Social support and active coping were significant predictors of adaptation to college, whereas locus of control was not. However, there was an interaction between ethnicity and locus of control indicating that although internal African American, Latino, and white students had higher adaptation-to-college scores than external students, the opposite was true for Asian Americans. The relationships among social support, internality, and active coping were also explored. Satisfaction with social support and internality were positively related to active coping, but locus of control and social support were unrelated. Active coping and internality were significantly related to each other for all groups except for African Americans. Although most relationships were the same across groups, these findings call attention to the role of ethnicity as a moderator of college adjustment processes.

The period of medical follow-up, or ‘watchful waiting’, to monitor for regression or progression of the lesion before deciding if treatment by conisation is necessary can be long. The aim of this study was to examine the experiences of women with different stages of cervical dysplasia and to examine whether their knowledge of human papillomavirus (HPV) as the cause of cervical dysplasia influenced their perception of their disease. Subject and methods We used focus group and individual interviews with 12 women diagnosed with different stages of cervical dysplasia—women who had and had not been conised. Interview guides were prepared on the basis of a literature review that identified important issues and questions for the participants. Results The participants considered cervical dysplasia to be a highly distressing condition and experienced monitoring as a worrying delay before regression of the lesions or treatment could be initiated. Women expressed a fear of cancer that was not proportional to the stage of their dysplasia, but was determined by their degree of knowledge about their condition. Unlike other sexually transmitted diseases, information about HPV did not result in stigmatisation as the perception of this disease was dominated by cancer. Conclusion This study showed that it is extremely important to address women’s fears, their need for information and to ensure better communication with medical practitioners about cervical dysplasia immediately after diagnosis, irrespective of the disease stage.

Breeding of barley (Hordeum vulgare L.) for R. padi resistance shows that there are several resistance genes, reducing aphid growth. To identify candidate sequences for resistance-related genes, we performed microarray analysis of gene expression after aphid infestation in two susceptible and two partially resistant barley genotypes. One of the four lines is a descendant of two of the other genotypes. There were large differences in gene induction between the four lines, indicating substantial variation in response even between closely related genotypes. Genes induced in aphid-infested tissue were mainly related to defence, primary metabolism and signalling. Only 24 genes were induced in all lines, none of them related to oxidative stress or secondary metabolism. Few genes were down-regulated, with none being common to all four lines. There were differences in aphid-induced gene regulation between resistant and susceptible lines. Results from control plants without aphids also revealed differences in constitutive gene expression between the two types of lines. Candidate sequences for induced and constitutive resistance factors have been identified, among them a proteinase inhibitor, a serine/threonine kinase and several thionins.

Results of recent projects and programmes focused on children's health underline a specific vulnerability of children to environmental genotoxicants. Environmental research on children predominantly investigates the health effects of air pollution while effects from radiation exposure deserve more attention. The main sources of knowledge on genome damage of children exposed to radiation are studies performed after the Chernobyl nuclear plant accident in 1986. The present review presents and discusses data collected from papers analyzing genome damage in children environmentally exposed to ionizing radiation. Overall, the evidence from the studies conducted following the Chernobyl accident, nuclear tests, environmental radiation pollution and indoor accidental contamination reveals consistently increased chromosome aberration and micronuclei frequency in exposed than in referent children. Future research in this area should be focused on studies providing information on: (a) effects on children caused by low doses of radiation; (b) effects on children from combined exposure to low doses of radiation and chemical agents from food, water and air; and (c) specific effects from exposure during early childhood (radioisotopes from water, radon in homes). Special consideration should also be given to a possible impact of a radiochemical environment to the development of an adaptive response for genomic damage. Interactive databases should be developed to provide integration of cytogenetic data, childhood cancer registry data and information on environmental contamination. The overall aim is to introduce timely and efficient preventive measures, by means of a better knowledge of the early and delayed health effects in children resulting from radiation exposure.
