Background: The survival of patients with locally advanced head and neck cancer is still poor, with 5-year survival rates of 24-35%. The identification of prognostic and predictive markers at the molecular and cellular level could make it possible to find new therapeutic targets and provide "taylor made" treatments. Established cell lines of human squamous cell carcinoma (HNSCC) are valuable model

A state-of-the-art 3D source imaging technique is used to extract the 3D two-pion source function in central and mid-central Au+Au collisions at GeV. The source function indicates a previously unresolved non-Gaussian tail in the directions of the pion pair transverse momentum (out) and along the beam (long). Model comparisons give robust estimates for several characteristics of the emission source

The current study evaluated amyloid-beta oligomers (A beta o) in cerebrospinal fluid as a clinical biomarker for Alzheimer's disease (AD). We developed a highly sensitive A beta o ELISA using the same N-terminal monoclonal antibody (82E1) for capture and detection. CSF samples from patients with AD, mild cognitive impairment (MCI), and healthy controls were examined. The assay was specific for oli

An essential part of a performance-based service life design format for wood exposed in outdoor applications is the effect of proper detailing in terms of avoiding moisture traps. Models for predicting degradation and non-performance caused by decay are functions of arbitrary climate history of combined moisture content and temperature. Therefore it is crucial to be able to predict the behaviour o

Basement membranes (BMs) are sheet-like structures of extracellular matrix. They act as a supporting structure but can also significantly influence cellular behavior in development, tissue homeostasis and disease. Laminins, a major BM component, are multidomain proteins, consisting of three polypeptide chains (α, β and γ). During pregastrulation development, stem cells convert and epithelial tissu

Heavy metals can cause renal effects on vulnerable populations but it is uncertain whether these metals still pose health risks at the low exposure levels now prevailing in most industrialized countries. In a cross-sectional study performed on 736 adolescents, we assessed the associations between the concentrations of cadmium and lead in blood and urine and the urinary concentrations of albumin an

Sera from 25 metastatic breast cancer patients and 25 healthy controls were subjected to affinity chromatography using immobilized galectin-1. Serum from the healthy subjects contained on average 1.2 mg per ml (range 0.7-2.2) galectin-1 binding glycoproteins, whereas serum from the breast cancer patients contained on average 2.2 mg/ml (range 0.8-3.9), with a higher average for large primary tumour

This study highlights the expansion of butterflies and macromoths occurring in southern Sweden. Recent changes in climate and habitat has been stressed as the main factors influencing changes in species distributions. Climate change implies an increase in temperature and some species are assumed to extend their northern ranges. In this study we compiled information about the first observations of

Förmåga att använda informations- och kommunikationsteknik framhålls numera ofta som en förutsättning för delaktighet på lika villkor i samhällslivet. Nära förknippat med detta är de insatser som görs för att överbrygga digitala klyftor i samhället. IKT har gjort deltagandet i samhällslivet mer möjligt för personer med synnedsättning. Tillgång till teknik innebär dock inte alltid att den kan använ

This field experiment investigated how C from fresh organic amendments and from a growing leek crop was allocated into different soil microbial and faunal groups in an arable field. A C-13-enriched red clover green manure was incorporated in one treatment, while the growing leek crop was pulse labelled with (CO2)-C-13 in another. Incorporation of C-13 into microbial fatty acids, micro- and macroar

The Universal Thermal Climate Index (UTCI) was conceived as a thermal index covering the whole climate range from heat to cold. This would be impossible without considering clothing as the interface between the person (here, the physiological model of thermoregulation) and the environment. It was decided to develop a clothing model for this application in which the following three factors were con

Background. The aim of this study was to determine the incidence of pre- and postoperative vomiting in children undergoing a Video-Assisted Gastrostomy (VAG) operation. Patients and Methods. 180 children underwent a VAG operation and were subdivided into groups based on their underlying diagnosis. An anamnesis with respect to vomiting was taken from each of the children's parents before the operat

The expression levels of fetal hemoglobin (HbF) in bacterial recombinant systems are higher compared with normal adult hemoglobin (HbA). However, heme disorientation in globins are often observed in recombinant production processes, both for HbA and HbF, although the degree of heme oriental disorder is much lower for HbF. In addition, the heme disorientation can be converted to a normal conformati

Context: Several studies suggest a link between increased activity of the inflammatory inhibitor-kappaB kinase/nuclear factor-kappaB (IKK/NF-kappaB) pathway in skeletal muscle and insulin resistance. Objective: We aimed to study the regulation of skeletal muscle IKK/NF-kappaB pathway activity as well as the association with glucose metabolism and skeletal muscle insulin signaling. Methods: The stu

Epidemiological studies have shown direct associations between type 2 diabetes and obesity, both conditions associated with hyperglycaemia and hyperinsulinemia, and the risk of pancreatic cancer. Up to 80% of pancreatic cancer patients present with either new-onset type 2 diabetes or impaired glucose tolerance at the time of diagnosis. Recent population studies indicate that the incidence of pancr
