Mechanical Mechanisms of Chromosome Segregation [PDF]

open access: yesCells, 2021
Chromosome segregation—the partitioning of genetic material into two daughter cells—is one of the most crucial processes in cell division. In all Eukaryotes, chromosome segregation is driven by the spindle, a microtubule-based, self-organizing subcellular structure.

Imprinting Mechanisms [PDF]

open access: yesGenome Research, 1998
A number of recent studies have provided new insights into mechanisms that regulate genomic imprinting in the mammalian genome. Regions of allele-specific differential methylation (DMRs) are present in all imprinted genes examined. Differential methylation is erased in germ cells at an early stage of their development, and germ-line-specific ...

Ribosome Mechanics Informs about Mechanism [PDF]

open access: yesJournal of Molecular Biology, 2016
The essential aspects of the ribosome's mechanism can be extracted from coarse-grained simulations, including the ratchet motion, the movement together of critical bases at the decoding center, and movements of the peptide tunnel lining that assist in the expulsion of the synthesized peptide. Because of its large size, coarse graining helps to simplify

Life’s Mechanism

open access: yesLife, 2023
The multifarious internal workings of organisms are difficult to reconcile with a single feature defining a state of ‘being alive’. Indeed, definitions of life rely on emergent properties (growth, capacity to evolve, agency) only symptomatic of intrinsic functioning. Empirical studies demonstrate that biomolecules including ratcheting/rotating enzymes,

Mechanical Thrombectomy

open access: yesAnnals of Indian Academy of Neurology, 2022
Large vessel occlusion stroke contributes to disability and mortality out of proportion to its incidence. Over time it was noted that intravenous thrombolysis alone was not sufficient for this stroke type. Slowly, endovascular approach and mechanical clot retrieval have come out to be the biggest advances in the field of ...

Physical and combustible properties of briquettes produced from a combination of groundnut shell, rice husk, sawdust and wastepaper using starch as a binder

open access: yesJournal of Applied Sciences and Environmental Management, 2020
This study investigated the use of agro-wastes for the production of briquettes. Briquettes were produced from a combination of groundnut shell, rice husk, sawdust and wastepaper using the 20:70:10, 30:60:10, 40:50:10, 50:40:10, 60:30:10 and 70:20:10 ...

Tendon mechanobiology in small-animal experiments during post-transection healing [PDF]

open access: yesEuropean Cells & Materials, 2021
Ruptures to tendons are common and costly, and no clinical consensus exists on the appropriate treatment and rehabilitation regimen to promote their healing as well as full recovery of functionality.

Temperature and yield stress characterization of electric contacts by 3D numerical simulation [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2005
Electric contacts of riveted type are analyzed by 3D simulation of their mechanical, electrical and thermal characteristics. Special emphasis was put on dependencies of contacts’ temperatures on chosen contact material and applied load conditions ...
