Travelling to the south: Phylogeographic spatial diffusion model in Monttea aphylla (Plantaginaceae), an endemic plant of the Monte Desert.

Effects of Pleistocene climatic oscillations on plant phylogeographic patterns are relatively well studied in forest, savanna and grassland biomes, but such impacts remain less explored on desert regions of the world, especially in South America. Here, we performed a phylogeographical study of Monttea aphylla, an endemic species of the Monte Desert, to understand the evolutionary history of vegetation communities inhabiting the South American Arid Diagonal. We obtained sequences of three chloroplast (trnS-trnfM, trnH-psbA and trnQ-rps16) and one nuclear (ITS) intergenic spacers from 272 individuals of 34 localities throughout the range of the species.

Neonatal administration of high-dose intravenous immunoglobulin in rhesus hemolytic disease.

Our aim was to assess the effectiveness of neonatal treatment of Rh hemolytic disease with high-dose intravenous immunoglobulin (HDIVIG), in reducing neonatal hemolysis. A total of 40 neonates born to isoimmunized Rh negative women were studied. The population was randomized into 2 groups: Group 1 received IVIG 800 mg/kg/day for 3 days, plus phototherapy; and Group 2 received only phototherapy.

Limb salvage therapy for soft tissue sarcomas of the foot.

From 1974 to 1988, 20 patients with soft tissue sarcomas of the foot underwent attempted limb preservation at UCLA. Eighteen patients had localized tumor and two had metastases. Sixteen patients had previously untreated tumors and four patients had experienced 2-4 local recurrences before definitive management.
