Two surveys of maternal mortality conducted in Egypt, in 1992-93 and in 2000, collected data from a representative sample of health bureaus covering all of Egypt, except for five frontier governorates which were covered only by the later survey, usin

We have detected a plant beta-glucuronidase activity, present in several tissues and organs of plant species belonging to different families. The fluorimetric beta-glucuronidase assay was used to partially characterize this activity in post-ribosomal

Microspores and young pollen grains can be isolated from the anther and matured in vitro. Pollination with in vitro matured pollen leads to seed set. This technique has potential applications in plant breeding. During in vitro maturation, the pollen

Formation of pollen in angiosperms takes place in the anthers, the male sexual organs. During normal male gametophytic development in vivo, each diploid microspore mother cell generates, through meiosis, four haploid microspores; after one or two mit

In most transformation systems today, in vitro regeneration of plants is an essential step and very often the main limiting factor for yield and success. Circumvention of in vitro regeneration would therefore be highly advantageous. The simplest way

Immature tobacco (Nicotiana tabacum L.) pollen has been isolated from anthers in three distinct stages of development, including the microspore stage. In in-vitro cultures, fully functional, mature pollen was obtained. In a germination medium, this p

Anther culture is one of the few biotechnologies which has found its way into breeding practice. Still however, many species are recalcitrant and yields are low, indicating that the mechanisms by which immature male gametophytes change their developm
