Accuracy of protein hydropathy predictions.

Hydropathy is a dominant force in protein folding. Sequence-based hydropathy predictions are widely used, without knowledge about their accuracy and reliability. We investigated the prediction accuracy of 56 hydropathy scales by correlating predicted values with the accessible surface area in known protein structures. Results for different amino acids vary greatly within each scale. We also invest

Selective protein expression within the CNS using hybrid lentivirus.

Lentiviral vectors offer many advantages within the central nervous system. They are capable of transfecting neurons and can be readily manipulated for selective expression. This chapter describes the production and use of lentiviruses to deliver GFP to the central nervous system.

Diversity of IgE-encoding transcripts in sinus mucosa of subjects diagnosed with non-allergic fungal eosinophilic sinusitis

Abstract in UndeterminedBackground The role of allergy in the aetiopathogenesis of chronic rhinosinusitis (CRS) remains controversial. For example, in some cases with sinus fungal infections allergy can be demonstrated by standard tests. In other cases, such signs can be absent despite elevated levels of IgE-positive cells in sinus tissue and the presence of IgE and eosinophils in the sinus mucous

Short-term results of a prospective randomized evaluator blinded multicenter study comparing TVT and TVT-Secur.

INTRODUCTION AND HYPOTHESIS: The aim of this prospective randomized multicenter study was to compare TVT (tension-free vaginal tape) with TVT-Secur in terms of efficacy and safety. METHODS: We set out to enrol 280 stress incontinent women with a half time interim analysis of short-term cure and a continuous registration of adverse events. Of 133 randomized women, 126 were operated and 123 (TVT n =

Active cooling in traumatic brain-injured patients: a questionable therapy?

Hypothermia is shown to be beneficial for the outcome after a transient global brain ischaemia through its neuroprotective effect. Whether this is also the case after focal ischaemia, such as following a severe traumatic brain injury (TBI), has been investigated in numerous studies, some of which have shown a tendency towards an improved outcome, whereas others have not been able to demonstrate an

Epigenetic chromatin states uniquely define the developmental plasticity of murine hematopoietic stem cells.

Heritable epigenetic signatures are proposed to serve as an important regulatory mechanism in lineage fate determination. To investigate this, we profiled chromatin modifications in murine hematopoietic stem cells, lineage restricted progenitors and CD4(+) T cells using modified genome-scale miniChIP technology. We show that genes involved in mature hematopoietic cell function associate with disti

Effects of the oral, direct factor Xa inhibitor rivaroxaban on commonly used coagulation assays.

Introduction: Rivaroxaban is an oral direct factor Xa inhibitor developed for prophylaxis and treatment of thromboembolic disorders. Laboratory monitoring is not necessary but the dose dependent effects on common reagents and assay procedures are largely unknown. Objectives: To investigate the effect of rivaroxaban on commonly used coagulation assays. Material and Methods: Rivaroxaban was added to

Glycoprotein 340 and sialic acid in minor-gland and whole saliva of children, adolescents, and adults.

Glycoprotein 340 (gp-340) is a bacterial-binding glycoprotein found in major-gland and minor-gland saliva. Sialic acid, a common terminal structure of salivary glycoproteins, interacts with microorganisms and host ligands, as well as with free radicals. This study investigated the contents of gp-340 and sialic acid in minor-gland saliva and whole saliva of children (3 yr of age), adolescents (14 y

Cancer of unknown primary is associated with diabetes.

The incidences of both type 1 diabetes (T1D) and T2D are increasing worldwide. T2D is associated with many cancers. However, no data are available on cancer of unknown primary (CUP), a relatively common, fatal cancer for which tobacco smoking is the only known risk factor. At diagnosis, CUP metastases are found in various organs, which has implications for prognosis. We carried out a nationwide st

Prospective study of pandysmaturation and adult mental disorder in high-risk and normal-risk offspring.

More than 50 years ago, Fish postulated that a special form of early abnormal neurodevelopment, "pandysmaturation", defined a priori as constituting retarded cranial development in the first year of life, combined with delay in early motor milestone attainment, was related to genetic risk for schizophrenia, and was associated with schizophrenia-spectrum disorders in young adulthood. Fish confirmed

Transition from HCCI to PPC : Investigation of the Effect of Different Injection Timing on Ignition and Combustion Characteristics in an Optical PPC Engine

The partially premixed combustion (PPC) concept is regarded as an intermediate process between the thoroughly mixed Homogeneous charge compression ignition (HCCI) combustion and compression ignition (CI) combustion. It's a combination of auto-ignition mode, a fuel-rich premixed combustion mode, and a diffusion combustion mode. The concept has both high efficiency and low soot emission due to low h

Spectral analysis of time domain induced polarization waveforms

Spectral induced polarization is a well-established geophysical method that can be measured in both time- and frequency domain. Time- and frequency domain methods are theoretically equivalent via the Fourier transform. However, data acquisition parameters such as the sampling frequency and pulse length affect the actual spectral content of real time domain waveforms. Comparative studies showing th

Optical Characterization of the Combustion Process inside a Large-Bore Dual-Fuel Two-Stroke Marine Engine by Using Multiple High-Speed Cameras

Dual-fuel engines for marine propulsion are gaining in importance due to operational and environmental benefits. Here the combustion in a dual-fuel marine engine operating on diesel and natural gas, is studied using a multiple high-speed camera arrangement. By recording the natural flame emission from three different directions the flame position inside the engine cylinder can be spatially mapped

Impact of Multiple Injection Strategies on Performance and Emissions of Methanol PPC under Low Load Operation

There is growing global interest in using renewable alcohols to reduce the greenhouse gases and the reliance on conventional fossil fuels. Recent studies show that methanol combined with partially premixed combustion provide clear performance and emission benefits compared to conventional diesel diffusion combustion. Nonetheless, high unburned hydrocarbon (HC) and carbon monoxide (CO) emissions ca

Experimental and Numerical Assessment of Active Pre-chamber Ignition in Heavy Duty Natural Gas Stationary Engine

Gas engines (fuelled with CNG, LNG or Biogas) for generation of power and heat are, to this date, taking up larger shares of the market with respect to diesel engines. In order to meet the limit imposed by the TA-Luft regulations on stationary engines, lean combustion represents a viable solution for achieving lower emissions as well as efficiency levels comparable with diesel engines. Leaner mixt

Photodynamic therapy dosimetry using multiexcitation multiemission wavelength : toward real-time prediction of treatment outcome

Evaluating the optical properties of biological tissues is needed to achieve accurate dosimetry during photodynamic therapy (PDT). Currently, accurate assessment of the photosensitizer (PS) concentration by fluorescence measurements during PDT is typically hindered by the lack of information about tissue optical properties. In the present work, a hand-held fiber-optic probe instrument monitoring f
