The partial phase diagram of D2O/n-octyl-beta-D-alkyl-glucoside(C(8)G(1))/n-octane has been determined at T = 25 degrees C. The diagram contains a funnel-shaped micellar phase originating from the water corner of the phase diagram D2O/C(8)G(1) with the stern forming a narrow three-phase region, in which the three phases in equilibrium are two microemulsions of similar composition and an excess oil
Na+/H+ exchangers are ubiquitous in mammalian cells, carrying out key functions, such as cell volume defense, acid-base homeostasis, and regulation of the cytoskeleton. We used two screening technologies (FLIPR and microphysiometry) to characterize the signal transduction pathway used by the bradykinin beta(2) receptor to activate Na+/H+ exchange in two cell lines, KNRK and CHO. In both cell types
The isothermal pseudo-ternary-phase diagram was determined at 25 degreesC for systems composed of lecithin, water, and, as oil, either isooctane or decane. This was accomplished by a combination of polarizing microscopy, small-angle X-ray scattering, and NMR techniques. The lecithin-rich region of the phase diagram is dominated by a lamellar liquid-crystalline phase (L-alpha). For lecithin content
We review and discuss the importance of correlational selection (selection for optimal character combinations) in natural populations. If two or more traits subject to multivariate selection are heritable, correlational selection builds favourable genetic correlations through the formation of linkage disequilibrium at underlying loci governing the traits. However, linkage disequilibria built up by
Methods for planning and control of the flow of material in the manufacturing enterprise are more or less appropriate to use in a specific situation, mainly depending on the existing planning environment. How well they contribute to an effective material flow is also depending on how they are applied. This paper examines which material planning methods companies are using, to what extent these met
Two extreme groups of healthy male undergraduate students, either highly (n=12) or low creative (n=12), were pre-selected from a larger cohort (N=60) by way of the Creative functioning test (Smith & Carlsson, 1990). The two groups underwent measurements of regional cerebral blood-flow (rCBF). rCBF was measured during rest and during three verbal tasks (random order): Automatic speech (Auto), w
In a very few years, the video capsule for small bowel enteroscopy has gained widespread clinical acceptance. It is readily ingested, disposable, and allows for a complete, low-invasive endoscopic examination of the entire mucosa of the small bowel. It is a patient-friendly method and a first-line procedure in the difficult evaluation of obscure gastrointestinal bleeding. It has the highest proven
Gene amplification is one of the mechanisms for oncogene activation in solid tumors. The size of the amplified regions may vary considerably among individual tumors, and more than one gene may be affected within the same amplicon. The main objective in analyzing genomic amplifications has therefore been to map the shortest region involved and to identify genes with increased expression as a result
A formula of Walczak is applied to two situations in differential geometry. Holomorphic distributions on Kahler manifolds are studied, and it is shown how the formula simplifies to a Bochner type formula, which is particularly useful in the study of integrable distributions. Then the Walczak formula is applied in the context of harmonic morphisms, where it provides a means of investigating the ver
Some consequences of chaos in the nucleus are discussed. The decay-out from superdeformed band occurs in a region where normal-deformed states may be chaotic, and it is shown how the distribution of decay-out matrix elements may reveal the degree of chaos. The decay-out is mediated by doorway states that are not resolved in the A=190 region, but experimentally seen in 59Cu. A model for the decay-o
Synaptogenesis, the formation of functional synapses, is a crucial step for the development of the central nervous system. Among the genes involved in this process are cell adhesion molecules, such as protocadherins and neuroligins, which are essential factors for the identification of the appropriate partner cell and the formation of synapses. In this work, we studied the expression and the genet
We start by providing an evolutionary scenario for the emergence of semantics. It is argued that the evolution of anticipatory cognition and theory of mind in the hominids opened up for cooperation about future goals. This cooperation requires symbolic communication. The meanings of the symbols are established via a "meeting of minds." The concepts in the minds of communicating individuals are mod
It is now increasingly recognized that aviation is an important driver of individual and global mobility. Growth in mobility is not evenly distributed, however: recent studies indicate that a relatively small, highly mobile part of society may account for a large share of the total distances travelled. In reviewing one of the processes that may lead to growth in individual aeromobility, the paper
Cardiopulmonary diseases are major causes of death worldwide, but currently recommended strategies for diagnosis and prevention may be outdated because of recent changes in risk factor patterns. The Swedish CArdioPulmonarybioImage Study (SCAPIS) combines the use of new imaging technologies, advances in large-scale 'omics' and epidemiological analyses to extensively characterize a Swedish cohort of
One of the outstanding challenges for evolutionary biologists is to understand how developmental plasticity can influence the evolutionary process. Developmental plasticity frequently involves parental effects, which might enable adaptive and context-dependent transgenerational transmission of phenotypic strategies. However, parent-offspring conflict will frequently result in parental effects that
