Fasting insulin has a stronger association with an adverse cardiometabolic risk profile than insulin resistance: the RISC study

Objective: Fasting insulin concentrations are often used as a surrogate measure or insulin resistance. We investigated the relative contributions Of fasting insulin and insulin resistance to cardiometabolic risk and preclinical atherosclerosis. Design and methods: The Relationship between Insulin Sensitivity and Cardiovascular disease (RISC) cohort consists of 1326 European non-diabetic. overall h

Secondary prophylaxis with recombinant activated factor VII improves health-related quality of life of haemophilia patients with inhibitors

Haemophilia patients with inhibitors characteristically have impaired joint function and reduced health-related quality of life (HRQoL). This analysis examined whether secondary prophylaxis with recombinant activated factor VII (rFVIIa) improves HRQoL vs. conventional on-demand therapy in patients with haemophilia with inhibitors and frequent bleeds. After a 3-month preprophylaxis period, 22 patie

Temporal and spatial patterns of repeated migratory journeys by ospreys

We used satellite-tracking data from repeated journeys between Europe and West Africa by the same osprey, Pandion haliaetus, individuals to test whether the timing of migration differs between spring and autumn and whether landmarks and stopover goal areas are important for navigation. The timing of migration varied more in autumn than in spring, owing to significant differences between individual

The international cooperative test of the critical degree of saturation method of assessing the freeze/thaw resistance of concrete

The article describes the execution and result of an investigation of the "'ScR-method'" of freeze/thaw-testing concrete. The investigation formed part of the work within RILEM Committee 4-CDC. Five laboratories participated. Two concrete types were tested," one without and one with entrained air. At each laboratory the critical degree of saturation, SCR, was determined by freeze/thaw-experiments

Modulation of invasive properties of murine squamous carcinoma cells by heterologous expression of cathepsin B and cystatin C

Murine SCC-VII squamous carcinoma cells have the capacity to penetrate reconstituted basement membranes (Matrigel) in vitro. The invasion of Matrigel layers by SCC-VII cells was significantly reduced by E-64, a specific inhibitor of lysosomal cysteine proteinases. The cathepsin-B-selective E-64 derivative, CA-074, inhibited penetration of Matrigel by SCC-VII cells to the same extent, indicating a

A high throughput procedure for polycyclic aromatic hydrocarbons (PAHs) assayed for biodegradation in contaminated soils

This study describes the development of a high throughput procedure for the extraction, purification, and quantification of all 16 polycyclic aromatic hydrocarbons (PAHs) on EPA's priority list, subject to biodegradation assays in a creosote-contaminated soil. We used various combinations of solvents, temperatures, ultrasonication, tumbling, saponification, vacuum centrifugation, adsorption chroma

Electrolytes based on LiClO4 and branched PEG-boronate ester polymers for electrochromics

Structure-property relationships of polymers incorporating Lewis acidic boron in their branched chain architecture were investigated as a function of LiClO4 salt concentration. The polymers were synthesised from boron trioxide, and different poly(ethylene glycol)s (PEGs) and monomethyl ether end-capped PEGs. The PEG-boronate ester polymers based on PEGs having molecular weights equal to, or below,

Fetal growth predicts stress susceptibility independent of parental education in 161 991 adolescent Swedish male conscripts.

Psychosocial stress could lead to a wide range of possible physiological reactions, due to both the total burden of stress as well as individual susceptibility. Two useful Swedish registers to investigate early life influences on stress susceptibility are the Swedish Medical Birth Register (MBR) and the Military Service Conscription Register (MSCR). In a previous study we showed a positive relatio

Altered brain exposure of morphine in experimental meningitis studied with microdialysis

Background: During pathologic conditions such as meningitis and traumatic brain injury the function of the blood-brain barrier (BBB) is disturbed. In the present study we examined the cerebral pharmacokinetic pattern of morphine in the intact brain and during experimentally induced meningitis using a pig model. Secondly, the use of intracerebral microdialysis as a potential tool for monitoring dam

Quality assessment of localization technique performance in small volume in vivo 1H MR spectroscopy

A new phantom and evaluation method for experimental evaluation of 1H-magnetic resonance spectroscopy single volume localization techniques regarding signal contamination (C), defined as the part of the signal originating outside the volume of interest, is presented. The quality assessment method is based on a spherical phantom with an oil/water interface in order to reduce susceptibility effects,

Are oral contraceptives masking symptoms of chlamydial cervicitis and pelvic inflammatory disease?

Tubal factor infertility is often diagnosed without any documented history of pelvic inflammatory disease. Chlamydial infection is one of the most common causes of pelvic inflammatory disease and likely also of infertility and ectopic pregnancy. Oral contraceptives may alter the course of chlamydial infections which may mask the clinical expression of the disease. This paper considers a number of

Single-shot two-dimensional ballistic imaging of the liquid core in an atomizing spray

We have developed a technique to image the near-field liquid core within an atomizing spray. To obtain high-fidelity images of the liquid core in such a spray has been very challenging up to this point. In this article, however, we describe the successful use of a time-gated ballistic imaging instrument to obtain high spatial resolution, single-shot images of the liquid core in an atomizing water

Brevican-deficient mice display impaired hippocampal CA1 long-term potentiation but show no obvious deficits in learning and memory

Brevican is a brain-specific proteoglycan which is found in specialized extracellular matrix structures called perineuronal nets. Brevican increases the invasiveness of glioma cells in vivo and has been suggested to play a role in central nervous system fiber tract development. To study the role of brevican in the development and function of the brain, we generated mice lacking a functional brevic

The influence of substrate pH on carbon translocation in ectomycorrhizal and nonmycorrhizal pine-seedlings

The effects of changed substrate pH on translocation and partitioning of C-14-labelled plant assimilates were examined in laboratory microcosms containing mycorrhizal (unidentified fungal isolate 'Pink FMT 87:2') and non-mycorrhizal seedlings of Pinus sylvestris L. and Pinus contorta Dougl. ex Loud. The mycorrhizal plants had intact mycelial systems at different developmental stages, and microcosm
