Evolution of sex chromosomes in Sylvioidea songbirds
Sex chromosomes were discovered more than 100 years ago. They have been studied intensely from a theoretical perspective since then, giving rise to a large body of testable predictions about their evolution from autosomes. A common feature of sex chromosomes is recombination suppression between the sex chromosome copies (X and Y in male heterogametic systems, or Z and W in female heterogametic sys

Cervical cancer among Swedish women with drug use disorders : A nationwide epidemiological study
Background/Aim: Cervical cancer incidence and mortality has decreased after introduction of national screening in Sweden, but women with drug use disorders (DUD) are less likely to participate in screening programs. We aimed to investigate cervical cancer incidence and mortality among women with DUD compared to the general female population in Sweden. Methods: We conducted a cohort study based on
Introduction to 2018 special issue: Ontological (in)security in the European Union
The European Union (EU) faces many crises and risks to its security and existence. While few of them threaten the lives of EU citizens, they all create a sense of anxiety and insecurity about the future for many ordinary Europeans. Amongst these crises are the more obvious challenges of sovereign debt and fiscal austerity; refugees from conflicts in Afghanistan, Iraq, and Syria; and the rise of po

A LC–MS/MS method for the quantification of caffeine, betamethasone, clonidine and furosemide in cerebrospinal fluid of preterm infants
Background: Newborns, admitted to the Neonatal Intensive Care Unit (NICU), are exposed to a large number of medications, the majority of which are not labeled for use in infants, especially in preterm newborns, because clinical trials on their benefits and harms are lacking. There is a huge gap in knowledge on pharmacokinetic (PK) data in sick preterm infants, including that of drug penetration to

A patterning-free approach for growth of free-standing graphene nanoribbons using step-bunched facets of off-oriented 4H-SiC(0 0 0 1) epilayers
The tunable electronic structure of graphene nanoribbons (GNRs) has attracted much attention due to the great potential in nanoscale electronic applications. Most methods to produce GNRs rely on the lithographic process, which suffers from the process-induced disorder in the graphene and scalability issues. Here, we demonstrate a novel approach to directly grow free-standing GNRs on step-bunched f
Interleukin-1 beta neutralization attenuates traumatic brain injury-induced microglia activation and neuronal changes in the globus pallidus
Traumatic brain injury (TBI) increases the risk of delayed neurodegenerative processes, including Parkinson’s disease (PD). Interleukin-1beta (IL-1β), a key pro-inflammatory cytokine, may promote secondary injury development after TBI. Conversely, neutralizing IL-1β was found to improve functional recovery following experimental TBI. However, the mechanisms underlying the behavioral improvements o

Dynamic effects of institutions on firm-level exports
The gap between theoretically predicted trade patterns and actual trade suggests that our understanding of what shapes trade patterns is incomplete. Institutional barriers may be one factor behind this gap, and recent research suggests that institutions are a greater obstacle to trade than tariffs. Using detailed firm-level data, we analyze how institutional quality in recipient countries affects
Room temperature multiferroic PZTFT thin films
Multiferroic materials have shown significant potential for next generation nanoelectronic and multifunctional devices due to their coexistent order parameters and versatile tunabilities. Nevertheless, the selectivity of the room temperature multiferroics is extremely limited. In this manner, single-phase solid-solution-type multiferroics that are composed by distinct oxides exhibiting either ferr
