“Several wood samples collected from Dorslandboom, a large iconic African baobab (Adansonia digitata L.) from Namibia, were investigated by AMS radiocarbon dating subsequent to pretreatment and, alternatively, without pretreatment. The comparative statistical evaluation of results showed that there were no significant differences between fraction modern values and radiocarbon dates of the samples analyzed after pretreatment and without pretreatment, respectively. The radiocarbon date of the oldest sample was 993 +/- 20 BP. Dating results also revealed that Dorslandboom is a multi-generation AZD8055 tree, with several stems showing different ages.

“A new genus and species BIBF 1120 purchase of ankylosaurid, a dinosaur from the Upper Cretaceous of the Gobi Desert has been described. It shows characters typical of many Late Cretaceous ankylosaurs. The new specimen is a virtually complete skull with both hemimandibles preserved intact with the predentary. This skull has been subjected to almost no crushing or shearing. It has an equilateral, triangular-shaped skull when viewed dorsally and large, highly ornamented narial osteoderms, which give the skull a bull-like appearance with flaring nostrils. Braincase

features are more primitive than those of the other Gobi Desert ankylosaurs.”
“As our understanding of the basic precepts of immunobiology continue to advance at a rapid pace, translating such discoveries into meaningful therapies for patients has proved challenging. This is especially apparent in the use of cytokine-based immunotherapies for cancer. Unanticipated and serious Galardin cell line side effects, as well as low objective response rates seen in clinical trials, have dealt setbacks to the field. Granulocyte-macrophage colony-stimulating factor (GM-CSF) and common gamma-chain (gamma-c) interleukins are cytokines that have been used as stand-alone immunotherapies with moderate success. Our group has found that the fusion of GM-CSF to members of gamma-c interleukins results in the generation of novel proteins with unique signaling properties and unheralded biological effects. These fusion proteins, termed GIFT (GM-CSF interleukin fusion transgenes) fusokines, are the result of combining GM-CSF and a gamma-c interleukin into a single, bifunctional polypeptide. In our experience, GIFT fusokines often confer immune cells with a gain of function that cannot be explained by the mere sum of their constituent moieties. They act as bispecific ligands, coupling activated GM-CSF and interleukin receptors together to drive unique downstream signaling events.
