| Nephroblastoma is an embryonal neoplasm derived from nephrogenic blastemal cells primarily occurring in children who are younger than 6 years. |
|
| The urachus is a remnant of allantoic origin, connecting the embryonal cloaca to the allantois during early intrauterine life. |
|
| It usually indicates the presence of a teratocarcinoma, an endodermal sinus tumour or an embryonal carcinoma. |
|
| The interplay between this information and a person's cellular machinery supplies a genetic programme controlling embryonal development, the processes of life and, possibly, death. |
|
| The 1992 Louis-Jeantet Prize for Medicine is attributed to three researchers who made significant contributions to our knowledge of cell proliferation, of embryonal development and of the immune system. |
|
| The embryonic stem cell is an almost mythically powerful and versatile human cell, fleetingly present during the earliest days of embryonal development. |
|
| It is similarly important to distinguish seminoma from yolk sac tumors because yolk sac tumors, like embryonal carcinoma, are radioresistant. |
|
| The previous pathology report identified the mass as a embryonal rhabdomyosarcoma. |
|
| A protective product will not be available for some years yet, but the most recent research shows how the embryonal brain may be protected against alcohol. |
|
| At the tested dose levels there was maximal pharmacological effectiveness of the murine analogue and high embryonal exposure to the murine analogue of tocilizumab. |
|
| The differential diagnosis that should be considered in such a case include seminoma and embryonal carcinoma. |
|
| Foci of seminoma, germinoma, choriocarcinoma, and embryonal carcinoma are not present. |
|
| A biopsy at Birmingham Children's Hospital revealed a tumour, known as embryonal rhabdomyosarcoma, of which there are only a few cases each year throughout the world. |
|
| Negative staining for CD30, TTF-1 and CEA excluded the possibility of embryonal carcinoma and negative TTF-1 staining made a lung or thyroid primary site less likely. |
|
| Rhabdomyosarcoma, the most common primary malignant orbital tumor of childhood, has been classified histologically as embryonal, differentiated, or alveolar. |
|
| Embryonal rhabdomyosarcomas are the most common soft tissue sarcomas in children. |
