The prognostic value of albuminuria for the development of cardiovascular disease and retinopathy: a 5-year follow-up of 451 patients with type 2 diabetes mellitus

The aim of the present study was to evaluate the risk for vascular morbidity or death and retinopathy in relation to urinary albumin concentration. To that end, we performed a 5-year follow-up study of all type 2 diabetic patients attending the outpatient-clinic. A total of 444 (98.4%) out of 451 adult patients initially studied were evaluated for the degree of retinopathy and levels of HbA1c bloo

Socioeconomic positoon and the risk of gastric and overphageal cancer in the European Prospective into Cancer and Nutrition (EPIC-EURGAST)

Objectives To evaluate the association of socioeconomic position with adenocarcinoma of the oesophagus and stomach. Methods The European Prospective Investigation into Cancer and Nutrition (EPIC) cohort comprises about 520000 participants mostly aged 35-70 years. Information on diet and lifestyle was collected at recruitment. After an average follow-up of 6.5 years, 268 cases with adenocarcinoma o

An academic ECG core lab perspective of the FDA initiative for digital ECG capture and data management in large-scale clinical trials

Maximal utility of accessible data is attractive to all partners in clinical research, whether it directly improves patient care or more accurately allows identification of the safety and efficacy of a new drug or procedure. The Food and Drug Administration (FDA) has presented a guideline draft addressing digitization of electrocardiogram (ECG) data in clinical trials to improve the standards for

Trace elements in blood and serum of Swedish adolescents: Relation to gender, age, residential area, and socioeconomic status

The influence of gender, age, residential area, and socioeconomic status on the blood and serum levels of 13 trace elements was studied in boys and girls living in two Swedish cities with different socioeconomic and environmental characters. The same groups of adolescents were sampled twice, at ages 15 (n = 372) and 17 (n = 294) years. All the investigated factors were shown to be of importance. A

Is there a relationship between balance, gait performance and muscular strength in 75-year-old women?

OBJECTIVE: To see if there is a relationship between clinical and laboratory tests of balance, muscular strength and gait in elderly women. DESIGN: A randomized population-based study. SETTINGS: Malmo, Sweden. METHODS: We investigated balance with a simple test of standing on one leg, as well as a computerized balance platform. Muscular strength was tested by computerized dynamometer. Extension an

The Chloroplast Small Heat Shock Protein-Purification and Characterization of Pea Recombinant Protein

We report here on a procedure to obtain large amounts of a chloroplast-localized heat shock protein (HSP21) with unknown structure and function, by using anEscherichia coliexpression system for the pea (Pisum sativum) protein and a purification procedure based on perfusion ion-exchange chromatography. After initial precipitation steps, the sample was applied to cation- and anion-exchange on two co

Effect of metal-rich sludge amendments on the soil microbial community

The effects of heavy-metal-containing sewage sludge on the soil microbial community were studied in two agricultural soils of different textures, which had been contaminated separately with three predominantly single metals (Cu, Zn, and Ni) at two different levels more than 20 years ago. We compared three community-based microbiological measurements, namely, phospholipid fatty acid (PLFA) analysis

Transcending Tradition : Towards a Critical Theology of the Spirit

In recent years, the renewed presence of religion in the European societies has inspired a number of intellectuals on a popular as well as academic level to critically engage with religion. The aim of this article is to give a contribution to this debate. In contrast to the rather reductive and objectifying accounts of religion offered in much of the contemporary critique, I argue that a relevant

Theoretical interpretation of impulse response tests of embedded concrete structures

For a concrete beam resting on a bed of sand, an analytical solution technique is derived by which the mobility can be identified. To achieve realistic predictions, significant damping in the bed needs to be introduced. The modest damping of the concrete has little effect on the mobility for small frequencies whereas it has a significant effect for higher frequencies. An imperfection in the bed in

Parental perspectives on preterm children's oral health behaviour and experience of dental care during preschool and early school years

Background. Children born preterm (PT) have medical conditions and impairments that may affect their oral health. Hypothesis. Our hypothesis for the study was that PT children display more dental behaviour management problems (BMPs) and less favourable oral health behaviour than controls (C). Methods. Parents of 153 PT children and 153 C children were interviewed regarding the children's oral heal

Genomewide linkage analysis of stature in multiple populations reveals several regions with evidence of linkage to adult height

Genomewide linkage analysis has been extremely successful at identification of the genetic variation underlying single-gene disorders. However, linkage analysis has been less successful for common human diseases and other complex traits in which multiple genetic and environmental factors interact to influence disease risk. We hypothesized that a highly heritable complex trait, in which the contrib

Methods for the detection and analysis of protein-protein interactions

A large number of methods have been developed over the years to study protein-protein interactions. Many of these techniques are now available to the nonspecialist researcher thanks to new affordable instruments and/or resource centres. A typical protein-protein interaction study usually starts with an initial screen for novel binding partners. We start this review by describing three techniques t

Chemical and Thermal Unfolding of Glypican-1: Protective Effect of Heparan Sulfate against Heat-Induced Irreversible Aggregation

Glypicans are cell-surface heparan sulfate proteoglycans that influence Wnt, hedgehog, decapentaplegic, and fibroblast growth factor activity via their heparan sulfate chains. However, recent studies have shown that glypican core proteins also have a role in growth factor signaling. Here, we expressed secreted recombinant human glypican-1 in eukaryotic cells. Recombinant glypican-1 was expressed a

Importance of protein S and phospholipid for activated protein C-mediated cleavages in factor Va.

The procoagulant function of activated factor V (FVa) is inhibited by activated protein C (APC) through proteolytic cleavages at Arg(306), Arg(506), and Arg(679). The effect of APC is potentiated by negatively charged phospholipid membranes and the APC cofactor protein S. Protein S has been reported to selectively stimulate cleavage at Arg(306), an effect hypothesized to be related to reorientatio

Carrying large fuel loads during sustained bird flight is cheaper than expected

Birds on migration alternate between consuming fuel stores during flights and accumulating fuel stores during stopovers. The optimal timing and length of flights and stopovers for successful migration depend heavily on the extra metabolic power input (fuel use) required to carry the fuel stores during flight(1,2). The effect of large fuel loads on metabolic power input has never been empirically d

Simulations and density functional calculations of surface forces in the presence of semiflexible polymers

We simulate interactions between adsorbing and nonadsorbing surfaces immersed in solutions containing monodisperse semiflexible chains. Apart from the nature of the surfaces, we investigate responses to changes of the intrinsic chain stiffness, the degree of polymerization, and the bulk concentration. Our simulations display a sufficient accuracy and precision to reveal free-energy barriers that a
