We report the development of a high-level bacterial expression system for the Alzheimer's disease-associated amyloid beta-peptide (A beta), together with a scaleable and inexpensive purification procedure. A beta(1-40) and A beta(1-42) coding sequences together with added ATG codons were cloned directly into a Pet vector to facilitate production of Met-A beta(1-40) and Met-A beta(1-42), referred t

BACKGROUND: Despite marked improvement in therapy and monitoring of patients with insulin-dependent (type 1) diabetes, diabetic nephropathy remains a serious complication, with subsequent end-stage renal disease in about 20% of cases. OBJECTIVE: To investigate in young patients with type 1 diabetes whether urine α-Glutathione S-transferase to creatinine ratio (α-GST:crea) relates to markers of s

Objectives: To examine the risk of putative pneumococcal infections in adult arthritis patients on different anti-rheumatic drugs immunized with heptavalent pneumococcal conjugate vaccine (Prevenar 7; PCV7) and non-vaccinated individually matched arthritis patients. Method: All individuals in a cohort of 505 patients with rheumatoid arthritis (RA) or spondylarthropathy (SpA) receiving different an

Introduction Many kinds of footwear are used for various purposes in the workplace in Japan. Careful selection of footwear is needed to protect workers from coldness and to keep the performance of workers in cold workplace where employees have to work under -20℃. On the other hand, safety boots with high heat conductivity from foot to outside are needed for the workers in hot environments. But the

Background: We aimed to investigate the diagnostic performance of S100 as an outcome predictor after out-of-hospital cardiac arrest (OHCA) and the potential influence of two target temperatures (33 °C and 36 °C) on serum levels of S100. Methods: This is a substudy of the Target Temperature Management after Out-of-Hospital Cardiac Arrest (TTM) trial. Serum levels of S100 were measured a posteriori

Malignant melanoma is a heterogeneous, malignant neoplastic disease, most often originating in the skin. Melanoma is characterized by a high mutational load and has a vastly variable prognosis, depending on disease stage. Genetic aberrations in the mitogen-activating protein kinase (MAPK) pathway are important in melanoma, of which mutations in BRAF and NRAS are the most common. Additionally, recu

Objective: The aim of this systematic review and meta-analysis (SR-MA) was to identify signaling molecule profiles and blood-derived biomarkers in migraine and cluster headache (CH) patients. Background: Currently no migraine and CH valid biomarkers are available. Blood tests based on biomarker profiles have been used to gather information about the nervous system. Such tests have not yet been est

The effect of the procedural variability in image acquisition on the quantitative assessment of bone scan is unknown. Here, we have developed and performed preanalytical studies to assess the impact of the variability in scanning speed and in vendor-specific γ-camera on reproducibility and accuracy of the automated bone scan index (BSI). Methods: Two separate preanalytical studies were performed:

Objective: To determine the true incidence of complete uterine rupture and uterine dehiscence among women delivered by cesarean section after a previous cesarean section. Methods: Medical records of all women who delivered at University Hospital in Malmö, Sweden, during 2005–2009 (n = 21 420) were retrieved from the electronic patient record system (EPRS). After adjustment for inaccuracies, 716 wo

The MAX IV facility in Lund, Sweden consists of two storage rings for production of synchrotron radiation. The smaller 1.5 GeV ring is presently under construction, while the larger 3 GeV ring is being commissioned. Both rings will be operating with top-up injections from a full-energy injector. During injection, the electron beam is first delivered to the main injector from a thermionic pre-injec

Fires in the Wildland-Urban Interface (WUI) areas is a worldwide problem, which is gaining more importance over time due to climate change and constructions in the WUI areas. Standards and guidelines may greatly help the activities of planning, prevention and protection against wildfires. Some countries/States/local communities can already rely on existing standards and guidelines, while other are

MYH9-related platelet disorders are inherited macrothrombocytopenias with additional clinical manifestations including renal failure, hearing loss, pre-senile cataract, and inclusion bodies in leucocytes that are present in different combinations. The MYH9 gene codes for the cytoplasmic contractile protein non-muscular myosin heavy chain IIA, present in several tissues. The bleeding tendency is us

OBJECTIVES: the purpose of this study was to assess the predictive accuracy of conventional cardiovascular risk factors for incident heart failure and atrial fibrillation, and the added benefit of multiple biomarkers reflecting diverse pathophysiological pathways. BACKGROUND: heart failure and atrial fibrillation are interrelated cardiac diseases associated with substantial morbidity and mortality

Popular Abstract in Swedish Sjukdomen ärftlig hjärnblödning med cystatin C-amyloid angiopati (engelsk förkortning, HCCAA) beror på att en ärftlig mutation i genomet förändrar en byggsten (aminosyra) i proteinet cystatin C. Cystatin C-varianten som uppkommer deponeras som olösligt material (amyloid) i blodkärlens väggar och leder till att dessa ofta brister före 40-årsåldern med hjärnblödning som fHereditary cystatin C amyloid angiopathy (HCCAA) is a disorder characterised by multiple strokes in young adults, resulting in paralysis and dementia. The disease is caused by a mutation in the gene coding for the peptidase inhibitor cystatin C. The mutation causes an amino acid substitution Leu68 -> Gln in cystatin C (L68Q cystatin C) which results in deposition of the protein in the blood vessel

BACKGROUND: During the two recent decades, advocacy has been a topic of much debate in the nursing profession. Although advocacy has embraced a crucial role for nurses, its extent is often limited in practice. While a variety of studies have been generated all over the world, barriers and facilitators in the patient advocacy have not been completely identified. This article presents the findings o

Data concerning the persistent reduction of flow velocities measured by transcranial color-coded sonography (TCCS) in relation to the clinical and radiological outcome among patients with ischemic events in middle cerebral artery (MCA) territory is scarce. Patients with > or = 50% reduction of peak systolic velocities (PSV-MCA) as compared to the contralateral MCA were prospectively included in fo

OBJECTIVE: To study intra-aneurysm sac pressure and subsequent abdominal aortic aneurysm (AAA) diameter changes in patients without endoleaks that remain unchanged in AAA diameter more than 1 year after endovascular aneurysm repair (EVAR). METHODS: A total of 23 patients underwent direct intra-aneurysm sac pressure (DISP) measurements 16 months (IQR: 14-35 months) after EVAR. Tip-pressure sensors

Interaction, communication and signification are fundamental to the human world. How do children use codes in their drawings, as in-struments of processing information, representing reality? I find use-ful tools in theories that focus upon the semiotic play, thought and language. The object of my study has been to analyze and describe children´s pictorial sign vehicle, in order to find the relatio
