Ion and solvent dynamics in gel electrolytes based on ethylene oxide grafted acrylate polymers

Multinuclear pulsed field gradient NMR measurements and theological viscosity measurements were performed on three series of polymer gel electrolytes. The gels were based on a lithium salt electrolyte swollen into a copolymer matrix comprising an acrylate backbone and ethylene oxide side chains. In each series the side chains differed in length and number, but the acrylate-to-ethylene oxide ratio

Review of D. Kremendahl. Die Botschaft der Form. Zum Verhältnis von antiker Epistolographie und Rhetorik im Galaterbrief (Novum Testamentum et Orbis Antiquus, 46)

Denna avhandling tar upp frågan om det epistolografiska formuläret, genrefrågan, den retoriska dispositionen i Galaterbrevet samt sammanfattar på ett bra sätt resultaten. Bokens titel antyder redan huvudresultatet av undersökningen, nämligen att själva den yttre formen har större betydelse för budskapet än man vanligtvis tillmäter denna. Och här är det alltså fråga om den epistolografiska som man This dissertation handles the question of the rhetorical formula, the genre and the rhetorical disposition of Galatians. There is also an excellent summary with further perspectives. The title of the book already gives a glimpse of the main result, namely that the form has more bearing on the message than usually acknowledged. Here it is the question of the epistolographical form which often is tr

C-Med 100, a hot water extract of Uncaria tomentosa, prolongs lymphocyte survival in vivo.

Water extracts of the bark of Uncaria tomentosa, a vine indigenous to South America, has been used for generations as an "immuno modulator". To understand the basis of this immuno modulatory effect we fed mice in their drinking water with C-Med 100, which is a commercially available water extract from Uncaria tomentosa. We found a dose-dependent increase in spleen cell numbers in the supplemented

Band Crossings in 83Y Revisited

Gamma rays from the reaction Si-28(Ni-58, 3p)83Y at a beam energy of 195 MeV were recorded in recoil-gamma- and gamma-gamma-coincidence mode with the POLYTESSA array and the Daresbury recoil mass separator. The known rotational bands were extended up to probable spins 49/2+ and 45/2-; many new interconnecting dipole transitions and an additional cascade were established. The bands are interpreted

Anomalies on capture nets of Hydropsyche slossonae larvae (Trichoptera; Hydropsychidae) following a sublethal chronic exposure to cadmium

A laboratory study on the sublethal effects of cadmium (Cd) on the net-spinning process of the larvae of Hydropsyche slossonae was conducted in order to assess the potential of net anomalies as an indicator of chronic exposure to Cd. Two major anomalies with different frequency levels were identified after chronic exposure to 0.37, 1.2, 11.6, 21.4 and 43.3 μg l−1 of Cd. The first was a distortion

Darmin is a novel secreted protein expressed during endoderm development in Xenopus.

Endoderm development is an area of intense interest in developmental biology, but progress has been hampered by the lack of specific markers for differentiated endodermal cells. In an unbiased secretion cloning screen of Xenopus gastrula embryos we isolated a novel gene, designated Darmin. Darmin encodes a secreted protein of 56 kDa containing a peptidase M20 domain characteristic of the glutamate

Nitric oxide exposure diverts neural stem cell fate from neurogenesis towards astrogliogenesis

Regeneration of cells in the central nervous system is a process that might be affected during neurological disease and trauma. Because nitric oxide (NO) and its derivatives are powerful mediators in the inflammatory cascade, we have investigated the effects of pathophysiological concentrations of NO on neurogenesis, gliogenesis, and the expression of proneural genes in primary adult neural stem c

Sex differences in strategy and performance on computerized neuropsychological tests as related to gender identity and age at puberty

Neuropsychological sex differences have since long been under debate. Support for the relation between behavioral differences and biological variables like hormone influence is, however, emerging. Sixteen men and sixteen women, all university students, were tested with computerized neuropsychological tests (APT), the Bem Sexual Role Inventory, and asked about pubertal age. The results were in line

Structure, Evolution, and Expression of Proteins in the Male Reproductive Tract. Studies on Semenogelins, Beta-Microseminoprotein, and PC3-Secreted Microprotein.

Human semen has several important constituents, including the prostate secreted proteins beta-microseminoprotein (MSP), prostate-specific antigen (PSA) and prostatic acid phosphatase (PAP), and the seminal-vesicle-derived coagulum proteins semenogelin I (SEMG1) and semenogelin II (SEMG2). The research underlying this thesis explored the evolution, expression and structure of seminal plasma protein

Long-term manipulation of the microbes and microfauna of two subarctic heaths by addition of fungicide, bactericide, carbon and fertilizer

Nutrient availability is a major constraint to plant production and carbon storage in arctic ecosystems, but there are few studies coupling processes in the decomposer and microbial food web and the implications these processes have on the control of nutrient mineralization. We studied the relationship between microbial biomass and the abundance of microbivore and the role of grazing on nutrient t

A review of the production of ethanol from softwood

Ethanol produced from various lignocellulosic materials such as wood, agricultural and forest residues has the potential to be a valuable substitute for, or complement to, gasoline. One of the major resources in the Northern hemisphere is softwood. This paper reviews the current status of the technology for ethanol production from softwood, with focus on hemicellulose and cellulose hydrolysis, whi

Nitric oxide independent activation of guanylate cyclase by YC-1 causes erectile responses in the rat.

PURPOSE: Activation of soluble guanylate cyclase with a subsequent increase in intracellular levels of cyclic guanosine monophosphate is necessary for normal erection. In vascular tissue 3(5'-hydroxymethyl-2'-furyl-1-benzyl indazole (YC-1) (Abbott Laboratories, North Chicago, Illinois) has been shown to stimulate soluble guanylate cyclase independent of nitric oxide. We studied whether YC-1 modula

Extraction of plasmid DNA from Escherichia coli cell lysate in a thermoseparating aqueous two-phase system

The primary purification of a 6.1kilo base pair (kbp) plasmid from a desalted alkaline lysate has been accomplished by a thermoseparating aqueous two-phase system [(50% ethylene oxide-50% propylene oxide)-Dextran T 500]. The partitioning of the different nucleic acids (plasmid DNA, RNA, genomic DNA) in the thermoseparating aqueous two-phase system was followed both qualitatively by agarose gel ele

Effect of surface grafted polymers on the adsorption of different model proteins

Adsorption of a model protein to a surface with end-grafted polymers was studied by Monte Carlo simulations. In the model the effect on protein adsorption in the presence of end-grafted polymers was evaluated by calculating the change in free energy between an end-grafted surface and a surface without polymers. The change in free energy was calculated using statistical mechanical perturbation theo
