In a 5-year follow-up study of 88 animal exposed laboratory technicians, the incidence of laboratory animal allergy (LAA), lung function, and the development of allergy test reactivity were investigated. Only two individuals developed test positive LAA rhinitis during the follow-up period. Furthermore, one subject who had previously had LAA rhinitis developed LAA asthma. In the remaining subjects
In this paper results are presented from a range of experiments to explore the feasibility of inserting a ceramic material PZT (lead zirconium titanate) into different kinds of high-aspect-ratio resist moulds. Polymethylmethacrylate (PMMA) and SU-8 on silicon substrates and free-standing SU-8 membranes with microcavities or through-holes (defined by X-ray lithography) have been used as moulding me
Macroporous gels (MGs) with a broad variety of morphologies are prepared using the cryotropic gelation technique, i.e. gelation at subzero temperatures. These highly elastic hydrophilic materials can be produced from practically any gel-forming system with a broad range of porosity extending from elastic and porous gels with pore sizes up to 1.0 mu m to elastic and sponge-like gels with pore sizes
The aim of this study was to evaluate the ability of intravascular ultrasound to diagnose tumor involvement of the portal and the superior mesenteric veins using the preoperative percutaneous, transhepatic approach, and to compare the findings with those made at concomitant direct portography, surgery, and histopathological examination. Ten patients with a preoperative diagnosis of a resectable tu
The inflammatory mediator leukotriene B(4) (LTB(4)) binds to and activates a G-protein-coupled receptor named BLT(1). We have previously produced two monoclonal antibodies, named 7B1 and 14F11, that bind specifically to this receptor. Using a HeLa cell line expressing human BLT(1), we find that both antibodies inhibit LTB(4)-induced calcium release, and activation of a MAP-kinase-sensitive lucifer
This study was aimed at investigating the psychometric properties of the Interview Schedule for Social Interaction (ISSI), in terms of construct and discriminant validity and unidimensionality, in three psychiatric samples with varying prerequisites for social interaction: 1) an outpatient sample of working age with mixed diagnoses, 2) an outpatient sample with schizophrenia, and 3) an inpatient s
Electrical characteristics of living tissues have been investigated for a long time in the search for further methods to complement the traditional investigations of pathology and physiology. Tumour tissue has been shown to exhibit a larger permittivity and conductivity than normal tissues. This might be associated with the fact that tumour cells have a higher water content and sodium concentratio
Fluorescence in situ hybridisation (FISH) is a common and popular method used to investigate microbial populations in natural and engineered environments. DNA oligonucleoticle probes require accurate determination of the optimal experimental conditions for their use in FISH Oligonucleotides targeting the rRNA of methanogenic Archaea at various taxonomic levels have previously been published, altho
The gallium abundance in HgMn stars has been reported to be different for analyses conducted from spectral lines in the optical versus those from the ultraviolet. We pursue this ultraviolet-optical discrepancy from a line-blending perspective by investigating the Hubble Space Telescope (HST) Space Telescope Imaging Spectrograph (STIS) spectrum of the sharp-lined HgMn binary star chi Lup. Its galli
Host-related and environmental factors for tuberculosis have usually been investigated separately using different study designs. Joint investigation of the genetic, immunologic, and environmental factors at play in susceptibility to tuberculosis represents an innovative goal for obtaining a better understanding of the pathogenesis of the disease. In this paper, the authors describe methods being u
Wireless sensor networks are composed of a large number of sensor nodes with limited energy resources. Once deployed, the sensor nodes are usually inaccessible to the user, and thus replacement of the energy resource is not feasible. Hence, energy efficiency is a key design issue that needs to be enhanced in order to improve the life span of the entire network. Several routing protocols have been
Arsenic enrichment of groundwater in the Red River (Song Hong) delta in Vietnam was discovered in 1998. Several studies performed in this area found concentrations of As exceeding the WHO-guideline of 10 lg/L. This study focuses on an area south of Hanoi city, Nam Du, where a new well field came into operation in 2004. The new well field is situated on the bank along the Red River in order to faci
Molecular factors control the developmental ingrowth of axons to the tooth pulp. Here we examine the ability of pulpal cells to induce neurite outgrowth from neonatal rat trigeminal neurones (TGNs) in vitro. We found that TGNs emitted neurites and formed networks of branches in relation to pulpal cells. Neurones co-cultured with a mixture of pulpal cells and 3T3 fibroblasts formed networks exclusi
Human cathelicidin antimicrobial protein hCAP18/LL-37 is an effector molecule of the nonspecific innate immune system. hCAP18/LL-37 is present in leukocytes and is expressed in skin and other epithelia, where it is upregulated in association with inflammation and injury. In addition, antimicrobial proteins including cathelicidins have been proposed to play a role in the nonspecific defense against
Conversion of lignocellulosic material to monomeric sugars and finally ethanol must be performed at low cost, i.e, with limited consumption of chemicals, yeast and enzymes while still reaching high yields, if it is to compete with other fuel conversion processes. The objective of this study was thus to investigate ethanol production from steam-pretreated wheat straw by simultaneous saccharificatio
We studied clinical performance of serum TRACP 5b and other bone turnover markers, including S-CTX, U-DPD, S-PINP, S-BALP, and S-OC, for monitoring alendronate treatment. TRACP 5b had higher clinical sensitivity, area under the ROC curve, and signal-to-noise ratio than the other markers. INTRODUCTION: The purpose of this study was to compare the clinical performance of serum TRACP 5b (S-TRACP5b) w
Previous studies suggested a link between the use of G-CSF and increased incidence of myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) after immunosuppressive therapy (IST) for severe aplastic anemia (SAA). This European survey included 840 patients who received a first-line IST with (43%) or without (57%) G-CSF. The incidences of MDS/AML in patients who did or did not receive G-CSF
