Hollow fiber supported liquid membranes were applied for the passive extraction of phenoxy acid herbicides from water samples. Polypropylene hollow fiber membranes (240 mu m i.d., 30 mu m wall thickness, 0.05 mu m pore size, 30 cm length) were impregnated with 2.0% tri-n-octylphosphine oxide (TOPO) in di-n-hexyl ether in the pores of the fiber wall to form a liquid membrane. They were then filled
The human platelet cilostamide- and cGMP-inhibited cAMP phosphodiesterase (cGI-PDE) was rapidly purified approximately 19,000-fold to apparent homogeneity using single step affinity chromatography on the isothiocyanate derivative of cilostamide coupled to aminoethyl agarose. Within 24 h, 30 micrograms of enzyme protein was obtained from 20 ml of packed platelets. Vmax for cAMP and cGMP was 6.1 and
Invariant NKT cells (iNKT cells) are characterized by a semi-invariant TCR comprising an invariant a-chain paired with beta-chains with limited BV gene usage which are specific for complexes of CD1d and glycolipid Ags like a-galactosylceramide (a-GalCer). iNKT cells can be visualized with a-GalCer-loaded CD1d tetramers, and the binding of mouse CD1d tetramers to mouse as well as to human iNKT cell
Popular Abstract in Swedish Den här avhandlingen består av fem papper (A-E) som samtliga är tillämpningar av Rice's formel. Tillämpningsområdena är inom oceanografi och miljö. De tre första papperna behandlar egenskaper hos mötande havsvågor, det vill säga vågor som ett fartyg möter när det seglar på havet. Papper A syftar till att hitta en formel för att räkna ut intensiteten av sådana vågor. SpThis thesis is based on five papers (A-E), all treating various applications of Rice's formula. The areas of application are oceanographic and environmental problems. The first three papers treat properties of encountering waves, that is, waves that a ship encounters while sailing on the ocean. Paper A addresses the problem of computing the intensity of such waves and, in particular, the intensit
PURPOSE: A previous study has shown age- and sex-related differences in abdominal aortic compliance. In that study blood pressure determined by auscultation in the brachial artery was assumed to be equal to blood pressure in the abdominal aorta. To validate our findings we investigated the pressure-diameter (P-D) relationship of the abdominal aorta. METHODS: Diameter and pulsatile diameter change
Testicular germ cell tumours (TGCT) exhibit remarkable ability to differentiate into virtually all somatic tissue types. In this study, we investigated changes in mucin-type O-glycosylation, which have been associated with somatic cell differentiation and cancer. Expression profile of simple mucin-type O-glycans (Tn, sialyl-Tn, T), histo-blood group H and A variants and six polypeptide Ga1NAc-tran
Dynamic models complement existing time series of observations and static critical load calculations by simulating past and future development of chemistry in forest and lake ecosystems. They are used for dynamic assessment of the acidification and to produce target load functions, that describe what combinations of nitrogen and sulfur emission reductions are needed to achieve a chemical or biolog
Ectomycorrhizal (EM) fungi are known to colonize minerals in forest soil, and in many laboratory experiments it has been confirmed that EM fungi stimulate dissolution of minerals such as apatite, biotite and feldspars. However, due to the low number of experiments performed in the field, and in forests with different soil fertilities, it is difficult to conclude whether this effect has any ecologi
Depth data and bathymetry maps are used to analyze their association with tides, winds, currents and wave conditions in the port of Talara, at the coast of northern Peru. The objective is to investigate the processes that influence the sediment transport in the port. The sedimentation affects the saltwater pumps for fire fighting, obstructing them from delivering water since their operational wate
The idea of energy efficient, healthy buildings has existed since 1970s. However, a one-dimensional approach for many housing issues does not assure sustainability. Therefore, near the end of the 20th century, the built environment became a focus of attention within the environmental movement with wider focus on building certification schemes and sustainability issues such as interrelationships be
On their route to tropical Africa, European trans-Saharan migrants must cross two major geographical barriers, the Mediterranean Sea and the Sahara Desert, which necessitates the accumulation of large fuel loads. While northern Africa is the chief region where most migrants gain fuel for the Sahara crossing, Iberia is a target area to gain fuel before the sea crossing existing between Europe and A
Background. Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous group of B-cell lymphomas. Five clinical adverse risk factors are merged into the International Prognostic Index (IPI), which is the major tool for prognostication. In contrast to Hodgkin's lymphoma, gender is not considered as an adverse risk factor for DLBCL patients. As we clinically had observed a very good survival rate in y
P>Aims Type 1 diabetes mellitus (T1DM) is an autoimmune disease with potential mechanistic links to immune-related cancers. We aimed at examining the overall and specific cancer risks among hospitalized T1DM patients from the national registers in Sweden. Methods A T1DM research cohort was created by identifying T1DM patients from the Hospital Discharge Register and linking them with the Cancer Re
Background: Alzheimer's disease (AD) is associated with deposition of amyloid beta (A beta) in the brain, which is reflected by low concentration of the A beta 1-42 peptide in the cerebrospinal fluid (CSF). There are at least 15 additional A beta peptides in human CSF and their relative abundance pattern is thought to reflect the production and degradation of A beta. Here, we test the hypothesis t
BACKGROUND: Galectins, a family of small carbohydrate binding proteins, have been implicated in regulation of inflammatory reactions, including asthma and fibrosis in the lungs. Galectins are found in cells of the airways and in airway secretions, but their glycoprotein ligands there have only been studied to a very limited extent. METHODS: Bronchoalveolar lavage (BAL) fluid from mild asthmatics a
This thesis aimed to investigate possibilities to utilize death certificates in cancer epidemiology by analyzing nationwide databases from Sweden. Excessive information is available when investigating causes of death in cancer patients, including comorbidities and metastatic patterns. We used the Swedish Family- Cancer Database, which includes data from e.g. the Cause of Death Register and the Can
