Functional and immunochemical characterisation of different antibodies against the erythropoietin receptor
Since it was discovered that the hematopoietic hormone erythropoetin (EPO) exerts neuroprotective effects in the CNS, many studies on the EPO receptor (EPOR) function and localisation in the CNS have been performed. For this purpose, commercially available anti-EPOR antibodies have often been applied. As the literature data on these antibodies show inconsistencies, we here systematically compared
Comparison of neuroprotective effects of erythropoietin (EPO) and carbamylerythropoietin (CEPO) against ischemia-like oxygen-glucose deprivation (OGD) and NMDA excitotoxicity in mouse hippocampal slice cultures
In addition to its well-known hematopoietic effects, erythropoietin (EPO) also has neuroprotective properties. However, hematopoietic side effects are unwanted for neuroprotection, underlining the need for EPO-like compounds with selective neuroprotective actions. One such compound, devoid of hematopoietic bioactivity, is the chemically modified, EPO-derivative carbamylerythropoietin (CEPO). For c
High-dose erythropoietin alters platelet reactivity and bleeding time in rodents in contrast to the neuroprotective variant carbamyl-erythropoietin (CEPO)
The haematopoietic hormone erythropoietin (EPO) has neuroprotective properties and is currently being explored for treatment of stroke and other neurological disorders. Short-term, high-dose treatment with EPO seems to improve neurological function of stroke patients but may be associated with increased thrombotic risk, whereas alternative non-erythropoietic neuroprotective derivatives of EPO, suc
Differences in body structure and function between patients with systemic lupus erythematosus and healthy individuals, with particular reference to joint hypermobility
Objectives: To explore differences in body structure and function in systemic lupus erythematosus (SLE) patients and controls, with particular reference to joint hypermobility, and to evaluate the usefulness of the Brighton criteria for diagnosing joint hypermobility syndrome (JHS) in SLE. Method: Female SLE patients were, according to age group, consecutively invited to participate in the study.
TNF-induced superoxide anion production in adherent human neutrophils involves both the p55 and p75 TNF receptor
TNF, a potent activator of neutrophil granulocytes, acts via two cell-surface receptors: the p55-TNF receptor (TNF-R55) and the p75-TNF receptor (TNF-R75), which can be cleaved from the cell surface and thus form soluble TNF-binding proteins (TNF-BP). The role of the two receptors in activation of the neutrophil respiratory burst was investigated. Two mAbs reacting with TNF-R55 (H398 and TBP2) ind
Transactivation of EGF receptors in chicken Müller cells by α2A-adrenergic receptors stimulated by brimonidine
PURPOSE: Alpha2-adrenergic receptor agonists are used in glaucoma treatment and have been shown to have some neuroprotective effects. We performed this study to test the hypothesis that epidermal growth factor receptors on chicken Müller cells are transactivated by α2-adrenergic receptors and we focused on the extracellular signal-activated kinases 1/2 (ERK) pathway.METHODS: Embryonic chicken reti
Injury-associated PACAP expression in rat sensory and motor neurons is induced by endogenous BDNF
Peripheral nerve injury results in dramatic upregulation in pituitary adenylate cyclase activating polypeptide (PACAP) expression in adult rat dorsal root ganglia and spinal motor neurons mirroring that described for the neurotrophin brain derived neurotrophic factor (BDNF). Thus, we posited that injury-associated alterations in BDNF expression regulate the changes in PACAP expression observed in
Multiple receptor tyrosine kinases are expressed in adult rat retinal ganglion cells as revealed by single-cell degenerate primer polymerase chain reaction
BACKGROUND: To achieve a better understanding of the repertoire of receptor tyrosine kinases (RTKs) in adult retinal ganglion cells (RGCs) we performed polymerase chain reaction (PCR), using degenerate primers directed towards conserved sequences in the tyrosine kinase domain, on cDNA from isolated single RGCs univocally identified by retrograde tracing from the superior colliculi.RESULTS: All the
Differential molecular and behavioural response to L-DOPA in mice injected with 6-hydroxydopamine in the striatum or in the medial forebrain bundle
Unilateral lesions of nigrostriatal dopamine ( DA) pathways with 6-hydroxydopamine (6-OHDA) can be used to obtain a model of Parkinson's disease in the mouse. In the present study we examine two types of unilateral 6-OHDA lesions in the mouse for their ability to induce stable motor deficits and supersensitive molecular and behavioural response to L-DOPA.
