The high-affinity radioligand [(18)F]fallypride (FP) is frequently used for quantification of striatal/extrastriatal D(2/3) receptors and the receptor occupancies of antipsychotics (APs). Its 110 minutes half-life allows long scan durations. However, the optimum scan duration is a matter of debate. This investigation focuses on scan-duration-related effects(More)
Adverse skin reactions cover many types of response: toxic, irritant, allergic, urticarial, sensory, etc. The relationships between an individual's tendency to develop different types of skin response are not well-described. We examined whether those who perceive stinging might be more likely to experience urticarial, sensory and irritation reactions in(More)
There exists within the population subsets of individuals who display heightened skin reactivity to materials the majority find tolerable. In a series of investigations, we have examined interrelationships between many of the endpoints associated with the term 'sensitive skin'. In the most recent work, 58 volunteers were treated with 10% lactic acid, 50%(More)
The high affinity radioligand [18F]fallypride (FP) is a frequently used tracer for D2/3-receptor visualization. Due to its high affinity, some extrastriatal region (e.g. temporal cortex, ACC, or thalamus) can be quantified. As substituted benzamide, FP is selective for D2/3-receptors. The long half-life of fluorine-18 labeling allows comparatively long scan(More)
The impact of many human variables on the response to skin irritating substances has been studied to varying degrees, including the impact of age, sex, and atopic status. However, the importance of ethnic origin has been more difficult to investigate, leading to a relative paucity of compelling data, either for or against the existence of differences. A(More)
INTRODUCTION Acute Respiratory Infections (ARI) are responsible for nearly two million childhood deaths worldwide. A limited number of studies have been published on the epidemiology of viral respiratory pathogens in Egypt. METHODS A total of 6113 hospitalized patients >1 month of age with suspected ARI were enrolled between June 23, 2009 and December 31,(More)
The elderly patients were underrepresented in outpatient psychotherapy, is returned in the clinical literature on the reluctance and skepticism of psychotherapists. In the study presented here, psychotherapists were asked how they perceive the elderly, the attitudes they have towards them and what factors it depends on how many older people a(More)
1. The survey and the experiment Cultural Changes in the Netherlands is a longitudinal survey in which a representative sample of the Dutch population aged 16 and over is interviewed at regular intervals. The survey was carried out annually until 1998, since when it has been held every two years. The aim of the project is to construct opinion time series.(More)
