Cleft and Craniofacial Mission Care: Management of Facial Clefts: International Missions.

This article guides readers in the venture of creating, funding, or volunteering with a facial-cleft mission treatment team. This outline is intended to emphasize longitudinal care for all patients. Advanced planning is key to mission success.

Collisionally processed rocks on mars.

The Pathfinder landing site on Mars has boulders that may be cratered (Stimpy), split (Chimp), fragmented (Book End and Flat Top), or otherwise partly destroyed (Yogi and Frog) by collisional processes. Atmospheric-entry calculations show that centimeter-sized projectiles survive passage through the martian atmosphere and encounter the surface of Mars at velocities of a few kilometers per second. Craters less than 1 meter in diameter may contribute to the evolution of the martian surface and its soils.

Scatter factor/hepatocyte growth factor as a regulator of skeletal muscle and neural crest development.

Factors that regulate cellular migration during embryonic development are essential for tissue and organ morphogenesis. Scatter factor/hepatocyte growth factor (SF/HGF) can stimulate motogenic and morphogenetic activities in cultured epithelial cells expressing the Met tyrosine kinase receptor and is essential for development; however, the precise physiological role of SF/HGF is incompletely understood. Here we provide functional evidence that inappropriate expression of SF/HGF in transgenic mice influences the development of two distinct migratory cell lineages, resulting in ectopic skeletal muscle formation and melanosis in the central nervous system, and patterned hyperpigmentation of the skin.

Isolation of a novel receptor cDNA establishes the existence of two PDGF receptor genes.

A genomic sequence and cloned complementary DNA has been identified for a novel receptor-like gene of the PDGF receptor/CSF1 receptor subfamily (platelet-derived growth factor receptor/colony-stimulating factor type 1 receptor). The gene recognized a 6.4-kilobase transcript that was coexpressed in normal human tissues with the 5.
