Preparation of Films of a Highly Aligned Lipid Cubic Phase

We demonstrate a method by which we can produce an oriented film of an inverse bicontinuous cubic phase (QII,D) formed by the lipid monoolein (MO). By starting with the lipid as a disordered precursor (the L3 phase) in the presence of butanediol, we can obtain a film of the QII,D phase showing a high degree of in-plane orientation by controlled dilution of the sample under shear within a linear fl

Albumin-induced coagulopathy is less severe and more effectively reversed with fibrinogen concentrate than is synthetic colloid-induced coagulopathy.

Background. Synthetic colloids cause dilutional coagulopathy. The aims of our study were to determine whether the natural colloid albumin induces a lesser degree of coagulopathy compared to synthetic colloids, and the comparative effectiveness of fibrinogen concentrate to reverse coagulopathy following dilution with these solutions. Methods. Coagulation was assessed with rotational thrombelastomet

Patient-reported recovery after enhanced colorectal cancer surgery: a longitudinal six-month follow-up study.

The concept of enhanced recovery after surgery (ERAS) is a modern regime of care, and numerous studies have proved its beneficial impact on recovery after colorectal surgery. However, little is known about patients' continuing recovery after discharge. Therefore, the purpose of this study was to describe patient-reported recovery after colorectal cancer surgery in the context of ERAS from the day

Modulating mGluR5 and 5-HT1A/1B receptors to treat l-DOPA-induced dyskinesia: Effects of combined treatment and possible mechanisms of action.

l-DOPA-induced dyskinesia (LID) is a major complication of the pharmacotherapy of Parkinson's disease. Emerging approaches to the treatment of LID include negative modulation of metabotropic glutamate receptor type 5 (mGluR5) and positive modulation of serotonin receptors 5-HT1A/1B. We set out to compare the efficacy of these two approaches in alleviating the dyskinesias induced by either l-DOPA o

Assessing the effect of the time since transition to organic farming on plants and butterflies

P>1. Environmental changes may not always result in rapid changes in species distributions, abundances or diversity. In order to estimate the effects of, for example, land-use changes caused by agri-environment schemes (AES) on biodiversity and ecosystem services, information on the time-lag between the application of the scheme and the responses of organisms is essential. 2. We examined the effec

Pilgrimstad revisited - a multi-proxy reconstruction of Early/Middle Weichselian climate and environment at a key site in central Sweden

The site Pilgrimstad in central Sweden has often been cited as a key locality for discussions of ice-free/ice-covered intervals during the Early and Middle Weichselian. Multi-proxy investigations of a recently excavated section at Pilgrimstad now provide a revised picture of the climatic and environmental development between similar to 80 and 36 ka ago. The combination of sedimentology, geochemist

Colloidal gelation with variable attraction energy

We present an approximation scheme to the master kinetic equations for aggregation and gelation with thermal breakup in colloidal systems with variable attraction energy. With the cluster fractal dimension d(f) as the only phenomenological parameter, rich physical behavior is predicted. The viscosity, the gelation time, and the cluster size are predicted in closed form analytically as a function o

A Four-Kallikrein Panel Predicts Prostate Cancer in Men with Recent Screening: Data from the European Randomized Study of Screening for Prostate Cancer, Rotterdam

Purpose: We have developed a statistical prediction model for prostate cancer based on four kallikrein markers in blood: total, free, and intact prostate-specific antigen ( PSA), and kallikrein-related peptidase 2 ( hK2). Although this model accurately predicts the result of biopsy in unscreened men, its properties for men with a history of PSA screening have not been fully characterized. Experime

Synthesis of water-dispersible photoluminescent silicon nanoparticles and their use in biological fluorescent imaging

Water-dispersible silicon nanoparticles (Si-NPs) are desirable for applications in biological techniques. A simplified method to synthesize such particles is reported here. The resulting Si-NPs are water-dispersible and luminescent. Under the excitation of UV light, the Si-NPs emit strong red light with a peak maximum at 606 nm and a quantum yield of 6%. They are highly stable, and remain so over

Pump-Flow-Probe X-ray Absorption Spectroscopy as a Tool for Studying Intermediate States of Photocatalytic Systems

A new setup for pump-flow-probe X-ray absorption spectroscopy has been implemented at the SuperXAS beamline of the Swiss Light Source. It allows recording X-ray absorption spectra with a time resolution of tens of microseconds and high detection efficiency for samples with sub-millimolar concentrations. A continuous wave laser is used for the photoexcitation, with the distance between laser and X-

Capacitive immunosensor for the detection of host cell proteins.