Altered behavioural responses and functional recovery in rats following sciatic nerve compression and early vs late decompression
Objective: The aim of the study was to examine sensory behaviour and functional recovery in rats during nerve compression and after decompression. Compression injury is a far more common condition than nerve transection. The condition is characterised by numbness and a tingling/burning sensation, and some patients experience pain and allodynia during compression or after decompression treatment. T
Social anxiety and related social impairment are linked to self-efficacy and dysfunctional coping strategies.
Large Eddy Simulation and Experiments of Stratified Lean Premixed Methane/Air Turbulent Flames
This paper presents a joint large eddy simulation and laser diagnostic investigation of premixed turbulent low swirl flames. A lean premixed methane/air mixture, of the equivalence ratio 0.60-0.66, is injected from a 50 mm diameter low swirl burner to a low speed co-flowing air at room temperature and pressure. The level-set G-equation is employed to simulate the inner layer flame front. Flamelet
Amorphous silica transport in the Ganges basin: Implications for Si delivery to the oceans
Rivers transport similar to 6 x 10(12) mol yr(-1) of dissolved Si (DSi) from the continents to the oceans. They also carry amorphous silica (ASi), solid phases likely to dissolve in seawater. Unfortunately, the magnitude of this flux is poorly constrained at a global scale. We present 92 new ASi values from suspended particulate matter (SPM) from the Ganges basin. Bulk SPM is 1.2% ASi, and mean AS
Value of treatment in clinical trials versus the real world : the case of abiraterone acetate (Zytiga) for postchemotherapy metastatic castration-resistant prostate cancer patients in Sweden
Objective: In a randomized clinical trial (COU-AA-301), abiraterone acetate (Zytiga®) was shown to be superior to prednisone in the treatment of metastatic castration-resistant prostate cancer (mCRPC). However, the value of abiraterone treatment for patients with mCRPC in clinical practice in Sweden is not known. The aim of this study was to compare the outcomes and treatment patterns of abiratero
Public safety investigations-A new evolutionary step in safety enhancement?
A historical overview highlights the evolutionary nature of developments in accident investigations in the transport industry. Based on a series of major events outside transportation, the concept of accident investigations has broadened to other domains and to a widening of the scope of the investigation. Consequently, existing investigation boards are forced to adapt their mandates, missions and
Non-coding RNAs in Prostate Cancer: From Discovery to Clinical Applications.
Prostate cancer is a heterogeneous disease for which the molecular mechanisms are still not fully elucidated. Prostate cancer research has traditionally focused on genomic and epigenetic alterations affecting the proteome, but over the last decade non-coding RNAs, especially microRNAs, have been recognized to play a key role in prostate cancer progression. A considerable number of individual micro
Magnetostatic interactions in planar ring-like nanoparticle structures
Numerical calculations of equilibrium state energies and local magnetic fields in planar ring-like nanoparticle structures were performed. The dipole–dipole, Zeeman and magnetic anisotropy interactions were included into the model. The result of their competition depends on the value of the external magnetic field, magnetic parameters of an individual nanoparticle, size and shape of the structures
MYBPC3 hypertrophic cardiomyopathy can be detected by using advanced ECG in children and young adults
Introduction The conventional ECG is commonly used to screen for hypertrophic cardiomyopathy (HCM), but up to 25% of adults and possibly larger percentages of children with HCM have no distinctive abnormalities on the conventional ECG, whereas 5 to 15% of healthy young athletes do. Recently, a 5-min resting advanced 12-lead ECG test ("A-ECG score") showed superiority to pooled criteria from the st
BRCA2 Polymorphic Stop Codon K3326X and the Risk of Breast, Prostate, and Ovarian Cancers
Background: The K3326X variant in BRCA2 (BRCA2∗c.9976A>T p.Lys3326∗rs11571833) has been found to be associated with small increased risks of breast cancer. However, it is not clear to what extent linkage disequilibrium with fully pathogenic mutations might account for this association. There is scant information about the effect of K3326X in other hormonerelated cancers. Methods: Using weighted lo
