Antisymmetric magneto-resistance anomalies generated by a reversal of the magnetization are studied in a number of GaMnAs/InGaAs layers with out-of-plane (easy axis) magnetization. The anomalies occur independent of the magnetic field orientation. This shows, that once a magnetic domain with reversed magnetization is nucleated, simply the presence of the domain wall between the longitudinal contac
Translating new findings in the laboratory into therapies for patients is a slow and expensive process. The development of therapies for neurodegenerative diseases is further complicated by the difficulty in determining whether the drug truly retards the slow degenerative process or provides only symptomatic benefit. In this issue, Aviles-Olmos et al. describe a first in Parkinson's disease (PD) p
Background: The involvement of aquaporin (AQP) water and small solute channels in the etiology of several diseases, including cancer, neuromyelitis optica and body fluid imbalance disorders, has been suggested previously. Furthermore, results obtained in a mouse model suggested that AQP9 function contributes to hyperglycemia in type-2 diabetes. In addition, the physiological role of several AQP fa
How the molecular programs of differentiated cells develop as cells transit from multipotency through lineage commitment remains unexplored. This reflects the inability to access cells undergoing commitment or located in the immediate vicinity of commitment boundaries. It remains unclear whether commitment constitutes a gradual process, or else represents a discrete transition. Analyses of in vitr
Background: Cohort studies of the relationship between air pollution exposure and chronic health effects require predictions of exposure over long periods of time. Objectives: We developed a unified modeling approach for predicting fine particulate matter, nitrogen dioxide, oxides of nitrogen, and black carbon (as measured by light absorption coefficient) in six U.S. metropolitan regions from 1999
Introduction: There is a shortage of tools designed for use by occupational therapy practice in Arabic-speaking countries. The purpose of this study was to translate and cross-culturally adapt the original Satisfaction with Daily Occupations tool to Arabic and assess the psychometric properties of the adapted tool. Method: A cross-cultural adaptation process was performed. Face, content, and crite
New types of knowledge, and new ways of organising the production of it, may emerge as knowledge producers respond to the challenges posed by a changing society. This paper focuses on the core knowledge of one such emerging field, namely, innovation studies. To explore the knowledge base of the field, a database of references in scholarly surveys of various aspects of innovation, published in "han
A bioanode with high current density and coulombic efficiency was developed by co-immobilization of pyranose dehydrogenase from Agaricus meleagris (AmPDH) with the dehydrogenase domain of cellobiose dehydrogenase from Corynascus thermophiles (recDHCtCDH) expressed recombinantly in Escherichia coli. The two enzymes were entrapped in Os-complex modified electrodeposition polymers (Os-EDPs) with spec
Protein C inhibitor (PCI) is a serine protease inhibitor and was originally identified as an inhibitor of activated protein C (APC). However, PCI is not specific for APC and also inhibits several proteases involved in coagulation, fibrinolysis, cancer, wound healing, and fertility. The biological function of PCI is unknown due to broad enzyme specificity, its wide tissue distribution, and the lack
The Branched Chain Saturated Alcohol (BCSA) group of fragrance ingredients was evaluated for safety. In humans, no evidence of skin irritation was found at concentrations of 2-10%. Undiluted, 11 materials evaluated caused moderate to severe eye irritation. As current end product use levels are between 0.001% and 1.7%, eye irritation is not a concern. The materials have no or low sensitizing potent

Detailed analysis of data from studies of recombinant antihemophilic factor produced using a plasma/albumin-free method (rAHF-PFM) in previously treated patients showed a substantial level of interpatient variation in pharmacokinetics (PKs), factor VIII dosing, and annualized bleed rate (ABR), suggesting that individual patient characteristics contributed to outcome. For example, plasma half-life
The paper seeks to advance our understanding of the extent to which the use of economic incentives can undermine ("crowd out") or reinforce ("crowd in") people's intrinsic motivations to engage in biodiversity and ecosystem conservation. We first synthesize and classify the psychological mechanisms behind motivation crowding effects. Then we conduct a systematic review of empirical studies that te
Well-developed oncoids and centimetre-sized stromatolites are reported for the first time from the Darriwilian (Middle Ordovician) cool-water orthoceratite limestone' at Kinnekulle, Vastergotland, Sweden. The characteristics and stratigraphical distribution of these microbialites show an apparent relationship to fluctuations in relative sea level. The most abundant and well-developed oncoids occur
A service transition is supposed to lead to the decline of energy intensity (energy/GDP). We argue that this interpretation is overly optimistic because the shift to a service economy is somewhat of an illusion in terms of real production. Several recent studies of structural effects on energy intensity have made the error of using sector shares in current prices, combined with GDP in constant pri
Objectives To describe the prevalence and longitudinal course of radiographic, erosive and symptomatic hand osteoarthritis (HOA) in the general population. Methods Framingham osteoarthritis (OA) study participants obtained bilateral hand radiographs at baseline and 9-year follow-up. The authors defined radiographic HOA at joint level as Kellgren-Lawrence grade (KLG)>= 2, erosive HOA as KLG >= 2 pl
Sea buckthorn berries contain many bioactive compounds that have anticancer properties. To investigate whether the anti proliferative effects Could be associated with the presence of certain compounds. a sequential extraction was performed. The extraction started with heptane followed by ethyl acetate, ethanol, and water. A second protocol using ethanol:water (1:1) was also used. The contents of t
Popular Abstract in Swedish Prostatacancer drabbar män över hela världen; i Sverige får ungefär 10 000 personer diagnosen varje år. För den enskilda individen kan följderna innebära fysiskt och psykiskt lidande, men även samhället belastas med höga vårdkostnader. För att undvika onödigt lidande, men också minska kostnaderna är det nödvändigt att ta fram nya läkemedel och metoder för att i god tid The aims of this thesis were to identify microRNAs (miRNAs) with prostate cancer prognostic and diagnostic potential, to discover miRNAs with therapeutic capacity against prostate cancer, and to investigate if prostate specific antigen (PSA) is miRNA regulated. Prostate cancer is a globally spread disease with low mortality, but some patients develop an aggressive lethal form of prostate cancer w
