Twelve susceptible lambs inoculated with blood from the older lambs and 5 lambs inoculated with blood from the younger lambs reacted with fever and rickettsemia 2 5 days after blood transfusion.
Only Loomis conjures flesh and blood from the flimsy old journals and lifts the story from the pincers of the pack ice into the warm, fathomless and infinitely more thrilling realm of the human spirit.
Discharged in September 1864, having survived the battles of The Wilderness ("the most terrible 24 hours of our service in the war"), Cold Harbor ("How long will it take to whittle us away?"), Petersburg and many in between, Dawes wrote to his wife, Mary, from Washington, "I am fairly heart-sick at the stories of blood I hear from the old regiment.
For the bovine and porcine samples tested with blood from the 30 50 year old age group, lipopolysaccharide (LPS) at a concentration of 2 μg/ml was used as a positive control.
Young mice received blood from older mice, and old mice received blood from younger ones.
One of the more unusual approaches being tested is using blood from the young to reinvigorate the old.
We started out by systematic genome-wide surveys for new age-informative mRNA and DNA methylation markers in blood from the same young and old individuals using microarray technologies.
We measured DNA methylation at the IGF2/ H19 ICR in peripheral blood from the 315 17-year-old participants using the Sequenom MassARRAY EpiTYPER platform, which is based on bisulphite conversion of only non-methylated cytosines to uracil, base-specific cleavage (in this case, at the thymine base) and mass spectrometry.
Our previous study observed an elevated level of inflammatory chemokine CCL-4 in the blood from old individuals (Chiu et al., 2006).
For better comparison, it would have been important to test secondary lymphoid organs and peripheral blood from 12 14 week old mice.
