Method of Developing a Culturally Tailored Diabetes Intervention for American Indians.

Background: American Indians have the highest prevalence of type 2 diabetes compared with any other racial or ethnic group.

Objective: Developing a culturally tailored diabetes prevention and management intervention is one way to reduce diabetes-related health disparities among American Indian populations. The purpose of this article is to describe our approach for developing a diabetes prevention and management intervention study using Kolb's Experiential Learning Theory as the framework.

High calcium transport by Polycystin-2 (TRPP2) induces channel clustering and oscillatory currents.

The regulation by Ca of Ca-permeable ion channels represents an important mechanism in the control of cell function. Polycystin-2 (PC2, TRPP2), a member of the TRP channel family (Transient Potential Receptor), is a Ca permeable non-selective cation channel. Previous studies from our laboratory demonstrated that physiological concentrations of Ca do not regulate in vitro translated PC2 (PC2) channel activity.

Case Report: Culture-negative Prosthetic Valve Endocarditis.

Background: Prosthetic valve endocarditis can be difficult to diagnose and cause significant morbidity and mortality, especially when no culture data are available to guide therapy. Transthoracic and transesophageal echocardiograms, the studies of choice for initial endocarditis evaluation, can be less reliable due to artifact and post-surgical changes. Some less common forms of endocarditis may be difficult to culture and, due to their fastidious nature, may delay the identification of causative organisms.

Tierra Del Fuego: What Is Left from the Precolonial Male Lineages?

Similar to other South American regions, Tierra del Fuego has an admixed population characterized by distinct ancestors: Native Americans who first occupied the continent, European settlers who arrived from the late 15th century onwards, and Sub-Saharan Africans who were brought to the Americas for slave labor. To disclose the paternal lineages in the current population from Tierra del Fuego, 196 unrelated males were genotyped for 23 Y-STRs and 52 Y-SNPs. Haplotype and haplogroup diversities were high, indicating the absence of strong founder or drift events.

Uniparental origins of the admixed Argentine Patagonia.

Objectives: We aimed to contribute to the understanding of the ancient geographic origins of the uniparentally inherited markers in modern admixed Argentinian populations from central Patagonia with new information provided for the city of Trelew. We attempted to highlight the importance of combining different genetic markers when studying population history.

Methods: The mtDNA control region sequence was typified in 89 individuals and 12 Y-STR and 15 Y-SNP loci were analyzed in 66 males.
