The electrospun carbon nanofibers obtained from polyacrylonitrile (PAN) and PAN blends with either activated carbon (PAN-AC) or graphite (PAN-GR) were tested as anodes using Shewanella oneidensis MR-1. Extensive physico-chemical and electrochemical characterization confirmed their formation, their fibrous and porous nature, and their suitability as electrodes. N(2) adsorption measurements revealed
Sweden has never before had so many serving life sentences. Anyone sentenced to life imprisonment has the opportunity to apply to have their sentence fixed by a court. In that examination, the court must take into account various factors, including whether there is a risk that the lifer will relapse into serious crime. To help answer that question, the court has a statement from the National Board
When developing products, engineering designers often face the problem that their candidate for a technical solution, ranging from a concept to a detailed design, needs to be analyzed by a design analyst before it is approved or rejected and the engineering designer can continue his/her activities within the product development process. If engineering designers have to send every solution candidat
Background: The quantification of the relationships between walking and health requires that walking is measured accurately. We correlated different measures of step accumulation to body size, overall physical activity level, and glucose regulation. Methods: Participants were 25 men and 25 women American Indians without diabetes (Age: 20-34 years) in Phoenix, Arizona, USA. We assessed steps/day du
P>Aims Type 1 diabetes mellitus (T1DM) is an autoimmune disease with potential mechanistic links to immune-related cancers. We aimed at examining the overall and specific cancer risks among hospitalized T1DM patients from the national registers in Sweden. Methods A T1DM research cohort was created by identifying T1DM patients from the Hospital Discharge Register and linking them with the Cancer Re
Increasing demands for highly sensitive, accurate, fast and portable analytical assays have led to the development of new analytical tools. The integration of highly specific biological sensing elements and appropriate transducers has enabled design of even more efficient biosensor devices for the detection of target substances. In a clinical setting, early detection of biomarkers is crucial for
Here, we present an unusual approach of modifying the growth pattern of electroactive bacteria for improving their communication with electrodes. Cells of a known exoelectrogen, Shewanella oneidensis MR-1, were treated with cisplatin, a drug that inhibits cell division but forces the cells to grow longer resulting in a characteristic elongated growth. Such elongated cells showed up to a 5-fold imp
Objective: To determine the association between radiographic osteoarthritis (OA) and pre-operative function in patients undergoing primary knee replacement. Methods: Single centre study examining pre-operative outcomes in a consecutive series of 525 patients who underwent primary knee replacement for OA between January 2006 and December 2007. Pre-operative data included: demographics, American Soc
Widespread negative correlations between summertime-mean temperatures and precipitation over land regions are a well-known feature of terrestrial climate. This behavior has generally been interpreted in the context of soil moisture atmosphere coupling, with soil moisture deficits associated with reduced rainfall leading to enhanced surface sensible heating and higher surface temperature. The prese
Genome wide association studies (GWAS) identify susceptibility loci for complex traits, but do not identify particular genes of interest. Integration of functional and network information may help in overcoming this limitation and identifying new susceptibility loci. Using GWAS and comorbidity data, we present a network-based approach to predict candidate genes for lipid and lipoprotein traits. We
Background: The aim was to investigate whether the effects of major risk factors for ischemic stroke were modified by long-term exposure to air pollution in Scania, southern Sweden. Methods: Cases were defined as first-ever ischemic strokes in patients born between 1923 and 1965 during 2001-2006 (n = 7,244). Data were collected from The Swedish National Stroke Register (Riks-stroke) and the Malmo
CONTEXT: Prior research suggests that drug abuse (DA) is strongly influenced by both genetic and familial environmental factors. No large-scale adoption study has previously attempted to verify and integrate these findings. OBJECTIVE: To determine how genetic and environmental factors contribute to the risk for DA. DESIGN: Follow-up in 9 public databases (1961-2009) of adopted children and their
Objective The Systemic Lupus International Collaborating Clinics (SLICC) group revised and validated the American College of Rheumatology (ACR) systemic lupus erythematosus (SLE) classification criteria in order to improve clinical relevance, meet stringent methodology requirements, and incorporate new knowledge regarding the immunology of SLE. Methods The classification criteria were derived from
We hypothesized that a low grade in physical education (PE) is associated with an increased risk of future musculoskeletal conditions, especially chronic pain. Using a historical cohort study design, we identified all students (mean age 16.0years), who in 1974-1976 graduated from compulsory school in a Swedish municipality and retrieved their PE grades. We ensured that persons were still alive and
The remarkable advancements in basic stem cell research with implications for several central nervous system disorders have so far not been translated into clinically effective therapies. Here I discuss some of the underlying problems and how they could be overcome.
