Asthma is a hereditary disease associated with IgE-mediated reaction. Whether maternal atopy and paternal atopy have different impacts on perinatal IgE production and asthma development remains unclear. This paper reviews and summarizes the effects of maternal and paternal atopy on the developmental aspects of IgE production and asthma. Maternal atopy affects both pre- and postnatal IgE product...
The timing of reproductive development and associated trade-offs in quantity versus quality of offspring produced across the life span are well documented in a wide range of species. The relation of these aspects of maternal life history to monogamy and paternal investment in offspring is not well studied in mammals, due in part to the rarity of the latter. By using five large, captive-bred pop...
Paternal DNA demethylation in mammalian zygotes is achieved through Tet3-mediated iterative oxidation of 5-methylcytosine (5mC) coupled with replication-dependent dilution. Tet3-mediated paternal DNA demethylation is believed to play important roles in mouse development given that Tet3 heterozygous embryos derived from Tet3-deficient oocytes exhibit embryonic sublethality. Here, we demonstrate ...
In an observational study of 31,257 children we investigated the effects of paternal age at the time of the child's birth, paternal absence and non-biological fathers on children's health. Results are per 5 year change in paternal age. Older fathers were associated with lower rates of unintentional injuries, odds ratio (OR)=0.966, P=0.0027. There was a quadratic association between paternal age...
The transmission profiles of sperm mtDNA introduced into fertilized eggs were examined in detail in F1 hybrids of mouse interspecific crosses by addressing three aspects. The first is whether the leaked paternal mtDNA in fertilized eggs produced by interspecific crosses was distributed stably to all tissues after the eggs' development to adults. The second is whether the leaked paternal mtDNA w...
Introduction. Despite the fact that maternal perinatal mental health problems have been extensively studied and addressed to be a significant health problem, the literature on paternal perinatal mental health problems is relatively scarce. The present study aims at determining the prevalence of paternal perinatal depression and identifying the risk factors and the relationship between antenatal...
The children of older fathers have increased risks of developing schizophrenia spectrum disorders, and among those who develop these disorders, those with older fathers present with more severe clinical symptoms. However, the influence of advanced paternal age on other important domains related to schizophrenia, such as quantitative endophenotype deficit levels, remains unknown. This study inve...
OBJECTIVE To investigate the association of paternal age at conception with the risk of offspring developing schizophrenia. DESIGN A population based cohort study. SETTING Sweden. SUBJECTS 754,330 people born in Sweden between 1973 and 1980 and still alive and resident in Sweden at age 16 years. MAIN OUTCOME MEASURES Hospital admission with schizophrenia or non-schizophrenic, non-affect...
BACKGROUND Unintentional injury is the leading cause of death in young children. A previous study reported the protective effect of maternal parenting on young childhood injury; however, few studies have shown an association between paternal involvement in childcare and young childhood injury. The purpose of this study is to investigate the impact of paternal involvement in childcare to reduce ...
