Evidence of a possible association of cutaneous human papillomavirus (HPV) types, especially members of the genus Betapapillomavirus, and the development of non-melanoma skin cancer (NMSC) is accumulating. Vaccination with virus-like particles (VLPs) consisting of self-assembled L1, the major capsid protein, has been introduced to control anogenital HPV infection. This study examined the serologic
Alternative macrophage activation is implicated in diverse disease pathologies such as asthma, organ fibrosis, and granulomatous diseases, but the mechanisms underlying macrophage programming are not fully understood. Galectin-3 is a carbohydrate-binding lectin present on macrophages. We show that disruption of the galectin-3 gene in 129sv mice specifically restrains IL-4/IL-13-induced alternative
The estrogen receptor beta (ER beta) is emerging as an important player in the physiology of the endocrine pancreas. We evaluated the role and antidiabetic actions of the ER beta selective agonist WAY200070 as an insulinotropic molecule. We demonstrate that WAY200070 enhances glucose-stimulated insulin secretion both in mouse and human islets. In vivo experiments showed that a single administratio
A bulk of experimental evidence supports the idea that the stroke-damaged adult brain makes an attempt to repair itself by producing new neurons also in areas where neurogenesis does not normally occur (e.g., the striatum and cerebral cortex). Knowledge about mechanisms regulating the different steps of neurogenesis after stroke is rapidly increasing but still incomplete. The functional consequenc
The androgen receptor (AR) is the mediator of androgen actions. In the AR coding region there is a polymorphic CAG repeat encoding a stretch of the amino acid glutamine (Q). The repeat length modulates receptor activity and is normally distributed between 10-30 CAG with a median length of 22 repeats in white men. At the start of this work, a negative linear association between AR function and the
The interferon-inducible p53-target gene TRIM22 (Staf50) is a member of the TRIM (TRIpartite Motif) family. The TRIM family is a family of RING (Really Interesting New Gene) proteins, defined through a tripartite motif, containing a RING-domain, one or two B-boxes and a Coiled-coil-domain. The TRIM proteins are involved in diverse biological functions, such as apoptosis, cell-cycle- progression an
Background: For nuclei heavier than Pb-208 alpha decay is a dominating decay mode, and in the search of new superheavy elements one often observes chains of alpha decays. Purpose: Explore and test microscopic descriptions of alpha decay based on theories with effective nuclear interactions. Methods: The nuclear ground states are calculated with the Hartree-Fock-Bogoliubov (HFB) method using the Sk
Supported lipid bilayers are widely used for sensing and deciphering biomolecular interactions with model cell membranes. In this paper, we present a method to form supported lipid bilayers from total lipid extracts of Escherichia coli by vesicle fusion. We show the validity of this method for different types of extracts including those from deuterated biomass using a combination of complementary
An overview over the development and activities of the Centre for Research into Freemasonry and Fraternalism at the University of Sheffield, 2000-2010.
Renal transplant outcomes exhibit large inter-individual variability, possibly on account of genetic variation in immune-response mediators and genes influencing the pharmacodynamics/pharmacokinetics of immunosuppressants. We examined 21 polymorphisms from 10 genes in 237 de novo renal transplant recipients participating in an open-label, multicenter study [Cyclosporine Avoidance Eliminates Seriou
When the concept of multiculturalism was introduced to the Swedish national curriculum in the 1990's, a new democratic vision was added to the educational agenda: the school as a creator of a multicultural society. Based on a conceptual analysis of Swedish national curricula from 1962 until today, this study outlines how the concept of culture is subordinated to references of an “objective time”,
CYLD is a tumour-suppressor gene that is mutated in a benign skin tumour syndrome called cylindromatosis. The CYLD gene product is a deubiquitinating enzyme that was shown to regulate cell proliferation, cell survival and inflammatory responses, mainly through inhibiting NF-kappa B signalling. Here we show that CYLD controls cell growth and division at the G(1)/S-phase as well as cytokinesis by as
A Holocene sediment sequence from Lake Seukokjaure, a subarctic lake at tree-line in northern Sweden, was analyzed to assess major changes in the structure and functioning of the aquatic ecosystem in response to climate change and tree-line dynamics. The compiled multi-proxy data, including sedimentary pigments, diatoms, chironomids, pollen, biogenic silica (BSi), carbon (C), nitrogen (N) elementa
In this work we have calculated U from first principles for the early lanthanides (Ce-Gd) using the constrained random phase approximation (cRPA). We compare the static limit of U with experimental estimations from x-ray photoemission spectroscopy (XPS) and bremsstrahlung isochromat spectroscopy (BIS) spectra and also discuss the frequency dependence of U across the series. The localized subspace

Recent research has brought into focus the function of switching between verb forms and types of clauses, here labelled ‘gram switching’, as a device for marking non-main clause linking in various types of Arabic and in Biblical Hebrew (Persson forthcoming a; Isaksson, Kammensjö, and Persson 2009; Isaksson 2011, 2013). The study presented here shows that a switch, either in verb form/morphology or
BACKGROUND: In Saccharomyces cerevisiae galactose is initially metabolized through the Leloir pathway after which glucose 6-phosphate enters glycolysis. Galactose is controlled both by glucose repression and by galactose induction. The gene PGM2 encodes the last enzyme of the Leloir pathway, phosphoglucomutase 2 (Pgm2p), which catalyses the reversible conversion of glucose 1-phosphate to glucose 6
Hälsoeffekter av näringsämnen har traditionellt undersökts genom att analysera en eller ett fåtal fysiologiska markörer, exempelvis blodkolesterolnivå. Med nutrigenomik blir det möjligt att ta ett större grepp om hur kosten påverkar vår hälsa och även koppla det till individens genuppsättning.
