Plesiomonas shigelloides hugZ encodes an iron-regulated heme binding protein required for heme iron utilization.

Plesiomonas shigelloides is an intestinal pathogen that uses heme as an iron source. The P. shigelloides heme utilization system consists of 10 genes, 7 of which permit heme transport and 3 of which are associated with utilization of heme as an iron source once it is inside the cell.

Characterization of the SCP/TAPS gene family in Drosophila melanogaster.

The SCP/Tpx-1/Ag5/PR-1/Sc7 (SCP/TAPS) gene family encodes proteins found in many eukaryotes. SCP/TAPS proteins are defined by the presence of an SCP/TAPS domain, and many participate in important physiological processes. Five SCP/TAPS genes were previously identified in Drosophila melanogaster and are expressed in the digestive tract or in the testes.

Drugs and substances: views from a Latino community.

The last three decades have seen an increase in the study of licit and illicit substance use and abuse. Very few studies, however, have been conducted to show the views of minority people on what substance abuse really is and how it affects their families and communities, although connections have often been made between crime and minority involvement in drug trafficking, use and abuse. This exploratory study presents an attempt to explore Latino or Hispanic people's perceptions and attitudes regarding the use and abuse of both licit and illicit substances, in a Texas City.
