As shown in Tables 5 and 6, noninvasive detected atrophic gastritis methods, described in this article, have quite high sensitivity at detected non-atrophic and antral severe atrophic gastritis and corpus severe atrophic gastritis, excepting mild antral atrophic gastritis and mild corpus atrophic gastritis cases.
Cattle having low number of antral follicles show reduced response to superovulation (Ireland et al 2007) and much lower circulating concentrations of progesterone and reduced endometrial thickness from day 0 to 6 of the estrous cycle (Jimenez- Krassel et al 2009) compared with cattle of similar age with a higher antral follicular count.
(C) Immunohistochemical localization of P450arom in the granulosa cell layers of the large antral follicles; e-h are enlargements of the regions marked in a-d (original magnification: a-d, 100x; e-h, 400x; bars = 80 pm in a-d and 30 pm in e-h).
The length, width, thickness, weight, and number of macroscopic ovarian structures (antral follicles, corpora lutea, corpus albicans and hemorrhagic body) of both ovaries (right and left) were not statistically different.
Ovaries were used for the isolation of preantral, early antral follicles and collection of oocytes from visible antral follicles.
To determine the Cx43 expression (percentage of positive staining out of the total follicle or tissue area), digital images of the tissues containing primary (total 33; 6-11/treatment), secondary (total 118; 19-36/treatment) and antral (total 153; 14-67/treatment) follicles were taken and analyzed using a computerized image analysis program.
During these periods a few follicles may develop to the antral stage, but they soon regress.
concluded that women with high basal FSH respond well to stimulation and produce good number of oocytes giving them an equal chance to become pregnant as compared to normal women of their age.17 Antral follicles are measured by the means of TVS.
The assessment of ovarian reserves involves a battery of variables including age, antral follicle counts (AFCs), hormonal tests including FSH, E2 and anti-mullerian hormone (AMH).
This is the first study on the construction of the relationship between a non-obstructive gastric antral web and gastric-outlet obstruction in children and adults.
Historically, the Caldwell-Luc procedure was performed to remove the antral portion of the polyp.
[2] At the same time the incidence of antral carcinoma of stomach producing GOO has comparatively increased, which may be due to increased early diagnosis of the condition with the help of flexible fiberoptic endoscope.
