Beyond Average : a-Particle Distribution and Dose Heterogeneity in Bone Metastatic Prostate Cancer

a-particle emitters are emerging as a potent modality for disseminated cancer therapy because of their high linear energy transfer and localized absorbed dose profile. Despite great interest and pharmaceutical development, there is scant information on the distribution of these agents at the scale of the a-particle pathlength. We sought to determine the distribution of clinically approved [223Ra]R

Mass spectroscopy reveals compositional differences in copepodamides from limnic and marine copepods

Marine copepods, the most abundant animals in the global ocean, imprint their surrounding waters with chemical cues, called copepodamides. Copepodamides induce defensive traits such as toxin production, bioluminescence, and colony size plasticity in a variety of marine phytoplankton. The role of copepodamides in freshwater ecosystems is, however, unknown. Here we report the consistent presence of

Graphite oxide by “chlorate route” oxidation without HNO3 : Does acid matter?

Very strong difference in many properties is well documented for graphite oxides (GtO) synthesized by Brodie (BGO) and Hummers (HGO) methods. The difference is typically assigned to the type of oxidant (chlorates or KMnO4, respectively). However, not only oxidants but also acids used in these methods are different. It is still unclear which of the different properties of GtO are dependent on the o

Effects of certain pre-analytical factors on the performance of plasma phospho-tau217

Introduction: Pre-analytical factors can cause substantial variability in the measurements of cerebrospinal fluid (CSF) and plasma biomarkers of Alzheimer’s disease (AD). However, their effects on the performance of one of the most promising plasma AD biomarkers, phosphorylated tau (p-tau)217, are not known. Methods: We included 50 amyloid-β positive (Aβ+) and 50 Aβ− participants from the Swedish

Swedish musculoskeletal researchers view on a collaborative network and future research priorities in Swedish healthcare

Background: Musculoskeletal disorders (MSK) are a global burden causing significant suffering and economic impact. Systematic identification and targeting of research questions of highest interest for stakeholders can aid in improving MSK disorder knowledge and management. Objective: To obtain Swedish MSK researchers' opinions and views on a collaborative Swedish MSK network (SweMSK) and identify

Gender effects in dictator game giving under voluntary choice of the recipient's gender : Women favour female recipients

Allowing for free choice of the recipient's gender in a dictator game (N=357), women give more frequently to their own gender (70.3% vs 9.4%) while men do not prefer a specific recipient's gender (33.3% vs 27.8%). Conditional on a positive transfer being made, the average amount of transfers to each gender does not vary between genders, though. Once a charity recipient is added to the possible cho

Harmonic morphisms on Lie groups and minimal conformal foliations of codimension two

Let G be a Lie group equipped with a left-invariant semi-Riemannian metric. Let K be a semisimple subgroup of G generating a left-invariant conformal foliation F of codimension two on G. We then show that the foliation F is minimal. This means that locally the leaves of F are fibres of a complex-valued harmonic morphism. In the Riemannian case, we prove that if the metric restricted to K is biinva

The Coriolis effect and coupled oscillations in a rotating swings amusement ride

Rotating swings are found in many different versions in parks around the world. They are beautiful examples of the equivalence between gravitational and inertial mass: empty swings and swings with heavy adults hang at the same angle to the vertical. However, sometimes one can notice empty swings moving in a different pattern in an outdoor ride, where wind can induce additional motion, sideways or

Low achromatic contrast sensitivity in birds : a common attribute shared by many phylogenetic orders

Vision is an important sensory modality in birds, which can outperform other vertebrates in some visual abilities. However, sensitivity to achromatic contrasts - the ability to discern luminance difference between two objects or an object and its background - has been shown to be lower in birds compared with other vertebrates. We conducted a comparative study to evaluate the achromatic contrast se

Detecting Weak Underwater Targets Using Block Updating of Sparse and Structured Channel Impulse Responses

In this paper, we considered the real-time modeling of an underwater channel impulse response (CIR), exploiting the inherent structure and sparsity of such channels. Building on the recent development in the modeling of acoustic channels using a Kronecker structure, we approximated the CIR using a structured and sparse model, allowing for a computationally efficient sparse block-updating algorithm

How to Detect Antibodies Against Babesia divergens in Human Blood Samples

Background. Today only indirect fluorescent antibody assays (IFAs) are commercially available to detect antibodies against Babesia divergens in humans. IFA is subjective and requires highly experienced staff. We have therefore developed an enzyme-linked immunosorbent assay (ELISA)-based method for measuring anti-B. divergens immunoglobulin G antibodies in human blood samples. Methods. Crude merozo

The galactic acceleration scale is imprinted on globular cluster systems of early-type galaxies of most masses and on red and blue globular cluster subpopulations

Context. Globular clusters (GCs) carry information about the formation histories and gravitational fields of their host galaxies. It was found before that the radial profiles of the volume number density of GCs in GC systems (GCSs) follow broken power laws, while the breaks occur approximately at the a0 radii. These are the radii at which the gravitational fields of the galaxies equal the galactic

Patient-reported outcomes in axial spondyloarthritis and psoriatic arthritis patients treated with secukinumab for 24 months in daily clinical practice

Objectives: In patients with axial spondyloarthritis (axSpA) or psoriatic arthritis (PsA) initiating secukinumab, we aimed to assess and compare the proportion of patients achieving 6-, 12- and 24-month patient-reported outcomes (PRO) remission and the 24-month retention rates. Patients and methods: Patients with axSpA or PsA from 16 European registries, who initiated secukinumab in routine care w

Self-replication of Aβ42 aggregates occurs on small and isolated fibril sites

Self-replication of amyloid fibrils via secondary nucleation is an intriguing physicochemical phenomenon in which existing fibrils catalyze the formation of their own copies. The molecular events behind this fibril surface-mediated process remain largely inaccessible to current structural and imaging techniques. Using statistical mechanics, computer modeling, and chemical kinetics, we show that th

Reclaiming the Past and the Present: The Presentation and Representation of Ethnic Minorities in Cultural Institutions

Cultural institutions such as museums and art galleries are important agents in educating the broader public on matters where current awareness is missing, inadequate or inaccurate. In this study, I focus on one such matter, which is the knowledge regarding ethnic minorities, their history, traditions, and current challenges. My primary focus is on how cultural institutions utilise their exhibitio

Digital PCR quantification of ultrahigh ERBB2 copy number identifies poor breast cancer survival after trastuzumab

HER2/ERBB2 evaluation is necessary for treatment decision-making in breast cancer (BC), however current methods have limitations and considerable variability exists. DNA copy number (CN) evaluation by droplet digital PCR (ddPCR) has complementary advantages for HER2/ERBB2 diagnostics. In this study, we developed a single-reaction multiplex ddPCR assay for determination of ERBB2 CN in reference to

The Genetics of Diabetes

The chronic hyperglycaemia of diabetes is associated with long-term damage, dysfunction, and failure of different organs, especially the eyes, kidneys, nerves, heart, and blood vessels. The increasing prevalence of type 2 diabetes can largely be ascribed to the worldwide increase in obesity during the last 30 years; for instance, more than 60% of individuals older than 15 years in the UK and USA a

Angle estimation using mmWave RSS measurements with enhanced multipath information

mmWave communication has come up as the unexplored spectrum for 5G services. With new standards for 5G NR positioning, more off-the-shelf platforms and algorithms are needed to perform indoor positioning. An object can be accurately positioned in a room either by using an angle and a delay estimate or two angle estimates or three delay estimates. We propose an algorithm to jointly estimate the ang
