Diurnal variations in serum testosterone levels were studied in six adult maleMacaca radiata. Though the testosterone levels fluctuated considerably during the 24-hr period, a distinctive diurnal pattern characterized
by lower concentrations during day hours and higher concentrations during night hours was observed. 相似文献

Circulating Cell-Free DNA from Colorectal Cancer Patients May Reveal High KRAS or BRAF Mutation Load

Our data might suggest a very high variation in the proportion of malignant cells in colorectal tumors and/or low tumor cell clonogenicity. However, the direct relationship between these data and the proportion of malignant cells is currently uncertain as the mechanism of ccfDNA release determines the yield (necrosis, apoptosis, or active release). Therefore, interindividual comparison of the proportion of mutant allele determined from circulating DNA could appear somewhat more difficult to interpret; however, this parameter could be an efficient biomarker for monitoring or following up CRC patients and could be combined with size fraction analysis, as demonstrated in this study, to provide a deeper examination toward this goal. 相似文献
