AIM: The goal of this study was to evaluate the incidence of myocardial infarction, cancer and death in relation to use of hormone replacement therapy (HRT). METHODS: Nine years' follow up of an urban cohort of peri-/postmenopausal women was undertaken. Local and national registers were used for retrieval of events. RESULTS: The incidence of myocardial infarction per 1.000 person-years in users an
This paper presents a model for reversed-phase purification of insulin from desamido insulin. The system is described by a reaction dispersive model with a competitive Langmuir isotherm. A model building and calibration method is presented and the model's region of validity is defined. The model is calibrated using only two-component experiments on the raw mixture by the inverse method and then ex
Helicobacter pylori exists in two different morphological forms, spiral and coccoid. This study demonstrated that both forms can infect BALB/c A mice. The animals were inoculated orally three times at 2-day intervals with 10(8) cfu of both spiral and coccoid forms of strain CCUG 17874 (NCTC 11637), strain 25 and strain 553/93. Infection was followed over a 30-week period by histological scoring of
Polarisation spectroscopy (PS) was used to probe CO2 gas concentration in a CO2/N-2 binary mixture at atmospheric pressure and ambient temperature. The CO2 molecules were probed by a direct laser excitation to an overtone and combination vibrational state. The tuneable narrow linewidth infrared laser radiation at 2 mum was obtained by Raman shifting of the output from a single-longitudinal-mode pu
Popular Abstract in Swedish Denna avhandling är ett resultat av ett doktorandprojekt vid Kvartärgeologiska avdelningen, Lunds Universitet. Syftet med avhandlingen har varit att utröna huruvida bildningen av kalktuff i Sverige har varit beroende av klimatet samt under vilka tider och i vilken närmiljö tuffen bildats. I samband med under-sökningen har ett stort antal landsnäckor påträffats och analyAlthough deposition of freshwater calcium carbonates, tufa, has occurred in large areas with carbonate soil or bedrock in Sweden, no tufa formation has been observed in Sweden. To better understand the factors controlling tufa formation in southern Sweden, bio- and lithostratigraphical studies were carried out on (paludal) calcareous tufa deposits in the province of Skåne. The biostratigraphical m
The DTMROC-S is a 16-channeI front-end chip developed for the signal processing of the ATLAS straw tube detector, TRT. Due to a highly radioactive environment, the chip is fabricated in a commercial 0.25μm CMOS technology hardened by layout techniques and, in addition, a special methodology was used to improve the circuit's robustness against Single Events Effects (SEE) caused by ionizing particle
Co-digestion of various wastes has been shown to improve the digestibility of the materials and biogas yield. Batchwise digestion of sisal pulp and fish waste was studied both with the wastes separately and with mixtures in various proportions. While the highest methane yields from sisal pulp and fish waste alone were 0.32 and 0.39 m(3) CH4/kg volatile solids (VS), respectively, at total solid (TS
Strain stability of plasmid-containing recombinant organisms is clearly important for industrial applications. Stability is normally assessed by methods such as selective colony forming units or by simply measuring the recombinant product. These methods are typically performed off-line, are time-consuming, and do not give detailed information on the changes in the metabolism. In the current work,
Genotyping of Chlamydia trachomatis is limited by the low sequence variation in the genome, and no adequate method is available for analysis of the spread of chlamydial infections in the community. We have developed a multillocus sequence typing (MLST) system based on five target regions and compared it with analysis of ompA, the single gene most extensively used for genotyping. Sequence determina
Solution phase synthesis of a constrained Leu(5)-enkephalin amide analogue 10 is reported, in which the cyclic ferrocenyl containing subunit 7 was introduced as a mimetic of the tetrapeptide Tyr-Gly-Gly-Phe unit. Temperature dependence of the chemical shift of the amide protons of 10 indicated a hydrogen bond between the same amino acid residues as observed for the natural Leu-enkepalin in the sin
This is the first report of the Twin Mom Study, an investigation. of three hypotheses concerning influences on maternal adjustment. These hypotheses concern the role of the marital and parent-child relationships in mediating genetic influences on maternal adjustment and on the importance of the mothers' marital partners as a specifiable source of influences on their adjustment not shared with thei
The degradation of technical toxaphene in water with two kinds of bioreactors operating in sequence was studied. One packed bed reactor was filled with Poraver(R) (foam glass particles) running at anaerobic conditions and one suspended carrier biofilm reactor working aerobically. Chemical oxygen demand (COD), chloride, sulphate, pH, dissolved oxygen, total toxaphene and specific toxaphene isomers
Superoxide dismutase (SOD) activities of various metallobacitracin complexes were evaluated using the riboflavin-methionine-nitro blue tetrazolium assay. The radical scavenging activity of various metallobacitracin complexes was shown to be higher than those of the negative controls, e.g., free transition metal ions and metal-free bacitracin. The SOD activity of the complex was found to be in the
A total of 47 firms joined the Swedish EKO-Energi programme between 1994 and 1997. This was a public voluntary programme devoted to promoting the environmental vanguard, while disregarding the rearguard. The programme offered free energy audits and the promotion of a label, in return for implementation of energy management. Audits covered some 5% of industrial energy consumption. The most clearly
This paper focuses on challenges in implementation of research in community-based occupational therapy practice. Based on a two-year project in a south Swedish municipality aiming at studying implementation of structured assessment procedures in the housing adaptation process, the first purpose is to provide a detailed project description, and the second is to report on first results identifying c
The effect of a second mutant allele (V1991, here denoted rn*) at the PRKAG3 (RN) locus on carcass composition was determined in 334 pigs, entire males and females, from crosses between Swedish Hampshire (H) and Finnish Landrace (L) (H x LH; LH x H; LH x LH). Pigs were classified according to DNA test into the following PRKAG3 genotypes: RN-IRN- (23%), RN-/rn(-) (24%), RN-/rn* (33%), rn(+)/rn(+) (
We have investigated terahertz (THz) emission due to dynamical electron transport in wide miniband GaAs/Al0.3Ga0.7As superlattices. By noting that the time-domain THz emission spectroscopy contains the information on the step response of the electron system to the bias electric field, the obtained THz spectra were compared with the high-frequency conductivities predicted for miniband transport. Ex
Summary The leaking of water through roofs is a major problem in many parts of Tunisia. As a part of a collaboration between "École N: ionale d'Ingénieurs de Tunis" (E.N.I.T.) and Lund University, Institute of Science and Technology (L.N.T.H.), Sweden, a measuring method has been developed to compare the watertightness of different roofing membranes. With the method, three roof structues with diff
BACKGROUND: The S-s-U- phenotype in African Americans is due to a GYPB deletion, however the molecular basis for the S-s-U+var phenotype is poorly understood. Variable reactivity of S-s-U+var RBCs with monoclonal anti-He or by anti-U has been demonstrated, however the underlying molecular bases for this phenotype remain to be established. STUDY DESIGN AND METHODS: Hemagglutination was performed on
