Density Functional Study of Surface Forces in Athermal Polymer Solutions with Addititve Hard Sphere Interactions. Solvent Effects, Capillary Condensation and Capillary-Induced Surface Transitions.

A density functional theory for polymer solutions is generalized to cases where the monomers have a different diameter to the solvent. An appropriate free energy functional is obtained by integration of the generalized Flory equation of state for such systems. This functional predicts that entropic demixing may occur in polymer solutions in which the solvent particles are smaller than the monomers

Powerful cyclosporin inhibition of calcium-induced permeability transition in brain mitochondria.

The mitochondrial permeability transition (mPT) is considered to be an important mediator of apoptosis and necrosis, and is specifically blocked by cyclosporin A (CsA). CsA has been shown to exert a potent neuroprotective action in vivo when allowed to cross the blood–brain barrier in various animal models of acute neurological insults and neurodegenerative disease. The neuroprotective effect of C

HAMLET kills tumor cells by apoptosis: Structure, cellular mechanisms, and therapy

New cancer treatments should aim to destroy tumor cells without disturbing normal tissue. HAMLET (human a-lactalbumin made lethal to tumor cells) offers a new molecular approach to solving this problem, because it induces apoptosis in tumor cells but leaves normal differentiated cells unaffected. After partial unfolding and binding to oleic acid, α-lactalbumin forms the HAMLET complex, which enter

Who speaks? And who listens? The relationship between planners and women’s participation in local planning in a multi-cultural urban environment

In recent decades, the dominant planning discourse has undergone a great change from a previous top-down approach towards collaborative and communicative planning. Instead of merely planning for the people in a technocratic and positivist approach, planners are increasingly expected to pay attention to the voices of the citizens. However, within this new participatory approach there is a growing p

Paralysis of nematodes: shifts in the transcriptome of the nematode-trapping fungus Monacrosporium haptotylum during infection of Caenorhabditis elegans

The transcriptional response in the parasitic fungus Monacrosporium haptotylum and its nematode host Caenorhabditis elegans were analyzed during infection using cDNA microarrays. The array contained 2,684 fungal and 372 worm gene reporters. Dramatic shifts occurred in the transcriptome of M. haptotylum during the different stages of the infection. An initial transcriptional response was recorded a

Guidelines for education and training of medical physicists in radiotherapy - Recommendations from an ESTRO/EFOMP working group

Purpose: To provide a guideline curriculum covering theoretical and practical aspects of education and training for medical physicists in radiotherapy within Europe. Material and methods: Guidelines have been developed for the specialist theoretical knowledge and practical experience required to practice as a medical physicist in radiotherapy. It is assumed that the typical entrant into training w

Personalised nutrition : status and perspectives

Personalised, genotype-based nutrition is a concept that links genotyping with specific nutritional advice in order to improve the prevention of nutrition-associated, chronic diseases. This review describes the current scientific basis of the concept and discusses its problems. There is convincing evidence that variant genes may indeed determine the biological response to nutrients. The effects of

Non-linear regional relationships between climate extremes and annual mean temperatures in model projections for 1961-2099 over Europe

A simple method is tested for scaling climate-extreme results from high resolution regional climate models (RCMs) to time-periods and emission scenarios for which the RCMs have not been run. The 30 yr mean relationships between indicators of extremes (IoEs) and annual mean daily maximum temperature (T-xa) are investigated. Such relationships from the UK Met Office Hadley Centre RCM HadRM3P, along

Census of binaries - The big picture

Gaia will observe huge numbers of binaries with a large range of periods. The present contribution tries to present some estimates of the expected number of detections and/or orbit determinations, based on simplified but large-scale simulations. The simulations have to model both a Galaxy with binaries, the instrument and observations, and the reduction programs. As in previous studies, there are

Moisture diffusivities evaluated at high moisture levels from a series of water absorption tests

This paper presents measured moisture diffusivities for sedimentary calcareous sandstone, lime silica bricks, bricks, and autoclaved, aerated concrete. The moisture diffusivities were calculated from the relation between the water sorption coefficients and the initial water content in the specimen before testing. The method used is based on Boltzmann transformation. The relation between the water

Islet constitutive nitric oxide synthase and glucose regulation of insulin release in mice

We have studied, by a combined in vitro and in vivo approach, the relation between the inhibitory action of N(G)-nitro-l-arginine methyl ester (L-NAME), a selective inhibitor of nitric oxide synthase (NOS), on the activity of islet constitutive NOS (cNOS) and glucose regulation of islet hormone release in mice. The cNOS activity in islets incubated in vitro at 20 mM glucose was not appreciably aff

Compact fiber-optic fluorosensor using high-power continuous-wave violet diode laser

In this work a compact fluorosensor has been built for point-monitoring and imaging applications. The instrument has been applied in fluorescence studies on green vegetation and on malignant tissue. The instrument is based on a violet diode laser, an integrated spectrometer and optical fibers for light delivery and collection of the fluorescence signal. This combination makes the system very compa

Generation of molecular recognition sites in electrospun polymer nanofibers via molecular imprinting

A simple method for the formation of molecular recognition sites in polymer nanofibers was developed. Electrospun nanofibers were prepared from a Solution mixture of poly(ethylene terephthalate) (PET) and polyallylamine in the presence of a template molecule, 2,4-dichlorophenoxyacetic acid (2,4-D). The polyamine was used to provide functional groups that interact with the template during the elect

Conodont biostratigraphy and sedimentary history in the upper Tremadoc at Uuga, Cape Pakri, NW Estonia

The upper Tremadocian boundary beds at Cape Pakri, NW Estonia, consist of an extremely friable glauconitic sandstone, which presents a challenge to detailed biostratigraphy. A combination of sedimentological and biostratigraphical criteria has served to clarify the tempo and mode of the processes that formed the sandstone and explain its relationships to strata immediately below and above it. Apat

Is there a relationship between fibromyalgia syndrome and work conditions?

Objectives: This Study examines the initial course of the fibronlyalgia syndrome [FMS] and the influence of physical and psychosocial work-place factors on developing FMS. Methods: Patients with FMS were recruited to participate in a structured interview about pain and physical and psychosocial load. In addition, they participated in a clinical examination. Physical load in occupational life was a
