Efficacy of Rapamycin as Inducer of Hb F in Primary Erythroid Cultures from Sickle Cell Disease and β-Thalassemia Patients.
2015
Phenotypic improvement of hemoglobinopathies such as sickle cell disease and β-thalassemia (β-thal) has been shown in patients with high levels of Hb F. Among the drugs proposed to increase Hb F production, hydroxyurea (HU) is currently the only one proven to improve the clinical course of these diseases. However, Hb F increase and patient's response are highly variable, indicating that new pharmacological agents could be useful for patients not responding to HU or showing a reduction of response during long-term therapy. In this study we evaluated the efficacy of rapamycin, a lypophilic macrolide used for the prevention of acute rejection in renal transplant recipients, as an inducer of Hb…
Correlation of the chemiluminescence-activity of peripheral blood monocytes with CSF parameters of inflammation and the clinical course of patients w…
2009
– The chemiluminescence-activity (CL-A) of peripheral blood monocytes (MO) was measured in eight patients with lymphocytic meningitis or meningoencephalitis and compared to CSF parameters and the clinical course. The initial maximum CL-A was around four times above the control and decreased to normal values within approximately 20 days. Poor correlations were found when the CL-A was compared to CSF parameters in the total group of patients. With regard to the CSF parameters in individual patients the CL-A was closely related to the cell count, to a lesser degree to the protein content, but not to the IgG content. Finally, a very good correlation of the CL-A was found with the clinical cours…
Clinical course of rhinitis and changes in vivo and in vitro of allergic parameters in elderly patients: a long-term follow-up study
2012
Changes in rhinitis symptom severity tend to decrease with aging, but whether the decrease is associated with allergic skin test reactivity, serum total and specific IgE, and nasal eosinophils or determined only by aging is poorly understood. The aim of the study was to analyze sensitivity in vivo and in vitro some 15 years after primary testing, skin prick test (SPT), serum total and specific IgE, ratio sIgE/tIgE, and nasal eosinophils in order to evaluate changes due to age and changes due to the severity of rhinitis symptoms. One hundred and eight rhinitis patients who had been investigated in 1995 were re-interviewed and their current allergy re-assessed after a follow-up of 15 years. A…
Time course of human 40 Hz EEG activity accompanying P3 responses in an auditory oddball paradigm
1997
In order to quantify the time course of auditory P3-related gamma activity, root mean square (RMS) values were calculated from band-filtered (30-45 Hz) target and non-target responses in an auditory oddball experiment. Evoked (phase locked) gamma activity was evaluated from the time domain averages, whereas induced (not necessarily phase locked) activity was analyzed on the basis of single trials. Gamma RMS values were integrated across different time windows, namely the prestimulus, N50/P50, N100, pre P3, P3 and post P3 window. The single trial P3 window hereby was defined by a maximum amplitude criterion. In accordance with other studies, we found a pronounced increase of evoked gamma act…
Towards optimal clinical and epidemiological registration of haematological malignancies: Guidelines for recording progressions, transformations and …
2015
AbstractHaematological malignancies (HM) represent over 6% of the total cancer incidence in Europe and affect all ages, ranging between 45% of all cancers in children and 7% in the elderly. Thirty per cent of childhood cancer deaths are due to HM, 8% in the elderly. Their registration presents specific challenges, mainly because HM may transform or progress in the course of the disease into other types of HM. In the context of cancer registration decisions have to be made about classifying subsequent notifications on the same patient as the same tumour (progression), a transformation or a new tumour registration. Allocation of incidence date and method of diagnosis must also be standardised…
Topicality matters: Position-specific demands on Chinese discourse processing
2011
We report an event-related potential study designed to explore the nature of context-induced topicality in Chinese discourse processing. Topic is what an utterance is about and represents the most prominent discourse element, which occurs sentence-initially in Chinese. We tested question-answer pairs consisting of topic and non-topic questions followed by different continuations (Topic-Continuity, Topic-Shift, Novel-Topic). ERPs were measured at distinct sentential positions and revealed that sentence-initially information processing is guided by topicality, which affects N400 and Late Positivity effects alike. In non-initial positions, the given-new distinction is the dominant principle, a…
Animacy matters: ERP evidence for the multi-dimensionality of topic-worthiness in Chinese
2013
Abstract An event-related potential (ERP) study was conducted to investigate how animacy interacts with givenness during topic processing. Both animacy and givenness have been considered as within-discourse factors that contribute to an element׳s potential to form an optimal topic (i.e., topic-worthiness). ERPs were recorded while participants read question–answer pairs, of which the target sentence induced either a continuation or an alternation of a previously introduced topic (i.e., given vs. new). Depending on the context, a potential topic further differed in its animacy from the preceding one (i.e., animate vs. inanimate). The data revealed a robust givenness effect with an N400 reduc…
Separable neural bases for subprocesses of recognition in working memory.
2011
Working memory supports the recognition of objects in the environment. Memory models have postulated that recognition relies on 2 processes: assessing the degree of similarity between an external stimulus and memory representations and testing the resulting summed-similarity value against a critical level for recognition. Here, we varied the similarity between samples held in working memory and a probe to investigate these 2 processes with magnetoencephalography. Two separable components matched our expectations: First, from 280 ms after probe onset, clearly nonmatching probes differed from both similar nonmatches and matches over left frontal cortex. At 350--400 ms, these signals evolved i…
Physiotherapists' accounts of their clients in geriatric inpatient rehabilitation.
2008
This article aims to describe how physiotherapists working with frail older people talk about their clients. Semi-structured qualitative interviews with physiotherapists (n = 11) were audio recorded, transcribed and analysed using discourse analysis. Two accounts were identified: (i) older adults as recipients of a treatment intervention at the rehabilitation centre, with the dimensions 'a focus on physical impairments' and 'a focus on social needs' and (ii) older adults as partners in an exercise intervention to support their everyday living at home. Older adults' everyday living context was not considered in the approach where, in an isolated and objectified manner, the physiotherapists f…
The facilitative effect of gestures on the neural processing of semantic complexity in a continuous narrative
2019
© 2019 Elsevier Inc. Gestures are elemental components of social communication and aid comprehension of verbal messages; however, little is known about the potential role of gestures in facilitating processing of semantic complexity in an ecologically valid setting. The goal of this study was to investigate whether cognitive load, as indexed by semantic complexity, is modulated by the presentation of gestures accompanying speech. Twenty healthy participants watched 16 video clips of a short narrative while instructed to carefully listen to and watch the narrator while functional magnetic resonance imaging (fMRI) data were acquired. The videos contained passages with and without various co-s…
