Developmental programming through epigenetic changes.
The last decade has seen an exponential number of scientific articles addressing the concept of fetal programming of adult onset diseases. Though it has long been known (as it is probably part of common knowledge in human history) that the environment and life events during the fetal period impact on the child’s development, the notion that intrauterine life can also impact on adult health and ...
متن کاملDevelopmental changes in NMDA neurotoxicity reflect developmental changes in subunit composition of NMDA receptors.
Excitotoxicity is generally studied in dissociated neurons, cultured hippocampal slices, or intact animals. However, the requirements of dissociated neurons or cultured slices to use prenatal or juvenile rats seriously limit the advantages of these systems, whereas the complexity of intact animals prevents detailed molecular investigations. In the present experiments, we studied developmental c...
متن کاملDevelopmental changes in achievement motivation Running head: DEVELOPMENTAL CHANGES IN PE Developmental Changes in Achievement Motivation and Affect in Physical Education: Growth Trajectories and Demographic Differences
We examined changes in student achievement goals, perceptions of motivational climate and affective responses in secondary school physical education. Greek junior high school students (N = 394; 191 males and 203 females) responded to a multi-section questionnaire twice a year from the ages of 12 -15 years. Multilevel modeling analyses showed significant linear decreases in perceptions of task-i...
متن کاملDevelopmental changes occurring in isolated intact etioplasts.
When dark-grown plants are illuminated, the characteristic morphology of the etioplast changes. The tubules of the paracrystalline prolamellar body disperse as the membranes reorganize and 'grow out' as 'perforated' thylakoids. Similar changes are expected during the greening of the isolated etioplasts of Avena. Under certain preparative conditions the morphological changes vary from those prev...
متن کاملDevelopmental changes in aural acoustic admittance measurements.
Tympanometry is a clinical measurement routinely included in the assessment of middle ear function. Despite its widespread use, however, fundamental questions remain regarding the need for age-dependent normative data. This study examines normal developmental changes associated with four tympanometric measurements: (1) ear canal volume, (2) peak compensated acoustic admittance, (3) tympanometri...
متن کاملDevelopmental changes in the fetal pig transcriptome.
Growth and development of pig fetuses is dependent on the coordinated expression of multiple genes. Between 21 and 45 days of gestation, fetuses experience increasing growth rates that can result in uterine crowding and increased mortality. We used differential display reverse transcription-PCR (DDRT-PCR) to identify differentially expressed genes in pig fetuses at 21, 35, and 45 days of gestat...
