Clinical and epidemiological features of Heart-Hand Syndrome : A hospital-based study in China

Heart-hand syndrome (HHS) is a clinically and genetically heterogeneous disorder characterized by the co-occurrence of a congenital cardiac disease and an upper limb malformation. This study revealed the clinical and epidemiological features of HHS in China. The study was based on patients with congenital upper limb malformation treated in Beijing Ji Shui Tan hospital from October 1st, 2013 to Oct

The effects of low pH on the properties of protochlorophyllide oxidoreductase and the organization of prolamellar bodies of maize (Zea mays)

Prolamellar bodies (PLB) contain two photochemically active forms of the enzyme protochlorophyllide oxidoreductase POR-PChlide640 and POR-PChlide650 (the spectral forms of POR-Chlide complexes with absorption maxima at the indicated wavelengths). Resuspension of maize PLB in media with a pH below 6.8 leads to a rapid conversion of POR-PChlide650 to POR-PChlide640 and a dramatic re-organization of

Four evolutionary trajectories underlie genetic intratumoral variation in childhood cancer

A major challenge to personalized oncology is that driver mutations vary among cancer cells inhabiting the same tumor. Whether this reflects principally disparate patterns of Darwinian evolution in different tumor regions has remained unexplored1–5. We mapped the prevalence of genetically distinct clones over 250 regions in 54 childhood cancers. This showed that primary tumors can simultaneously f

Carbon uptake and water use in woodlands and forests in southern Australia during an extreme heat wave event in the "angry Summer" of 2012/2013

As a result of climate change warmer temperatures are projected through the 21st century and are already increasing above modelled predictions. Apart from increases in the mean, warm/hot temperature extremes are expected to become more prevalent in the future, along with an increase in the frequency of droughts. It is crucial to better understand the response of terrestrial ecosystems to such temp

Why Local Shopping Streets Matter : A visual ethnographic study of shopping activities

Retail and cities have had a long and intertwined history together. Since the beginning of first cities established, being a hub for commercial exchange has been one of the main elements what makes a city (Söderlind, 2011). Nevertheless, since 1980s, there have been some substantial shifts at the global scale regarding the organization of retail, and in turn, its spatial manifestations in the citi

The effect of preparation for lumbar puncture on children undergoing chemotherapy

At the University Hospital in Lund, Sweden, a preparation program was developed for children undergoing lumbar punctures (LPs) during chemotherapy for leukemia or lymphoma. Subsequently, a study was initiated to determine whether a preparation program for children prior (o treatment would reduce their anxiety and improve their cooperation. This study also was undertaken to examine whether reinforcAt the University Hospital in Lund, Sweden, a preparation program was developed for children undergoing lumbar punctures (LPs) during chemotherapy for leukemia or lymphoma.

Chlorosis during nitrogen starvation is altered by carbon dioxide and temperature status and is mediated by the ClpP1 protease in Synechococcus elongatus

The interactive effects of inorganic carbon status, temperature and light on chlorosis induced by nitrogen deficiency, and the roles of Clp proteases in this process were investigated. In wild-type cultures grown in high or ambient CO(2), following transfer to media lacking combined nitrogen, phycocyanin per cell dropped primarily through dilution of the pigment through cell division, and also suf

On the interpretation of gerundival null subjects and the theory of control

It is generally known that gerunds can have a null subject (NS) that takes the preceding clause as its antecedent. Given certain restrictions independently argued for in the literature, the NS in question cannot be pro, neither can it be maintained that such gerunds have the status of relative clauses. Therefore, the subject in question must be analysed as PRO, which entails that the theoretical s

Comparison of Preparation and Narcotic-Sedative Premedication in Children Undergoing Surgery

A psychological preparation program was developed for use prior to emergency surgery in children. The purpose of this study was to test the hypothesis that provision of specific information prior to an emergency operation would reduce the need for premedication to control anxiety and stress. Children were randomly assigned to either a verbally prepared group given narcotic-sedative premedication (

Monitoring boreal forest biomass and carbon storage change by integrating airborne laser scanning, biometry and eddy covariance data

