Abstract Case report A 43-year-old woman presented with acute onset migratory right iliac fossa pain, on a background of intermittently painful groin swelling. CT demonstrated differential diagnosis appendicitis besides an ovarian cyst. Diagnostic laparoscopy was undertaken view to and treat possible appendicitis, cyst inguinal hernia. To our surprise, haemorrhagic nuchal seen intraoperatively,...

The development of the pancreas and the pancreatic islets has been an area of particular scientific interest over the last several years as our attention has turned toward the possible engineering of progenitor cells and stem cells into pancreatic β cells and pancreatic islets. Pancreatic development is a highly complex process in which two morphologically distinct tissue types must derive from...

Encystation in Phytophthora parasitica can be divided into 3 stages. In the first, the zoospores line their peripheries with flattened vesicles and nbrillar vacuoles in preparation for encystation. In the second stage, as the zoospores round up and shed their flagella, an initial wall is produced which takes the form of the mature cyst wall in thickness, but not in density. The participation of...

In metamorphosing wing discs, progression through the cell cycle takes place, as in larval discs, in nonclonally derived clusters of cells synchronized in the same cell cycle stage. Contrary to early discs, there are temporal and spatial heterogeneities in cell proliferation associated with wing margin, vein, intervein, and middle intervein territories. Within these territories, there are no in...

The c-ret gene encodes a receptor tyrosine kinase that is expressed in the Wolffian duct and ureteric bud of the developing excretory system. Newborn mice homozygous for a mutation in c-ret displayed renal agenesis or severe hypodysplasia, suggesting a critical role for this gene in metanephric kidney development. To investigate the embryological basis of these defects, we characterized the ear...

The pineal body was for a long time looked upon as a functionless remnant and from a phylogenetical point of view was accepted as a rudiment of the third eye, which is, at the present time, only found in hatteria punctata. As far as is known an epiphysis is present in all ver tebrates with the exception of mixinoids and crocodilia. In man the pineal body is pear shaped, lies just beneath the sp...
