Overexpression of Aurora-A promotes laryngeal cancer progression by enhancing invasive ability and chromosomal instability

The purpose of the study was to investigate the expression of Aurora-A in human laryngeal squamous cell carcinoma (LSCC) and to explore the effects of Aurora-A silencing on invasion and chromosomal instability in laryngeal cancer HEp-2 cells. The expression of Aurora-A mRNA and protein were studied using reverse transcription-PCR and Western blot in LSCC tissues and corresponding normal epithelium

A comparative study of nursing staff, care recipients and their relatives’ perceptions of quality of older people care

Background. Comparisons of different stakeholders' ratings of the quality of older people care can help to drive quality improvement. Aim. The aim was to compare staff, older care recipients' and their relatives' quality of care ratings. Design. Cross-sectional questionnaire surveys in 2003 and 2004, using a repeated measures design on an organizational level. Methods. Nursing staff, care recip

Quality of life, physical function and MRI T2*in elderly low-risk MDS patients treated to a haemoglobin level of >= 120 g/L with darbepoetin alfa +/- filgrastim or erythrocyte transfusions

Objective: Anaemia in low-risk MDS is associated with reduced quality of life (QoL). Response to treatment with erythropoietin (EPO) + G-CSF is associated with improved QoL, but whether transfusion therapy with higher haemoglobin (Hb) target levels has similar effects is unknown. The objective for this prospective phase II Nordic multicentre trial was to assess QoL, response rate and physical func

Banning homosexual propaganda. Belonging and visibility in contemporary Russian media

This article investigates Russian mainstream media’s coverage of the 2013 legislation banning “propaganda for non-traditional sexuality”. Inspired by theories on belonging, media and visibility, it reconstructs a dominant narrative representing non-heterosexuals as threatening the future survival of the nation, as imposing the sex-radical norms of a minority onto the majority, or as connected to a

Northern fowl mite (Ornithonyssus sylviarum) in Sweden

Haematophagous mites were collected from the vent region and plumage of chickens in six hobby flocks of ornamental breeds in Sweden, one of which included turkeys. Soiled vent skin and feathers, dermatitis, hyperkeratosis, skin necroses and ulcers were observed in 12 necropsied birds from two of the flocks. The mites were identified as the northern fowl mite Ornithonyssus sylviarum (Mesostigmata:

Role of Gα(olf) in Familial and Sporadic Adult-Onset Primary Dystonia.

The vast majority of patients with primary dystonia are adults with focal or segmental distribution of involuntary movements. Although approximately 10% of probands have at least one first- or second-degree relative with dystonia, large families suited for linkage analysis are exceptional. After excluding mutations in known primary dystonia genes (TOR1A, THAP1, and CIZ1), whole-exome sequencing id

Low energy spin wave excitations in amplitude modulated magnetic structure of PrNi2Si2

Inelastic neutron scattering (INS) experiments and random phase approximation calculations have been used to investigate the low energy spin wave excitations in PrNi2Si2. The modulated magnitude of the ordered magnetic moments of Pr3+ ions implies that the associate, longitudinally polarized magnetic excitations are more intense and dispersive than the usual transverse spin waves. Within the rando

Traditional water management techniques – do they have a role in post Arab Spring Middle East?

Traditional management of scarce water resources has been practiced in the Middle East for thousands of years. They were developed to encompass a sustainable agricultural production in spite of small rainfall amounts in often harsh arid to semiarid environments with poor soil quality (e.g., jessour, tabiah, meskat, khooshab, qanat). Due to their efficiency, revitalized systems have been suggested

Shock-wave behaviour of sedimentation in wastewater treatment: a rich problem

A common industrial process for separating particles from a liquid is continuous sedimentation, which is used in the chemical, mining, pulp-and-paper and food industries. It can also be found in most wastewater treatment plants, where it is a crucial subprocess of a complex biological system. The process has provided, and will continue to provide, scientific problems that lead to fundamental resea

Activity-dependent long-term plasticity of afferent synapses on grafted stem/progenitor cell-derived neurons.

