Popular Abstract in Swedish Varje dag bildas ca en biljon nya blodceller i en vuxen person. Eftersom blodceller är relativt kortlivade sker denna nyproduktion ständigt. Alla dessa celler härstammar från en sorts cell, multipotenta blodstamceller. Genom en gradvis mognadsprocess, genereras röda blodkroppar (erytrocyter), vita blodkroppar (granulocyter, lymfocyter och monocyter) och blodplättar (troProliferation, differentiation, and survival of hematopoietic stem cells and multipotent progenitor cells are regulated by cytokines and cell-cell interactions. Kit ligand (KL) and Flt3 ligand (FL) have pleiotropic effects, promotes survival, but are nonredundant. Using myeloid progenitor cell lines and mouse bone marrow-derived Lin- progenitors, we demonstrate that inhibition of phophatidylinosit

A new device for stopping or reducing potentially irritating or harmful emissions from surfaces indoors is described. The device is a surface emissions trap prototype and consists of an adsorbent sheet with a semipermeable barrier surrounded by two thin nonwoven layers. The trap may be applied directly at the source of the emissions e.g. at moisture-affected floors and walls, surfaces contaminated

Molecular imprinting technology has been successfully applied to small molecular templates but a slow progress has been made in macromolecular imprinting owing to the challenges in natural properties of macromolecules, especially proteins. In this review, the macromolecular imprinting approaches are discussed with examples from recent publications. A new molecular imprinting strategy, microcontact

Fluorinated quinolones exert their bactericidal activity by inhibiting bacterial type II topoisomerases. At therapeutic concentrations, quinolones superinduce interleukin-2 (IL-2) and interferon-gamma production by mitogen-activated human peripheral blood T lymphocytes. At the molecular level, a stronger activation of the nuclear factor AP-1 ('activator protein-1') is observed in cells incubated w

The Writer:
Sigrid Combüchen was born in Solingen in the German Ruhr territory 1942. Shortly after the War her family moved to Sweden. She is a Swedish writer and literary critic and has so far published seven novels, a collection of essays and a biography (on the Norwegian novelist and winner of the Nobel Prize in Literature 1920, Knut Hamsun). She received the 2004 Selma Lagerlöf Prize a

This paper deals with Kripke’s influential criticism of the view that mental states are physical in nature, i.e. that such states are identical with certain physical states or processes.

Grammatical structure of Indo-European (IE) languages may appear to be diverse, but it is in fact more systematic than one may think. What is significant in explanation is alignment, i.e. differences represent different stages in the alignment change from active one to accusative one. This means that the grammatical structure was earlier organised by aspectual differences between perfective and im

By understanding laws of nature as geometrical rather than linguistic entities, this paper addresses how to describe theory structures and how to evaluate their continuity. Relying on conceptual spaces as a modelling tool, we focus on the conceptual framework an empirical theory presupposes, thus obtain a geometrical representation of a theory’s structure. We stress the relevance of measurement pr
