Patients' perspective on prostatic artery embolization : A qualitative study

Objectives: The aim was to describe the patients' experience of undergoing prostatic artery embolization.Methods: A retrospective qualitative interview study was undertaken with 15 patients of mean age 73 years who had undergone prostatic artery embolization with a median duration of 210 min at two medium sized hospitals in Sweden. The reasons for conducting prostatic artery embolization were clea

Persistent organic pollutants and the size of ovarian reserve in reproductive-aged women

Industrial chemicals such as persistent organic pollutants (POPs) have been associated with reduced fertility in women, including longer time-to-pregnancy (TTP), higher odds for infertility, and earlier reproductive senescence. Fertility is highly dependent on the ovarian reserve, which is composed of a prenatally determined stock of non-growing follicles. The quantity and quality of the follicles

Asynchronous δ13Ccarb and δ13Corg records during the onset of the Mulde (Silurian) positive carbon isotope excursion from the Altajme core, Gotland, Sweden

High-resolution paired analyses of δ13Ccarb and δ13Corg from a new drill core from Gotland, Sweden, demonstrate asynchronous positive change in the carbon isotope records during the onset of one of the major Silurian biogeochemical events known as the Mulde Event or “Big Crisis”. The detailed carbon isotope record presented here provides Δ13C (the difference between δ13Ccarb and δ13Corg) and allow

The two-loop perturbative correction to the (g − 2) μ HLbL at short distances

The short-distance behaviour of the hadronic light-by-light (HLbL) contribution to (g − 2)μ has recently been studied by means of an operator product expansion in a background electromagnetic field. The leading term in this expansion has been shown to be given by the massless quark loop, and the non-perturbative corrections are numerically very suppressed. Here, we calculate the perturbative QCD c

Catch-up dynamics in early industry lifecycle stages - A typology and comparative case studies in four clean-tech industries

The literature on catch-up cycles has not yet systematically conceptualized how catch-up dynamics differ between the various industries that are emerging in the green techno-economic paradigm. We address this gap by connecting catch-up cycle theory with an industry typology from global innovation systems (GISs) literature, which distinguishes four generic industry types with footloose, spatially s

Genome assembly, sex-biased gene expression and dosage compensation in the damselfly Ischnura elegans

The evolution of sex chromosomes, and patterns of sex-biased gene expression and dosage compensation, are poorly known among early winged insects such as odonates. We assembled and annotated the genome of Ischnura elegans (blue-tailed damselfly), which, like other odonates, has a male-hemigametic sex-determining system (X0 males, XX females). By identifying X-linked genes in I. elegans and their o

Influence of diabetes on diagnostic performance of computed tomography angiography of the calf arteries in acute limb ischemia

Background: Patients with diabetes mellitus (DM) have a more extensive distal arterial occlusive disease compared to non-diabetic patients. Diagnostic imaging is a necessity to identify the location and extent of the arterial occlusion in acute limb ischemia (ALI). Computed tomography angiography (CTA) is the most commonly used modality and the diagnostic performance with CTA of calf arteries may

Immune Profile in Patients With COVID-19 : Lymphocytes Exhaustion Markers in Relationship to Clinical Outcome

The velocity of the COVID-19 pandemic spread and the variable severity of the disease course has forced scientists to search for potential predictors of the disease outcome. We examined various immune parameters including the markers of immune cells exhaustion and activation in 21 patients with COVID-19 disease hospitalised in our hospital during the first wave of the COVID-19 pandemic in Slovakia

Agriculture for Development in the 21st Century : Evidence from Ethiopia

The 21st century has seen a rise of optimism about the prospects for African economic development, and Ethiopia, with its rapid economic growth in the last two decades, is at the forefront of this current wave of optimism. The rapid growth has been achieved under a policy focus on the agricultural sector – another aspect of development that has seen a renewed wave of optimism in the 21st century.

Gaia Early Data Release 3: Summary of the contents and survey properties

Context. We present the early installment of the third Gaia data release, Gaia EDR3, consisting of astrometry and photometry for 1.8 billion sources brighter than magnitude 21, complemented with the list of radial velocities from Gaia DR2. Aims. A summary of the contents of Gaia EDR3 is presented, accompanied by a discussion on the differences with respect to Gaia DR2 and an overview of the main l

Regional motion correction for in vivo photoacoustic imaging in humans using interleaved ultrasound images

In translation from preclinical to clinical studies using photoacoustic imaging, motion artifacts represent a major issue. In this study the feasibility of an in-house algorithm, referred to as intensity phase tracking (IPT), for regional motion correction of in vivo human photoacoustic (PA) images was demonstrated. The algorithm converts intensity to phase-information and performs 2D phase-tracki

Spatially resolved spectroscopy across stellar surfaces : V. Observational prospects: Toward Earth-like exoplanet detection

Context. High-precision stellar analyses require hydrodynamic 3D modeling. Testing such models is feasible by retrieving spectral line shapes across stellar disks, using differential spectroscopy during exoplanet transits. Observations were presented in Papers I, II, and III, while Paper IV explored synthetic data at hyper-high spectral resolution for different classes of stars, identifying charac

Spatially resolved spectroscopy across stellar surfaces : IV. F, G, and K-stars: Synthetic 3D spectra at hyper-high resolution

Context. High-precision stellar analyses require hydrodynamic 3D modeling. Such models predict changes across stellar disks of spectral line shapes, asymmetries, and wavelength shifts. For testing models in stars other than the Sun, spatially resolved observations are feasible from differential spectroscopy during exoplanet transits, retrieving spectra of those stellar surface segments that succes

Stability assessment of p-i-n perovskite photovoltaic mini-modules utilizing different top metal electrodes

Long-term stability is one of the major challenges for p-i-n type perovskite solar modules (PSMs). Here, we demonstrate the fabrication of fully laser-patterned series interconnected p-i-n perovskite mini-modules, in which either single Cu or Ag layers are compared with Cu/Au metalbilayer top electrodes. According to the scanning electron microscopy measurements, we found that Cu or Ag top electro

Dijet resonance searches for dark matter mediators using the ATLAS detector

Dark matter is abundant in the universe, yet its composition and nature are unknown. If dark matter consists of new particles with nonzero interactions with Standard Model particles, it could be produced and detected or inferred by collider experiments. This thesis describes searches for dark matter models with new spin-1 force mediators coupling dark matter to quarks, using the ATLAS detector at

The transformation of the forest steppe in the lower Danube Plain of southeastern Europe : 6000 years of vegetation and land use dynamics

Forest steppes are dynamic ecosystems, highly susceptible to changes in climate, disturbances and land use. Here we examine the Holocene history of the European forest steppe ecotone in the lower Danube Plain to better understand its sensitivity to climate fluctuations, fire and human impact, and the timing of its transition into a cultural forest steppe. We used multi-proxy analyses (pollen, n-al

Is there evidence for the racialization of pharmaceutical regulation? : Systematic comparison of new drugs approved over five years in the USA and the EU

Recent decades have seen much interest in racial and ethnic differences in drug response. The most emblematic example is the heart drug BiDil, approved by the US Food and Drug Administration in 2005 for “self-identified blacks.” Previous social science research has explored this “racialization of pharmaceutical regulation” in the USA, and discussed its implications for the “pharmaceuticalization o
