The objective was to compare volume blood flow (VBF) in the descending aorta (DAo) of gestational age and weight-matched growth restricted (GR) and normal (N) fetuses. A longitudinal study of 20 N was compared with 11 GR in two analyses matched for weight and gestation. DAo dimensions and flow velocity were measured simultaneously using a new technique combining an ultrasonic phase-locked echo-tra
A dominant notion that homosexuality and heterosexuality give meaning to bisexuality already exists. But no one has explored the meaning that bisexuality might accrue with regard to monosexuality. Because bisexuals were never fully recognized within queer theory, the homosexual-heterosexual binary opposition continues to be the primary understanding of difference. Further, within queer theory, the
A myoelectric control system for prostheses was developed and evaluated on six healthy subjects. These were able to control a computer-animated hand in real-time with a 20 Hz update rate. A data glove, equipped with joint angle sensors, was used to train the system and to evaluate the continuous predictions of joint angles. A linear envelop filter was used for EMG signal pre-processing and the rec
PURPOSE: To assess the visual results, retinal detachment (RD) rate, incidence of glaucoma, and intraocular lens (IOL) placement after vitrectomy for removal of retained lens fragments in the vitreous after phacoemulsification. SETTING: Department of Ophthalmology, University Hospital of Lund, Lund, Sweden. METHODS: This retrospective noncomparative interventional case series included all cases of
BACKGROUND: The objective of the present study was to optimize conditions for retroviral transduction of human cord blood (CB) CD34+ cells and to reveal mechanisms which interfere with efficient gene transfer. METHODS: An MSCV based retroviral vector with the gene for enhanced green fluorescent protein (MGIN) produced by GP+envAM12 (amphotropic envelope), PG13 (gibbon ape leukemia virus envelope)
Abstract in SpanishResumen: La tarea de la semiótica de la imagen no consiste solamente en determinar la especificidad de la imagen como signo, sino también en describir las particularidades de diferentes imágenes, como son, por ejemplo, el dibujo, la fotografía y la imagen de computadora. El presente texto describe, primero, el desarrollo del signo del tipo de laAbstract: The task of pictorial se
The elicitation of a positive patch test reaction in a given individual depends upon the dose of the sensitizer applied, the patch test technique and the occlusion time. The dose is determined by the concentration and volume/amount of test preparation applied. If the same amount/volume of a test preparation is applied all the time with the same test technique (same area of skin) and occlusion time
The importance of sexual selection in population divergence is of much interest, mainly because it is thought to cause reproductive isolation and hence could lead to speciation. Sexually selected traits have been hypothesized to diverge faster between populations than other traits, presumably because of differences in the strength, mechanism or dynamics of selection. We investigated this by quanti
An overview of the new field of Gas in Scattering Media Absorption Spectroscopy (GASMAS) is presented. GASMAS combines narrow-band diode-laser spectroscopy with diffuse media optical propagation. While solids and liquids have broad absorption features, free gas in pores and cavities in the material is characterized by sharp spectral signatures, typically 10,000 times sharper than those of the host
We present a capacitance-voltage study for arrays of vertical InAs nanowires. Metal-oxide-semiconductor (MOS) capacitors are obtained by insulating the nanowires with a conformal 10 nm HfO2 layer and using a top Cr/Au metallization as one of the capacitor's electrodes. The described fabrication and characterization technique enables a systematic investigation of the carrier density in the nanowire
We present a web-based method for mapping various relations between agents that have been involved in an emergency response operation. The method is based on combining a web-questionnaire with telephone interviews and it provides an efficient way of collecting large amount of information concerning the agents. By using the resulting network of agents it is possible to perform various network analy
We have examined the effects of three macrophagederived cytokines, platelet-derived growth factor (PDGF), transforming growth factor-01 (TGF-01) and interleukin-1 a (IL-la) on the contraction of collagen type I gels populated by human foreskin fibroblasts. Contraction was quantified as loss in gel weight. Both PDGF-AA and PDGF-BB were found to induce a rapid collagen-gel contraction. TGF-/J1 also
The ISOLDE RIB-facility at CERN has today been producing a vast range of radioactive beams since more than 30 years. The low-energy beams of ISOLDE will be complemented by a post-accelerator, REX-ISOLDE, currently being assembled. In order to convert the pseudo-DC, singly-charged beam from the ISOLDE mass separators into a cooled and bunched beam at higher charge states, a novel scheme of trapping
We find effective, or homogenized, material parameters for Maxwell's equations when the microscopic scale becomes small compared to the scale induced by the frequencies of the imposed currents. After defining a singular value decomposition of the non-self-adjoint partial differential operator, we expand the electromagnetic field in the modes corresponding to the singular values and show that only
Different simple methods for evaluating the diffusivity from a sorption measurement are presented and tested when there is a surface resistance (a limited mass transfer coefficient), a non-perfect step in relative humidity or non-Fickian effects. It is concluded that the different methods have different qualities and it is impossible to give a general recommendation on which method to use. The bes
Although the calcineurin inhibitors (CNI) cyclosporine (CsA) and tacrolimus are highly effective immunosuppressants, they are associated with serious side effects. There is great interest in immunosuppressive regimens that permit reduction or elimination of CNIs, while maintaining adequate immunosuppression and acceptable acute rejection rates. Patients (n = 536) receiving their first renal allogr
Treatment of haemophilia is extremely costly due to the short biological half-life of infused factor and pricing issues. This paper examines the impact of different dosing schedules on factor consumption, via a review of literature on dosing regimens used for prophylaxis with a focus on pharmacokinetics (PK). Pharmacokinetics were found to have an important role for pharmacoeconomics in factor dos
Transmembrane receptors with intrinsic serine/threonine or tyrosine kinase domains regulate vital functions of cells in multicellular eukaryotes, e.g., differentiation, apoptosis, and proliferation. Here, we show that bone rnorphogenetic protein type II receptor (BMPR-II)which has a serine/threonine kinase domain, and stem cell factor receptor (c-kit) which contains a tyrosine kinase domain form a
The content of the globular domains G1, G2 and G3 on the core protein of high-density (A1D1) aggrecan isolated from newborn and mature bovine cartilage and from cultures of bovine chondrocytes was examined. Quantitation based on the 220 nm absorbance of tryptic marker peptides from each domain isolated by reversed-phase HPLC showed that while the content of G1 and G2 was essentially the same for a
