Transcriptome-wide analyses of early immune responses in lumpfish leukocytes upon stimulation with poly(I:C).

Background: Both bacterial and viral diseases are a major threat to farmed fish. As the antiviral immune mechanisms in lumpfish ( L.) are poorly understood, lumpfish leukocytes were stimulated with poly(I:C), a synthetic analog of double stranded RNA, which mimic viral infections, and RNA sequencing was performed.

The diagnostic accuracy of Sysmex XN for identification of pseudothrombocytopenia using various thresholds for definition of platelet aggregation.

Introduction: The aim of this study was to investigate the diagnostic accuracy of the flag PLT-Clumps from the WNR/WDF and the PLT-F channels from Sysmex XN and to study how different cut-offs for investigation for pseudothrombocytopenia (PTCP) and the definition of platelet aggregation affected the diagnostic accuracy.

Methods: A smear review was performed for samples with platelet count <150 × 10 /L and samples flagged for platelet aggregation by Sysmex XN-20. The samples were investigated for platelet aggregation in 30 fields using 40× objective.

Interleukin-1 Ligands and Receptors in Lumpfish ( L.): Molecular Characterization, Phylogeny, Gene Expression, and Transcriptome Analyses.

The interleukin (IL)-1 family play a fundamental role as immune system modulators. Our previous transcriptome-analyses of leukocytes from lumpfish ( L.) showed that IL-1β was among the most highly upregulated genes following bacterial exposure.

The proinflammatory cytokines TNF-α and IL-6 in lumpfish (Cyclopterus lumpus L.) -identification, molecular characterization, phylogeny and gene expression analyses.

The proinflammatory cytokines TNF-α and IL-6 are important mediators of inflammatory reactions and orchestrators of the immune system in vertebrate. In this study, we have identified TNF-α and IL-6 in lumpfish, molecular characterized them at mRNA and gene level, performed homology modelling and measured their gene expression in different tissues and upon in vitro stimulation. A comprehensive phylogenetic analysis of TNF-α teleost sequences give novel insight into the TNF -α biology.

Substantial Differences in Serum Concentrations of Psychoactive Drugs Measured in Samples Stored for 2 Days or More on Standard Serum Tubes Versus Serum Tubes Containing Gel Separators.

Background: Drugs may potentially adsorb to blood collection tubes containing gel separators in the preanalytical phase of therapeutic drug monitoring. The aim of this study was to compare measured concentrations of 28 psychoactive drugs and 13 metabolites in spiked serum samples stored on standard (plain) tubes versus barrier gel tubes during a 2-6-day period at room temperature.

Methods: Drug-free ("blank") serum samples spiked with mixes of antidepressants, antipsychotics, or mood stabilizers (valproic acid and lamotrigine), including relevant metabolites, were transferred to tubes with and without gel, that is, BD Vacutainer SST II Advance gel tubes and BD Vacutainer Glass Serum Tubes (Becton-Dickinson Company, Plymouth, United Kingdom).

Transcriptome-wide mapping of signaling pathways and early immune responses in lumpfish leukocytes upon in vitro bacterial exposure.

We performed RNA sequencing, identified components of the immune system and mapped early immune responses of lumpfish (Cyclopterus lumpus) leukocytes following in vitro exposure to the pathogenic bacterium Vibrio anguillarum O1. This is the first characterization of immune molecules in lumpfish at the gene level. In silico analyses revealed that genes encoding proteins involved in pathogen recognition, cell signaling and cytokines in mammals and teleosts are conserved in lumpfish.

Objective: Survival and causes of death (COD) in multiple sclerosis (MS) provide ultimate endpoints. We aimed to investigate survival and COD in a 60-year population-based MS cohort compared with the general population.

Methods: All patients with incident multiple sclerosis (MS) (N=1388) with onset during 1953-2012 in Hordaland County, Western Norway, were included.

