Leydig cell tumor as a sex-cord stromal tumor is a relatively uncommon ovarian tumorin bitch. A 10-year-old female German Shepherd dog was presented because of protrusion of a large tumor-like mass of 16 × 14 × 7 cm in dimensions from her vagina. After stabilization of the patient, the mass was removed surgically and concurrent ovariohysterectomy was also performed. Macroscopically, the healthy...

Background: In mammalian ovaries, loss of over two-thirds of germ cells happens due to cell death. Nonetheless, the exact mechanism of cell death has yet to be determined. The present basic practical study was designed to detect 3 types of programmed cell death, namely apoptosis, autophagy, and necrosis, in murine embryonic gonadal ridges and neonatal ovaries.Methods: Twenty gonadal ridges and ...

primary breast lymphoma represents less than 1% of all primary breast malignancies and most primary breast lymphomas are of b-cell origin. the association of anaplastic lymphoma kinase (alk) negative anaplastic large cell lymphoma (alcl), a very rare form of primary breast lymphoma, with silicone-filled breast implants has been suggested and several case reports supported this proposal, especia...

in recent years, size of vlsi circuits is dramatically grown and layout generation of current circuits has become a dominant task in design flow. standard cell placement is an effective stage of physical design and quality of placement affects directly on the performance, power consumption and signal immunity of design. placement can be performed analytically or heuristically. analytical placer...

The tumor cells are pan-B+ and CD45+; CD5 and CD10 are positive in a minority of cases; positivity for surface Ig is found in the majority of cases, a minority of which also show intracytoplasmic Ig; some cases of the anaplastic subtype may be CD30+; usually, BCL6 is positive in cases with predominant centroblastic morphology, whereas syndecan-1 (CD138) tests positive in the immunoblastic varia...

DESCRIPTION A 52-year-old heavy smoker presented with history of abdominal pain of 2month duration. He developed cough and streaky haemoptysis for 15 days. Physical examination revealed mildly tender and enlarged nodular liver palpable upto the right iliac fossa. Contrast-enhanced CT examination of the thorax and abdomen (figure 1A) was performed which showed a right upper lobe lung mass (figur...

dendritic cells (dcs) are professional antigen presenting cells that have a potential role in the initiating of immune responses. the cell vaccination is a new strategy in treatment of infectious diseases and cancers. in this study, we have generated monocyte-derived dendritic cells of lymphoma patient's peripheral blood mononuclear cells then; these cells were used as vaccine in lymphoma patie...
