MULTIPLE PRIMARY EXTRAMEDULLARY PLASMACYTOMAS: AN UNUSUAL PRESENTATION
Extramedullary plasmacytoma (EMP) is a rare neoplasm of soft tissue which usually arises in the respiratory tract, nasal cavity, sinuses and nasopharynx. Multiple extramedullary plasmacytomas are extremely rare, especially those that are not associated with multiple myeloma.We describe multiple primary EMP in a 37 year old man, without involvement of bone or bone marrow. EMP usually has a ...
متن کاملPhosphorothioation: An Unusual Post-Replicative Modification on the DNA Backbone
DNA molecules are polymers composed of basic repeating subunits of deoxyribonucleotides, which consist of the deoxyribose sugar, phosphate groups, and a nitrogenous base. They appear to fulfill all requirements necessary to maintain the genetic function of DNA. The five elements of nitrogen, phosphorus, carbon, hydrogen, and oxygen had been regarded as the canonical composition of DNA until the...
متن کاملNuclear-encoded factors involved in post-transcriptional processing and modification of mitochondrial tRNAs in human disease
The human mitochondrial genome (mtDNA) encodes 22 tRNAs (mt-tRNAs) that are necessary for the intraorganellar translation of the 13 mtDNA-encoded subunits of the mitochondrial respiratory chain complexes. Maturation of mt-tRNAs involves 5' and 3' nucleolytic excision from precursor RNAs, as well as extensive post-transcriptional modifications. Recent data suggest that over 7% of all mt-tRNA res...
متن کاملComplete sequence of the mitochondrial genome of Tetrahymena pyriformis and comparison with Paramecium aurelia mitochondrial DNA.
We report the complete nucleotide sequence of the Tetrahymena pyriformis mitochondrial genome and a comparison of its gene content and organization with that of Paramecium aurelia mtDNA. T. pyriformis mtDNA is a linear molecule of 47,172 bp (78.7 % A+T) excluding telomeric sequences (identical tandem repeats of 31 bp at each end of the genome). In addition to genes encoding the previously descr...
متن کاملPrimary Fallopian Tube Cancer: An Unusual Case of Inguinal Lymphadenopathy
Background: Primary fallopian tube cancers (PFTCs) are rare gynecological malignancies by the prevalence of 0.3-1%. The PFTCs occur in individuals within the age range of 18-88 years, more specifically at the age range of 40-65 years with the mean age of 55 years. The PFTC usually is observed with the chronic inflammation of the fallopian tube, infertility, tuberculous salpingi...
