Parenting perceptions of low-income mothers.

Purpose: The purpose of this descriptive qualitative study was to gain understanding of perceptions of low-income pregnant women and mothers about parenting.

Study Design And Methods: Participants were 65 low-income, primarily African American, women in their 20s and 30s who were recruited from a faith-based social service center in Memphis, Tennessee. Interviews were conducted by nursing, social work, and psychology students.

Enhancer-dependent 5'-splice site control of fruitless pre-mRNA splicing.

The Drosophila fruitless (fru) gene encodes a transcription factor that essentially regulates all aspects of male courtship behavior. The use of alternative 5'-splice sites generates fru isoforms that determine gender-appropriate sexual behaviors. Alternative splicing of fru is regulated by TRA and TRA2 and depends on an exonic splicing enhancer (fruRE) consisting of three 13-nucleotide repeat elements, nearly identical to those that regulate alternative sex-specific 3'-splice site choice in the doublesex (dsx) gene.

Protein denitration/modification by Escherichia coli nitrate reductase and mammalian cytochrome P-450 reductase.

The incubation of peroxynitrite (PN)-pretreated histone III-S (NH) with Escherichia coli nitrate reductase (cytochrome, NADPH/GSH-independent) and that of NADPH-treated NH (NHNADPH) with liver cytochrome P-450 reductase (NADPH-dependent) resulted in decreased 3-nitrotyrosine immunoreactivity found in Western blot analysis. Additionally, increased nitrate was noted as an end product of these reactions. These findings imply that varied enzymatic denitration/modification of NO/PN-reacted protein, either with or without a reductant, may be important in regulating related signal transduction cascade(s) and relieving oxidative stress.
