Objectives The aim of the present study was to evaluate weather early supervised exercise improves recanalization of acute deep vein thrombosis (DVT) and reduces symptoms. Patients and methods From September 2001 to March 2004, of 381 patients, 72 eligible patients were included and with a mean age 54 +/- 14 years, 39 (52%) men with deep vein thrombosis ( DVT) proven with phlebography were randomi
Since 1,5 years wireless enteroscopy with the GivenM2A-capsule has been tested clinically. Wireless capsule-enteroscopy (WCE) has already contributed significantly to the understanding of patients with obscure intestinal symptoms. Series of occult bleeders show that WCE detects lesions in 60%, whereas enterography only in 15%, and push-enteroscopy in 25%. Lesions detected are angiodysplasia in 55
Six new putative cysteine protease inhibitors based upon sequences of the N-terminal binding fragments of rat cystatin A, bovine cystatin C and human cystatins D and S were synthesized, inhibitory activities of these compounds against papain and bovine cathepsin B were tested. Additionally, agar well diffusion test of their antibacterial activity against Streptococcus pyogenes was performed.
This paper presents findings from two explorative studies. One is a consumer study based on interviews with consumers in real store settings and one is a study based on interviews with fruit and vegetable managers of stores affiliated with a major food retail chain in Sweden. The aim of both studies was to explore the role of the grocery store for the consumers' choice of organic versus convention
A search for scalar top quarks in R-parity violating supersymmetry is performed in e(+)p collisions at HERA using the H1 detector. The data, taken at roots = 319 GeV and 301 GeV, correspond to an integrated luminosity of 106 pb(-1). The resonant production of scalar top quarks t in positron quark fusion via an R-parity violating Yukawa coupling lambda' is considered with the subsequent bosonic sto
By screening blood samples from patients with autosomal dominant retinitis pigmentosa, we found in one of the families a rhodopsin mutation (Pro-267-Leu), which segregates with the disease in two affected and five unaffected family members. Here, we present the results of the clinical evaluation of the family, including full-field electroretinography from the two affected family members. A 25-year
PURPOSE: Limited integration is consistently observed between subretinal transplants and host retinas. In the current study, an in vitro model system for studying connections forming between two abutting retinas was developed.METHODS: Neuroretinas were dissected from normal wild-type (WT) mice and green fluorescent protein (GFP) transgenic mice (obtained at postnatal days [P]0, P5, or P60), as wel
It is shown that the complete linkage clustering of n points in R-d, where d greater than or equal to 1 is a constant, can be computed in optimal O(nlogn) time and linear space, under the L-1 and L-infinity-metrics. Furthermore, for every other fixed L-t-metric, it is shown that it can be approximated within an arbitrarily small constant factor in O(nlogn) time and linear space.
The identification and quantification of 20 different polynuclear aromatic hydrocarbons (PAHs) in the fly ash from a pressurized fluidized bed (PFB) air gasification system based:on hot gas filtering were determined by GC-MS analysis. A comparison was made on the basis of the results from two different sets of experiments with varied gasifier feedstock. The first set included four experiments with
The growth of ultrathin ZrO2 films on Si(100)-(2 x 1) and Si(111)-(7 x 7) has been studied with core level photoelectron spectroscopy and X-ray absorption spectroscopy. The films were deposited sequentially by chemical vapor deposition in ultra-high vacuum using zirconium tetra-tert-butoxide as precursor. Deposition of a > 50 angstrom thick film leads in both cases to tetragonal ZrO2 (t-ZrO2), whe
Free clusters produced by a co-expansion of argon and krypton have been studied by means of core level photoelectron spectroscopy. In this study we have determined: (i) the produced clusters are heterogeneous; (ii) the radial distribution of the two atomic species in the cluster differs. The proposed structure model places the majority of the krypton atoms in the bulk, leaving the argon atoms to b

UWB technology provides an excellent means for wireless positioning due to its high resolution capability in the time domain. Its ability to resolve multipath components makes it possible to obtain accurate location estimates without the need for complex estimation algorithms. In this article, theoretical limits for TOA estimation and TOA-based location estimation for UWB systems have been conside
We studied the energy and protein balance of a Thrush Nightingale Luscinia luscinia, a small long-distance migrant, during repeated 12-hr long Eights in a wind tunnel and during subsequent two-day fueling periods. From the energy budgets we estimated the power requirements for migratory flight in this 26 g bird at 1.91 Watts. This is low compared to flight cost estimates in birds of similar mass a
