The alternative is that, as Bartolomaeus (1995) concluded for monociliation, the deuterostome-like traits of Owenia embryogenesis--including gastrulation by invagination into a hollow blastocoel, literal deuterostomy, and formation of ciliated bands from proliferating cells--are secondarily derived characteristics that superficially resemble equivalent characteristics of true (that is, phylogenetic) deuterostomes by convergence.
3) If, after reaching its most cephalic position, the notochord retains an attachment to the pharyngeal endoderm as it regresses toward the skull base, an invagination of the developing pharyngeal mucosa is created.
Other surgical approaches such as the invagination of the diverticula, the primary closure of the perforation and omental patch and the diverticulectomy should be avoided since they present high mortality rates.
In the present case uterus was fully repositioned by inserting hand to tip of the uterine horns to be sure that no invagination is remained to elicit recurrence (Fubini and Ducharme, 2006).
Histopathologically a keratotic plug fills an epithelial invagination.
Postsynaptic invagination diameters for the three species were compared using a two-way analysis of variance (ANOVA).
5) The development of negative middle ear pressure, focal retraction of the tympanic membrane (often in an area of previous weakness), invagination of the retraction pocket, and subsequent accumulation of squamous debris have been well documented in human investigations, (2) animal experiments, (6) and temporal bone studies.
Fingers were inserted to make sure that there is no remaining invagination that could incite abdominal straining and another eversion.
Histopathology of skin biopsy taken from the raised hyperkeratotic ridge of the skin lesion, revealed column of tightly packed parakeratotic cells within a keratin-filled epidermal invagination i.
The apical organ located at the anterior end appears as a small invagination, brightly labeled with phallacidin and surrounded by four large epidermal cells (Fig.
The ectodermal side of each invagination is known as the branchial cleft.
The second, more plausible, theory is that these tumors arise from an invagination of multipotential mesothelium with subsequent mucinous metaplasia of the mesothelial lining cells, giving rise to a mucinous cyst that enlarges to form a cystic tumor The presence of the flat to low cuboidal cells, positive for calretinin, a mesothelial marker, supports this origin.
