Pre-operative plasma cell-free circulating tumor DNA and serum protein tumor markers as predictors of lung adenocarcinoma recurrence

Background: Lung cancer patients have a risk of recurrence even after curatively intended surgery. Cell-free circulating tumor DNA (ctDNA) and circulating tumor marker measurements are easily accessible through peripheral blood and could potentially identify patients with worse prognosis. The aim of this study was to examine ctDNA in pre-operative plasma and the role of tumor markers in pre-operat

Patients’ experience of a workplace dialogue in physiotherapy practice in primary care : an interview study

Purpose: To describe how patients with acute/subacute back pain and/or neck pain experienced a workplace intervention, conducted as a structured workplace dialogue (convergence dialogue meeting, CDM) within physiotherapy practice in primary care. Materials and methods: Semi-structured interviews were performed with 10 patients who took part in the CDM. Qualitative content analysis was applied to t

Thermo-Hydraulic Performance Enhancement of Finned Elliptical Tube Heat Exchangers by Utilizing Innovative Dimple Turbulators

As a new type of fin structure in finned tube heat exchangers, dimple turbulators exhibit excellent potential for thermo-hydraulic performance enhancement. A three-dimensional numerical simulation study was conducted to investigate the influences of five kinds of innovative concave dimple turbulators (CDTs), namely–elliptical dimple, conical frustum dimple, trapezoidal prism dimple, leeward triang

Stability of signal apparition

The recently introduced method of `signal apparition' offers a fundamentally different approach to separation of multiple interfering sources, by using a periodic sequence of source signatures along one source line. This leads to exact separation of signals in diamond-shaped regions of the frequency-wavenumber domain which are twice as large compared to those recovered by other methods. In this pa

Flyttning hos grågäss enligt återfynd av fåglar märkta med traditionella metallringar i Sverige

Traditional recoveries of ringed Greylag Geese Anser anser from different regions in Sweden have been analyzed to compare the migration patterns from a number of different areas. During the years up to and including 2012, 7210 Greylag Geese were marked with metal rings from the Swedish Ringing Centre, yielding 1398 recoveries. After exclusion of local recoveries in the ringing area, 924 recoveries

Hypertonic Saline Infusion Acutely Degrades Mood in Healthy Volunteers (P23-014-19)

Objectives: Mild and moderate dehydration adversely affect mood and cognitive function. During dehydration, hypertonic hypovolemia activates both osmo- and baro-receptors but it is not known which physiological pathway is associated with degraded mood state. This study examined the acute effect of osmoreceptor stimulation on mood.Methods: Sixty healthy adults (50% females, 30 ± 1 y; BMI: 26.9 ± 4.

Enhancement of HFE-7200 pool boiling heat transfer on copper surfaces with nanoparticle coatings

Saturated pool boiling heat transfer of HFE-7200 is investigated experimentally on copper surfaces with nanoparticle coatings at atmospheric pressure. The coatings are generated by an electrophoretic deposition method. Two modified surfaces are prepared with Cu-Zinc nanoparticles of 0.3 mg and 0.6 mg, respectively. During the deposition, ethanol works as the solvent while the electrical potential

Trends of land surface phenology derived from passive microwave and optical remote sensing systems and associated drivers across the dry tropics 1992–2012

Changes in vegetation phenology are among the most sensitive biological responses to global change. While land surface phenological changes in the Northern Hemisphere have been extensively studied from the widely used long-term AVHRR (Advanced Very High Resolution Radiometer) data, current knowledge on land surface phenological trends and the associated drivers remains uncertain for the tropics. T

Post-tsunami survey of the 28 September 2018 tsunami near Palu Bay in Central Sulawesi, Indonesia : Impacts and challenges to coastal communities

Following the 7.5-Mw earthquake that occurred on 28 September 2018, a series of field surveys were performed to further understand the impacts of the resulting tsunami. Tsunamis initiated by strike-slip earthquakes are rare. Other factors are suspected to have contributed to this unusual tsunami. One of these factors was the subaerial landslides around Palu Bay, which were observed at several loca

Pituitary Metastases : A Nationwide Study on Current Characteristics with Special Reference to Breast Cancer

Objective To investigate the contemporary presentation of pituitary metastases. Patients Thirty-eight patients diagnosed with pituitary metastases from 1996 to 2018 in Sweden. Methods Pituitary metastases were confirmed by histopathology (n = 27) or considered highly likely according to radiological findings, including rapid tumor progression (n = 11). Medical records were reviewed and sellar imag

Uber Happy? Work and Well-being in the “Gig Economy”

We study the rise of the so-called “gig economy” through the lens of Uber and its drivers in the United Kingdom. Using administrative data from Uber and a new representative survey of London drivers, we explore their backgrounds, earnings, and subjective well-being. We find that the vast majority of Uber drivers are male immigrants, primarily drawn from the bottom half of the London income distrib

Synergistic effects of a cremophor EL drug delivery system and its U0126 cargo in an ex vivo model

Neuroprotection has proven clinically unsuccessful in subarachnoid hemorrhage. We believe that this is because the major component in the early damage pathway, the vascular wall, has not been given the necessary focus. U0126 is a potent inhibitor of vascular phenotypical changes, exemplified by functional endothelin B (ETB) receptor upregulation. The current study aimed to determine the optimal do

The European birch sawfly, Arge pullata(Hymenoptera: Argidae), in Sweden, and the firstnational record of its parasitoid Scolobates testaceus(Hymenoptera: Ichneumonidae)

The European birch sawfly Arge pullata (Zaddach) was found for the first time in Sweden in the early 2000s. According to a report in the local newspaper it was present on the Falsterbo peninsula, Skåne province, from 2000 at the latest, and in the following years a number of records were reported from the same restricted area. Subsequently it has expanded its range in southern Sweden. It is unusua

Probabilistic recognition of human faces from video

Most present face recognition approaches recognize faces based on still images. In this paper, we present a novel approach to recognize faces in video. In that scenario, the face gallery may consist of still images or may be derived from a videos. For evidence integration we use classical Bayesian propagation over time and compute the posterior distribution using sequential importance sampling. Th

Hydrogen and Hydrogen-Rich Fuels : Production and Conversion to Electricity

Hydrogen has been proposed as an energy carrier in storage systems, fueled by excess electricity from volatile power production and re-electrified in times of electricity shortage. Unfortunately, these storage systems suffer from fairly poor return efficiencies. There is however a multitude of other production methods and usages that not seldom are intermixed with storage, creating possibilities f
