Toward the equilibrium and kinetics of amyloid peptide self-assembly

Several devastating human diseases are linked to peptide self-assembly, but our understanding their onset and progression is not settled. This is a sign of the complexity of the aggregation process, which is prevented, catalyzed, or retarded by numerous factors in body fluids and cells, varying in time and space. Biophysical studies of pure peptide solutions contribute insights into the underlying

Dynamical evolution of two planet systems into the white dwarf phase

In this contribution we present some preliminary results on the dynamical evolution of two planet systems around stellar hosts evolving from the main sequence to the white dwarf phase. The aim is to study the instabilities triggered by stellar evolution that may bring planets onto the stellar surface or produce planetary scale collisions (hence debris) that could explain the metallic atmospheric p

Disseminated tumour cells from the bone marrow of early breast cancer patients : Results from an international pooled analysis

Purpose: Presence of disseminated tumour cells (DTCs) in the bone marrow (BM) has been described as a surrogate of residual disease in patients with early breast cancer (EBC). PADDY (Pooled Analysis of DTC Detection in Early Breast Cancer) is a large international analysis of pooled data that aimed to assess the prognostic impact of DTCs in patients with EBC. Experimental design: Individual patien

A Guide for Using Flight Simulators to Study the Sensory Basis of Long-Distance Migration in Insects

Studying the routes flown by long-distance migratory insects comes with the obvious challenge that the animal’s body size and weight is comparably low. This makes it difficult to attach relatively heavy transmitters to these insects in order to monitor their migratory routes (as has been done for instance in several species of migratory birds. However, the rather delicate anatomy of insects can be

A comparative study of the effects of the 1872 storm and coastal flood risk management in denmark, germany, and sweden

From November 12th to 13th in 1872, an extreme coastal flood event occurred in the south Baltic Sea. An unusual combination of winds created a storm surge reaching up to 3.5 m above mean sea level, which is more than a meter higher than all other observations over the past 200 years. On the Danish, German, and Swedish coasts, about 300 people lost their lives. The consequences of the storm in Denm

Locating potential sources of capacity and vulnerability in geographically remote areas : Reflections based on three case studies

The relationship between geographical and social forms of remoteness and the concepts of vulnerability and capacity remains unclear. Recognising that capacities and vulnerabilities tend to co-exist in a population, the article assumes that the dynamics between these concepts are situational. In this article we draw on three cases to analyse the issue. An Arctic case study provides insight on remot

Homeostatic swimming of zooplankton upon crowding : The case of the copepod Centropages typicus

Crowding has a major impact on the dynamics of many material and biological systems, inducing effects as diverse as glassy dynamics and swarming. While this issue has been deeply investigated for a variety of living organisms, more research remains to be done on the effect of crowding on the behaviour of copepods, the most abundant metazoans on Earth. To this aim, we experimentally investigate the

Decadal-scale dune evolution at Duck, North Carolina

Analysis of a 13-year long, high-resolution data series on beach profiles, surveyed from 1981 to 1993 by the Army Field Research Facility (FRF) at Duck, North Carolina, in the United States, was analyzed in order to understand the temporal and spatial characteristics of the dune response. Various statistical methods were employed in this analysis. The profile survey data set was analyzed with rega

Outcome of Repeat Venoarterial Extracorporeal Membrane Oxygenation in Postcardiotomy Cardiogenic Shock

Objective: Data on patients requiring a second run of venoarterial extracorporeal membrane oxygenation (VA-ECMO) support in patients affected by postcardiotomy cardiogenic shock (PCS) are very limited. The authors aimed to investigate the effect of a second run of VA-ECMO on PCS patient survival. Design: Retrospective analysis of an international registry. Setting: Multicenter study, tertiary univ

Summary . Pied Flycatchers Ficedula hypoleuca are known to be victims of nest killings in contexts of competition for nest boxes. However, there is only anecdotal information on their opposite role as perpetrators of nest takeovers and occasional killings of other songbirds. Over 31 years we examined whether competition with Great Tits Parus major over nest box ownership is a significant source of

The social worker-client relationship in the digital era: : a configurative literature review

Relationen mellan socialarbetare och klienter beskrivs som central för socialt arbete men är ett brett och mångtydigt begrepp. Idag stärks och utmanas relationen genom digitalisering. Syftet med denna konfigurativa litteraturöversikt är att förstå hur forskning om socialt arbete mellan 2015 och 2020 beskriver och analyserar digitaliseringens betydelse för relationen mellan socialarbetare och klien

Tracking the Adoption of Early Pottery Traditions into Maritime Northeast Asia : Emerging Insights and New Questions

Understanding the emergence and development of coastal adaptations is a central theme in the archaeology of Maritime Northeast Asia. The capacity to harvest, store and share aquatic resources offered a novel economic strategy that could support greater sedentism and new forms of social life. In turn, growing reliance on the exploitation of rich coastal resources wouldhave generated powerful incent

Exceptional preservation of reidite in the Rochechouart impact structure, France: New insights into shock deformation and phase transition of zircon

Reidite, the high-pressure zircon (ZrSiO4) polymorph, is a diagnostic indicator of impact events. Natural records of reidite are, however, scarce, occurring mainly as micrometer-sized lamellae, granules, and dendrites. Here, we present a unique sequence of shocked zircon grains found within a clast from the Chassenon suevitic breccia (shock stage III) from the ˜200 Ma, 20–50 km wide Rochechouart i

The neurological and neuropsychiatric spectrum of adults with late-treated phenylketonuria

Introduction: Phenylketonuria (PKU) is a rare, treatable inborn error of metabolism with frequent neurological and neuropsychiatric complications, especially in undiagnosed or insufficiently treated individuals. Given the wide range of clinical presentations and the importance of treatment implications, we here delineate the neurological and neuropsychiatric symptom spectrum in a large cohort of p
