Dynamics of critical fluctuations : Theory – phenomenology – heavy-ion collisions
This report summarizes the presentations and discussions during the Rapid Reaction Task Force “Dynamics of critical fluctuations: Theory – phenomenology – heavy-ion collisions”, which was organized by the ExtreMe Matter Institute EMMI and held at GSI, Darmstadt, Germany in April 2019. We address the current understanding of the dynamics of critical fluctuations in QCD and their measurement in heav

Effect of temperature on the association behavior in aqueous mixtures of an oppositely charged amphiphilic block copolymer and bile salt
The association in aqueous mixtures of a thermoresponsive cationic diblock copolymer composed of poly(N-isopropylacrylamide) (PNIPAM) and poly(3-acrylamidopropyl)-trimethylammonium-chloride (PAMPTMA(+)) and the oppositely charged bile salt sodium deoxycholate (NaDC) is investigated at different compositions by light and X-ray scattering, calorimetry, and electrophoretic mobility measurements.

Social class and fertility: A Long-run analysis of Southern Sweden, 1922–2015
This paper examines social class differences in fertility, using longitudinal micro-level data for a regionalsample in Sweden, 1922–2015. Using discrete-time event history models, we estimated the associationbetween social class and parity-specific duration to next birth, adjusting for household income in separatemodels. Social class was associated with fertility quite independently from income an
Increased expression levels of inflammatory cytokines and adhesion molecules in lipopolysaccharide‑induced acute inflammatory apoM‑/‑ mice
apolipoproteinM(apoM)mayserveaprotectiverole inthedevelopmentofinflammation.Nuclearfactor‑κB(nF-κB) and its downstream factors (including a number of inflammatory cytokines and adhesion molecules) are essential for the regulation of inflammatory processes. In the present study, the importance of apoM in lipopolysaccharide (LPS)‑induced acute inflammation and its potential underlying mechanisms, we
Farmer-herder conflicts, tenure insecurity and farmer’s investment decisions in Agogo, Ghana
Owing to climate change, population growth and tenurial changes, the past decade has witnessed high interest among migrant and settler pastoralist groups in thevegetal-rich customary lands of the Agogo Traditional Area. This has resulted in lease grants of large land areas to pastoralists by traditional authorities and usufructfamilies, for reasons of ensuring optimum use and gaining the highest r
Derivation of human iPS cell lines from monozygotic twins in defined and xeno free conditions
Human induced pluripotent stem (hiPS) cell lines CTRL-9-II and CTRL-10-I were derived from healthy monozygotic twin donors using non-integrating RNA based Sendai virus reprogramming and cultured in a xeno-free chemically defined condition. The established hiPS cell lines, CTRL-9-II and CTRL-10-I, are karyotypically normal, free from reprogramming vectors, display endogenously expression of pluripo
Generation of human iPS cell line CTL07-II from human fibroblasts, under defined and xeno-free conditions
CTL07-II is a healthy feeder-free and characterized human induced pluripotent stem (iPS) cell line. Cultured under xeno-free and defined conditions. The line is generated from healthy human fibroblasts with non-integrating Sendai virus vectors encoding the four Yamanaka factors, OCT4, SOX2, KLF4 and cMYC. The generated iPS cells are free from reprogramming vectors and their purity, karyotypic stab
Induction of sensory neurons from neuroepithelial stem cells by the ISX9 small molecule
Hearing impairment most often involves loss of sensory hair cells and auditory neurons. As this loss is permanent in humans, a cell therapy approach has been suggested to replace damaged cells. It is thus of interest to generate lineage restricted progenitor cells appropriate for cell based therapies. Human long-term self-renewing neuroepithelial stem (lt-NES) cell lines exhibit in vitro a develop
Glucocorticoids alter neuronal differentiation of human neuroepithelial-like cells by inducing long-lasting changes in the reactive oxygen species balance
Prenatal exposure to excess glucocorticoid has been shown to have adverse effects on the developing nervous system that may lead to alterations of fetal and adult neurogenesis, resulting in behavioral changes. In addition, an imbalance of the redox state, with an increased susceptibility to oxidative stress, has been observed in rodent neural stem cells exposed to the synthetic glucocorticoid anal
Spider silk for xeno-free long-term self-renewal and differentiation of human pluripotent stem cells
Human pluripotent stem cells (hPSCs) can undergo unlimited self-renewal and have the capacity to differentiate into all somatic cell types, and are therefore an ideal source for the generation of cells and tissues for research and therapy. To realize this potential, defined cell culture systems that allow expansion of hPSCs and subsequent controlled differentiation, ideally in an implantable three
The Roots of Autism and ADHD Twin Study in Sweden (RATSS)
Neurodevelopmental disorders affect a substantial minority of the general population. Their origins are still largely unknown, but a complex interplay of genetic and environmental factors causing disturbances of the central nervous system's maturation and a variety of higher cognitive skills is presumed. Only limited research of rather small sample size and narrow scope has been conducted in neuro
A 3D Alzheimer's disease culture model and the induction of P21-activated kinase mediated sensing in iPSC derived neurons
The recent progress in stem cell techniques has broadened the horizon for in vitro disease modeling. For desired in vivo like phenotypes, not only correct cell type specification will be critical, the microenvironmental context will be essential to achieve relevant responses. We demonstrate how a three dimensional (3D) culture of stem cell derived neurons can induce in vivo like responses related
Stem cells expanded from the human embryonic hindbrain stably retain regional specification and high neurogenic potency
Stem cell lines that faithfully maintain the regional identity and developmental potency of progenitors in the human brain would create new opportunities in developmental neurobiology and provide a resource for generating specialized human neurons. However, to date, neural progenitor cultures derived from the human brain have either been short-lived or exhibit restricted, predominantly glial, diff
Automated large-scale culture and medium-throughput chemical screen for modulators of proliferation and viability of human induced pluripotent stem cell-derived neuroepithelial-like stem cells
The aim of this study was to demonstrate proof-of-concept feasibility for the use of human neural stem cells (NSCs) for high-throughput screening (HTS) applications. For this study, an adherent human induced pluripotent stem (iPS) cell-derived long-term, self-renewing, neuroepithelial-like stem (lt-NES) cell line was selected as a representative NSC. Here, we describe the automated large-scale ser
Generation of anti-Notch antibodies and their application in blocking Notch signalling in neural stem cells
Notch signalling occurs via direct cell-cell interactions and plays an important role in linking the fates of neighbouring cells. There are four different mammalian Notch receptors that can be activated by five cell surface ligands. The ability to inhibit specific Notch receptors would help identify the roles of individual family members and potentially provide a means to study and control cell di
Treatment of a mouse model of spinal cord injury by transplantation of human induced pluripotent stem cell-derived long-term self-renewing neuroepithelial-like stem cells
Because of their ability to self-renew, to differentiate into multiple lineages, and to migrate toward a damaged site, neural stem cells (NSCs), which can be derived from various sources such as fetal tissues and embryonic stem cells, are currently considered to be promising components of cell replacement strategies aimed at treating injuries of the central nervous system, including the spinal cor
Capture of neuroepithelial-like stem cells from pluripotent stem cells provides a versatile system for in vitro production of human neurons
Human embryonic stem cells (hESC) and induced pluripotent stem cells (iPSC) provide new prospects for studying human neurodevelopment and modeling neurological disease. In particular, iPSC-derived neural cells permit a direct comparison of disease-relevant molecular pathways in neurons and glia derived from patients and healthy individuals. A prerequisite for such comparative studies are robust pr
