Insular cortex activation in a patient with "sensed presence"/ecstatic seizures.

Objective: Seizures with an aura of a "sensed presence," a religious emotion, or feelings of euphoria (ecstatic seizures) are characterized by heightened self-awareness. A previous case report on a patient with epilepsy and "sensed presence" as an aura described hypoperfusion in both temporal lobes and a local ictal increase in the left frontoparietal area. A reexamination of the data was suggested by a recent study of patients with ecstatic seizures, which proposed that hyperactivation of the left anterior insula might be a potential cause.

Growth hormone treatment in short children born prematurely--data from KIGS.

Context: Children born prematurely with growth failure might benefit from GH treatment.

Objectives: The aim was to evaluate the first year growth response to GH treatment in short children born prematurely and to identify predictors of the growth response.

Design/patients: A total of 3215 prepubertal children born prematurely who were on GH treatment were selected from KIGS (The Pfizer International Growth Database), a large observational database.

Interpersonal psychotherapy for Finnish community patients with moderate to severe major depression and comorbidities: a pilot feasibility study.

Objective: Interpersonal psychotherapy (IPT) has shown efficacy in randomized controlled trials. No reports exist on IPT for depressed patients with severe psychiatric comorbidities in public outpatient clinics. This pilot feasibility study assessed preliminary effectiveness and patient satisfaction with IPT for depressed patients with psychiatric comorbidities in municipal outpatient care in Turku, Finland.

Convergent patterns of long-distance nocturnal migration in noctuid moths and passerine birds.

Vast numbers of insects and passerines achieve long-distance migrations between summer and winter locations by undertaking high-altitude nocturnal flights. Insects such as noctuid moths fly relatively slowly in relation to the surrounding air, with airspeeds approximately one-third of that of passerines. Thus, it has been widely assumed that windborne insect migrants will have comparatively little control over their migration speed and direction compared with migrant birds.

N-acetyl-L-cysteine increases acute graft-versus-host disease and promotes T-cell-mediated immunity in vitro.

N-acetyl-L-cysteine (NAC) is a thiol antioxidant that stimulates glutathione synthesis in cells. Several studies indicate that NAC possesses immunomodulatory properties in vitro, but both inhibitory and activating effects on immunity have been reported. We observed that allogeneic stem cell transplantation (ASCT) patients who were randomized to receive NAC 100  mg/kg/day (n=73) had an increased prevalence of grade II-V acute graft-versus-host disease (GvHD) compared to patients who did not receive NAC (n=87), indicating that NAC has an immunostimulatory effect in vivo.

Altered O-glycosylation profile of MUC2 mucin occurs in active ulcerative colitis and is associated with increased inflammation.

Background: The MUC2 mucin organizes the two mucus layers in the colon. This mucin carries a large number of O-glycans that are assumed to be attachment sites for the commensal flora found in the outer mucus layer.

Methods: Single biopsies from the sigmoid colon of controls (25) and patients with inactive (13) or active (15) ulcerative colitis (UC) were collected during routine colonoscopy.

Perceived burden of illness in patients entering for treatment in a university hospital--is the threshold to secondary care higher for patients with depression than for those with somatic disorders?

Background: The threshold to secondary health care should be similar for all patients independent of the underlying disease. This study compared, using a validated health-related quality of life (HRQoL)-instrument, whether the perceived burden of illness is similar in patients admitted for secondary care treatment into a university hospital because of one of six common conditions.

Methods: HRQoL, assessed by the generic 15D instrument before elective treatment, was compared in six groups: operative treatment of cataract (n=219), operative treatment of cervical or lumbar radicular pain (n=270), hysterectomy due to benign uterine conditions (n=337), hip or knee replacement surgery (n=223), coronary angiography due to suspected coronary artery disease (n=261), and secondary care treatment of depression (n=89).

Road dust emissions from paved roads measured using different mobile systems.

Very few real-world measurements of road dust suspension have been performed to date. This study compares two different techniques (referred to as Sniffer and Emma) to measure road dust emissions. The main differences between the systems are the construction of the inlet, different instruments for recording particulate matter (PM) levels, and different loads on the wheel axes (the weight of Sniffer was much higher than that of Emma).

A systematic evaluation of expression of HERV-W elements; influence of genomic context, viral structure and orientation.

Background: One member of the W family of human endogenous retroviruses (HERV) appears to have been functionally adopted by the human host. Nevertheless, a highly diversified and regulated transcription from a range of HERV-W elements has been observed in human tissues and cells. Aberrant expression of members of this family has also been associated with human disease such as multiple sclerosis (MS) and schizophrenia.

LDL-associated apolipoprotein J and lysozyme are associated with atherogenic properties of LDL found in type 2 diabetes and the metabolic syndrome.

Objectives: Exchangeable low-density lipoprotein (LDL)-associated proteins can affect the atherogenic properties of LDL. Our aim was to analyse the protein composition of LDL from individuals with or without type 2 diabetes and the metabolic syndrome (T2DM) in relation to other LDL particle characteristics, to assess whether certain proteins associate more with certain subclasses of LDL typical for T2DM, such as small, apoCIII-rich LDL.

Design: Low-density lipoprotein from two cohorts of 61-year-old men (n = 19 and 64) with or without T2DM was isolated using size-exclusion chromatography or deuterium oxide-based ultracentrifugation.

Epidemiological fallacies of modern psychiatric research.

