Data concerning the persistent reduction of flow velocities measured by transcranial color-coded sonography (TCCS) in relation to the clinical and radiological outcome among patients with ischemic events in middle cerebral artery (MCA) territory is scarce. Patients with > or = 50% reduction of peak systolic velocities (PSV-MCA) as compared to the contralateral MCA were prospectively included in fo
CCND1 amplification results in cyclin D1 overexpression. However, other unidentified genetic mechanisms contribute to enhanced gene expression. In the present study, 32 squamous cell carcinoma of the head and neck (SCCHN) were investigated regarding chromosomal abnormalities involving 11q13 by cytogenetic analysis, genomic CCND1 amplification by differential PCR and FISH, and cyclin D1 expression
Annually laminated (varved) sediments from the River Angermanalven, mid-central Sweden, have been used to construct an annual 2000-year long record of varve thickness. Maximum daily annual discharge and mean varve thickness for the years 1909-1971 are significantly correlated (r = 0.87). A relationship between maximum daily annual discharge for the observed period (1909-1971) and varve thickness w
The molecular self-diffusion in concentrated aqueous mixtures based on an oppositely charged po ymer-surfactant pair has been investigated by NMR pulsed field gradient techniques. The investigated structures were an ordered cubic Pm3n phase (ca. 50 wt % water) and a disordered micellar phase, both containing cetyltrimethylammonium (CTA(+)) micelles with mixed acetate (Ac-) and polyacrylate (PA(-))
Aims: To explore the prevalence of overweight in men and women in a Swedish rural community and to examine its associations with all-cause mortality. Methods: A community-based cohort study. A total of 1,109 men and women aged ≥40 years participated in a survey of cardiovascular disease (CVD) risk factors in the city of Skara in Skaraborg, Sweden, in 1993—94. Overweight was defined as a BMI≥25.0 k
Benzimidazole units have been grafted onto a polysulfone (PSU) backbone via long alkyl thio–ether chains using a two-step procedure. In the first step, lithiated PSU was reacted with 10-undecenoyl chloride to graft PSU with undecenoyl side chains. The second step involved a free-radical thiol–ene coupling reaction between the C=C bonds of the pendant undecenoyl chains and 2-(2-benzimidazolyl)ethan
A 2-y nationwide survey of patients in Denmark with non-tuberculous mycobacteria (NTM) cultures was undertaken. Patients were identified by means of records held at the International Reference Laboratory of Mycobacteriology, Statens Serum Institut, Denmark. The objectives were to identify isolated NTM to species level, to describe the incidence of the various species and to evaluate the clinical s
BACKGROUND: Colorectal cancer (CRC) is one of the most common causes of cancer-related deaths in the Western world, and despite the fact that metastases are usually the ultimate cause of deaths, the knowledge of the genetics of advanced stages of this disease is limited. In order to identify potential genetic abnormalities underlying the development of local and distant metastases in CRC patients,
The effect of warmer climate on the depletion of snow-covered area has been evaluated for the Satluj River basin located in the western Himalayan region in India. Snowmelt runoff contributes substantially to the annual streamflow of this river. In order to study the impact of three warming scenarios (T+1, T+2 and T+3degreesC), more than 160 new snow depletion curves were prepared for different ele
Severely deficient activity of the von Willebrand Factor (VWF) cleaving metalloprotease,ADAMTS 13, is associated with thrombotic thrombocytopenic purpura (TTP). The mutation spectrum ofADAMTS 13 is rather heterogeneous, and numerous mutations spread across the gene have been described in association with congenital TTP. The 4143insA mutation is unusual with respect to its geographic concentration.
The objective of the study was to determine the influence of potato variety, weight and storage time after lifting on the glycaemic index (GI) and resistant starch (RS) content predicted from measurement of the rate and extent of in vitro starch hydrolysis, respectively. The potatoes were either boiled, or boiled and subjected to different heat-cycling conditions selected to promote retrogradation
Turner syndrome (TS) is caused by a sex chromosome aberration. The aim was to study the prevalence and incidence of thyroid disease in adults with TS. Women with TS (n = 91; mean age, 37.7 +/- 11 yr) were compared with an age-matched female random population sample (n = 228). At baseline, 15 (16%) TS women were treated for hypothyroidism, and elevated serum TSH was found in another eight (9%). As
BACKGROUND: Oxazolone-induced colitis in the rat is an immune-driven model of human colitis. The aim of the present study was to measure the changes in the absorptive and exudative permeabilites, oedema formation, and local blood flow in this model during the development of inflammation. We also assessed the effects of acute (<1 h), topical glucocorticosteroid (GCS) treatment on these factors. MET
Neuroinformatics is the information science infrastructure of neuroscience. It relates to the tools, databases, models and mechanisms of information flow that serve all of the clinical and research efforts in this field. There have been several attempts to create neuroinformatic systems, but none seem to have reached wide spread adoption yet. This is especially true in the in the area of cognitive
A flow injection analysis (FIA) system for specific determination of L-glutamate in food samples based on a bi-enzymatic amplification system has been developed. The content of L-glutamate in the sample was amplified by cycling between L-glutamate dehydrogenase (GIDH) and a novel enzyme, D-phenylglycine aminotransferase (D-PhgAT). In this system, GIDH converts L-glutamate to 2-oxoglutarate with co
In this work it is shown that domains of ordered dipoles are formed in large droplets made from dipolar particles provided that the dipole-dipole interaction between nearest neighbors is larger than the thermal energy. The size of the domains grows almost linearly with the size of the droplets for droplets containing 1000-30 000 particles. The largest domains occupy around 25-35% of the droplet vo
In 1995 and 1996 a Swedish feed mill had problems due to a persistent contamination of Salmonella enterica spp. enterica serovar Senftenberg that was difficult to eliminate. Forty-eight strains isolated from the feed mill, together with unrelated strains included to evaluate the discriminatory power and reproducibility, were analysed by pulsed-field gel electrophoresis (PFGE). The source of contam
It has been stated many times that the formation of radiation infringements in PbWO4 is to a big extent stipulated by the non-stoichiometry defects of the crystals, arising in the process of their growth and annealing. To refine the idea of characteristics of the non-stoichiometry defects and their effect on the radiation hardness of PbWO4, the current study is aimed at the melt composition infrin
The fate of ornithine in the nephron of the female OF-1 Swiss mouse remains unknown. The aim of the present study was to identify the nephron segments containing the key enzymes involved in ornithine metabolism: ornithine decarboxylase (ODC) and ornithine aminotransferase (OAT). Viable tubules isolated by microdissection were incubated with [1-14C]ornithine to study the oxidative pathway. Other tu
This dissertation argues that the English Protestant interpretations between 1845 and 1864 of John Henry Newman’s secession were related to the notions which formed part of the British national identity. It demonstrates how various writers modelled their interpretations of Newman’s secession on the beliefs of British anti-Catholicism. By understanding the British national identity as a common cult
