BACKGROUND: Electrogustometry is an accurate and increasingly popular method used to examine taste. However, its usefulness as a screening test is unknown. METHODS: We asked 114 subjects, some healthy but most with medical conditions possibly affecting taste, to rate their overall taste ability, on a scale of zero to 10. ...

In elderly persons, it is thought that maintenance of masticatory function may have a beneficial effect on maintenance of cerebral function. However, few studies on cerebral circulation during mastication exist. This study aimed to verify a possible increase in cerebral circulation and the presence of cerebral hemispheric dominance during gum ...

We have shown previously that an N-class ideal observer achieves the optimal receiver operating characteristic (ROC) hypersurface in a Neyman-Pearson sense. Due to the inherent complexity of evaluating observer performance even in a three-class classification task, some researchers have suggested a generally incomplete but more tractable evaluation in terms of ...

As gut capacity is assumed to scale linearly to body mass (BM), and dry matter intake (DMI) to metabolic body weight (BM(0.75)), it has been proposed that ingesta mean retention time (MRT) should scale to BM(0.25) in herbivorous mammals. We test these assumptions with the most comprehensive literature data collations ...

It is shown that the restrictions on the form of property tensors of rank <5 that follow from the Neumann principle for the point groups describing quasicrystals can easily be deduced from the restrictions for the point groups describing ordinary crystals. For octagonal and dodecagonal point groups, this is true ...

Although bycatch of industrial-scale fisheries can cause declines in migratory megafauna including seabirds, marine mammals, and sea turtles, the impacts of small-scale fisheries have been largely overlooked. Small-scale fisheries occur in coastal waters worldwide, employing over 99% of the world's 51 million fishers. New telemetry data reveal that migratory megafauna ...

The Barthel Index (BI) may underestimate disability change because its items have few response options. We examined whether a similar scale with more response options (Functional Independence Measure, FIM) was more responsive (n = 1,396). The FIM had greater potential for responsiveness and identified more people who changed. However, its ...

Exercise test was reported to be useful for some patients with periodic paralysis. We report here the results of exercise test in three cases of thyrotoxic periodic paralysis, for whom the exercise test was all positive. Exercise test could be one of the diagnostic tools in the "inter-attack" state of ...

STATING BACKGROUND: The clival angle, between the ethmoidal plane and the clival plane, measures the cranial base angulation. Relations between cranial base angulation and facial patterns have been discussed and present contradictory evidence. The aim of this study is to determine whether correlations could be found between the clival angle ...

Numerous studies report an increased frequency of minor physical anomalies (MPAs) in schizophrenic individuals compared with controls. However, these studies vary considerably regarding the magnitude of the case-control disparity and the topographical distribution of the anomalies. A meta-analysis was carried out on the existing MPA literature in an effort to ...

Two recent reviews have attempted to summarize findings quantitatively regarding assessment center (AC) construct-related validity (i.e., Lance, Lambert, Gewin, Lievens, & Conway, 2004; Lievens & Conway, 2001). Unlike these previous studies, which reanalyzed individual multitrait-multimethod (MTMM) matrices from previously published research, the authors recoded and combined past matrices into a ...

In the present study, a measure to assess the motivational qualities of music in exercise was redesigned, extending previous research efforts (Karageorghis et al., 1999). The original measure, the Brunel Music Rating Inventory (BMRI), had shown limitations in its factor structure and its applicability to non-experts in music selection. Redesign ...

We demonstrate that wetting effects at moving contact lines have a strong impact in viscous fingering patterns. Experiments in a rotating Hele-Shaw (HS) cell, dry or prewetted, show consistent morphological differences. When the wetting fluid invades a dry region, contact angle dynamics yield a kinetic contribution to the interface pressure ...

Few studies have examined the psychometrics of smoking-related behavioral measures in schizophrenia and questions have been raised about the applicability to smokers with schizophrenia. We examined the reliability of the Fagerström Test for Nicotine Dependence (FTND), Minnesota Nicotine Withdrawal Scale (M-NWS), and the Tiffany Questionnaire for Smoking Urges (TQSU) for ...

A brief semantic differential inventory intended to assess exercise-induced changes in feeling states was evaluated in applied settings. Concurrent validity was supported through significant correlations with scores on scales from the Exercise-induced Feeling Inventory which ranged from .33 to .49. Internal consistency (.93) was acceptable. The need for replication to ...
