Using the fixation insensitive NADPH-diaphorase reaction as a histochemical marker for the enzyme nitric oxide synthase (NOS), we investigated the possible sites of putatively NOS-related NADPH-diaphorase in the brain and retrocerebral complex of the cockroach, Diploptera punctata. In the cerebral ganglion, NADPH-diaphorase expression was localized in antennal lobes, optic lobes, mushroom bodie...

In South Africa, the main causal organisms of Fusarium head blight (FHB) are Gibberella zeae (=Fusarium graminearum), F. culmorum and F. crookwellense. Fusarium graminearum and F. culmorum are associated with warmer regions, and F. crookwellense with cooler regions. Sporadic FHB outbreaks occur principally in the irrigation areas of the country. In favourable years significant damage is caused....

as the basis for a re-evaluation of the relationship between religion and medicine in the middle ages. Historians have tended to study miracles from either a medical or a religious perspective, but McCleery convincingly argues that this is an anachronistic division and thus a more integrated approach is needed. She also demonstrates the potential of sociostatistical approaches to miracle collec...

The main objective of the present study was to isolate phytohormone-producing, phosphate-solubilizing strains of Azospirillum from wheat to be used as inoculants for plant growth promotion. Five Azospirillum strains were isolated from the rhizosphere of field-grown wheat (Triticum aestivum L.), and it was confirmed by BOX-polymerase chain reaction (PCR) that the isolates were different and not ...
