Popular Abstract in Swedish Stroke hos unga vuxna råttor och möss utlöser neurogenes i den skadade regionen striatum samt i den intakta hippocampus, men eftersom stroke framförallt drabbar äldre individer, är det av största vikt att utröna åldrandets effekt på hjärnans mekanismer för återhämtning. Gamla och unga vuxna råttor inducerades med stroke genom transient ocklusion av mellersta hjärnartäreStroke in young adult rodents triggers neurogenesis in the damaged striatum and intact hippocampus. as stroke happens frequently in aged individuals it is of great importance to know whether aging affects brain recovery mechanisms. Aged and young adult rats were subjected to stroke by transient occlusion of the middle cerebral artery and proliferating cells were labeled by intraperitoneal administ

The principal function of Saccharomyces cerevisiae Cdc13p is to provide a loading platform to recruit complexes that provide end protection and telomere replication. We isolated the Saccharomyces castellii Cdc13p homolog (scasCdc13p) and characterized the in vitro DNA binding features of the purified recombinant scasCdc13p. The full-length scasCdc13p binds specifically to G-rich single-stranded te

The response of a bacterial community to liming of a forest humus soil (pH 4.9 increased to pH 7.5) was studied in the laboratory at three temperatures (5, 20, and 30degreesC). As a comparison an unlimed soil (pH 4.9) and a soil limed in the field 15 years ago (pH around 6) were also included. The bacterial community tolerance of pH was measured using TdR incorporation. The pH of the bacterial sus

An instrument with integrated flow injection analysis (FIA) system has been developed for on-line monitoring a process for conversion of biomass under field condition. The instrument consists of a newly designed biosensor for easy renewal of the bio-receptor without disassembling the sensor, a FIA controller for controlling the analysis operations, and a computer-based data acquisition system for

Artikeln utgör en respons till ett föredrag om Derridas rättvisebegrepp, hållet av den isländske filosofen Björn Thorsteinson.

Type II collagen (CII) is the main protein component of cartilage and immune recognition of CII plays a critical role for the development of collagen induced arthritis (CIA), a widely used animal model for rheumatoid arthritis (RA). Antigen presentation is an important requirement for the immune response, the more efficient presentation of the antigen the better tolerance will be induced and ther

Invariant NKT cells (iNKT cells) are characterized by a semi-invariant TCR comprising an invariant a-chain paired with beta-chains with limited BV gene usage which are specific for complexes of CD1d and glycolipid Ags like a-galactosylceramide (a-GalCer). iNKT cells can be visualized with a-GalCer-loaded CD1d tetramers, and the binding of mouse CD1d tetramers to mouse as well as to human iNKT cell

An adaptive controller needs supervisoryfunctions in order to function well in an industrial environment.This paper describes these needs, and provides examplesof supervisory functions that presently are used in industrialadaptive controllers. These supervisory functions ensure thatadaptation only is performed when proper excitation is available.Supervisory functions that prohibit adaptation durin

In the third generation cellular networks and beyond, a wide variety of different services are/will be provided by the operators. Out of QoS reasons, it is preferable to give higher priority to certain connection types. These include calls carrying delay-sensitive services and already ongoing calls. In this paper, a prioritization method combining bandwidth borrowing and reservation, called BBR, i

Background The design of the Exeter stem may facilitate distal migration, but radiostereometric analysis (RSA) studies have been limited to 2 years of follow-up. Patients and methods We followed migration of the Exeter femoral stems in 22 primary hip arthroplasties for 5 years with RSA. Results All stems migrated distally and the median migration at 2 years was 1.34 mm, while at 5 years it was 1

We have used DNase I footprinting and fluorescence melting studies to study the interaction of the hairpin polyamide Im-Py-Py-Py-(R)(H2N)gamma-Im`-PY-PY-PY-beta-Dp with its preferred binding sites (5'-WGWWCW; W=A or T) and other sequences. DNase I footprinting confirmed that the ligand binds to the sequence AGAACA at nanomolar concentrations and that changing the terminal A to G causes a dramatic
