Gene expression profiling of human placentas from preeclamptic and normotensive pregnancies.
The aim of this study was to investigate patterns of gene expression in placental samples from patients with preeclampsia (PE), persistent bilateral uterine artery notching (without PE), and normal controls. This study included placental tissue from nine women with PE, seven with uncomplicated pregnancies and five with bilateral uterine artery notching in Doppler velocimetry tracings. Human cDNA m
Effects of a goal-oriented rehabilitation program in mild cognitive impairment: A pilot study
Background: Memory disturbance, deficient concentration, and fatigue are symptoms seen in amnestic mild cognitive impairment (MCI) as well as in mild traumatic brain injury (TBI). The aim of this study was to assess if an established rehabilitation program commonly used in TBI can aid MCI patients to develop compensatory memory strategies that can improve their cognition, occupational performance,

Nanotubes: The logical choice for electronics?
The demonstration of switches and logic devices made purely from carbon nanotubes, without the need for an external gate, puts nanotubes at the forefront of next-generation electronics.
Efficacy of maintenance treatment with naltrexone for opioid dependence: a meta-analytical review
Cutaneous sensory nerve fibers are decreased in number after peripheral and central nerve damage.
Two dermatologic patients displaying peripheral and central nerve damage, respectively, are described. Cutaneous nerve fibers in both patients were studied in skin biopsy specimens taken from neuropathic areas and from the contralateral side, immunocytochemistry being applied to a pan-neuronal marker, a protein gene-product (PGP 9.5). One of the patients, suffering from compression of the ulnar ne

Structural and functional studies of complement inhibitor C4b-binding protein.
C4b-binding protein (C4BP) is a potent inhibitor of the classical pathway of the complement system. This large plasma glycoprotein consists of seven identical a- chains and a unique b-chain held together by disulphide bridges. Both types of subunits are composed almost exclusively of complement control protein domains (CCPs). Using homology-based computer modelling and mutagenesis of recombinant p
Radiative Cycle with Stimulated Emission from Atoms and Ions in an Astrophysical Plasma
We propose that a radiative cycle operates in atoms and ions located ina rarefied gas in the vicinity of a hot star. Besides spontaneoustransitions the cycle includes a stimulated transition in one very weakintermediate channel. This radiative bottleneck creates apopulation inversion, which for an appropriate column density results inamplification and stimulated radiation in the weak transition. T
Biogas production from llama and cow manure at high altitude
Methane production from llama and cow manures from the Bolivian high plateau (The "Altiplano") was studied using a parallel reactor set-up consisting of 10 lab-scale biogasifiers. The effects of pressure (495 and 760 mmHg), temperature (11 and 35 degrees C), hydraulic retention time (20 and 50 days), and manure content in the slurry (10%, 20% and 50%) were evaluated with respect to productivity an
Combined hydrophobic-metal binding fusion tags for applications in aqueous two-phase partitioning
In this work, we studied the influence of fusion affinity tags containing both hydrophobic and histidines residues on the partitioning of the green fluorescent protein, GFPuv, in aqueous two-phase system. The tags were fused to the N-terminal of GFPuv and tested by immobilized metal affinity partitioning, in a PEG/salt system. The presence of both types of residues in the tag increased the partiti
Intranasal steroids decrease eosinophils but not mucin expression in nasal polyps
Increased mucin expression is a feature of nasal polyposis. Corticosteroids reduce polyp size and symptoms, but their effect on mucin production remains unknown. In this study, the effects of intranasal corticosteroids on MUC5AC mucin expression, nasal resistance, eosinophil and neutrophil infiltration, epidermal growth factor receptor (EGFR), interleukin (IL)-8, and tumour necrosis factor (TNF)-a
Surface sediment diatoms from the western Pacific marginal seas and their correlation to environmental variables
Diatom data of 192 surface sediment samples from the marginal seas in the western Pacific together with modern summer and winter sea surface temperature and salinity data were analyzed. The results of canonical correspondence analysis show that summer sea-surface salinity (SSS) is highly positively correlated with winter SSS and so is summer sea-surface temperature (SST) with winter SST. The corre
Protein self-association induced by macromolecular crowding: A quantitative analysis by magnetic relaxation dispersion
In the presence of high concentrations of inert macromolecules, the self-association of proteins is strongly enhanced through an entropic, excluded-volume effect variously called macromolecular crowding or depletion attraction. Despite the predicted large magnitude of this universal effect and its far-reaching biological implications, few experimental studies of macromolecular crowding have been r
A Structural Validation of an Inventory Based on the Abridged Five Factor Circumplex Model (AB5C)
We investigated the structural validity of an inventory from the International Personality Item Pool (Goldberg et al., 2006) that is based on the Abridged Five Factor Circumplex (AB5C) model. In a Swedish sample of 1,080 subjects using confirmatory factor analysis, we found that the majority of investigated facets had a primary loading on 1 of the 5 personality factors and a secondary loading on a
Polarity-tuned energy transfer efficiency in artificial light-harvesting antennae containing carbonyl carotenoids peridinin and fucoxanthin
This study focuses on the mechanisms and pathways of energy transfer in two carotenoid-pyropheophorbide dyads serving as an artificial light-harvesting antenna. The dyads contain carbonyl carotenoids peridinin (dyad 1) and fucoxanthin ( dyad 2). Studies of these carotenoids in solution showed a pronounced dependence of the excited-state lifetime on solvent polarity. This dependence was attributed

Radiology of the spleen
The spleen is generally not considered a challenge to the radiologist. Most often it poses a problem by anomalies or an irregular but normal contrast enhancement; however, a variety of inflammatory, infectious and neoplastic diseases may involve the spleen. CT and ultrasonography are screening modalities for the spleen. For problem solving, MR imaging can be helpful, especially due to its free cho
