Surface Ruffles As Markers For Studies Of Cell Transformation By Rous Sarcoma Virus, Victor R. Ambros, Lan Bo Chen, John M. Buchanan
Surface Ruffles As Markers For Studies Of Cell Transformation By Rous Sarcoma Virus, Victor R. Ambros, Lan Bo Chen, John M. Buchanan
Victor R. Ambros
Confluent chick embryo fibroblasts infected with the Ts68 mutant of Rous sarcoma virus were examined by scanning electron microscopy at the permissive (36 degrees) and nonpermissive (41 degrees) temperatures for transformation. Infected cells shifted from 41 degrees to 36 degrees undergo a change in shape from elongated to rounded. This process is preceded by the appearance of surface ruffles on the cell. These surface ruffles are not observed on cells maintained at 41 degrees, appear as early as 0.5 hr after a shift to 36 degrees, and are common on cells maintained at 36 degrees. By 3.5 hr after the …

Removal Of Phosphorus From Static Sewage Effluent By Waterhyacinth, W Harold Ornes
Removal Of Phosphorus From Static Sewage Effluent By Waterhyacinth, W Harold Ornes
W. Harold Ornes
Waterhyacinth [Eichhornia crassipes (Mart.) Solms] was grown in static sewage effluent during May to July 1974 in outdoor concrete containers with a capacity of 760 liters and a surface area of 1.66 m². The plants were removed weekly from one-half of the surface area of the containers during 5-wk growth periods. Tissue phosphorus (P) and nitrogen (N), plant productivity, and some parameters of water quality were measured. A maximum uptake of 5,500 µg of P/g dry weight of plant material occurred when the level of orthophosphate phosphorus (available P) in the effluent was 1.1 µg/ml. Phosphorus in the effluent was …
