Greater reduction of platelet activation markers and platelet-monocyte aggregates by prasugrel compared to clopidogrel in stable coronary artery disease

Prasugrel, a novel P2Y(12) ADP-receptor antagonist, has been reported to achieve greater inhibition of platelet aggregation compared to clopidogrel as assessed by light transmission aggregometry. It was the objective of this study to investigate the effect of prasugrel on alternative markers of platelet activation in comparison to a high loading dose and the approved maintenance dose of clopidogre

Zinc Transporter 8 Autoantibodies and Their Association With SLC30A8 and HLA-DQ Genes Differ Between Immigrant and Swedish Patients With Newly Diagnosed Type 1 Diabetes in the Better Diabetes Diagnosis Study.

We examined whether zinc transporter-8 autoantibodies (ZnT8A; arginine ZnT8-RA, tryptophan ZnT8-WA, and glutamine ZnT8-QA variants) differed between immigrant and Swedish patients due to different polymorphisms of SLC30A8, HLA-DQ, or both. Newly diagnosed autoimmune (≥1 islet autoantibody) T1D type 1 diabetic patients (n = 2,964,

Therapeutic Effect of Blocking CXCR2 on Neutrophil Recruitment and Dextran Sodium Sulfate-Induced Colitis

Dextran sodium sulfate (DSS)-induced colitis in mice is characterized by polymorphonuclear neutrophil (PMN) infiltration into the colonic mucosa and lumen. The mechanism by which this occurs is unclear. To begin to understand the mechanism, we determined the role of the PMN chemokine receptor, CXCR2, in DSS-induced colitis by using CXCR2(-/-) mice or by neutralizing CXCR2. DSS was administered thr

Fine Mapping the Spatial Distribution and Concentration of Unlabeled Drugs within Tissue Micro-Compartments Using Imaging Mass Spectrometry

Readouts that define the physiological distributions of drugs in tissues are an unmet challenge and at best imprecise, but are needed in order to understand both the pharmacokinetic and pharmacodynamic properties associated with efficacy. Here we demonstrate that it is feasible to follow the in vivo transport of unlabeled drugs within specific organ and tissue compartments on a platform that appli

A method for reporting and classifying acute infectious diseases in a prospective study of young children: TEDDY

Background: Early childhood environmental exposures, possibly infections, may be responsible for triggering islet autoimmunity and progression to type 1 diabetes (T1D). The Environmental Determinants of Diabetes in the Young (TEDDY) follows children with increased HLA-related genetic risk for future T1D. TEDDY asks parents to prospectively record the child's infections using a diary book. The pres

Toward High-Power Klystrons With RF Power Conversion Efficiency on the Order of 90%

The increase in efficiency of RF power generation for future large accelerators is considered a high priority issue. The vast majority of the existing commercial high-power RF klystrons operates in the electronic efficiency range between 40% and 55%. Only a few klystrons available on the market are capable of operating with 65% efficiency or above. In this paper, a new method to achieve 90% RF pow

Interstitial laser thermotherapy (ILT) of breast cancer - Methodology and immunological responce

Interstitial laser thermotherapy (ILT) is an attractive form of local therapy against cancer because of its anti-tumor immune activity. The aim of this work was to evaluate ILT in breast cancer with respect to technique, changes in tissue immunocompetent cells and effect on prognosis. The method is dependent on accurate assessment of the tumor, and another aim was therefore to evaluate if MRI is b

Prostate cancer and neuroendocrine differentiation. Molecular aspects in prostate cancer development

Popular Abstract in Swedish Prostata cancer är Sveriges vanligaste cancerform. Många patienter med prostata cancer kan bli botade med kirurgi. I en del fall är kurativt syftande behandling inte möjlig. Dessa patienter behandlas då med hormonbehandling. Hormon behandling går ut på att hämma effekten av det maligna könshormonet, testosteron, som både den normala prostata körteln och tumörcellerna ärHormone refractory prostate cancer occurs when androgen-deprivation therapy (ADT) fails to stop the growth of prostate cancer for any longer. Recent studies point towards a role for neuroendocrine (NE) differentiation in the development of hormone refractory disease. It has been hypothesized that NE-differentiated malignant tumor cells survive during ADT and promote development of androgen-indepen

Reduced diversity in the early fecal microbiota of infants developing atopic eczema

Background It might be that early intestinal colonization by bacteria in westernized infants fails to give rise to sufficient immune stimulation to support maturation of regulatory immune mechanisms. Objective The purpose of the present study was to characterize the very early infantile microbiota by using a culture-independent approach and to relate the colonization pattern to development of at

Are collagenous and lymphocytic colitis different aspects of the same disease?

Objective. Collagenous colitis (CC) and lymphocytic colitis (LC) are two subtypes of microscopic colitis (MC). Even though they most often are described as different entities they share many clinical and histological features. The aim of this study was to investigate the occurrence of conversion between CC and LC in a larger cohort of patients. Materials and methods. All 664 patients in our Pathol

A 28 GHz SiGe PLL for an 81-86 GHz E-band beam steering transmitter plus an I/Q phase imbalance detection and compensation circuit

This paper presents two circuits, a complete 1.5 V 28 GHz SiGe beam steering PLL and a standalone 28 GHz QVCO with I/Q phase imbalance detection and compensation. The circuits were designed in a SiGe process with f T = 200 GHz. The PLL is intended to be used for beam steering in an 81–86 GHz E-band transmitter. Phase control is implemented by DC current injection at the output of a Gilbert archite

Electrochemical behavior and application of Prussian blue nanoparticle modified graphite electrode

Prussian blue nanoparticles (PBNPs) were immobilized on the surface of a graphite electrode (GE) through a simple adsorption route and then the modified surface was covered with a layer of Nafion. The electrochemical behavior of the resulting sensor was investigated using cyclic voltammetry and chronoamperometry. The sensor showed good electrocatalytic activity toward hydrogen peroxide reduction,

Topical nasal steroid treatment does not improve CPAP compliance in unselected patients with OSAS

Background: Continuous positive airways pressure (CPAP) for treatment of obstructive sleep apnea (OSA) can produce troublesome nasal symptoms (i.e. congestion, rhinorrhea) that may reduce the compliance of CPAP. Topical nasal steroids are often prescribed to reduce these side effects, although scientific data are scarce supporting any benefits of this treatment for CPAP-induced nasal side effects.

Democracy and State Capacity: Exploring a J-shaped Relationship

In this article we probe the effect of democratization on the state's administrative capacity. Using time-series cross-section data, we find a curvilinear (J-shaped) relationship between the two traits. The effect of democracy on state capacity is negative at low values of democracy, nonexistent at median values, and strongly positive at high democracy levels. This is confirmed under demanding sta

Consumption of Dairy Products and Colorectal Cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC)

Background: Prospective studies have consistently reported lower colorectal cancer risks associated with higher intakes of total dairy products, total milk and dietary calcium. However, less is known about whether the inverse associations vary for individual dairy products with differing fat contents. Materials and Methods: In the European Prospective Investigation into Cancer and Nutrition (EPIC)
