We report on 2 infants, one with a bilateral and the other with a unilateral corneal metaplasia. The first case with bilateral corneal metaplasia showed shortening of both upper and lower lids with formation of symblephara. By ultrasonography the right eye presented with microphthalmos, aphakia, and persistent hyaloid, whereas the inner parts of the left eye appeared to be normal. The question ...

Activin has long-range effects in Xenopus development, inducing the mesodermally expressed brachyury gene up to 10 cell diameters from a localised source. Recent experiments show that activin diffuses through tissues to establish a morphogen gradient, and that the long-range effects are a direct result of activin signalling.

A 5-month-old boy with bilateral sclero-cornea, multiple systemic abnormalities, and normal karyotype had his left eye removed after corneal perforation. Histopathological examination of the enucleated eye revealed an irregular corneal epithelium, absent Bowman's membrane, thickened and vascularized stromal lamellae, absent Descemet's membrane and endothelium, no angle structures, hypoplasia of...

the aim of this study was to determine the prognosis and survival for patients with borderlineovarian tumor (bot). a retrospective review of 30 patients with serous andmucinous bot treated at or referred to our institution was performed. fifteenpatients (50%) had serous, and the others had mucinous bot. about 86% of allpatients in both groups were in stage i of the disease. the recurrent diseas...

Cells were isolated from the somite mesoderm and from the unsegmented (presomite) mesoderm of early chick embryos and exposed to actinomycin D in single cell culture. Actinomycin D inhibited proliferation in cell cultures derived from the unsegmented mesoderm, although the same concentrations of this antibiotic did not inhibit cultures derived from the somite mesoderm. This differential sensiti...
