Slow virus kidney disease of mice   总被引：7，自引：0，他引：7  

F D Baker  J Hotchin 《Science (New York, N.Y.)》1967,158(800):502-504

Preliminary observations based on organ weight differential, renal function, and glomerular lesions in mice infected neonatally with lymphocytic choriomeningitis indicate the presence of a slow virus-induced kidney disease of mice. This condition is accompanied by a marked decrease in the size of the kidneys, with progressive diminution of renal function, as shown by measurements of creatinine and urea clearance.  相似文献   

Nimbus-7 coastal zone color scanner: system description and initial imagery     

Hovis WA  Clark DK  Anderson F  Austin RW  Wilson WH  Baker ET  Ball D  Gordon HR  Mueller JL  El-Sayed SZ  Sturm B  Wrigley RC  Yentsch CS 《Science (New York, N.Y.)》1980,210(4465):60-63

The Coastal Zone Color Scanner (CZCS) on Nimbus-7, launched in October 1978, is the only sensor in orbit that is specifically designed to study living marine resources. The initial imagery confirms that CZCS data can be processed to a level that reveals subtle variations in the concentration of phytoplankton pigments. This development has potential applications for the study of large-scale patchiness in phytoplankton distributions, the evolution of spring blooms, water mass boundaries, and mesoscale circulation patterns.  相似文献   

The imaging photopolarimeter experiment on pioneer 11

For 2 weeks continuous imaging, photometry, and polarimetry observations were made of Jupiter and the Galilean satellites in red and blue light from Pioneer 11. Measurements of Jupiter's north and south polar regions were possible because the spacecraft trajectory was highly inclined to the planet's equatorial plane. One of the highest resolution images obtained is presented here along with a comparison of a sample of our photometric and polarimetric data with a simple model. The data seem consistent with increased molecular scattering at high latitudes.  相似文献   

Spatial patterns in the distribution of tropical tree species   总被引：1，自引：0，他引：1

Fully mapped tree census plots of large area, 25 to 52 hectares, have now been completed at six different sites in tropical forests, including dry deciduous to wet evergreen forest on two continents. One of the main goals of these plots has been to evaluate spatial patterns in tropical tree populations. Here the degree of aggregation in the distribution of 1768 tree species is examined based on the average density of conspecific trees in circular neighborhoods around each tree. When all individuals larger than 1 centimeter in stem diameter were included, nearly every species was more aggregated than a random distribution. Considering only larger trees (>/= 10 centimeters in diameter), the pattern persisted, with most species being more aggregated than random. Rare species were more aggregated than common species. All six forests were very similar in all the particulars of these results.  相似文献   

Mutations in dynein link motor neuron degeneration to defects in retrograde transport

Degenerative disorders of motor neurons include a range of progressive fatal diseases such as amyotrophic lateral sclerosis (ALS), spinal-bulbar muscular atrophy (SBMA), and spinal muscular atrophy (SMA). Although the causative genetic alterations are known for some cases, the molecular basis of many SMA and SBMA-like syndromes and most ALS cases is unknown. Here we show that missense point mutations in the cytoplasmic dynein heavy chain result in progressive motor neuron degeneration in heterozygous mice, and in homozygotes this is accompanied by the formation of Lewy-like inclusion bodies, thus resembling key features of human pathology. These mutations exclusively perturb neuron-specific functions of dynein.  相似文献
