Development of screening guidelines and clinical criteria for predementia Alzheimer's disease

Background: There is an urgent need to identify subjects with Alzheimer's disease (AD) in the predementia phase, but validated diagnostic approaches are currently lacking. In this paper, we present the background, design and methods of a study, which aims to develop clinical criteria for predementia AD. We also present baseline characteristics of the subjects included. The study was part of the mu

Horismenus species (Hymenoptera : Eulophidae) in a bruchid beetle parasitoid guild, including the description of a new species

Four species of Horismenus (Hymenoptera: Eulophidae) associated with Acanthoscelides spp. (Coleoptera: Bruchidae), three of which are also associated with Phaseolus spp., are treated. One of the species, H. butcheri, is described as new and the remaining three species are redescribed. All four species are diagnosed in a key. A lectotype is designated for Holcopelte productus Ashmead.

Reproducibility of Doppler measurements of blood flow velocity in the uterine and ovarian arteries in premenopausal women

Intra- and interobserver reproducibility of Doppler measurements of the pulsatility index (PI) and time-averaged maximum velocity (TAMXV) in the uterine and ovarian arteries were evaluated in examinations of healthy premenopausal women. Each woman underwent reproducibility measurements once in the late follicular phase and once in the midluteal phase. Intraobserver repeatability was assessed in ex

Nutritional Supplementation Decreases Hip Fracture-related Complications.

Protein energy malnutrition is an important determinant of clinical outcome in older patients after hip fracture, but the effectiveness of nutritional support programs in routine clinical practice is controversial. We performed a prospective, randomized, controlled clinical trial to determine if nutritional supplementation decreased fracture-related complications in a selection of otherwise health

Cost effectiveness of haemophilia treatment: a cross-national assessment.

The aim of this study was to assess the incremental cost effectiveness of on-demand versus prophylactic haemophilia therapy in Germany, Sweden, the United Kingdom and The Netherlands from the third-party payers' perspective. Using a decision tree model, the cost effectiveness of on-demand versus prophylactic therapy was analysed by extrapolating data from the European Haemophilia Economic Study to

Time scales of water dynamics at biological interfaces: peptides, proteins and cells

Water 2H and 17O spin relaxation is used to study water dynamics in the hydration layers of two small peptides, two globular proteins and in living cells of two microorganisms. The dynamical heterogeneity of hydration water is characterized by performing relaxation measurements over a wide temperature range, extending deeply into the supercooled regime, or by covering a wide frequency range. Prote

Offspring performance and the adaptive benefits of prolonged pregnancy: experimental tests in a viviparous lizard

Offspring locomotor performance has been shown to influence fitness related traits in a wide range of taxa. One potential mechanism by which viviparous animals can increase the performance (e.g. sprint speed) of their offspring is by prolonging pregnancy (beyond that required for complete development). However, to date studies examining this potentially important maternal effect have been largely

"Why Don't We Arm the Left?" Mao's Culpability for the Cultural Revolution's "Great Chaos" of 1967

This article sets out to describe and explain the events that led, in the summer of 1967, to political chaos and near civil war in many parts of China. It links the violence on the ground to statements and policies formulated at the highest levels of the CCP and sets out to show how and why Mao Zedong himself must bear direct personal responsibility for what stands out as one of the darkest chapte

Monte Carlo simulations of polyion-macroion complexes. 1. Equal absolute polyion and macroion charges

Intermolecular structures of complexes formed between a charged polymer and a spherical and oppositely charged macroion have been studied by employing the primitive model solved by Monte Carlo simulations. The strong-complex case involving a polyion and a macroion with equal absolute charges and without small ions was considered. The influence of the polyion flexibility with a bare persistence len

The effect of rosiglitazone on urine albumin excretion in patients with type 2 diabetes mellitus and hypertension

Background: Thiazolidinediones are antidiabetic agents that improve insulin sensitivity (IS). Accumulating data indicate that these agents provide beneficial effects beyond glycemic control, such as improvement in vascular function. The aim of this study was to determine the effect of rosiglitazone on urine albumin excretion (UAE) in patients with type 2 diabetes mellitus (DM) and hypertension. Me

Prewetting and layering in athermal polymer solutions

Coexistence conditions for prewetting and layering at a hard surface in additive hard sphere polymer solutions, where the solvent particles are smaller than the monomers, have been calculated by density functional methods. Various chain lengths and pressures have been investigated. An unexpected finding is that prewetting in these systems may proceed below the bulk critical pressure. We rationaliz

Glucose and insulin responses in healthy men to barley bread with different levels of (1 -> 3;1 -> 4)-beta-glucans; predictions using fluidity measurements of in vitro enzyme digests

Bread products with three different levels (35, 50 and 75%) of the (1 -> 3; 1 -> 4)-beta-glucan rich barley genotype Prowashonupana (PW), 50% common barley (CB) or 100% white wheat, were given as a breakfast meal to 10 men and their postprandial blood glucose and insulin responses were measured. In addition, the viscosity of (1 -> 3; 1 -> 4)-beta-glucans isolated from the pw flours was measured, a

Accountability of Networked Climate Governance. The Rise of Transnational Climate Partnerships

Public-private partnerships (PPP) have been advanced as a new tool of global governance, which can supply both effective and legitimate governance. In the context of recent debates on the democratic legitimacy of transnational governance, this paper focuses on accountability as a central component of legitimacy. The aim of this paper is to map transnational climate partnerships and evaluate their

Impact of plasma von Willebrand factor levels in the diagnosis of type 1 von Willebrand disease: results from a multicenter European study (MCMDM-1VWD)

Background: Presence of bleeding symptoms, inheritance and reduced von Willebrand factor (VWF) contribute to the diagnosis of type 1 von Willebrand disease (VWD). However, quantitative analysis of the importance of VWF antigen (VWF:Ag) and ristocetin cofactor activity (VWF:RCo) levels in the diagnosis is lacking. Objectives: To evaluate the relative contribution of VWF measurement to the diagnosis

Mechanical properties of lime-hemp concrete containing shives and fibres

The effect of using different binding agents in combination with hemp shives and fibres in Lime-Hemp Concrete (LHC) building material was examined. LHC is a light composite building material with building lime as binding agents and hemp (Cannabis sativa) as a renewable raw material from agriculture. Contemporary LHC only uses the woody core part of the hemp, the shive. However, using both hemp shi

Neonatal ACE inhibition in rats interferes with lung development.

The renin-angiotensin system (RAS) is developmentally up-regulated and it is essential for kidney development in several species. Given the fact that the rat lung undergoes postnatal development, the mammalian lung possesses the highest angiotensin-converting enzyme (ACE) levels and ACE activity increases during the first weeks postpartum, we tested the hypothesis that ACE inhibition influences po

Constitutive relations, dissipation and reciprocity for the Maxwell equations in the time domain

The main goal of this paper is to establish general constitutive relations for the electromagnetic fields EBAR, DBAR, BBAR, and HBAR in a time domain setting. The four basic assumptions of the medium are linearity, invariance to time translations, causality, and continuity. These four assumptions imply that the constitutive relations are convolutions of the Riemann-Stieltjes type. A review of the
