In the present study, we investigated the ability of the tetrapeptide NAc-Ser-Asp-Lys-Pro-OH (AcSDKP), a reported inhibitor of primitive hematopoietic cells, to influence the proliferative behavior of primitive normal and chronic myeloid leukemia (CML) progenitor cells in the adherent layer of long-term cultures (LTCs). Addition of > or = 50 ng/mL of AcSDKP to LTCs of normal cells at the time o...

Peripheral primitive neuroectodermal tumor (pPNET) is a highly aggressive small round cell tumor belonging to PNET/Ewing sarcoma family. Ovarian tumors composed of primitive neuroectodermal elements are extremely rare. Herein we reported two cases of peripheral primitive neuroectodermal tumors of ovary in two patients with different clinical presentations. Definite diagnoses were made bas...

The need for a suitable classification of media types arises for several reasons when building or comparing multimedia systems. Within an Intelligent Multimedia Presentation Systems (IMMPS) it is necessary to formulate and encode design knowledge for decision making on the appropriate medium in which to present information and for the generation of the presentation. It is also required in order...

primitive neuroectodermal tumors of the kidney are rare tumors representing about 1% of all sarcomas. extraskeletal primitive neuroectodermal tumors may be found in the genitourinary tract, the testes, ovaries, uterus, or pancreas. renal primitive neuroec- todermal tumors are frequently aggressive and almost 30% of all newly diagnosed cases present with distant metastases. surgical intervention...

We consider a multilayer generalization of Ripa’s inhomogeneous-density single-layer primitive-equation model. In addition to vary arbitrarily in horizontal position and time, the horizontal velocity and buoyancy fields are allowed to vary linearly with depth within each layer of the model. Preliminary results on linear waves and baroclinic instability suggest that a configuration involving a f...

We consider a multilayer generalization of Ripa’s inhomogeneous single-layer primitive equations model. In addition to vary arbitrarily in horizontal position and time, the horizontal velocity and buoyancy fields are allowed to vary linearly with depth within each layer of the model. Preliminary results on linear waves and baroclinic instability suggest that a configuration involving a few laye...

During mouse embryogenesis the first hematopoietic and endothelial cells form in blood islands located between layers of visceral endoderm and mesoderm in the yolk sac. The role of visceral endoderm in primitive hematopoiesis and vasculogenesis is not well understood. We have assessed the consequences of a lack of visceral endoderm on blood cell and vessel formation using embryoid bodies derive...

primitive  neuroectodermal  tumor  (pnet)  of  kidney  is  an  extremely  rare  renal  neoplasm  with only about fifty reported cases in literature.  presumably,of neural crest origin, these tumors behave  aggressively  and  carry  a  poor prognosis.  we  report  a  case  of  22-year  old  female  patient complaining of left loin pain with recurrent hematuria for last 3 months. on clinical exam...

In this paper, the requirements of the graphic editor in the electrical automation monitoring system are analyzed in detail. The electrical automation monitoring system requirements, and puts forward the key technology of software architecture based on. Net platform and MVC design pattern to design and develop the technical scheme and the graphics editor, and to the local refresh, editor of gra...
