A review is made of the basic tools used in mathematics to define acalculus for pseudodifferential operators on Riemannian manifolds endowed with aconnection: existence theorem for the function that generalizes the phase; analogueof Taylor’s theorem; torsion and curvature terms in the symbolic calculus; the twokinds of derivative acting on smooth sections of the cotangent bundle of the Riemannianm

Scaffold design remains a main challenge in tissue engineering due to the large number of requirements that need to be met in order to create functional tissues in vivo. Computer simulations of tissue differentiation within scaffolds could serve as a powerful tool in elucidating the design requirements for scaffolds in tissue engineering. In this study, a lattice-based model of a 3D porous scaffol

Chiral amines are important building blocks in the pharmaceutical industry, and the biocatalytic synthesis of these compounds using ω-transaminases has been increasingly studied in recent years. In principal, asymmetric synthesis of chiral amines from a prochiral ketone is the preferable route, but it is often hampered by an unfavourable equilibrium position and product inhibition. An effective me

Popular Abstract in Swedish Förekomsten av typ 1 (insulinberoende) diabetes före 15 års ålder har ökat under de senaste åren (Fig. 1) och barnen är allt yngre vid insjuknandet. Sjukdomen anses vara autoimmun, vilket innebär att kroppens eget immunförsvar angriper de insulinproducerande ?-cellerna i bukspottkörteln. En ärftlig benägenhet, som fr.a. är kopplad till s.k. vävnadsantigen på cellerna, mThe intention of this thesis was to investigate autoimmune markers for type 1 diabetes, together with signs of enterovirus infections during the pre- and perinatal period of life, and their possible association with the development of diabetes during childhood, adolescence, and young adulthood. We found that: 1. Newborns with ABO immunization, linked in epidemiological studies with heightened diab

Specimens of gastric mucosa and liver of 25 free-ranging Eurasian lynx (Lynx lynx), and four red foxes (Vulpes vulpes) shot in Sweden during 1999-2000, were investigated for the presence of Helicobacter species. Histopathology, bacteriologic culture and urease test, Helicobacter genus-specific 16S rDNA PCR analysis, and DNA sequence analysis were applied. Numerous Helicobacter-like organisms were

Popular Abstract in Swedish Njurfunktion inom hjärtkirurgi Akut njursvikt (AKI) efter hjärtkirurgi är en allvarlig komplikation som förekommer i 25-35 % av alla patientfall. AKI medför förhöjd risk för allvarliga komplikationer och död efter hjärtkirurgi. Ett stort fokus ligger på detektion, prevention och behandling av AKI och forskningsfältet uppdateras kontinuerligt. En rad olika läkemedel har Abstract Acute kidney injury (AKI) is a common and serious complication after cardiothoracic surgery and is associated with increased short- and long-term mortality risk. Despite extensive studies in the field, a comprehensive understanding of this syndrome has remained elusive, partly due to divergent definitions of AKI and partly due to the limitations of available routine biomarkers to predict,

Background. Most survival studies of the elderly population have set their baselines for first examinations between 60 and 80 years. The rapidly increasing numbers of exceptionally old persons call for knowledge about determinants of exceptional survival. Methods. The Swedish Centenarian Study followed 100 centenarians from the age of 100 to death of the entire cohort, by age I I I years. A biomed

This book is a contribution to the discussion about religion in contemporary Western society, characterized by the privatization of religion. The concept religion is not easily operational and does not carry meaning or implications that remain valid or consistent over time. It must be re-substantiated in order to remain descriptive and operational. This book’s ambition is to explore a means of re-

Abstract—Rhythmic movement of the arms while walking is an important feature of human gait. In this paper, we present an approach to analyze the movements of the arms while walking by using three wearable wireless devices placed around the torso. One of the devices is transmitter placed at the back and the other two are symmetrically placed receivers that record the power variation due to movement

Hematopoietic stem cells (HSCs) are thought to reside in discrete niches through stable adhesion, yet previous studies have suggested that host HSCs can be replaced by transplanted donor HSCs, even in the absence of cytoreductive conditioning. To explain this apparent paradox, we calculated, through cell surface phenotyping and transplantation of unfractionated blood, that similar to 1-5% of the t