In Silico Predictions and In Vivo Results of Drug-Drug Interactions by Ketoconazole and Verapamil on AZD1305, a Combined Ion Channel Blocker and a Sensitive CYP3A4 Substrate.

The objectives were to estimate and compare, in silico and in vivo, the effects of a strong and a moderate CYP3A4 inhibitor on AZD1305 pharmacokinetics. In silico, simulations were performed with the computer software Simcyp, and the predicted outcome was compared with the results observed in healthy male subjects. In silico, the geometric mean plasma exposure of AZD1305 + ketoconazole showed a 7.

Botulinum Toxin as Monotherapy in Symptomatic Trigeminal Neuralgia.

Background: Trigeminal neuralgia (TN) is one of the most agonizing facial pain disorders that humans endure. Studies on onabotulinum toxin A (BTX-A) treatment for TN are limited, but promising with respect to TN of no identifiable cause. We aimed to investigate the efficiency and safety of BTX-A treatment in a 60-year-old male with diabetes mellitus who in March 2013 presented with TN caused by an exostosis in Meckel's cave.

Objective: Investigate the incidence of multiple sclerosis during 1953-2013 and estimate the prevalence rate of MS on 1 January 2003 and 2013 in Hordaland County, Western Norway.

Methods: All patients with onset of disease in Hordaland 1953-2013 were identified in files from previous studies until 2003 and from patient records at the departments of Neurology, Haukeland University Hospital and Haugesund Hospital during 2003-2013. 1558 patients were assessed and 1402 of these were included, of whom 1035 were alive and living in Hordaland at prevalence day 1 January 2013.

Clinical assessment and management of sleep disorders in multiple sclerosis: a literature review.

The major sleep disorders are common in multiple sclerosis (MS) and are associated with significant morbidity. Despite this, the rate of recognition and management of these conditions are low. All types of sleep disorders are seen in patients with MS: insomnia, circadian rhythm sleep disorders, sleep-related movement disorders, sleep-related breathing disorders, hypersomnia (narcolepsy), and parasomnia (REM sleep behavior disorder; RBD).

Valproic Acid significantly lowers serum concentrations of olanzapine-an interaction effect comparable with smoking.

Background: Preliminary reports have indicated that valproic acid (VPA) reduces serum concentrations of olanzapine (OLZ). The aim of this study was to investigate the impact of VPA and other antiepileptic drugs (AEDs) on serum concentrations of OLZ and 3 of its major metabolites in a large-scale material of therapeutic drug monitoring samples.

Methods: OLZ-treated patients were stratified into subgroups according to coadministration of various AEDs, that is, lamotrigine (LTG; 110 patients/153 samples), VPA (92/166), LTG + VPA (7/12), carbamazepine (CBZ) (8/8), oxcarbazepine (2/3), gabapentin (3/4), levetiracetam (2/3), and topiramate (2/2).

Focal myositis--neurogenic phenomenon?

We report four cases of focal myositis. The patients, three men and one woman, had painful muscle hypertrophy, affecting four different sites. MRI confirmed the muscle enlargement and oedema.

Relative prevalence of upper respiratory tract obstructive disorders in two breeds of harness racehorses (185 cases: 1998-2006).

Reasons For Performing Study: Two genetically and phenotypically distinct horse breeds are used for harness racing in Scandinavia: the Standardbred (SB) and Coldblooded Trotter. These racehorses have identical environmental, management and racing conditions. Therefore, this study was undertaken to identify and compare the relative prevalence of upper respiratory tract (URT) obstructive disorders in these 2 breeds.

Impact of the CYP2D6 genotype on steady-state serum concentrations of aripiprazole and dehydroaripiprazole.

Objective: Aripiprazole is an atypical antipsychotic drug which is metabolized by the polymorphic enzyme cytochrome P450 2D6 (CYP2D6). The aim of the present study was to investigate the impact of the CYP2D6 genotype on serum concentrations of aripiprazole (ARI) and to determine the sum of ARI and the active metabolite dehydroaripiprazole (DARI) in psychiatric patients.

