Recent studies have shown that ethanol exposure of reaggregation cultures of fetal rat brain cells causes an increased activity and amount of catalase, and also an increased activity of the oligodendrocyte marker enzyme 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNP). In the present study, reaggregation cultures were grown in the presence of 40 mM ethanol during 17 days, corresponding to a peri
A method for purification of recombinant apolipoprotein A1 in aqueous two-phase systems has been studied. A mutant of apolipoprotein A-I, the Milano variant, was expressed in E. coli. Phase systems containing ethylene oxide (EO)-propylene oxide (PO) random copolymers have been used. These polymers are thermoseparating and have the ability to separate into one water-rich and one polymer-rich phase
cAMP stimulation and Rho kinase inhibition are shown to decrease microvascular permeability during noninflammatory conditions, most likely by decreasing contractility of actomyosin filaments in the endothelial cell, but their effects on permeability during inflammatory conditions are not clarified. The objective of this in vivo study, performed on the autoperfused and denervated calf muscle of the
The influence of the reaction conditions on the enantioselectivity of reactions catalysed by lipases or hydroxynitrile leases (HNLs) in organic solvents was investigated. The lipases catalysed kinetic resolution of chiral secondary alcohol, or chiral carboxylic acids and the HNLs catalysed asymmetric addition of hydrogen cyanide to aldehydes. The temperature effects on enantioselectivity, were stu
Although many effects of gamma-aminobutyric acid (GABA) on retinal function have been attributed to GABA(A) and GABA(C) receptors, specific retinal functions have also been shown to be mediated by GABA(B) receptors, including facilitation of light-evoked acetylcholine release from the rabbit retina (Neal and Cunningham [1995] J. Physiol. 482:363-372). To explain the results of a rich set of experi
Biodegradable supermacroporous PHEMA cryogels were produced by combining two cross-linkers, poly(ethylene glycol) diacrylate and a newly developed disulfide water soluble crosslinker, N,N'-bis(methacryloyl)-L-cystine. The biodegradable PHEMA cryogels were prepared with gel fraction yields up to 70% and were characterized by highly interconnected pores of micrometer size and good mechanical stabili
Background. Although the topic of pain among older people has received increasing interest, little is still known about how pain is experienced or handled by those who no longer manage independently but depend on professionals for help with daily living. Developing pain management for older people requires such knowledge. Aim. To explore sense of self, sense of pain, daily living with pain, sense
The redshank (Tringa totanus) is declining throughout Europe and to implement efficient conservation measures, it is important to obtain information about the population genetic structure. The aim of the present study was two-fold. First, we analysed the genetic variation within and between populations in the Baltic region in southern Scandinavia. Evidence of genetic structure would suggest that d
This study investigates the role of political journalism in European Union (EU) constitution-making. It is asked whether and to what extent quality newspaper journalists act as an impartial mediator or as an active promoter of normative debates on European integration across national media spheres. The ratification period of the EU Constitutional Treaty (CT) (November 2004-June 2005) is analysed a
Selective supercritical fluid extraction (SFE) at 40 degrees C, 400 bar and 60 min was used to selectively remove bioavailable PCBs from a naturally contaminated limnic sediment. The extraction decreased the sediment concentrations of the nine studied PCBs by 54% (on average). Chironomid larvae were thereafter cultured in pre-extracted sediment as well as in untreated sediment to study the differe
Projected body frontal area is used when estimating the parasite drag of bird flight. We investigated the relationship between projected frontal area and body mass among passerine birds, and compared it with an equation based on waterfowl and raptors, which is used as default procedure in a widespread software package for flight performance calculations. The allometric equation based on waterfowl/
The spread of cancer cells to regional lymph nodes through the lymphatic system is the first step in the dissemination of breast cancer. In several human cancers including those of the breast and prostate, the expression of vascular endothelial growth factor C (VEGF-C) is associated with lymph node metastasis. Our study was undertaken to evaluate the effect of VEGF-C on metastasis of poorly invasi
Sixteen open-top chambers (diameter, 3.66 m) were established in a scrub oak habitat in central Florida where vegetation was removed in a planned burn prior to chamber installation. Eight control chambers have been continuously exposed to ambient air and eight have been continuously exposed to elevated CO2 at twice-ambient concentration (similar to700 ppm) for 5 years. Soil cores were collected fr
Impactor sampling and PIXE analysis constitute a good combination in detecting the influence of fugitive emission and ventilation air on ambient air quality. In total filter samples heavier natural particles mask the increase in mass due to the smaller industrial particles. Multielemental analysis of many samples is important in finding unknown sources and in evaluating the effect of all the sourc
The spin-forbidden reaction of Fe(CO)(4)+CO -> Fe(CO)(5) has been investigated with multiconfigurational quantum chemical methods (CASSCF/CASPT2). The structure of the minimum energy crossing point ( MECP) between the singlet and triplet energy surfaces as well as the equilibrium structures of Fe(CO)(5) ( a singlet state) and Fe(CO)(4) ( a triplet state) has been determined. The partition rational
The associations between educational level, preclinical carotid atherosclerosis and incident coronary events (CE), were investigated in a general population sample of 5399 Swedish middle-aged men and women without history of cardiovascular disease (CVD) over a median follow-up of 8.7 years. Presence of carotid plaque (focal intima-media thickness (IMT) >1.2 mm) was determined by B-mode ultrasound.
The inflammatory mediator leukotriene B(4) (LTB(4)) binds to and activates a G-protein-coupled receptor named BLT(1). We have previously produced two monoclonal antibodies, named 7B1 and 14F11, that bind specifically to this receptor. Using a HeLa cell line expressing human BLT(1), we find that both antibodies inhibit LTB(4)-induced calcium release, and activation of a MAP-kinase-sensitive lucifer
Background. Persistent pain is a common problem for older people. Knowledge about how nursing and paramedical staff perceive these people and what they do to relieve the pain seems scarce. Aim. To explore nursing and paramedical staff perceptions of older people in persistent pain and their day-to-day management of pain. Methods. Interviews in Swedish with 52 nursing auxiliaries, Registered Nurs
The Integral Dictionary is a comprehensive lexical network for French, English, German, Italian, and Spanish. It is based on componential semantics and lexical functions. The network structure superimposes two graphs. A first graph consists of a hierarchy of concepts divided into classes and themes where the words form the terminal nodes of the graph. A second graph links the words together using
