Stem cell therapy, which has promising results in acute disorders such as stroke, supports treatment by providing rehabilitation in the chronic stage patients. In acute stroke, thrombolytic medical treatment protocols are clearly defined in neurologic emergencies, but in neurologic patients who miss the “thrombolytic treatment intervention window,”...

Objective Treatment for COVID-19 is still urgent need for the critically ill and severe cases. UC-MSC administration has a therapeutic benefit for severe COVID-19 patients even in the recovery period. In this paper, we aimed to present our clinical experience with UC-MSC treatment in severe and critical severe COVID-19 patients. Methods In this st...

Fabry disease (FD) is an X-linked lysosomal storage disorder caused by a deficiency in the enzyme α-galactosidase A due to mutations in the GLA gene. This leads to an accumulation of globotriaosylceramide (GL-3) in many tissues, which results in progressive damage to the kidneys, heart, and nervous system. We present the molecular and clinical char...

Background and objectives: The objective of this study is to determine the prevalence of factor V Leiden (G1691A), prothrombin (G20210A) and MTHFR (C677T) gene mutations in 201 Turkish patients who were referred to our clinic with venous thrombosis complications such as deep venous thrombosis, ischemic complications, thromboembolism and coronary ar...

Double balanced translocations are particularly rare and the risk of a fetus with an unbalanced chromosomal anomaly is greater than for single translocation carriers. In this present case, we describe an interesting family history which included three generations. A couple, married for 4 years, was referred to the genetic clinic due to infertility...

Preimplantation genetic diagnosis is a preventive approach for identifying genetic abnormalities in early stages of reproduction. We used preimplantation genetic aneuploidy screening in 230 cycles of patients with indications of advanced maternal age, recurrent implantation failure, recurrent spontaneous abortions, or severe male factor. Biopsied b...

Bone Marrow Transplantation is a high quality, peer-reviewed journal covering all aspects of clinical and basic haemopoietic stem cell transplantation.

Coronary Artery Disease (CAD) is the atherosclerosis of coronary arteries that carry blood to the heart muscle. Atherosclerosis is an inflammatory disease. Cytokine gene variations such as those associated with the IL1 family are involved in the pathogenesis of atherosclerosis. The purpose of this study was to determine the relationship between IL1...

The aim of this study was to evaluate the efficacy of preimplantation genetic screening (PGS) in women younger than 38 years and who had recurrent implantation failure (RIF). A prospective nonrandomized parallel group study was performed in the assisted reproduction unit of a private tertiary care hospital. 140 infertile couples who had three or mo...

Balanced chromosomal rearrangements could lead to unbalanced segregation gametes during meiosis. In this study, sperm flourescence in situ hybridization (FISH) analysis of meiotic segregation products of four reciprocal translocations; 46,XY,t(7;10)(q21;q22), 46,XY,t(15;17)(q11;p12), 46,XY,t(6;13)(p21.1;q32), and 46,XY,t(1;13)(q24;q10) are presente...

The experience on prenatal chromosome diagnosis of four Turkish centers participating in a collaborative study on 6041 genetic amniocentesis performed during a 4-8 years period were reviewed. 5887 (97.5%) patients had strong clinical indications for prenatal chromosome studies and 154 (2.5%) were referred because of maternal anxiety and a bad histo...

We report a case of a family with one sister and one brother in which the brother inherited a t(1;13)(q24;q10) translocation from his mother. We describe a case with a clear translocation between the long arm of chromosome 1 and the long arm of chromosome 13. It is possible that the APOE and MTHFR genotypes and lower folate status may also be respo...