Stem cell-based cell replacement therapies aiming at restoring injured or diseased brain function ultimately rely on the capability of transplanted cells to promote functional recovery. The mechanisms by which stem cell-based therapies for neurological conditions can lead to functional recovery are uncertain, but structural and functional repair appears to depend on integration of transplanted cel

Neurochemical measures co-vary with personality traits: Forensic psychiatric findings replicated in a general population sample

Neurobiological markers in cerebrospinal fluid (CSF) and in serum, previously found to co-vary with destructive personality traits in violent offenders, were explored in a general population sample of 21 patients undergoing knee surgery. Results on the Karolinska Scales of Personality (KSP) and the Temperament and Character Inventory (TCI) were compared with CSF/serum albumin ratios and serum conc

Exposure to respirable dust and manganese and prevalence of airways symptoms, among Swedish mild steel welders in the manufacturing industry.

Welding fume consists of metal fumes, e.g., manganese (Mn) and gases, e.g., ozone. Particles in the respirable dust (RD) size range dominate. Exposure to welding fume could cause short- and long-term respiratory effects. The prevalence of work-related symptoms among mild steel welders was studied, and the occupational exposure to welding fumes was quantified by repeated measurements of RD, respira

Prevalence and Severity of Undetected Manifest Glaucoma: Results from the Early Manifest Glaucoma Trial Screening.

PURPOSE: To estimate the prevalence and severity of undetected glaucoma in the population. DESIGN: Cross-sectional study. PARTICIPANTS: A total of 32 918 subjects aged 55 to 79 years from Malmö, Sweden, who were screened between 1992 and 1997. All subjects in the screened age groups living in the catchment area, and for whom there were no recent records at the Malmö University Hospital Ophthalmolo

Interpreting canopy development and physiology using a European phenology camera network at flux sites

Plant phenological development is orchestrated through subtle changes in photoperiod, temperature, soil moisture and nutrient availability. Presently, the exact timing of plant development stages and their response to climate and management practices are crudely represented in land surface models. As visual observations of phenology are laborious, there is a need to supplement long-term observatio

Fluorescence enhancement of single DNA molecules confined in Si/SiO2 nanochannels

We demonstrate that the detected emission intensity from YOYO-labeled DNA molecules confined in 180 nm deep Si/SiO2 nano-funnels changes significantly and not monotonically with the width of the funnel. This effect may be of importance for quantitative fluorescence microscopy and for experiments with a tight photon budget.

Landscape-scale crop diversity interacts with local management to determine ground beetle diversity

Crop diversification and maintenance of semi-natural habitats (grasslands and field boundaries) are suggested to enhance farmland biodiversity, but the relative importance of these factors remains poorly known. We evaluated how crop diversity and availability of semi-natural grasslands at a landscape-scale interacted with local farming management (three management types from low to high intensity:

Complexity of a classical flow restoration problem

In this article, we revisit a classical optimization problem occurring in designing survivable multicommodity flow networks. The problem, referred to as FR, assumes flow restoration that takes advantage of the so-called stub release. As no compact linear programming (LP) formulation of FR is known and at the same time all known noncompact LP formulations of FR exhibit NP-hard dual separation, the

Reliability of plastic cups to measure breast volume.

Abstract Breast volume measurement is valuable in clinical practice, and various methods have been used. Nonetheless, no commonly accepted standard technique exists for clinical everyday use and there is no optimal method that is quick, cheap, minimally invasive, and acceptable for the patient and for the surgeon. Previously, a study has shown that the volume measured with plastic cups differed li

A blind trilobite with Baltic affinities from Cambrian Series 3 of the Iberian Chains, Spain, and its stratigraphical and palaeobiogeographical significance

Three cranidia of a conocoryphid trilobite are described from the lower Caesaraugustan Regional Stage (upper part of provisional Cambrian Stage 5 within Cambrian Series 3) in the Iberian Chains, Spain. The material is from the upper part of the Mansilla Formation and the base of the overlying Murero Formation. It closely resembles Bailiella tenuicincta (Linnarsson, 1879), which has previously been
