Extremely Rare Synchronous Primary Neoplasms of Meckel's Diverticulum and Colon: a Report of Three Cases.

Synchronous primary neoplasms of Meckel's diverticulum and colon malignancies are rarely reported in the literature. We present three patients with synchronous primary neoplasms of Meckel's diverticulum and colon malignancies. All tumors located in Meckel's diverticulum were incidentally found at laparotomy and the definitive diagnosis was made with microscopic examination of surgical specimens.

Evaluation of the relationship between de-novo DSA development and CXCR5+PD-1+CD8+ T cells and PD-1/PD-L1 mRNA expression in kidney transplant recipients.

Background And Aims: The relationship between the Follicular Cytotoxic T cell subgroup and expression levels of PD1/PD-L1 genes and the development of donor specific antibody (DSA) is unknown. In this study, we aimed to examine CD8+CXCR5+PD-1+ follicular cytotoxic T cell levels and expression levels of PD1/PD-L1 genes in peripheral blood lymphocytes in de-novo DSA positive and negative kidney transplant recipients (KTR).

Methods: In our study, expression of PD-1/ PD-L1 genes by Real-Time Quantitative PCR method and CD8+CXCR5+PD-1+ T cell expression levels by flow cytometric method were obtained from peripheral blood samples.

Relationship of HLA-B alleles on susceptibility to and protection from HIV infection in Turkish population.

Objective: Many human leukocyte antigen (HLA)-B alleles are associated with an increased risk of Acquired Immune Deficiency Syndrome (AIDS) and Human Immunodeficiency Virus (HIV) progression; however, their distribution varies among different racial/ethnic groups. Abacavir used in the treatment of AIDS significantly increases the risk of hypersensitivity reactions in patients with HLA-B*57:01. The aim of this study was to determine the distribution of HIV-associated HLA-B subgroups (high and low resolution) and HLA-B*57:01 associated with Abacavir sensitivity in Turkiye.
