chromatin-associated DNA-directed DNA polymerase activity, and the soluble RNase-sensitive endogenous DNA polymerase activity were examined in two fibroblast cell lines (WI-38 and WI-38VA13), in thirteen lymphoid cell lines originated from normal persons or from acute lymphocytic leukemia, acute myelocytic leukemia, Burkitt lymphoma, or multiple myeloma patients, and also in cells obtained dire...

lowed by determination of radioactivity in respiratory COj, protein, lipids, organic acids, and free amino acids. The greatest quantitative and qualitative changes in asparagine metabolism were found in lymphosarcoma with leukemic blood picture. Chronic lymphocytic leukemia resembled the normal pattern with acute lymphocytic leukemia occupying an intermediate position. With pro gression of chro...

Ferroptosis is a newly defined programmed cell death (PCD) process with the hallmark of accumulation iron-dependent lipid peroxidation, which more immunogenic over apoptosis. shows great potential as therapeutic target against acute kidney injury (AKI), cancers, cardiovascular diseases, neurodegenerative and hepatic diseases. Accumulating evidence has highlighted that ferroptosis plays an unneg...

The Leukemia & Lymphoma Society develops and distributes both detailed and easy-to-read booklets intended to help patients and caregivers communicate with healthcare providers about their treatment and support needs. The easy-to-read booklets initially were developed for newly diagnosed patients; however, the society has learned that all patients with cancer are likely to benefit from the infor...

The phenomenon of premature chromosome condensation (PCC) was used to compare the bone marrow proliferation characteristics of 163 patients with various forms of leukemia prior to the initiation of new therapy. The proliferative potential index (PPI, or fraction of G1 cells in late G1 phase) and the fraction of cells in S phase was determined and compared to the type of disease and the bone mar...

Nitric oxide (NO) is a molecule required for many physiological functions, produced from L-arginine by NO synthases (NOS). It is a free radical, producing many reactive intermediates that account for its bioactivity. Sustained induction of the inducible form of NOS (iNOS) in chronic inflammation may be mutagenic, through NO-mediated DNA damage or hindrance to DNA repair, and thus potentially ca...

The sialic acid content of erythrocytes from healthy individuals of different blood types and of patients with known hematological disorders has been determined. The sialic acid was completely released enzymatically with sialidase and quantitated by the thiobarbituric acid method. The sialic acid content of erythrocytes was constant irrespective of ABO blood type, or anticoagulant used; viz, 0....

background : acute lymphocytic leukemia is one of the common cancers of childhood and currently, 80 percent of these children survive more than 5 years by getting the right treatment. since long-term treatment is painful and invasive, preventing the side effects and their influence on quality of life is an important issue which introduces consideration for self-care. consequently, the present s...