Methods: Data on steady-state serum concentrations and the CYP2D6 genotypes of patients treated with ARI were extracted from a routine therapeutic drug monitoring database.

Interactive effects of sex and 5-HTTLPR on mood and impulsivity during tryptophan depletion in healthy people.

Background: Serotonin (5-HT) plays a central role in mood regulation and impulsivity. We studied whether healthy men and women react differently on mood and impulsivity measures during acute tryptophan depletion (ATD). We also studied the relative contribution of a functional length triallelic polymorphism in the promoter region of the serotonin transporter, designated 5-HTTLPR, to the behavioral responses to ATD.

Pharmacokinetic variability of aripiprazole and the active metabolite dehydroaripiprazole in psychiatric patients.

Aripiprazole is a new atypical antipsychotic drug with a partial agonist activity at dopamine 2 and serotonin 1A receptors. The metabolism of aripiprazole involves both cytochrome P450 2D6 (CYP2D6) and CYP3A4. This study investigated the pharmacokinetic variability of aripiprazole and the active metabolite dehydroaripiprazole on the basis of 155 drug monitoring samples from psychiatric patients treated with therapeutic doses of aripiprazole (10-30 mg/day).

In vivo effects of beta-glucan and LPS on regulation of lysozyme activity and mRNA expression in Atlantic salmon (Salmo salar L.).

The present study was undertaken to compare the effects of intraperitoneally injected bacterial lipopolysaccharide (LPS) and yeast beta-glucan on lysozyme activity in Atlantic salmon, and to explore what organ(s) are responsible for the increase in plasma lysozyme activity induced by the compounds. The results indicated that LPS stimulates plasma lysozyme activity at least as efficiently as beta-glucan. The lysozyme gene was shown to be transcribed in head kidney, spleen, liver and intestine, and accumulation of transcript was demonstrated in response to both beta-glucan and LPS in all of these organs.

Lowering of serotonin by rapid tryptophan depletion increases impulsiveness in normal individuals.

Rationale: Reduced serotonergic activity has been associated with impulsive behavior; however, intervention studies have been scarce.

Objectives: To examine whether induced lowering of serotonin (5-HT) levels would increase behavioral measures of impulsivity.

Methods: Twenty-four healthy young males ingested a mixture of the essential amino acids except for tryptophan in a balanced, randomized, double-blind, placebo-controlled, cross-over study design.

Serum amyloid A transcription in Atlantic salmon (Salmo salar L.) hepatocytes is enhanced by stimulation with macrophage factors, recombinant human IL-1 beta, IL-6 and TNF alpha or bacterial lipopolysaccharide.

Serum amyloid A (A-SAA) has previously been reported to be an acute-phase protein in salmonids. Hepatocytes represent a major source of A-SAA in salmonids, but nothing is known about hepatocyte SAA synthesis in fish. In the present work, the expression of A-SAA transcripts in primary cultures of Atlantic salmon hepatocytes in response to macrophage derived cytokines, human recombinant cytokines and bacterial lipopolysaccharide (LPS) was studied by Northern blot analysis.

Onset of bronchodilation and finger tremor induced by salmeterol and salbutamol in asthmatic patients.

Salmeterol is a beta-agonist with bronchodilator properties that last for at least 12 h after inhalation. However, the onset of action of salmeterol immediately after inhalation has not been sufficiently investigated. In the present study, the onset of action and tremor-inducing effect of two doses of inhaled salmeterol (50 and 100 microg) were compared with inhaled salbutamol (200 and 400 microg) and placebo.

Efficacy of cumulative doses of salbutamol administered via Turbuhaler or Diskhaler in patients with reversible airway obstruction.

The study aimed to estimate the relative dose potency of salbutamol inhaled via Turbuhaler and Diskhaler. The 24 adult patients participating had chronic reversible airway obstruction. The study was of a double-blind, double-dummy, crossover, randomized design.
