Instructive cross-talk between neural progenitor cells and gliomas.

Gliomas are the most common primary brain tumors and offer a poor prognosis in patients because of their infiltrative and treatment-resistant nature. The median survival time after diagnosis is approximately 11-12 months. There is a strong need for novel treatment modalities in targeting gliomas, and recent advances use neural progenitor cells as delivery systems for different therapeutic strategi

Analysis of peripheral blood lymphocyte phenotype and function during dexamethazone treatment of progressive multiple sclerosis

Five patients with chronic progressive multiple sclerosis (MS) and three control patients with lumbar disc herniation were treated with dexamethazone during 14 days. The effect on peripheral blood T-cell subsets and on the proliferative response of peripheral blood mononuclear cells (PBMC) to pokeweed mitogen (PWM) and anti-mu antibody was analyzed. Before treatment, the proportion of CD3+ and CD4

On the Implementation of the Linearly Constrained Minimum Variance Beamformer

The linearly constrained minimum variance (LCMV) method, which allows multiple linear constraints, is an extension of the classical minimum variance distortionless response filter. Depending on the spatial filter length and the desired frequency grid, a direct computation of the resulting spatial beam pattern may be prohibitive. This brief exploits the rich structure of the LCMV expression to find

Protease activities in the chloroplast capable of cleaving an LHCII N-terminal peptide

Two protease activities of pea chloroplasts, one located in the stroma and the other associated to the thylakoid membrane, are described. Both proteases catalyse the endo-proteolytic cleavage of a peptide corresponding to the N-terminal loop and the first turn in helix-B of light-harvesting complex II (Lhcb1 from pea). The stromal protease cleaves preferentially on the carboxy-side of glutamic aci

Five Studies in Ethics and Gene Technology

I denna artikel kommenterar jag fem arbeten som alla behandlar modern genteknik ur etisk synpunkt, med hjälp av såväl teologisk som filosofisk etik. Böckerna tas som intäkt för att kortfattat diskutera några etiska problem i anslutning till genteknikens möjligheter, bland annat: Bör vi med genteknik skapa framtida människor med evigt liv? Hur kan vi fatta moraliskt välgrundade beslut som berör fra

Coronary heart disease mortality after 5 years of adjuvant tamoxifen therapy: Results from a randomized trial

From January 1, 1983, through December 31, 1992, a total of 4610 patients entered a randomized trial that compared mortality among patients receiving 2 years of adjuvant tamoxifen therapy with that in patients receiving 5 years of adjuvant tamoxifen therapy, 4175 of whom were recurrence free after 2 years of tamoxifen therapy. Among the 2046 patients randomly assigned to the 5-year group all-cause

Phase behavior of DOPE/TritonX100 (reduced) in dilute aqueous solution: aggregate structure and pH-dependence

The phase behavior of dilute mixtures of dioleoylphosphatidylethanolamine (DOPE) and reduced TritonX100 (TX100(r)) has been investigated at pH 7.4 and 10. Using simple turbidity measurements and optical observations, together with cryo-transmission electron microscopy (cryo-TEM), we estimate the phase boundaries. We show that at both pH 7.4 and 10, a very large amount of surfactant is needed for t

The Epistle of Jude : Its Text and Transmission

Popular Abstract in Swedish Avhandlingen behandlar det nytestamentliga Judasbrevets texthistoria. Monografin inleds med en översikt av textforskningen på de Katolska Breven i allmänhet och Judasbrevet i synnerhet, från 1800-talet och fram till nutid. Mot bakgrund av det tecknade forskningsläget beskriver så författaren studiens upplägg och syfte, samt antyder några av resultaten. Det handlar främsThis study treats the textual tradition of the Epistle of Jude. After an introductory survey of earlier text-critical research, the two main purposes of this investigation are formulated: to gather and to analyze the complete textual evidence of the Epistle of Jude. The first task, to gather the evidence, involves the collation of all Greek continuous text MSS of the Epistle of Jude. The evidence

ATPase activity associated with the magnesium chelatase H-subunit of the chlorophyll biosynthetic pathway is an artefact

Magnesium chelatase inserts Mg2+ into protoporphyrin IX and is the first unique enzyme of the chlorophyll biosynthetic pathway. It is a heterotrimeric enzyme, composed of I- (40 kDa), D- (70 kDa) and H- (140 kDa) subunits. The I- and D-proteins belong to the family of AAA(+) (ATPases associated with various cellular activities), but only I-subunit hydrolyses ATP to ADP. The D-subunits provide a pl
