Informational masking (IM) refers to elevations in signal threshold caused by masker uncertainty. The purpose of this study was to investigate two factors expected to influence IM in hearing-impaired listeners. Masked thresholds for a 2000-Hz signal in the presence of simultaneous multitone maskers were measured in 16 normal-hearing (NH) and 9 hearing-impaired (HI) listeners. The maskers were 7...

Introduction There has been a continuous increase in the incidence of major lower limb amputations from the beginning of the century until the mid-1980s (Table 1). This increase has been attributed to the increasing number of elderly persons, diabetics and smokers (Liedberg and Persson, 1983). During the last decade, several reports from Scandinavia have mentioned a decreased incidence of major...

BACKGROUND Strigolactones (SLs) - a group of plant hormones and their derivatives - have been found to play a role in the regulation of root development, in addition to their role in suppression of lateral shoot branching: they alter root architecture and affect root-hair elongation, and SL signalling is necessary for the root response to low phosphate (Pi) conditions. These effects of SLs have...

Strigolactones (SLs) are a new class of plant hormones whose role has been recently defined in shoot branching, root development and architecture, and nodulation. They are also active in the rhizosphere as signalling molecules in the communication between plants, AMF (arbuscular mycorrhizal fungi) and parasitic weeds. In spite of the crucial and multifaceted biological role of SLs, the current ...
