Energy consumption is today an important design issue for all kinds of digital systems, and essential for the battery operated ones. An important fraction of this energy is dissipated on the processors running the application software. To reduce this energy consumption, one may, for instance, lower the processor clock frequency and supply voltage. This, however, might lead to a performance degrada
Background. Umbilical artery Doppler velocimetry is a routine method for fetal surveillance in high-risk pregnancy. Uterine artery Doppler seems to give comparable information, but it can be difficult to interpret as there are two arteries, which might show notching and/or increased pulsatility index (PI) as signs of increased vascular impedance. Combining the information on vascular resistance on
BACKGROUND: The atherothrombotic risk pattern of the nephrotic syndrome resembles that of hyperhomocysteinemia. However, the effect of nephrotic range proteinuria on homocysteine metabolism has never been studied. METHODS: The study included 11 male nephrotic patients with idiopathic membranous nephropathy who underwent a treatment trial with adrenocorticotrophic hormone and 11 male non-nephrotic,
Objectives: Tumor-associated-trypsin inhibitor (TATI) is frequently coexpressed with trypsinogen in tumors. Recently, we found expression of trypsinogens in prostate cancer. We have now studied whether TATI is also expressed in prostate cancer and if TATI expression is associated with Gleason grade, proliferation, and neuroendocrine differentiation. Methods: Expression of TATI and prostate-specifi
A novel design of a biochemical oxygen demand (BOD) biosensor has been developed for on-line monitoring of easily biodegradable organic compounds in aqueous samples. The biological recognition element of the sensor could be easily renewed by injecting new bacterial paste without disassembling the sensor system. The sensor measurements were carried out in the initial-rate mode using a flow injectio
The mineralogy, petrology, and fluid inclusion chemistry of two charnockite patches within a distance of 4-5 km of the Varberg magmatic charnockite intrusion, SW Sweden, are investigated and described utilizing SEM, EMPA, and fluid inclusion microthermometry. Garnet-clinopyroxene (890-930 degrees C), garnet-amphibole (600-800 degrees C), and garnet-biotite (670-860 degrees C) Fe-Mg exchange thermo
The chemical and physical properties of secondary organic aerosol (SOA) formed by the photochemical degradation of biogenic and anthropogenic volatile organic compounds (VOC) are as yet still poorly constrained. The evolution of the complex refractive index (RI) of SOA, formed from purely biogenic VOC and mixtures of biogenic and anthropogenic VOC, was studied over a diurnal cycle in the SAPHIR ph
Abstract Objectives: The study aimed to test the construct validity, factor structure and reliability of the 11-item version of the Tampa Scale for Kinesiophobia (TSK-11, Swedish version) among older people (65+) with chronic pain. Design: Methodological study. Subjects: 433 participants with chronic pain (mean age 74.8, 65-98 years) completed postal questionnaires. 264 of the participants complet
Objective: To study serum type I interferon (IFN) activity in patients with early systemic sclerosis (SSc). Method: Serum type I IFN activity was measured in 33 consecutive patients with SSc and a disease duration of < 2 years and in 13 healthy individuals by calculating a type I IFN score according to the induction of six IFN-α regulated genes in a reporter cell line. Results: Twenty-seven per ce
Beta cell apoptosis is a hallmark of diabetes. Since we have previously shown that galectin-3 deficient (LGALS3/) mice are relatively resistant to diabetes induction, the aim of this study was to examine whether beta cell apoptosis depends on the presence of galectin-3 and to delineate the underlying mechanism. Deficiency of galectin-3, either hereditary or induced through application of chemical
Survival after in-hospital pulseless electrical activity (PEA) cardiac arrest is poor and has not changed during the last 10 years. Effective chest compressions may improve survival after PEA. We investigated whether a mechanical device (LUCAS (TM)-CPR) can ensure chest compressions during cardiac arrest according to guidelines and without interruption during transport, diagnostic procedures and i
Objective-Despite a wealth of experimental data in animal models, the independent association of insulin resistance with early carotid atherosclerosis in man has not been demonstrated. Approach and Results-We studied a European cohort of 525 men and 655 women (mean age, 44 +/- 8 years) free of conditions known to affect carotid wall (diabetes mellitus, hypertension, and dyslipidemia). All subjects
The interplay between diet and immune-parameters which could affect type 1 diabetes (T1D) pathogenesis is not sufficiently clarified. Intestinal upregulation of the activating receptor NKG2D(CD314) and its ligands is a hallmark of celiac disease (CD). However, the direct effect of gluten on NKG2D expression is not known. We studied, by FACS (lymphoid tissues) and RT-qPCR (intestine and pancreatic
Many functions of galectin-3 entail binding of its carbohydrate recognition site to glycans of a glycoprotein, resulting in cross-linking thought to be mediated by its N-terminal non-carbohydrate-binding domain. Here we studied interaction of galectin-3 with the model glycoprotein asialofetuin (ASF), using a fluorescence anisotropy (FA) assay to measure the concentration of free galectin carbohydr
Clinical management of lymphoplasmacytic lymphoma (LPL)/Waldenstrom macroglobulinemia (WM) has changed considerably over recent years, reflected in the use of new therapeutic agents (purine analogs, monoclonal antibodies, thalidomide- and bortezomib-based therapies). No population-based studies and few randomized trials have been performed to assess survival in newly diagnosed LPL/WM. We performed
Pancrustacea (Hexapoda plus Crustacea) display an enormous diversity of eye designs, including multiple types of compound eyes and single-chambered eyes, often with color vision and/or polarization vision. Although the eyes of some pancrustaceans are well-studied, there is still much to learn about the evolutionary paths to this amazing visual diversity. Here, we examine the evolutionary history o
Background: Accurate measurement of von Willebrand factor (VWF) is a critical requirement for the diagnosis of von Willebrand disease (VWD). Aim of the study: To evaluate the diagnostic efficiency of a rapid quantitative test for the measurement of VWF antigen (VWF:Ag) in type 1 VWD. Patients and methods: VWF: Ag was measured with an ELISA in a robotic instrument, as a reference method, and with a
Objective: Transplant arteriosclerosis (TA) restricts long-term survival of heart transplant recipients. Although the role of monocyte/macrophages is well established in native atherosclerosis, it has been studied to a much lesser extent in TA. Plasma cholesterol is the most important non-immunologic risk factor for development of TA but the underlying mechanisms are largely unknown. We hypothesiz
Popular Abstract in Swedish Alla levande celler har förmåga att känna av och på olika sätt anpassa sig till sin omgivning, antingen de ensamma utgör en hel organism eller är en av många miljarder celler i ett stort djur. Varje enskild cell kan bara ta emot en begränsat mängd olika sorters signaler och bara reagera på ett likaledes begränsat antal sätt. Den en- eller fåcelliga organismen är därmed The G protein-coupled receptors form one of the largest families of proteins involved in signalling between cells. It contains receptors for molecules as diverse as biogenic amines, glycoproteins and enzymes. The manuscripts included in this thesis together describe the initial characterisation of a previously unknown receptor of this class. A DNA fragment was cloned from a mouse genomic library.
