Twenty patients with carcinoma of the pancreas identified with ultrasonography and/or CT and confirmed by histology, were examined with MR before and after administration of an oral super-paramagnetic contrast medium. Ten patients were examined after administration of the contrast medium through a duodenal tube. Ten patients drank the contrast medium mixed with a viscosity-increasing agent. Organ
Aims To examine the prognostic importance of weight-change in patients with coronary artery disease (CAD), especially following acute myocardial infarction (AMI). Methods and results In 4360 AMI patients (OPTIMAAL trial) without baseline oedema, we assessed 3-month weight-change, baseline body mass index (BMI), demographics, patient history, medication, physical examination, and biochemical analys
I denna rapport ges några bilder av ekonomen i Sveriges kommuner och landsting. Förhoppningen är att dessa bilder bl.a. kan ge ett bidrag till de egenskaper och roller som tilldelas sektorns ekonomer. Bilderna förmedlas av den volymmässigt största andelen av sektorns ekonomer, d.v.s. de ekonomer som kan sägas vara underordnade en ekonomichef eller förvaltningschef. En fjärdedel av de nästan 600 ek
Adaptive tracking of non-linear dynamic plants is currently an important area of research. The main difficulty being felt by the research community is the lack of a general modelling framework that can facilitate synthesis of a simplistic control law while being capable of providing accurate approximation of non-linear systems. In this study a novel technique based on the control-oriented U-model
PURPOSE: Helicobacter pylori is a human gastroduodenal pathogen associated with type-B gastritis and gastric cancer. Low gastric tissue antioxidant levels are believed to increase the risk of developing gastric cancer. We investigated whether dietary antioxidant levels protect against infection and type-B gastritis in H. pylori-infected guinea pigs. METHODS: Dunkin-Hartley guinea pigs infected for
This paper introduces a generalisation of the notion of singular value for Hilbert space operators to more general Banach spaces. It is shown that for a simple integral operator of Hardy type the singular values are the eigenvalues of a non-linear Sturm-Liouville equation and coincide with the approximation numbers of the operator. Finally, asymptotic formulas for the singular numbers are deduced.
Serum determinations of the glial protein S100B has been found to correlate with brain damage after cardiac surgery. Forty-eight hours and later after surgery, increased S100B levels correlates with the presence of brain infarction, and the extent of infracted brain tissue. S100B at this time-point has been shown to predict long-term outcome, higher S100B levels correlated with decreased survival.
Endometrial stromal sarcomas (ESS) are rare neoplasms with the capacity both to invade the myometrium locally and to give rise to extrauterine metastases. Cytogenetic abnormalities have been reported in 22 cases of ESS, mostly involving rearrangements of chromosomes 6, 7, and 17. The most characteristic translocation of this tumor type, t(7;17)(p15-p21;q12-q21), was recently shown to generate a JA
Industrial interventions that focus on increased productivity may impair the ergonomics, on a workstation or individual level. This paper presents a method that characterises work time consumption and physical work load of manual work, using video recordings synchronised with physiological measurements of, e.g. muscular activity, and postures. The underlying idea was that it is possible to amalgam
This article reconstructs a Hebrew version of the Gloria in Luke 1: 14 with its focus on the righteous remnant of Israel and then analyses the early versions in Greek, Latin, Syriac and Coptic. Finally it gives some later interpretations of the canticle in literature, art and music.
Adenocarcinoma of the small intestine (ASI) is a rare disease of unknown aetiology. The glutathione S-transferase M1 (GSTM1) enzyme catalyses the detoxification of compounds involved in carcinogenesis of adenocarcinoma of the stomach, colon and lung, including constituents of tobacco smoke. We investigated a possible interaction between the lack of GSTM1 enzyme activity and the carcinogenic compou
Diabetes is caused by an absolute (type 1) or relative (type 2) deficiency of insulin-producing beta cells. We have disrupted expression of the mitochondrial protein frataxin selectively in pancreatic beta cells. Mice were born healthy but subsequently developed impaired glucose tolerance progressing to overt diabetes mellitus. These observations were explained by impairment of insulin secretion d
Background: The association between nasal and bronchial symptoms, and the course of bronchial responsiveness and airway inflammation in house dust mite sensitive persistent rhinitis over a prolonged time period has not been thoroughly explored. Objective: To determine if nasal symptoms were associated with bronchial symptoms in persistent rhinitic subjects, and to assess their bronchial responsive
This study outlined the influence of a number of parameters affecting the emission rate from one of the largest sources of VOC in the building stock in the Nordic countries. This source is flooring systems of polyvinyl chloride or linoleum attached to a substrate of moisture damaged or insufficiently dried concrete. The secondary emission rate of degradation products was measured, with the Field a
We present statistical evaluations of wideband spatial dual-polarized radio channel measurements. Some 80 different street-level transmitter positions in downtown Helsinki, Finland, were measured. We chose three different receiver array sites below, at, and above the roofop level of the surrounding urban environment. A super-resolution algorithm allows the determination of the directions of arriva
The aim Of this Study was to determine the effects of dexamethasone (Dex) and alpha-ketoglutarate (AKG) oil the total cholesterol, glucose, Na+, Cl-, total Ca and K+ levels, in serum for newborn and neonate piglets. The blood samples were collected from newborn non-suckling piglets born by sows administered front the 91(st) d of pregnancy to the parturition With AKG and/or Dex (AKG-0.4 g/kg b.w./e
