Detection of Chlamydia trachomatis inside spermatozoa using flow cytometry: Effects of antibiotic treatment (before and after) on sperm count parameters.

There is increasing evidence that Chlamydia trachomatis (CT) infection can directly affect male fertility. However, only few have investigated the effects of CT on semen parameters, and mostly with inconclusive results. The main aims of this study were to identify CT inside spermatozoa, and the possible pre and post antibiotic treatment effects on the overall semen parameters.

Differential Expression of microRNAs in Acute and Chronic Heart Failure.

Background: MicroRNAs modify protein expression at the post-transcriptional level, and their circulating levels may help identify the underlying molecular pathways.

Objective: The purpose of this study was to assess the differential expression of microRNAs related to myocardial cell energy substrate, autophagy, and ischaemia in chronic and acute heart failure (HF).

Methods: In this case-control study, we studied 19 patients with acute HF (AHF) and 19 patients with chronic HF (CHF).

Distribution of MICA alleles and haplotypes associated with HLA-B in Greek population.

Introduction: The Major Histocompatibility Complex Class I-related chain A gene (MICA) is a highly polymorphic functional gene located close to the HLA-B locus. Certain MICA alleles have been related to inflammatory and autoimmune diseases while MICA antibodies have been implicated in organ allograft rejection or graft-versus-host disease (GVHD).

Aim: The aim of this study was to identify the frequencies of MICA alleles and MICA ~ HLA-B haplotypes in the Greek population since, as far as we know, these data are still limited.

Co-existence of Follicular Lymphoma in the Lymph Node with High-grade B Cell Lymphoma in the Bone Marrow of a Patient with Spontaneous Tumor Lysis Syndrome.

A significant percentage of B-cell lymphomas are characterized by bone marrow involvement (BMI) at diagnosis. In most cases, there is a concordance between the type of lymphoma present in the lymph node and the lymphoma present in the bone marrow. Herein, we presented a sixty-seven years old female patient, who was diagnosed with High-Grade B-cell Lymphoma (HGBL) in the bone marrow, while simultaneously, in the peripheral lymph node, the presence of Follicular Lymphoma (FL) was noted.
