Sammanfattning: En resultant-identitet för polynom i en variabel bevisas och används för att karakterisera SAGBI-baser för underalgebror genereradeThe thesis consists of an introduction and the following four papers: Paper I: Using resultants for SAGBI basis verification in the univariate polynomial ring. Authors: Anna Torstensson, Victor Ufnarovski and Hans Öfverbeck. Abstract: A resultant-type identity for univariate polynomials is proved and used to characterise SAGBI bases of subalgebras generated by two polynomials. A new equivalent

The objective of this follow-up study was to determine the long-term outcome of strictly classified cases of neuroborreliosis treated with antibiotics. A 1-y prospective population-based survey of Lyme borreliosis was conducted in southern Sweden between 1992 and 1993. A total of 349 identified cases with suspected neuroborreliosis were followed up 5 y later. Medical records were reviewed and all

Infection with high-risk human papillomavirus (HPV) has been implicated in the pathogenesis of esophageal squamous cell carcinoma, and up-regulation of telomerase in esophageal adenocarcinoma. We immortalized normal esophageal epithelial cells by over-expression of the HPV16 E6/E7 and human telomerase reverse transcriptase (hTERT) genes. HPV16 E6/E7-induced immortalization was accompanied by reduc

OBJECTIVES: Infectious agents like parvovirus have been implicated as exogenous factors that could trigger onset of systemic lupus erythematosus (SLE). A number of case reports describing a SLE-like presentation of acute human parvovirus B19 infection have been published, but no systematic investigation of the actual seroprevalence in epidemiologically defined SLE populations has previously been r

The HL-60 cell line, derived from a patient with acute promyelocytic leukemia, is a widely used model system to study the cellular and molecular events involved in differentiation of leukemic cells. In a screening for inducers of differentiation of HL-60 cells, cultures of Gliocladium strain 4-93 were found to produce Sch 52900, a previously isolated diketopiperazine (Chu et al,. J. Antibiotics 48

The reaction Ni-58(Ar-36, alpha-qp)88Mo has been studied at 145 MeV beam energy. A detector array consisting of the OSIRIS spectrometer, four charged-particle DELTA-E detectors and seven NE213 neutron detectors has been used to meaure the gamma radiation in gamma-gamma- and particle-gamma-gamma-coincidence mode. The level scheme of 88Mo has been extended up to 11.6 MeV excitation energy and probab

This note gives five applications of the eater-food interaction model (Garding 2005) where cycle length is a function of the eater average birth rate defined as the inverse of average life span. The model extends to an analysis of predator-prey-food cycles (Garding 2000). Here the cycle length is the same as that of en eater-food interaction whose average 'birth rate' is the sum of the average bir

The Stockholm Cancer Prevention Program is to our knowledge the first community intervention program in the world aiming of a reduction in the incidence of cancer. A community diagnosis model has been used in the planning. A thorough description of different organizations in the local communities of Stockholm has been made. A model for describing the organizations or collaborators has been worked

Försöken med förångning från vätskespill av aceton, dietyleter, etanol och metyletylketon och fördelning av brännbara ångor i dragskåp utförda med en inloppshastighet av ca 0.5 m/s visade att: mängden förångad vätska efter spill av olika vätskor vid olika initialtemperaturer kan förutsägas med god noggrannhet med befintliga dataprogram. Vid ett spill stannar den tunga ångan kvar i den nedre delen

1. It has been suggested that the vasoconstrictor response to neuropeptide Y (NPY) is located in the microvessels and that it increases with reduced vessel diameter. The aim of the present study was to analyse quantitatively, on the cat gastrocnemius muscle preparation in vivo, the effects of NPY on total regional vascular resistance (RT) and its distribution to large-bore arterial resistance vess

1. The mechanisms by which cooling inhibits insulin secretion were investigated by capacitance measurements of exocytosis in single mouse pancreatic B-cells maintained in short-term tissue culture. 2. A reduction of the bath temperature from 34 to 24 degrees C produced a gradual inhibition of exocytosis. Inhibition of exocytosis was use dependent rather than time dependent. The steady-state inhibi
