The experiment was performed on piglets, divided into control and experimental groups The experimental group received orally, from the birth to the 35(th) d of life, 0.4 g/kg b.w./d of L-alanyl-L-glutamine dipeptide (Ala-Gln). One week after weaning the piglets were killed and the small intestine and bones were sampled for histological analyses. Measurements of bone physical and geometric properti
Secretagogin is a newly identified calcium-binding protein selectively expressed in neuroendocrine tissue and pancreatic beta-cells. The function of secretagogin is unknown, but it has been suggested in beta-cells to influence calcium-influx, insulin secretion and proliferation, and has been observed downregulated in diabetes-prone BB rat islets exposed to cytokines. In the present study, we ident
Meningitis caused by Escherichia coli K1 is a serious illness in neonates with neurological sequelae in up to 50% of survivors. A high degree of bacteremia is required for E. coli K1 to cross the blood-brain barrier, which suggests that the bacterium must evade the host defence mechanisms and survive in the bloodstream. We previously showed that outer membrane protein A (OmpA) of E. coli binds C4b
Lyme borreliosis is a tick-borne disease often manifesting as a circular skin lesion. This cutaneous form of the disease is known as erythema migrans. In a 5-year follow-up study in southern Sweden, 31 of 708 individuals initially diagnosed with erythema migrans and treated with antibiotics were found to be reinfected with Borrelia burgdorferi. Although men and women were tick-bitten to the same e
The mechanical stress build up in fibre handling, the dynamical frictional phenomena between fibres and curves surfaces and formation of dust have been studied. Typical are stick slip behaviour and threshold stress levels for formation of dust. The emissions of dust can be limited by electrostatic charging. The measured coefficients of friction of the fibres depend on the mechanical properties, mi
As emphasized by Jeremy Bentham and the analytical school, logical consistency is a requirement for rational legislation. For understanding consistency between norms, a logical scrutiny of normative conflicts is needed. In our paper, a framework for the fine structure of such conflicts is introduced and explained. “Normative conflict” is defined relative the framework and different types of confli
Popular Abstract in Swedish Immunsystemet är vårt skydd mot främmande organismer såsom bakterier och virus. När vi får en förkylning, eller en infektion, tar immunsystemets celler hand om och dödar de invaderade mikroorganismerna. I normala fall märker vi endast av detta i form av att vi känner oss sjuka med eventuell feber som följd. Det ställs stora krav på immunsystemet. Det ska inte bara kunnaCollagen-induced arthritis (CIA) and pristane-induced arthritis (PIA) are animal models for human rheumatoid arthritis (RA), and can be induced in susceptible mouse and rat strains. CIA is induced by immunization of type II collagen (CII), a cartilage specific protein together with Freund’s adjuvant. PIA is induced by intradermal injection of pristane (2,6,10,14-tetrametylpentadecane). In rats, in
. Streptococcus pyogenes is an important human pathogen responsible for substantial morbidity and mortality worldwide. Although . S. pyogenes is a strictly human pathogen with no other known animal reservoir, several murine infection models exist to explore different aspects of the bacterial pathogenesis. Inoculating mice with wild-type . S. pyogenes strains can result in the generation of new bac
Myelodysplastic/myeloproliferative neoplasms, unclassifiable (MDS/MPN-U) are rare genetically heterogeneous hematologic diseases associated with older age and a poor prognosis. If the disease progresses into acute myeloid leukemia (AML), it is often refractory to treatment. To gain insight into genetic alterations associated with disease progression, whole exome sequencing and single nucleotide po
Introduction: Allergic rhinitis (AR) affects over 20% of the population of Europe and the United States. Allergen immunotherapy (AIT) is currently the only form of treatment that affects symptoms and modifies the progression of disease. Established forms of AIT include subcutaneous (SCIT) and sublingual (SLIT) immunotherapy and are widely effective, yet only 2-9% of eligible patients undergo thera
‘Transition’ was a concept used to denote that the former communist states in Europe were on the track towards establishment of a market economy in the wake of the collapsed planned economy. Another connotation of the concept was democracy – or democratisation – and a third, which was introduced when it became obvious that institutions were important for the transition to succeed, the Rechtsstaat,
The early host response to an infection is dependent on an efficient innate immune system. The human contact system once activated at a bacterial surface results in the induction of proinflammatory reactions and the release of antimicrobial peptides, However, under severe conditions its systemic activation A may evoke the generation of pathologic levels of kinins and a consumption of contact facto
The European Association of Urology non-muscle-invasive bladder cancer (NMIBC) guidelines recommend that all low- and intermediate-risk patients receive a single immediate instillation of chemotherapy after transurethral resection of the bladder (TURB), but its use remains controversial.
Popular Abstract in Swedish Ärftliga orsaker till ledgångsreumatism och Sjögrens syndrom Ett välfungerande immunförsvar är nödvändigt för att kroppen ska kunna mostå angrepp från virus, bakterier och andra mikroorganismer. Vid en autoimmun sjukdom tror man att immunförsvaret av misstag börjar angripa kroppens egna vävnader, vilket leder till att de förstörs. Hur dessa sjukdomar uppkommer känner mTo understand the pathogenesis of autoimmune diseases we have to consider the problem from different angles. Animal models provide a tool to further understand these complex diseases, as the influence of genetic and environmental factors could be limited. Moreover, modern transgenic techniques have made it possible to study the role of certain genes and gene products in the development of diseases
Popular Abstract in Swedish I cellen styrs allt av biomolekylernas förmåga till igenkänning och växelverkan med varandra. Molekylernas speciella egenskaper bygger upp kroppens alla komplicerade funktioner, till exempel immunförsvar, celldelning och muskelarbete. Interaktionerna mellan biomolekylerna kan vara av olika karaktär; de beskrivs som starka eller svaga (affinitet), långsamma eller snabba Molecular recognition and interaction is fundamental for the function of biological systems. The properties of the interacting biomolecules dictate the type of forces involved and the strength and dynamics of the interaction. Many interactions are very strong whereas others exhibit weak affinity. Typically, weak interactions work in concert to trigger a biological response. The advantage with thi
Infection with the Gram-negative pathogen Prevotella intermedia gives rise to periodontitis and a growing number of studies implies an association of P. intermedia with rheumatoid arthritis. The serine protease Factor I (FI) is the central inhibitor of complement degrading complement components C3b and C4b in the presence of cofactors such as C4b-binding protein (C4BP) and Factor H (FH). Yet, the
An anti-estradiol antibody with improved specificity is searched for by combining steroid analog binding studies, mutant antibodies obtained from a phage-display library and structural modeling. Three-dimensional models for the anti-estradiol antibody 57-2 were constructed by comparative model building. Estradiol and analogs were docked into the combining site and molecular dynamics simulation was
Background & objectives: We have earlier proposed that group A streptococcal (GAS) immunoglobulin binding surface proteins (IgGBPs) might trigger anti-IgG production and immune complex formation leading to glomerulonephritis. In the present study, cardiac tissue material from rabbits injected with heat-killed GAS was investigated. Methods: Rabbits were injected intravenously with 10(9) colony
