  • Our collaboration allowed us to determine that the nutritional environment impacts the fetal brain at both the cellular and molecular levels," said SFBR's Laura Cox, Ph.D. "That is, we found dysregulation of hundreds of genes, many of which are known to be key regulators in cell growth and development, indicating that nutrition plays a major role during fetal development by regulating the basic cellular machinery.

  • Low birth weight, higher risk of sudden infant death syndrome (SIDS), and a myriad of other health problems can arise in babies who experience secondhand smoke during fetal development. (wisegeek.com)
  • Women who have already given birth have more relaxed uterine muscles that are consequently more sensitive to fetal motion, and for them fetal motion can sometimes be felt as early as 14 weeks. (wikipedia.org)
  • Fetal malformations and birth injuries may occur as a result of exposure to environmental toxins such as mercury or lead. (wikipedia.org)
  • movements
  • At this point in development, uncontrolled movements and twitches occur as muscles, the brain, and pathways begin to develop. (wikipedia.org)
  • Generally speaking, fetal motility can be classified as either elicited or spontaneous, and spontaneous movements may be triggered by either the spine or the brain. (wikipedia.org)
  • In addition to sideward bendings of the head, complex and generalized movements occur at the beginning of the fetal stage, with movements and startles that involve the whole body. (wikipedia.org)
  • typically
  • Communicating with your little one can help you bond, but expect more of a reaction later in the evening, when fetal activity typically increases. (surebaby.com)
  • The paper suggests the origin and underlying cause of TDS can be detected as early as in fetal life, where environmental and genomic factors could affect the development of the male reproductive system Hypospadias presents as an abnormal location for the end of the urethra which is typically found on the distal end of the penis. (wikipedia.org)
  • alcohol
  • If a child has fetal alcohol syndrome, he or she experiences problems such as mental retardation, inhibited growth, as well as a myriad of other physical and mental defects. (wisegeek.com)
  • degrees
  • Sub-par fetal conditions often cause various degrees of developmental delays, both physical and mental, for the growing baby. (wikipedia.org)
  • relatively
  • An L-S ratio of 2.4 or more indicates fetal lung maturity and a relatively low risk of infant respiratory distress syndrome, and an L/S ratio of less than 1.5 is associated with a high risk of infant respiratory distress syndrome. (wikipedia.org)
  • brain
  • Rho proteins play critical roles in neuronal migration and brain morphogenesis at early stages of brain development. (ucsd.edu)
  • Methylmercury, a worldwide contaminant of seafood and freshwater fish, is known to produce adverse nervous system effects, especially during brain development. (wikipedia.org)
  • Play media The parts of the fetal brain that control movement will not fully form until late in the second trimester, and the first part of the third trimester. (wikipedia.org)
  • Brain damage may be caused by a number of factors, including fetal malformation due to genetic mutation or exposure to toxins, intrauterine hypoxia, or physical trauma during delivery. (wikipedia.org)
  • Microcephalin (MCPH1) is a gene that is expressed during fetal brain development. (wikipedia.org)
  • Hence it has been assumed that variants have a role in brain development, but in normal individuals no effect on mental ability or behavior has yet been demonstrated in either this or another similarly studied microcephaly gene, ASPM. (wikipedia.org)
  • Microcephalin proteins contain the following three domains: N-terminal BRCT domain Central microcephalin protein domain (InterPro: IPR022047) C-terminal BRCT domain MCPH1 is expressed in the fetal brain, in the developing forebrain, and on the walls of the lateral ventricles. (wikipedia.org)

  • stage
  • Your baby has reached an important stage of development, for now there's a chance (albeit a small chance) that she could survive outside the womb if you were to deliver prematurely. (surebaby.com)
  • In humans, the fetal stage commences at the beginning of the ninth week. (wikipedia.org)
  • Locomotor activity begins during the late embryological stage, and changes in nature throughout development. (wikipedia.org)
  • Even before the fetal stage begins, a six-week-old human embryo can arch its back and neck. (wikipedia.org)
  • fetuses
  • Fetuses aged 14 to 18 weeks show a pronounced circadian rhythm in their activity level, which can be detected both by fetal electrocardiogram and by measuring locomotor activity. (wikipedia.org)
  • found
  • MUC-4 has been found to play various roles in the progression of cancer, particularly due to its signaling and anti-adhesive properties which contribute to tumor development and metastasis. (wikipedia.org)
  • blastocyst
  • Through the processes of compaction, cell division, and blastulation, the conceptus takes the form of the blastocyst by the fifth day of development, just as it approaches the site of implantation. (wikipedia.org)
  • activity
  • Between your expanding abdomen and frequent spurts of fetal activity, you'll have a hard time focusing on anything other than the life inside of you, but try not to get too anxious about what lies ahead. (surebaby.com)
