Compression of the lower trunk of the brachial plexus by a cervical rib in two adolescent girls: case reports and surgical treatment.

ABSTRACT: Presence of a cervical rib in children is extremely rare, particularly when symptoms of compression of the lower trunk of the brachial plexus occur. We present two cases with such a condition, where two young girls, 11 and 16 years of age were treated by resection of the cervical rib after a supraclavicular exploration of the lower trunk of the brachial plexus. The procedure led to succe

Grått, tråkigt, totalkriminellt? Diplomatiska beskrivningar av Polen – en fallstudie

Den omtalade globaliseringen förknippas inte bara med snabba finansiella rörelser utan också med ökat antal möten mellan etniska och nationella grupper. Beskrivningen av en sådan ökad kommunikation är ett stående inslag i såväl debatt (Martin & Schumann 1997) som samhällsvetenskaplig teoridiskussion (Bauman 1998, Beck 1998). Samtidigt anses det etniska identitetsbegreppet ha försvagats eller f

The Icelandic noun phrase: central traits

Since Abney (1987), generative syntax has invested much interest in the structure of the Noun Phrase, producing numerous theoretical as well as descriptive studies. Within the field of Scandinavian Noun Phrase studies, Delsing (1993) was a groundbreaking work that has since been followed up by several important studies, including Vangsnes et al. (2003) and Julien (2005). This field of inquiry is e

The earliest thymic T cell progenitors sustain B cell and myeloid lineage potential.

The stepwise commitment from hematopoietic stem cells in the bone marrow to T lymphocyte-restricted progenitors in the thymus represents a paradigm for understanding the requirement for distinct extrinsic cues during different stages of lineage restriction from multipotent to lineage-restricted progenitors. However, the commitment stage at which progenitors migrate from the bone marrow to the thym

Porous Silicon -an enzyme coupling matrix for micromachined reactors

Popular Abstract in Swedish Avhandlingen beskriver forskningen kring miniatyriserade enzymreaktorer - nyckelkomponenter i system för diabetsövervakning. Målet är att systemet kontinuerligt och under flera dagar skall kunna mäta glukosstatus hos bäraren. Provtagningstekniken för systemet är mikrodialys; en prob instucken i bukfettvävnaden ger ett prov som innehåller glukos. Analysen av detta prov sThe development of a miniaturised silicon wafer integrated enzyme reactor is described. The reactor was micromachined by anisotropic wet etching of (110) silicon. The enzyme glucose oxidase (GOx) was coupled to the reactor surface with standard methods of immobilising enzyme to silica. The glucose turn-over rate was monitored following a colourimetric assay. The advantage, in terms of high surface

Porous Silicon Microbioreactors - Applications and Technology

Microfluidic systems have become one of the most interesting fields in the research of chemical analysis. Miniaturized systems exhibit numerous practical advantages when compared with traditional batch-scale synthesis such as lower sample volumes, increased control of the reactions and higher sample throughput. This thesis describes the development and applications of a parallel channel microreact

Hyperbolic systems with relaxation: characterization of stiff well-posedness and asymptotic expansions

The Cauchy problem for linear constant-coefficient hyperbolic systems ut + ∑j A(j)uxj = (1/δ)Bu + Cu in d space dimensions is analyzed. Here (1/δ)Bu is a large relaxation term, and we are mostly interested in the critical case where B has a non-trivial null-space. A concept of stiff well-posedness is introduced that ensures solution estimates independent of 0 < δ 1. Stiff well-posedness is charact

MACIS: Minimisation of and Adaptation to Climate Change Impacts on BiodiverSity

The recently finished EU funded project MACIS reviewed observed and projected climate change impacts on biodiversity. It assessed mitigation and adaptation options. It also reviewed and developed methods to assess future impacts of climate change on biodiversity including the identification of policy options to prevent and minimise these impacts.

Murine monoclonal antibodies against murine uPA receptor produced in gene-deficient mice: inhibitory effects on receptor-mediated uPA activity in vitro and in vivo

Binding of urokinase plasminogen activator (uPA) to its cellular receptor, uPAR, potentiates plasminogen activation and localizes it to the cell surface. Focal plasminogen activation is involved in both normal and pathological tissue remodeling processes including cancer invasion. The interaction between uPA and uPAR therefore represents a potential target for anti-invasive cancer therapy. Inhibit
