Recent evidence for efficient delivery of macromolecules, such as peptides and nucleic acids, from the cell exterior to the nucleus offers the interesting possibility of developing novel treatments directed at intranuclear targets. The findings should also stimulate the search for physiological ligands that utilize similar transport mechanisms to regulate pathobiological processes. Cytokines, grow
Proteinase 3 (PR3) is found in granules of all nentrophils but also on the plasma membrane of a subset of nentrophils (mPR3). CD177, another neutrophil protein, also displays a bimodal surface expression. In this study, we have investigated the coexpression of these two molecules, as well as the effect of cell activation on their surface expression. We can show that CD177 is expressed on the same
OBJECTIVE. To investigate the distribution and production of alpha 1-antichymotrypsin (ACT) and prostate-specific antigen (PSA) in benign hyperplastic and malignant prostatic tissue, respectively. METHODS. Using monoclonal anti-ACT and anti-PSA IgGs for immunocytochemistry and alkaline phosphatase conjugated 30-mer oligodeoxynucleotide probes for nonradioactive in situ hybridization, tissue specim
Background: To improve dosing consistency and product features, budesonide inhalation powder delivered via a dry powder inhaler (DPI) (DPI-A* 200 mu g) was redesigned to include lactose, a newly shaped mouthpiece, and a new dose indicator (DPI-B dagger). Budesonide CPI-B is available in two strengths (90 mu g, 180 mu g). Objective: To compare the relative rate and extent of the systemic availabili
This longitudinal study investigates the impact of social participation, trust and the combinations of social participation and trust on the incidence of first time acute myocardial infarction (AMI) in the population of Scania, southern Sweden. It is based on the cross-sectional 2000 public-health survey in Scania with a 59% participation rate and 13,604 participants, and prospective morbidity/mor
This study aimed to identify preclinical Alzheimer's disease (AD) in patients with mild cognitive impairment (MCI) using measurements of both regional cerebral blood flow (rCBF) and cerebrospinal fluid (CSF) biomarkers. Baseline rCBF assessments (133Xe method) were performed in 70 patients with MCI who were cognitively stable for 4–6 years, 69 patients with MCI who subsequently developed AD, and 3
OBJECTIVE: To evaluate the pathogenesis of metaplastic processes within the esophagus using a human model in which the exact duration of reflux was known. SUMMARY BACKGROUND DATA: The pathogenesis of Barrett's esophagus (BE) is incompletely understood. Patients undergoing esophagectomy and gastric tube reconstruction represent a good model for studying the pathophysiology of columnar cell metaplas
Conodont faunas from the Eoplacognathus pseudoplanus Zone in five main areas of Middle Ordovician rocks in Sweden are described and discussed and compared with faunas of comparable age from neighbouring areas. The investigation is based on 118 samples which together yielded 175 114 conodont elements. The Swedish conodont faunas are intermediate between shallower-water faunas from the eastern part
Core excitation from terminal oxygen O-T in O-3 is shown to be an excitation from a localized core orbital to a localized valence orbital. The valence orbital is localized to one of the two equivalent chemical bonds. We experimentally demonstrate this with the Auger-Doppler effect which is observable when O-3 is core excited to the highly dissociative O(T)1S(-)17a(1)(1) state. Auger electrons emit
Ultraviolet radiation around 302 nm was produced by sum-frequency generation in beta-barium borate employing a blue and a near-infrared diode laser. The diode-laser-based spectrometer has a mode-hop-free tuning range of 50 GHz and was used for high-resolution spectroscopic detection of sulfur dioxide. Differential measurements of several gas concentrations, at low pressure as well as at ambient at
The sign of the T-stress has been widely used for deciding whether directional stability prevails for straight cracks subjected to mode I loading under small scale yielding. However, there is little evidence for the reliability of such a criterion. On the contrary, it is shown that a local criterion is not applicable and that directional stability generally depends on body and load geometry as wel
The PHENIX experiment at the BNL Relativistic Heavy Ion Collider (RHIC) has measured electrons with 0.3 < p(T) < 9 GeV/c at midrapidity (y < 0.35) from heavy-flavor (charm and bottom) decays in Au + Au collisions at root s(NN) = 200 GeV. The nuclear modification factor R-AA relative to p + p collisions shows a strong suppression in central Au + Au collisions, indicating substantial energy loss of
Screening for gene copy-number alterations (CNAs) has improved by applying genome-wide microarrays, where SNP arrays also allow analysis of loss of heterozygozity (LOH). We here analyzed 10 chronic lymphocytic leukemia (CLL) samples using four different high-resolution platforms: BAC arrays (32K), oligonucleotide arrays (185K, Agilent), and two SNP arrays (250K, Affymetrix and 317K, Illumina). Cro
Objective: To design an economic model describing the costs and outcomes for patients treated with tumour necrosis factor alpha ( TNF alpha) inhibitors for rheumatoid arthritis ( RA) in current clinical practice in Sweden, to be used as a tool to estimate cost- effectiveness of the next generation of treatments. Methods: The model was constructed as a discrete event simulation ( DES) model analyse
Following the heavy-ion fusion-evaporation reaction S-32+Mg-24 at 95 MeV beam energy the lifetimes of analogue states in the T-z=+/-1/2 A=51 mirror nuclei Fe-51 and Mn-51 have been measured using the Cologne plunger device coupled to the GASP gamma-ray spectrometer. The deduced B(E2;27/2(-)-->23/2(-)) values afford a unique opportunity to probe isoscalar and isovector polarization charges and to d
In order to obtain a better understanding of the role of conformational disorder in the photophysics of conjugated polymers the ultrafast transient absorption anisotropy of partially deconjugated MEH-PPV has been measured. These data have been compared to the corresponding kinetics of Monte Carlo–simulated polymer chains, and estimates of the energy hopping time and energy migration distances for
he conservation process involves recognizing and listing rare and decreasing species, recording their distribution, biology and specific threats, proposing conservation programmes, and executing these programmes. There are large gaps in our knowledge about bryophytes which must be filled before their conservation can be selective. These include taxonomy, bryogeography, habitat demands, natural dy
