Cultured preadipose 3T3 cells are induced or enabled to undergo adipose conversion in the presence of an extract of pituitary gland. Adipogenic activity is found in standard growth hormone preparations derived from different species. Further purification of rat growth hormone by several methods does not remove its adipogenic activity. Human growth hormone… (More)
In this work, the chemical changes in calf thymus DNA samples were analyzed by X-ray photoelectron spectroscopy (XPS). The DNA samples were irradiated for over 5 h and spectra were taken repeatedly every 30 min. In this approach the X-ray beam both damages and probes the samples. In most cases, XPS spectra have complex shapes due to contributions of C, N,… (More)
