While prior studies have examined sleep across the lifecourse, few studies have investigated sleep around the birth of a child, one of the most important events to cause sleep deprivation. This study investigates changes in sleep hours and quality, paying attention to differences by gender and partnership status. Using the UK Household Longitudinal Study, we follow approximately 1,000 participants as they transition into parenthood in a three-year window.

However, over the past fifty years, modernisation in Asia has been accompanied by a remarkable drop in birth rates to a level even lower than most western countries. Prior research on western nations has shown that the time demands and financial stresses of parenthood, as well as current inflexible employment practices, contribute to the high cost of parenthood and discount the emotional rewards of having children.

This study followed youth in the National Longitudinal Survey of Youth 1979 and 1997 cohorts ( = 12,686 and 8,984, respectively) from 16 to 32 years old to investigate this trend in the United States, examining cross-cohort changes in transitions with a focus on differences by family background. Logistic regressions revealed that young adults in the most recent cohort were less likely to have completed schooling, fully entered the labor force, married, or become parents by their 30s than those in the older cohort.

Studies have demonstrated that cisplatin (CDDP) induced CEBPD expression and had led to chemotherapeutic drug resistance. However, the underlying molecular mechanisms of CDDP-regulated CEBPD expression and its relevant roles in CDDP responses remain elusive.

Still, the mechanisms and critical pathways that contribute to chemotherapy resistance are relatively unknown. This study elucidates the chemoresistance-associated pathways retrieved from the integrated biological interaction networks and identifies signature genes relevant for chemotherapy resistance.

Background: Modeling cancer-related regulatory modules from gene expression profiling of cancer tissues is expected to contribute to our understanding of cancer biology as well as developments of new diagnose and therapies. Several mathematical models have been used to explore the phenomena of transcriptional regulatory mechanisms in Saccharomyces cerevisiae. However, the contemplating on controlling of feed-forward and feedback loops in transcriptional regulatory mechanisms is not resolved adequately in Saccharomyces cerevisiae, nor is in human cancer cells.
