متن کاملDefining the Transcriptional Landscape during Cytomegalovirus Latency with Single-Cell RNA Sequencing
Primary infection with human cytomegalovirus (HCMV) results in a lifelong infection due to its ability to establish latent infection, with one characterized viral reservoir being hematopoietic cells. Although reactivation from latency causes serious disease in immunocompromised individuals, our molecular understanding of latency is limited. Here, we delineate viral gene expression during natura...

Ovarian cancer is a major clinical challenge in obstetrics and gynecology. The reason of this is the lack of specific symptoms for ovarian cancer before the recurrence and progression of the tumor, so many cases are not...
متن کاملSquamous Cell Differentiation in Metastatic Papillary Thyroid Carcinoma: Metaplastic
Squamous cell differentiation (SCD) may occur in papillary thyroid carcinoma (PTC) only at metastatic sites. We have studied cytokeratin CK5/6 and P63 along with TTF1 (thyroid transcription factor 1) and B-Raf (V-Raf murine sarcoma viral oncogene homolog B1) immunohistochemical expression in neck lymph node metastases of thyroid PTC showing SCD. The patient (21-years) presented wit...
متن کاملMetastatic Renal cell Carcinoma Presenting as a clear-cell Tumor in Tongue: A Case Report

The most common primary sources of metastatic tumors in the oral region are, from the most to the least common, the breast, lung, kidney, bone, and colon. Renal cell carcinoma accounts for nearly 3% of all adult malignancies. It usually metastasizes to the lungs,...
