We describe the clinical and laboratory findings of 78 adult patients with T-prolymphocytic leukemia (T-PLL) studied over the last 12 years. The main disease features were splenomegaly (73%), lymphadenopathy (53%), hepatomegaly (40%), skin lesions (27%), and a high leukocyte count (greater than 100 x 10(9)/L in 75%) with nucleolated prolymphocytes. A variant form with small, less typical cells ...

empirical evidence seems to indicate that economic growth has varied inversely with natural resource abundance across countries, in which high natural resources dependent economies experience the low economic growth. this paper first reviews the literature of resources curse and shows that the most important challenges of economic development of iran are those mechanisms that change the blessin...

The t(11;14)(q13;q32) translocation is considered to be the cytogenetic hallmark of mantle cell lymphoma. This report describes a case of leukaemic mantle cell lymphoma in which conventional cytogenetics on stimulated peripheral blood cells showed a 46,XY, t(1;12)(p21;q23)/46,XY karyotype. Fluorescence in situ hybridisation analysis using a dual colour immunoglobulin heavy chain (IgH)/CCND1 pro...

It first came to prominence... as a candidate gene near the chromosomal translocation t(1;14)(p22;q32) found in B-cell lymphomas of the mucosa associated lymphoid tissue (MALT). At the same time, Bcl10 was found by database searches for novel proteins with a caspase recruitment domain (CARD). Bcl stands for B cell lymphoma or leukemia, and is used for genes found through chromosomal translocati...

A new member of the proprotein convertase gene family (LPC) has been identified at a chromosome translocation breakpoint occurring in a high grade lymphoma. The translocation t(11;14)(q23;q32) has been molecularly cloned and shown to be the result of a fusion between an intron in the 3' -untranslated region of LPC with a sequence close to the switch region S gamma 4 of the IGH locus. The LPC ge...

We report a 59-year-old man with intravascular large B-cell lymphoma (IVLBCL) associated with hemophagocytic syndrome, disseminated intravascular coagulopathy, and lung involvement. G-banding analysis of the metaphase spreads obtained from the bone marrow showed that the lymphoma cells were near-tetraploid and included two homologues of the 14q+ chromosome. Spectral karyotyping revealed that co...

Chromosomal translocations involving the immunoglobulin heavy chain (IGH) locus at chromosome 14q32 represent a common mechanism of oncogene activation in lymphoid malignancies. In multiple myeloma (MM), variable chromosome partners have been identified by conventional cytogenetics, including the 11q13, 8q24, 18q21, and 6p21 loci. We and others have recently reported a novel, karyotypically und...

Aims: To describe the clinical features and genetic findings in two families presenting with microcoria inherited as an autosomal dominant trait. Methods: Both affected and unaffected members of two families displaying familial microcoria were examined. Flash photography or infrared pupillography were used to assess pupils, and a full ophthalmic examination including visual acuity and field tes...
