  • I am very grateful to the special group of distinguished scientists who made up the Panel and Secretariat for this major review of the evidence on food, nutrition, physical activity and cancer. The vision of WCRF International in convening this Panel and confidence in letting a strong-willed group of scientists have their way is to be highly commended. In our view, the evidence reviewed here that led to our recommendations provides a wonderful opportunity to prevent cancer and improve global health. Individuals and populations have in their hands the means to lead fuller, healthier lives.

  • We present evidence that head-driven parsing strategies lead to efficiency gains over standard parsing strategies, for lexicalist, concatenative and unification-based grammars. A head-driven parser applies a rule only after a phrase matching the head has been derived. By instantiating the head of the rule important information is obtained about the left-hand-side and the other elements of the right-hand-side. We have used two different head-driven parsers and a number of standard parsers to parse with lexicalist grammars for English and for Dutch. ...

  • Immune system is composed of innate and adaptive responses and plays critical roles in cancer development and destruction. A century ago, Paul Ehrlich postulated that cancer would be quite common in long-lived organisms if not for the protective effects of immunity. About 50 years later, Burnet and Thomas proposed the concept of cancer immunosurveillance based on the experimental evidence of immune recognition of tumor antigens expressed on tumor cells (Dunn et al. 2004 ) . In 1971, the US Congress created a National Cancer Act – a War on Cancer.

  • The order of writing presented here highlights the importance of your results for defining the focus of your article. You should define the focus of your article based on the evidence you have. This way you can set the focus of your article relatively early and avoid unnecessary re-working when writing up the theory and other elements of the text. It is sensible to start writing an article by outlining the subject matter and content by a few bullet points or key words. This phase will act later as an aid in writing the introduction. After outlining the...

However, there is no experimental evidence to show a direct link between these sortases and sorting sequences.

  • Perceived quality of care is an important factor that determines whether people choose to utilise SRH services. Evidence from Bangladesh, Senegal and Tanzania suggests that in areas where women felt that they were receiving a high standard of care, they were more likely to use contraceptives than in areas with lower quality health facilities. Improving quality of care requires that patients’ perspectives and levels of satisfaction are taken into account when evaluating services, and are incorporated into policy decisions.

  • In the next section we outline some theoretical and empirical results about the relationships between monetary policy, the ináation target of monetary authorities, the level of this target perceived by the public and the long term interest rates dynamics. In section 3, we present the works of Kozicki and Tinsley (1998, 2001a, 2001b) and we establish the interest of this model in our framework.

  • In this review, we first describe the mechanisms by which the epidermal growth factor receptor generates a Ca 2+ signal and, subsequently, we com-pile the available experimental evidence regarding the role that the Ca 2+ ⁄calmodulin complex, formed after the rise in cytosolic free Ca 2+ concentration, exerts on the receptor.

  • DiGIR2 is the group I splicing-ribozyme of themobile twin-ribozyme intron Dir.S956-1,present in Didymiumnuclear ribosomal DNA. DiGIR2 is responsible for intron excision, exon ligation,3¢-splice site hydrolysis,and full-length intron RNA circle formation. We recently reported that DiGIR2 splicing (intron excision and exon ligation) competes with hydrolysis and subsequent full-length intron circularization. Herewe present experimental evidence that hydrolysis at the 3¢-splice site in DiGIR2 is dependent on structural elements within the P9 subdomain not involved in splicing....

  • The classical metabolic control theory [Kacser, H. & Burns, J.A. (1973)Symp.Soc.Exp.Biol. 27, 65–104; Heinrich, R. & Rapoport, T. (1974)Eur. J. Biochem.42, 89–95.] does not take into account experimental evidence for correlations between enzyme concentrations in the cell. We investigated the implications of two causes of linear correlations: competition between enzymes, which is a mere physical adaptation of the cell to the limitation of resources and space, and regulatory correlations, which result from the existence of regulatory networks....

  • The transmembrane topology of presenilins is still the subject of debate despite many experimental topology studies using antibodies or gene fusions. The results from these studies are partly contradictory and conse-quently several topology models have been proposed. Studies of preseni-lin-interacting proteins have produced further contradiction, primarily regarding the location of the C-terminus.
