Elemental composition in vesicles of an arbuscular mycorrhizal fungus, as revealed by PIXE analysis.

We investigated element accumulation in vesicles of the arbuscular mycorrhizal (AM) fungus Glomus intraradices, extracted from the roots of inoculated leek plants. The elemental composition (elements heavier than Mg) was quantified using particle-induced X-ray emission (PIXE), in combination with scanning transmission ion microscopy (STIM). In vesicles, P was the most abundant of the elements anal

Prenatal compared with postnatal cleft diagnosis: What do the parents think?

Since the 1980s, prenatal detection of cleft lip with or without cleft palate (CLP) is possible with a transabdominal ultrasound. The improvement of prenatal detection has resulted in an increased demand for prenatal information and counselling. The aim of this study was to, by means of a questionnaire, evaluate how families, who received the diagnosis prenatally and postnatally, respectively, thi

Can resting-state functional MRI serve as a complement to task-based mapping of sensorimotor function? A test-retest reliability study in healthy volunteers.

PURPOSE: To investigate if resting-state functional MRI (fMRI) reliably can serve as a complement to task-based fMRI for presurgical mapping of the sensorimotor cortex. MATERIALS AND METHODS: Functional data were obtained in 10 healthy volunteers using a 3 Tesla MRI system. Each subject performed five bilateral finger tapping experiments interleaved with five resting-state experiments. Following p

Disturbed alpha-cell function in mice with beta-cell specific overexpression of human islet amyloid polypeptide.

Exogenous administration of islet amyloid polypeptide (IAPP) has been shown to inhibit both insulin and glucagon secretion. This study examined alpha-cell function in mice with beta-cell specific overexpression of human IAPP (hIAPP) after an oral protein gavage (75 mg whey protein/mouse). Baseline glucagon levels were higher in transgenic mice (41 +/- 4.0 pg/mL, n = 6) than in wildtype animals (19

Caring for undernourished patients in an orthopaedic setting.

This study elucidates the nursing of undernourished patients as experienced by eight registered clinical nurses and five nursing assistants by using content analysis. The participants' narratives describe the inner perspective of caring for undernourished patients, known in Sweden as ;the thin ones'. Categories identified were: frustration in nursing, joy in nursing and that undernourishment is ta

Cardiomyocyte cell cycle control and growth estimation in vivo- an analysis based on cardiomyocyte nuclei.

AIMS: Adult mammalian cardiomyocytes are traditionally viewed as being permanently withdrawn from the cell cycle. While some groups have reported none, others have reported extensive mitosis in adult myocardium under steady state conditions. Recently, a highly specific assay of (14)C dating in humans has suggested a continuous generation of cardiomyocytes in the adult, albeit at a very low rate. M

Hydrophobic ion pairing of a minocycline/Ca(2+)/AOT complex for preparation of drug-loaded PLGA nanoparticles with improved sustained release.

Polymeric nanoparticles is an established and efficient means to achieve controlled release of drugs. Incorporation of minocycline, an antibiotic with anti-inflammatory and neuroprotective properties, into biodegradable nanoparticles may therefore provide an efficient means to combat foreign body reactions to implanted electrodes in the brain. However, minocycline is commonly associated with poor

Gastrointestinal dysfunction contributes to weight loss in Huntington's disease mice.

Weight loss is the most important non-neurological complication of Huntington's disease (HD). It correlates with disease progression and affects the quality of life of HD patients, suggesting that it could be a valuable target for therapeutic intervention. The mechanism underlying weight loss in HD is unknown. Mutant huntingtin, the protein that causes the disease, is not only expressed in the bra

Transanal Endorectal vs. Duhamel Pull-Through for Hirschsprung's Disease.

INTRODUCTION: The aim of this study was to test the hypothesis that the early functional outcome for patients with rectosigmoid Hirschsprung's disease (HD) is comparable for the Duhamel pull-through procedure and the transanal endorectal pull-through (TERPT) procedure, with less discomfort for the patient postoperatively after the TERPT technique. MATERIAL AND METHODS: Eleven patients operated on

Cost-effectiveness of etanercept treatment in early active rheumatoid arthritis followed by dose adjustment.

Objectives: To explore the cost-effectiveness of early biologic treatment, followed by dose-reduction in the case of remission, of active rheumatoid arthritis (RA), compared with standard treatment with methotrexate (MTX) in Sweden.Methods: Effectiveness (function, disease activity, erosions) in early RA for both alternatives was taken from a clinical trial comparing etanercept (ETA) combined with

Nucleotide-binding and oligomerization domain-like receptors and retinoic acid inducible gene-like receptors in human tonsillar T lymphocytes.

Nucleotide-binding and oligomerization domain (NOD) -like receptors (NLRs) and retinoic acid-inducible gene (RIG) -like receptors (RLRs) are recently discovered cytosolic pattern-recognition receptors sensing mainly bacterial components and viral RNA, respectively. Their importance in various cells and disorders is becoming better understood, but their role in human tonsil-derived T lymphocytes re

Body mass index and breast cancer survival in relation to the introduction of mammographic screening.

AIMS: Mammographic screening reduces mortality in breast cancer. It is not known if this reduction is more pronounced in certain groups. Obesity has been associated with worse survival following breast cancer diagnosis. This study investigates BMI in relation to breast cancer mortality, and if this association is affected by invitation to mammographic screening. METHODS: In 1976, a randomised mamm

Childhood attention-deficit hyperactivity disorder as an extreme of a continuous trait: a quantitative genetic study of 8,500 twin pairs.

Background: Although the clinical utility of categorically defined attention-deficit hyperactivity disorder (ADHD) is well established, there is also strong evidence supporting the notion of ADHD as an extreme of a continuous trait. Nevertheless, the question of whether the etiology is the same for different levels of DSM-IV ADHD symptoms remains to be investigated. The aim of this study was to as

Autism spectrum disorders in institutionalized subjects.

What do we know about the prevalence and the specific features of autism spectrum disorders (ASDs) among subjects in forensic psychiatry and special youth centres? A clinical case series consisting of 42 subjects with ASD, recruited from three well-characterized populations in forensic psychiatry and special youth care, was used to determine: 1) the prevalence of ASD in these institutions (at leas

Vectorcardiogram synthesized from the 12-lead electrocardiogram to image ischemia.

BACKGROUND: Knowledge of the location and size of ischemic myocardium at risk for infarction could impact prehospital patient triage and reperfusion therapy. The 12-lead electrocardiogram (ECG) can roughly estimate ischemia size; however, individual precordial ECG leads are at different distances from the left ventricle (LV) and certain LV walls have greater effects on the ECG. Vectorcardiographic
