X-ray irradiation alters the actin cytoskeleton in murine lacrimal glands.

Objective: The aim of this study was to evaluate the effects of X radiation on the distribution of filamentous actin (F-actin) in the mouse exorbital lacrimal gland.

Materials And Methods: Mice were divided into groups that received no radiation (n = 6) or one single exposure of 36 mGy of X radiation (n = 12). The animals were sacrificed after 4, 8 or 24 h.

Clinical variability in KBG syndrome: report of three unrelated families.

The KBG syndrome is characterized by short stature, macrodontia, a specific combination of minor anomalies, developmental delay, and/or mental retardation. We reported on four patients from three unrelated families. The most frequent clinical findings were: atypical face, long/flat philtrum, thin upper lip, macrodontia, dental malposition, enamel hypoplasia, and cleft teeth.
