Maternal basking regime can affect gestation length in viviparous squamates, but effects on offspring phenotype in species with extended pregnancies and ability to delay the birth season are unclear. We investigated the effects of three maternal basking regimes on maternal thermoregulation, gestation length, pregnancy outcome and offspring phenotype in the gecko Woodworthia 'Otago/Southland'. T...
BACKGROUND Multiple studies have suggested a relationship between adult exposures to environmental organochlorines and fecundability. There is a paucity of data, however, regarding fetal exposure to organochlorines via the mother's blood and fecundability of adult female offspring. METHODS Data from a two-generation cohort of maternal fisheaters was investigated to assess female offspring fec...
Understanding the developmental origins of congenital capabilities such as sucking is fundamental knowledge that can contribute to improving the clinical management of early feeding and facilitate the onset of oral ingestion. We describe analyses in rats showing that sensory stimulation in utero and during birth establishes the newborn's sucking responses to maternal cues. We mimicked elements ...
Many factors have been identified to influence the risk of mother to child transmission (MTCT) of HIV. Chief amongst these is high maternal VL and advanced disease. High maternal viral load (mVL), measured at delivery, has been described as the strongest risk factor for both in utero (IU) and intrapartum (IP) transmission. Similarly, CD4+ T cell count and clinical stage of infection are also th...
Diethylstilbestrol (DES) is an estrogenic endocrine disruptor with long-term health effects, possibly including depression, following exposure in utero. Understanding the relation between in utero DES exposure and depression will provide insight to the potential adverse effects of bisphenol A, a functionally similar and ubiquitous endocrine disruptor. The association between in utero DES exposu...
Since the reports in 1956 and 1958 that in utero radiation was associated with an increased risk of leukemia and solid cancers during childhood, this issue has been debated. Many epidemiological studies have been performed. Evidence for a causal association derives almost entirely from case-control studies, whereas practically all cohort studies find no association, most notably the series of a...
BACKGROUND Child maltreatment (CM) has severe effects on psychological and physical health. The hypothalamic-pituitary-adrenal (HPA) axis, the major stress system of the body, is dysregulated after CM. The analysis of cortisol and dehydroepiandrosterone (DHEA) in scalp hair presents a new and promising methodological approach to assess chronic HPA axis activity. This study investigated the effe...
Asthma is the most common chronic disease starting in childhood and persisting into adulthood in many cases. During childhood, different forms of asthma and wheezing disorders exist that can be discriminated by the mechanisms they are caused by. Specific genetic constellations and exposure against environmental factors during early childhood and in utero play a decisive role in the early develo...
BACKGROUND In utero exposure to radiation is known to increase risks of childhood cancers, and childhood exposure is associated with increased risks of adult-onset cancers. However, little is known about whether in utero exposure to radiation increases risks of adult-onset cancers. METHODS Solid cancer incidence rates were examined among survivors of the atomic bombings of Hiroshima and Nagas...
A consideration of recent research on lead is instructive for developing research strategies in environmental toxicology. Lead research has demonstrated fruitful interactions between clinical and basic science. Thus, while epidemiological studies have suggested that central nervous system (CNS) effects in children are observed at the lowest increments of lead exposure, basic research has elucid...
