Deprenyl: from chemical synthesis to neuroprotection.

During the last decades (-)-deprenyl has become the golden standard of MAO-B inhibitors. It possesses dopamine potentiating and antioxidant properties; however, its effects cannot be explained solely by the enzyme inhibitory action. (-)-Deprenyl prevents the toxicity of certain selective neurotoxins and recently it was demonstrated to increase cell-cell adhesion as well. The complexity of its phar

Chromosomal aberrations in benign and malignant Bilharzia-associated bladder lesions analyzed by comparative genomic hybridization.

BACKGROUND: Bilharzia-associated bladder cancer (BAC) is a major health problem in countries where urinary schistosomiasis is endemic. Characterization of the genetic alterations in this cancer might enhance our understanding of the pathogenic mechanisms of the disease but, in contrast to nonbilharzia bladder cancer, BAC has rarely been the object of such scrutiny. In the present study, we aimed t

Transport of 222Rn using the regional model REMO : a detailed comparison with measurements over Europe

The 222Rn concentration simulated by the regional atmospheric modelREMOover Europe and western Siberia is compared to in-situ records in Europe, and discussed in the context of site effects for stations that are also part of a CO2 observing network. The REMO model has a limited spatial domain, forced at its lateral boundaries with meteorological fields of the European Centre for Medium-RangeWeathe

Molecular mechanisms of synaptic transmission and plasticity in spinal sensory pathways

Popular Abstract in Swedish Det är normalt, och oftast inget man reflekterar över, att en vävnadsskada (exempelvis ett hudsår) är förknippad med förhöjd smärtkänslighet. Denna delas in i två fenomen: hyperalgesi, en förhöjd upplevelse av smärtsamma stimuli, och allodyni, som innebär att ett vanligtvis milt stimulus, exempelvis lätt beröring, upplevs som smärtsamt. Hyperalgesi och allodyni är normaAn intense, potentially tissue-damaging (noxious) stimulus may lead to enhanced pain sensation of subsequent noxious stimuli (hyperalgesia) and to the perceiving of innocuous stimuli as painful (allodynia). This is thought to result to a large extent from strengthening of synapses established by primary afferent fibers onto spinal cord dorsal horn neurons. Here we investigated, using the postembed

Probing sd-fp Cross-shell Interactions via Terminating Configurations in 42Sc,43Sc

An experimental study of the lower fp-shell nuclei Sc-42,Sc-43 was performed via alpha pn and alpha p evaporation, respectively, from Ne-20 + Si-28 and Mg-24 + Mg-24 fusion-evaporation reactions. The experiments were conducted with the Gammasphere and Microball detector arrays. The level schemes of both nuclei have been extended considerably. Terminating states associated with the f(7/2)(n) and d(

Soaring flight in the Eleonora's Falcon (Falco eleonorae)

Eleonora's Falcon (Falco eleonorae) breeds in the Mediterranean region and is highly adapted for catching small birds on passage migration between Eurasia and their African winter quarters, which they feed their young. We studied gliding flight behavior of Eleonora's Falcon at a breeding colony located on a small island southwest of Sardinia, Italy. Gliding and soaring flight performance was measu

Miljöanalys med hjälp av kärnfysikalisk teknik - PIXE

Under de senaste tio åren har en känslig analysmetod för grundämnen utvecklats vid institutionen för kärnfysik vid LTH. Metoden kallas PIXE (Particle Induced X-ray Emisson) och medger att mycket små förekomster (109 – 1012 g) av grundämnen kanbestämmas i små prov. Metoden är snabb. Ett par minuters analys ger en samtidig bestämning av ett stort antal grundämnen. Analysmetoden används nu i ett stor

Ray-tracing analysis of diffractive-refractive X-ray optics

Ray-tracing simulations of mistuned sagittal diffractive - refractive X-ray lenses (DRXL) are presented. In this article, firstly the characteristic aberrations for various types of crystal misalignments within one-crystal and four-crystal DRXLs are considered, and the sensitivity of such an optical system to the mutual misalignment of its components is discussed. The simulations reveal that a DRX

DNA-ploidy in advanced gastric carcinoma is less heterogeneous than in early gastric cancer

This analysis of DNA-ploidy heterogeneity in advanced gastric carcinomas is consistent with the hypothesis of the emergence of a single aneuploid cell clone as a crucial mechanism in the progression from early gastric carcinoma to advanced gastric cancer. The prognostic value of DNA-ploidy in gastric cancers has been a matter of controversy. Tumour DNA-ploidy heterogeneity, the presence within the

The disciplinary effect of the single market on Swedish firms

In the 1980s it became increasingly clear that the European Community market was still segmented by national borders because of non-tariff barriers to trade. A major objective of the Single Market Program in 1992 was to remove these barriers, thereby enforcing intra-union competition. In this paper, a panel of Swedish firm-level data is used to evaluate whether domestic market power has been curta

BTKbase: XLA-mutation registry

X-linked agammaglobulinemia (XLA) is an immunodeficiency caused by mutations in the gene coding for Bruton's agammaglobulinemia tyrosine kinase (Btk). A new edition of the database (BTKbase) of Btk mutations has been compiled containing 282 patient entries representing 175 unique molecular events.

Comment on "Attenuation, of the intensity within a superdeformed band"

Sargeant et al. conclude from model calculations,in their paper [Phys. Rev. C 65 024302 (2002)] that the degree of chaos in normal deformed states does not enhance the decay out from the superdeformed band. We show that this conclusion is based on a rather unlikely assumption.
