as an action, creating meaning in our interpretation of the world. The discourse of male crying includes the image of a man wanting to express himself emotionally, but unable to because of the traditional ideal of self-control.

The dUTPases from herpes simplex virus type 1 and mouse mammary tumour virus are less specific than the Escherichia coli enzyme

The enzyme dUTPase catalyses the hydrolysis of dUTP to dUMP and pyrophosphate, thereby suppressing incorporation of uracil into DNA and providing a pool of dUMP, the precursor of dTTP. Hydrolysis of other nucleotides similar in structure to dUTP would conceivably be physiologically detrimental and high specificity of the reaction seems to be necessary. In this work, we characterize the substrate s

Etik och känslor : en empirisk studie av skuld- och medkänslor hos gymnasieelever – en prövning av Ortonys teori

Popular Abstract in SwedishEn del av Ortonys teorimodell angående den kognitiva strukturen hos emotioner testades på svenska gymnasieelever. Den del av teorin som användes i föreliggande studie handlade om de emotioner som tillskrivs den som utfört s.k. orätta handlingar. De eventuella känslor som man får när man utfört en orätt handling kallar Ortony för "self reproach" emotioner. Detta begrepp sThe purpose of this study was to test parts of Ortony's theoretical model relating to the cognitive structure of emotions in Swedish upper secondary school students. That part of the model, which was appropriate for the present study, deals with emotions attributed to the person who has perpetrated what is referred to as blameworthy actions. Ortony calls the possible emotions that you experience w

Binding of monoclonal IgM rheumatoid factor to streptococci via the antibody combining site

Radiolabelled monoclonal IgM rheumatoid factors, four from patients with type II essential cryoglobulinaemia and one originating from a patient with rheumatoid arthritis, were tested for binding to group A, B, C and G streptococci and Escherichia coli. Two of the preparations exhibited different binding patterns for the streptococci, whereas the remaining three were not reactive. The binding of on

Cages in tandem: Management control, social identity, and identification in a knowledge-intensive firm

Developments in organization studies downplay the role of bureaucracy in favour of more flexible arrangements and forms of organizational control, including socio-ideological control. Corporate culture and regulated social identities are assumed to provide means for the integration and orchestration of work. Knowledge-intensive firms, which typically draw heavily upon socio-ideological modes of co

Basic science of peripheral nerve repair: Wallerian degeneration/growth cone

Trauma to a peripheral nerve trunk is a complex injury because it involves not only repair processes locally at the peripheral level, but it also engages repair and compensation mechanisms at central levels. The main actor is the fascinating and unique neuron with its supporting cells, which consist mainly of Schwann cells. In the neuron and in the Schwann cells, intracellular signaling mechanisms

Nonparametric estimation of mixing densities for discrete distributions

By a mixture density is meant a density of the form pi(mu) (.) = f pi(theta) (.) x mu(d theta), where (pi(theta))(theta Theta is an element of) is a family of probability densities and mu is a probability measure on Theta. We consider the problem of identifying the unknown part of this model, the mixing distribution A, from a finite sample of independent observations from pi(mu). Assuming that the

Predictive factors of developing diabetes mellitus in women with gestational diabetes.

BACKGROUND: To investigate which factors during gestational diabetes pregnancies correlate with the risk of developing impaired glucose tolerance or diabetes 1 year postpartum and to compare this risk in women with gestational diabetes and women with a normal oral glucose tolerance test during pregnancy. METHODS: Of 315 women with gestational diabetes, defined as a 2-hr blood glucose value of at l
