Tracing the history of goat pastoralism: new clues from mitochondrial and Y chromosome DNA in North Africa.

Valuable insights into the history of human populations have been obtained by studying the genetic composition of their domesticated species. Here we address some of the long-standing questions about the origin and subsequent movements of goat pastoralism in Northern Africa. We present the first study combining results from mitochondrial DNA (mtDNA) and Y chromosome loci for the genetic characterization of a domestic goat population.

67Ga scintigraphy in B-cell non-Hodgkin's lymphoma: correlation of 67Ga uptake with histology and transferrin receptor expression.

Unlabelled: 67Ga scintigraphy is routinely used in the management of non-Hodgkin's lymphomas (NHLs), but the heterogeneity of 67Ga uptake in the different NHL histological subtypes has not been clearly explained. The transferrin receptors (TfR/CD71) play an important role in the mechanisms of 67Ga uptake by tumor cells. However, the relationship between the 67Ga uptake in NHL and the TfR/CD71 expression in lymphomatous cells remains to be defined.

Mechanism involved in gallium-67 (Ga-67) uptake by human lymphoid cell lines.

The gallium-67 (Ga-67) is a radionuclide used for diagnostic imaging. It is known for its ability to accumulate in inflammatory lesions and tumors, especially in lymphomas. The intracellular distribution and the uptake mechanism of Ga-67 remains a subject of discussion.
