FACS binding assay for analysing GDNF interactions.

Glial cell-line derived neurotrophic factor (GDNF) is a secreted protein with great therapeutic potential. However, in order to analyse the interactions between GDNF and its receptors, researchers have been mostly dependent of radioactive binding assays. We developed a FACS-based binding assay for GDNF as an alternative to current methods. We demonstrated that the FACS-based assay using TGW cells

APOE genotype and extent of bleeding and outcome in lobar intracerebral haemorrhage: a genetic association study

Background Carriers of APOE epsilon 2 and epsilon 4 have an increased risk of intracerebral haemorrhage (ICH) in lobar regions, presumably because of the effects of these gene variants on risk of cerebral amyloid angiopathy. We aimed to assess whether these variants also associate with severity of ICH, in terms of haematoma volume at presentation and subsequent outcome. Methods We investigated the

A triangular form-based multiple flow algorithm to estimate overland flow distribution and accumulation on a digital elevation model

In this study, we present a newly developed method for the estimation of surface flow paths on a digital elevation model (DEM). The objective is to use a form-based algorithm, analyzing flow over single cells by dividing them into eight triangular facets and to estimate the surface flow paths on a raster DEM. For each cell on a gridded DEM, the triangular form-based multiple flow algorithm (TFM) w

A touch too much: Negotiating masculinity and proximity in intimate labor

This paper explores how men who perform intimate labour negotiate perceptions of themselves and their work through complex intersections of masculinity, proximity and propriety. Its focus is on the ways in which embodied organizational negotiations are shaped by gendered perceptions of bodily propriety in three examples of physically, sexually and/or emotionally intimate forms of labour: male mass

In vivo imaging of astrocytosis in Alzheimer's disease: an (11)C-L: -deuteriodeprenyl and PIB PET study.

PURPOSE: Astrocytosis is an important feature of the neuropathology of Alzheimer's disease (AD), yet there is currently no way of detecting this phenomenon in vivo. METHODS: In this study we examine the retention of the positron emission tomography (PET) tracer (11)C-L: -deuteriodeprenyl (DED), thought to bind activated astrocytes, in 9 patients with moderate to severe AD compared with 11 healthy

Converging Pathways of Chromogranin and Amyloid Metabolism in the Brain

Much is unknown regarding the regulation of Alzheimer-related amyloid-beta protein precursor (A beta PP)-processing in the human central nervous system. It has been hypothesized that amyloidogenic A beta PP-processing preferentially occurs in the regulated secretory pathway of neurons. To test this hypothesis we looked for correlations of A beta PP-derived molecules in cerebrospinal fluid (CSF) wi

Amplification and overexpression of the ABCC3 (MRP3) gene in primary breast cancer

The ATP-binding cassette (ABC) of active transporters comprises a group of proteins that which facilitate efflux of anticancer drugs from cancer cells. We focused on the gene amplification and protein expression of ABCC3 (also known as MRP3) in breast cancer cell lines and clinical tumor samples. Fluorescence and chromogenic in situ hybridization, using an ABCC3-specific probe, was used to analyze

Delineating Transcriptional Networks of Prognostic Gene Signatures Refines Treatment Recommendations for Lymph Node-negative Breast Cancer Patients.

The majority of women diagnosed with lymph node-negative breast cancer are unnecessarily treated with damaging chemotherapeutics following surgical resection. This highlights the importance of understanding and more accurately predicting patient prognosis. Here, we define the transcriptional networks regulating well-established prognostic gene expression signatures. We find that the same set of tr

Depression, Obesity and Smoking were Independently Associated with Inadequate Glycemic Control in Patients with Type 1 Diabetes.

OBJECTIVE: The aim of this study was to explore the associations between inadequate glycemic control of diabetes and psychological, anthropometric and life style variables in a population based cohort of type 1 diabetes patients. DESIGN: Cross-sectional study. METHODS: In this study 292 patients with type 1 diabetes participated, age 18-59 years. Psychological data were assessed by self-report ins

Coupled diffusion-deformation multiphase field model for elastoplastic materials applied to the growth of Cu6Sn5

A coupled diffusion-deformation, multiphase field model for elastoplastic materials is presented. The equations governing the evolution of the phase fields and the molar concentration field are derived in a thermodynamically consistent way using microforce balance laws. As an example of its capabilities, the model is used to study the growth of the intermetallic compound (IMC) Cu6Sn5 during room-t

Exposure to persistent organic pollutants and sperm sex chromosome ratio in men from the Faroe Islands.

People in the Arctic as well as fishermen on the polluted Swedish east coast are highly exposed to persistent organic pollutants (POPs). These compounds have been shown to affect the sperm Y:X chromosome ratio. In present study, the aim was to investigate whether polychlorinated biphenyl (PCB) congeners and 1,1,-dichloro-2,2,-bis(p-chlorophenyl)ethane (p,p'-DDE) influence sperm sex chromosome rati

Reduction of off-state drain leakage in InGaAs-based metal-oxide-semiconductor field-effect transistors

Off-state drain leakage current has been investigated for InGaAs-based metal-oxide-semiconductor field-effect transistors with different drain configurations, InGaAs, and InP, respectively. The introduction of an InP drain presents a lower leakage current compared to InGaAs drain devices. From temperature dependent measurements, the leakage current mechanisms have been differentiated, and the role

Biological applications of a new isothermal calorimeter that simultaneously measures at four temperatures

Isothermal calorimetry is a powerful technique for the study of kinetics of physical, chemical, and biological processes, for example, of their temperature dependence. A new heat conduction calorimeter that simultaneously makes measurements on four samples at four different temperatures is presented in this article. Results from tests with four biological systems (milk fermentation, carrot juice s

Wikipedia, heterotopi och versioner av kulturella minnen

The article draws together studies on encyclopaedic expressions throughout history with Foucault's notion of heterotopia, i.e. actually existing utopias or ‘other’, particular spaces that exist besides society's regular spaces and which work according to their own rules. It explores how we can understand contemporary online encyclopaedias, specifically Wikipedia, as digital heterotopias. For this

Subsequent Risks of Parkinson Disease in Patients with Autoimmune and Related Disorders: A Nationwide Epidemiological Study from Sweden.

Objectives: To investigate associations between autoimmune disorders and Parkinson disease (PD), and to study whether the risk is associated with follow-up time and age. Methods: Standardized incidence ratios (SIRs) were calculated for PD in patients with autoimmune disorders by comparing them to subjects without autoimmune disorders. Results: Among 310,522 patients with a total of 33 conditions o

U-Pb baddeleyite and zircon ages of 2040 Ma, 1650 Ma and 885 Ma on dolerites in the West African Craton (Anti-Atlas inliers): Possible links to break-up of Precambrian supercontinents

Precambrian inliers of the Anti-Atlas belt in the southern part of Morocco contain numerous dolerite dyke and sill swarms which were previously poorly dated. Four dykes and two sills dated by the U-Pb TIMS method on baddeleyite and zircon provide the first steps toward a magmatic 'barcode' for the West African Craton (WAC) and constraints on the timing of breakup of the WAC from Precambrian superc

An enormous amorphous silica stock in boreal wetlands

We investigated amorphous Si (ASi) in a boreal wetland in northern Sweden. We found enormous stocks of ASi in the upper soil layers (up to 11% of dry weight), in the form of diatom frustules and plant ASi. A consistent exponential decrease in ASi concentrations was observed with increasing depth in the soil profile. An inverse modeling approach shows that vegetation takes up a substantial part of
