UNLABELLED Diabetes mellitus alters energy substrate metabolism and gene expression in the heart. It is not known whether the changes in gene expression are an adaptive or maladaptive process. To answer this question, we determined both the time-course and the extent of the alteration of gene expression induced by insulin-deficient diabetes. Transcript(More)
We have identified a discrete collagen-binding site within the Staphylococcus aureus collagen adhesin that is located in a region between amino acids Asp209 and Tyr233. Polyclonal antibodies raised against a recombinant form of the collagen adhesin inhibited the binding of collagen type II to S. aureus. When overlapping synthetic peptides mimicking segments(More)
The pcp gene, encoding a pyrrolidone carboxyl peptidase (PYRase), was cloned from a lambda GT11 genomic library prepared from Staphylococcus aureus FDA 574 and sequenced. The pcp gene is located 740 bp downstream from cna, a gene that encodes a collagen-binding adhesin in S. aureus. S. aureus pcp encodes a 212-amino-acid (aa) polypeptide. The pcp gene was(More)
Cervical cancer mortality is high in Texas, especially among Hispanic women living in south Texas and adjacent Mexico. Though human papillomavirus (HPV) infection has a causal role in the development of cervical cancer, there are no published data on the prevalence of HPV genotypes in this underscreened region. We studied 398 Hispanic women on both sides of(More)
Biological samples are an important part of investigating toxic exposures and disease outcomes. However, blood, urine, saliva, or hair can only reflect relatively recent exposures. Alternatively, deciduous teeth have served as a biomarker of early developmental exposure to heavy metals, but little has been done to assess organic toxic exposures such as(More)
Optimization of both sensitivity and ionization softness for the Hewlett-Packard particle-beam liquid chromatography-mass spectrometry interface has been achieved by using a statistical experimental design with response surface modeling. Conditions for both optimized sensitivity and ionization softness were found to occur at 55-lb/in.(2) nebulizer flow,(More)
