The word crisis is often used in everyday language, but according to political theory it actually refers to a crisis situation within a country where national interests suddenly are at stake demanding that important and complex decisions must be made within certain time constraints. These decisions can in turn lead up to most fatal consequences. USA, being one of the world's superpowers is mos
The current status of overexploited fish stocks worldwide and increasing stakeholder expectations that retailers should responsibly source products have led to an increasing number of food retailers committing to sell sustainable seafood. Yet, the complexity and variety of seafood supply chains and the challenge inherent in the verification of sustainability qualities suggest that the implementati
Cellular signalling and potential agents to combat prostate cancer Prostate cancer (PCa) arises as a result of uncontrolled proliferation of the cells in the male prostate gland. The male androgenic hormone, testosterone fuels prostate cancer cells. In the cells of the prostate, the androgen receptor (AR) acts as the signal receiver and effector of androgen, ultimately leading to the growth and s
This essay provides an analysis of the relation between the value added tax (VAT) and the size of the informal sector in Africa. The proposed hypothesis is that due to incentive mechanisms provided by VAT, tax evasion, and hence the size of the informal sector, should decrease when VAT replaces other standard consumption taxes, primarily the retail sales tax (RST) and the turnover tax (TOT). The
The objective of this study is to increase the knowledge regarding school principals’work situations by examining the associations between various factors and the school principals’assessments of their ability or wish to work until 65 years of age or longer. The 1356 participatingschool principals in this study were aged between 50 and 64 years of age. Individual and workfactors were evaluated in
A measurement of the ZZ production cross section in proton-proton collisions at root s = 7 TeV using data corresponding to an integrated luminosity of 1.02 fb(-1) recorded by the ATLAS experiment at the LHC is presented. Twelve events containing two Z boson candidates decaying to electrons and/or muons are observed, with an expected background of 0.3 +/- 0.3(stat)(-0.3)(+0.4)(syst) events. The cro
Background and purpose — Modular-neck hip stems have been identified with corrosion-related problems from the neck–stem junction. We report an ongoing varus deformity of modular-neck hip stems with simultaneous metal ion release observed during a study comparing the migration of modular vs. standard hip stems. Patients and methods — We followed 50 patients with modular and 25 with standard neck st
Objectives Study the proportion of patients affected by involuntary childlessness who are denied fertility treatment and the reasons behind this in a publicly funded healthcare system. Design Survey study using prospectively collected information by healthcare professionals. Setting Two university-affiliated fertility clinics in Sweden. Participants Single women and couples in heterosexual and hom
Various benthic mapping methods exist but financing and technical capacity limit the choice of technology available to developing states to aid with natural resource management. Therefore, we assessed the efficacy of using a single-beam echosounder (SBES), satellite images (GeoEye-1 and WorldView-2) and different image (pixel-based Maximum Likelihood Classifier (MLC), and an objectbased image anal
This study investigated the effect of biogenic AgNPs on seed germination and seedling growth of Solanum lycopersicum. Treatment with silver nanoparticles (AgNPs) showed a significantly high germination rate and seedling growth compared to untreated seeds. Furthermore, its bactericidal effect against bacterial pathogen Clavibacter michiganensis subsp. michiganensis (cmm) infection in Solanum lycope
Artikeln presenterar svensk senmedeltida helgonpredikan i allmänhet, några generella drag hos de ca 30 bevarade predikningarna om S:t Olof samt en mer ingående redogörelse för en av dessa.The contribution presents preserved medieval Nordic sermons on St Olaf, all of which are found in Latin manuscripts from the medieval library of Vadstena Abbey. After a brief discussion of what they sermons say about St Olaf and what sources the preachers may have used, the contents of one specific sermon are given in summary form.
Objective. To analyze the characteristics of anti-RNA polymerase III antibodies (anti-RNAP3)- positive patients with systemic sclerosis (SSc) in the European League Against Rheumatism Scleroderma Trials and Research group (EUSTAR) registry with a focus on the risk of cancer and the characteristics of malignancies, and the aim to provide guidelines about potential cancer screening in these patients
Ferritin heavy chain (FTH1) is a 21-kDa subunit of the ferritin complex, known for its role in iron metabolism, and which has recently been identified as a favorable prognostic protein for triple negative breast cancer (TNBC) patients. Currently, it is not well understood how FTH1 contributes to an anti-tumor response. Here, we explored whether expression and cellular compartmentalization of FTH1
Succinate dehydrogenase consists of two protein subunits and contains one FAD and three iron-sulfur clusters. The flavin is covalently bound to a histidine in the larger, Fp, subunit. The reduction oxidation midpoint potentials of the clusters designated S-l, S-2, and S-3 in Bacillus subtilis wild-type membrane-bound enzyme were determined as +80, -240, and -25 mV, respectively. Magnetic spin int
Background: Periarticular osteopenia is an early sign of incipient joint injury in rheumatoid arthritis (RA), but cannot be accurately quantified using conventional radiography. Digital X-ray radiogrammetry (DXR) is a computerized technique to estimate bone mineral density (BMD) from hand radiographs. The aim of this study was to evaluate whether decrease in BMD of the hands (BMD loss), as determi
Ascorbate-induced release of heparan sulfate from S-nitrosylated heparan sulfate proteoglycan glypican-1 takes place in endosomes. Heparan sulfate penetrates the membrane and is transported to the nucleus. This process is dependent on copper and on expression and processing of the amyloid precursor protein. It remains unclear how exogenously supplied ascorbate can generate HS-anMan in endosomes an
