Reorganization of perylene bisimide J-aggregates: from delocalized collective to localized individual excitations.

Water-induced reorganization of individual one-dimensional J-aggregates of perylene bisimide (PBI) dyes was observed by fluorescence microscopy. Fluorescence spectra and decay kinetics of individual J-aggregates immobilized on glass surfaces were measured under a dry nitrogen atmosphere and under humid conditions. The fluorescence properties of PBI J-aggregates arisen from collective excitons unde

Human3.6M: Large Scale Datasets and Predictive Methods for 3D Human Sensing in Natural Environments.

We introduce a new dataset, Human3.6M, of 3.6 Million 3D Human poses, acquired by recording the performance of 11 subjects, under 4 different viewpoints, for training realistic human sensing systems and for evaluating the next generation of human pose estimation models. Besides increasing the size the current state of the art datasets by several orders of magnitude, we aim to complement such datas

Variability in the precore and core promoter region of the hepatitis B virus genome.

There is increasing evidence that hepatitis B virus (HBV) infections with different genotypes and subgenotypes differ in response to treatment and long-term prognosis. The differences emerge from variability within the genomes that leads to structural deviations at the pregenomic level and to changes at the translational level. Naturally occurring HBV strains covering the four major genotypes A-D

A study of dialogic expansion and contraction in spoken discourse using corpus and experimental techniques

This study examines the dialogic functions of EXPANSION and CONTRACTION of first-person epistemic and evidential Complement-Taking Predicate (CTP) constructions, such as I think COMPLEMENT, I suppose COMPLEMENT and I know COMPLEMENT, in spoken discourse. It combines corpus and experimental methods (i) to investigate whether CTP constructions are used to open up the dialogic space for new ideas or

Preparation of a portable point-of-care in vitro diagnostic system, for quantification of canine C-reactive protein, based on a magnetic two-site immunoassay.

In this study, characterization of the binding kinetics and optimization of a magnetic permeability based point-of-care (POC) immunoassay system for quantification of canine C-reactive protein (cCRP) is described. The reagent is based on a two-site heterogeneous immunoassay system utilizing conjugated superparamagnetic nanoparticles (SPION) and silica particles, both particles carrying covalently

Probiotic therapy to men with incipient arteriosclerosis initiates increased bacterial diversity in colon: A randomized controlled trial.

OBJECTIVE: This study aimed to clarify the microbial change in the intestinal microbiota in patients, with cardiovascular disease, consuming a drink with high numbers of live Lactobacillus plantarum. METHODS: Sixteen males, with atherosclerotic plaque on the carotid wall, were randomly selected from a larger cohort and included in this double blind, placebo controlled study. Colonic biopsies, take

Cardiac regeneration in vivo: Mending the heart from within?

A growing body of evidence has shown that the heart is not terminally differentiated but continues to renew its cardiomyocytes even after the neonatal period. This new view of the heart increases hope for changing the strategy for treating cardiac injuries toward regenerative approaches. However, the magnitude and clinical significance of this process in homeostasis and disease and the underlying

Gene therapy of focal-onset epilepsy by adeno-associated virus vector-mediated overexpression of neuropeptide Y

P>Adeno-associated virus (AAV)-mediated neuropeptide Y (NPY) overexpression in areas of seizure onset or generalization may be effective for the treatment of pharmacoresistant seizures in focal onset epilepsy. NPY overexpression mediates anticonvulsant activity in various seizures models and antiepileptogenic effects in kindling. Side effects are limited thus suggesting that this therapeutic appro

Midkine is part of the antibacterial activity released at the surface of differentiated bronchial epithelial cells

To resist infections, robust defense mechanisms of the airways are essential. Retinoic acid promotes differentiation and maintains the phenotypic characteristics of bronchial epithelium. In addition, it induces the expression of the antibacterial growth factor midkine (MK). In the present study, we explored the expression and antibacterial activity of MK in an airway context. MK was detected in br

Photo-electrochemical communication between cyanobacteria (Leptolyngbia sp.) and osmium redox polymer modified electrodes.

Photosynthetic microbial fuel cells (PMFCs) are an emerging technology for renewable solar energy conversion. Major efforts have been made to explore the electrogenic activity of cyanobacteria, mostly using practically unsustainable reagents. Here we report on photocurrent generation (≈8.64 μA cm(-2)) from cyanobacteria immobilized on electrodes modified with an efficient electron mediator, an Os(

Influence of soot aggregate structure on particle sizing using laser-induced incandescence: importance of bridging between primary particles

Soot aggregates formed in combustion processes are often described as clusters of carbonaceous particles in random fractal structures. For theoretical studies of the physical properties of such aggregates, they have often been modelled as spherical primary particles in point contact. However, transmission electron microscopy (TEM) images show that the primary particles are more connected than in a

Galectin-3 deficiency protects pancreatic islet cells from cytokine-triggered apoptosis in vitro

Beta cell apoptosis is a hallmark of diabetes. Since we have previously shown that galectin-3 deficient (LGALS3/) mice are relatively resistant to diabetes induction, the aim of this study was to examine whether beta cell apoptosis depends on the presence of galectin-3 and to delineate the underlying mechanism. Deficiency of galectin-3, either hereditary or induced through application of chemical

Scaling-up the acid-enhanced electrokinetic remediation of a real contaminated soil

Although there is a lot of experimental work published about the use of Electrokinetic Remediation for the removal of toxic metals from soils, very few have reported results for different scales. Scaling- up is a difficult task, since the behavior of each metal is different and is also site-specific. In this paper we present a convenient parameter for the comparison of the energy requirements at d
