A sequence environment modulates the impact of methylation on the torsional rigidity of DNA
Chemical Communications, 2018 We explain, with atomic-level detail, how DNA methylation may contribute to the regulation of biological processes. We show that DNA sequence environment modulates the impact of methylation on the physical properties of the double helix.

The Impact of Testicular Torsion on Testicular Function [PDF]
The World Journal of Men's Health, 2020 Torsion of the spermatic cord is a urological emergency that must be treated with acute surgery. Possible long-term effects of torsion on testicular function are controversial. This review aims to address the impact of testicular torsion (TT) on the endocrine- and exocrine-function of the testis, including possible negative effects of torsion on the ...

Journal of Marine Science and Engineering, 2023 Cargo ships with wide hatches usually have thin walls and limited torsional rigidity. Consequently, conducting a comprehensive torsional analysis is important because these loads can exert a significant impact. In this paper, the structural response of a
