Active and separate secretion of fiber and penton base during the early phase of Ad2 or Ad5 infection

Fiber and penton base overproduced in adenovirus (Ad) infected cells can be secreted prior to progeny release and thereby regulate progeny spread. We aimed to investigate the mechanisms of fiber and penton base secretion in Ad2- or Ad5-infected A549 cells. Our flow cytometry analyses detected abundant surface fiber molecules, but little penton base molecules at 12 h post infection. Immunogold stai

Arsenic exposure from drinking water is associated with decreased gene expression and increased DNA methylation in peripheral blood

Background Exposure to inorganic arsenic increases the risk of cancer and non-malignant diseases. Inefficient arsenic metabolism is a marker for susceptibility to arsenic toxicity. Arsenic may alter gene expression, possibly by altering DNA methylation. Objectives To elucidate the associations between arsenic exposure, gene expression, and DNA methylation in peripheral blood, and the modifying eff

Gastric bypass in the pig increases GIP levels and decreases active GLP-1 levels

Gastric bypass surgery results in remission of type 2 diabetes in the majority of patients. The incretin hormones glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) have been implicated in the observed remission. Most knowledge so far has been generated in obese subjects. To isolate the surgical effects of gastric bypass on metabolism and hormone responses from

Thomas Piketty and the rate of time preference

Using a standard model in which the individual consumption path is computed solving an optimal control problem, we investigate central claims of Piketty (2014). Rather than r > g (confirmed in the data) r−ρ>g – with ρ being the rate of time preference – matters. If this condition holds and the elasticity of substitution in the production function is larger than one, the capital share converges to

Hydrodynamic difference between inline and batch operation of a rotor-stator mixer head - A CFD approach

Rotor-stator mixers (RSMs) can be operated in either batch or inline mode. When operating a rotor-stator geometry in batch mode, it typically experiences an order of magnitude higher volumetric flow through the stator than in inline mode. This is expected to cause differences in the flow and turbulence in the rotor-stator region. This study uses computational fluid dynamics (CFD) to study the hydr

“You don’t have to say straight out …” : Directed Impression Management at Victim–Offender Mediation Pre-meetings

Based on a study of two mediation centers in Sweden, this research shows how mediators encourage victim and offender impression management, regarding looks, attitudes, and speech. It shows how they supervise the emotion work of participants, preparing them for mediation encounters. The author investigates how mediators try to create a “balanced” interaction (e.g., preventing expressed prejudices o

Polarity and growth directions in Sn-seeded GaSb nanowires

We here investigate the growth mechanism of Sn-seeded GaSb nanowires and demonstrate how the seed particle and its dynamics at the growth interface of the nanowire determine the polarity, as well as the formation of structural defects. We use aberration-corrected scanning transmission electron microscopy imaging methodologies to study the interrelationship between the structural properties, i.e. p

Vectorial Hankel operators, Carleson embeddings, and notions of BMOA

Let (Formula presented.) denote the space of (Formula presented.)-valued analytic functions (Formula presented.) for which the Hankel operator (Formula presented.) is (Formula presented.)-bounded. Obtaining concrete characterizations of (Formula presented.) has proven to be notoriously hard. Let (Formula presented.) denote fractional differentiation. Motivated originally by control theory, we char

Tyrosine 842 in the activation loop is required for full transformation by the oncogenic mutant FLT3-ITD

The type III receptor tyrosine kinase FLT3 is frequently mutated in acute myeloid leukemia. Oncogenic FLT3 mutants display constitutive activity leading to aberrant cell proliferation and survival. Phosphorylation on several critical tyrosine residues is known to be essential for FLT3 signaling. Among these tyrosine residues, Y842 is located in the so-called activation loop. The position of this t

A healthier US diet could reduce greenhouse gas emissions from both the food and health care systems

The standard US diet contributes to greenhouse gas emissions (GHGE) from both the food system, and from the health system through its contribution to non-communicable diseases. To estimate the potential for diet change to reduce GHGE and improve public health, we analyzed the effect of adopting healthier model diets in the USA on the risk of disease, health care costs, and GHGE. We found that adop

On Locating Value in Making Moral Progress

The endeavour to locate value in moral progress faces various substantive as well as more formal challenges. This paper focuses on challenges of the latter kind. After some preliminaries, Section 3 introduces two general kinds of “evaluative moral progress-claims”, and outlines a possible novel analysis of a (quasi) descriptive notion of moral progress. While Section 4 discusses certain logical fe

Searching for a middle ground : anthropologists and the debate on the universalism and the cultural relativism of human rights

In the anthropological debate on human rights a new theoretical approach, a search for a middle ground, has been attempted to solve the dilemma of universalism versus cultural relativism. In the human rights discussion in general, and in the anthropological debate in particular, the dichotomy of universalism/relativism is seen as one major obstacle to the implementation. This article takes a criti

Genetic and regulatory mechanism of susceptibility to high-hyperdiploid acute lymphoblastic leukaemia at 10p21.2

Despite high-hyperdiploid acute lymphoblastic leukaemia (HD-ALL) being the most common subgroup of paediatric ALL, its aetiology remains unknown. Genome-wide association studies have demonstrated association at 10q21.2. Here, we sought to determine how this region influences HD-ALL risk. We impute genotypes across the locus, finding the single nucleotide polymorphism rs7090445 highly associated wi

Search for dark matter at colliders

Among the numerous proposals to explain the nature of dark matter, there is the weakly interacting massive particle (WIMP) scenario, which is based on a simple assumption that dark matter was in thermal equilibrium in the early hot Universe, and its particles have mass and interactions not too different from the massive particles in the standard model. In this Progress Article we overview the infe

Sequential Proton-Coupled Electron Transfer Mediates Excited-State Deactivation of a Eumelanin Building Block

Skin photoprotection is commonly believed to rely on the photochemistry of 5,6-dihydroxyindole (DHI)- and 5,6-dihydroxyindole-2-carboxylic acid (DHICA)-based eumelanin building blocks. Attempts to elucidate the underlying excited-state relaxation mechanisms have been partly unsuccessful due to the marked instability to oxidation. We report a study of the excited-state deactivation of DHI using ste

Ultrafast Time-Resolved X-ray Absorption Spectroscopy of Ferrioxalate Photolysis with a Laser Plasma X-ray Source and Microcalorimeter Array

The detailed pathways of photoactivity on ultrafast time scales are a topic of contemporary interest. Using a tabletop apparatus based on a laser plasma X-ray source and an array of cryogenic microcalorimeter X-ray detectors, we measured a transient X-ray absorption spectrum during the ferrioxalate photoreduction reaction. With these high-efficiency detectors, we observe the Fe K edge move to lowe

Targeted Proteomics Approach for Precision Plant Breeding

Selected reaction monitoring (SRM) is a targeted mass spectrometry technique that enables precise quantitation of hundreds of peptides in a single run. This technique provides new opportunities for multiplexed protein biomarker measurements. For precision plant breeding, DNA-based markers have been used extensively, but the potential of protein biomarkers has not been exploited. In this work, we d
