    Notes: Enkephalin appears to modulate several aspects of reproductive function in female rats. The purpose of this study was to determine if lactation influences preproenkephalin gene expression in one or more hypothalamic nuclei known to be involved in maternal or reproductive behavior and prolactin secretion. Lactating rats were killed on day 3 (LAC 3) or day 10 (LAC 10) of lactation. Controls consisted of regular 4-day cycling rats that were killed on diestrous day 1, with 9 to 12 females per group. We used in situ hybridization histochemistry to assess preproenkephalin gene expression in individual cells in the medial preoptic nucleus, anterior, medial and posterior arcuate nucleus, magnocellular and parvocellular aspects of paraventricular nucleus, and ventromedial nucleus. Preproenkephalin mRNA in the anterior arcuate nucleus increased to reach significance (P 〈 0.05) at day 10 of lactation. Levels in the medial arcuate nucleus increased significantly (P 〈 0.001) by day 3 of lactation (LAC 3) and remained elevated on day 10 (LAC 10). No significant differences between lactating and control rats were detected in preproenkephalin mRNA levels in the posterior arcuate nucleus, medial preoptic nucleus or in the ventromedial nucleus. Substantial levels of preproenkephalin mRNA were found in the paraventricular nucleus, particularly in a limited region of the magnocellular portion. However, these levels did not change with lactation. These data provide evidence for differential regulation of the preproenkephalin gene during lactation. This change may contribute to. lactational hyperprolactinemia and suppressed GnRH secretion, leading to reproductive acyclicity.

    Notes: Abstract Recruiting is a critical staffing activity for organizations, but its impact on the job seeker is poorly understood. Much remains to be learned about individual differences in reactions to recruitment efforts. This paper discusses the results of a study of MBA candidates that examined (a) the relative importance of various job, organizational, diversity, and recruiter characteristics on assessments of organizational attractiveness, and (b) the extent to which these assessments differed when applicant race and gender are taken into account. Results confirmed that relative to organizational, diversity, and recruiter characteristics, job factors were reported as most important to organizational attraction. However, within the job, diversity, and recruiter characteristics categories interesting gender and/or race differences emerged. The implications of these differences for research and for practices are offered.
