A 9,000-year record of Chagas' disease

TL;DR: The results suggest that the sylvatic (animal-infected) cycle of Chagas' disease was probably well established at the time that the earliest humans (members of the Chinchorro culture) first peopled this segment of the Andean coast and inadvertently joined the many other mammal species acting as hosts for this parasite.
Journal ArticleDOI

Serum Alpha-Fetoprotein and Human Chorionic Gonadotropin in Patients with Seminoma

TL;DR: An elevated alpha-fetoprotein level is firm evidence of the presence of non-seminomatous germ cell tumor and that the patient should be treated accordingly, however, if the level of human chorionic gonadotropin alone is elevated the diagnosis may be either non-Seminom atous tumor or seminoma.
Journal ArticleDOI

Mucinous adenocarcinoma of the renal pelvis. Report of two cases.

TL;DR: Two cases of mucinous adenocarcinoma of the renal pelvis are added to those so far reported in the literature and the frequency of long‐standing, chronic infection, and large renal calculi associated with this tumor is emphasized.
Journal ArticleDOI

Hybridization screening of very short PCR products for paleoepidemiological studies of Chagas' disease.

TL;DR: In this paper, a 70-nucleotide segment of ancient DNA from the kinetoplast of Trypanosoma cruzi, the infectious agent of Chagas' disease (American trypanosomiasis), was found to be present in soft tissue samples taken from four "naturally" mummified Andean bodies.
Journal ArticleDOI
