Hiatella is one of the most widespread marine bivalve genera, occurring in diverse habitats from the temperate to polar latitudes in both hemispheres, and in fossil strata since almost 150 Myr ago. Despite variation in some biological and morphological traits, characters to resolve the current systematic structure consistently across the range of the genus are not known: all samples are often refe

We present evidence of mitochondrial and nuclear introgression from the Atlantic herring Clupea harengus into the Pacific herring C. pallasii in northern European seas, where the two species have come into secondary contact following the post-glacial trans-Arctic invasion of Pacific herring to the Atlantic realm. Although the breeding areas of the two species are thought to be separate, 7 % of the

BackgroundThe relationships between North Atlantic and North Pacific faunas through times have been controlled by the variation of hydrographic circumstances in the intervening Arctic Ocean and Bering Strait. We address the history of trans-Arctic connections in a clade of amphi-boreal pelagic fishes using genealogical information from mitochondrial DNA sequence data. The Pacific and Atlantic herr

The Japanese skeleton shrimp Caprella mutica, originally from the north-west Pacific, artificially introduced to many parts of the world, is recorded in Sweden for the first time. The new record is from Eastern Skagerrak, slightly north of the border between the North Sea and the Baltic Sea. A detailed morphological description of the specimens from Swedish waters with notes on habitat is presente

Objective: Population-based osteoarthritis (OA) cohorts provide vital data on risk factors and outcomes of OA, however the methods to define OA vary between cohorts. We aimed to provide recommendations for combining knee and hip OA data in extant and future population cohort studies, in order to facilitate informative individual participant level analyses. Method: International OA experts met to m

We investigate the population of high-redshift (3≤z < 6) active galactic nuclei (AGN) selected in the two deepest X-ray surveys, the 7 Ms Chandra Deep Field-South and 2 Ms Chandra Deep Field-North. Their outstanding sensitivity and spectral characterization of faint sources allow us to focus on the sub-L* regime (logLX ≲ 44), poorly sampled by previous works using shallower data, and the obscured

This paper summarizes and elaborates on some new results on the optimal absorption in small spherical suspensions based on electrophoretic (plasmonic) resonances and lossy surrounding media. The main application here is to study the physical limitations for radio frequency absorption in gold nanoparticle (GNP) suspensions and its potential to achieve GNP targeted hyperthermia in cancer therapy. Nu

Background: The cerebral aqueduct is a central conduit for cerebrospinal fluid (CSF), and non-invasive quantification of CSF flow in the aqueduct may be an important tool for diagnosis and follow-up of treatment. Magnetic resonance (MR) methods at clinical field strengths are limited by low spatial resolution. Purpose: To investigate the feasibility of high-resolution through-plane MR flow measure

Introduction: In healthy carriers of the T allele of the transcription factor 7-like 2 (TCF7L2), fasting plasma glucagon concentrations are lower compared with those with the C allele. We hypothesised that presence of the T allele is associated with a diminished glucagon response during hypoglycaemia and a higher frequency of severe hypoglycaemia (SH) in type 1 diabetes (T1DM). Material and method

INTRODUCTION: The EUROpean Bone Over 40 Sarcoma Study (EURO-B.O.S.S.) was the first prospective international study for patients 41-65 years old with high-grade bone sarcoma treated with an intensive chemotherapy regimen derived from protocols for younger patients with high-grade skeletal osteosarcoma.METHODS: Chemotherapy based on doxorubicin, cisplatin, ifosfamide, and methotrexate was suggested

Life time occurrence of inguinal hernia is 30% of men. Most are symptomatic and will require surgical treatment. Operation will commonly cure the hernia but remaining chronic pain or new pain is seen in 10–15%. Groin pain due to an inguinal hernia can cause impairment of sexual functions. This is sparsely studied. The aim was to analyse postoperative long term chronic pain and sexual impairment in

Background: There is limited knowledge about the perspective of patients undergoing allogeneic haematopoietic stem cell transplantation (HSCT) about having a sibling as donor. It is essential to understand the main concerns of stem cell recipients in order to enable nurses to provide person-centred care. Objectives: The study aim was to explore patients’ main concerns about having a sibling stem c

Stroke is a significant cause of long-term disability, impairing over 10 million peoples motor function, primarily on one side of the body every year. Whilst effective rehabilitation exercises can help recover and maintain some affected motor function, stroke survivors often do not carry out enough of these. Instead relying on their `good' side to carry out tasks. However, this leads to poor recov

A search for the associated production of the Higgs boson with a top quark pair (ttH) is reported. The search is performed in multilepton final states using a data set corresponding to an integrated luminosity of 36.1 fb-1 of proton-proton collision data recorded by the ATLAS experiment at a center-of-mass energy s=13 TeV at the Large Hadron Collider. Higgs boson decays to WW∗, ττ, and ZZ∗ are tar

A search for the standard model Higgs boson produced in association with a top-quark pair, ttH, is presented. The analysis uses 36.1 fb-1 of pp collision data at s=13 TeV collected with the ATLAS detector at the Large Hadron Collider in 2015 and 2016. The search targets the H→bb decay mode. The selected events contain either one or two electrons or muons from the top-quark decays, and are then cat

The chapter discusses the principle of legal separation of entities and its ramifications in the transnational human rights context. There have been calls to hold multinational enterprises accountable for human rights infringements in their global value chains. Some argue that lead firms should be subjected to a legal obligation of due diligence that would compel them to oversee subsidiaries and c
