Ultrasonographic measurement of the yolk sac

BJOG: An International Journal of Obstetrics & Gynaecology, 1982
Summary. Ultrasonographic measurements of the yolk sac were made during first trimester in 100 pregnancies. The results were related to the crown‐rump length of the embryos and showed an increase in size from 7 to 11 weeks menstrual age. A possible relation between anomalies in yolk sac development and embryonic development was studied in six patients

Yolk Sac Tumor

1985
Yolk sac tumor (YST) or endodermal sinus tumor is the most common malignant germ cell tumor of the testis in children, and is the second most frequent malignant germ cell tumor of the ovary, being exceeded in frequency by dysgerminoma (seminoma). The incidence of malignant tumors of the testis was 1.0 cases per million U.S.

Glycans of the early human yolk sac

The Histochemical Journal, 1995
The pattern of glycan distribution in the early human yolk sac has been investigated using a panel of lectins. Two 6-week and one 8-week human yolk sacs, and one 8-week fetal liver from live, ectopic pregnancies were fixed and embedded in epoxy resin. Lectin histochemistry was carried out on sections of these tissues using 23 biotinylated lectins and ...

Pure Yolk-Sac Tumor of the Lung

Asian Cardiovascular and Thoracic Annals, 2008
Primary germ cell tumors of the chest often localize in the anterior mediastinal compartment. Such tumors originating from lungs and pleura are rare. Chest tomography revealed a mass in the middle lobe of the right lung in a 25-year-old man. A middle lobe medial segmentectomy was performed, and chemotherapy was applied postoperatively.

Transdifferentiation of mouse visceral yolk sac cells into parietal yolk sac cells in vitro

Biochemical and Biophysical Research Communications, 2016
The mouse embryonic yolk sac is an extraembryonic membrane that consists of a visceral yolk sac (VYS) and parietal yolk sac (PYS), and functions in hematopoietic-circulation in the fetal stage. The present study was undertaken to examine the normal development of both murine VYS and PYS tissues using various molecular markers, and to establish a novel ...

PARATESTICULAR YOLK SAC TUMOR IN A CHILD

Journal of Urology, 2000
A 27-month-old boy presented with a painless left testicular mass. Physical examination revealed a solid nontender mass adherent to the left testicular upper pole and left inguinal lymphadenopathy. Testicular ultrasound demonstrated a left paratesticular 3.5 cm. solid mass and a small hydrocele (fig. 1).

Post-hatch dispersal of lake sturgeon (Acipenser fulvescens, Rafinesque, 1817) yolk-sac larvae in relation to substrate in an artificial stream

, 2013
Summary Knowledge of the effects of environment and genotype on behavior during early ontogenetic stages of many fish species including lake sturgeon (Acipenser fulvescens) is generally lacking. Understanding these effects is particularly important at

On the yolk sac of the cat

Cell and Tissue Research, 1976
The ultrastructure of feline yolk sacs from 11 stages between the 14th and the 66th day is described with reference to the endoderm and the mesothelium; supplementary histochemical and cytochemical studies are included. Despite the absence of yolk, the endodermal epithelium shows a high degree of differentiation and activity, especially in the period ...
