The N-terminal EGF domain of coagulation factor IX: Probing its functions in the activation of factor IX and factor X with a monoclonal antibody.

SUMMARY Absence or reduced activity of coagulation factor IX (FIX) causes the severe bleeding disorder hemophilia B. FIX contains an N-terminal Gla domain followed by two epidermal growth factor (EGF)-like domains and a serine protease domain. In this study the epitope of monoclonal antibody AW, which is directed against the C-terminal part of the first EGF domain in human FIX, was defined and the

Automatic measurement of atrial pacing thresholds in dual-chamber pacemakers: Clinical experience with atrial capture management

BACKGROUND The Medtronic EnPulse (TM) pacemaker incorporates the new atrial capture management (ACM) algorithm to automatically measure atrial capture thresholds and subsequently manage atrial pacing outputs. OBJECTIVES The purpose of this study was to evaluate the clinical performance of ACM. METHODS Two hundred patients with an indication for a dual-chamber pacemaker underwent implantation. ACM

Variability of patch type preferences in relation to resource availability and breeding success in a bird

This paper investigates how variability in partial foraging preferences for patch types can be used as a behavioral indicator of the energetic value of that patch type, and of overall food availability in the territory. The species studied was the lesser spotted woodpecker (Dendrocopos minor) and the patch types it uses are four groups of tree species (oak Quercus robur, birch Betula pendula, B. p

Diffusion of glucose and insulin in a swelling N-isopropylacrylamide gel

The diffusional characteristics for poly(N-isopropylacrylamide) (NiPAAm) gel have been investigated. This gel is a critical gel which means that small changes in the environment influence the gel volume considerably. The effective diffusion coefficients for the solutes glucose and insulin were determined in batch experiments with the solutes diffusing out from small cylindrical gel bodies with dia

Investigation of a 31% Charged Cationic Polyelectrolyte Interacting with Sodium Dodecylsulfate in Bulk Solution and as a Preadsorbed Layer on Mica. Low Ionic Strength

The behavior of mixtures of a cationic polyelectrolyte of intermediate charge density (31%) and anionic surfactant both in bulk and at a negatively charged solid surface has been investigated. The polyelectrolyte employed was a random copolymer of the neutral acrylamide and cationic [3-(2-methylpropionamido)propyl]trimethylammonium chloride, and the surfactant was sodium dodecyl sulfate (SDS). Mea

First-line treatment of ovarian cancer FIGO stages IIb-IV with paclitaxel/epirubicin/carboplatin versus paclitaxel/carboplatin

The objective of this study was to compare the safety and efficacy of carboplatin plus epirubicin and paclitaxel (TEC) to carboplatin and paclitaxel (TC), in the treatment of epithelial ovarian, peritoneal, or tubal carcinoma.. Between March 1999 and August 2001, 887 patients were randomized to receive six to nine cycles of paclitaxel (175 mg/m(2), 3 h intravenously) followed by carboplatin (AUC 5

Serum cystatin C, determined by a rapid, automated particle-enhanced turbidimetric method, is a better marker than serum creatinine for glomerular filtration rate

We describe a fully automated particle-enhanced turbidimetric assay for cystatin C in undiluted serum and EDTA-plasma. The throughput is 90 samples per hour and urgent samples can be analyzed in 7 min. The assay range (0.4-14.1 mg/L) covers the concentration range in health and disease. The within- and between-run imprecision is 0.9% and 2.2%, respectively. Analytical recovery of additions of reco

Reducing Asymmetries in Intergenerational Justice: Descent from Modernity or Space Industrialization?

Normally, contractual conceptions of intergenerational justice regard the responsibility held by each generation as symmetrical. This article argues that the late modern society has created an asymmetry because of its unprecendented instrumental and destructive capacity. Historically unique risks such as thermonuclear destruction, global ecological deprivation, and resource depletion all point at

Mapping of quick clay formations using geotechnical and geophysical methods

Quick clay has been involved in most serious, large clay slides in Sweden, Norway, and Canada. This paper describes geotechnical and geophysical methods that can be used to locate and map the extent of quick clay formations. Surface resistivity measurements and four different sounding methods have been tested. The results have been compared with sensitivities determined using fall-cone tests. The

Long-term efficacy of early versus delayed radiotherapy for low-grade astrocytoma and oligodendroglioma in adults: the EORTC 22845 randomised trial

Background Postoperative policies of "wait-and-see" and radiotherapy for low-grade glioma are poorly defined. A trial in the mid 1980s established the radiation dose. In 1986 the EORTC Radiotherapy and Brain Tumor Groups initiated a prospective trial to compare early radiotherapy with delayed radiotherapy. An interim analysis has been reported. We now present the long-term results. Methods After s

A physically motivated modification of the strain equivalence approach

A phenomenological thermodynamic approach used for describing elasto-plasticity coupled with isotropic damage is considered. Using this approach it was recently shown by the authors that certain unwanted features exist in the plasticity-induced damage theories. This paper gives a suggestion on how to solve these issues. Based on physical arguments a simple modification of the postulate of strain e

Antibody-based microarrays.

Antibody-based microarrays are a new powerful proteomic technology that can be used to generate rapid and detailed expression profiles of defined sets of protein analytes in complex samples as well as high-resolution portraits of entire proteomes. Miniaturized micro- and nanoarrays can be printed with numerous antibodies carrying the desired specificities. Multiplexed and ultra-sensitive assays, s

Is private consumption growth higher (lower) during periods of fiscal contractions (expansions)?

Case studies have claimed that private consumption growth is higher during fiscal contractions due to the very fact that government spending is cut. Indeed, neoclassical theory has this implication. This paper uses regression analysis of a panel of 19 OECD countries and shows that this is not true in general. On the contrary, contraction (expansion) periods experience lower (higher) private consum

Metal ion enhanced binding of amd3100 to asp-262 in the cxcr4 receptor.

The affinity of AMD3100, a symmetrical nonpeptide antagonist composed of two 1,4,8,11-tetraazacyclotetradecane (cyclam) rings connected through a 1,4-dimethylene(phenylene) linker to the CXCR4 chemokine receptor was increased 7, 36, and 50-fold, respectively, by incorporation of the following: Cu2+, Zn2+, or Ni2+ into the cyclam rings of the compound. The rank order of the transition metal ions co

Simulating vegetation cover dynamics with regards to long-term climatic variations in sub-arctic landscapes

Iceland is facing severe land degradation in many parts of the country. This study aims to increase the understanding of the complex interactions and interconnectivity between the critical factors that help maintain the land degradation processes in sub-arctic environments. A holistic approach in the form of a causal loop diagram (CLD) is applied for diagnosing the influencing factors. To further

The illness experiences of patients after a first time myocardial infarction

The purpose of this study was to investigate illness experiences of patients after a first myocardial infarction (MI), focusing on life situation and the recovery process over time. Thirty patients were interviewed within the first 3 days of hospitalisation, and again 17 weeks after discharge. The interviews were tape-recorded verbatim and the transcriptions were analysed and categorised using qua

Ordovician palaeogeography with new palaeomagnetic data from the Montagne Noire (Southern France)

A joint palaeomagnetic and Ar-40/Ar-39 study has been performed on two olistolithic blocks from the Cabrieres Wildflysch in the Montagne Noire region of the Massif Central in France. There, andesitic volcanic and volcaniclastic rocks of Llanvirn-Early Caradoc age (ca 470-458 Ma) occur. Despite extensive secondary alteration, destruction of the dominant magnetic mineral phase and Ar-40/Ar-39 whole
