The HER2-Encoded miR-4728-3p Regulates ESR1 through a Non-Canonical Internal Seed Interaction.

Since the early 1980s remarkable progress has been made in understanding the role of the HER2 locus in carcinogenesis, but many details of its regulatory network are still elusive. We recently reported the finding of 367 new human microRNA (miRNA) genes of which one, mir-4728, is encoded in an intron of the HER2 gene. Here, we confirm that the HER2 oncogene is a bi-functional locus encoding the me

Separating the wheat from the chaff - a strategy to utilize plant genetic resources from ex situ genebanks

The need for higher yielding and better-adapted crop plants for feeding the world's rapidly growing population has raised the question of how to systematically utilize large genebank collections with their wide range of largely untouched genetic diversity. Phenotypic data that has been recorded for decades during various rounds of seed multiplication provides a rich source of information. Their us

The ALICE muon spetrometer and related physics

ALICE is the LHC experiment dedicated to the study of heavy-ion collisions at extreme energy density where formation of the quark–gluon plasma is expected. Among the different observables, open heavy flavors and heavy quarkonia states are especially relevant. Indeed they will be copiously produced and they will provide sensitive information on the collision. In this paper, the ALICE muon spectrome

Resonance Raman and FTIR spectra of Mg-porphyrazines

Resonance Raman spectra (RRS) of Mg-tetraazaporphyrin (1) and Mg-tetraazaoctaphenylporphyrin (2) in solid crystal powder at ambient temperature and different excitation wavelengths were recorded and analyzed. FTIR spectra of 1 and 2 in solid crystal powder were also measured. On the basis of DFT quantum-chemical calculations the frequencies, maximum amplitude changes for internal coordinates, and

Atom-solid binding energy shifts for K 2p and Rb 3d sublevels

Binding energy shifts between free and solid state atoms for K 2p and Rb 3d photolines have been determined by measuring the vapor and solid state spectra simultaneously in similar experimental conditions applying synchrotron radiation excited photoelectron spectroscopy. This method has the important benefit that the work function is not needed to correct for different reference energy levels, the

A 9-centimorgan interval of chromosome 10 controls the T cell-dependent psoriasiform skin disease and arthritis in a murine psoriasis model

Psoriasis is a complex genetic disease of unresolved pathogenesis with both heritable and environmental factors contributing to onset and severity. In addition to a disfiguring skin inflammation, approximately 10-40% of psoriasis patients suffer from destructive joint involvement. Previously, we reported that the CD18 hypomorphic PL/J mouse carrying a mutation resulting in reduced expression of th

Finite element study of growth stress formation in wood and related distortion of sawn timber

Lack of straightness in timber is the most frequent complaint regarding solid (and laminated) timber products worldwide. Nowadays, customers demand higher quality in the shape stability of wood products than they did earlier. The final distortion of timber boards is mostly caused by moisture-related stresses in wood (drying distortions) and growth-related stresses (distortions appearing when logs

Ca2Pd3Ge, a new fully ordered ternary Laves phase structure

The title compound, Ca2Pd3Ge, was prepared as a part of a systematic investigation of the Ca-Pd-Ge ternary phase diagram. The structure was determined and refined from single-crystal X-ray diffraction data. It is a new fully ordered ternary Laves phase with the space group R-3m, Z=3, a=5.6191 (5) angstrom, c=12.1674 (7) angstrom. wR(2)=0.054 (all data) and is isostructural to Mg2Ni3Si (Noreus et a

Market and brand-oriented schools of positioning

Purpose – The purpose of this paper is to revise the concept of positioning to differentiate between fundamental approaches to it and chart a scheme of schools of positioning. Design/methodology/approach – An extensive literature review traces the roots and evolution of the concept. Two approaches to positioning are explored and related to the paradigms of market and brand orientation. Based on c

The physico-chemical properties of dietary fibre determine metabolic responses, short-chain Fatty Acid profiles and gut microbiota composition in rats fed low- and high-fat diets.

The aim of this study was to investigate how physico-chemical properties of two dietary fibres, guar gum and pectin, affected weight gain, adiposity, lipid metabolism, short-chain fatty acid (SCFA) profiles and the gut microbiota in male Wistar rats fed either low- or high-fat diets for three weeks. Both pectin and guar gum reduced weight gain, adiposity, liver fat and blood glucose levels in rats

Exocytosis in Type 2 Diabetes- Functional and genetic studies of hormone secretion

Popular Abstract in Swedish Typ 2 Diabetes (T2D) räknas som en folksjukdom i Sverige vilket innebär att den är så vanlig att minst 4 % av befolkningen är drabbad. Förekomsten av diabetes ökar lavinartat över hela världen och man beräknar att så många som 300 miljoner människor har diabetes idag. Socker är en livsviktig energikälla, men lagom är bäst Socker i mat förs ut till blodet och används soType 2 Diabetes (T2D) is characterized by dysregulated beta-and alpha-cell hormone secretion leading to elevated blood glucose levels. Several proteins are crucial in maintaining exocytosis of the hormone-containing granules such as Syntaxin1A (Stx1A), SNAP25, Munc-18 (Stxbp1) and the family of Synaptotagmins (Syts). The aim of this thesis has been to investigate functional and genetic events that

Bi-spectral beam extraction in combination with a focusing feeder

Bi-spectral beam extraction combines neutrons from two different kinds of moderators into one beamline, expanding the spectral range and thereby the utilization of an instrument. This idea can be realized by a mirror that reflects long wavelength neutrons from an off-axis colder moderator into a neutron guide aligned with another moderator emitting neutrons with shorter wavelengths which will be t

Trichoderma viride cellulase induces resistance to the antibiotic pore-forming peptide alamethicin associated with changes in the plasma membrane lipid composition of tobacco BY-2 cells.

Alamethicin is a membrane-active peptide isolated from the beneficial root-colonising fungus Trichoderma viride. This peptide can insert into membranes to form voltage-dependent pores. We have previously shown that alamethicin efficiently permeabilises the plasma membrane, mitochondria and plastids of cultured plant cells. In the present investigation, tobacco cells (Nicotiana tabacum L. cv Bright

Exciton dynamics in alternating polyfluorene/fullerene blends

Exciton dynamics in alternating copolymer/fullerene solar cell blends have been investigated using femtosecond transient absorption spectroscopy. The acceptor concentrations have been varied over a wide range. Experimental data, kinetic modeling and simulations, all indicate that the efficiency of exciton conversion to charges is 100% even at acceptor concentrations as low as 20 wt%. The reported

Dynamical Response of the Tropical Pacific Ocean to Solar Forcing During the Early Holocene

We present a high-resolution magnesium/calcium proxy record of Holocene sea surface temperature (SST) from off the west coast of Baja California Sur, Mexico, a region where interannual SST variability is dominated today by the influence of the El Nino-Southern Oscillation (ENSO). Temperatures were lowest during the early to middle Holocene, consistent with documented eastern equatorial Pacific coo

Biodiversity and the landscape ecology of agri-environment schemes

Loss of biodiversity in European farmland has been attributed to agricultural intensification and the resulting loss of ecological heterogeneity. To alleviate the effect of agricultural intensification, farmers are compensated via agri-environment schemes for carrying out farming in ways to preserve and restore biodiversity. However, the effectiveness of these schemes has been questioned and evalu
