More specifically, it comprises preparation of a specific endometrial receptivity expression microarray ERA or Endometrial Receptivity Array permitting evaluation of the receptive state of a human endometrium, together with assessment of the state of the endometrium having diagnostic and therapeutic objectives. More specifically, it involves the preparation of a microarray specific expression of endometrial receptivity ERA or Endometrial Receptivity Array to assess the receptive state of a human endometrium and to assess status of endometrium for diagnostic and therapeutic purposes. State of the art The endometrium is the mucosa lining the inside of the uterine cavity. Its function is to accommodate the embryo, allowing its implementation and promoting the development of Ia placenta. This process requires a receptive endometrium able to respond to signals blastocyst is the stage of development in which the embryo is implanted when. Human endometrium is a regulated hormonally tissue cyclically hormones Io prepared to achieve this state of receptivity are estradiol induces the cell and Ia progesterone proliferation is involved in the differentiation, causing a large number of profile changes endometrial gene expression reaching a receptive phenotype for a short period of time called “implantation window”. Although there is no complete agreement on the period of implantation in humans, clinical studies suggest that this process takes place between 20 and 24 normal ovulatory cycle Wilcox et al. The evolution of our understanding of human endometrium Ia contrasts with lack of progress in the development of new diagnostic methods for dating and study. At the present time, shows the assessment of the endometrium is still performed by histological studies based on observations described over 50 years ago Noyes et al.

La diminuzione del pH favorisce la proliferazione dei batteri gram-negativi Due possibili quadri di patologia orale possono essere identificati nella donna in gravidanza: In particolare Prevotella intermedia ha un notevole incremento nelle donne in gravidanza Diversi studi hanno dimostrato le funzioni immunosoppressive degli ormoni durante la gravidanza. Ha generalmente una forma rotondeggiante raggiungendo anche il volume di una ciliegia. Per quanto riguarda la sua istogenesi si ritiene che il mesenchima del legamento alveolo-dentale sia il punto di partenza.
Histological dating of timed endometrial biopsy tissue is not related to fertility status. Receiver operating characteristic curve for endometrial dating for all biopsies (black line), biopsies obtained in the midluteal The effect of interobserver variation in dating endometrial histology on the diagnosis of .
To examine the relationship between endometrial histological maturation and reproductive hormones, we studied 11 fertile women, aged 18—37 yr. All participants had had at least 1 previous pregnancy and cycled regularly, every 25—35 days. Women collected daily, first morning voided urine for measurement of estradiol and progesterone metabolite excretion, estrone conjugates E1c , and pregnanediol glucuronide Pdg , respectively, throughout the cycle of study.
Hormones were normalized for creatinine. Between 7—9 days after home detection of a LH surge Sure Step , participants underwent an endometrial biopsy using a small bore Pipelle catheter. Tissue was prepared for histological and biochemical analyses.

My medical students Especially if you’re looking for information on a disease with a name that you know, here are a couple of great places for you to go right now and use Medline, which will allow you to find every relevant current scientific publication. You owe it to yourself to learn to use this invaluable internet resource. Not only will you find some information immediately, but you’ll have references to journal articles that you can obtain by interlibrary loan, plus the names of the world’s foremost experts and their institutions.
Take your questions here first. Medline lists other sites that may work well for you Alternative complementary medicine has made real progress since my generally-unfavorable review. If you are interested in complementary medicine, then I would urge you to visit my new Alternative Medicine page. If you are looking for something on complementary medicine, please go first to the American Association of Naturopathic Physicians.
And for your enjoyment I cannot examine every claim that my correspondents share with me. Sometimes the independent thinkers prove to be correct, and paradigms shift as a result. You also know that extraordinary claims require extraordinary evidence. When a discovery proves to square with the observable world, scientists make reputations by confirming it, and corporations are soon making profits from it.

The utility of histological dating of endometrium in the evaluation of infertile couples is uncertain. Design Prospective multicenter study, with subjects randomly assigned to biopsy timing. Criterion standard for infertility was 12 months of unprotected, regular intercourse without conception and for fertility at least one live birth within 2 years. Setting University-based infertility practices. Patient s Volunteer subjects recruited at 12 clinical sites participating in the National Institutes of Health-funded Reproductive Medicine Network.
Inclusion criteria included ages 20—39 years, regular menstrual cycles, and no hormonal treatment or contraceptive use for 1 month before the study.

Investigation and management of an ovarian mass
Free cells of the connective tissue Fig. More info Vascular mechanisms basic to menstruation The mechanisms that regulate the menstruation phase 1rst-4th day result from the reduction in the estrogen and progesterone values, leading to a constriction of spiral arteries and consequent necrosis of the tissue. Only the functional layer of the endometrium is affected by these cyclic changes – the basal layer remains intact.
The uterine vessel network scheme exhibits a selective sensibility with regard to the cyclic hormonal alterations. The radial and basal arterioles do not react to the hormonal variations, whereas the spiral arteries of the functional layer are hormone sensitive and constrict when the progesterone concentration decreases.
Together with blood, which does not coagulate due to a local fibrinolytic factor, the necrotic tissue is eliminated menstruation.
The histology is consistent with endometrial polyp. The most common cytologic abnormality associated with endometrial polyps are aberrations of chromosome 6p Aberrations of chromosome 1p, 9q34 and loss of 7q are associated with uterine leiomyoma.
Proliferative Phase Proliferative phase change. The glands are simple appearing as circles in cross-section. Mitotic activity is conspicuous. In the endometrium, proliferative activity occurs even before the complete cessation of menstruation, i. The glands at this earlier stage are relatively straight or, at most, slightly coiled and are found within relatively loose endometrial stroma.
As the name suggests, there is brisk cell division with prominent mitotic activity in both the glands and the stroma. Under the influence of oestrogen, the stroma is often the thickest at day After this, the rate of glandular growth relative to the stroma results in coiling of the glands as the cycle moves towards ovulation. The nuclei rather than centrally-located are pseudostratified, though they tend to be found in the basal half.
Interval Phase The interval phase occurs over a short period of hours.
