We develop an extended classical density-functional theory to describe clustering of imidazolium-based cations into linear chains, driven by π-π stacking. We find that the associating system displays a similar short-ranged structure to the completely dissociated fluid. We also construct a restricted primitive model for associating ionic species in an RTIL+solvent mixture. The double-layer formed i
Some of the objections to life-extension stem from a concern with overpopulation. I will show that whether or not the overpopulation threat is realistic, arguments from overpopulation cannot ethically demand halting the quest for, nor access to, life-extension. The reason for this is that we have a right to life, which entitles us not to have meaningful life denied to us against our will and which
The aim of the present study was to investigate whether virulent CagA positive Helicobacter pylori strains are those preferentially related to abdominal aortic aneurysm (AAA) rupture. Several microorganisms have been linked to aneurysm development. Chronic Chlamydophila pneumoniae infection has been suggested as a possible contributing factor for the development and expansion of AAA. Previous stud
How come a continent with thousands of companies only export one percent of its goods on the international market? Why are African companies not even competitive on local African markets? In July 2001, African leaders came up with an ambitious programme called The New Partnership for Africa’s Development (NEPAD). The programme has the objective of being a kind of Marshall Plan for Africa. It deals
First predictions for specific case of the particle-hole-core coupling model which takes advantage of symmetries of a triaxial rotor with gamma = 90 degrees are reviewed. Results of the model calculations point towards existence of stable chiral geometry in specific configurations involving high-j orbitals. Next, experimental information on doublet bands built on unique parity, pi(h)11/2(Vh)11/2 i
Cerebellar Purkinje cells can learn to respond to a conditioned stimulus with an adaptively timed pause in firing. This response was usually ascribed to long-term depression of parallel fiber to Purkinje cell synapses but has recently been shown to be due to a previously unknown form of learning involving an intrinsic cellular timing mechanism. Here, we investigate how these responses are elicited
The capability of wood-rotting fungi (WRF) to colonise contaminated soil is an important fungal characteristic in the development of WRF-based soil bioremediation, it is also important to have methods that monitor the presence of the WRF in the soil. In this lab-scale study, it was shown that it was possible to re-capture, localise and identify a brown-rot fungus, Antrodia vaillantii, after it has
In vitro studies were performed on lymphatics obtained from the groin in 19 patients undergoing vascular surgery. The lymphatics were mounted in tissue baths, and isometric contractions were induced by increasing concentrations of the thromboxane A2 (TXA2) mimetic U-46619. In comparison to K+ (124mM)-induced contraction, which were used as an internal standard, the response to U-46619 had an Emax
We give a simpler proof of the formula, due to J.-L. Lions, for the reproducing kernel of the space of harmonic functions on a domain Omegasubset ofR(n) whose boundary values belong to the Sobolev space H-s(partial derivativeOmega), and also obtain generalizations of this formula when instead of harmonic functions one considers functions annihilated by a given elliptic partial differential operato
Background: The neuronal ceroid lipofuscinoses (NCLs) are a group of inherited neurodegenerative disorders characterized by accumulation of autofluorescent material in many tissues, especially in neurons. Mutations in the CLN8 gene, encoding an endoplasmic reticulum ( ER) transmembrane protein of unknown function, underlie NCL phenotypes in humans and mice. The human phenotype is characterized by
Kunskapens värde visar sig i allt större utsträckning inom olika organisationer idag. Många företagsledare inser att för företaget relevant kunskap är en stor konkurrenskraft på den globala marknaden. Detta gör att många företag skaffar sig kunskapshanteringssystem för att bevara den kunskap som finns hos olika individer inom företaget. Utveckling och implementering av sådana system har visat sig
Laminins are widely distributed extracellular matrix proteins. Certain laminin isoforms are predominant in vascular basement membranes and may be critical in maintaining the stability of the mature vessel. On the other hand, formation of new vessels during angiogenesis requires degradation of the basement membrane, exposing the endothelial cells to other laminin isoforms in the surrounding extrace
Ion implantation modifies the surface properties of different materials. We have compared the biological properties of titanium implanted with nitrogen with those of pure titanium. Implants were inserted in the abdominal wall of rats. The implants with surrounding tissue were excised after 1 and 6 weeks, and embedded in epoxy resin. The bulk metal was removed electrochemically and the tissue cut f
1. We studied the resting metabolic rate (MR) from two great tit Parus major (Linnaeus) populations living in different winter regimes. Birds from the two different localities were exposed individually to +25 °C, 0 °C and −10 °C for the night in three consecutive sessions in random order. 2. Birds from Lund (Sweden) had a lower basal MR, as measured at thermoneutrality (+25 °C), than had birds f
A fundamental understanding of protein stability and the mechanism of denaturant action must ultimately rest on detailed knowledge about the structure, solvation, and energetics of the denatured state. Here, we use 17O and 2H magnetic relaxation dispersion (MRD) to study urea-induced denaturation of intestinal fatty acid-binding protein (I-FABP). MRD is among the few methods that can provide molec
Cysteine-rich secretory protein 3 (CRISP-3; also known as SGP28) was originally discovered in human neutrophilic granulocytes. We have recently developed a sensitive sandwich enzyme-linked immunosorbent assay for CRISP-3 and demonstrated the presence of CRISP-3 in exocrine secretions. To investigate the subcellular localization and mobilization of CRISP-3 in human neutrophils, we performed subcell
Human cysteine-rich secretory protein 3 (CRISP-3; also known as SGP28) belongs to a family of closely related proteins found in mammals and reptiles. Some mammalian CRISPs are known to be involved in the process of reproduction, whereas some of the CRISPs from reptiles are neurotoxin-like substances found in lizard saliva or snake venom. Human CRISP-3 is present in exocrine secretions and in secre
