The localization of V", gene regions to chromosome 2, on which the K locus is located, and to other chromosomes is described. The V", genes that have been transposed to other chromosomes are called orphons. The finding of two new V", genes on chromosome 22 is reported. A V", 11 gene of this region and two V", I genes of the Chr 1 and the cos 118 regions were sequenced. The two V", I orphon sequ...

A child with unilateral radial aplasia, asymmetry, other malformations, and severe physical and mental retardation is reported. In blood and bone marrow cultures a low mosaicism for trisomy 22 was found. In a few cells a chromosome 22 was missing. The importance of early cytogenetic analysis on large numbers of cells is emphasised, especially in cases of asymmetry where mosaicism is suspected.

this study is due to investigate the histological and histochemical properties of the tongue of the embryo and one day old ostrich chickens. twelve eggs in various embryonic stages (22, 26, 30 and 36 embryonic days) and three one day chicks were used. the specimens from whole of tongue were collected and after preparing tissue were stained by histological staining methods include h & e,masson t...

In this experiment, 0, 0.125, 0.25, 0.5, and 1.0 ml of each oil dissolved in 1 ml of 95 % ethanol was added to 1 kg of soil containing 370 P. penetrans per kg, and incorporated by shaking. After 10 days at 22 ± 3 C, a four-week-old tomato (Lycopersicon esculentum Mill cv. Bonny Best) seedling was planted in each of six 5-cm-diam plastic pots containing 100 g of treated or untreated infested soi...