Background: Psychiatric epidemiology is an important cornerstone of research in psychiatry and integral for the treatment and care of people suffering from psychiatric disorders. However, psychiatric epidemiology is a difficult science, which is often beset with methodological problems.

Aims: In light of this, the current review sought to explore 13 of the common methodological issues in psychiatric epidemiology.

Effect of sonication and serum proteins on copper release from copper nanoparticles and the toxicity towards lung epithelial cells.

Abstract Different methodological settings can influence particle characteristics and toxicity in nanotoxicology. The aim of this study was to investigate how serum proteins and sonication of Cu nanoparticle suspensions influence the properties of the nanoparticles and toxicological responses on human lung epithelial cells. This was investigated by using methods for particle characterization (photon correlation spectroscopy and TEM) and Cu release (atomic absorption spectroscopy) in combination with assays for analyzing cell toxicity (MTT-, trypan blue- and Comet assay).

Wear particles from studded tires and granite pavement induce pro-inflammatory alterations in human monocyte-derived macrophages: a proteomic study.

Airborne particulate matter is considered to be one of the environmental contributors to the mortality in cancer, respiratory, and cardiovascular diseases. For future preventive actions, it is of major concern to investigate the toxicity of defined groups of airborne particles and to clarify their pathways in biological tissues. To expand the knowledge beyond general inflammatory markers, this study examined the toxicoproteomic effects on human monocyte derived macrophages after exposure to wear particles generated from the interface of studded tires and a granite-containing pavement.

Optimism and pessimism as predictors of work disability with a diagnosis of depression: a prospective cohort study of onset and recovery.

Background: Personality characteristics are assumed to affect to the vulnerability to depression and its outcomes. The aim of this study was to examine optimism and pessimism as predictors of depression-related work disability and subsequent return to work.

Methods: We conducted a prospective cohort study of 38,214 public sector employees with no record of diagnosed depression.

Resonant inelastic scattering spectra of free molecules with vibrational resolution.

Inelastic x-ray scattering spectra excited at the 1s(-1)π* resonance of gas phase O2 have been recorded with an overall energy resolution that allows for well-resolved vibrational progressions. The nuclear wave packet dynamics in the intermediate state is reflected in vibrational excitations of the electronic ground state, and by fine-tuning the excitation energy the dissociation dynamics in the predissociative B'(3)Πg final state is controlled.

Perceptual and acoustic reliability estimates for the Speech Disorders Classification System (SDCS).

A companion paper describes three extensions to a classification system for paediatric speech sound disorders termed the Speech Disorders Classification System (SDCS). The SDCS uses perceptual and acoustic data reduction methods to obtain information on a speaker's speech, prosody, and voice. The present paper provides reliability estimates for the two perceptual methods (narrow phonetic transcription; prosody-voice coding) and the acoustic analysis methods the SDCS uses to describe and classify a speaker's speech competence, precision, and stability.

Extensions to the Speech Disorders Classification System (SDCS).

This report describes three extensions to a classification system for paediatric speech sound disorders termed the Speech Disorders Classification System (SDCS). Part I describes a classification extension to the SDCS to differentiate motor speech disorders from speech delay and to differentiate among three sub-types of motor speech disorders. Part II describes the Madison Speech Assessment Protocol (MSAP), an ∼ 2-hour battery of 25 measures that includes 15 speech tests and tasks.

Effects of antidepressant drug treatment and psychotherapy on striatal and thalamic dopamine D2/3 receptors in major depressive disorder studied with [11C]raclopride PET.

Antidepressant drug treatment and psychotherapy are both effective in treating major depression, but there are no published studies comparing the effects of these two treatments on the dopaminergic neurotransmitter system in major depression. We conducted a randomized comparative study on the effects of fluoxetine medication and short-term psychodynamic psychotherapy on striatal and thalamic dopamine D(2/3) receptors in patients with major depression. Duration of the treatment was 4 months, and dopamine D(2/3) receptor binding was quantified before and after treatment as the binding potential (BP (ND)) using [(11)C]raclopride and 3D positron emission tomography.

Bioaccessibility, bioavailability and toxicity of commercially relevant iron- and chromium-based particles: in vitro studies with an inhalation perspective.

Background: Production of ferrochromium alloys (FeCr), master alloys for stainless steel manufacture, involves casting and crushing processes where particles inevitably become airborne and potentially inhaled. The aim of this study was to assess potential health hazards induced by inhalation of different well-characterized iron- and chromium-based particles, i.e.

Granulocyte colony-stimulating factor induced acute and chronic graft-versus-host disease.

Background: A recent experimental study in mice shed new light on the controversy as to whether granulocyte colony-stimulating factor (G-CSF) increases graft-versus-host disease (GVHD). Total body irradiation and bone marrow were found to be prerequisites for acute GVHD. This study encouraged us to perform a retrospective clinical study.

A perfectly matched layer applied to a reactive scattering problem.

The perfectly matched layer (PML) technique is applied to a reactive scattering problem for accurate domain truncation. A two-dimensional model for dissociative adsorbtion and associative desorption of H(2) from a flat surface is considered, using a finite difference spatial discretization and the Arnoldi method for time-propagation. We compare the performance of the PML to that of a monomial complex absorbing potential, a transmission-free complex absorbing potential, and to exterior complex scaling.

The comet assay in nanotoxicology research.

Nanoscale particles can have impressive and useful characteristics, but the same properties may be problematic for human health. From this perspective it is critical to assess the ability of nanoparticles to cause DNA damage. This review focuses on the use of the comet assay in nanotoxicology research.
