Two parental strains of laboratory mice, NZB and CBA/H, were chosen for their differences in attack behavior. NZB have higher scores than CBA/H. An effect of the Y chromosome on attack behavior was determined for two maternal environments. Each male was tested once in a dyadic encounter with an A/J male as a standard opponent. The two reciprocal F1s and the four reciprocal backcrosses were used...

Maternal asthma is a risk factor for development of asthma in children, but mechanisms remain unclear. Offspring of asthmatic mother mice (sensitized and repeatedly exposed to OVA Ag) showed airway hyperresponsiveness and allergic pulmonary inflammation after an intentionally suboptimal OVA sensitization and exposure protocol that had little effect on normal offspring. Similar results were obta...

Background: One of the most important indicators of quality of services and monitoring health services is evaluation and assessment of patient satisfaction of services that comes from sociology research. Aim: To identify the effect of providing post partum care at home on maternal received care and satisfaction. Method: This clinical trial was carried out on 200 mothers who referred to Akbar Ab...

The effect of second stage delivery management on maternity experience and maternal fatigue in primiparous women

BACKGROUND Young children's diets are currently suboptimal. Given that mothers have a critical influence on children' diets, they are typically a target of interventions to improve early childhood nutrition. Understanding the maternal factors which mediate an intervention's effect on young children's diets is important, but has not been well investigated. This research aimed to test whether mat...

BACKGROUND Exposure to parental smoking is associated with wheeze in early childhood, but in 2006 the US Surgeon General stated that the evidence is insufficient to infer a causal relationship between exposure and asthma in childhood and adolescents. AIMS To examine the association between maternal and paternal smoking and symptoms of asthma, eczema and rhinoconjunctivitis. METHODS Parents ...

Maternal vocal imitation of infant vocalizations is highly prevalent during face-to-face interactions of infants and their caregivers. Although maternal vocal imitation has been associated with later verbal development, its potentially reinforcing effect on infant vocalizations has not been explored experimentally. This study examined the reinforcing effect of maternal vocal imitation of infant...

The med-1 and med-2 genes encode small, highly similar proteins related to GATA-type transcription factors and have been proposed as necessary for specification of both the mesoderm and the endoderm of Caenorhabditis elegans. However, we have previously presented evidence that neither maternal nor zygotic expression of the med-1/2 genes is necessary to specify the C. elegans endoderm. Contradic...

OBJECTIVE To investigate the association of prenatal alcohol exposure with balance in10-year-old children. DESIGN Population-based prospective longitudinal study. SETTING Former Avon region of UK (Southwest England). PARTICIPANTS 6915 children from the Avon Longitudinal Study of Parents and Children who had a balance assessment at age 10 and had data on maternal alcohol consumption. OUT...

Epigenetic regulation in mammals begins in the first stages of embryogenesis. This prenatal programming determines, in part, phenotype expression in adult life. Some species, particularly dairy cattle, are conceived during the maternal lactation, which is a period of large energy and nutrient needs. Under these circumstances, embryo and fetal development compete for nutrients with the mammary g...
