Single-Cell Analysis Identifies Distinct Stages of Human Endothelial-to-Hematopoietic Transition

During development, hematopoietic cells originate from endothelium in a process known as endothelial-to-hematopoietic transition (EHT). To study human EHT, we coupled flow cytometry and single-cell transcriptional analyses of human pluripotent stem cell-derived CD34(+) cells. The resulting transcriptional hierarchy showed a continuum of endothelial and hematopoietic signatures. At the interface of

Multilingual Spaces : Language Practices in English Classrooms. A Project Presentation

This paper presents a project that recently received funding from the Swedish Research Council. Data collection will begin in autumn 2017, focusing on language practices in multilingual English classroom spaces in Swedish secondary schools. While English is the normal medium of instruction in lessons, research in bilingual educational settings shows that judicious switches between pupils’ mother t

Development and verification of a pharmacokinetic model to optimize physiologic replacement of rhIGF-1/rhIGFBP-3 in preterm infants

Background:rhIGF-1/rhIGFBP-3 is being investigated for prevention of retinopathy of prematurity in extremely preterm infants.Methods:A population pharmacokinetic model was developed using data from phase I/II (Sections A-C) trials of rhIGF-1/rhIGFBP-3 and additional studies in preterm infants to predict optimal dosing to establish/maintain serum IGF-1 within physiological intrauterine levels. In S

Molecular adaptations of striatal spiny projection neurons during levodopa-induced dyskinesia

Levodopa treatment is the major pharmacotherapy for Parkinson's disease. However, almost all patients receiving levodopa eventually develop debilitating involuntary movements (dyskinesia). Although it is known that striatal spiny projection neurons (SPNs) are involved in the genesis of this movement disorder, the molecular basis of dyskinesia is not understood. In this study, we identify distinct

Preclinical models of levodopa-induced dyskinesia

L -DOPA-induced dyskinesia (LID) represents one of the major limitations in the current pharmacotherapy of Parkinson's disease (PD) and affects the majority of PD patients. Animal models are the most important preclinical tool for molecular investigations of LID mechanisms and therapeutic targets. Over the last two decades, models of LID have been developed in both nonhuman primate and rodent spec

Crystal structure of AcrB in complex with a single transmembrane subunit reveals another twist

Bacterial drug resistance is a serious concern for human health. Multidrug efflux pumps export a broad variety of substrates out of the cell and thereby convey resistance to the host. In Escherichia coli, the AcrB:AcrA:TolC efflux complex forms a principal transporter for which structures of the individual component proteins have been determined in isolation. Here, we present the X-ray structure o

Optimised treatment of hip fractures

Fractures of the proximal part of the femur, hip fractures, are common and costly. The number of hip fractures has increased in all western countries during recent decades. This has occurred mainly because of an increase in the number of elderly people and also due to an increase in the risk for hip fracture among the oldest persons. Due to an increase in ageing population all over the world there

Longitudinal 10-year changes in dietary intake and associations with cardio-metabolic risk factors in the Northern Sweden Health and Disease Study

Background: Dietary risks today constitute the largest proportion of disability-adjusted life years (DALYs) globally and in Sweden. An increasing number of people today consume highly processed foods high in saturated fat, refined sugar and salt and low in dietary fiber, vitamins and minerals. It is important that dietary trends over time are monitored to predict changes in disease risk. Methods:

Can redistribution by means of a progressive labor income-taxation transfer system increase financial stability?

We present a model featuring heterogeneous households with a conspicuous consumptionmotive, in which inequality can decrease financial stability, and relate this behavior to the recent financial crisis in theUSA. A natural policy conclusion would be to combat income inequality jointly with financial instability by means of a progressive system of taxes and transfers. We investigate this for the ca

The relationship between caloric response, oculomotor dysfunction and size of cerebello-pontine angle tumours

Seventy-nine consecutive patients, 70 patients with acoustic neurinomas (ACN) and 9 patients with cerebello-pontine angle tumours of other etiology (o-CPA) were analysed with respect to tumour size and the result of the caloric and oculomotor tests. The size of the tumour was judged by the largest diameter calculated from the computerized tomography. A highly significant linear relationship betwee

A short history of chromosome rearrangements and gene fusions in cancer

The molecular characterization of recurrent chromosome aberrations in the early 1980s laid the foundation for gene fusion detection in cancer. This approach remained the unrivalled method to identify fusion genes for a quarter of a century and led to the detection of more than 700 neoplasia-associated fusion genes. The advancement of deep sequencing in the mid-2000s revolutionized the search for c

Future and potential spending on health 2015-40 : development assistance for health, and government, prepaid private, and out-of-pocket health spending in 184 countries

BACKGROUND: The amount of resources, particularly prepaid resources, available for health can affect access to health care and health outcomes. Although health spending tends to increase with economic development, tremendous variation exists among health financing systems. Estimates of future spending can be beneficial for policy makers and planners, and can identify financing gaps. In this study,

Evolution and patterns of global health financing 1995-2014 : development assistance for health, and government, prepaid private, and out-of-pocket health spending in 184 countries

BACKGROUND: An adequate amount of prepaid resources for health is important to ensure access to health services and for the pursuit of universal health coverage. Previous studies on global health financing have described the relationship between economic development and health financing. In this study, we further explore global health financing trends and examine how the sources of funds used, typ

Improving outcomes of short peripheral vascular access in oncology and chemotherapy administration

A short peripheral intravenous catheter or cannula (PIVC) is frequently used to deliver chemotherapy in oncology practice. Although safe and easy to insert, PIVCs do fail, leading to personal discomfort for patients and adding substantially to treatment costs. As the procedure of peripheral catheterization is invasive, there is a need for greater consistency in the choice, insertion and management

Improvement of identification methods for honeybee specific Lactic Acid Bacteria; Future approaches

Honeybees face many parasites and pathogens and consequently rely on a diverse set of individual and group-level defenses to prevent disease. The crop microbiota of Apis mellifera, composed of 13 Lactic Acid Bacterial (LAB) species within the genera Lactobacillus and Bifidobacterium, form a beneficial symbiotic relationship with each other and the honeybee to protect their niche and their host. Po

Postural control in blinds and in Usher's syndrome

The postural control mechanisms were evaluated in 10 blinds and in 10 subjects with Usher's syndrome. The results were compared with 27 age matched healthy volunteers. In visual conditions the subjects with Usher's syndrome performed worse, but in nonvisual condition they performed equally well as the controls. The results were the same irrespective of whether the tests were performed on a rigid s
