General expressions for the quality factor (Q) of antennas are minimized to obtain lower-bound formulas for the Q of electrically small, lossy or lossless, combined electric and magnetic dipole antennas confined to an arbitrarily shaped volume. The lower-bound formulas for Q are derived for the dipole antennas excited by both electric and magnetic surface currents as well as by electric surface cu
Three different SPE sorbents (weak cation exchange, mixed cation exchange, and hydrophobic-lipophilic balance polymers) were compared in terms of recovery, precision, and the effect of matrix components on analyte response for the determination of fluoroquinolones antibiotics. The influence of ethylenediaminetetraacetic acid disodium salt (Na(2)-EDTA) was as well tested. Two of the sorbents, hydro
To compare the postoperative computed tomography angiography (CTA) assessment made by vascular surgeons and interventional radiologists after endovascular aneurysm repair (EVAR) at a tertiary vascular clinic to an outside core review facility.
Introduction: In the prehospital care of a cold and wet person, early application of adequate insulation is of utmost importance to reduce cold stress, limit body core cooling, and prevent deterioration of the patient’s condition. Most prehospital guidelines on protection against cold recommend the removal of wet clothing prior to insulation, and some also recommend the use of a waterproof vapor b
BACKGROUND AND AIM: Persistent organochlorine pollutants (POPs) have in epidemiological studies been associated with health hazards. The exposure window might be crucial and it is, accordingly, important to analyze exposure concentrations in samples collected at the window of interest. This makes the use of stored blood samples extremely interesting. However, small blood volumes from stored sampl
Diamond-Blackfan anemia (DBA) is a congenital erythroid hypoplasia caused by a functional haploinsufficiency of genes encoding for ribosomal proteins. Among these genes, ribosomal protein S19 (RPS19) is mutated most frequently. Generation of animal models for diseases like DBA is challenging since the phenotype is highly dependent on the level of RPS19 downregulation. We report the generation of m
While scientific community disagrees about similarities and differences between human embryonic stem (hES) cells and human induced pluripotent stem (hiPS) cells, some politicians embrace translational hiPS cell research as a replacement for translational hES cell research. We examine the ethical relevance of the main differences between hES and hiPS cell-based therapies and discuss whether, given
Exhaustion is hypothesised to be a risk-factor for coronary heart disease (CHD), but as such its independence from emotional states, in particular depression, has not been established in previous investigations. This study aimed to explore the unique contribution of exhaustion, independent from symptoms of depression and anxiety, to CHD development.
Interim methadone treatment (i.e. temporary medication-only treatment) has been tested in a few US studies as a method for facilitated referral to and initiation of opioid maintenance treatment in heroin dependence. However, despite the favorable safety profile of buprenorphine compared to methadone, interim treatment with buprenorphine rarely has been tested and reported in the scientific literat
Understanding of the functions and mechanisms of fundamental processes in the cell requires structural information. Structural studies of membrane proteins typically necessitate large amounts of purified and preferably homogenous target protein. Here, we describe a rapid overproduction and purification strategy of a bacterial PIB-type ATPase for isolation of milligrams of target protein per liter
The capability of retrieving spectral information from line shapes recorded by two-tone frequency-modulation spectroscopy (TTFMS) is investigated. A TTFMS theory accounting for dispersion and nonlinear distortion of diode laser frequency modulation response is presented. The adequacy of the theory for a detailed modeling of line shapes recorded with high resolution is examined. An extensive error
In this study using cross-sectional survey data from suburban and rural Scania, Sweden (N=24,847), we assessed how the recently validated index score of area-aggregated perceived green neighborhood qualities (Scania Green Score; SGS), and the five distinct qualities within this index were associated with three self-reported indicators of well-being: neighborhood satisfaction, physical activity and
AIM: To survey the histopathological abnormalities in breasts of women who have undergone risk reducing mastectomy and to evaluate the effect of this measure on future breast cancer development. PATIENTS/METHODS: Between August 1995 and October 2006 100 consecutive women with a hereditary increased risk of breast cancer underwent prophylactic mastectomy (PM) at Malmö University Hospital. Fifty of
BACKGROUND: Iron deficiency may impair aerobic performance. This study aimed to determine whether treatment with intravenous iron (ferric carboxymaltose) would improve symptoms in patients who had heart failure, reduced left ventricular ejection fraction, and iron deficiency, either with or without anemia. METHODS: We enrolled 459 patients with chronic heart failure of New York Heart Association (
This article attempts to prove that an adequate cognition oriented approach to the processing of symbolic information abstracted from verbal expressions must consider a running text instead of scattered sentences. It is argued that the dominant cognition models do not give due consideration to the fact that a valid abstraction of in-formation structures has to be based on an explicit encoding of i
