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

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

WNT-5A triggers Cdc42 activation leading to an ERK1/2 dependent decrease in MMP9 activity and invasive migration of breast cancer cells

An important role for WNT-5A is implicated in a variety of tumors, including breast carcinoma. We previously showed that WNT-5A signaling inhibits migration and metastasis of breast cancer cells, and that patients with primary breast cancer in which WNT-5A was expressed have a better prognosis. Despite the fact that RhoGTPase Cdc42 is commonly associated with increased cell migration, we here show

Drug costs and benefits of medical treatments in high-unmet need solid tumours in the Nordic countries

Introduction: Regional and hospital decision-makers increasingly require analyses assessing the cost-benefit profile of new cancer drugs. This analysis evaluates the cost-benefit profile of nano albumin-bound paclitaxel (nab-paclitaxel) in pancreatic cancer, versus other drugs indicated in high-unmet need solid tumour indications in Nordic countries (Sweden, Denmark, Finland, Norway and Sweden). M

Mechanical symptoms and arthroscopic partial meniscectomy in patients with degenerative meniscus tear : A secondary analysis of a randomized trial

Background: Recent evidence shows that arthroscopic partial meniscectomy (APM) offers no benefit over conservative treatment of patients with a degenerative meniscus tear. However, patients who report mechanical symptoms (sensations of knee catching or locking) may benefit from APM. Objective: To assess whether APM improves mechanical symptoms better than sham surgery. Design: Randomized, patient-

Expression of the chemokine CXCL14 in the tumour stroma is an independent marker of survival in breast cancer

Background:Expression of the chemokine CXCL14 has previously been shown to be elevated in the tumour stroma of, for example, prostate and breast cancer. Cancer-associated fibroblast-derived CXCL14 enhances tumour growth in mouse models of prostate and breast cancer. However, the prognostic significance of compartment-specific expression of CXCL14 has not been studied.Methods:CXCL14 mRNA expression

The temporal relationship between poor lung function and the risk of diabetes

Background: The association between impaired lung function and diabetes risk has been established in the past, however the temporal and causal relationships between the two remain unclear. We assessed the relationship between baseline FEV1 and FVC and risk of incident diabetes at different time intervals for participants in the Malmö Preventive Project cohort. Methods: Baseline lung function was a
