Symmetrical cell division requires duplication of DNA and protein content to generate two daughter cells. Centrosomes also duplicate during cell division, but the mechanism controlling this process is incompletely understood. We describe an alternative splice form of SadB encoding a short SADB Ser/Thr kinase whose activity fluctuates during the cell cycle, localizes to centrosomes, and controls ce

Squamous cell carcinoma (SCC) of the skin is a tumor with greatly increased incidence among immunosuppressed patients; therefore, an infectious cause of SCC has long been sought. We performed a hospital-based case-control study of Staphylococcus aureus and biopsies of SCC (n = 82), basal cell carcinoma (n = 142), actinic keratosis (n = 57), and seborrhoeic keratosis (n = 72) in comparison with bio
Objective: The long-term suicide risk of depression was evaluated in a community sample by severity and gender. Method: The Lundby study is a prospective, longitudinal cohort study on a population consisting of 3563 subjects. In 1947-1997 medium or severe depression according to the Lundby diagnostic system were registered in 503 subjects. The same subjects were also diagnosed according to DSM-IV
Accurate determination of line parameters from weak absorption using two-tone frequency-modulation spectroscopy (TTFMS) with a GaAlAs diode laser is demonstrated. The air-broadening of three oxygen A-band lines is determined, using a least-squares fit. For a peak absorption of 1.3 x 10(-3) the deviation between the experimental and the fitted spectrum is less than 1%. The fitting procedure is succ
A major complication of multiple myeloma (MM) is the development of osteolytic lesions, fractures and bone pain. To identify genetic variants influencing the development of MM bone disease (MBD), we analyzed MM patients of European ancestry (totalling 3774) which had been radiologically surveyed for MBD. Each patient had been genotyped for ~600 000 SNPs with genotypes for six million common varian
På en lekplats eller i en nöjespark finns möjlighet att påtagligt uppleva begrepp från fysik och matematik med den egna kroppen. Med hjälp av tidsmätningar kan man få förståelse för gungans pendelrörelse och även en matematisk modell. Innehållet presenterades på matematikbiennalen i Umeå.
BACKGROUND: Balance impairment is one of the most distressing symptoms in Parkinson's disease (PD) even with pharmacological treatment (levodopa). A complementary treatment is high frequency stimulation in the subthalamic nucleus (STN). Whether STN stimulation improves postural control is under debate. The aim of this study was to explore the effects of STN stimulation alone on balance performance
Induction of broadly neutralizing antibodies, such as the monoclonal antibodies IgGb12, 2F5 and 2G12, is the objective of most antibody-based HIV-1 vaccine undertakings. However, despite the relative conserved nature of epitopes targeted by these antibodies, mechanisms underlying the sensitivity of circulating HIV-1 variants to broadly neutralizing antibodies are not fully understood. Here we have
By analysing N2 mice from a cross between the inbred C57BL strain B10.Q and the NMRI-related NFR/N strain, we recently identified a quantitative trait locus (QTL) influencing litter size. This locus is now denoted Fecq4, and it is present on the murine chromosome 9. In the present paper, we describe how the Fecq4 fragment originating form the NFR/N mouse strain will affect B10.Q mice by means of b
Granulocyte chemotactic protein 2 (GCP-2)/CXCL6 is a CXC chemokine expressed by macrophages and epithelial and mesenchymal cells during inflammation. Through binding and activation of its receptors (CXCR1 and CXCR2), it exerts neutrophil-activating and angiogenic activities. Here we show that GCP-2/CXCL6 itself is antibacterial. Antibacterial activity against gram-positive and gram-negative pathog
