In aqueous systems with immobilized macromolecules, including biological tissue, the longitudinal spin relaxation of water protons is primarily induced by exchange-mediated orientational randomization (EMOR) of intra- and intermolecular magnetic dipole-dipole couplings. We have embarked on a systematic program to develop, from the stochastic Liouville equation, a general and rigorous theory that c

A rapid (6.5 min) and simple one-step magnetic immunoassay (MIA) has been developed for analysis of human urinary albumin in near patient settings. Polyclonal rabbit anti-human albumin was used as a capture antibody and monoclonal mouse anti-human albumin as a detection antibody in a two-site immunometric assay requiring no additional washing procedures. The polyclonal anti-human albumin was conju

Previous studies have suggested that the frequency of chromosomal aberrations (CAs), but not of sister chromatid exchanges (SCEs), predicts cancer risk. We have further examined this relationship in European cohorts comprising altogether almost 22,000 subjects, in the framework of a European collaborative project (CancerRiskBiomarkers). The present paper gives an overview of some of the results of

The pine sawfly, Diprion jingyuanensis Xiao et Zhang, is a serious pest of Chinese pine (Pinus tabulaeformis Carr.) in the northern parts of China. The general biology of this recently described sawfly species is little known and in the present study we used a synthetic pheromone to monitor its flight period and to evaluate the possibility to use pheromone traps as a tool for estimating and predic

Objective: Cerebral accumulation of amyloid beta (A beta) is a pathological hallmark of Alzheimer's disease (AD). Proteolytic processing of amyloid precursor protein (APP) by alpha- or beta-secretase results in two soluble metabolites, sAPP alpha and sAPP beta, respectively. However, previous data have shown that both alpha- and beta-secretase have multiple cleavage sites. The aim of this study wa

Amyloid β-protein (Aβ) sequence length variants with varying aggregation propensity coexist in vivo, where coaggregation and cross-catalysis phenomena may affect the aggregation process. Until recently, naturally occurring amyloid β-protein (Aβ) variants were believed to begin at or after the canonical β-secretase cleavage site within the amyloid β-protein precursor. However, N-terminally extended

Abstract Objective. Population-based data on the impact of bacterial infections on the course of compensated and decompensated cirrhosis as well as the occurrence, predictors of infection-related acute-on-chronic liver failure (ACLF) and its fatal outcome are limited. Material and methods. All patients with incident cirrhosis in the period 2001-2010, residing in an area of 600,000 inhabitants, wer

Background Trials of imatinib have provided evidence of activity in adults with Philadelphia-chromosome-positive acute lymphoblastic leukaemia (ALL), but the drug's role when given with multidrug chemotherapy to children is unknown. This study assesses the safety and efficacy of oral imatinib in association with a Berlin-Frankfurt-Munster intensive chemotherapy regimen and allo geneic stem-cell tr

Cancer of unknown primary (CUP) is a heterogeneous syndrome diagnosed at metastatic sites. The etiology is unknown but immune dysfunction may be a contributing factor. Patients with autoimmune diseases were identified from the Swedish Hospital Discharge Register and linked to the Swedish Cancer Registry. Standardized incidence ratios (SIRs) were calculated for subsequent CUP and compared with subj

Departure decisions of how and when to leave a stopover site may be of critical importance for the migration performance of birds. We used an automated radiotelemetry system at Falsterbo peninsula, Sweden, to study stopover behaviour and route choice in free-flying passerines departing on flights across the Baltic Sea during autumn migration. In addition, we had an offshore receiver station (FINO

Popular Abstract in Swedish Kostfiber visar på gynnsamma effekter på blodsockersvar, inflammationsmarkörer och blodfetter utifrån tre humanstudier som genomfördes i detta arbete. I en av studierna analyserades blod och urin med metabolomik. Det är en metod där man analyserar alla små molekyler (metaboliter) som finns i provet med hjälp av vätskekromatografi kopplat till masspektrometri. Med hjälp It is well-known that dietary fibre can have a positive effect on the development of lifestyle-dependent diseases such as cardiovascular disease and type 2 diabetes. However, the effect may be different for different kinds of fibre and different sub-populations at risk. Therefore, the effects of three different kinds of fibre on postprandial and long-term response in healthy subjects were investig

Abstract in UndeterminedThe capacity of shrub canopy water storage is a key factor in controlling the rainfall interception. Thus, it affects a variety of hydrological processes in water-limited arid desert ecosystems. Vast areas of revegetated desert ecosystems in Northwestern China are occupied by shrub and dwarf shrub communities. Yet, data are still scarce regarding their rainwater storage cap

In a society increasingly characterized by cultural heterogeneity and where trust issues are becoming ever more important, new demands and dilemmas arise related to organizations’ strategic communication. This study investigates the struggles of contemporary organizations to achieve credibility and strengthen their social legitimacy as actors in Sweden’s multicultural society. The empirical case c

To investigate why human immunodeficiency virus type 2 (HIV-2) is less virulent than HIV-1, the evolution of coreceptor usage, autologous neutralization, envelope sequence and glycosylation was studied in sequentially obtained virus isolates and sera from four HIV-2-infected individuals. Neutralization of primary HIV-2 isolates was tested by a cell line-based assay and IgG purified from patients'

Acute myeloid leukemia (AML) with inv(16)(p13q22) or the variant t(16;16)(p13;q22), is strongly associated with the FAB subtype M4Eo. A high incidence of CNS involvement was reported in the 1980s, but otherwise little is known about the pattern of extamedullary leukemia (EML) manifestations in this AML type. We have compiled clinical and cytogenetic data on 27 consecutive AML cases with inv(16)/t(

Bacterial colonization of the lower respiratory tract is frequently seen in COPD and may cause exacerbations leading to deterioration of the disease. An important part of the innate lung immunity is antimicrobial peptides, not least the cathelicidin hCAP-18/LL-37. Peptidylarginine deiminases (PADI) posttranslationally modifies proteins by converting cationic peptidylarginine residues to neutral pe

Numerous genetic factors that influence breast cancer risk are known. However, approximately two-thirds of the overall familial risk remain unexplained. To determine whether some of the missing heritability is due to rare variants conferring high to moderate risk, we tested for an association between the c.5791C>T nonsense mutation (p.Arg1931*; rs144567652) in exon 22 of FANCM gene and breast canc

Forecasts and analysis on real estate values and house prices are an ever-present problem for several different players. Often there is debate about the values of housing prices or housing bubbles in the Swedish cities. The difficulty with the valuation of housing, compared with other products, is their unique location. No housing is another comparable, and because of this there is no certain mark

This thesis analyses ten indepth interviews on domestic workers, class and gender roles with ten young, politically inclined and often adamantly feminist women towards the upper end of the Indian class spectrum. It aims to deepen the understanding of employerworker relations and gendered domestic roles in contemporary Indian households. Previous literature on the middletoupper class employers of d
