Abstract To protect the images and provide a more secure cipher image, DNA encoding is crucial in image encryption. Applying single, easily detectable coding rule to during has no impact on encryption model's security level. Therefore, using various rules while applying dynamic DNA-coding techniques have emerged strengthen improve of its security. This study integrates method with an model. The...

The theory of respectively interpretation proposed in Yatabe and Tam (2021) "In defense an HPSG-based non-constituent coordination" (Linguistics Philosophy 44, pp. 1-77) entails that Binding Conditions A B need to be formulated as constraints on the form semantic representations. It is possible formulate two binding conditions such if anaphoric relations are encoded representations a way analog...

introduction: dna damage, as an important initiator of neuronal cell death, has been implicated in numerous neurodegenerative conditions. previously we have delineated several pathways that control embryonic cortical neuronal cell death evoked by the dna-damaging agent, camptothecin. the camptothecin, topoisomerase ι inhibitor, has been shown to induce cortical neuronal cell death in a reproduc...

Background: Impaired DNA repair mechanism is one of the main causes of tumor genesis. Study of intrinsic radiosensitivity of cancer patients in a non-target tissue (e.g. peripheral blood) might show the extent of DNA repair deficiency of cells in affected individuals and might be used a predictor of cancer predisposition. Methods: Initial radiation-induced DNA damage (ratio of Tail DNA/Head DN...

objective: the discovery and development of natural products with potent antioxidant properties has been one of the most interesting and promising approaches in the search for treatment of cns injuries. the most significant consequence of the oxidative stress is thought to be the dna modifications, which can become permanent via the formation of mutations and other types of genomic instability ...

AIM To investigate the impact of abnormal sperm morphology using the sperm deformity index (SDI) on reactive oxygen species (ROS) production and its correlation with sperm DNA damage. METHODS Semen samples were collected from men undergoing infertility screening (n = 7) and healthy donors (n = 6). Mature spermatozoa were isolated and incubated with 5 mmol/L beta-nicotinamide adenine dinucleot...

The Ddc1/Rad17/Mec3 complex and Rad24 are DNA damage checkpoint components with limited homology to replication factors PCNA and RF-C, respectively, suggesting that these factors promote checkpoint activation by "sensing" DNA damage directly. Mec1 kinase, however, phosphorylates the checkpoint protein Ddc2 in response to damage in the absence of all other known checkpoint proteins, suggesting i...

BACKGROUND Human sperm DNA damage may adversely affect reproductive outcomes, and the spermatozoa of infertile men possess substantially more DNA damage than that of fertile men. To date, there is no available treatment for men with high levels of sperm DNA damage. The objective of this study was to examine the effect of varicocelectomy on sperm DNA denaturation (DD, an index of sperm DNA damag...

The aim of this work is to present the experimental results in form an algorithm for analyzing modification screen printed electrodes, including possibility its regeneration irreversibly oxidizing biologically active compounds (drugs, DNA and proteins). A protocol was developed quantitative analysis study mechanism drug-DNA interaction by differential pulse voltammetry, following parameters: co...

The present study compares the formation of DNA adducts, determined by (32)P-postlabelling, in the livers of rats given tamoxifen and the N-demethylated metabolites N-desmethyltamoxifen and N, N-didesmethyltamoxifen. Results show that after 4 days treatment (0.11 mmol/kg i.p.), similar levels of DNA damage were seen after treatment with either tamoxifen or N-desmethyltamoxifen [109 +/- 40 (n = ...
