The second (functional) aspect of this problem eoneems the development of pathologic symptoms, the moleeular causes of which are not due to AChE inhibition. One of the first cases of OP nonanticholinesterase effeets (when the association between the OP molecular target and the functional disturbance has been proved) involved inhibition of kinurenin formamidase of the hen egg yolk sac membrane responsible for teratogenic effects (Seifert and Casida, 1978). Another example of OP teratogenic effect is abnormal development of the conjunctival tissue of Xen-opus embryos due to inhibition of lysyloxidase and incomplete post-translational modification of collagen (Snawder and Chambers, 1993). [Pg.77]

Remove the yolk sac and all membranes with fine forceps. [Pg.427]

Evaluate the yolk sac, the ectoplacental cone, and the chorionic-allantoic membrane, and their morphological integrity. [Pg.428]

The integrity of the ectoplacental cone and chorionic-allantoic membrane are considered when assigning the yolk sac score. The ectoplacental cone should be attached to the base of the... [Pg.428]

In humanS/ P-gp is expressed on trophoblastic cells throughout pregnancy (82/ 84-86). It has been located on apical surfaces of endodermal cells of the mouse yolk sac (87)/ in the vesicles of the brush border membrane of the human syncytiotrophoblast that directly faces maternal blood/ but not within maternal vascular endothelium (83/ 84/ 86-95). Actively transporting molecules in a basolateral-to-apical direction/ the role of P-gp within the placenta is similar to its function at other sites it extrudes drugs from the placenta back into maternal circulation/ thereby protecting the developing fetus from potential toxic factors within the maternal circulation (95). [Pg.348]

PLAP, placental alkaline phosphatase CDl 1 7 (c-kit), membrane staining CK, cytokeratin, rare dysgerminomas showweak staining, with AEl /AE3 embryonal carcinoma shows membrane staining and yolk sac tumor cytoplasmic staining LCA, leukocyte common antigen MPO, myeloperoxidase. [Pg.737]

FIGURE 18.44 Embryonal carcinoma. An immunostain for CD30 shows strong membrane staining, characteristic of embryonal carcinoma. Staining for cytokeratin AE1/AE3 shows a similar membrane pattern in embryonal carcinoma, as compared to a cytoplasmic pattern of staining in yolk sac tumor (see Figure 18.43). [Pg.738]
