Popular Abstract in Swedish Ärfltiga faktorer orsakar ledgångsreumatism Reumatoid artrit (RA) även kallat ledgångsreumatism är en ledsjukdom som drabbar 1% av befolkningen, framförallt kvinnor. Orsaken till sjukdommen är inte känd, men man tror att det finns en ärftlig faktor som avgör om en viss individ kan utveckla reumatoid artrit eller inte. Den genetiskassociationen man idag vet om är till mThe immune pathology and MHC association of chronic arthritis was studied in three rat models for reumatoid arthritis (RA). Susceptible rat strains develop a T cell dependent chronic disease after immunization with rat collagen type II (CII). The LEW rat does not develop arthritis after immunization with rat CII, but a heterologous immune response to pepsin can break the tolerance to CII and rende

The measured water vapour resistances of clothing ensembles differ among laboratories particularly for impermeable clothing. Due to the moisture transfer in the clothing ensemble, evaporative heat losses in initial, transient and steady state phases are different. The purpose of this study was to investigate moisture absorption inside underwear and outer layer as a function of time, to quantify th

In order to compare measurements in different laboratories and with different models and measuring principles a small Round Robin test was suggested. 8 test institutions were able to join the study (with foot model sizes from 254 mm to 275 mm and test boot sizes from 41 to 44). We got also a declaration of interest from several other institutes that were not able to carry out the tests. A database

The chapter discusses problms of succession in the GCC states and how they are likely to impact regimes' responses to domestic and foreign demands for political reforms. It attempts to put succession issues in the context the emerging new order in the Gulf.

Dispossession and displacement have made their imprint on the lives of uncounted millions, and continue to pose the gravest threat to security for many more. The ascent of neoliberalism to global hegemony in recent decades – in all its multifarious and contextually path-dependent varieties – has radically changed the landscape of human vulnerability and security. Its successes in massive global an

How can we create sustainable agriculture, capable of feeding the soon to be 10 billion people of the earth, and at the same time preserve the ecosystems of the species that coexist with us on this planet? A team from Lund University in Sweden attempts to answer this tricky question.

In this study, a two-dimensional numerical model for water flow and solute transport, Hydrus-2D, was used to investigate the impact of landfill cover thickness and the antecedent water content (Ө) of the soil beneath the landfill on the chloride percolation below the landfill. Series of simulation scenarios were performed using season varying climatic data during a 30-year period including two var

Popular Abstract in Swedish Cellerna I vårt immunförsvar hjälper oss att eliminera olika typer av infektioner orsakade av parasiter, bakterier och virus. Ibland klarar dessa celler även av att ta bort tumörceller, kroppsegna celler som börjat att dela på sig okontrollerbart. Det måste betyda att cellerna i immunförsvaret kan se skillnad på kroppsegna celler och främmande celler och strukturer (antThe present study deals with natural killer (NK) T cells restricted to the antigen presenting molecule CD1d. NKT cells have been suggested to play a role in many diverse immunological situations such as clearance of different pathogens, protection against certain tumors, regulation of autoimmune reactions and as a link between innate and adaptive immune responses. NKT cells are in many respects un

A stability criterion for nonlinear systems, derived by the first author (2000), can be viewed as a dual to Lyapunov's second theorem. The criterion is stated in terms of a function which can be interpreted as the stationary density of a substance that is generated all over the state space and flows along the system trajectories towards the equilibrium. The new criterion has a remarkable convexity

This paper presents the first results of analyzing the functions of intonation and word order in Puyuma. Puyuma is an endangered Austronesian language spoken in Taiwan. As other languages of this branch, Puyuma is verb initial and displays variations in word order, so that VOS, SVO and VSO are attested. The aim of our study is to explain these word variations. We investigate the connection between

Mantle cell lymphoma (MCL) is an aggressive lymphoid malignancy for which better treatment strategies are needed. To identify potential diagnostic and therapeutic targets, a signature consisting of MCL-associated genes was selected based on a comprehensive gene expression analysis of malignant and normal B cells. The corresponding protein epitope signature tags were identified and used to raise mo

Stars ascending the red giant branch develop an inversion in mean molecular weight (mu) owing to the burning of He-3 in the region immediately above their hydrogen-burning shells. This inversion may drive thermohaline mixing and thereby be responsible for the extra mixing which is observationally indicated on the red giant branch. In this paper, we investigate the physical influences that determin

In cystic fibrosis (CF), colonization of the airways with Pseudomonas aeruginosa is associated with disease deterioration. The mechanism behind the disease progression is not fully understood. The present work shows that the antibacterial chemokine MIG/CXCL9 is present in the airways and in sputum of CF patients. MIG/CXCL9 showed high bactericidal activity against. P. aeruginosa, including some st

The present study aimed to investigate how the impact of several factors linked to geography would shape life-history traits in a gregarious species, using the pine processionary moth (PPM) Thaumetopoea pityocampa as a model system. PPM has a wide geographical distribution over the Mediterranean Basin, and it is a strictly gregarious species throughout larval development, where the total reproduct
