Madelung A, Bzorek M, Bondo H, Zetterberg E, Bjerrum O W, Hasselbalch H C, Scheding S & Ralfkiaer E (2012) Histopathology A novel immunohistochemical sequential multi-labelling and erasing technique enables epitope characterization of bone marrow pericytes in primary myelofibrosis Aim: In Philadelphia (Ph)-negative chronic myeloproliferative neoplasms, increased microvascular density, bizarre
PURPOSE: Whether childhood adrenocortical tumors (ACTs), choroid plexus tumors (CPTs), and rhabdomyosarcoma (RMS) are early manifestation of Li-Fraumeni syndrome (LFS) is uncertain. In this study, we evaluated the frequency of germline TP53 mutations and family history in a population-based series of patients. PATIENTS AND METHODS: We identified children (≤18 years) diagnosed between 1958 and
Stroke-induced neurogenesis originates from a neural stem cell (NSC) niche in subventricular zone (SVZ). In mice, NSCs are concentrated in a so-called "neurogenic spot" in the lateral angle area of SVZ. We aimed to identify the "neurogenic spot" in the rat SVZ and to characterize the cellular changes in the ependymal cell compartment in this area at different time points after middle cerebral arte
Rett syndrome (RTT) is caused by loss-of-function mutations in the X-linked gene MECP2 coding for methyl CpG-binding protein 2 (MeCP2). This protein can act as transcriptional repressor and we showed in a previous study that glucocorticoid-inducible genes are up-regulated in a RTT mouse model and that these genes are direct MeCP2 targets. Here, we report that pharmacological intervention with the
Neural stem cells (NSCs) have attracted major research interest due to their potential use in cell replacement therapy. In patients, human cells are the preferred choice, one source of human NSCs being the brain of fetuses. The aims of the present study were to explore the long-term differentiation, mobility and viability of NSCs derived from the human fetal striatum in response to intracerebral i
BACKGROUND: Allogeneic stem cell transplantation (alloSCT) reduces relapse rates in acute leukemia, but outcome is hampered by toxicity. Population-based data avoid patient selection and may therefore substitute for lack of randomized trials. METHODS: We evaluated alloSCT rates within the Swedish Acute Leukemia Registry, including 3899 adult patients diagnosed from 1997 through 2006 with a coverag
Breathlessness is a major cause of suffering and distress and little is known about the trajectory of breathlessness near death.
Patient-reported outcomes (PROs), such as symptoms and perceived health status, are essential in chronic obstructive pulmonary disease (COPD) for determining disease severity, impact on daily life, effect of treatment and recovery from exacerbations. This field has evolved rapidly and there are a plethora of instruments assessing different PROs. Here, we aim to provide an understanding of the conc
Leukotrienes are involved in airway inflammation, and are believed to stimulate airway remodeling in asthma. The aim of the project was to investigate the expression of leukotriene receptors in peripheral and central airway fibroblasts. Peripheral and central airway fibroblasts, from asthmatics and healthy controls, were investigated for the amount of cysteinyl-leukotriene receptors (CysLT(1) and
Background: A woman's refusal or request for a cesarean section can be a problem for midwives and obstetricians working in maternity units. The objective of this study was to describe the attitudes of midwives in Sweden toward the obstetrician's decision making in relation to a woman's refusal of an emergency cesarean section and to a woman's request for a cesarean section without a medical indica
Neural stem cells are defined as cells that either gives rise to or derives from the cells of the central nervous system and have the unique properties of stem cells, i.e. self-renewal and multipotentiality. One of the widely used methods of expanding neural stem cells under culture conditions is based on the capacity of these cells to divide continuously when cultured in serum-free medium supplem
PURPOSE: This study was conducted to examine the effects of 5-HT on extracellular signal-regulated kinase 1/2 (Erk1/2) and Akt pathways in prostate cancer (PC) cells. METHODS: PC cell lines PC-3, Du145, and LNCaP stimulated with 5-HT in the presence of MEK or PI3K inhibitors and 5-HT receptor subtype 1A antagonist were analyzed by Western blotting and immunofluorescence. The proliferation assay Br
PURPOSE: For primary melanomas, tumor thickness, mitotic rate and ulceration are well-laid cornerstones of prognostication. However, a molecular exposition of melanoma aggressiveness is critically missing. We recently uncovered a four-class structure in metastatic melanoma that predicts outcome and informs biology. This raises the possibility that a molecular structure exists even in the early st
Violence against women is an increasing global phenomenon. Little is known about violence against foreign-born women, despite a possible increased concentration of risk factors in this group.
Characterization of directed differentiation of pluripotent stem cells towards therapeutically relevant cell types, including pancreatic beta-cells and hepatocytes, depends on molecular markers and assays that resolve the signature of individual cells. Pancreas and liver both have a common origin of anterior definitive endoderm (DE). Here, we differentiated human embryonic stem cells towards DE us
Smoking is an important cardiovascular risk factor and smoking cessation should be a primary target in secondary prevention after a myocardial infarction (MI).
BACKGROUND: Reports on trends in incidence and mortality of acute superior mesenteric artery (SMA) occlusion and evaluation of prognostic factors in recent years are lacking. METHODS: Patients with acute SMA occlusion were identified through the in-patient and autopsy registry between 1970 and 1982 (n = 270), 1987 to 1996 (n = 135), and 2000 and 2006 (n = 100) in Malmö, Sweden. RESULTS: The overal
Phenotypic characteristics were examined in melanoma-prone southern Swedish CDKN2A (p16-113insArg/p14ARF-128insSer) mutation families, in relation to the CDKN2A genotype, nevi, clinically atypical nevi (CAN) and melanoma. Individuals from eight melanoma-prone families, with index patients carrying the CDKN2A mutation, were offered skin examinations and genotyping (CDKN2A and MC1R). Ninety-three in
OBJECTIVE: To evaluate a new technical equipment for continuous recording of human fetal scalp temperature in labor.DESIGN: Experimental animal study.METHODS: Two temperature sensors were placed subcutaneously and intracranially on the forehead of 10 fetal lambs and connected to a temperature monitoring system. The system records temperatures simultaneously on-line and stores data to be analyzed o
