Direct Site-Directed Photocoupling of Proteins onto Surfaces Coated with beta-Cyclodextrins

A method called Dock'n'Flash was developed to offer site-specific capture and direct UVA-induced photocoupling of recombinant proteins. The method involves the tagging of recombinant proteins with photoreactive p-benzoyl-L-phenylalanine (pBpa) by genetic engineering. The photoreactive pBpa tag is used for affinity capture of the recombinant protein by beta-cyclodextrin (beta-CD), which provides hy

Compact binaries, hypernovae, and GRBs

The collapse of a massive stellar core may lead to the production of a black hole surrounded by a torus of material. Such a system is a potential source for the so-called long gamma-ray bursts (GRBs). A torus will form around the black hole if the infalling material contains sufficient angular momentum. This however requires that the core of the massive star rotates extremely rapidly prior to coll

Dispersion and interaction of graphene oxide in amorphous and semi-crystalline nano-composites: a PALS study

The influence of dispersion and interaction of Graphene Oxide (GO) in semi-crystalline Polyhydroxy butyrate (PHB) and glassy amorphous Poly(tBP-oda) is explored by Positron Annihilation Lifetime Spectroscopy (PALS). The ortho-Positronium lifetimes which represent the main free volume hole size of both polymers are mainly affected by the large differences in internal stresses built up by the shrink

A Cereal-Based Evening Meal Rich in Indigestible Carbohydrates Increases Plasma Butyrate the Next Morning.

Epidemiological studies have shown an inverse relation between a whole grain consumption and risk of type-2 diabetes and cardiovascular disease. One tentative mechanism relates to colonic metabolism of indigestible carbohydrates. In a previous study, we reported a positive relation between colonic fermentation and improved glucose tolerance. This work can be seen as an extension of that study, foc

How Civilized Were the Victorians?

This article addresses the role of the civilizing process' in the historiography of the Victorian period. The author develops a critique of perspectives that deem the nineteenth century to be an era of discipline and self-restraint, arguing that these result from the hegemonic position of literary perspectives within Victorian Studies and their frequent reliance on Foucauldian-inspired techniques

Parameter influence on moisture induced eigen-stresses in timber

Moisture induced stress in timber is dependant on many factors. The driving force behind is the moisture variation in the surrounding air which causes induced stress due to restraint of hygro-expansion within timber elements (this can to some extent be seen analogous to thermally induced stress in steel). Today's computational power together with advanced constitutive models offers aaEuro-aEuro-va

Barrier-enforcing measures as treatment principle in allergic rhinitis: a systematic review

Background and objectives Barrier-enforcing measures have been suggested as treatment options for allergic rhinitis. This review identifies and describes the literature on the subject. Methods Relevant publications were searched for in the PubMed database (search entries: 'allergic rhinitis' and 'treatment'). The evaluation comprised condition (seasonal or perennial allergic rhinitis), type of int

The structure of star clusters in the outer halo of M31

We present a structural analysis of halo star clusters in M31 based on deep Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) imaging. The clusters in our sample span a range in galactocentric projected distance from 13 to 100 kpc and thus reside in rather remote environments. Ten of the clusters are classical globulars, whilst four are from the Huxor et al. population of extended, ol

Holocene climate and environmental change in north-eastern Kamchatka (Russian Far East), inferred from a multi-proxy study of lake sediments

A sediment record from a small lake in the north-eastern part of the Kamchatka Peninsula has been investigated in a multi-proxy study to gain knowledge of Holocene climatic and environmental change. Pollen, diatoms, chironomids and selected geochemical parameters were analysed and the sediment record was dated with radiocarbon. The study shows Holocene changes in the terrestrial vegetation as well

The weighted Weiss conjecture and reproducing kernel theses for generalized Hankel operators

The weighted Weiss conjecture states that the system theoretic property of weighted admissibility can be characterized by a resolvent growth condition. For positive weights, it is known that the conjecture is true if the system is governed by a normal operator; however, the conjecture fails if the system operator is the unilateral shift on the Hardy space (discrete time) or the right-shift semigro

Circannual variation in blood parasitism in a sub-Saharan migrant passerine bird, the garden warbler

Knowing the natural dynamics of pathogens in migratory birds is important, for example, to understand the factors that influence the transport of pathogens to and their transmission in new geographical areas, whereas the transmission of other pathogens might be restricted to a specific area. We studied haemosporidian blood parasites of the genera Plasmodium, Haemoproteus and Leucocytozoon in a mig

New age (ca. 2970 Ma), mantle source composition and geodynamic constraints on the Archean Fiskenaesset anorthosite complex, SW Greenland

The Archean Fiskenaesset Complex, SW Greenland, consists of an association of ca. 550-meter-thick layered anorthosite, leucogabbro, gabbro, and ultramafic rocks (peridotite, pyroxenite, dunite, hornblendite). The complex was intruded by tonalite, trondhjemite, and granodiorite (TTG) sheets (now orthogneisses) during thrusting that was followed by several phases of isoclinal folding. The trace elem

Institutional Objects, Reductionism and Theories of Persistence

Can institutional objects be identified with physical objects that have been ascribed status functions, as advocated by John Searle in The Construction of Social Reality (1995)? The paper argues that the prospects of this identification hinge on how objects persist – i.e. whether they endure, perdure or exdure through time. This important connection between reductive identification and mode of per

STrengthening the Reporting of OBservational studies in Epidemiology - Molecular Epidemiology (STROBE-ME): An extension of the STROBE statement.

SUMMARY POINTS: Advances in laboratory techniques have led to a rapidly increasing use of biomarkers in epidemiological studies. Biomarkers of internal dose, early biological change, susceptibility and clinical outcomes are used as proxies for investigating interactions between external and/or endogenous agents and body components or processes. The need for improved reporting of scientific researc

The Journey to Establish CGRP as a Migraine Target: A Retrospective View.

In this retrospective, Dr. Lars Edvinsson recounts early steps and milestones in our understanding of the neuropeptide calcitonin gene-related peptide (CGRP) in the trigeminovascular system and its role in migraine. The discovery of the presence and function of CGRP and other neuropeptides in the cerebral vasculature and its sensory innervation is described. He relates the seminal finding that CGR

Optimal management of renal artery fibromuscular dysplasia.

Fibromuscular dysplasia (FMD) is a nonatherosclerotic, noninflammatory angiopathy of unknown cause affecting medium-sized (most commonly renal) arteries and causing renovascular hypertension. The most common medial multifocal type of FMD (with the "string of beads" appearance) is more than four times more prevalent in females than in males. FMD accounts for up to 10% of cases of renovascular hyper

Body Size, Skills, and Income: Evidence From 150,000 Teenage Siblings

We provide new evidence on the long-run labor market penalty of teenage overweight and obesity using unique and large-scale data on 150,000 male siblings from the Swedish military enlistment. Our empirical analysis provides four important results. First, we provide the first evidence of a large adult male labor market penalty for being overweight or obese as a teenager. Second, we replicate this r

Hemodynamic causes of exercise intolerance in Fontan patients.

Exercise intolerance is frequent among Fontan patients and an important determinant for quality of life. This study investigated the hemodynamic causes of impaired exercise capacity in Fontan patients with particular focus on the influence of stroke volume index (SVI) and heart rate (HR).
