Infant feeding practices and reported food allergies at 6 years of age.

Objective: The goal of this study was to identify the frequency of physician-diagnosed food allergies among 6-year-old US children and study the impact of exclusive breastfeeding and complementary food introduction on this frequency.

Methods: Data were analyzed from children who participated in the Infant Feeding Practices Study II Year 6 Follow-Up Study (Y6FU). Children with probable food allergy (pFA) were defined as children with report of physician-diagnosed food allergy at age 6 years.

A high-throughput method for monitoring changes in homeobox gene expression.

Members of the homeobox gene superfamily of transcription factors are essential determinants of cellular identity during development. Their regulation and downstream gene targets are not well understood, however. This is due, in part, to the large number of genes that need to be analyzed simultaneously.

Acute toxicity of sodium arsenite in a complex food matrix.

Acute toxicity of a single oral dose of sodium arsenite (As), administered in half and half cream (HH), was assessed in male and non-pregnant female rats (0.41, 4.1, 41.

Maternal exposure to androstenedione does not induce developmental toxicity in the rat.

Thirty-day old female rats received corn oil or androstenedione (in corn oil) at one of four concentrations (5.0, 10.0, 30.

Characterization of Vibrio fluvialis-like strains implicated in limp lobster disease.

Studies were undertaken to characterize and determine the pathogenic mechanisms involved in a newly described systemic disease in Homarus americanus (American lobster) caused by a Vibrio fluvialis-like microorganism. Nineteen isolates were obtained from eight of nine lobsters sampled. Biochemically, the isolates resembled V.
