alia, cum e beta azi?

Bombi, sunt bine! Sambata dimi m-am speriat, m-am trezit cu sangerari, dar beta a fost 47,iar azi e 142.

Scientists describe mechanism that nourishes early embryo in the womb

A new study reveals how a mechanism - involving glands in the lining of the uterus - ensures the early embryo receives the nourishment it needs to grow into a healthy fetus that is big enough to receive blood from the mother.

The study shows glands in the lining of the uterus store and deliver glycogen to the placenta during early embryo growth.

The study is the work of researchers from the University of Manchester in the UK, who describe their findings in the journal Placenta.

As the single-celled fertilized egg travels along the fallopian tube, it divides repeatedly so that by the time it reaches the womb or uterus it is an embryo - a mass of over 100 cells.

The newly arrived embryo burrows into the wall of the womb - it implants itself into the lining of the uterus.

There, it grows and develops into a fetus, in tandem with the placenta, through which it will eventually receive nutrients via the mother's blood supply.

But exactly how essential glucose and other nutrients reach the early embryo as it becomes a fetus - before it is large enough to link up to the mother's blood supply - has not been clearly understood before.

This stage of development is crucial, note the researchers, and other studies have shown that poor nourishment of embryos in these early weeks can affect children's health for the rest of their lives.

For example, research of children born to Dutch women who were in their first trimester at the end of World War II when there was a food shortage shows they were more likely to develop diabetes and heart problems, compared with women whose mothers enjoyed a good diet.

Glands in the lining of the uterus store and deliver glycogen to the placenta

In their paper, the researchers describe how they found gland cells in the lining of the uterus store glucose in the form of glycogen - a form of glucose that is readily mobilized, rather like starch in plants.

The glycogen is delivered to the placenta along with glycoproteins. These are used for energy and converted into the amino acids that help form the growing embryo.

Toward the end of the first trimester, the mother's blood supply to the placenta takes over the job of nourishing the fetus and the supply from the glands in the uterus tails off.

One of the authors, John Aplin, a professor of reproductive biomedicine at Manchester, says the discovery is a "leap forward" in our understanding of how the mother delivers nutrients to the child in the womb, because:

"A newly created embryo could not survive the full force of arterial blood from the mother. Although it has been known for some time that uterine secretions nurture the tiny embryo, the mechanism whereby the nutrients leave maternal cells and are delivered to the placenta has not been understood."

The study shows that it is not only good maternal nutrition in the early weeks that matters, but also what the mother eats before conception - as this is when the nutrients are stored in the gland cells.

Prof. Aplin says we are only just beginning to understand how nutrients reach the early embryo, so it is too early to give specific advice about what mothers-to-be should be eating based on this knowledge, beyond the general advice given to women. He concludes:

"However, as the study shows, the mechanism for nutrient delivery is quite different at this stage of development and making sure that a good supply of energy is in the gland cells is an important part of ensuring a healthy embryo."

Johnny la Medlife important este sa ai o recomandare de la un dr pt a intra pe abonament. Ti-am spus ca eu am facut inclusiv pe baza unor mailuri - de la turci unde am facut FIV si de la o dr din germania specialista in imunologie reproductiva. Chiar am comentat cu tipa de la receptie pt ce anume fac analizele si mi-a urat succes.

Ba mai mult. De la Albu aveam o lista cu analize pe care mi-a dat-o cand am fost prima data la el in 2010. Ulterior a aparut chestia cu recomandarea, pe lista aceea nu era nici o semnatura sau parafa, dar era cu antetul lor. M-am dus sa repet din analize pe baza ei, sa vad daca ma puteam incumeta la inca un fiv. Nefiind parafata a trebuit sa platesc, le-am facut scris ca sunt pacienta dr A, ca am proceduri la ei, ca nu ma duc de fiecare data sa imi dea lista, ca e si asa aglomerat ... si am recuperat banii. 

Daca nu crezi ca esti suficient de convingatoare, o vizita la medicul de familie sau orice medic gineco la care ajungi usor si rugamintea sa iti puna parafa pe lista aia

Bafta !

    Hello babutze!Alia tin pumnii la o sarcina la termen,mi-a fost frica sa te mai intreb de evolutzie,dar ma bucur ca e in crestere.O zi faina dragelor

[loli1776]

Hello hello! 

Alia mă bucur , sa ai o sarcina fără probleme !

Fetelor în sfârșit am reușit sa mă programez la endocrine    Mâine dimineață mă duc , sper sa nu uit  . Acum sper sa nu mă găsească defecta și pe acolo.  

Pe urmă o sa văd ce am de făcut.  Probabil iar analize, chestii ,ca tot îmi era dor, de asta toamna nu m-am mai analizat.

Vă pup și o zi bună va doresc! 

[dea78]

Tinem pumnii pt "fara defectiuni" Loli.Eu am fentat azi o analiza,pana la urma nu a mai fost nevoie s-o fac:)))

[loli1776]

Dea Mersi pt pumnii strânși dar eu tot defecta sunt . Concluzie: un nodul iin lobul stâng,  ăla de va spuneam ca s-a marit, cu calcificari in interior și o structura modificata cu tendința la nodularizare în restul tiroidei. Acum trebuie sa repet analizele și mă mai duc peste o luna sa vedem dacă mai creste. Nu mă sfătuiește sa fac puncție ca nu are rost.
