Structure Modification Converts the Hepatotoxic Tacrine into Novel Hepatoprotective Analogs.

The liver is responsible for critical functions such as metabolism, secretion, storage, detoxification, and the excretion of various compounds. However, there is currently no approved drug treatment for liver fibrosis. Hence, this study aimed to explore the potential hepatoprotective effects of chlorinated and nonchlorinated 4-phenyl-tetrahydroquinoline derivatives.

The genotype distribution of the XRCC1, XRCC3, and XPD DNA repair genes and their role for the development of acute myeloblastic leukemia.

Aim: To investigate if there is an association between the different DNA repair gene polymorphisms and the risk of development of acute myeloid leukemia (AML) in a sample of the Egyptian population and to find out if there is any interaction between these polymorphisms and the NQO1 gene that acts to protect the cells from oxidative damage.

Results: Our study was conducted on 90 patients with de novo AML and 60 healthy subjects with matched age and sex. We studied polymorphisms in three DNA repair genes; XRCC1, XRCC3, and XPD.

Dual color FISH on CBF primary acute myeloid leukemia.

In acute myeloid leukemia (AML), clonal chromosomal aberrations constitute markers of diagnostic value and the molecular characterization of numerous abnormalities has greatly improved the understanding of the biology of distinct subtypes of the disease. Two of the most common recurring chromosomal abnormalities in AML are t(8;21) and inversion of chromosome 16 or its variant which belong to core binding factor (CBF) AML group. We aimed to compare between cytogenetics and dual color Fluorescence In Situ Hybridization (FISH) regarding their sensitivity for detection of CBF AML associated translocations including t(8;21) and inv(16)/t(16;16).

Antibody screening in repeatedly transfused patients.

The purpose of pretransfusion compatibility testing is to prevent immune mediated hemolytic transfusion reactions. Our study aimed to evaluate the gel test for detection of clinically significant antibodies in repeatedly transfused patients. We investigated 200 thalassemic patients in whom, blood group, Rh-D, Rh phenotype determination, antibody screening and identification were done using an ID Microtyping System.

A fluorescence in situ hybridization map of 6q deletions in acute lymphocytic leukemia: identification and analysis of a candidate tumor suppressor gene.

With the objective of identifying candidate tumor suppressor genes, we used fluorescence in situ hybridization to map leukemia-related deletions of the long arm of chromosome 6 (6q). Twenty of 24 deletions overlapped to define a 4.8-Mb region of minimal deletion between markers D6S1510 and D6S1692 within chromosome 6 band q16.
