A multiplex biomarker assay improves the diagnostic performance of HE4 and CA125 in ovarian tumor patients

Objective Survival in epithelial ovarian cancer (EOC) remains poor. Most patients are diagnosed in late stages. Early diagnosis increases the chance of survival. We used the proximity extension assay from Olink Proteomics to search for new protein biomarkers with the potential to improve the diagnostic performance of CA125 and HE4 in patients with ovarian tumors. Material and methods Plasma sample

Identification of the major rabbit and guinea pig semen coagulum proteins and description of the diversity of the REST gene locus in the mammalian clade Glires

The seminal vesicle secretions of guinea pig and rabbit were analyzed for semen coagulum proteins. Using SDS-PAGE we discovered a previously not fully recognized semen coagulum protein, Svp5, in the guinea pig and a single predominant component, SVP200, in the rabbit. Potential genes of these proteins were identified in genome databases by their homology with human and murine genes. The structure

Early migration of stemless and stemmed humeral components after total shoulder arthroplasty for osteoarthritis-study protocol for a randomized controlled trial

Background: Glenohumeral osteoarthritis can, in the most severe cases, require surgery with insertion of a shoulder arthroplasty. A design with a stem in the humeral bone canal is currently regarded as the standard treatment option in patients who have an intact rotator cuff function, but complications related to the stem including humeral fractures can have devastating consequences. By using a st

Targeted hypothermia versus targeted normothermia after out-of-hospital cardiac arrest : A statistical analysis plan

Background: To date, targeted temperature management (TTM) is the only neuroprotective intervention after resuscitation from cardiac arrest that is recommended by guidelines. The evidence on the effects of TTM is unclear. Methods/design: The Targeted Hypothermia Versus Targeted Normothermia After Out-of-hospital Cardiac Arrest (TTM2) trial is an international, multicentre, parallel group, investig

Overwhelmed by overflows? : How people and organizations create and manage excess

This book presents studies of ways in which people and organizations deal with the overflow of information, goods, or choices. The contributors explore two main themes. The first is the emergence of overflows: What is defined as overflow? Here the notion of framing as coined by Michel Callon has guided our approach. There is no overflow until some flow has been framed; framing means defining, and

Incest in Sweden 1680–1940 : A history of forbidden relations

För 300 år sedan avrättades en man och hans avlidna hustrus syster ifall det avslöjades att de hade haft sexuellt umgänge. Deras relation definierades som incestuös och benådningar var sällsynta. Incestförbuden omfattade då många fler relationskategorier än idag och fram till sent 1800-tal var de flesta incestuösa relationer frivilliga föreningar mellan två vuxna individer som saknade biologiska sThis study brings out the norms and culturally dependent values that formed the basis of the theoretical regulation and the practical handling of incest cases in Sweden 1680–1940, situating this development in a wider European context. It discusses a broad variety of general human subjects that are as important today as they were hundreds of years ago, such as love, death, family relations, religi

Loss of hepatocyte cell division leads to liver inflammation and fibrosis

The liver possesses a remarkable regenerative capacity based partly on the ability of hepatocytes to re-enter the cell cycle and divide to replace damaged cells. This capability is substantially reduced upon chronic damage, but it is not clear if this is a cause or consequence of liver disease. Here, we investigate whether blocking hepatocyte division using two different mouse models affects physi

Cyclin-dependent kinase 1 is essential for muscle regeneration and overload muscle fiber hypertrophy

Satellite cell proliferation is an essential step in proper skeletal muscle development and muscle regeneration. However, the mechanisms regulating satellite cell proliferation are relatively unknown compared to the knowledge associated with the differentiation of satellite cells. Moreover, it is still unclear whether overload muscle fiber hypertrophy is dependent on satellite cell proliferation.

Quantification of left ventricular contribution to stroke work by longitudinal and radial force-length loops

Left ventricular (LV) stroke work (SW) is calculated from the pressure-volume (PV) loop. PV loops do not contain information on longitudinal and radial pumping, leaving their contributions to SW unknown. A conceptual framework is proposed to derive the longitudinal and radial contributions to SW, using ventricular force-length loops reflecting longitudinal and radial pumping. The aim of this study

Visual adaptations in predatory and scavenging diurnal raptors

Ecological diversity among diurnal birds of prey, or raptors, is highlighted regarding their sensory abilities. While raptors are believed to forage primarily using sight, the sensory demands of scavengers and predators differ, as reflected in their visual systems. Here, I have reviewed the visual specialisations of predatory and scavenging diurnal raptors, focusing on (1) the anatomy of the eye a

Measurements and analysis of primary ship waves in the Stockholm Archipelago, Sweden

Primary ship waves generated by conventional marine vessels were investigated in the Furusund fairway located in the Stockholm archipelago, Sweden. Continuous water level measurements at two locations in the fairway were analyzed. In total, 466 such events were extracted during two months of measurements. The collected data were used to evaluate 13 existing predictive equations for drawdown height

Datafication as a Trend for Journalism : a Journalist’s Perspective

The datafication of journalism creates new demands on journalists. The set of skills and the daily work in the newsroom have changed the profession where traditional values might still be present but are challenged by how data is received, constructed and analyzed. This impacts how journalism is being produced; data contributes to the reporting and provides opportunities on how to conduct research

Automated orientation of water molecules in neutron crystallographic structures of proteins

The structure and function of proteins are strongly affected by the surrounding solvent water, for example through hydrogen bonds and the hydrophobic effect. These interactions depend not only on the position, but also on the orientation, of the water molecules around the protein. Therefore, it is often vital to know the detailed orientations of the surrounding ordered water molecules. Such inform

Impact of longer term phosphorus control on cardiovascular mortality in hemodialysis patients using an area under the curve approach : results from the DOPPS

BACKGROUND: Serial assessment of phosphorus is currently recommended by the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines, but its additional value versus a single measurement is uncertain. METHODS: We studied data from 17 414 HD patients in the Dialysis Outcomes and Practice Patterns Study, a prospective cohort study, and calculated the area under the curve (AUC) by multiplying the

Optimal Design of a High-Voltage DC/DC Converter for the 11.5-MW/115-kV ESS Long-Pulse Modulator

The stacked multilevel (SML) klystron modulator topology has been suggested as an alternative to conventional pulse transformer-based topologies in an attempt to improve output pulse performance and reduce system size for long-pulse applications. In this topology, a power converter chain including a high-frequency transformer generates the output pulse in a pulse modulation/demodulation scheme, el

Inhibition of LTβR signalling activates WNT-induced regeneration in lung

Lymphotoxin β-receptor (LTβR) signalling promotes lymphoid neogenesis and the development of tertiary lymphoid structures1,2, which are associated with severe chronic inflammatory diseases that span several organ systems3-6. How LTβR signalling drives chronic tissue damage particularly in the lung, the mechanism(s) that regulate this process, and whether LTβR blockade might be of therapeutic value

Consumer acceptance and value in use-oriented product-service systems : Lessons from Swedish consumer goods companies

In order to make our production and consumption systems more sustainable, there is a need to further explore and support novel business models with higher sustainability potential. Use-oriented product-service systems (u-PSS) are considered a promising alternative to traditional ownership-based business models, as they may result in lower environmental impacts. The presence of u-PSS in consumer go
