Quotes About Fetal

In reference to cases of testicular feminization]: "The incredible lesson about our sexual biology is that all men at one point in their fetal development have the capacity to be women. Moreover the body is programmed to develop as a female unless it sees and recognizes specific biochemical signals such as testosterone and anti-mullerian factor that tell it to develop as a male.

Even though I am a mathematician, I look at [fetal development] with marvel: How do these instruction sets not make mistakes as they build what is us?

genes and fetal environment are relevant. But most important, recall the logic of collapsing different types of trauma into a single category. What counts is the sheer number of times a child is bludgeoned by life and the number of protective factors.

Remarkably, the fetal brain generates far more neurons than are found in the adult. Why? During late fetal development, there is a dramatic competition in much of the brain, with winning neurons being the ones that migrate to the correct location and maximize synaptic connections to other neurons. And neurons that don't make the grade? They undergo "programmed cell death"—genes are activated that cause them to shrivel and die, their materials then recycled.

This was based on studies of a rare disorder, congenital adrenal hyperplasia (CAH). An enzyme in the adrenal glands has a mutation, and instead of making glucocorticoids, they make testosterone and other androgens, starting during fetal life.

the fetal brain generates far more neurons than are found in the adult.

tiene relación con la mayor o menor exposición a la testosterona en el útero materno.

The timing of this effect of testosterone is crucial. If it comes too late in fetal development, the key neurons in the hypothalamus are already dead, and the brain is set on an irreversible female course. Other regulators of neuronal death may also have decisive behavioral effects, but none is as obvious as testosterone.

To replace wiring diagrams, Marcus suggests a better analogy: The brain is like a book, the first draft of which is written by the genes during fetal development. No chapters are complete at birth, and some are just rough outlines waiting to be filled in during childhood. But not a single chapter—be it on sexuality, language, food preferences, or morality—consists of blank pages on which a society can inscribe any conceivable set of words.

Night took the faces of this man and woman and peeled them off like a question formed inside a fetal darkness mouth.

Advocates of unrestricted abortion do not want the public to focus on these undeniable facts of fetal development, but the facts cannot be ignored.

Starting in the womb, the developing brain begins to store parts of our life experience. Fetal brain development can be influenced by a host of factors including mother's stress; drug, alcohol, and nicotine intake; diet; and patterns of activity.

What specially excited him when his graduate student Daniel Linzer, who did the original experiments, showed him his results was that the rogue protein occurred in large quantities in the SV40-infected cells, suggesting it must be doing something important, and that it was interacting specifically with the viral oncogene, large T antigen. What's more, his team had found exactly the same protein also in uninfected fetal cells.

The earliest period at which I have been able to detect the existence of the spleen in the human embryo is at the second month.

Through their work with fetal tissue, researchers hope to find ways to harness embryonic stem cells which have the ability to become any type of human cell and could provide new treatments for many illnesses.

Abortion restrictions 'reduce pregnant women to no more than fetal containers.'

I would prefer to believe that a market in fetal organs would empower women to use their reproductive capabilities to their own economic advantage.

The earliest and most dramatic changes in maternal physiology are cardiovascular. These changes improve fetal oxygenation and nutrition.

It's understandable that when something new comes out that's unfamiliar, scary, and has severe outcomes, it gets a lot of media attention. In fact, the Zika outbreak is unprecedented. We've never before identified a mosquito-borne infection that can cause fetal malformations.

Abortions that occur late in pregnancy are often due to extreme, extenuating circumstances such as when a woman's life is in danger, when there has been a severe fetal diagnosis, or when the pregnancy is not viable.

I would prefer to believe that a market in fetal organs would empower women to use their reproductive capabilities to their own economic advantage.

The cloud of the consommé's warmth enveloped her face and revived her poise. In the liquid a slice of lemon lay at fetal peace.

estrogen is essential to the maturation and preservation of bones not only in women, as had been known, but also in men; that estrogen metabolism affects glucose metabolism and therefore the risk of diabetes; and that, contrary to dogma, estrogen is not essential to fetal survival. Fetal mice don't need it, and

estrogen is essential to the maturation and preservation of bones not only in women, as had been known, but also in men; that estrogen metabolism affects glucose metabolism and therefore the risk of diabetes; and that, contrary to dogma, estrogen is not essential to fetal survival. Fetal mice don't need it, and fetal humans don't need it.
