In our article, we analyzed new data on the origin of the hybrid genus ×. According to the morphological criteria × is a hybrid between s. l.

New Insights into the Genomic Structure of L.: Comparison of the Divergence of A-Genome and One C-Genome Oat Species.

We used next-generation sequencing analysis of the 3′-part of 18S rDNA, ITS1, and a 5′-part of the 5.8S rDNA region to understand genetic variation among seven diploid A-genome Avena species. We used 4−49 accessions per species that represented the As genome (A.

Primary Extranodal Marginal Zone Lymphoma of the Renal Pelvis: A Case Report and Review of the Literature.

Lymphomas account for approximately 5% of nonurothelial tumors of the urinary tract and develop in the bladder in 90% of cases. The most common lymphomas histologic type of this location is extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma). MALT lymphoma of the upper urinary tract is casuistically rare.

Analysis of prognostic factors in diffuse large B-cell lymphoma associated with rheumatic diseases.

Objective: The risk of developing diffuse large B-cell lymphoma (DLBCL) is increased in many rheumatic diseases (RDs). It is possible that RD-associated DLBCL is a distinct subset within the category of 'DLBCL', exhibiting characteristic biological features and clinical behaviour. However, information on RD-associated DLBCL is limited.

The non-leukemic T cell large granular lymphocytic leukemia variant with marked splenomegaly and neutropenia in the setting of rheumatoid arthritis - Felty syndrome and hepatosplenic T cell lymphoma mask.

T cell large granular lymphocytic (T-LGL) leukemia is a rare type of mature T cell neoplasm. The typical features of T-LGL leukemia include an increased number of large granular lymphocytes in the peripheral blood, cytopenia (most commonly neutropenia), and mild-to-moderate splenomegaly. Up to 28% of patients with T-LGL leukemia have rheumatoid arthritis (RA).
