Cajal-Retzius (CR) cells, the predominant source of reelin in developing neocortex, are thought to be essential for the inside out formation of neocortical layers. Fate mapping revealed that a large population of neocortical CR cells arises from the cortical hem. To investigate the function of CR cells, we therefore genetically ablated the hem. Neocortical CR cells were distributed beneath the ...

it is very important to study and simulate s-wave structure for near surface (alluvium parts, in particular) owing to its direct relationship to urban facilities in geotechnical and earthquake engineering studies. so, in seismic microzonation, the first step is to study and identify s-wave pattern in alluvium in order to categorize different parts of cites according to s-wave velocity. current ...

Laparoscopic cholecystectomy (LC) and common bile duct exploration (LCBDE) have become the standard surgical procedure for cholecystolithiasis and choledocholithiasis. During the operation, cystic duct and vessels are usually controlled by Hem-o-Lok clips. We report a case with a complaint of severe abdominal pain for the previous 20 days. Her medical history was unremarkable except for laparos...
