A method of correcting the asymmetry in the scattering of the tangential beam configuration in a rheo-small-angle neutron scattering experiment is proposed. The asymmetry of the scattering in the tangential beam configuration can be attributed to the difference in pathlength for neutrons that are scattered toward compared with those which are scattered away from the axis of rotation of the shear c

The purpose of this study was to retrospectively evaluate interventional radiological management of patients with symptomatic portal hypertension secondary to obstruction of splanchnic veins. Twenty-four patients, 15 males and 9 females, 0.75 to 79 years old (mean, 36.4 years), with symptomatic portal hypertension, secondary to splanchnic venous obstruction, were treated by percutaneous methods. C

BACKGROUND: The use of impacted morselized allograft bone and cement in hip revision arthroplasty has been popular, but studies that specifically address intraoperative and postoperative complications have been scarce. METHODS: All complications that occurred during, and within the first year after, 144 consecutive hip revision arthroplasties (108 stems and 130 sockets) performed with impacted mor

Legionella pneumophila serogroup 6 was recovered from a bronchoalveolar lavage specimen from a 1-week-old, full-term newborn with pneumonia, as well as from water samples from the maternity hospital and the newborn's home (an apartment). Amplified fragment-length polymorphism typing revealed that the strains isolated from the newborn and her home were indistinguishable from each other but were cle

The social networks of individuals with severe mental illness admitted to long-term in-patient settings and living in two types of supported housing, small congregate community residences and independent living with support, were compared. The Interview Schedule for Social Interaction (ISSI) was used. The results showed no substantial differences in social networks between the two types of support

High-repetition-rate laser-induced fluorescence measurements of fuel and OH concentrations in internal combustion engines are demonstrated. Series of as many as eight fluorescence images, with a temporal resolution ranging from 10 mus to 1 ms, are acquired within one engine cycle. A multiple-laser system in combination with a multiple-CCD camera is used for cycle-resolved imaging in spark-ignition

The Serial Color Word Test was administered at baseline to 253 hypertensive men participating in the prospective cohort study of cardiovascular diseases "Men born in 1914" in Malmo, Sweden. This test of psychological adaptation to a stressful encounter was used to investigate whether susceptibility to stress moderates the risk of a cardiac event in association with hypertension. Adaptive behavior,

Chronic diseases (CD) represent the main cause of mortality in developed countries. The increase in the prevalence of of CD is associated with changes in lifestyle habits, including those related to the consumption of processed foodstuffs. In these foods advanced glycation end products (AGE) and advanced lipoperoxydation products (ALE) are formed as a consequence of the reactivity of proteins, car

Population fluctuations may occur in synchrony among several rodent species at a given site, and they may occur in synchrony over large geographical areas. We summarize information on synchrony in lemmings and voles from the Canadian Arctic for the past 20 years. The most detailed available information is from the central Canadian Arctic, where snap-trap samples have been taken annually at several

Background and aims After resection and repair of the intestines, tissue degradation leads to weakening of the repair site and risk of postoperative leakage. Matrix metalloproteinases (MMPs) are thought to be responsible for collagenolysis in the direct vicinity of surgical sutures in many tissues. Several experimental studies show that MMP inhibitors administered systemically alleviate postoperat

The accumulation of inositol monophosphate (IP1) was measured after stimulation of 5-hydroxytryptamine2 (5-HT2) receptors on platelets from alcoholics and healthy controls. In controls, 5-HT induced a dose-dependent response with an EC50 = 2 x 10(-6) M and a maximal response at 10(-5) M. Ritanserin, a selective 5-HT2 antagonist, markedly reduced the accumulation. The IP1 formation after stimulatio

Introduction: Activation recovery time (ART), defined as the time from the earliest ventricular activation time to the end of T wave on unipolar electrograms, has been used as an index of myocardial repolarization time. However, it is unknown whether the ART can be used to estimate the global sequence and dispersion of ventricular repolarization as determined by the monophasic action potential (MA

Control systems are often built using visual dataflow-based languages, and supporting different variants may be challenging. We introduce the concept of connection interception based on inheritance. This mechanism allows a diagram to extend another diagram and intercept connections defined in the supertype, that is, to replace it by two other connections, in order to specialize the behavior. This

Two macrocyclic peptides 3 and 4 were formed during lactamization of 1,1'-ferrocenylbis(alanine) 1. Isolation, structure determination, and conformational analysis of 3 and 4 are reported as well as a controlled stepwise synthesis of 4 also including an improved route to 1. On the basis of their H-1 NMR spectra recorded at 300 K in DMSO-d(6), the dimer 3 and trimer 4 were found to be C-2 and C-3 s

We hereby report on a three year project initiative undertaken by our research team encompassing large-scale protein expression profiling and annotations of human primary lung fibroblast cells. An overview is given of proteomic studies of the fibroblast target cell involved in several diseases such as asthma, idiopatic pulmonary disease, and COPD. It has been the objective within our research team
