PACSIN 1 forms tetramers via its N-terminal F-BAR domain

The ability of protein kinase C and casein kinase 2 substrate in neurons (PACSIN)/syndapin proteins to self-polymerize is crucial for the simultaneous interactions with more than one Src homology 3 domain-binding partner or with lipid membranes. The assembly of this network has profound effects on the neural Wiskott-Aldrich syndrome protein-mediated attachment of the actin polymerization machinery

T-Helper 2 Immunity Is Associated With Reduced Risk of Myocardial Infarction and Stroke.

OBJECTIVE: Experimental studies in mice have attributed T-helper (Th) 1 and Th2 cells important roles in atherosclerosis, but the clinical importance of these cells in cardiovascular disease (CVD) remains to be clarified. Here, we investigated associations between Th1 and Th2 cells, carotid intima-media thickness, and cardiovascular risk. METHODS AND RESULTS: Blood drawn at baseline and incident c

Kinematic wave modelling of saturated basal flow in a snowpack

Movement of snowmelt water through a thin saturated layer at the infiltrating base of a snowpack is modelled by applying the kinematic wave theory. Analytical solutions are obtained for flow depth, velocity and discharge assuming that the rate of input to the saturated layer due to vertical percolation is constant. This assumption results in a linear rise and recession of the snowmelt hydrograph.

Importance of rapid bleeding control in haemophilia complicated by inhibitors.

Summary. Despite improvements in therapy that has greatly enhanced the treatment of patients with haemophilia with inhibitors, they are still at risk of poorer outcomes including haemophilic arthropathy and long-term disability. The objective of this review is to consider clinical data on the effect of rapid control of bleeding episodes on outcomes in these patients. Rapid control of bleeding epis

Non-optimal focusing of ultrasound does not affect dual frequency ultrasound measurements

In pulse-echo (PE) ultrasound measurements, the use of focused transducers is desirable for quantitative assessment of bone characteristics because of the attenuation in the overlying soft tissues. However, the variable thickness and composition of the soft tissue overlying bone affect the focal depth of the ultrasound beam and induce errors into the measurements. To compensate for the attenuation

Disease-associated patterns of disomic chromosomes in hyperhaploid neoplasms.

The chromosome number of human tumors varies widely, from near-haploidy to more than decaploidy. Overt hyperhaploid (24-34 chromosomes) tumors constitute a small minority (0.2-0.3% of cytogenetically investigated lesions), but occur in many different disease entities. In these karyotypes, most chromosomes are present in one copy; one or a few chromosomes are disomic. Published reports on 141 stric

Food sources of fat and sex hormone receptor status of invasive breast tumors in women of the malmö diet and cancer cohort.

We examined associations between food intakes and incident breast cancer, defined by estrogen receptor (ER) and progesterone receptor (PR) status in the Malmö Diet and Cancer cohort (17,000 women aged 45-73 yr). The hazard ratios (HRs) of ER+PR+ (n = 270), ER+PR- (n = 87), and ER-PR- (n = 61) tumors and all cancer (n = 544) were estimated after 10 yr of follow-up. In multivariate analysis of ER+PR

Success Story of Targeted Therapy in Chronic Myeloid Leukemia: A Population-Based Study of Patients Diagnosed in Sweden From 1973 to 2008.

PURPOSE Chronic myeloid leukemia (CML) management changed dramatically with the development of imatinib mesylate (IM), the first tyrosine kinase inhibitor targeting the BCR-ABL1 oncoprotein. In Sweden, the drug was approved in November 2001. We report relative survival (RS) of patients with CML diagnosed during a 36-year period. PATIENTS AND METHODS Using data from the population-based Swedish Can

Bile retinoids imprint intestinal CD103(+) dendritic cells with the ability to generate gut-tropic T cells.

Small intestinal lamina propria (SI-LP) CD103(+) dendritic cells (DCs) are imprinted with an ability to metabolize vitamin A (retinol), a property underlying their enhanced capacity to induce the gut-homing receptors CC chemokine receptor-9 and α4β7 on responding T cells. In this study, we demonstrate that imprinting of CD103(+) DCs is itself critically dependent on vitamin A and occurs locally wi

A randomized, multicentre, double-blind, parallel-group study to assess the adverse event-related discontinuation rate with celecoxib and diclofenac in elderly patients with osteoarthritis.

Objective: To compare the adverse event (AE)-related discontinuation rate with celecoxib vs. diclofenac when given to reduce joint pain associated with knee or hip osteoarthritis (OA) in elderly patients. Methods: This was a double-blind, randomized, multicentre, parallel-group, 1-year comparison of celecoxib 200 mg once daily and diclofenac 50 mg twice daily in 925 patients with OA aged >/= 60 ye

Simulation of Multibody Systems by a Parallel Extrapolation Method

In the simulation of multibody systems, the equations of motion are generated by so-called multibody formalisms as a system of differential-algebraic equations (DAEs). A recently developed extrapolation method for integrating the equations of motion is investigated. Extrapolation methods for ordinary differential equations are briefly reviewed, before proceeding to the DAE method. The inherent par

A conceptual fatigue-motivation model to represent pedestrian movement during stair evacuation

Evacuation models often neglect the impact of fatigue on pedestrian movement during stair evacuation. While a limited number of sub-models are available in the literature to represent fatigue during evacuations, they mostly refer to simple, fixed walking speed reductions due to physical fatigue. This paper introduces a more comprehensive conceptual model for the representation of the impact of fat

Medical Diagnostic System Based On Simultaneous Multispectral Fluorescence Imaging

A multicolor fluorescence imaging system applied to medical diagnostics is described. The system presented simultaneously records four fluorescence images in different wavelength bands, permitting low-resolution spectroscopy imaging. An arithmetic function image of the four spectral images is constructed by a pixel-to-pixel calculation and is presented on a monitor in false-color coding. A sensiti

Strategy for identification and detection of multiple oxidative modifications within proteins applied on persulfate-oxidized hemoglobin and human serum albumin.

Oxidative stress has been suggested as an underlying mechanism of many human diseases. However, definitive evidence for this association has not been presented due to different shortcomings of the methods used to measure biomarkers of oxidative stress. Persulfates are oxidizing agents known to elicit hypersensitive reactions from the airways and skin. Despite a frequent use of persulfates at many

Pregnancy and the methyltransferase genotype independently influence the arsenic methylation phenotype.

OBJECTIVES: The methyltransferase genotype and pregnancy both influence the arsenic metabolism phenotype, but it is unknown whether these factors interact, explaining the drastic changes in the efficiency of arsenic metabolism observed among pregnant women. The aim of this study was to evaluate the relative contribution of the methyltransferase genotype and pregnancy to the arsenic metabolism phe

Increased expression of vascular endothelial growth factor-a in seasonal allergic rhinitis

Increased vascular dilatation and permeability characterize allergic rhinitis. In this study oligonucleotide microarrays (Affymetrix HuGe95A) were used to identify differentially expressed vasoactive genes in nasal biopsies from 23 patients with symptomatic seasonal allergic rhinitis (SAR) and 12 healthy controls. RNA was extracted from the biopsies and pooled in three patient and three control po
