Two strains of measles virus IMA and SMD that were isolated using B95a cell line show hemadsorption negative. After adaptation to Vero cells, these strains gain
One EST N27741 with high expression in normal adult nasopharynx tissues but low expression in adult poorly differentiated squamous nasopharyngeal carcinoma has
The effects of simulated microgravity on cell growth and extracellular matrix of chondrocytes have been examined by a light microscope and a scanning electron m
Some remarkable FTIR spectral differences are observed and the differences at the molecular level are extracted between benign and malignant breast tissue sampl
Mg<sup>2+</sup>-induced changes in 77K fluorescence spectra of wheat thylakoid membranes were analyzed by a Gaussian deconvolution program. All spectra were fit
The mechanism of discontinuity behavior has important significance in the study of thermal science, such as fire, combustion, explosion and heat transfer. This