This study presents a comparison and integration of three methods commonly used to estimate the amount of forest ecosystem carbon (C) available for storage. In particular, we examine the representation of living above- and below-ground biomass change (net accumulation) using plot-level biometry and repeat airborne laser scanning (ALS) of three dimensional forest plot structure. These are compared

Field validation of radar systems for monitoring bird migration

Advances in information technology are increasing the use of radar as a tool to investigate and monitor bird migration movements. We set up a field campaign to compare and validate outputs from different radar systems. Here we compare the pattern of nocturnal bird migration movements recorded by four different radar systems at a site in southern Sweden. Within the range of the weather radar (WR) Ä

Re-structuring of marine communities exposed to environmental change : A global study on the interactive effects of species and functional richness

Species richness is the most commonly used but controversial biodiversity metric in studies on aspects of community stability such as structural composition or productivity. The apparent ambiguity of theoretical and experimental findings may in part be due to experimental shortcomings and/or heterogeneity of scales and methods in earlier studies. This has led to an urgent call for improved and mor

Novel form of ClpB/HSP100 protein in the cyanobacterium Synechococcus

Synechococcus sp. strain PCC 7942 has a second clpB gene that encodes a 97-kDa protein with novel features. ClpBII is the first ClpB not induced by heat shock or other stresses; it is instead an essential, constitutive protein. ClpBII is unable to complement ClpBI function for acquired thermotolerance. No truncated ClpBII version is normally produced, unlike other bacterial forms, while ectopic sy

Production of the artemisinin precursor amorpha-4,11-diene by engineered Saccharomyces cerevisiae

The gene encoding for amorpha-4,11-diene synthase from Artemisia annua was transformed into yeast Saccharomyces cerevisiae in two fundamentally different ways. First, the gene was subcloned into the galactose-inducible, high-copy number yeast expression vector pYeDP60 and used to transform the Saccharomyces cerevisiae strain CEN.PK113-5D. Secondly, amorpha-4,11-diene synthase gene, regulated by th

Radical pericardiectomy for chronic constrictive pericarditis

Background: We studied the impact of radical pericardiectomy on early and long-term patient survival, postoperative New York Heart Association (NYHA) functional class, and left ventricular ejection fraction in patients with chronic constrictive pericarditis compared to a sub-total pericardiectomy. Methods: From 1991 to 2016, 41 patients underwent pericardiectomy for chronic constrictive pericardit

Stadsbor : urbana aktörer, subjektiv interaktionism och social neurovetenskap i tidigmedeltidens Sigtuna och Nyköping

In Swedish historical archaeology, studies of towns have diverged from definition to deconstruction. In landscape studies the existence of occasional similar expressions of power in rural contexts as in towns is stressed. Another observation is that towns can display vague forms of urbanity, with lack of dense settlement and varied economy, as well as showing agrarian affiliations. A focus on sing

Usefulness of Electrocardiographic Left Atrial Abnormality to Predict Response to Cardiac Resynchronization Therapy in Patients With Mild Heart Failure and Left Bundle Branch Block (a Multicenter Automatic Defibrillator Implantation Trial with Cardiac Resynchronization Therapy Substudy)

Cardiac resynchronization therapy (CRT) has proven prognostic benefits in patients with heart failure (HF) with left bundle branch block (LBBB) QRS morphology. Electrocardiographic left atrial (LA) abnormality has been proposed as a noninvasive marker of atrial remodeling. We aimed to assess the impact of electrocardiographic LA abnormality for prognosis in patients with HF treated with CRT. Basel

Geospatial data integration and visualisation using Linked Data

Geospatial data are increasingly available nowadays, and this leads to more analyses and visualisation of geospatial data from several sources. To enable this, we need homogenous data as well as proper integration methods. Geospatial data integration has been a longstanding research topic for decades, and this paper discusses the utilisation of Linked Data technology stack to alleviate the geospat

The neutrophil-mobilizing cytokine interleukin-26 in the airways of long-term tobacco smokers

Long-term tobacco smokers with chronic obstructive pulmonary disease (COPD) or chronic bronchitis display an excessive accumulation of neutrophils in the airways; an inflammation that responds poorly to established therapy. Thus, there is a need to identify new molecular targets for the development of effective therapy. Here, we hypothesized that the neutrophil-mobilizing cytokine interleukin (IL)
