Survey on Modern Cryptography

Journal of Kufa for Mathematics and Computer, 2021
Security is one of the significant difficulties that individuals are confronting when the information exchanged over the internet in today's world. Cryptography is the way to achieve security of network or data by hiding the important information from ...

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Analytical Comparison Of RSA And RSA With Chinese Remainder Theorem

JISR on Computing, 2016
RSA encryption algorithm is one of the most powerful public key encryption algorithm. The problem with RSA algorithm is that RSA decryption is relatively slow in comparison to RSA encryption.

FOUR STAGE SECURITY ALGORITHM FOR DATA TRANSFER TO IMPROVE SECURITY IN MANET

ICTACT Journal on Communication Technology, 2022
Mobile Ad hoc Network (MANET) regarded to be a group of mobile nodes that can communicate with others in the absence of network infrastructure. MANET is at high risk due to its basic features, such as peer-to-peer (P2P) architecture; wireless shared ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

A Novel and Efficient Multiple RGB Images Cipher Based on Chaotic System and Circular Shift Operations

IEEE Access, 2020
In real time scenarios, the single image encryption schemes are not that efficient when a bunch of color images is to be encrypted. This problem should be addressed due to computational cost incurred by multiple executions of single color-image ...

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.