A new analysis for monitoring host cell proteins in preparations of transgenically produced protein pharmaceuticals is described. A capacitive biosensor with a very high sensitivity is used to monitor trace amounts of host cell proteins. The sensor consists of a gold electrode, the surface of which is well insulated and on which a preparation of a population of polyclonal antibodies raised against

International consensus criteria for the diagnosis of Raynaud's phenomenon.

Vasoconstriction accompanied by changes in skin color is a normal physiologic response to cold. The distinction between this normal physiology and Raynaud's phenomenon (RP) has yet to be well characterized. In anticipation of the 9th International Congress on Autoimmunity, a panel of 12 RP experts from 9 different institutes and four different countries were assembled for a Delphi exercise to esta

When and where does mortality occur in migratory birds? Direct evidence from long-term satellite tracking of raptors.

Information about when and where animals die is important to understand population regulation. In migratory animals, mortality might occur not only during the stationary periods (e.g. breeding and wintering) but also during the migration seasons. However, the relative importance of population limiting factors during different periods of the year remains poorly understood, and previous studies main

IGHV3-21 Gene Frequency in a Swedish Cohort of Patients With Newly Diagnosed Chronic Lymphocytic Leukemia

The IGHV3-21 gene has been shown to be overrepresented in Scandinavian patients with chronic lymphocytic leukemia (CLL). By investigating a population-based cohort of 337 Swedish patients with CLL, a lower (6.5%) IGHV3-21 frequency was determined relative to our previous hospital-based studies (10.1%-12.7%), yet this frequency remained higher compared to other Western CLL cohorts (2.6%-4.1%). Furt

Herbivory and dominance shifts among exotic and congeneric native plant species during plant community establishment.

Invasive exotic plant species often have fewer natural enemies and suffer less damage from herbivores in their new range than genetically or functionally related species that are native to that area. Although we might expect that having fewer enemies would promote the invasiveness of the introduced exotic plant species due to reduced enemy exposure, few studies have actually analyzed the ecologica

Acquisition cost of dispensed drugs in individuals with multiple medications A register-based study in Sweden

Objectives: To analyse the acquisition cost of dispensed prescription drugs for individuals with multiple medications in a national population. Methods: We collected and analysed individual based data regarding the acquisition cost of dispensed prescription drugs for all individuals with five or more dispensed drugs (DP >= 5) in Sweden 2006 (2.2 million). Results: Individuals with DP >= 5 (24.5% o

Ventricular repolarization sequences on the epicardium and endocardium. Monophasic action potential mapping in healthy pigs

To investigate repolarization sequence, monophasic action potentials were recorded from a mean of 153 +/- 54 left and right ventricular epicardial and endocardial sites in 10 pigs using the CARTO mapping system (Biosense Webster, Waterloo, Belgium). The activation time and end-of-repolarization (EOR) time were measured and 3-dimensional maps of activation and repolarization sequences constructed.

Impact of Periodontal Disease Experience on Oral Health-Related Quality of Life

Background: Periodontal research has traditionally focused on the site level, regarding etiology, pathogenesis, and treatment outcome. Recently, some studies have indicated that the presence of periodontal disease is associated with reduced quality of life. The aim of this study is to investigate the impact of periodontal disease experience on the quality of life. Methods: This cross-sectional stu

Non-intrusive measurements of headspace gas composition in liquid food packages made of translucent materials

The increase in chilled food consumption requires enhanced food safety and quality assurance. Food deteriorating processes are affected by the presence of oxygen, combined with factors such as time and temperature. To slow down deterioration processes and prolong shelf life, traditional packaging methods are being replaced by Modified Atmosphere Packaging (MAP), for example. Oxygen, which is natur
