External and internal factors influencing self-directed online learning of physiotherapy undergraduate students in Sweden: a qualitative study.

Online courses have become common in health sciences education. This learning environment can be designed using different approaches to support student learning. To further develop online environment, it is important to understand how students perceive working and learning online. The aim of this study is to identify aspects influencing students' learning processes and their adaptation to self-dir

Image analysis of prostate cancer tissue biomarkers

Popular Abstract in English Prostate cancer is one of the most common cancers in the world and the second most common in men. The western world has the highest incidence rates. The causes of prostate cancer are not yet clear, however a number of risk factors have been identified such as familial history, ethnicity, diet and genetic events. Prostate cancer affects primarily elderly men with the majProstate cancer is the second most common cancer in men. In order to improve diagnosis and prognosis, new sensitive and specific biomarkers are needed. Tissue biomarkers carry expression and morphological information of the tissue where they are expressed. However their use is still limited by technological problems, lack of standardized procedures and inadequate interpretation. In this work we in

Cerebellar cortical neuron responses evoked from the spinal border cell tract.

Spinocerebellar systems are likely to be crucial for cerebellar hallmark functions such as coordination. However, in terms of cerebellar functional analyses, these are perhaps among the least explored systems. The aim of the present study is to achieve activation of a single component of the spinocerebellar systems and to explore to what extent it can influence the spike output of granule cells, G

450K-array analysis of chronic lymphocytic leukemia cells reveals global DNA methylation to be relatively stable over time and similar in resting and proliferative compartments

In chronic lymphocytic leukemia (CLL), the microenvironment influences gene expression patterns; however, knowledge is limited regarding the extent to which methylation changes with time and exposure to specific microenvironments. Using high-resolution 450K arrays, we provide the most comprehensive DNA methylation study of CLL to date, analyzing paired diagnostic/follow-up samples from IGHV-mutate

Opioids for Chronic Refractory Breathlessness: Right Patient, Right Route?

Chronic breathlessness at rest or on minimal exertion despite optimal treatment of the underlying chronic cause(s) is termed chronic refractory breathlessness. This is prevalent across the community and is an independent indicator of poor prognosis. This narrative review focuses on the palliation of chronic refractory breathlessness in people predominantly with non-cancer diagnoses. Breathlessness

Trötta mammors försvarare : familjevärderingar i Kerstin Thorvalls bilderböcker från 1970-talet

Kerstin Thorvall (1925–2010) is a Swedish author of books for children and young adults, as well as books for adults. In 1965, she wrote the article “Do all authors of children's books live in Tomtebolandet?” (“Bor alla barnboksförfattare i Tomtebolandet”, Expressen 1965) in which she claims that gender roles in Swedish children's literature, are depicted in an old and stereotypical fashion. She a

Can variability in the effect of opioids on refractory breathlessness be explained by genetic factors?

Opioids modulate the perception of breathlessness with a considerable variation in response, with poor correlation between the required opioid dose and symptom severity. The objective of this hypothesis-generating, secondary analysis was to identify candidate single nucleotide polymorphisms (SNP) from those associated with opioid receptors, signalling or pain modulation to identify any related to

Safety of thalidomide in newly diagnosed elderly myeloma patients: a meta-analysis of data from individual patients in six randomized trials

Treatment with melphalan-prednisone-thalidomide improves the outcome of patients with multiple myeloma and is now considered a standard of care for patients not eligible for transplantation. However, this treatment is a major source of morbidity. A meta-analysis of data from individual patients (n=1680) in six randomized trials was performed, comparing the effects of melphalan-prednisone-thalidomi

Promoting work ability in a structured national rehabilitation program in patients with musculoskeletal disorders: outcomes and predictors in a prospective cohort study

Background: Musculoskeletal disorders (MSDs) are a major reason for impaired work productivity and sick leave. In 2009, a national rehabilitation program was introduced in Sweden to promote work ability, and patients with MSDs were offered multimodal rehabilitation. The aim of this study was to analyse the effect of this program on health related quality of life, function, sick leave and work abil

LPL is the strongest prognostic factor in a comparative analysis of RNA-based markers in early chronic lymphocytic leukemia

Background The expression levels of LPL, ZAP70, TCL1A, CLLU1 and MCL1 have recently been proposed as prognostic factors in chronic lymphocytic leukemia. However, few studies have systematically compared these different RNA-based markers. Design and Methods Using real-time quantitative PCR, we measured the mRNA expression levels of these genes in unsorted samples from 252 newly diagnosed chronic ly

Förslag till ett samverkanssystem för svenska länsstyrelser

This report is a first attempt to use the design perspective we have developed in earlier reports in this series (Brehmer & Tehler, 2013: Tehler & Brehmer, 2013) in practical design of a system that would help Swedish County Administration Boards to meet their area responsibility in cases of major crises and accidents in their counties. The work starts with the development of a design hier

Scalable, high performance, enzymatic cathodes based on nanoimprint lithography

Here we detail high performance, enzymatic electrodes for oxygen bio-electroreduction, which can be easily and reproducibly fabricated with industry-scale throughput. Planar and nanostructured electrodes were built on biocompatible, flexible polymer sheets, while nanoimprint lithography was used for electrode nanostructuring. To the best of our knowledge, this is one of the first reports concernin

The influence of nanoparticles on enzymatic bioelectrocatalysis

In nearly all papers concerning enzyme-nanoparticle based bio-electronic devices, it is stated that the presence of nanoparticles on electrode surfaces per se enhances bioelectrocatalysis, although the reasons for that enhancement are often unclear. Here, we report detailed experimental evidence that neither an overpotential of bioelectrocatalysis, nor direct electron transfer and bioelectrocataly

Osteoclasts promote the formation of hematopoietic stem cell niches in the bone marrow

Formation of the hematopoietic stem cell (HSC) niche in bone marrow (BM) is tightly associated with endochondral ossification, but little is known about the mechanisms involved. We used the oc/oc mouse, a mouse model with impaired endochondral ossification caused by a loss of osteoclast (OCL) activity, to investigate the role of osteoblasts (OBLs) and OCLs in the HSC niche formation. The absence o

Cardiac cell identification and isolation

Identification and isolation of cardiomyocytes from the heart, embryonic stem cells, or induced pluripotent stem cells is a challenging task and will require specific isolation techniques. Less than 30% of the cells within the murine heart are cardiomyocytes and, what is more, there are multiple sub-populations of cardiomyocytes like atrial, ventricular and conduction system cardiomyocytes. In Pap

An Audit-Based, Infectious Disease Specialist-Guided Antimicrobial Stewardship Program Profoundly Reduced Antibiotic Use Without Negatively Affecting Patient Outcomes.

Background. Antimicrobial stewardship programs are increasingly implemented in hospital care. They aim to simultaneously optimize outcomes for individual patients with infections and reduce financial and health-associated costs of overuse of antibiotics. Few studies have examined the effects of antimicrobial stewardship programs in settings with low proportions of antimicrobial resistance, such as

Strong Schottky barrier reduction at Au-catalyst/GaAs-nanowire interfaces by electric dipole formation and Fermi-level unpinning

Nanoscale contacts between metals and semiconductors are critical for further downscaling of electronic and optoelectronic devices. However, realizing nanocontacts poses significant challenges since conventional approaches to achieve ohmic contacts through Schottky barrier suppression are often inadequate. Here we report the realization and characterization of low n-type Schottky barriers (~0.35 e
