Baseline and longitudinal grey matter changes in newly diagnosed Parkinson's disease : ICICLE-PD study

Mild cognitive impairment in Parkinson's disease is associated with progression to dementia (Parkinson's disease dementia) in a majority of patients. Determining structural imaging biomarkers associated with prodromal Parkinson's disease dementia may allow for the earlier identification of those at risk, and allow for targeted disease modifying therapies. One hundred and five non-demented subjects

Beyond prostate-specific antigen : Utilizing novel strategies to screen men for prostate cancer

Purpose of review The purpose of this article is to review blood and urine tests that are currently available and under investigation for a role in prostate cancer screening and detection. Recent findings Compared with total prostate-specific antigen (PSA) alone, its combination with percentage free-to-total PSA contributes greater specificity for prostate cancer, and is a component of two newer b

Involvement of the serotonin system in L-dopa-induced dyskinesias

The ability of L-dopa to relieve the motor impairments in Parkinson's disease patients declines over time, and side-effects, such as dyskinesias, appear--limiting the use of the drug in the advanced stage of the disease. Serotonergic neurons are able to convert L-dopa to dopamine and to store this neurotransmitter in synaptic vesicles. This peculiarity might be very important in the advanced disea

Striatal c-fos Induction by Cocaine or Apomorphine Occurs Preferentially in Output Neurons Projecting to the Substantia Nigra in the Rat

Fluorogold or rhodamine-labelled latex beads were injected in the substantia nigra (SN) or the globus pallidus (GP) in order retrogradely to label striatal output neurons that project to the two target structures. Ten days later, striatal c-fos was induced by systemic administration of cocaine (five normal rats; 25 mg/kg cocaine i.p. 2 h before killing) or apomorphine (five unilaterally dopamine-d

Rapid identification of intact bacterial resistance plasmids via optical mapping of single DNA molecules

The rapid spread of antibiotic resistance-currently one of the greatest threats to human health according to WHO-is to a large extent enabled by plasmid-mediated horizontal transfer of resistance genes. Rapid identification and characterization of plasmids is thus important both for individual clinical outcomes and for epidemiological monitoring of antibiotic resistance. Toward this aim, we have d

Common starting points, different directions. Assimilation policies for 'Travelling families' in Norway, Sweden and Finland c. 1850-1900.

In the late 19th century, political debates emerged in Sweden and Norway as well as in Finland concerning Travelling families – in this article defined as indigenous itinerant families whom the settled population pejoratively designated with terms such as ‘tatere’ (Norway), ‘tattare’ (Sweden) or ‘zigenare’ (Finland). In this article, these debates are compared, and the transfer of ideas and propos

Catheter closure of atrial septal defect in the elderly (≥ 65 years). A worthwhile procedure

Background Secundum atrial septal defect (ASD2) is one of the most common cardiac malformations diagnosed in adult life. Catheter closure has made treatment possible even in patients of high age. However, published outcome data for elderly patients is limited. The aim of this study was to report, on a national basis, the long-term outcome of ASD2 catheter closure in the elderly. Material and resul

Study of β-delayed charged particle emission of 11Li : Evidence of new decay channels

The break-up of the 18.2 MeV state in 11Be was studied in a 11Li β-decay experiment. We report here on the study of the dominating breakup channels involving na6He or 3n2α in the final state, with special emphasis dedicated in this contribution to the three-particle channel. The two emitted charged particles were detected in coincidence using a highly segmented experimental set-up. The observed ex

Nuclear structure studies of neutron-rich Cu and Zn isotopes produced by means of proton-induced fission of 238U

The neutron-rich nuclei 72Ni and 72Cu have been produced in the proton-induced fission of 238U at the LISOL and ISOLDE facilities of Louvain-La-Neuve and CERN. Partial β-decay schemes are presented, giving some information about the nuclear structure of their daughter nuclei 72Cu and 72Zn. The lifetime of 72Cu was determined to be T1/2 = 6.63(3) s, in line with previous measurements. No β-decaying

Asymmetry in the super-allowed β-transitions of the A=9 isobars

We report here on the recent β-decay studies of the A = 9 isobar made at ISOLDE/CERN. Mirror beta transitions in the A=9 chain are compared and a large asymmetry factor is deduced for the transitions to high excitation energy in 9Be (11.8 MeV) arid 9B (12.2 MeV) fed in the β-decay of 9Li and 9C respectively. It is shown that the asymmetry is not due to experimental problems or differences in the m

Event-Based State Estimation Using an Improved Stochastic Send-on-Delta Sampling Scheme

Event-based sensing and communication holds the promise of lower resource utilization and/or better performance for remote state estimation applications found in e.g. networked control systems. Recently, stochastic event-triggering rules have been proposed as a means to avoid the complexity of the problem that normally arises in event-based estimator design. By using a scaled Gaussian function in

Case management for older persons with multi-morbidity. Experiences of an intervention from the perspectives of older persons, family members, case managers and health and social care staff members

Complex health systems make it difficult to ensure a continuity of care for older persons with multi-morbidity, and risk fragmented care. Fragmented care could affect the quality and safety of the care provided. Case management could provide an approach to counteract this unfavourable situation. Case management is practised by case managers and aims to improve the coordination of healthcare and soComplex health systems make it difficult to ensure a continuity of care for older persons with multi-morbidity, and risk fragmented care.

Hypothalamic volume loss is associated with reduced melatonin output in Parkinson's disease

BACKGROUND: Recent studies have suggested that melatonin-a hormone produced by the pineal gland under circadian control-contributes to PD-related sleep dysfunction. We hypothesized that degenerative changes to the neural structures controlling pineal function (especially the suprachiasmatic nuclei of the anterior hypothalamus) may be responsible for reduced melatonin output in these patients. We c

Advancing pharmacotherapy for treating Huntington's disease : a review of the existing literature

INTRODUCTION: Huntington's disease (HD) is an incurable chronic neurodegenerative disorder that typically presents in mid-life with a range of motor, cognitive and affective problems. Patients are currently managed using a combination of drug treatments and non-pharmacological therapies but at present there is no "gold standard" treatment for any aspect of the disease.AREAS COVERED: In this review
