Quality of life in children and adolescents with respiratory allergy, assessed with a generic and disease specific instrument.

Introduction: Respiratory allergic disorders like rhinitis and asthma are common conditions that not only affect target organs, but complicate the daily life of affected children and adolescents. Objectives: The aim of this study was to investigate the QoL (Quality of Life) in children with grass pollen allergy in and out of grass pollen season. Methods: We used the Pediatric Allergic Disea

The importance of socioeconomic factors for compliance and outcome at screening for abdominal aortic aneurysm in 65-year-old men.

OBJECTIVE: To evaluate compliance with screening and prevalence of abdominal aortic aneurysm (AAA) in relation to background data regarding area-based socioeconomic status. METHODS: Our department annually invites 4300 65-year-old men from the city of Malmö and 15 neighboring municipalities to ultrasound AAA screening. In a cross-sectional cohort study, compliance and AAA prevalence among 8269 men

FoxJ1-expressing cells contribute to neurogenesis in forebrain of adult rats: Evidence from in vivo electroporation combined with piggyBac transposon.

Ependymal cells in the lateral ventricular wall are considered to be post-mitotic but can give rise to neuroblasts and astrocytes after stroke in adult mice due to insult-induced suppression of Notch signaling. The transcription factor FoxJ1, which has been used to characterize mouse ependymal cells, is also expressed by a subset of astrocytes. Cells expressing FoxJ1, which drives the expression o

Inflammation without neuronal death triggers striatal neurogenesis comparable to stroke.

Ischemic stroke triggers neurogenesis from neural stem/progenitor cells (NSPCs) in the subventricular zone (SVZ) and migration of newly formed neuroblasts towards the damaged striatum where they differentiate to mature neurons. Whether it is the injury per se or the associated inflammation that gives rise to this endogenous neurogenic response is unknown. Here we showed that inflammation without c

A latent neurogenic program in astrocytes regulated by Notch signaling in the mouse.

Neurogenesis is restricted in the adult mammalian brain; most neurons are neither exchanged during normal life nor replaced in pathological situations. We report that stroke elicits a latent neurogenic program in striatal astrocytes in mice. Notch1 signaling is reduced in astrocytes after stroke, and attenuated Notch1 signaling is necessary for neurogenesis by striatal astrocytes. Blocking Notch s

The assessment of serum-mediated phagocytosis of necrotic material by polymorphonuclear leukocytes to diagnose and predict the clinical features of systemic lupus erythematosus: an observational longitudinal study

Serum-mediated phagocytosis of antibody- and complement-opsonized necrotic cell material (NCM) by polymorphonuclear leukocytes can be quantified by using a flow cytometry–based assay. The phagocytosis of necrotic cell material (PNC) assay parallels the well-known lupus erythematosus cell test. In this study, we aimed to investigate the diagnostic accuracy of the assay and the relationship with cli

Copeptin predicts coronary artery disease cardiovascular and total mortality.

In a middle-aged population, it was recently shown that the stable vasopressin marker plasma copeptin (copeptin) predicts development of diabetes mellitus, diabetic heart disease and death. Here, it was hypothesised whether copeptin predicts a risk of coronary artery disease (CAD), and cardiovascular mortality in an older population.

Somatic cells with a heavy mitochondrial DNA mutational load render iPS cells with distinct differentiation defects.

It has become increasingly clear that several age-associated pathologies associate with mutations in the mitochondrial genome. Experimental modeling of such events has revealed that acquisition of mitochondrial DNA (mtDNA) damage can impair respiratory function and, as a consequence, can lead to widespread decline in cellular function. This includes premature aging syndromes. By taking advantage o

Expression analysis of pluripotency-associated genes in human fetal cortical and striatal neural stem cells during differentiation

In the field of developmental biology, there is compelling evidence for a network of activity of pluripotency and stem-associated genes comprising of Oct4, Nanog and nestin. During neurogenesis, the choice between enhancement versus suppression of transcriptional modulation of these identified genes determines the balance between self-renewal neural stem cells (NSC) and immature neuronal phenotype

Feasibility assessment of using oxygen-enhanced magnetic resonance imaging for evaluating the effect of pharmacological treatment in COPD.

Oxygen-enhanced MRI (OE-MRI) biomarkers have potential value in assessment of COPD, but need further evaluation before treatment-induced changes can be interpreted. The objective was to evaluate how OE-MRI parameters of regional ventilation and oxygen uptake respond to standard pharmacological interventions in COPD, and how the response compares to that of gold standard pulmonary function tests.

Developing dopaminergic cell therapy for Parkinson's disease-give up or move forward?

Despite 3 decades of basic and clinical studies, there is still no dopaminergic cell therapy for Parkinson's disease. Several arguments have been put forward why this approach, so far tested with transplantation of human fetal mesencephalic dopamine-rich tissue, will never be of clinical use and should be abandoned: (1) Lack of efficacy in 2 sham surgery-controlled trials; (2) occurrence of troubl

Genetic profiles distinguish different types of hereditary ovarian cancer.

Heredity represents the strongest risk factor for ovarian cancer with disease predisposing mutations identified in 15% of the tumors. With the aim to identify genetic classifiers for hereditary ovarian cancer, we profiled hereditary ovarian cancers linked to the hereditary breast and ovarian cancer (HBOC) syndrome and the hereditary non-polyposis colorectal cancer (HNPCC) syndrome. Genome-wide arr

Embryonic Stem Cell-Derived Neural Stem Cells Fuse with Microglia and Mature Neurons.

Transplantation of neural stem cells (NSCs) is a novel strategy to restore function in the diseased brain, acting through multiple mechanisms, e.g., neuronal replacement, neuroprotection and modulation of inflammation. Whether transplanted NSCs can operate by fusing with microglial cells or mature neurons is largely unknown. Here we have studied the interaction of a mouse embryonic stem cell-deriv
